Abstract
A liquid-cooled-type cooling device includes a casing having a top wall, a bottom wall, and a cooling-liquid passage, and a radiating member disposed in the cooling-liquid passage. The radiating member has a substrate and a plurality of pin-shaped fins. Longitudinally intermediate portions of the pin-shaped fins are brazed to the substrate. The substrate has a plurality of fin insertion holes, and the pin-shaped fins are inserted into the fin insertion holes of the substrate. A plurality of convex portions are integrally formed on the longitudinally intermediate portion of each pin-shaped fin. The substrate and the pin-shaped fins are provisionally fixed together by plastically deforming the convex portions such that they are crushed. In this state, the substrate and the pin-shaped fins are brazed together. The upper and lower end portions of the pin-shaped fins are brazed to the top wall and bottom wall, respectively, of the casing.
