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.

A manufacturing method of a heat conducting device includes following steps: providing a first plate, which includes a plate body and at least a heat conducting element, wherein the plate body has at least an inserting end disposed corresponding to the heat conducting element and defining a tube, and the heat conducting element is mounted at the tube; providing a second plate, which has a first opening end; disposing a first wick structure on an internal wall of the heat conducting element and a bottom surface of the plate body; disposing a second wick structure on an internal wall of the second plate; and connecting the plate body to the first opening end so as to connect the first plate and the second plate to form a chamber. Accordingly, the heat conducting device has a higher heat conducting efficiency.

A manifold structure and method of forming a manifold structure includes using an ultrasonic additive manufacturing (UAM) process to build up a solid structure, machining the solid structure to form a cavity and free-standing support pillars within the cavity, and using a UAM process to build up a finstock layer over the cavity. The support pillars formed by machining have yield strengths high enough to support UAM of the finstock layer over the cavity. A plurality of finstock layers are built up within the cavity to segment the cavity into a plurality of cavities. UAM of the finstock layers enables the finstock layers to be stacked in a direction normal to a direction of flow through the cavity for efficiently transferring heat through the manifold structure.
