Embodiment 1

[0020] The structure of a radiator in the embodiment of the present invention is as follows: figure 1 As shown, its cross-section is shown as figure 2 shown. The heat sink of this embodiment includes an array heat pipe 1 and special-shaped fins 2 , wherein the array heat pipe 1 and the special-shaped fins 2 are integrally formed by extruding aluminum alloy processing equipment without gaps in between.

[0021] In this embodiment, the material of the array heat pipe 1 is aluminum alloy, including a plurality of independent heat pipes evenly arranged, the cavity inside the heat pipe is filled with a phase change working medium, and the cross section of the cavity inside the heat pipe is circular. Both ends of the array heat pipe 1 are welded and sealed after being vacuumed.

[0022] In this embodiment, the special-shaped fins 2 are I-shaped fins, which are arranged on both sides of the array heat pipe 1 .

[0023] In this embodiment, the I-shaped fin can also be arranged on ...

Embodiment 2

[0025] A cross-section of a heat sink according to an embodiment of the present invention is as follows: Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the special-shaped fins of this embodiment are angular fins, and the angular fins are arranged on one side of the heat pipe array. The angular fins in this embodiment can also be arranged on both sides of the heat pipe array.

Embodiment 3

[0027] A cross-section of a heat sink according to an embodiment of the present invention is as follows: Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the special-shaped fins of this embodiment are S-shaped fins, and the S-shaped fins are arranged on one side of the heat pipe array. The S-shaped fins in this embodiment can also be arranged on both sides of the heat pipe array.

Abstract

Disclosed is a radiator. The radiator comprises array heat pipes and abnormally-shaped fins, wherein the abnormally-shaped fins can improve the chimney effect, the array heat pipes and abnormally-shaped fins are integrally formed, and no gaps exist between the array heat pipes and the abnormally-shaped fins. Due to the facts that the radiator comprises the abnormally-shaped fins, and the abnormally-shaped fins and the array heat pipes are integrally formed, the area of the fins is increased, the chimney effect is improved, the problem that heat conduction of the heat pipes is quick, but the heat dissipation efficiency of the heat pipes is low is solved, and the heat dissipation effect is improved. Meanwhile, the number of the working procedures is reduced, the cost is saved, and an array heat pipe radiator can be safer, more reliable and more environmentally friendly. In addition, the radiator expands the application fields of aviation, aerospace, computers, electric appliance components, electronic equipment, civil radiators and the like, and has the quite high social value and the quite high economic benefit.

Description

technical field [0001] The invention relates to the technical field of radiators, in particular to a heat pipe radiator with special-shaped fins. Background technique [0002] At present, the heat pipe heat dissipation technology is applied to the field of heat dissipation of aerospace, computer, electrical components, and electronic equipment, and has achieved good results. The advent of the heat pipe has brought about new developments in the cooling system of power electronic devices. The heat pipe is an artificial component with excellent heat transfer. The commonly used heat pipe is composed of three parts: the main body is a closed metal tube, and there is a small amount of working medium and capillary structure inside. The air and other sundries in the tube must be excluded. The heat pipe utilizes three physical principles when working: (1) in a vacuum state, the boiling point of the liquid decreases; (2) the latent heat of vaporization of the same substance is much h...
