Abstract:
1. A heat dissipation device comprising: a base plate; a fin group arranged on the base plate, the fin group comprising a plurality of fins extending from the base plate, the fins being aligned parallel to and spaced from each other; a first heat pipe comprising a first absorbing section attached on the base plate and a first dissipating section thermally connecting an upper portion of the fin group and aligned parallel to the fins; and a second heat pipe comprising a second absorbing section attached on the base plate and a second dissipating section extending across the fins of the fin group; wherein the base plate defines a pair of V-shaped first grooves along diagonal corners thereof, the V-shaped first grooves are oriented back to back and the first and second absorbing sections are received in the first grooves each of the V-shaped first grooves forming a V-shape approximately parallel to a surface of the base plate; wherein middle parts of the first grooves are arranged adjacent to each other and in a center of the base plate; and wherein the V-shaped first grooves each define an opening of the V-shape facing a corresponding corner of the base plate.
