Abstract
(EN)
According to the present invention, a plurality of first heat exchange tubes (20) are disposed such that flat surfaces thereof face each other and form a main body (12). A second heat exchange tube (30) is adjacent to one surface (12a) of the main body (12). A core case (40) has a cover part (93) for covering the surface (12a) of the main body (12) and the second heat exchange tube (30). When seen from a direction along the flow of a first heat medium, at least a portion of the cover part (93) is formed along the surface (12a) of the main body (12) or an outer peripheral surface (33) of the second heat exchange tube (30).

Selon la présente invention, une pluralité de premiers tubes d'échange de chaleur (20) sont disposés de telle sorte que des surfaces plates de ceux-ci se font mutuellement face et forment un corps principal (12). Un deuxième tube d'échange de chaleur (30) est adjacent à une surface (12a) du corps principal (12). Un boîtier de noyau (40) possède une partie de couvercle (93) pour recouvrir la surface (12a) du corps principal (12) et le deuxième tube d'échange de chaleur (30). Vu depuis une direction le long de l'écoulement d'un premier fluide thermique, au moins une portion de la partie couvercle (93) est formée le long de la surface (12a) du corps principal (12) ou d'une surface périphérique externe (33) du deuxième tube d'échange de chaleur (30).
