Abstract
A power module cooling device includes a manifold cover and a fin plate contained in the manifold cover, wherein a cooling fluid is ejected perpendicularly to heating surfaces through cooling fins of the fin plate configured perpendicularly to the longitudinal direction of the manifold cover so that a vertical turbulent flow of the cooling fluid is generated, thereby securing cooling efficiency, and flow characteristics of the cooling fluid are improved, minimizing flow rate loss due to the vertical turbulent flow. respective cooling channel portions of the manifold cover corresponding to respective power modules have different cooling performances so that respective power modules are cooled in a balanced manner. Accordingly, cooling imbalance is removed, and the power modules are thus stabilized and maintain performance.
