PROBLEM TO BE SOLVED: To efficiently cool a battery and an inverter for a hybrid vehicle. SOLUTION: A high-voltage electric cooling device 1 is the one that cools the battery for feeding electricity to a traveling motor via the inverter and the inverter by cooling air, and comprises an electrical component box 70 that leads the cooling air led from a cooling-air inlet 11 to a cooling-air outlet 41 and a fan 60 that makes the cooling air led in from the cooling-air inlet 11. The electrical component box 70 comprises: a battery box 20 wherein the battery is provided and the cooling air flows; a heat sink case 30 wherein a heat sink for the inverter is provided, the cooling air flows and the inverter is installed outside thereof; and an outer box 50 that surrounds the battery box 20, the heat sink case and the inverter, and communicates the outlet for the cooing air in the battery box 20 and the inlet for the cooling air in the heat sink case 30. |
