Abstract
This invention discloses a water-cooled radiator for an electric vehicle power module, comprising an inlet end, an outlet end, and a cavity. The cavity contains multiple fin regions arranged along the water flow direction. Among the multiple fin regions, at least one high-density fin region is included, such that at least one low-density fin region near the inlet end has a lower density than the higher-density fin region near the inlet end, and at least one low-density fin region near the outlet end has a lower density than the higher-density fin region near the outlet end. Similarly, among the multiple fin regions, at least one low-density fin region is included, such that at least one high-density fin region near the inlet end has a higher density than the lower-density fin region near the inlet end, and at least one high-density fin region near the outlet end has a higher density than the lower-density fin region near the outlet end.
