  • Power converter and cooler
    Patent number: 10015913
    Abstract: A power converter, including a heat generating element, and a cooler that includes a heat receiving plate, a plurality of cooling fins and a baffle plate. The heat generating element and the plurality of cooling fins are respectively mounted on two different surfaces of the heat receiving plate. Each cooling fin is a plate of a rectangular shape, and the plurality of cooling fins are arranged in parallel to one another, surfaces of any adjacent two of the cooling fins defining a course for cooling air to flow therethrough. The baffle plate is provided across the plurality of cooling fins, and has a substantially rectangular surface in a direction perpendicular to a direction of the courses.
