Abstract
The present disclosure relates to a switching semiconductor device and a cooling apparatus thereof. The cooling apparatus of the switching semiconductor device of the present disclosure comprises a first heat dissipation plate configured to facilitate heat dissipation of a surface of the semiconductor device at an installation space, and a second heat dissipation plate disposed inside the installation space along a thickness direction of the first heat dissipation plate. The installation space is formed in a predetermined size at the surface of the semiconductor device, and the second heat dissipation plate is configured to contact the first heat dissipation plate so as to allow heat exchange. Accordingly, a heat dissipation area may be increased without increasing a size of the installation space.
