Power converter
A power converter includes a power conversion module including a heat generation device, a cooling medium path through which a cooling medium for cooling the heat generation device flows, and a cooling medium collection unit disposed facing the power conversion module and collecting the cooling medium that has cooled the heat generation device. The power conversion module includes a first heat conductive member in which a first flow path forming a part of a cooling medium path is provided. The cooling medium path includes a first connecting pipe connecting a first flow path provided in the first heat conductive member with the cooling medium collection unit. The power converter further includes a first support tool provided in at least one of the cooling medium collection unit and the power conversion module and supporting the first connecting pipe.
