LED lamp radiator for vehicle

Abstract

The invention discloses an LED lamp radiator for a vehicle and relates to the technical field of LED lamps. The LED lamp radiator for the vehicle comprises a lamp holder and a cooling cylinder, wherein the lamp holder is of a long plate shape, the inner side surfaces of the lamp holder are provided with a radiating substrate which is composed of a long copper plate and radiating fins, the thickness of the long plate is 1.1-1.3mm, the radiating fins are arranged on the long plate at equal intervals, the long plate is connected with the inner side surfaces of the lamp holder, the thickness of each radiating fin is 1.6-2.2mm, and cooling pipes penetrate the cooling fins back and force and are connected with the cooling cylinder. The radiating fins are thin in thickness and large in area so that the thermal conductivity is improved. The contacting area with the air is large so that rapid air cooling can be realized. Conversion current is formed by the cooling liquid which is due to the temperature difference and rapid flow so that fast cooling of the radiating fins can be realized and the radiating speed is improved. The cooling cylinder is used for storing and backflowing the cooling liquid and providing power to drive the flow of the cooling liquid so that the flowing speed of the cooling liquid can be fastened.

Description

technical field [0001] The invention belongs to the technical field of LED lamps, in particular to a heat sink for LED lamps for vehicles. Background technique [0002] LED lamps have the advantages of small size, low power consumption, online programming and flexibility, and are gradually accepted by consumers. There are more and more applications in automotive lights. Only when multiple The light intensity generated by the LED lamps working at the same time can meet the requirements of the car lights, but multiple LED lamps work at the same time and the adjacent distance is small, so that the heat generated is relatively large. If the heat dissipation is not timely, it will directly affect the normal operation of the LED lamps. , which puts forward higher requirements on the heat dissipation performance of LED lamps. For example, the application number 201310114336.6 discloses a grease heat dissipation LED lamp, which includes an LED lamp and a heat dissipation cover. The...
