A cooling fluid flow channel inside a housing includes: a plurality of main flow channel pipes each disposed adjacent to the outer surface of the heat generating part, and each arranged along the outer surface of the heat generating part; an inflow-side collecting pipe; and an outflow-side collecting pipe. The plurality of main flow channel pipes each have, in its inside and adjacent to each of the upstream-side ends, a swirl generator. The swirl generator has a plurality of protrusions respectively disposed, along an inner wall surface of each of the main flow channel pipes and respectively protruding toward a center, in radial directions, of each of the main flow channel pipes. The plurality of protrusions respectively have tips being separated from each other to have a through flow channel allowing the cooling fluid, in the radial directions, of each of the main flow channel pipes.
