Heat sink and method of making same

[0031] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0032] figure 1 It is a perspective view which shows the heat sink which concerns on the preferred 1st Embodiment of this invention.

[0033] Such as figure 1 As shown, the radiator 1 related to the first embodiment includes: enclosing the working fluid and moving from the heat source to the direction of heat dissipation ( figure 1 In the middle is the heat pipe 2 extending a predetermined length from left obliquely upward to right obliquely downward;

[0034] The heat pipe 2 encloses a working fluid such as water or alcohol in a metal tube made of highly heat-dissipating Cu or the like, and transfers heat by utilizing a phase change such as evaporation or condensation of the working fluid. Since the working fluid is sealed under reduced pressure, the phase change is caused by a very small temperature difference, and the heat is transmitted by steam at a...
