Lamp and liquid-cooling radiator thereof

Abstract

The invention provides a liquid-cooling radiator of a lamp. The liquid-cooling radiator comprises a lamp shell having an opening, a light source, a water-cooling block, a heat exchanger, a water tank, a water pump, and a water pipe. The inside of the lamp shell is divided into a closed first chamber and a second chamber having an opening, by a partition. The light source is disposed in the second chamber and fitted to the partition. The water-cooling block is disposed in the first chamber and fitted to the partition. The heat exchanger and the water tank are both fitted to the inner wall of the first chamber. The water pump is mounted on the water tank. The water pipe penetrates the water-cooling block and the heat exchanger; two ends of the water pipe are connected to the water tank. The heat exchanger is provided with radiating fins provided with a fan. The partition and the lamp shell are integrated; the first chamber is provided with a rear cover; the heat exchanger is mounted on the rear cover. The liquid-cooling radiator is high in radiating efficiency and easy to demount. The invention further provides the lamp comprising a reflector, a light-permeable plate and the radiator; the lamp is high in radiating performance; a high-power light source can be used; excessively high heat is prevented from burning out the light source or the circuit board and electronic components in the lamp.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of lamps, in particular to a liquid cooling heat dissipation device for a lamp and a lamp using the heat dissipation device. Background technique [0002] Many occasions require the use of lamps equipped with high-power light sources. High-power light sources generate a lot of heat, and circuit boards and electronic components are usually installed in such lamps. The board or electronic components are burned out, so the heat dissipation capability inside the lamp is particularly important. In the prior art, most lamps only rely on the lamp housing to transfer heat to the lower temperature part. This way of heat dissipation is slow, and the heat cannot be transferred out in time, which may easily cause the light source, circuit board or electronic components to burn out, and this This method will cause uneven heat distribution of the lamp housing, and long-term local thermal expansion and...

Problems solved by technology

In the prior art, most lamps only rely on the lamp housing to transfer heat to the lower temperature part. This way of heat dissipation is slow, and the heat cannot be transferred out in time, which may easily cause the light source, circuit board or electronic components to burn out, and this This method will cause uneven heat distribution of the lamp housing, and long-term local thermal expansion and contraction may easily lead to cracking of the lamp housing

Although some lamps are equipped with heat sinks, these heat sinks have complex structures and many parts, which are not easy to install and disassemble.
