Abstract

Disclosed is a vacuum liquid cooling device used in LED lamps to dissipate heat from the LED lamps. The LED lamp includes an LED lamp and a transparent part for transmitting LED light. The vacuum liquid cooling device includes a shell, a fixing plate, a heat conducting plate and a heat pipe , the shell and the transparent part form a closed inner cavity, the fixed plate is fixed in the inner cavity, the LED lamp is fixed on the surface of the fixed plate close to the transparent part, the heat conduction plate is fixed on the surface of the fixed plate close to the shell, and the heat pipe is a closed double The outer layer of the heat pipe is a vacuum, the inner layer of the heat pipe contains liquid, the first end of the heat pipe is pressed against the heat conduction plate, the second end of the heat pipe is fixed to the shell, the shell, the fixed plate, the heat conduction plate and the heat pipe All are made of thermally conductive material. The vacuum liquid cooling device and the LED lamp have simple structure and high heat dissipation efficiency, and are suitable for high-power lamps with waterproof and dustproof requirements. In addition, an LED lamp is also disclosed.

Description

technical field [0001] The invention relates to the lighting field, in particular to a vacuum liquid cooling device and an LED lamp. Background technique [0002] At present, heat dissipation devices of lighting fixtures on the market usually adopt the method of providing heat dissipation ribs on the surface of the shell to achieve the purpose of heat dissipation. This method dissipates heat unevenly and is inefficient. Especially, when the power of the lamp is high, a large amount of heat energy cannot be dissipated in a short time. [0003] The cooling device of the lighting fixture also adopts the method of setting up a fan inside the lighting fixture to speed up the air flow, so as to improve the heat dissipation efficiency. However, when the lamp has waterproof and dustproof requirements, the air inside the lamp is in a closed state, unable to convect with the air outside the housing, and the fan cannot dissipate heat sufficiently.
