Title: Stacked cooler
Inventor: INOUE SEIJI
IPC: H01L23/473
Filed: 2000-11-24
Abstract: PROBLEM TO BE SOLVED: To provide a stacked cooler which can make the cooling water effectively flow to the heat generating element requiring cooling water most. SOLUTION: An intermediate plate 3 comprises slits 9 forming a part of a cooling water path. The slits 9 comprises plural and parallel slits at regular intervals and is formed in diagonal direction with respect to the intermediate plat 3. However, the part of the slits 9 is divided by boltholes 8 as bolt holes are opened in the intermediate plate 3. On the other hand, the slits 9 passing through in the diagonal direction in an area A where the heat generating element are arranged extend to the both ends without divided by the bolt holes and communicate with a header. Thus it is possible to make the cooling water directly flow from the one header to the slits 9 passing through in the area A where the heat generating element are arranged and to flow to the other header without divided by the bolt holes 8.
