Description

Technical Field

[0001] The utility model relates to the technical field of automobile headlights, in particular to a heat dissipation structure of an automobile headlight with multiple modules for cooling. Background Art

[0002] A car is a means of transportation. Its headlights illuminate the road at night and signal various vehicle movements. To provide good illumination at night or in low-visibility conditions, headlights require high power to maintain brightness, but this generates a significant amount of heat. High-power headlights heat up rapidly after prolonged operation, and spatial limitations hinder heat dissipation. Headlights are installed in specific locations on the vehicle, creating a relatively narrow interior. This limited space makes it easy for heat to accumulate and difficult to dissipate quickly. This also limits the size and shape of heat dissipation components. However, existing headlight structures have low heat dissipation efficiency during use and cannot meet the heat dissipation requirements of high-power headlights. In high-temperature environments or after prolonged use, the internal temperature of the headlights remains excessively high, impacting their service life and performance. Utility Model Content

A heat dissipation cavity is set between the shell 10 and the lamp shell 20, and the fan 401 is set inside the heat dissipation cavity of the shell 10 and the lamp shell 20. The heat conducting rod 30 is set around the surface of the lamp shell 20, and the end of the lamp shell 20 is set corresponding to the position of the bulb 203. The end of the heat conducting rod 30 passes through the lamp shell 20 and the surface of the shell 10 and is connected to the heat sink 301. The heat sink 301 is set around the outside of the shell 10.
