LED automobile lamp heat dissipation device

Abstract

The invention discloses an LED automobile lamp heat dissipation device, and relates to the technical field of heat dissipation. The LED automobile lamp heat dissipation device comprises a refrigerator, an exhaust fan, a radiator and a lamp cylinder, wherein one end of an air outlet of the refrigerator is fixedly provided with an air blower through an air pipe, a flow dividing cover is fixed to oneend of the air outlet of the air blower, a set of air outlet pipes are fixed to the peripheral side edge of the flow dividing cover, the peripheral side face of the radiator is fixedly provided witha plurality of heat dissipation sheets, one end of the radiator is fixedly provided with a circular tube, and a plurality of air grooves are formed in one surface of the round tube. According to the LED automobile lamp heat dissipation device, air in the refrigerator is pumped to the radiator through the air blower, the heat dissipation sheets on the surface of the radiator are cooled along the circular tube, and therefore the radiator can be cooled better; a plurality of copper sheets are arranged under the radiator, the heat dissipation sheets are more ideal, and the heat dissipation area isincreased; and meanwhile, the turbine-shaped exhaust fan is arranged underneath, and hot air can be removed in time.

Description

technical field [0001] The invention belongs to the technical field of heat dissipation, and in particular relates to a heat dissipation device for an LED automobile lamp. Background technique [0002] LED car lights refer to the use of LED technology for both interior and exterior light sources of the car for exterior and interior lighting. External lighting involves thermal extremes and EMC issues, along with many complex criteria for unloaded load testing. LED car lights can be widely used to create the interior environment of the car. The service life is 50,000 hours. The structure of LED is strong and not easily affected by vibration, and the light output brightness will not decrease significantly during use. LED car lights are suitable for various lighting applications in automotive electronics, including headlights (high and low beams), fog lights, tail lights, brake lights, turn signals, daytime running lights, pedal lights, instrument lights, license plates Lamps,...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a heat sink for LED car lamps. By pumping the air in the refrigerator to the radiator through the blower, the heat sink on the surface of the radiator is cooled along the circular tube, so that the radiator can be better. Cool down, solve the problem that the heat dissipation effect of the existing LED car light heat sink is not ideal, and the heat sink is too simple to meet the heat dissipation requirements
