FLUID HEATING DEVICE

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid heating apparatus and, more particularly, to a fluid heating apparatus capable of quickly heating a large amount of fluid to quickly obtain a large amount of hot water, ≪ / RTI >

Fluid heating devices, such as boilers, have been developed in recent years to provide a high thermal efficiency, low energy consumption, and reduced generation of noxious gases. As an example, there is a "fluid heating apparatus" of Korean Patent Application No. 2007-0043568.

This technique uses a planar heating element and includes a plurality of heating tubes having internal passageways through which fluids can flow and a plurality of heating tubes which are coated on the outer surfaces of the respective heating tubes and generate heat energy by the applied power source, And a plurality of connection tubes for connecting the plurality of heating tubes in series so that fluid can be heated while sequentially passing through the inner passages of the respective heating tubes.

Such a fluid heating apparatus uses a planar heating element having a very high energy efficiency, so that energy consumption can be reduced as much as possible. In addition, since the surface heating element is used, no harmful substances are generated during operation. Therefore, it is possible to supply environment-friendly warm air.

However, such a conventional fluid heating apparatus is disadvantageous in that it requires a large amount of heating water because the heating tubes through which the fluid passes are connected in series.

In addition, since the heating tube connected in series has a structure in which the heating medium once heated is repeatedly heated several times, there is a disadvantage that the energy efficiency is inferior. These drawbacks cause heating costs to rise.

In addition, the conventional fluid heating apparatus has a disadvantage in that a separate fluid replenishing tank is required to continuously supply the fluid to the heating tube.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fluid heating apparatus capable of heating a large amount of fluid more efficiently at a faster and less cost.

It is another object of the present invention to provide a fluid heating apparatus capable of quickly and rapidly obtaining a large amount of hot water by constituting a large amount of fluid to be heated faster.

It is still another object of the present invention to provide a fluid heating apparatus capable of continuously supplying fluid without a separate replenishing tank.

To achieve the above object, a fluid heating apparatus of the present invention is a fluid heating apparatus for heating a fluid, comprising: an introduction tube for introducing fluid; An inlet body having an introduction chamber for receiving and filling the fluid introduced into the introduction tube; A plurality of heating tubes installed upwardly from the inlet body so as to be connected in parallel to the inlet chamber of the inlet body and each having an inner passage through which the fluid of the inlet chamber can flow and flow upward; ; A planar heating element which is provided on an outer surface of each of the heating tubes and generates heat energy by an applied power source to heat a fluid flowing along an inner passage of the heating tube; An outlet body installed at an upper end of the heating tubes, the outlet body having a discharge chamber capable of collecting a high temperature fluid discharged from an internal passage of the heating tubes at one time; And a discharge pipe that discharges the high-temperature fluid collected in the discharge chamber of the outlet body to the outside.

Preferably, the heating tube is vertically installed from an upper surface of the inlet body to an upper outlet body so that a fluid, which is fully charged, can be introduced into the inlet chamber of the inlet body.

According to the fluid heating apparatus of the present invention, since the introduced fluid is simultaneously heated by the heating tube arranged in parallel, a large amount of fluid can be heated quickly. Therefore, a large amount of hot water can be obtained quickly and quickly at a time.

Further, since the structure is such that the flow of the fluid is controlled while controlling the flow from the lower part to the upper part, the fluid can be heated and discharged without interruption. Therefore, there is an effect that there is no need for a separate fluid replenishing tank for supplying fluid without interruption.

In addition, since a separate fluid replenishing tank is not required, the effect of cost reduction can be expected.

Further, since the structure is such that the flow of the fluid is controlled while controlling the flow from the lower part to the upper part, the fluid can be heated and discharged without interruption. Therefore, it is possible to obtain hot water of constant water pressure.

Hereinafter, preferred embodiments of the fluid heating apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, a fluid heating apparatus according to the present invention includes a lower inlet body 10 for introducing fluid, an upper outlet body 20 for discharging fluid, And a plurality of vertical heating tubes 30 connecting the body 10 and the upper outlet body 20 in parallel with each other.

The inlet body 10 is constituted by a rectangular box body and has a lower introduction pipe 12 and an introduction chamber 14 therein.

The lower introduction pipe 12 introduces fluid from the outside. For example, water, brine, oil, air, etc. are introduced. Here, it is preferable that the introduction pipe 12 is provided on the bottom surface of the inlet body 10.

The inner introduction chamber 14 is configured to receive the fluid introduced into the introduction tube 12. [ In particular, the fluid introduced through the inlet pipe 12 is configured to be charged from below.

The outlet body 20 is a rectangular box body and is disposed at an interval on the upper portion of the inlet body 10 and has an exhaust chamber 22 inside and an exhaust pipe 24 at the top.

The inner discharge chamber 22 is configured to collect the hot fluid passing through the plurality of heating tubes 30. In particular, the high temperature fluid passing through the plurality of heating tubes 30 is configured to be collected while being charged from the bottom to the top.

The upper discharge pipe (24) discharges the hot fluid collected and charged into the discharge chamber (22) to the outside. Here, it is preferable that the discharge pipe (24) is provided on the upper surface of the outlet body (20).

The plurality of heating tubes 30 are made of a material having heat resistance and low expansion characteristics such as a quartz tube and a ceramic tube and are provided with internal passages 32 that are both open, The fluid can pass through.

The heating tubes 30 are vertically arranged such that the lower end portion 30a thereof is fixed to the lower inlet body 10 and the upper end portion 30b is fixed to the upper outlet body 20, The internal passage 32 is configured to communicate with the introduction chamber 14 of the inlet body 10 and the discharge chamber 22 of the outlet body 20. [

The heating tube 30 having such a configuration connects the introduction chamber 14 of the inlet body 10 and the discharge chamber 22 of the outlet body 20 in parallel, The fluid filled in the introduction chamber 14 of the body 10 is introduced into the internal passage 32 and the introduced fluid flows along the internal passage 32 from the lower portion to the upper portion, (22).

3, the lower end 30a and the upper end 30b of the heating tube 30 are fixedly connected to the inlet body 10 and the outlet body 20, respectively, and the airtight means 40 ). ≪ / RTI >

The airtight means 40 includes a connection joint 42 that is threadedly coupled to the inlet body 10 and the outlet body 20 in a state of being coupled to the outer peripheral surfaces of the lower end 30a and the upper end 30b of the heating tube 30, A first O-ring 44 that hermetically blocks the connection joint 42 and the heating tube 30 from each other and a connection joint 42 and an inlet body 10 and an outlet body 30 Ring 20 that airtightly blocks each other.

The airtight means 40 hermetically blocks the lower end portion 30a of the heating tube 30 and the inlet body 10 and the upper end portion 30b of the heating tube 30 and the outlet body 20. Therefore, leakage between the heating tube 30 and the inlet body 10 and between the heating tube 30 and the outlet body 20 is prevented.

Referring again to FIGS. 1 and 2, the fluid heating apparatus of the present invention includes a planar heater 50 provided on an outer surface of the heating tubes 30.

The area heating element 50 is a kind of resistor and can be formed of a thin film by applying a conductive paint to the heating tube 30.

A plurality of electrodes 52 capable of applying power are attached to the surface of the planar heating element 50 at predetermined intervals. The electrodes 52 are formed to be annular along the circumference of the heating tube 30. The electrode 52 is preferably made of "silver" material.

Such an area heating element 50 heats the heating tube 30 while generating heat at a high temperature by a power source applied to the electrode 52 and moves along the inner passage of the heating tube 30 as the heating tube 30 is heated The flowing fluid is heated to produce high-temperature heating water.

Next, an operation example of the present invention having such a configuration will be described with reference to Figs. 1 and 2. Fig.

First, when a fluid is introduced into the inlet pipe 12 of the inlet body 10, the introduced fluid starts to flow into the inlet chamber 14 of the inlet body 10. At this time, the fluid introduced into the introduction chamber 14 starts to be charged from the lower part of the introduction chamber 14 to the upper part.

On the other hand, when the fluid is completely filled in the introduction chamber 14, the fluid in the introduction chamber 14 is simultaneously introduced into the inner passage 32 of the heating tubes 30, And starts to be transported upward along the inner passage 32.

At this time, the surface heating element 50 coated on the outer surface of the heating tube 30 generates heat energy while being operated by the applied electric power, and the generated heat energy heats the heating tube 30.

And the heated heating tube 30 heats the fluid being conveyed upward along the inner passage 32.

On the other hand, the fluid conveyed along the heating tubes 30 is heated to a high temperature by the heat energy of the planar heating elements 50, and the heated high-temperature fluid flows from the inner passage 32 of the heating tubes 30 And is introduced into the discharge chamber 22 of the outlet body 20 while being discharged.

The hot fluid introduced into the discharge chamber 22 begins to fill the discharge chamber 22 and is discharged to the exterior through the upper discharge pipe 24 when the discharge chamber 22 is fully charged. Therefore, a high-temperature fluid can be obtained.

According to the present invention having such a configuration, since the introduced fluid is simultaneously heated by the heating tube 30 arranged in parallel, a large amount of fluid can be rapidly heated. Therefore, a large amount of hot water can be obtained quickly and quickly at a time.

Further, since the structure is such that the flow of the fluid is controlled while controlling the flow from the lower part to the upper part, the fluid can be heated and discharged without interruption. Thus, there is no need for a separate fluid replenishment tank to supply fluid without interruption.

In addition, since a separate fluid replenishing tank is not required, the effect of cost reduction can be expected.

Further, since the structure is such that the flow of the fluid is controlled while controlling the flow from the lower part to the upper part, the fluid can be heated and discharged without interruption. Therefore, hot water of constant water pressure can be obtained.

Although the preferred embodiments of the present invention have been described above, the scope of rights of the present invention is not limited to these specific embodiments, but can be appropriately changed within the scope of the claims.
