[0002] A headlight reflector is a bowl-shaped optical reflector typically installed inside a car headlight. Its main function is to collect and reflect the light emitted by the headlight bulb to enhance the brightness and illumination range of the light. When headlights are used for extended periods, regardless of the type of bulb, the longer the headlights are used, the more heat accumulates, and the higher the temperature of the reflector becomes. This not only affects the light reflection efficiency but also allows the heat to be conducted to the bulb, thus affecting the bulb's performance.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] Please see Figures 1 to 5 This utility model provides a heat dissipation structure for a vehicle headlight reflector. The heat dissipation structure includes: a headlight body 1, which houses and protects various internal heat dissipation and lighting components; the reflector is made of a material with good heat resistance and mechanical strength; a cavity 12 is provided in the middle of the headlight body 1; a water-cooling device body 4 is fixedly connected to the rear side of the cavity 12; the water-cooling device body 4 has water-cooling pipes inside, through which coolant circulates, efficiently absorbing heat; and a heat sink housing 5 is fixedly connected to the front side of the cavity 12. The heat sink housing 5 is made of a material with high thermal conductivity. Made of metal, it has a large heat dissipation surface area. Fans 7 are fixedly connected to both sides of the front of the main body 4 of the water-cooling device. Filter plates are installed on the surface of the fans 7, and the mesh size of the filter plates is carefully designed to effectively prevent dust and debris from entering the fan 7. A water pipe 6 is fixedly connected to the water inlet of the main body 4 of the water-cooling device, and the other end of the water pipe 6 is fixedly connected to the water outlet of the water tank 3. The water tank 3 is fixedly connected to the right rear side of the headlight body 1. A water inlet 13 is located on the upper front side of the water tank 3. A first cooling fan 9 is located in the middle of the lower part of the heat sink housing 5, and a second cooling fan 9 is located in the middle of the upper part of the heat sink housing 5. The cooling fan 10, the second cooling fan 10, and the first cooling fan 9 work together to form a vertically connected airflow channel, enhancing the overall heat dissipation efficiency of the cooling fin housing 5. Reflector bowl bodies 8 are fixedly connected to the upper sides of both sides of the cooling fin housing 5. Lamp housings 11 are fixedly connected to the inside of the reflector bowl bodies 8 through the cooling fin housing 5. When the headlight is working, the lamp housing 11 emits light and generates heat. Since the lamp housing 11 is connected to the reflector bowl bodies 8 through the cooling fin housing 5, the heat is first transferred to the cooling fin housing 5 through thermal conduction. The cooling fin housing 5 has a large heat dissipation surface area, which allows the heat to be dissipated more effectively. The first cooling fan 9 and the second cooling fan 10 in the middle above work together to form a vertically connected cooling airflow channel. At this time, the fan 7 works to drive the airflow. The water-cooled air passes through the cooling airflow channel, which accelerates the airflow speed on the surface of the cooling fin housing 5, so that the heat on the cooling fin housing 5 can be carried away more quickly. At the same time, the heat will be conducted to the main body of the water cooling device 4. The coolant flows in the pipe, absorbs heat and rises in temperature, realizing heat exchange for the cooling fins, thereby indirectly cooling the reflector bowl body 8 and achieving effective heat dissipation for the headlight reflector bowl.

[0024] In the embodiments of this utility model, please refer to Figure 1 The headlight body 1 has an air vent 2 at the top center, which provides a channel for the exhaust of hot air during the heat dissipation process, helps to maintain the normal air circulation in the heat dissipation system and ensures the heat dissipation effect.

[0025] The working principle of the heat dissipation structure for the reflector bowl of the vehicle lamp provided by this utility model is as follows: When the vehicle lamp is working, it emits light and generates heat. Since the lamp housing 11 is connected to the reflector bowl body 8 through the heat sink housing 5, the heat is first transferred to the heat sink housing 5 through thermal conduction. The heat sink housing 5 has a large heat dissipation surface area, which allows the heat to be better dissipated into the surrounding air. The first heat dissipation fan 9 and the second heat dissipation fan 10 in the middle above cooperate to form a vertically connected heat dissipation airflow channel. At this time, the fan 7 works to drive the airflow. The water-cooled cold air passes through the heat dissipation airflow channel, which accelerates the airflow speed on the surface of the heat sink housing 5, so that the heat on the heat sink housing 5 can be carried away more quickly. At the same time, the heat will be conducted to the water cooling device body 4. The coolant flows in the pipe, absorbs heat and rises in temperature, realizing heat exchange of the heat sink, thereby indirectly cooling the reflector bowl body 8 and achieving effective heat dissipation of the vehicle lamp reflector bowl.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
