Embodiment Construction

[0012] The present invention will be further described below in conjunction with the embodiments with reference to the accompanying drawings.

[0013] refer to Figure 1 to Figure 2 , The heat pipe cooling device of the present invention includes two cooling fin groups 1 and 2, a substrate 4 and a heat pipe 5.

[0014] The substrate 4 has an upper surface 43 and a lower surface 42 . The lower surface 42 defines a horizontal groove 40 . One end of the substrate 4 corresponds to the groove 40 and defines a notch 41 . The notch 41 communicates with the groove 40 .

[0015] The heat pipe 5 is cylindrical, and its inner section along the radial direction is circular. The heat pipe 5 includes an evaporating portion 51 , a condensing portion 52 and a bending portion 53 connecting the evaporating portion 51 and the condensing portion 52 . The outer circular surface of the evaporator 51 has a flat surface 510 that is in direct contact with the heating surface of the heat source. The ...

Abstract

A heat pipe radiation device and making method thereof, which contains substrate, at least one heat pipe and a radiation fins assembly, wherein said heat pipe containing evaporation part and at least condensation part, a channel below substrate for holding the evaporation part which has a plane surface contacted with the heating surface of heat source for quick and effectively absorbing heat, the radiation fins are jointed with condensation part.

Description

【Technical field】 [0001] The invention relates to a heat dissipation device and a manufacturing method thereof, in particular to a heat dissipation device utilizing a heat pipe and a manufacturing method thereof. 【Background technique】 [0002] With the continuous advancement and wide application of large-scale integrated circuit technology, the development of the information industry has advanced by leaps and bounds, and high-frequency and high-speed processors have been continuously introduced. Due to the high-frequency and high-speed operation, the processor generates a lot of heat per unit time. If the heat is not removed in time, the temperature of the processor itself will rise, which will have a great impact on the safety and performance of the system. At present, the problem of heat dissipation has become a problem for every A problem that must be solved when a new generation of high-speed processors is launched. Generally, the industry all installs radiators on chi...
