PURPOSE:To position fins without using any jig, etc., and, at the time of brazing and soldering the fine, to maintain the fins in erected states at appropriate positions by eliminating the shifting or tilting of the films so as to improve the working efficiecy at the time of fabricating a cooling body. CONSTITUTION:In a cooling device provided with a cooling body constituted by fixing multiple fins 14 to a flat plate 12 in parallel, the fins 14 are formed in Z-shapes and multiple punched holes 14d and projections 14f are provided in a line intersecting the bending direction of the fins 14 at right angles on the lower short side of each fin. At the time of fixing the fins 14 on the flat plate 12, the projections 14f of one fin 14 are fit in the holes 14d of another fin 14. |
