A gravity heat pipe system that can rotate with the lamp in the range of 0°-90°

Abstract

The invention belongs to the field of heat dissipation of LED lighting, and in particular relates to a gravity heat pipe system that can be used by rotating with a lamp in the range of 0°-90°. Including the thermal contact surface of the evaporation chamber, the evaporation chamber, the radiator, and the connecting pipe. Based on the horizontal placement of the thermal contact surface of the evaporation chamber, the heat pipe radiator is located above the evaporation chamber, and the placement angle of the heat pipe radiator and the thermal contact surface can be adjusted. Choose between 0°—80°. There is a connecting pipe between the heat pipe radiator and the evaporation chamber, and the angle between the connecting pipe and the thermal contact surface is selected within the range of 20°-90°. The connecting pipe is divided into evaporation pipe and return pipe, and the heat pipe radiator can be single-layer or multi-layer. With the multi-angle rotation of the lamp, it can ensure that the working medium in the gravity heat pipe radiator system can keep the gas-liquid phase change cycle smooth under the action of gravity, and achieve the purpose of efficient heat dissipation.

Description

Technical field [0001] The invention belongs to the field of LED lighting heat dissipation, and in particular relates to a gravity heat pipe system that can be rotated and used with the lamp in the interval of 0°-90°. Background technique [0002] The heat pipe radiator is the most effective heat dissipation configuration for LED high-power lamps, but the projection lamp in the LED lamp must often change the illumination angle of the lamp according to the needs of the scene, and the heat dissipation principle of the gravity heat pipe radiator is the gravity cycle of the gas-liquid phase change. The heat pipe pipeline loses some gravitational position relationships necessary for gravity circulation as the lamp rotates, so the gravity heat pipe cannot realize the gas-liquid phase change cycle of the working fluid, and thus cannot achieve the heat dissipation effect. Therefore, if you want to meet the multi-angle rotation requirements of LED floodlights, it is necessary to design a ...

[0002] The heat pipe radiator is the most effective heat dissipation configuration for LED high-power lamps, but the floodlights in LED lamps need to change the lighting angle of the lamp frequently according to the needs of the site, and the heat dissipation principle of the gravity heat pipe radiator is the gravity cycle of gas-liquid phase change. The heat pipe pipeline loses some of the gravitational positional relationships necessary for the gravity cycle during the rotation and transformation of the lamp, so the gravity heat pipe cannot realize the gas-liquid phase change cycle of the working fluid, and thus cannot achieve the cooling effect
