Heat dissipation device with a heat pipe

A heat dissipation device for an electronic component, comprising:

• a fin assembly having a bottom face;
• a heat spreader attached to the bottom face of the fin assembly;
• a heat pipe having at least a portion being attached to the heat spreader;
• and
• a base plate having a first face attached to an evaporation portion of the heat pipe and an opposite second face adapted for contacting with the electronic component;
• wherein the heat spreader has a profile on the bottom face of the fin assembly which is substantially the same as that of the heat pipe in whole.

A heat dissipation device comprising:

• a fin assembly comprising a plurality of fins having a bottom face at a bottom thereof;
• a base plate being smaller than the bottom face of the fin assembly, having a first surface adapted for contacting with a heat-generating electronic component and a second surface opposite to the first surface;
• a heat pipe comprising an evaporation portion thermally engaging with the second surface of the base plate, and a curved portion extending from the evaporation portion and projecting beyond the base plate;
• a heat spreader being curved and comprising a curved section thereof having a profile similar to the curved portion of the heat pipe, the curved section having a first face engaging with the bottom face of the fin assembly and a second face thermally engaging with the curved portion of the heat pipe;
• an additional heat pipe similar to the heat pipe, wherein the additional heat pipe is so oriented that it opens to a direction opposite to that of the heat pipe;
• and
• an additional heat spreader matching the additional heat pipe, wherein the additional heat spreader is sandwiched between the fin assembly and the additional heat pipe and thermally contacts the additional heat pipe;
• wherein the heat spreader defines a groove at the second face thereof, the groove thermally receiving the curved portion of the heat pipe therein;
• wherein the curved portion of the heat pipe is L-shaped, the curved section of the heat spreader is L-shaped corresponding to the curved portion of the heat pipe;
• and
• wherein the heat pipe is U-shaped, the curved portion of the heat pipe comprises a condensation portion parallel to the evaporating portion of the heat pipe and a connecting section connecting the evaporation portion and the condensation portion.
