Abstract:
To meet market demand on compactness and high power density, since the second generation direct water cooling modules, a closed-type cooler rather than an open-type cooler as used in our first generation modules has been employed to suppress thermal deformation. In the latest generation (fourth) structure reported in this paper, besides the optimization of coolant flow, fin-base thickness is further optimized to achieve both high cooling performance and high thermal cycling capability. The fin-base thickness and the height of the whole cooler are 1/5 and 1/2 of those in the first generation, respectively. While the thermal cycling capability is doubled.
