摘要： A cooling structure is provided. The cooling structure includes cooling surfaces on two confronting side surfaces; a plurality of double-sided-cooling power module 500, the heat receiving block 501 pinching the heating elements arranged in a vertical direction on the confronting side surfaces, first and second cooling devices 510, each including the heat radiating fins 503, disposed above the heating elements, extending in a horizontal direction, and a pressure contacting part configured to contact the heating elements and the receiving block with a pressure force. The heat radiation fins are blown from a side of the electric terminal.
