Description

Integrated Heat Exchanger

The present invention relates to an integrated heat exchanger, the connection cap having a special structure between the first and the second header tank to facilitate the identification of the heat exchanger of the heat exchanger and the heterogeneous heat exchange medium is not mixed with each other An integrated heat exchanger provided.

The heat exchanger is installed on the heat exchange medium flow path of the cooling and heating system so that the heat exchange medium flowing therein absorbs heat from outside air or heats its own heat to the outside to cool and heat a predetermined space. To be able.

Here, a cooling system for cooling the room compresses a gaseous refrigerant in a compressor into a gaseous state of high temperature and high pressure, which is easily liquefied, and transfers the gaseous refrigerant to a condenser. Transfer to the valve.

Subsequently, in the expansion valve, the refrigerant, which has been phase-changed into a liquid state, is changed to a low-temperature, low-pressure wet-saturated vapor state by the throttling action and transferred to the evaporator. ), It evaporates itself, changes to gaseous state, and then repeatedly enters the compressor.

In addition, the automobile is equipped with an oil cooler separately for cooling the oil used for lubrication and airtightness of the engine or transmission.

However, as the oil cooler is composed of separate parts as described above, the production labor is increased, the productivity is lowered, the manufacturing cost is increased, and there is a problem in securing a space for installing the oil cooler.

In order to solve this problem, the condenser 100 and the oil cooler 200 integrated heat exchanger have been disclosed as referred to FIGS. 1 and 2.

As shown, the conventional heat exchanger of the condenser 100 and the oil cooler 200 is integrally formed with the condenser 100 through which the refrigerant is distributed and the oil cooler 200 through which the oil is distributed. The flow path is partitioned by the baffles 170 formed in the 210 and the second header tanks 140 and 240.

Here, the baffle 170 is provided in plural along the length direction of the first and second header tanks 110, 210, 140, and 240, and the heat shield plate 180 is disposed between the baffles 170. It is disposed in parallel with the 150, 250, the first and second header tanks (110, 210, 140, 240) is formed with a confidentiality check unit 173 for checking the airtight state of the baffle (170).

The confidentiality checking unit 173 is formed to penetrate the inside and the outside of the first and second header tanks 110, 210, 140, and 240 between the baffles 170. , 210, 140, 240 serves to check the leakage of refrigerant or oil circulating inside.

However, when the gap between the tubes 150 and 250 constituting the heat exchanger is less than a predetermined distance, that is, when the heat exchanger is miniaturized due to an improvement in performance, it is difficult to form the airtightness checking unit 173 or the airtightness checking unit is formed. A problem arises in that the size of the part 173 is too small to evaluate the airtightness.

The present invention has been made to solve the above problems, and an object of the present invention is a one-piece heat exchanger having a small or small gap between tubes constituting an integrated heat exchanger in which a heterogeneous heat exchange medium is circulated. It is to provide a heat exchanger.

In order to achieve the above object, the integrated heat exchanger of the present invention includes a plurality of tubes in which the first and second heat exchange media are separated and flow up and down, respectively, and are arranged in parallel at regular intervals; The first and second heat exchange media are introduced into the upper space (A) through which the first heat exchange medium is distributed and the lower space (B) through which the second heat exchange medium is distributed. A first header tank distributing each heat exchange medium to the plurality of tubes; A heat dissipation fin interposed between the tubes; The first and second heat exchange media circulated in the tube in the upper and lower spaces (A, B), respectively, and the second to discharge the collected first and second heat exchange media through the outlet pipe provided independently In the integrated heat exchanger consisting of a header tank,

In the first and second header tanks, the upper and lower spaces A and B are partitioned in surface contact with the ends of the upper space A and the lower space B, and trains are disposed parallel to the tube on one side. It is characterized in that the connection cap is provided with a slot formed so that the end of the plate is inserted.

Here, the heat shield plate is characterized in that it consists of the same tube as the tube connecting the upper space (A) through which the first heat exchange medium is distributed or the lower space (B) through which the second heat exchange medium is distributed.

In addition, the height of the slot is characterized in that formed larger than the height (d2) of the heat shield plate.

In addition, the connection cap is characterized in that the flange portion is formed so as to surround the end of the upper and lower spaces (A, B) of the first and second header tanks.

On the other hand, the connection cap is characterized in that the fixing bracket is formed.

As described above, according to the present invention, there is an effect that the airtightness confirmation is easy in the integral heat exchanger with a small or small gap between the tubes.

In addition, since the baffle is not provided or formed separately in the manufacturing process of the heat exchanger, there is a peculiar effect of reducing the labor cost and reducing the production cost.

DETAILED DESCRIPTION Details of the object and the technical constitution according to the present invention will be clearly understood by the following description with reference to the accompanying drawings showing preferred embodiments of the present invention.

Hereinafter, an integrated heat exchanger of the present invention having the configuration as described above will be described in detail with reference to the accompanying drawings.
