PROBLEM TO BE SOLVED: To provide an art to exert a compression force on a laminate while simply adjusting variation in length of the laminate in lamination direction in a power converter equipped with the laminate in which power cards and coolers are laminated.SOLUTION: A power converter disclosed in the present specification comprises: a laminate 2 in which a plurality of coolers 3 and a plurality of power cards 5 each storing a semiconductor element are laminated; and a case 8 storing the laminate 2. In addition, selected blocks 6 selected based on a length L0 in a lamination direction of the laminate 2 out of a plurality of blocks having thicknesses different in thickness from each other are fixed to the inside of the case 8. The laminate 2 is sandwiched between an inside surface 82 of the case 8 and a lateral face 63 located in a thickness direction of the selected blocks 6 while being compressed in the lamination direction.SELECTED DRAWING: Figure 3 |
