Abstract: A structure for mounting a box for containing high-voltage electrical equipment on a vehicle, so as to suppress increase in the number of parts, the weight of the vehicle, and the manufacturing cost by effectively using existing structural members of the vehicle body. The structure includes a frame member which is attached to the box and which extends to the rear side of the vehicle, and the frame member is combined with side frames which are structural members of the body of the vehicle. Typically, The frame member consists of two frame members which are respectively attached to the side frames at the right and left sides, and the structure further comprises a cross beam for coupling the frame members with each other, wherein the cross beam extends in the width direction of the vehicle.

Abstract: A high voltage electrical packaging box structure includes a case member having an opening portion, and a cover member which is detachably attached to the case member so as to cover the opening portion of the case member. The case member is installed so that a plane of the opening portion is inclined with respect to a horizontal plane. In the high voltage electrical packaging box structure, a pawl member is provided on one of the case member and the cover member, and a receiving member, which engages with the pawl member, is provided on the other one of the case member and the cover member.

Abstract: A heat sink-type cooling device is provided which can enhance the amount of heat dissipated without increasing the size of the fins, and which is miniaturized and has high cooling capacity. A heat sink-type cooling device comprises a heat sink that is provided with a passage through which coolant flows, and that removes heat from electronic devices contacting with the upper surface of the heat sink. Fin groups are provided in the passage, each of which is comprised of a plurality of fins that are disposed in parallel with the direction of the coolant flow and are aligned in the thickness direction thereof. Fins of a fin group and other fins of another fin group adjoining the fin group in the direction of the flow are placed at a distance in the thickness direction of the fins.
