[0002] When the car headlight assembly is working, the light source in the headlight assembly will generate a lot of heat while emitting light, and the heat will accumulate in the cavity of the headlight assembly, raising the temperature in the cavity of the headlight assembly. Thereby improving the working temperature of each component (for example: light bulb, headlight mask, etc.) Fast, which seriously affects the service life of the parts in the headlight assembly cavity, and the high temperature in the headlight assembly cavity makes it easy to fog in the headlight assembly cavity, which seriously affects the headlight assembly cavity. normal work, which brings great disadvantages to driving safety

The invention provides a heat-dissipating device, comprising a housing, a motor and an outer-rotor centrifugal wheel; the housing is in the shape of a hollow box and includes a bottom wall, a side wall, a top wall and a volute-shaped side shell for forming a volute-shaped centrifugal air passage; the heat-dissipating device is releasably arranged on the exposed back of a base of an automobile headlamp assembly, a through hole in the top wall is communicated with an inner chamber, an air outlet in the side wall is communicated with air, hot air in the inner chamber of the assembly is discharged out for active venting heat-dissipation, the inner chamber of the assembly is cooled, operating temperatures of parts in the inner chamber of the assembly are decreased, the service lives of the parts in the inner chamber of the assembly are extended, mist in the inner chamber of the assembly is decreased and even avoided, and driving safety is improved. The invention also provides an automobile headlamp assembly comprising the heat-dissipating device.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to an automobile headlight assembly and a heat dissipation device thereof. Background technique [0002] When the car headlight assembly is working, the light source in the headlight assembly will generate a lot of heat while emitting light, and the heat will accumulate in the cavity of the headlight assembly, raising the temperature in the cavity of the headlight assembly. Thereby improving the working temperature of each component (for example: light bulb, headlight mask, etc.) Fast, which seriously affects the service life of the parts in the headlight assembly cavity, and the high temperature in the headlight assembly cavity makes it easy to fog in the headlight assembly cavity, which seriously affects the headlight assembly cavity. The normal work of the vehicle will bring greater unfavorable factors to driving safety. [0003] Therefore, how to cool down the inner cavity ...
