Three kinds of thermal technologies in car LED light
The heat of LED car lights mainly comes from the heat generated by the LED light source. Almost all the electricity consumed by the LED light source can be converted into light and heat. The current LED car lights on the market have the following three main thermal technologies:
Aluminum heat sink (first generation)
Generally, LED car lights use the technology of metal aluminum body to dissipate heat. A layer of metal copper heat conduction plate is designed inside the metal aluminum body, and the heat derived from the LED car lamp is conducted to the metal copper heat conduction plate and then transferred to the bottom sun flower pattern aluminum extrusion heat sink and all corners of the metal aluminum body, and the heat can be quickly diffused.
Heat pipe cooling (second generation)
The superconducting heat pipe is composed of copper pipe, capillary structure and working fluid. One end of the heat pipe is the evaporation zone, the other end is the condensation zone, and the middle part is the adiabatic section.
The most commonly used copper/water heat pipes at room temperature are copper/methanol heat pipes, copper/acetone heat pipes, aluminum/ammonia heat pipes and aluminum/acetone heat pipes at low temperatures. The company can provide copper/water heat pipes, copper/methanol heat pipes and copper/acetone heat pipes.
By inserting a hollow heat-dissipating metal plate inside the LED lamp body, which contains liquid, when the lamp heats up, the liquid in the heat-dissipating plate will absorb heat and become gas, and spread to other areas of the heat sink and the metal aluminum back cover. To achieve the effect of heat exchange and average emission.
Vapor chamber thermal conductivity circulation system (third generation)
The material of the vapor chamber is mainly oxygen-free copper C1020, and the working fluid can be water, methanol and acetone. The capillary structure can be copper powder sintering or copper wire mesh sintering. The shape of the superconducting soaking plate can be flat or three-dimensional. The basic dimensions and structural graphics are as follows:
The internal heat dissipation of the LED car lights mainly uses a vapor chamber and a copper plate to dissipate heat. The vapor chamber heat sink distributes the center temperature of the LED car lamp heat to a large area for uniform heat dissipation and rapid conduction.
