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.
