Problems solved by technology

[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

Embodiment

[0015] For a clearer description, the case of α=30° and β=90° is described as an example. Based on the horizontal placement of the bottom surface of the evaporation chamber 1, that is, the thermal contact surface 3, and the LED light source 4 is pasted on the thermal contact surface 3, the heat pipe radiator 5 and the thermal contact surface 3 are placed at an angle of α=30°, and the rotation axis and the thermal contact surface 3 are determined. The intersection line of the heat pipe radiator 5 and the thermal contact surface 3 is parallel or coincident, the connecting pipe 2 connects the heat pipe radiator 5 and the evaporation chamber 1 according to β=90°, that is, the direction perpendicular to the thermal contact surface 3, and the whole lamp revolves around the rotation axis, Rotate and irradiate within the range of 0°-90°, during the rotation process, the working fluid in the heat pipe system can realize normal gravity circulation to achieve efficient heat dissipation.

Abstract

The invention belongs to the field of LED illumination and heat dissipation and particularly relates to a gravity heat pipe system capable of being rotated and used along with a lamp within the range from 0 degree to 90 degrees. The gravity heat pipe system comprises a heat contact surface of an evaporation chamber, the evaporation chamber, a radiator and a connecting pipe. With the horizontally placed heat contact surface of the evaporation chamber as the benchmark, the heat pipe radiator is located above the evaporation chamber, and the placement angle between the heat pipe radiator and the heat contact surface can range from 0 degree to 80 degrees. The connecting pipe is arranged between the heat pipe radiator and the evaporation chamber. The angle between the connecting pipe and the heat contact surface ranges from 20 degrees to 90 degrees. The connecting pipe is divided into an evaporation pipe body and a backflow pipe body. The heat pipe radiator can be in a single-layer form or a multi-layer form. When the gravity heat pipe system is rotated and used along with the lamp at multiple angles, it can be guaranteed that working media in the gravity heat pipe radiator system can keep unblocked circulation of gas-liquid phase change under the effect of gravity, and the purpose of high-efficiency heat dissipation can be achieved.

Description

technical field [0001] 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°. Background technique [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 heat dissipation effect. Therefore, if you want to meet the multi-angle rotation requirements of the LED floo...
