Condenser Integrated with Receiver Dryer {Condenser Integrated with Receiver Dryer}

The present invention relates generally to a condenser for converting a gaseous refrigerant into a liquid refrigerant in a cooling system, and more particularly, a plurality of parallel condenser tubes and two condenser header pipes integrally coupled to both ends of the condenser tubes. By condensing one of the condenser header pipes of the condenser structure and the case member for the receiver dryer, the number of parts and the volume of the entire device can be reduced, thereby reducing the work process and reducing the material cost. The present invention relates to a capacitor in which a receiver dryer is integrated.

In general, a cooling system uses a refrigerant (freon, R-132a, etc.) that can evaporate even at low temperatures as a working fluid to take advantage of heat dissipation from the surroundings when the liquid evaporates. Compression and condensation , Cycles of expansion, evaporation.

In this cycle, which is partially shown in FIG. 1, the refrigerant flows into the compressor 10 through the low pressure tube 11 in a gas state of low temperature and low pressure, and then is compressed into a high temperature and high pressure gas state to thereby compress the high pressure tube 13. Outflow. The refrigerant in the high temperature and high pressure gas state transmitted from the high pressure tube 13 is discharged to the outside while passing through the condenser 20 to change into a liquid refrigerant of low temperature and high pressure. The liquid refrigerant flowing out of the condenser 20 is removed from the foreign matter and water while passing through the receiver dryer (30). The low temperature high pressure liquid refrigerant then passes through the high pressure pipe 15 to reach an expansion valve (not shown), converts into a low temperature low pressure liquid state, and then flows into an evaporator (not shown). In the evaporator, the low temperature low pressure liquid refrigerant evaporates while absorbing heat from the surroundings, is converted into a low temperature low pressure gas, and returned to the compressor 10 again. In this process, cold air formed around the evaporator may be forced into the vehicle through the blower.

Typically, the receiver dryer 30 is a device for removing foreign matter and water by passing the liquid refrigerant flowing out of the condenser 20, and has a configuration in which a desiccant such as a filter and a zeolite is filled in a generally long cylindrical case. When the role of the receiver dryer 30 is not smoothly performed, clogging due to foreign matters may occur, and thus the performance of the cooling system may be deteriorated. In addition, if the situation is left for a long time, the compressor 10 may be burdened. Can cause system failure.

Hereinafter, with reference to the accompanying drawings, the present invention will be described with specific examples. In the following description, in order to facilitate the understanding of the invention, a vehicle cooling system is described as an example, but the present invention is a vehicle, agricultural machinery, heavy equipment or aircraft, ships, as well as air conditioners, refrigerators, showcases, etc. It can be applied throughout the cooling system.

2 shows a structure of a condenser (condenser) of a vehicle cooling system, that is, a condenser that converts a gaseous refrigerant into a liquid refrigerant.

In general, a condenser includes a plurality of condenser tubes constituting a thin and narrow passage in parallel, and a condenser tube portion 140 in which heat dissipation fins are arranged between the condenser tubes. The gaseous refrigerant liquefies, that is, condenses while releasing heat to the outside while passing through the condenser tube inside the condenser tube portion 140. In order to facilitate heat dissipation to the outside, each condenser tube forms a narrow and long passage and heat dissipation fins are connected to the outer surface thereof. Typically, a separate pen motor (not shown) is operated outside the condenser to generate wind to facilitate heat dissipation.

A receiver dryer is a kind of filtering device for removing foreign matter and water by passing liquid refrigerant generally flowing out of a condenser. The receiver dryer is filled with a desiccant such as a filter and a zeolite in a generally long hollow cylindrical case and passes through a passage through which the refrigerant passes. It has a formed configuration.

The condenser 100 incorporating the receiver dryer according to the present invention provides a feature that the condenser header pipe, preferably the outflow header pipe through which the liquid refrigerant flows out, and the case member for the receiver dryer are integrally formed. As a result, the number of parts and the volume of the entire device can be reduced, which shortens the work process and reduces the material cost.

In the illustrated example, in particular, the refrigerant outlet side header pipe 160 is shown integrally formed with a case portion 167 for constituting the receiver dryer 160b side by side along its length. The receiver dryer 30 illustrated in FIG. 1 can be configured by filling the case part 167 with a drying agent such as a filter and a zeolite and forming a passage pipe or the like so that the refrigerant passes therethrough.

In the illustrated example, the case part 167 for constituting the receiver dryer 160b is in the form of a hollow cylindrical pipe. However, according to the present invention, the case part 167 is not only cylindrical, and various cross-sectional shapes as necessary. For example, those skilled in the art will readily understand that a pipe having a rectangular cross section is also possible.

Meanwhile, as illustrated, header pipes 120 and 160 are coupled to both ends of the condenser tube 140. The header pipe is an intermediary means for connecting a plurality of passages consisting of these plurality of condenser tubes and one passage such as a high pressure tube, and may be generally shaped like a single hollow rectangular tube or a cylindrical tube.

Both ends of the condenser tubes are communicated between the two header pipes 120 and 160 by, for example, brazing, in contact with a plurality of coupling holes formed at regular intervals on one side of the header pipes 120 and 160. Can be fixed in parallel.

Here, the brazing treatment is a technique of heating two or more base materials by heating them at a high temperature of 450 ° C. or higher but below the melting point of the base material to be joined, and using a separate material without damaging the base material. Since the melting point of lead used in the soldering process is about 327 ° C, a special material such as clad material is required for the brazing process. This clad material is a material that melts and melts, for example, between 500 and 600 ° C. Since the aluminum, which can be used as the condenser tube base material and the header pipe base material, has a melting point of about 660 ° C, the condenser parts are heated to, for example, 600 ° C. It is an essential material in the aluminum brazing bonding process. In the prior art, the cladding material is typically applied throughout the header pipe surface.

The condenser 100 incorporating a receiver drier provided according to the present invention is provided with a feature in which the header pipe is formed by assembling two separate parts instead of one part and joining each other through a brazing process. This is to enable to reduce the amount of clad material applied to the header pipe surface, and consequently can be provided with the advantage that the surface area to which the expensive clad material is applied can be reduced.

To this end, as illustrated in FIGS. 4 to 6, the header pipes 120 and 160 may be formed by assembling two parts of the U-shaped header tubes 121 and 161 and the header cover members 123 and 163. . The assembly of the two parts (assembly of the U-shaped header tube 121 and the header cover member 123 and the U-shaped header tube 161 and the header cover member 163) is completed by brazing treatment using clad material.

The U-shaped header tubes 121 and 161 are joined to the condenser tubes on one side, and to the header cover members 123 and 163 on the other side. The U-shaped header tubes 121 and 161 are joined to the surface of the U-shaped header tubes 121 and 161 only. Clad material that is a brazing binder is applied.

The header cover members 123 and 163 are joined to the U-shaped header tubes 121 and 161 to form the spaces 120a and 160a of the header pipe, and the cladding material does not need to be applied to the surface thereof. Accordingly, since the header cover members 123 and 163 are relatively freely designed without any cost increase, the fastening guide plates 125 and 165 or the case unit 167 for the receiver dryer are described in detail below. Design freedom to integrally mold additional shapes such as

As described above, the header pipes 120 and 160 of the present invention assemble the U-shaped header tubes 121 and 161 to which the cladding material is applied only to the joints on the surface and the header cover members 123 and 163 to which the cladding material is not applied. By the brazing treatment, the U-shaped header tubes 121 and 161 and the header cover members 123 and 163 can be formed to be joined to each other by a clad material applied to the U-shaped header tubes 121 and 161.

Both legs 1234, 1236; 1634, 1636 of the header cover members 123, 163 may be assembled so as to contact the outer surfaces thereof with each other.

The configuration in which the U-shaped header tube and the header cover member are brought into contact with each other by two leg portions has the advantage of increasing the area for each part where the two parts, that is, the U-shaped header tube and the header cover member are joined to each other by brazing treatment. Can provide.

In addition, in order to ensure that the U-shaped header tube and the header cover member are firmly coupled, as illustrated, the outer side of the leg portions 1234, 1236; 1634, 1636 of the header cover members 123 and 163, that is, the legs. On the outer side of the additional base surface and the portion that follows, hook portions 1235, 1237; 1635, 1637 may be formed to insert the ends of the legs 1214, 1216; 1614, 1616 of the U-shaped header tube.

According to the present invention, the header cover member 123 of the inlet side header pipe 120 may be further integrally formed with a fastening guide plate 125 which extends and protrudes along its length direction. In the case of the outlet side header pipe 160, the fastening guide plate 165 may be integrally protruded outwardly along the length direction of the case part 167 integrally formed outside the header cover member 163. .

The fastening guide plates 125 and 165 are parts that can be used to fasten the condenser 100 inside the vehicle. In particular, a plurality of fastening holes 125a and 165a may be formed by punching a plurality of fastening guides 125 and 165 along the fastening guide plates 125 and 165. This provides an advantage that the parts can be shared by simply mounting the fastening brackets to different fastening holes in the vehicle of various structures.
