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. On the working objects that require vertical heat dissipation and the heat pipe can only be in contact with one side, the efficiency is often not high, especially for radiators that use gravity heat pipes

Embodiment 1

[0022] Example 1, Figure 8 is a schematic diagram of embodiment 1, wherein the radiator assembly 32 includes figure 1 or figure 2 The combination of all parts in the circuit board 34 is vertically installed (other components on it are omitted and not shown), the area of ​​the heat conduction surface of the heat conduction block 1 of the evaporation section in the contact direction with the working object ≥ the area of ​​the heat dissipation surface 33 of the heating element, And keep the whole area in close contact, and apply heat-conducting silicone grease on the contact surface; multiple identical circuit boards 34 are vertically parallel installed (only 2 groups are drawn in the figure, and the rest are omitted), and the space between the circuit boards is limited, so The fan 30 is installed in the base 36, blows upward, and the air flow is guided through the channel formed by the fan air duct 31, the relay air duct 10, and the upper air supply duct 13, and is concentrat...

Embodiment 2

[0023] Example 2, Figure 9 is a schematic diagram of embodiment 2, wherein the radiator assembly 32 is composed of figure 1 or figure 2 The combination of all parts in the circuit board 34 is vertically installed (other components on it are omitted and not shown), the area of ​​the heat conduction surface of the heat conduction block 1 of the evaporation section in the contact direction with the working object ≥ the area of ​​the heat dissipation surface 33 of the heating element, And keep the whole area in close contact, and apply thermal conductive silicone grease on the contact surface; multiple identical circuit boards 34 are vertically parallel installed (only 2 groups are drawn in the figure, and the rest are omitted), the space between the circuit boards is limited, but There are also many parts in the base 36, fan 30 cannot be installed, so adopt the mode of drafting from above to carry out air cooling, increase support frame and add vent 37, blower fan 38, air outl...

Embodiment 3

[0024] Example 3, Figure 10 is a schematic diagram of embodiment 3, wherein the radiator assembly 32 includes figure 1 or figure 2 The combination of all parts in the circuit board 34 is vertically installed (other components on it are omitted and not shown), the area of ​​the heat conduction surface of the heat conduction block 1 of the evaporation section in the contact direction with the working object ≥ the area of ​​the heat dissipation surface 33 of the heating element, And keep the whole area in close contact, and apply heat-conducting silicone grease on the contact surface; multiple identical circuit boards 34 are vertically parallel installed (only 2 groups are drawn in the figure, and the rest are omitted), the space between the circuit boards is limited, due to The heat of the heating element is relatively large, and there is space in the base 36 to install the blower fan 30. Therefore, the mode of drafting from the top and the coordinated mode of blasting from t...

Abstract

An air-cooled heat pipe radiator with upright 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 32-83 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; condensation-section radiating fins are in close-contact connection or integral connection with the condensation-section radiating rib; and one or more heat pipes are included, the cross section of each heat pipe, which is perpendicular to the axis of the heat pipe, is round or is shaped like other plane figures. The heat pipe radiator employs an air-cooling mode, is friendly to the environment and has the beneficial effects of improving the operating efficiency, saving materials and protecting the environment.

Description

technical field [0001] The invention relates to the field of radiators, in particular to a heat pipe radiator. Background technique [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 surface heat dissipation and the heat pipe can only be in contact with one side, especially for radiators that use gravity heat pipes. Contents of the invention [0003] The purpose of the present invention is to provide a heat pipe radiator capable of realizing high-efficiency heat dissipation for a work object that requires vertical surface heat dissipation and the heat pipe can only be in contact with one side. [0004] An air-cooled vertical heat-conducting surface heat pipe radiator, including heat pipes, heat-conducting blocks in the evaporation section, additional heat-conducting structures or accessories, cooling co...
