Car lamp radiating system and radiating method

Abstract

A car lamp radiating system comprises an internal radiator and an external radiator. The internal radiator comprises a lamp base and an installation column for fixing a light source, and a containing cavity is formed in the lamp base; the external radiator comprises a radiating block and a radiating sheet, a runner is arranged in the radiating block, the containing cavity in the lamp base is communicated with the runner through a first pipe and a second pipe to form a liquid circulation system, and heat conductive liquid is contained in the liquid circulation system; the diameter of the first pipe is larger than the diameter of the second pipe, a first pressure one-way valve for enabling the heat conductive liquid in the containing cavity to flow to the external radiator is arranged at a first liquid outlet of the lamp base, and a second pressure one-way valve for enabling the heat conductive liquid in the external radiator to flow to the containing cavity in the lamp base is arranged at the first liquid inlet of the lamp base. The radiating system is combined with the light source lamp base, a water pump is omitted, the size of the overall radiating system is smaller, and the car lamp radiating system is suitable for installation of a traditional lamp base assembly.

Description

technical field [0001] The invention relates to a heat dissipation system, in particular to a vehicle light heat dissipation system and a heat dissipation method. Background technique [0002] Existing car lights generally dissipate heat through radiators and fans, and the heat dissipation efficiency of air-cooled heat dissipation is low. For high-power car lights, air-cooled heat dissipation cannot meet the heat dissipation needs of car lights, so it often leads to high operating temperature of car lights. too high. The long-term high-temperature working state of the car lights will seriously affect the service life of the LED light source of the car lights. Therefore, it is necessary to find a more effective heat dissipation system to dissipate heat from the car lights. The heat dissipation efficiency of water cooling is higher than that of air cooling. There are also a few lights on the market that use water cooling systems. The existing water cooling systems mainly incl...

Problems solved by technology

Due to the large size of the water pump and the limited space in the existing car light assembly, it is difficult to combine the water pump with the lamp holder and install it in the car light assembly. Therefore, it is necessary to modify the traditional car light assembly to use the water cooling system. installation, which undoubtedly increases the cost of the lamp
