PURPOSE:To provide a cooler, for a board, which uses a vortex tube which can cool the inside of the board without a need of a complicated air-pipe-laying operation. CONSTITUTION:At least an air compressor 3, a heat exchanger 4 which cools compressed air and a vortex tube 9 into which cooled compressed air is blown are incorporated into the inside of a case 2. This assembly is attached to the outside face of a board 1, and the inside of the board 1 is cooled directly or indirectly by a cooling air which is generated by the vortex tube. |
