<p><P>PROBLEM TO BE SOLVED: To provide a power conversion apparatus, whose miniaturization is easy and pressurizing member is easy to install, and a manufacturing method of the power conversion apparatus. <P>SOLUTION: A power conversion apparatus 1 includes: a laminated body 3 obtained by laminating a plurality of semiconductor modules 30 and cooling tubes 310; and a frame 2 in which the laminated body 3 is accommodated. A pressurizing member 4 that pressurizes the laminated body 3 in a lamination direction is arranged for one end of the laminated body 3 in the lamination direction. The pressurizing member 4 includes a pressing plate 40 abutted on the laminated body 3, a support plate 41 abutted on an inside surface 201 of the frame 2, and an elastic body 42 provided between the pressing plate 40 and the support plate 41. The pressurizing member 4 is disposed between the laminated body 3 and the inside surface 201 of the frame 2 under a compressed state where the elastic body 42 is compressed in the lamination direction. The pressurizing member 4 includes engagement means (composed of an engaging part 412 and an engaged part 401) that is constructed so as to be able to have the pressing plate 40 and the support plate 41 engaged with each other while maintaining a state where the elastic body 42 is compressed further from the compressed state. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
