<P>PROBLEM TO BE SOLVED: To provide a cooling plate with a flow channel improved to enable to reduce temperature deflection by each part. <P>SOLUTION: In a cooling plate 100 provided with a flow channel 110 of cooling water absorbing heat of a heat generation body, the flow channel provides a larger volume of a center part 112 between a flow-in aperture 110a and a flow-out aperture 110b than a volume near the flow-in aperture 110a and the flow-out aperture 110b flowing in and out the cooling water, and a cooling water volume flowing through the center part 112 is made comparatively larger than that near the flow-in aperture 110a and the flow-out aperture 110b. With this, temperature deflection of each part can be restrained to a minimum, and deformation by thermal stress can be restrained. And also, a possibility having a bad influence such as resistance change on a cooling object like a fuel cell is reduced, so that stable performance can be assured. <P>COPYRIGHT: (C)2008,JPO&INPIT |
