Heat dissipation assembly and vehicle lamp heat dissipation system

Abstract

The utility model provides a heat dissipation assembly and a vehicle lamp heat dissipation system. The heat dissipation assembly comprises a plurality of heat dissipation fins, a heat dissipation fan and a fan housing, and the multiple heat dissipation fins are parallel to one another and arranged at intervals; the heat dissipation fan is located beside the heat dissipation fins, is provided with an air inlet and an air outlet and is used for providing heat dissipation airflow for gaps between the adjacent heat dissipation fins; the fan housing is arranged on the periphery of the cooling fan in a surrounding mode, and the fan housing is provided with at least two flow guide parts corresponding to an air outlet of the cooling fan so that cooling airflow can be converged between the at least two flow guide parts. The fan housing is arranged on the periphery of the heat dissipation fan, and the at least two flow guide parts are arranged on the fan housing corresponding to the air outlet of the heat dissipation fan, so that heat dissipation airflow generated by the fan can be gathered between the flow guide parts, the heat dissipation airflow loss is reduced, more heat dissipation airflow acts on gaps among the heat dissipation fins, and the heat dissipation efficiency is improved. And the heat dissipation efficiency of the heat dissipation assembly is improved. Therefore, the service life of the automobile lamp can be prolonged.
