The heat dissipation problem of LED high bay light
The heat dissipation problem of LED high bay light is a serious problem. The solution to it is mainly through a technology, so how is it solved?
At present, the best heat dissipation method for LED high bay light is the composite phase change cooling technology of micro-grooves. Small size and light weight. Good thermal conductivity and heat dissipation. The principle is to use the micro-groove structure to pull the liquid heat transfer medium into a very thin liquid film. The heat of the LED high bay light is transferred to the very thin liquid film, and the liquid film vaporizes to take away huge heat, and the vapor is in the airtight space inside the radiator. It diffuses into the fins of the radiator in contact with the air, and after cooling, it becomes a liquid heat transfer medium and returns to its original position for recirculation. The heat transfer is carried out by using the high-strength composite phase change enhanced heat transfer mechanism of the heat sink with the micro-scale groove group structure.
The liquid working medium with the latent heat of vaporization flows along the micro-grooves under the capillary pressure gradient formed by the micro-groove group itself, and at the same time, it forms high-strength micro-scales in the groove of the thin liquid film evaporation of the extended meniscus and the nucleate boiling of the thick liquid film. The composite phase transition enhances the heat transfer process and takes away huge heat, and its theoretical maximum heat flux density can reach the order of W/. It has the advantages of strong heat extraction ability, excellent temperature control ability, centralized heat treatment mode, long-distance heat transportation and heat dissipation, no power consumption cooling, high efficiency and energy saving, material saving, high efficiency waste heat utilization, high reliability, and low processing cost. Reducing the volume and weight of the LED high bay light can also solve the problem of heat dissipation, which can reduce the occurrence of heat dissipation problems at the root.
