[0003] Traditional automotive headlight heat sinks mostly use air cooling, which has the problem of low heat dissipation efficiency. Air cooling systems rely on air convection for heat dissipation, and are prone to thermal saturation in high-temperature environments or during prolonged lighting, causing the lamp body temperature to rise continuously, accelerating the aging of the light source chip, and shortening the lamp's lifespan.

[0004] Therefore, there is an urgent need for a new type of vehicle headlight radiator to solve the problems of low efficiency and poor high-temperature stability of existing air-cooled systems, and to ensure driving safety. Utility Model Content

[0021] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a vehicle headlight radiator, including a lamp body 1, a radiator assembly 2, and a micro water pump 14. The radiator assembly 2 includes a lamp holder 3, which is made of a metal material with excellent thermal conductivity (such as aluminum alloy). Its main function is to fix the lamp body 1 and efficiently transfer the heat generated by the lamp body 1. An installation groove 4 is opened on the upper surface of the lamp holder 3, and the lamp body 1 is installed in the installation groove 4. Thermally conductive silicone is filled between the lamp holder 3 and the lamp body 1 to ensure close contact between the lamp body 1 and the lamp holder 3, reduce thermal resistance, and improve heat transfer efficiency.

[0023] The lower surface of the lamp holder 3 is fixedly connected to the cold head 5 via a threaded connection. The gap between the lamp holder 3 and the cold head 5 is filled with thermally conductive silicone. The internal structure of the cold head 5 is designed as a multi-channel diversion structure, which includes multiple parallel diversion channels to ensure uniform distribution of coolant and increase the contact area between the coolant and the inner wall of the cold head 5, thereby improving heat exchange efficiency. An outlet 6 and an inlet 7 are respectively provided on both sides of the cold head 5.

[0024] The lower surface of the cold block 5 is bolted to the radiator 8. An inlet tank 9 and an outlet tank 10 are respectively installed on both sides of the radiator 8. A heat dissipation pipe 11 is located in the middle of the radiator 8. The heat dissipation pipe 11 has an olive-shaped cross-section, increasing the heat dissipation area. Numerous heat dissipation fins 12 are evenly distributed on the heat dissipation pipe 11. The heat dissipation fins 12 are made of thin sheet metal and are either welded perpendicularly to the heat dissipation pipe 11 or integrally formed to further increase the heat dissipation area. The radiator 8 is in close contact with the cooling fan 13, which is installed on the outside of the radiator 8 and uses a blowing design. When the fan rotates, it blows air towards the radiator 8, accelerating airflow on the surface of the radiator 8 and improving heat dissipation.

[0025] The miniature water pump 14 is located on one side of the radiator assembly 2. The miniature water pump 14 is a mature existing technology and can be a Dongyuan Xinrui SC-P60 water-cooled circulating pump with a built-in brushless DC motor driven impeller pump. The inlet of the miniature water pump 14 is connected to the outlet 6 through a pipe, the outlet of the miniature water pump 14 is connected to the inlet tank 9 through a pipe, and the outlet tank 10 is connected to the inlet 7 through a pipe.

[0026] Workflow:

[0027] When the headlight is working, the heat generated by the lamp body 1 is quickly transferred to the lamp holder 3 through the thermally conductive silicone filling the space between the lamp body 1 and the lamp holder 3. The lamp holder 3 conducts the heat to the cold head 5, and the coolant enters from the inlet 7 of the cold head 5. Utilizing its internal multi-channel diversion structure, the coolant is evenly distributed and fully absorbs the heat transferred from the cold head 5 before flowing out from the outlet 6. The micro water pump 14 draws in the heated coolant, pressurizes it, and delivers it to the inlet tank 9 of the radiator 8. The coolant flows within the olive-shaped heat dissipation pipes 11 of the radiator 8, conducting heat to the surrounding air through the pipe walls and heat sink 12. The cooling fan 13 adopts a blowing design to accelerate airflow and remove heat from the surface of the heat sink 12, achieving liquid-gas heat exchange. The cooled coolant flows out from the outlet tank 10 of the radiator 8 and returns to the inlet 7 of the cold head 5 through pipes. The micro water pump 14 continuously drives the coolant to circulate in a closed loop, constantly dissipating the heat generated by the lamp body 1 and maintaining the headlight at a suitable operating temperature.
