Problems solved by technology

[0002] Heat pipes using the principle of phase change and heat conduction are widely used in radiator technology due to their high heat transfer efficiency. It is often not efficient on work objects that require vertical heat dissipation and the heat pipe can only be in contact with one side, especially for radiators with non-planar curved surfaces or gravity heat pipes

Embodiment 1

[0031] Example 1, Figure 13 is a schematic diagram of embodiment 1, Figure 14 Yes Figure 13 The C-C sectional view (not a sectional view) shows the good cooperation of the section of the heat pipe assembly and the section of the heat dissipation surface of the container; the work task to be completed is; the inside of the cylindrical container 61 needs to dissipate heat, and the heat pipe can not be installed on the container cover 62 to dissipate heat The bottom of the container is also inappropriate, and only the vertical sides of the container can be used for heat dissipation; therefore, a heat pipe radiator with a conformal vertical heat transfer surface is used. In the figure, the radiator assembly 64 includes figure 1 or figure 2 The combination of all parts except the heat pipe assembly, the heat pipe assembly adopts Figure 5 As shown in the heat pipe assembly of the single heat pipe conformal vertical heat transfer surface heat pipe radiator, the heat dissipati...

Embodiment 2

[0032] Embodiment 2, put Figure 13 The fan 67 is removed, which is the schematic diagram of Embodiment 2. For occasions where the heat dissipation requirements are not too high, a conformal vertical heat transfer surface heat pipe radiator can be used, and the heat dissipation fins can be cooled by natural air to achieve a certain power. The effect of cooling with a fan; the main air duct 66, the relay air duct 10, the upper air supply duct 13, and the grille holes on the bottom cover 68 should all have and be optimized; it can dissipate heat and cool down without consuming energy, so as to save energy Effect.

Embodiment 3

[0033] Example 3, Figure 15 It is a schematic diagram of embodiment 3, and the drawing is a sectional view, and the sectional plane is a vertical plane passing through the centerline of the heat pipe and parallel to the page, Figure 16 Yes Figure 15 D-D partial cross-sectional view of ; Figure 15The equipment cabinet 70 in the work is in relatively bad environment, so shell 79 adopts fully enclosed structure to strengthen protection; , the heat dissipation surface is a vertical curved surface, so a heat pipe radiator with a conformal vertical heat conduction surface is adopted, and the area of ​​the heat conduction surface of the heat conduction block 85 of the evaporation section of the heat pipe 80 in the contact direction with the working object ≥ the area of ​​the heat dissipation surface of the heating element 76, and keep The whole area is in close contact, and the contact surface is coated with heat-conducting silicone grease. The condensation section of the heat ...

Abstract

A heat pipe radiator with conformal vertical heat-conducting surfaces is characterized in that the included angle between a normal line of the heat-conducting surface, contacted with a working medium in a heat pipe, of an evaporation-section heat-conducting block and the axis of the heat pipe is 35-82 degrees; the heat-conducting surface, contacted with a work object, of the evaporation-section heat-conducting block remains in close contact with the a radiating surface of the work object, and the contacted surfaces are coated with an auxiliary material with a good heat-conducting property; a condensation section of the heat pipe is inserted into a hole of a condensation-section radiating rib and maintains favorable heat contact; a condensation-section radiating fin is in close-contact connection or integral connection with the condensation-section radiating rib; and the term 'conformal' means that the heat-conducting surface, contacted with the work object, of the evaporation-section heat-conducting block is adapted to the radiating surface of the work object in shape, and includes single-sided conformal or double-sided conformal. The heat pipe radiator has the beneficial effects of improving the operating efficiency, saving energy and protecting the environment.
