Description

Technical Field

[0001] This utility model relates to the technical field of water-cooled radiators for automotive lights, and in particular to a water-cooled radiator for a front combination lamp. Background Technology

[0002] In automotive lighting systems, the front combination lamp is a key component for ensuring driving safety. Its performance stability and heat dissipation are closely related. With the continuous upgrading of automotive lighting technology, LED light sources are widely used in front combination lamps due to their advantages such as low energy consumption, long lifespan, and high brightness. However, high-power LEDs generate a lot of heat when working. If the heat cannot be dissipated in time, it will cause the lamp beads to overheat, which will not only reduce the lighting brightness and shorten the lifespan, but may also cause problems such as light source color decay and circuit failure, seriously affecting driving safety.

[0003] Front combination lights typically rely on natural air cooling or simple heat sinks for heat dissipation. However, due to the limited internal space and complex structure of these lights, their heat dissipation efficiency is low, making it difficult to meet the heat dissipation requirements of high-power LEDs. This problem is particularly pronounced in high-temperature environments or during long-distance driving. As consumers demand higher brightness and stability from automotive lighting, and with the development of intelligent and electric vehicles, front combination lights are integrating more and more functions, further increasing heat generation. Traditional heat dissipation methods are no longer adequate. Therefore, existing water-cooled radiators are prone to poor heat dissipation when the lamp body space is narrow, the LED power is high, and the internal heat dissipation space is insufficient. This can lead to lamp body deformation, melting of plastic parts, and LED light attenuation, thereby reducing the effectiveness of the equipment. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a front combination lamp water-cooled heat sink, which aims to improve the existing lamp water-cooled heat sinks in the prior art. When the lamp body space is relatively narrow, the LED lamp power is large, and the internal heat dissipation space is insufficient, the heat dissipation is prone to poor, resulting in lamp body deformation, plastic parts melting and LED light attenuation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a front combination lamp water-cooled radiator, including a lamp housing, with flexible hoses connected to the top left and right sides of the lamp housing, a radiator shell fixedly connected to the top of the flexible hoses, a radiator base provided on the inner bottom of the radiator shell, a lens PCBA provided on the top of the radiator base, a lens bracket provided on the top of the lens PCBA, a lens fixedly connected to the top of the lens bracket, a screw threadedly connected to the bottom of the radiator base, a second water connector provided on the inner top of the flexible hose, a cooling water pipe provided on the outer wall of the second water connector, and inlet and outlet ports provided on the outside of the cooling water pipe.

[0006] Metal retaining rings are provided at both the upper and lower ends of the outer wall of the hose.

[0007] A condenser is provided at the top center of the lens PCBA.

[0008] The bottom of the lamp housing is connected to a water pipe connector.

[0009] The outer wall of the water connector is connected to a sealing plug.

[0010] A sealing gasket is provided at the bottom center of the lens PCBA.

[0011] This utility model has the following beneficial effects: In this invention, the ventilation radiator assembly uses a sealing gasket and a water pipe connector to ensure the sealing performance of the radiator assembly. This, combined with a hose, metal retaining ring, and sealing plug, ensures that the water pipe sealing is not affected when the lens module moves. Furthermore, the radiator shell and cooling water pipe form a circuit with the car radiator, ensuring continuous heat dissipation of the radiator assembly. This improves heat dissipation efficiency, reduces high-temperature deformation of plastic parts, and avoids the risk of light decay of LED lights due to high-temperature operation. Therefore, it avoids the situation of lamp deformation caused by high temperature. At the same time, it occupies little space, has high heat dissipation efficiency, and can solve the problem of low heat dissipation efficiency of conventional radiators, meeting the needs of daily use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see the appendix Figure 1 - Appendix Figure 3 An embodiment of this utility model is provided: a front combination lamp water-cooled radiator, including a lamp housing 1, with flexible hoses 2 connected to the top left and right sides of the lamp housing 1, a radiator shell 3 fixedly connected to the top of the flexible hoses 2, a radiator base 4 provided at the bottom inner side of the radiator shell 3, a lens PCBA 5 provided at the top of the radiator base 4, a lens bracket 6 provided at the top of the lens PCBA 5, a lens 7 fixedly connected to the top of the lens bracket 6, a screw 8 threadedly connected to the bottom of the radiator base 4, a water connector 2 14 provided at the top inner side of the flexible hose 2, a cooling water pipe 15 provided on the outer wall of the water connector 2 14, and an inlet and outlet 16 opened on the outside of the cooling water pipe 15. Specifically, the radiator base 4 uses a material with high thermal conductivity to quickly conduct heat generated inside the headlight, ensuring stable operation of the headlight. A lens bracket 6 is further installed on the top of the lens PCBA5. The lens bracket 6 not only provides stable support for the lens 7 but also adjusts its position and angle, ensuring precise projection of the light emitted by the headlight according to design requirements, improving lighting effect and signal clarity. The lens 7 is fixedly connected to the top of the lens bracket 6, effectively focusing and scattering light. The bottom of the radiator base 4 is fixed with screws 8 using a threaded connection. The water connector 14 is for headlight water cooling, allowing for precise connection to external water cooling equipment to achieve coolant circulation.

[0016] Please see the appendix Figure 1 - Appendix Figure 3 A condenser 12 is provided at the top center of the lens PCBA5, a water connector 11 is connected to the bottom of the lamp housing 1, metal retaining rings 9 are provided at the upper and lower ends of the outer wall of the hose 2, a sealing plug 10 is connected to the outer wall of the water connector 11, and a sealing gasket 13 is provided at the bottom center of the lens PCBA5. Specifically, the lamp housing 1 serves as the outer protective structure of the vehicle lamp, and the water connector 11 is the water cooling interface of the vehicle lamp, which can be connected to the external water cooling pipeline. The metal retaining ring 9 can effectively prevent the hose 2 from loosening. In order to prevent water leakage during the connection process, a sealing plug 10 is connected to the outer wall of the water connector 11. The sealing plug 10 is usually made of rubber and can fit tightly in the sealing barrier at the connection between the water connector 11 and the external pipeline.

[0017] Working principle: The ventilation radiator assembly uses sealing gasket 13 and water pipe connector 14 to ensure the sealing performance of the radiator assembly. This, combined with hose 2, metal retaining ring 9, and sealing plug 10, ensures that the movement of lens module 7 does not affect the water pipe sealing. Furthermore, the radiator housing 3 and cooling water pipe 15 form a circuit with the car radiator, ensuring continuous heat dissipation of the radiator assembly. This improves heat dissipation efficiency, reduces high-temperature deformation of plastic parts, avoids the risk of light decay of LED lights at high temperatures, reduces space requirements, and saves a lot of space by changing the heat dissipation method of the headlight radiator. It also improves heat dissipation efficiency, reduces the aging speed of LED lights, and avoids the deformation of lamps due to high temperatures. At the same time, it occupies little space, has high heat dissipation efficiency, and solves the problems of low heat dissipation efficiency and large space occupation of conventional radiators, meeting daily use needs.
