BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite electronic product, and more particularly, an inlet or a heat dissipation port is formed at one side and an opposite side of a housing, and a VCR assembly (magnetic recording and playback unit), a DVD assembly, and a power supply unit are installed in a zigzag multilayer structure. The present invention relates to a composite electronic product capable of maximizing heat dissipation efficiency while minimizing noise interference between each other.

Generally, a composite electronic product is a product equipped with a video cassette recorder (hereinafter referred to as a VCR) and a DVD player using a hard disk (hereinafter referred to as an HDD) or a digital video disk (hereinafter referred to as a DVD).

VCR is a conventional video recording / playback product that records / reproduces necessary video and audio data by directly applying physical effects such as magnetism to the magnetic tape of the video cassette. There is a safety of the playback function that can perform playback without being affected, and since it has been most popular for a long time, the rental and acquisition of video contents are simple and easy, while the physical action is likely to damage the media, If the physical damage is increased by repeating the recording several times, the image quality deteriorates rapidly, so the service life is short, the video tape needs to be replaced, and the magnetic tape needs to be physically rotated to watch the desired section. It is inconvenient to use, and because of the large size of the media, And move and uncomfortable, there was a relatively large issue size of the VCR itself.

Because DVD players are stored as digital signals, editing and transmission of images are very convenient, and the hard disk can be detachably configured, so that video and audio data can be recorded and stored in large amounts, thereby reducing the amount of storage space or stored video and audio data. It is convenient to replace and use without having to copy from other storage media. Therefore, the recorded video data and audio data are stored on digital video media such as hard disk or small sized DVD which can be easily moved. You can also play back stored video and audio data by connecting and connecting to a remote PC or DVD player.

Therefore, the composite electronics have the advantages of a VCR that is easy to obtain video contents and can be stably reproduced even if data is damaged, and a DVD player that is easy to carry by using a small storage medium and obtains high quality even during repeated playback. The product configuration eliminates the inconvenience of purchasing and installing each product.

However, since the two products, VCR and DVD player, must be housed in a single housing, the number and volume of components are relatively increased compared to those of separate products. In addition to requiring a larger data storage space than a hard disk, the surveillance video data recorded through movies, music videos, and CCTVs is operated by a combination of search and indexing functions. The speed must also be excellent, so the size of all the components required for this is relatively large, thus increasing the overall size of the product.

Therefore, above all, it was required to make the size of each product embedded in the housing compact and efficiently to make the size of the product itself compact, and to provide sufficient spacing to reduce the interference of noise and the deterioration of components due to heat. There was a tendency that the selection of the proper position did not sufficiently be considered, for example, the amplifier portion that generated the highest heat was integrally formed in the VCR assembly, and the power supply portion was disposed on the same plane adjacent to the VCR assembly sensitive to noise interference.

In recent years, the miniaturization and functionality of parts have been increased, and noise and heat generation have been relatively reduced, which makes it possible to reduce the size to a sufficiently desired size, and to reduce the interference and improve the heat generation efficiency. There is a need for a new design of housing and component layout to address failures and shortened service life.

1 is a perspective view showing an embodiment of a conventional composite electronic product.

As shown, a conventional composite electronic product includes a VCR mechanism portion 50, a VCR substrate portion 70, a DVD mechanism portion 40, a DVD substrate portion 60, a power supply portion 80, and a housing 30 surrounding them. ).

The DVD board 60 and the VCR board 70 are provided on both sides at the rear surface of the housing 30.

The DVD substrate portion 60 includes an amplifier portion (not shown), and a DVD mechanism portion 40 partially stacked on the front end is disposed.

The VCR substrate portion 70 is disposed in front of the VCR mechanism portion 50, which is overlapped and mounted on the front, and the power supply portion 80 integrally formed at the corner is disposed in the rear.

The functions and interactions of the conventional composite electronic product having such a configuration are as follows.

When the proper power is supplied through the power supply unit 80, the VCR board unit 70 and the DVD board unit 60 are activated, and whether the mechanism unit 50 or 40 corresponding to each other is inserted or not, or the progress of reproduction is performed. Judging and optionally initiating the operation.

When the medium is inserted, the analog medium inserted through the right door (not shown) of the front panel 32 is disposed to contact the head while being guided to the VCR mechanism part 50, and the head is rotated and stored in the medium. Data is recognized and converted into a signal, and the signaled data is transmitted to the VCR board unit 70.

Similarly, a digital medium is inserted through a left door (not shown) of the front panel 32, and the image and sound information contained in the seated and inserted digital medium are digitally recorded on the medium by driving the DVD mechanism unit 40. FIG. The signal is read, and the read signal is transmitted to the DVD board unit 60.

Upon reception, the amplifier unit generates an appropriate voice signal through filtering such as sound, amplification, or attenuation selectively according to conditions, and the voice signal is transmitted to an independently constructed or built-in speaker (not shown). do.

As shown in the figure, each substrate portion 60, 70 is attached to the bottom surface of the housing 30, and each mechanism portion 40, 50 is also overlapped so that all components are substantially on the same plane. This is to provide a more compact size than the multi-layered structure with the height difference between the components.

In addition, the amplifier part is integrally formed in the DVD board | substrate part 60, and the power supply part 80 is integrally comprised as a part of VCR board | substrate part 70, and it is intended for the same reason.

In particular, the power supply unit 80 is provided as a separate substrate in the existing configuration has been improved to the upper side of the substrate unit (60, 70) is improved, by placing all the parts on a single plane to greatly reduce the overall height of the product Worked.

In addition, although the power supply unit 80 generates noise, it is formed adjacent to the VCR board unit 70 which is sensitively interfered with the fine noise, when the DVD board unit 60 is subjected to noise interference of a certain degree or more. This is to avoid this because it may not play at all.

However, compared with the conventional power supply unit 80, the recent power supply unit is considerably improved so that the noise generation degree is lowered, so that no significant noise is generated such that the DVD board unit 60 cannot reproduce, so that there is no meaning of being spaced apart. On the other hand, since the VCR board unit 70 shows minute noise as visually identifiable, only the problem that the recording / reproducing image quality of an analog medium is generally deteriorated remains, and in order to compensate for this problem, the VCR mechanism unit 50 is particularly When additional shields are additionally installed to reduce interference with the head, there is a problem in that the process and the cost are added.

In addition, since the amplifier part generates the most heat among the components of the composite electronic product, there is a problem in that deterioration of other components is promoted by heat generation and further shortening the life of the product, and a separate fan is provided to improve heat dissipation efficiency. In this case, there was a problem in that a process and a cost were added.

In addition, since the bottom portion of the housing 30 is completely blocked by the substrate portions 60 and 70 and the mechanism portions 40 and 50, when the internal air causes upward convection due to the generation of high heat, It was difficult to form an opening for air inflow.

The present invention is to solve the above-mentioned conventional problems, the object of the present invention is to add a small height difference without increasing the production cost and the burden of the process by not adding a separate component is compact The present invention provides a composite electronic product that can be manufactured in a size and prevents degradation of reproduction / recording quality caused by noise, and can compensate for deterioration of components due to heat generation and further shortening of product life.

In order to achieve the above object, the present invention provides a housing including a bottom frame and a top cover, and a composite electronic product including a head mounted VCR assembly, a DVD assembly, a power supply part, and an amplifier part respectively embedded in the housing. A plurality of air inlet is formed on the front side of the top cover and a plurality of heat dissipation holes are formed on the rear side of the top cover, the VCR assembly, DVD assembly, the amplifier portion is installed in a zigzag multi-layer structure to ensure the air flow path from the inlet to the heat dissipation opening It features.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention.

2 to 4 are plan, front and side views, respectively, of the composite electronic product according to the preferred embodiment of the present invention.

As shown in these figures, according to a preferred embodiment of the present invention, a VCR assembly 1 for recording / reproducing analog medium largely, a head portion 2 mounted on the VCR assembly 1, and a digital medium are recorded. DVD assembly 3 to be reproduced, a power supply section 4 and an amplifier section 5 formed of individual substrates, and a housing 10 surrounding them.

The housing 10 is generally composed of a bottom frame and a top cover, an air inlet 12 is formed in the bottom frame, a heat dissipation port 14 is formed in the top cover, and the heat dissipation port 14 is installed in front of the front panel. It is located at the rear to avoid the thermal effect because it may have a thermal effect on the medium to be inserted through, the inlet 12 is the inlet air is diffused as much as possible inside the housing 10 to absorb the heat and heat sink 14 It is located on the front side of the bottom frame located diagonally from the heat dissipation port 14 so that it can be discharged through.

Since the high temperature is generated in the amplifier part 5, the air introduced into the inside of the amplifier part 5 absorbs heat by absorbing heat and then contacts other components, and thermally affects the heat discharge hole 14. It is installed adjacent to the heat sink 14 so as to be discharged directly through.

Since the DVD assembly 3 has a relatively low heat generation and maintains almost the same temperature even when the incoming air is in direct contact with the DVD assembly 3, the DVD assembly 3 is spaced apart on the inlet 12 so as to guide the introduced air to other components without changing the temperature.

Since the VCR assembly 1 has a large area, it is installed lower in parallel with the DVD assembly 3 so that the VCR assembly 1 enters through the inlet 12 and touches the bottom surface of the DVD assembly 3 with little increase in temperature. The approaching air is configured to be in direct contact with the head 2 having a relatively high calorific value.

Similarly, the power supply unit 4 is also installed at the rear of the DVD assembly 3 in the inner space in parallel with the VCR assembly 1 and lower than the DVD assembly 3, so that air which is diffused on the bottom of the power supply unit 4 and approaches the power supply unit 4 is provided. It is configured to more effectively radiate heat than in the case of contacting from above and contacting from below.

Of course, a plurality of openings may be selectively formed on all sides of the housing in addition to the bottom frame and the top cover to facilitate the introduction and discharge of air.

In addition, since the power supply unit 4 that generates noise should be spaced apart diagonally as much as possible to minimize noise interference on the head 2 mounted on the VCR assembly 1, as described above, It is preferable to be arranged side by side rearward.

The function and interaction of the composite electronic device having such a structure are performed as follows.

When power is supplied through the power supply unit 4 and the VCR assembly 1 and the DVD assembly 3 are activated, noise and heat such as noise, magnetic and electromagnetic waves are generated from all components, and the power supply unit generates a relatively large amount of noise. This causes noise interference to the head 2 and the DVD assembly 3 which are sensitive thereto.

Therefore, the internal air is heated up by the heat generated as the electronic component embedded in the housing 10 is activated, and the air whose temperature is high forms an upward airflow, and the airflow opening 14 is formed on the top cover. At the same time as the outside air is discharged through the air inlet 12 of the bottom frame, heat dissipation by natural convection is achieved.

Now, the air flow formed through the zigzag multi-layered structure of the present invention for improving the efficiency of heat dissipation by natural convection is as follows.

When heat is generated inside the operated composite electronic product, as mentioned above, the air heated up is discharged to the radiator 14 by natural convection and at the same time, the outside air enters through the inlet 12, and the outside air at room temperature enters the inlet. The bottom surface of the DVD assembly 3 which passes through the 12 and is formed to be spaced apart on the inlet 12 is preferentially contacted.

The DVD assembly (3) has less heat generation than the VCR assembly (1), the power supply unit (4), and the amplifier unit (5) due to its operation characteristics, so that even if the air at room temperature comes into contact, the temperature difference is not large. In the meantime, as the internal pressure of the housing increases as the air flow escapes, the air gradually expands as the air continues to enter through the inlet 12.

The bottom of the DVD assembly 3 guides the air flow by entering and diffusing the air directly in contact with it, and the guided air flow is approached to the surrounding VCR assembly 1 and the power supply 4 which are installed lower. .

Since the power supply unit 4 and the VCR assembly 1, especially the head 2, have relatively high heat generation, the temperature is kept substantially constant so that the air close to room temperature absorbs a considerable amount of heat by contacting them. It is moved toward (14), and is discharged to the outside through the heat radiation port 14 while absorbing again the high heat generated from the amplifier portion 5 provided adjacent to the heat radiation port (14).

On the other hand, when the power is supplied, the power unit generates noise. The DVD assembly 3 is hardly affected when the noise interference is insignificant, but when exposed to considerable noise, the digital information cannot be read and recording / playback is completely impossible. Although the VCR assembly 1 can operate even when exposed to considerable noise, the stability of the playback function is excellent. However, since the image quality is degraded by displaying noise during video recording / playback due to the influence of minute noise interference, the level of technology is low. The conventional power supply unit 4, which has generated this low noise, is provided as far apart as possible so that noise interference to the head 2 is minimized.

However, since the power supply 4, which is widely used in recent years, does not generate serious noise, it does not need to be separated from the DVD assembly 3, while the VCR assembly 1, especially the head, Is spaced apart as far as possible so as to improve the deterioration of image quality that may occur during recording / reproduction, so that noise generated from the power supply unit does not cause interference to the head 2.

According to the preferred embodiment of the present invention as described above, the VCR assembly, particularly the head, which is sensitive to noise interference, can avoid noise interference from the power supply unit, and the head and the power supply unit which generate relatively high heat from the DVD assembly with less heat generated by the air introduced therein. After the last contact with the high-heating amplifier, it is released and the effective heat dissipation by natural convection is eliminated without the need for a separate forced heat dissipation device such as a fan. You will receive less.

As described above, the composite electronic product according to the present invention does not add a configuration or a process of a new component, but instead, the heat generating portion and the amplifier portion are constituted by separate substrates and placed in place, thereby preventing the influence of interference due to noise. Minimizes, prevents deterioration of components by the heat generating part, and can effectively release internal heat through air inlet and heat dissipation port formed at the optimum position and securing the proper flow path without the addition of forcible device such as a fan. Have
