PROBLEM TO BE SOLVED: To provide an easy-to-manufacture structure of a cooler, in which a pair of opposite side plates of a housing can perform cooling, respectively, by collision jet.SOLUTION: A cooler 10 has a housing 12 and a partition plate 15. The housing 12 has a pair of opposite side plates 12a, 12b, and refrigerant passes between the pair of opposite side plates. The partition plate 15 sections the space between the pair of opposite side plates into three layers in parallel with the side plate. The partition plate 15 is one metal plate bent into U-shape, and the space between the pair of opposite side plates 12a, 12b is sectioned into three layers by two opposite surfaces of the partition plate in U-shape. Furthermore, a dent 16 which projects outward of the U-shape is provided, respectively, in two opposite surfaces of the partition plate in U-shape, and a refrigerant spout 17 is provided in the bottom of the dent. The dent 16 and refrigerant spout 17 correspond to nozzles, and the refrigerant is ejected from the refrigerant spout 17 toward the side plates 12a, 12b. |
