High efficiency heat dissipation phase change LED lamp thermal column and heat dissipation structure thereof

Abstract

The invention discloses a high efficiency heat dissipation phase change LED lamp thermal column and a heat dissipation structure thereof. The thermal column comprises a water absorption layer, the water absorption layer is coated with a carbon fiber layer, and the carbon fiber layer is coated with a graphene layer. The heat dissipation structure comprises a heat dissipation cavity, phase changing liquid is filled inside the heat dissipation cavity, thermal columns are arranged inside the heat dissipation cavity, and the thermal columns are in contact with phase changing liquid. The phase changing liquid absorbed into the water absorption layer, because of the capillary force of the absorption layer, can be guaranteed to be absorbed into the water absorption layer even if the rotations are at any of the angles. Afterwards, the water absorption layer is coated with a layer of carbon fiber, the carbon fiber has very good water absorption ability and very good heat conductivity, can absorb water while conducting heat, and the phase change liquid in the water absorption layer is vaporized, thereby the heat conductivity effect and the heat dissipation effect are achieved, and the dissipation effect is effectively increased by 30%-80%.

Description

technical field [0001] The invention relates to a lamp, and more specifically relates to a heat dissipation structure of a phase-change LED lamp with high heat dissipation. Background technique [0002] In the prior art, the Chinese patent application number 201610034907.9 discloses a high-efficiency heat dissipation LED floodlight, which includes a housing, an LED lamp is arranged inside the housing, and a radiator is also arranged inside the housing. The LED lamp is bonded to the heat sink, and the heat sink is provided with an accommodation chamber filled with a phase change liquid, and heat pipes are arranged at both ends of the heat sink accommodation chamber. When used at an incline, the phase change fluid will leave the position of the heat sink attached to the LED light. At this time, during the use of the LED light, the LED light emits heat. Since the heat pipe is installed on the heat sink, the heat pipe plays an indirect heat transfer function. The effect of heat...

Problems solved by technology

[0003] However, when a large tilt occurs, some heat pipes may not be able to touch the phase change fluid, and it is impossible to achieve a better heat dissipation effect after all-round adjustment of 360 degrees
