High-power LED (light emitting diode) field lamp heat dissipation device of heat pipe heat conduction type

Abstract

The invention discloses a high-power LED (light emitting diode) field lamp heat dissipation device of heat pipe heat conduction type. A plurality of pre-punching fins are penetrated into two fin plate rows by utilizing a plurality of pre-bent U-shaped heat pipes, and then the two fin plate rows are installed at the back part of a lamp seat symmetrically at two sides by utilizing a clamping plate and a screw. Thus, the heat energy generated by a high-power LED lamp is conducted to a heat pipe through a metal base plate and a lamp base, and then is conducted to fins through the heat pipe, and the heat exchange process of the fins is finished through natural convection. The high-power LED field lamp heat dissipation device has the advantages of large heat dissipation space, high natural heat dissipation efficiency, good uniform temperature, light weight and the like.

AI Technical Summary

Problems solved by technology

The natural convection heat dissipation method of the integration of the lamp holder and the heat dissipation fins is costly, and the arrangement of the heat dissipation fins does not take into account the use of the lamps, often ignoring the balance of convection heat dissipation and heat transfer, thus affecting the heat dissipation effect of the fins The forced heat dissipation method of fins and fans is complex, the reliability is low, and frequent maintenance is required, so it is used less; the heat pipe and loop heat pipe heat dissipation methods have higher heat pipe costs and more complicated processes, but the heat dissipation effect is relatively high. Well, the weight is also light, but the surface of the heat pipe is easy to be oxidized and corroded in the open air, so it needs to be protected, and it is more suitable for application as a venue light
