摘要： A cooling structure of a heating element includes: the heating element having at least one cooling surface from which a plurality of pin fins project; a heat receiving plate which has a shape complying with the cooling surface and in which holes are formed at positions facing each pin fin, each pin fin being movably inserted into the holes; a cooler which has a pair of clamping members that sandwich therebetween the heating element and the heat receiving plate while pressing the heating element and the heat receiving plate, and which cools the heat receiving plate; and a space securing part which is provided on the heat receiving plate and suppresses a distance between the pair of clamping members so as not to apply a pressing force by the clamping members to the heating element.

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, the heat receiving block pinching the heating elements arranged in a vertical direction on the confronting side surfaces, first and second cooling devices, each including the heat radiating fins, 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.
