Claim of US Patent No. 10,070,564

1. An electric power converter that performs power conversion comprising:a plurality of semiconductor modules with built-in semiconductor elements;
a plurality of cooling tubes stacked together with the plurality of semiconductor modules in a stacking direction; and
a metallic pressure member;
wherein the metallic pressure member includes:
a pressing surface that presses an outer cooling tube positioned at one of outer sides in the stacking direction among the plurality of cooling tubes in order to press-contact the plurality of cooling tubes and the plurality of semiconductor modules in the stacking direction; and
a heat-receiving surface that receives heat generated from an electronic component which is different from the plurality of semiconductor modules, by thermal conduction, and
wherein the heat-receiving surface of the pressure member superimposes a heat dissipating portion of the electronic component via an electrically insulating layer formed of an electrically insulating material.
