Original Abstract Submitted
heat of a heat-generating busbar is dissipated to a cooler via a heat spreader. a space between the heat spreader and the busbar is filled with a heat dissipation compound, and a labyrinth structure is formed around the outer periphery of a part for which dust-proofing is needed, thus providing dust-proofing. in the labyrinth structure, a first rib of the cooler is provided so as to surround the part and a second rib of a resin mold covering the part is also formed so as to surround the part. further, a first rib discontinuous section which is a partially discontinuous section with no rib is provided to the first rib, and the heat spreader and a filler are provided at the first rib discontinuous section, to achieve cooling and dust-proofing.
