본 고안은 박형 증발기에 관한 것으로, 특히 증발기내로 냉매를 공급, 회수하는 냉매 입출부를 보강판재에 일체로 형성하여 제작성을 향상시킨 박형 증발기에 관한 것이다.The present invention relates to a thin evaporator, and more particularly, to a thin evaporator which improves manufacturability by integrally forming a coolant inlet / outlet for supplying and recovering refrigerant into the evaporator.

자동차의 냉방기등에 사용되는 박형 증발기는 내부에 냉매통로가 형성되도록 한쌍의 판재로 구성시킨 단위 냉매 유통부재를 다수의 방열핀과 함께 다단으로 중첩시켜 냉매 유통부를 구성하고, 그 외면에 구비된 보강판재와 냉매 유통부재의 사이에는 냉매를 공급, 회수하는 냉매 입출부가 설치된 구성으로 되어있다.The thin evaporator used in the air conditioner of automobiles is composed of a pair of plate distribution members consisting of a pair of plate material to form a refrigerant passage therein with a plurality of radiating fins overlapping in multiple stages to form a refrigerant distribution section, and the reinforcement plate provided on the outer surface A coolant inlet / outlet for supplying and recovering coolant is provided between the coolant distribution members.

종래에 박형 증발기에 설치되는 냉매 입출부는 크게 프레스가공과 냉강단조에 의한 방법으로 제작되었다.Conventionally, the refrigerant inlet / outlet unit installed in the thin evaporator is largely manufactured by the method of press working and cold forging.

프레스가공의 경우는 미국 특허 제4487038호와 같이 알미늄브레이징판을 프레스가공하여 형성시킨 한쌍의 반 관상형 부재를 상접시켜 냉매 입출부를 제작하고, 증발기 외면에 구비되는 보강판재에는 냉매 입출부의 고정위치를 잡아줄수 있도록 고정돌기를 타발 가공하 냉매 입출부가 고정돌기에 얹힌 상태로 로(furnace)내에서 용접고정 시키게 되어있다.In the case of press working, as in US Pat. No. 4487038, a pair of semi-tubular members formed by pressing aluminum brazing plate is brought into contact with each other to produce a coolant inlet and outlet, and the reinforcing plate provided on the outer surface of the evaporator has a fixed position of the coolant inlet and outlet. After punching the fixing protrusion to hold it, it is fixed in the furnace with the refrigerant inlet / outlet on the fixing protrusion.

여기에서의 문제점은 냉매 입출부의 제작에 많은 공정을 필요로 하고, 보강판재에도 위치고정용 돌기를 타발하여야 하였으므로, 공수증가에 따른 생산원가가 상승되고 불량발생우려가 많아 공정관리에도 상당한 주위를 요구하였다.The problem here is that it takes a lot of process to manufacture the refrigerant inlet and outlet part, and also to fix the position fixing projections to the reinforcement plate, the production cost is increased due to the increase of airborne and there is a possibility of bad defects, which requires considerable attention to process management It was.

단조가공의 경우에는 냉매 입출구가 냉간단조에 의해 제작됨에 따라 생산단가가 과대히 높아지게 되고, 용접성이 떨어져 냉매 유통부에 완벽히 용접되지 못하므로 수리용접을 필요로 하는 등 많은 공정과 높은 생산단가를 요구함에 반하여 만족스러운 완제품을 얻지 못하고 있는 실정이다.In the forging process, as the refrigerant inlet and outlet are manufactured by cold forging, the production cost is excessively high, and because of poor weldability, it cannot be completely welded to the refrigerant distribution part, which requires a lot of processes and high production cost. On the other hand, the situation is not obtaining satisfactory finished products.

본 고안은 상기와 같은 사정을 고려하여 이루어진 것으로, 그 목적은 제조공정수를 줄이고 생산성을 향상시킴은 물론, 제조단가를 줄일 수 있는 박형 증발기를 제공함에 있다.The present invention has been made in consideration of the above circumstances, and an object thereof is to provide a thin evaporator capable of reducing the number of manufacturing processes and improving productivity as well as reducing the manufacturing cost.
