ABSTRACT:
A heat dissipation device includes a fin assembly, a base, a heat pipe soldered with the base, and a heat spreader sandwiched between the heat pipe and the fin assembly. The fin assembly has a bottom face. The base has a bottom surface and a top surface. The heat pipe comprises an evaporation portion thermally engaging with the top surface of the base plate and a curved portion extending from the evaporation portion and projecting beyond the base plate. The heat spreader has a first face engaging with the bottom face of the fin assembly and a second face thermally engaging with the condensation portion of the heat pipe. The heat spreader has a profile on the bottom face of the fin assembly, which is in compliance with at least a portion of the heat pipe.
