PURPOSE:To cool hot electric parts and improve the degree of freedom in arrangement of the electric parts by providing a vent hole opened through a board so that cooling air led to one surface of the board can be led to the electric parts. CONSTITUTION:This cooling device is equipped with a board 34 provided in such a way that the wind produced by an air blower 27 can be led to at least one side surface of the board 34, hot electric parts 36 mounted on the other surface of the board 34, and a vent hole 38 opened so that the wind led to the surface of the board 34 can be led to the parts 36. Accordingly, the wind produced by the device 27 is led to the electric parts. In addition, the wind also passes through a hole 38 opened through a mount 33 and vigorously blows off from the vent hole 38 through a wind path 39. Therefore, the hot electric parts 36 can be positioned even on the leeward side of large-sized electric parts 35 and the degree of freedom of arranging the parts 36 is improved, since the hot electric parts 36 are cooled and the heat production of the parts 36 is prevented. |
