Car lamp heat dissipation system and car lamp

Abstract

The utility model provides a car lamp heat dissipation system and a car lamp, the car lamp heat dissipation system comprises a mounting plate and a heat dissipation assembly, and the mounting plate is provided with a first heat conduction hole; the heat dissipation assembly comprises a heat dissipation copper pipe and a heat conduction gasket. The heat dissipation copper pipe is arranged on one side of the mounting plate, and the heat conduction gasket is arranged on the other side of the mounting plate; the heat-conducting gasket is provided with second heat-conducting holes corresponding to the first heat-conducting holes; wherein the size of the second heat conduction hole is smaller than that of the first heat conduction hole, and the heat conduction gasket is in contact with the heat dissipation copper pipe corresponding to the first heat conduction hole. According to the scheme, the heat conduction gaskets can directly make contact with the heat dissipation copper pipes corresponding to the first heat conduction holes, heat, absorbed by the heat conduction gaskets, on the circuit board is conducted out through the heat dissipation copper pipes, and the heat of the circuit board is effectively reduced. According to the scheme, high heat energy transmitted to the circuit board by the light source module of the automobile lamp can be effectively led out, the probability of damage to components on the circuit board is reduced, and the service life of the automobile lamp is prolonged.
