Description
Technical Field
[0001] The utility model belongs to the technical field of heat dissipation devices, and particularly relates to an automobile headlight radiator. Background Technique
[0002] Automobile headlights are important safety accessories for vehicles. They not only provide illumination at night or in low visibility conditions but also communicate with other road users through various light signals. The types of automobile headlights include headlamps, tail lights, turn signals, fog lights, daytime running lights, etc. Each type of lamp has its specific function and usage scenario. The heat dissipation of automobile headlights is a crucial design aspect, especially for LED headlights. Since LEDs generate a large amount of heat during operation and their performance is significantly affected by temperature, good heat dissipation design is the key to ensuring the brightness, efficiency, and lifespan of the headlights.
[0003] Heat dissipation technologies are mainly divided into two methods: passive heat dissipation and active heat dissipation. Passive heat dissipation mainly relies on the heat conduction performance of heat sinks and materials to dissipate heat. The LED circuit board is usually closely connected to an aluminum heat sink with high thermal conductivity, and the heat is dissipated into the air through large-area contact. To improve the heat dissipation efficiency, the design of the heat sink considers the fin shape and area, as well as the filling of the heat conduction medium. Active heat dissipation technologies include using fans, liquid cooling, heat pipes, etc. to forcibly dissipate heat. Fan cooling is the most common active heat dissipation method, where a high-speed rotating fan circulates air inside the lamp body to effectively carry away the heat. Heat pipe cooling uses the evaporation and condensation of liquid in a vacuum tube to transfer heat. However, due to the complex structure of the heat pipe cooling method, it is less used in headlight heat dissipation. Existing heat dissipation devices mostly adopt air-cooled heat dissipation methods according to actual needs. During the use of some existing air-cooled headlight heat dissipation devices, because their internal structures are closed, after long-term use, due to thermal expansion and contraction, the internal structures will gradually deform, thus affecting normal use.
