本発明の一態様は、冷媒を流通させる冷媒流路を有する複数の冷却管を、隣り合う該冷却管同士が連結されると共に両者の間に発熱部品を配置するための配置空隙が形成されるように並べて配置してなる熱交換部と、
上記冷媒流路へ冷媒を導入する冷媒導入管と、
上記冷媒流路から冷媒を排出する冷媒排出管とを備えており、
上記冷媒導入管及び上記冷媒排出管は、上記複数の冷却管のうち、該複数の冷却管の並び方向における一端である前端に配された前端冷却管から上記並び方向に延出されており、
該前端冷却管の剛性を向上させる剛性向上手段を備えており、
上記前端冷却管は、前方側に配された前方外殻プレートと、後方側に配されるとともに、上記前方外殻プレートに接合されて上記前方外殻プレートとの間に上記冷媒流路をなす空隙を形成する後方外殻プレートとを備えており、
上記冷媒導入管及び上記冷媒排出管は、上記前方外殻プレートに接合されており、
上記剛性向上手段として、少なくとも、上記前方外殻プレートの厚さを、上記後方外殻プレートの厚さに比べて大きくしていることを特徴とする積層型冷却器にある。 In one embodiment of the present invention, a plurality of cooling pipes having a refrigerant flow path for circulating a refrigerant are connected to each other, and an arrangement gap for arranging a heat-generating component is formed between the two cooling pipes. A heat exchanging part arranged side by side,
A refrigerant introduction pipe for introducing the refrigerant into the refrigerant flow path;
A refrigerant discharge pipe for discharging the refrigerant from the refrigerant flow path,
The refrigerant introduction pipe and the refrigerant discharge pipe extend in the arrangement direction from a front end cooling pipe arranged at a front end which is one end in the arrangement direction of the plurality of cooling pipes among the plurality of cooling pipes,
Comprising rigidity improving means for improving the rigidity of the front end cooling pipe ,
The front end cooling pipe is disposed on the front side and the front outer shell plate, and on the rear side, and is joined to the front outer shell plate to form the refrigerant flow path between the front outer shell plate and the front outer shell plate. A rear shell plate that forms a gap,
The refrigerant introduction pipe and the refrigerant discharge pipe are joined to the front outer shell plate,
As the rigidity improving means, at least the thickness of the front outer shell plate is made larger than the thickness of the rear outer shell plate .

また、上記剛性向上手段として、上記前端冷却管に重ね合わされた補強プレートをさらに備え、該補強プレートは、上記前端冷却管における上記冷媒導入管及び上記冷媒排出管との接続部の周囲に接合された接合部を有することが好ましい。この場合には、上記補強プレートを用いて、上記前端冷却管の剛性を確実かつ容易に向上することができる。これにより、上記前端冷却管の変形を確実に防止することができる。 Further, as the rigidity improving means, further comprising a reinforcing plate superimposed on the front end cooling pipes, reinforcing plates, joined to the periphery of the connecting portion between the refrigerant inlet and the refrigerant discharge pipe at the front end cooling pipe It is preferable to have a joined portion. In this case, the rigidity of the front end cooling pipe can be reliably and easily improved by using the reinforcing plate. Thereby, a deformation | transformation of the said front-end cooling pipe can be prevented reliably.
