Abstract
(EN)
A plurality of cooling plates (40) which are stacked inside a duct (30) are provided with first flow paths (43) and second flow paths (44). A first inlet communication part (47) and a first outlet communication part (48) allow the first flow paths (43) to communicate with each other in the stacking direction (H). A second inlet communication part (49) and a second outlet communication part (50) allow the second flow paths (44) to communicate with each other in the stacking direction (H). The first inlet communication part (47), the first outlet communication part (48), the second inlet communication part (49), and the second outlet communication part (50) are provided in a region at one side in a direction (L) which intersects the stacking direction (H) of the cooling plates (40), and intersects a direction (W) in which the first flow paths (43) and the second flow paths (44) are arranged. The internal dimension (D1) of the first inlet communication part (47) and the first outlet communication part (48) in the direction (W) in which the first flow paths (43) and the second flow paths (44) are arranged, is smaller than the internal dimension (D2) of the second inlet communication part (49) and the second outlet communication part (50).

Selon l'invention, une pluralité de plaques de refroidissement (40), empilées à l'intérieur d'un conduit (30), comprennent des premiers circuits d'écoulement (43) et des seconds circuits d'écoulement (44). Une première partie de communication d'entrée (47) et une première partie de communication de sortie (48) permettent la communication des premiers circuits d'écoulement (43) entre eux, dans la direction d'empilement (H). Une seconde partie de communication d'entrée (49) et une seconde partie de communication de sortie (50) permettent la communication des seconds circuits d'écoulement (44) entre eux, dans la direction d'empilement (H). La première partie de communication d'entrée (47), la première partie de communication de sortie (48), la seconde partie de communication d'entrée (49) et la seconde partie de communication de sortie (50) sont disposées dans une région au niveau d'un côté dans une direction (L) croisant la direction d'empilement (H) des plaques de refroidissement (40), et croisant une direction (W) de disposition des premiers circuits d'écoulement (43) et des seconds circuits d'écoulement (44). La dimension interne (D1) de la première partie de communication d'entrée (47) et de la première partie de communication de sortie (48), dans la direction (W) de disposition des premiers circuits d'écoulement (43) et des seconds circuits d'écoulement (44), est plus petite que la dimension interne (D2) de la seconde partie de communication d'entrée (49) et de la seconde partie de communication de sortie (50).
