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; one of them uses surface contact to dissipate heat, but the existing surface contact heat pipe radiators have a general heat transfer surface in the evaporation section. It is required to be placed horizontally and lower than the heat dissipation surface of the condensation end. However, in engineering practice, it is often encountered that the heat dissipation surface is a slope with a large inclination to the horizontal plane and the heat pipe can only be in contact with one side of the work object, especially the angle between the slope and the horizontal plane> 45 °, if it is not handled properly, the efficiency is often not high, especially for radiators with non-planar curved surfaces or gravity heat pipes

Abstract

The invention provides a heat pipe radiator with an oblique heat-conducting surface. The heat pipe radiator with the oblique heat-conducting surface is characterized in that the included angle between the axis of an evaporation section of a heat pipe and the horizontal plane ranges from 30 degrees to 90 degrees, and the heat-conducting area is maximized on the premise that the condition is guaranteed; the included angle between the axis of a heat insulating section of the heat pipe and the horizontal plane ranges from 45 degrees to 75 degrees, and the included angle between the axis of a condensation section of the heat pipe and the horizontal plane ranges from 55 degrees to 90 degrees; an outer heat-conducting surface of a heat-conducting block of the evaporation section is kept being in close contact with the cooling surface of a working object, and auxiliary materials with good heat conductivity are smeared on the contact surface; the contact area between the inner heat-conducting surface of the heat-conducting block of the evaporation section and working media in the heat pipe is enlarged by adjusting the included angle between the inner-heat conducting surface of the heat-conducting block and the axis of the evaporation section; the condensation section of the heat pipe is inserted into a hole of a condensation section cooling rib, and condensation section cooling fins are connected with the condensation section cooling rib in a close contact mode; and a condensation section cooling assembly comprises an air cooling assembly or a liquid cooling assembly. The heat pipe radiator with the oblique heat-conducting surface has the beneficial effects that operating efficiency can be improved, energy is saved, and the environment is protected.
