Problems solved by technology

At present, many heat pipe radiators, due to the imperfect multi-level structure design, it is difficult to ensure the smooth gas-liquid phase change gravity circulation of the heat pipe in the inclined installation of the heat pipe radiator of the lamp. Radiator", although this kind of gravity heat pipe radiator with branch structure can effectively extend a large heat dissipation area on the narrow evaporation chamber, but when the lamp is tilted, the evaporation pipeline will have a downward bend in the branch structure At the same time, the return pipeline will have an upward bend in the branch structure, resulting in the loss of gravity, poor gas-liquid circulation, and poor heat dissipation

Embodiment Construction

[0012] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings, but this is not intended to limit the present invention. The scope of protection of the present invention is subject to the content recorded in the claims. Without departing from the protection scope of the present invention.

[0013] The overall structure of this embodiment is as follows figure 1 As shown, the rotation axis 2 is first determined on the horizontally placed evaporation chamber 1, and then the evaporation port 3 and the return port 4 are set on both sides of the rotation axis, and the evaporation pipeline 6 is drawn from the evaporation port 3 and circles upwards to the top. An evaporation horizontal tube 8 is formed. The evaporation horizontal tube is roughly parallel to the rotation axis 2. The evaporation pipelines are all in the same plane. The highest end of the evaporation horizontal tube has a connecting tube 9, which extends in ...

Abstract

The invention belongs to the technical field of heat pipe heat dissipation and particularly provides a gravity heat pipe radiator which can be used in radiation rotation of an LED projection lamp. An evaporation pipeline and a return pipeline adopt a roundabout ascending coiling mode and are located in different parallel layers respectively, the heat dissipation area of a heat pipe can be increased to the maximum degree, and heat dissipation efficiency is improved. Functions of an evaporation opening, a return opening, the evaporation pipeline and the return pipeline can be exchanged in the clockwise and counterclockwise rotating process, the installation requirement for multi-angle irradiation of the lamp can be met to the maximum degree, and meanwhile gravity circulation smoothness of gas-liquid phase change of the heat pipe is ensured.

Description

technical field [0001] The invention belongs to the technical field of heat pipe heat dissipation, and in particular refers to a gravity heat pipe radiator which can be used in downward rotation of LED floodlights. Background technique [0002] It is one of the best technical solutions for high-power LED lamps to use heat pipes to dissipate heat. Due to the limitation of the structure of the lamp, how to make the heat pipe obtain the largest heat dissipation area in a limited space, and at the same time make the heat pipe radiator of the lamp maintain a smooth gas-liquid phase change gravity circulation at various inclination angles. This is the design of the heat pipe radiator key. At present, many heat pipe radiators, due to the imperfect multi-level structure design, it is difficult to ensure the smooth gas-liquid phase change gravity circulation of the heat pipe in the inclined installation of the heat pipe radiator of the lamp. Radiator", although this kind of gravity...
