Description
Technical Field
[0001] This application relates to the field of automotive lighting heat dissipation technology, specifically to a temperature control system and an automotive lighting system. Background Technology
[0002] In modern automotive lighting systems, the heat dissipation performance of automotive lamps plays a crucial role in their lifespan and lighting effect. With the development of automotive lighting technology, the research and optimization of automotive lamp cooling methods have become an important aspect of ensuring safe driving and improving user experience.
[0003] Currently, automotive headlights primarily use passive cooling. One type is natural heat dissipation, which achieves passive heat dissipation by increasing the heat dissipation area of the heat sink fins; the other is forced cooling, which achieves heat dissipation by adding a cooling fan.
[0004] However, both of these passive cooling methods have certain drawbacks. Natural heat dissipation results in a large heat dissipation structure, making it difficult to integrate with the headlight assemblies of many vehicle models in practical applications, thus limiting its use. While forced cooling introduces a cooling fan, the actual heat dissipation effect is not ideal because the cooling fan itself operates in a high-temperature environment, failing to fully meet the high-efficiency heat dissipation requirements of automotive lights.

[0007] According to one embodiment of this application, the heat dissipation assembly further includes a base and a cooling plate. A portion of a heat-conducting pipe is embedded between the base and the cooling plate. The base is located on the outer side of the headlight panel, and the bent portion of the heat-conducting pipe abuts against the edge of the base.
[0008] According to one embodiment of this application, the heat dissipation assembly further includes fins, the bottom of which is in close contact with one side of the cooling plate, the air outlet direction of the fins is consistent with the air outlet direction of the fan, and the fins are disposed on one side of the fan.
[0009] According to one embodiment of this application, a shell surrounds the fins and cooling plates, and multiple holes are formed on the periphery of the shell, with corresponding arrangements between the holes and the fins.
[0010] The shell has four symmetrically arranged connecting rods on the side surface away from the fins. A fan is fitted on the connecting rods. A ventilation hole is opened in the middle of the shell, and the ventilation hole and the fan's rotating shaft are on the same axis.

[0028] In modern automotive lighting systems, the heat dissipation performance of automotive lamps plays a crucial role in their lifespan and lighting effect. With the development of automotive lighting technology, the research and optimization of automotive lamp cooling methods have become an important aspect of ensuring safe driving and improving user experience.
[0029] Currently, automotive headlights primarily use passive cooling. One type is natural heat dissipation, which achieves passive heat dissipation by increasing the heat dissipation area of the heat sink fins; the other is forced cooling, which achieves heat dissipation by adding a cooling fan.
[0030] However, both of these passive cooling methods have certain drawbacks. Natural heat dissipation results in a large heat dissipation structure, making it difficult to integrate with the headlight assemblies of many vehicle models in practical applications, thus limiting its use. While forced cooling introduces a cooling fan, the actual heat dissipation effect is not ideal because the cooling fan itself operates in a high-temperature environment, failing to fully meet the high-efficiency heat dissipation requirements of automotive lights.
[0031] Figure 1 This is an exploded view of the fan assembly provided in an embodiment of this application;
[0032] Figure 2 This is a cross-sectional structural diagram showing the connection between the fan assembly and the headlight panel provided in an embodiment of this application.
[0033] Reference Figure 1 and Figure 2As shown, this application provides a temperature control system, which includes a headlight panel 100 and a heat dissipation assembly 200. The heat dissipation assembly 200 includes a fan 210 and a heat pipe 220. The heat pipe 220 is disposed below the fan 210. The headlight panel 100 includes at least two panels. A groove is formed in the middle of one side of the two panels. The two panels are joined together. A portion of the heat pipe 220 is disposed in the space formed by the groove. The heat pipe 220 exposed outside the groove is bent, and the bent portion is connected to the fan 210.
[0034] It should be noted that the heat pipe 220 penetrates the groove of the headlight panel 100, enabling it to quickly absorb the heat generated by the headlight panel 100 and transfer it to the area where it connects to the fan 210 at the bend. When the fan 210 operates, it accelerates airflow, carrying away the heat from the heat pipe 220. Compared to traditional forced cooling that relies solely on a fan for heat dissipation, this method improves heat dissipation efficiency and effectively avoids problems such as light decay and shortened lifespan caused by overheating of the automotive headlights. Secondly, embedding the heat pipe 220 into the groove formed by the assembly of the headlight panel 100 avoids the increased volume problem caused by adding structure as with natural heat dissipation, allowing the heat dissipation component 200 to better adapt to the headlight assemblies of different models and optimizing the internal space layout of the automotive headlights. In addition, the close cooperation between the heat pipe 220, the headlight panel 100, and the fan 210 reduces the impact of loose components or misalignment on the heat dissipation effect, ensuring stable heat dissipation of the automotive headlights under various operating conditions and providing reliable protection for the safety of automotive lighting.
[0035] According to one embodiment provided in this application, the curvature of the bent portion of the heat pipe 220 should be less than or equal to 90°, or the curvature of the bent portion of the heat pipe 220 should be greater than or equal to 90°.
[0036] It should be noted that when the bend in the heat pipe 220 has an arc of less than or equal to 90°, the heat conduction resistance at the bend is effectively reduced. A smaller bend arc allows for a smoother heat transfer path within the heat pipe 220, enabling rapid heat transfer from the headlight panel 100 to the area connected to the fan 210, further improving heat dissipation efficiency. Simultaneously, the smaller bend arc design helps optimize the spatial layout of the heat dissipation component 200, making the entire temperature control system structure more compact and facilitating installation and adaptation in headlight assemblies of different vehicle models, reducing installation difficulties caused by space constraints.
[0037] When the bend in the heat pipe 220 has an arc greater than or equal to 90°, the contact area between the heat pipe and the air can be increased to a certain extent. A larger bend arc allows the heat pipe to form a more three-dimensional heat dissipation structure near the fan 210, enabling the airflow generated by the fan 210 to make more thorough contact with the surface of the heat pipe 220, thereby enhancing the convective heat dissipation effect. Furthermore, the larger bend arc also strengthens the connection between the heat pipe 220 and the headlight panel 100 and the fan 210. During vehicle operation, even when subjected to bumps and vibrations, it effectively reduces the decrease in heat conduction efficiency caused by component movement, further ensuring the stability and reliability of the automotive headlight temperature control system.
[0038] According to one embodiment of this application, the heat dissipation assembly 200 further includes a base 230 and a cooling chip 240. A portion of a heat-conducting pipe 220 is embedded between the base 230 and the cooling chip 240. The base 230 is located on the outer side of the headlight panel 100, and the bent portion of the heat-conducting pipe 220 abuts against the edge of the base 230.
[0039] It should be noted that the base 230 is located on the outside of the headlight panel 100, providing stable support for the entire heat dissipation assembly 200, making the heat conduction path between the cooling chip 240, the heat pipe 220, and the headlight panel 100 more stable and reliable. The addition of the cooling chip 240 can actively cool the heat transferred by the heat pipe 220, improving heat dissipation efficiency, quickly reducing the temperature of the headlight panel 100, and effectively extending the service life of the automotive headlight.
[0040] Furthermore, the cold end of the TEC cooling chip used in this application is attached to the heat pipe 220 and is tightly attached to the heat pipe 220 by thermal grease to ensure that the cooling energy is evenly transferred to the heat pipe 220. The hot end of the TEC cooling chip is arranged adjacent to the fins 250, and the fan 210 rotates to dissipate the heat from the hot end of the TEC cooling chip.
[0041] In the temperature control system of this application, the cooling element 240 is typically made of semiconductor material. Based on the Peltier effect, the function of its hot and cold ends can be switched by changing the direction of the current flowing through the cooling element.
[0042] When heat dissipation is required for the headlight panel 100, the current flows through the cooling chip 240 in a specific direction, making the side that contacts the heat pipe 220 the cold end, absorbing the heat transferred by the heat pipe 220, and the other side the hot end, dissipating the heat through the base 230 and the fan 210.
[0043] When the ambient temperature is too low and the temperature of the headlight panel 100 needs to be increased (such as to prevent frost from affecting the lighting), the current direction is switched, and the side of the cooling chip 240 that is in contact with the heat pipe 220 becomes the hot end, releasing heat to the heat pipe 220, thereby heating the headlight panel 100.
[0044] Furthermore, the heat pipe 220 can rapidly transfer the heat generated by the headlight panel 100 to the cooling element 240 for cooling, preventing heat accumulation on the headlight panel 100. On the other hand, the bent portion of the heat pipe 220 abuts against the edge of the base 230, further enhancing the effectiveness of heat transfer. This allows heat to be conducted more smoothly from the headlight panel 100 to the base 230, and then, with the help of the airflow from the fan 210, the heat is quickly dissipated into the external environment. This improves overall heat dissipation performance and enables precise control of the automotive headlight temperature, ensuring stable operation under various conditions and providing safer and more reliable lighting for nighttime driving. Without increasing the overall size, the heat dissipation function has been upgraded, improving the applicability and versatility of the temperature control system.
[0045] According to one embodiment of this application, the heat dissipation assembly 200 further includes fins 250. The bottom of the fins 250 is closely attached to one side of the cooling plate 240. The air outlet direction of the fins 250 is consistent with the air outlet direction of the fan 210, and the fins 250 are disposed on one side of the fan 210.
[0046] It should be noted that in this application, fins 250 are added to the heat dissipation assembly 200, and the bottom of the fins 250 is in close contact with the cooling plate 240, with the air outlet direction consistent with the fan 210 and located on the same side as the fan 210. This improves the heat dissipation performance of the temperature control system. The close contact between the bottom of the fins 250 and the cooling plate 240 enhances the heat conduction efficiency of the hot end of the cooling plate 240. The heat generated by the cooling plate 240 during operation can be quickly transferred to the fins 250. Utilizing the larger surface area of the fins 250, the heat is dispersed. Compared with heat dissipation by a single cooling plate, this increases the contact area with the air and enhances the heat exchange effect.
[0047] Furthermore, the airflow direction of fin 250 is consistent with that of fan 210, creating a synergistic heat dissipation effect. The airflow generated by fan 210 flows smoothly through the gaps in fin 250, carrying away heat from the surface of fin 250, making the heat dissipation process more efficient. This avoids the problem of reduced heat dissipation efficiency caused by turbulent airflow, ensuring that heat can be quickly and orderly dissipated into the external environment, further improving the overall heat dissipation performance of the temperature control system.
[0048] Furthermore, the fins 250 are positioned on one side of the fan 210, optimizing the spatial layout of the heat dissipation assembly 200. Without significantly increasing the size of the heat dissipation assembly, the space around the fan is fully utilized, achieving an upgrade in heat dissipation function. Simultaneously, the stable structural design enhances the vibration resistance of the heat dissipation assembly; even when the vehicle is driving under complex road conditions, the close cooperation between the fins 250, the cooling plate 240, and the fan 210 ensures stable heat transfer.
[0049] According to one embodiment of this application, a housing 260 surrounds the outer sides of the fins 250 and the cooling plate 240. Multiple holes are formed on the periphery of the housing 260, and these holes correspond to the fins 250.
[0050] The housing 260 has four symmetrically arranged connecting rods on the side surface away from the fins 250. A fan 210 is sleeved on the connecting rods. A ventilation hole is opened in the middle of the housing 260, and the ventilation hole and the rotating shaft of the fan 210 are on the same axis.
[0051] It should be noted that the outer casing 260 surrounds the fins 250 and the cooling element 240, and, in conjunction with the design of the perforations, connecting rods, and ventilation holes, further optimizes the performance of the temperature control system. The casing 260 provides physical protection for the fins 250 and the cooling element 240, effectively preventing external dust, moisture, and mechanical damage from affecting the core heat dissipation components and extending the service life of the heat dissipation assembly 200. The multiple perforations on its periphery, corresponding to the fins 250, can precisely guide airflow, allowing outside air to flow more smoothly over the surface of the fins 250, enhancing the convective heat dissipation effect and increasing the heat dissipation rate.
[0052] The symmetrical connecting rods on the side of the housing 260 away from the fins 250, which are sleeved with the fan 210, not only simplify the assembly process of the heat dissipation assembly 200, but also ensure that the relative positions of the fan 210, fins 250, and cooling fins 240 are fixed, preventing component displacement due to vehicle vibration and affecting heat dissipation efficiency. Simultaneously, the coaxial design of the ventilation holes in the middle of the housing 260 with the fan 210's rotating shaft reduces airflow resistance during fan operation, allowing the airflow generated by the fan 210 to pass through the housing more efficiently, working in conjunction with the fins 250 to form a continuous heat dissipation airflow channel, further improving overall heat dissipation performance. Furthermore, this structure optimizes the space utilization of the heat dissipation assembly 200, integrating various components through the housing. While ensuring heat dissipation functionality, it makes the entire system structure more compact and orderly, facilitating adaptation to the installation requirements of automotive lights in different vehicle models.
[0053] According to one embodiment of this application, the bottom of the housing 260 is fitted to one side of the base 230. A first sleeve 261 is provided on the side of the housing 260 away from the bent portion of the heat pipe 220. The first sleeve 261 extends along the length of the housing 260. A first base 231 is provided on one side of the base 230 corresponding to the first sleeve 261. The first sleeve 261 and the first base 231 are fitted together to fix the housing 260.
[0054] It should be noted that the bottom of the housing 260 fits snugly against the base 230, and the sleeve design of the first housing 261 and the first base 231 further enhances the overall performance of the temperature control system. The snug fit between the bottom of the housing 260 and the base 230 increases the contact area between the two, making the center of gravity distribution of the heat dissipation component 200 more reasonable and effectively resisting the bumps and vibrations during vehicle operation. The sleeve structure of the first housing 261 and the first base 231 firmly fixes the housing 260 to the base 230, preventing the components from loosening due to vibration, ensuring the relative position stability of core components such as the cooling chip 240, fins 250, and heat pipe 220, and maintaining an efficient heat conduction path.
[0055] Furthermore, the way the first housing 261 and the first base 231 are connected is similar to a "plug and play" modular design. Installers can quickly assemble the housing 260 and the base 230 without complicated tools or cumbersome operations, which greatly improves production efficiency. At the same time, when a component fails, the housing 260 and the base 230 can be easily separated for targeted repair or replacement.
[0056] The housing 260 and the base 230 fit tightly together, providing a more efficient path for heat transfer. After receiving heat from the heat pipe 220, the base 230 can quickly conduct the heat to the housing 260 through the contact surface. With the help of the peripheral holes and fins 250 of the housing, heat dissipation is accelerated. The stable connection between the first housing 261 and the first base 231 ensures the continuity of the entire heat dissipation channel, avoids heat dissipation dead zones caused by component displacement, and further improves the heat dissipation stability and reliability of the temperature control system under different operating conditions.
[0057] According to one embodiment of this application, a through hole is provided in the middle of the first substrate 231, and a power supply pipe is provided at the through hole.
[0058] According to one embodiment of this application, a PCB board 270 is provided on the side of the cooling chip 240 away from the bent portion of the heat pipe 220. The PCB board 270 is disposed inside the base 230 and does not contact the heat pipe 220.
[0059] It should be noted that the through-hole in the center of the first substrate 231 and the placement of power conduits, along with the layout of the PCB board 270 within the base 230, further enhance the functionality and reliability of the temperature control system. The power conduits, through the through-hole in the first substrate 231, provide stable power to components such as the cooling chip 240 and the fan 210. The concealed conduits optimize the internal wiring layout of the heat dissipation assembly 200, avoiding wear and short-circuit risks caused by exposed wiring. Furthermore, the structural protection of the first substrate 231 improves the stability of power transmission, ensuring a continuous and stable power supply to all electrical components even under the complex vibrations of a vehicle.
[0060] Integrating the PCB board 270 into the base 230 allows for precise control over the Peltier effect current direction switching of the cooling chip 240 and the speed adjustment of the fan 210, enhancing the intelligence of the temperature control system. Furthermore, avoiding contact with the heat pipe 220 prevents the high temperature transferred by the heat pipe from affecting the electronic components on the PCB board 270, ensuring the stability and lifespan of the circuit system. This layout also facilitates subsequent circuit upgrades or troubleshooting, allowing maintenance personnel to quickly locate the PCB board 270 for inspection and maintenance without requiring extensive disassembly of the entire heat dissipation structure.
[0061] Furthermore, the power supply piping and PCB board 270 are arranged in coordination with other components of the heat dissipation assembly 200. The reasonable layout of the power supply piping does not interfere with the airflow path for heat dissipation, and the installation of the PCB board 270 within the base 230 does not affect the heat transfer efficiency between the base and the housing 260 and the heat pipes 220.
[0062] Additionally, it should be noted that this application uses an NTC temperature sensor. The intelligent temperature control logic constructed using the NTC temperature sensor and PCB board 270 enables the temperature control system to possess precise temperature sensing and adaptive adjustment capabilities. In high-temperature scenarios, when the lamp board temperature is ≥70℃, the system responds in the order of "fan starts first, then TEC chip starts." This timing control avoids the efficiency reduction problem caused by the TEC chip starting when heat dissipation is insufficient. By pre-establishing an airflow channel through the fan, the heat generated by the TEC chip can be quickly removed. When the temperature is ≤65℃, the TEC chip stops working first, and the fan runs for a 30-second delay, continuously removing residual heat from the system to prevent temperature rebound and ensure that the lamp board temperature remains stable within a safe range.
[0063] In low-temperature environments (temperature <10℃), the system achieves heating by switching the current direction of the TEC chip, and conducts heat to the inside of the headlight through the heat spreader. This design breaks through the limitation of traditional car lights that rely solely on natural heating for defrosting.
[0064] According to one embodiment of this application, the groove extends from the end face of the headlight panel 100 to the middle, the width of the groove gradually decreases along the extension direction of the groove, and one end of the groove is fitted to the end face of the heat pipe 220.
[0065] It should be noted that the design of the groove extending from the end face of the headlight panel 100 to the middle with a gradual change in width, and fitting snugly against the end face of the heat pipe 220, brings multi-dimensional performance improvements to the temperature control system. In terms of heat conduction, this gradually decreasing width structure of the groove creates a "heat flow convergence" effect, allowing the heat generated by the headlight panel 100 to be transferred to the heat pipe 220 more efficiently along the groove. The heat conduction gradient created by the change in groove width prevents heat from accumulating during conduction.
[0066] In terms of structural stability, the design of the groove extending from the end face to the middle increases the contact area between the headlight panel 100 and the heat pipe 220, and the groove fits snugly against the end face of the heat pipe 220, making the connection between the two more tight and stable. This tightly fitted structure can effectively resist vibration and bumps during vehicle operation, prevent the problem of reduced heat conduction efficiency due to component loosening, and ensure that heat can still be stably and efficiently transferred from the headlight panel to the heat pipe under complex working conditions, maintaining the stable operation of the temperature control system.
[0067] According to one embodiment provided in this application, this application also provides a vehicle light that includes a temperature control system described in the above solution.
