Cooling device with ringed fins

Abstract

A cooling device includes a heat-conducting base, two fin sets, and a heat pipe. The two fin sets are respectively constructed by a metallic stripe that is periodically folded and is arranged as a ring type. The heat pipe has a heated section that is thermally connected to the heat-conducting base, and a condensing section that is extended from the heat-conducting base is further formed as a flat shape, on which two oppositely flat faces are formed. The two flat faces of the condensing section of the heat pipe are respectively contacted closely with the two fin sets by being sandwiched therein. In such case, the contact area between the condensing section of heat pipe and the fin sets is enhanced, thus that the heat-conducting effect is promoted significantly.
