Abstract:
A semiconductor apparatus comprising:a substrate unit including a semiconductor element, and a pair of insulation substrates having thermal conductivity and holding the semiconductor element therebetween; first and second radiation members for radiation heat produced from the semiconductor element and defining a recess therebetween into which the substrate unit is inserted in an insertion direction in contact with the first and second radiation members; and a fixing member for fixing the substrate unit within the recess by being inserted into the first radiation member in the insertion direction of the substrate unit, wherein the second radiation member is in contact with the first radiation member to provide a thermal conductive pass between the substrate unit and the first radiation member; the first radiation member has a base portion and a protruding portion, wherein the base portion defines a refrigerant passage therein in which refrigerant flows, and the protruding portion protrudes from the base portion; and the fixing member includes a support member and a pushing member, wherein the support member is inserted into the protruding portion of the first radiation member, and the pushing member pushers the second radiation member in cooperation with the support member to hold the substrate unit within the recess.
