Abstract
A cooling type switching element module includes an outer conductor pipe, an inner conductor pipe that transmits electric power in conjunction with the outer conductor pipe, and first and second switching elements. The first switching elements are provided on outer surfaces of the outer conductor pipe, and the second switching elements are provided on outer surfaces of a projecting portion of the inner conductor pipe. A coolant flows within the inner conductor pipe, and outside the outer conductor pipe. The first and second switching elements are cooled from both sides by the coolant flowing within the inner conductor pipe, and by the coolant flowing outside the outer conductor pipe. By employing the above-described structure, it is possible to provide a switching element module having a cooling function, in which improved cooling performance, improved electrical performance, and downsizing are achieved.
