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 scope of 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.

[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 scope of 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, including a vehicle light 100 and a heat dissipation component 200. The heat dissipation component 200 includes a fan 210, and the heat dissipation component 200 is disposed below the fan 210. The vehicle light 100 includes a groove and a lamp plate structure. The lamp plate structure is disposed in the groove, and the heat dissipation component 200 is attached to the surface of the lamp plate structure. Part of the structure of the heat dissipation component 200 is exposed outside the groove, and the heat dissipation air duct located in the middle of the heat dissipation component 200 covers the lamp beads on the lamp plate structure.

[0034] It should be noted that when the temperature control system of this application is working, the lamp panel structure of the vehicle lamp 100 is installed in its own recess, and the heat dissipation component 200 is attached to the surface of the lamp panel structure, so that the heat generated by the lamp panel structure during operation can be directly transferred to the heat dissipation component 200. In this application, the light-emitting part of the lamp bead is the part of the vehicle lamp 100 that generates the most heat. The heat dissipation duct located in the middle of the heat dissipation component 200 covers the lamp bead on the lamp panel structure, which can specifically dissipate the heat generated by the lamp bead. The fan 210 is located above the heat dissipation component 200. After the fan 210 is started, it can accelerate the airflow around the heat dissipation component 200 and push the heat in the heat dissipation duct to be quickly discharged. In this application, the vehicle lamp 100 should also be provided with an outer shell (not shown in the attached figure). The edge of the outer shell will be provided with multiple ventilation holes. The fan 210 drives the part of the heat dissipation component 200 structure exposed outside the recess to exchange heat with the outside air, thereby realizing the temperature control of the lamp panel structure and the lamp bead.

[0035] Furthermore, the close fit between the lamp panel structure of the headlight 100 and the heat dissipation component 200 shortens the heat transfer path, allowing the heat generated by the lamp panel structure to be quickly transferred to the heat dissipation component 200, reducing heat accumulation. The heat dissipation component 200 is positioned within a recess, enabling better compatibility with headlight assemblies of different vehicle models.

[0036] According to one embodiment of this application, the heat dissipation component 200 includes a base 230, the surface of which is provided with a plurality of through holes, and bolts for connecting to the lamp panel structure are provided in the through holes.

[0037] It should be noted that after the bolts pass through the through holes and connect to the lamp panel structure, the lamp panel structure can be firmly fixed to the surface of the base 230, so that the lamp panel structure and the base 230 form a tight fit. The heat generated by the lamp panel structure during operation will be directly transferred to the base 230 through the contact surface. The base 230 is connected to the lamp panel structure through the bolts in the through holes, which can improve the stability of the connection between the lamp panel structure and the heat dissipation component 200, prevent the lamp panel structure from loosening due to bumps during vehicle operation, and prevent the heat transfer path from being interrupted, thus affecting the heat dissipation effect.

[0038] According to one embodiment of this application, the heat dissipation assembly 200 further includes a cooling chip 240. A square groove is provided on the base 230, and the cooling chip 240 is disposed in the square groove. A circuit board is provided on one side of the cooling chip 240, and part of the cooling chip 240 is disposed on the upper surface of the circuit board to press the circuit board.

[0039] It should be noted that the cooling element 240 of the heat dissipation assembly 200 is positioned and installed via a square slot on the base 230, ensuring that the cooling element 240 will not shift after installation. A circuit board is located on one side of the cooling element 240, and part of the cooling element 240's structure adheres to and presses against the circuit board, ensuring a secure fit between the cooling element 240 and the circuit board and guaranteeing a smooth electrical connection between them. When the cooling element 240 is operating, it can quickly absorb heat transferred from the base 230 and conduct the heat out and dissipate it to the surrounding heat dissipation structure.

[0040] The square slot on the base 230 positions the cooling chip 240, ensuring its stable installation on the heat dissipation assembly 200 without increasing its overall size, thus better compressing the space required by the heat dissipation assembly 200. The cooling chip 240's structure is partially positioned on the upper surface of the circuit board and presses against it, enhancing the stability of the connection between the cooling chip 240 and the circuit board. This prevents the connection from loosening due to bumps during vehicle operation, ensuring stable power supply and reliable operation of the cooling chip 240.

[0041] 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.

[0042] It should be noted that the bottom of the fins 250 of the heat dissipation assembly 200 is in close contact with one side of the cooling plate 240, allowing the heat absorbed by the cooling plate 240 to be quickly transferred to the fins 250 during operation. The fins 250 are positioned on one side of the fan 210, and their airflow direction is consistent with that of the fan 210. When the fan 210 starts and accelerates airflow, it simultaneously drives the air around the fins 250 to circulate rapidly, allowing the heat absorbed by the fins 250 to be quickly carried away and dissipated to the outside. The fins 250, through their structure, increase the heat dissipation area, and in conjunction with the airflow from the fan 210, further assist the heat dissipation assembly 200 in dissipating the heat generated by the lamp panel structure of the headlight 100.

[0043] Furthermore, the bottom of the fins 250 is positioned close to the cooling plate 240, shortening the heat transfer path and reducing heat loss during the heat transfer process. This allows the heat absorbed by the cooling plate 240 to be quickly transferred to the fins 250 for dissipation, effectively improving the heat dissipation efficiency of the cooling plate 240. Since the fins 250 themselves have a large heat dissipation area, they can further expand the overall heat dissipation range of the heat dissipation assembly 200. Combined with the blowing action of the fan 210, and with both having the same airflow direction, the airflow can effectively assist the heat dissipation of the fins 250, accelerating the heat dissipation speed. The fins 250 are positioned on one side of the fan 210, eliminating the need to increase the overall volume of the heat dissipation assembly 200. This allows for better adaptation to the recessed structure of the headlight 100 and the automotive headlight assembly, without affecting overall installation compatibility.

[0044] According to one embodiment of this application, the fin 250 has a clamping base protruding towards the cooling plate 240. A housing 260 surrounds the outer side of the fin 250, and a plurality of holes are symmetrically opened on the periphery of the housing 260. The axial direction of the holes is correspondingly spaced from the fin 250.

[0045] 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.

[0046] It should be noted that the clamping base of the fin 250 protrudes towards the cooling plate 240. After installation, the clamping base can tightly abut against the cooling plate 240, further reinforcing the fit between the fin 250 and the cooling plate 240 and ensuring smooth heat transfer between them. The housing 260 surrounds the outside of the fin 250, protecting it from damage by external impacts. Multiple holes symmetrically opened on the periphery of the housing 260, with their axial directions corresponding to the spacing of the fin 250, guide air to flow along the spacing direction of the fin 250. Four symmetrical connecting rods on the surface of the housing 260 away from the fins 250 are used to mount and fix the fan 210, ensuring that the fan 210 is stable after installation. The ventilation hole in the middle of the housing 260 is on the same axis as the rotating shaft of the fan 210. After the fan 210 is started, the airflow can be blown to the fins 250 through the ventilation hole. In conjunction with the airflow guided by the hole, the airflow on the surface of the fins 250 is accelerated, which promotes the rapid dissipation of the heat absorbed by the fins 250, thereby assisting the heat dissipation component 200 in achieving efficient temperature control.

[0047] According to one embodiment of this application, the pressing base of the fin 250 protrudes towards and abuts against the cooling plate 240, which enhances the tightness of the fit between the fin 250 and the cooling plate 240, reduces the gap between them, reduces heat loss during heat transfer, and allows the heat transferred by the cooling plate 240 to be conducted to the fin 250 more efficiently. The housing 260 surrounds the fin 250, and the symmetrically opened holes on its periphery correspond to the spacing and orientation of the fin 250, which optimizes the airflow path, allowing air to pass through the fin spacing more fully and improving the heat dissipation efficiency of the fin 250. Four symmetrically arranged connecting rods can securely mount the fan 210, preventing the fan 210 from shaking or shifting during vehicle operation.

[0048] According to one embodiment of this application, the bottom of the housing 260 is fitted to one side of the base 230. A first housing sleeve 261 is provided on one side of the housing 260. The first housing sleeve 261 extends along the length direction of the housing 260. A first base 231 is provided on one side of the circuit board corresponding to the first housing sleeve 261. The first housing sleeve 261 and the first base 231 are fitted together to fix the circuit board.

[0049] It should be noted that the bottom of the housing 260 is fitted to one side of the base 230, allowing some of the heat transferred from the base 230 to be conducted to the housing 260, thus assisting the base 230 in heat dissipation. A first housing sleeve 261 is provided on one side of the housing 260, extending along the length of the housing 260. A first base 231 is provided on one side of the circuit board corresponding to the first housing sleeve 261. During installation, the first housing sleeve 261 and the first base 231 are aligned and fitted together to achieve relative fixation of the circuit board with the housing 260 and the base 230.

[0050] According to one embodiment of this application, the cold end of the cooling chip 240 is disposed near the groove, and the hot end of the cooling chip 240 is disposed in conjunction with the pressing base of the fin 250.

[0051] When the lamp board temperature is set to ≥70℃, the temperature signal can be transmitted through the NTC temperature sensor. After the circuit board receives the signal command, it sends a start signal for the cooling chip 240, and the fan 210 runs at full speed. It is worth noting that the heat dissipation component 200 works by starting the fan 210 first, and then starting the cooling chip 240.

[0052] After continuous cooling, when the temperature is ≤65℃, the NTC temperature sensor transmits the temperature signal. After receiving the signal command, the circuit board sends a stop signal to the cooling chip 240, and the cooling chip 240 stops working. The fan 210 stops running after a delay of 30 seconds.

[0053] When the temperature inside the lamp is below 10℃, the NTC temperature sensor transmits a temperature signal. After the circuit board receives the signal command, it switches the current direction and sends a signal to start the cooling of the cold end of the cooling chip 240, which conducts heat to the inside of the headlight 100 to achieve the defrosting and defogging function.

[0054] According to one embodiment of this application, the housing 260 is provided with arc-shaped grooves 262 on both sides in the same direction. The arc-shaped grooves 262 are located below the fan 210, and the orientation of the arc-shaped grooves 262 is consistent with the orientation of the fins 250.

[0055] It should be noted that the housing 260 has arc-shaped grooves 262 on both sides in the same direction. The arc-shaped grooves 262 are installed below the fan 210, and their orientation is consistent with the orientation of the fins 250. After the fan 210 is started, the airflow generated blows downwards, and the arc-shaped grooves 262 can guide the airflow. Because the arc-shaped grooves 262 are oriented in the same direction as the fins 250, they can guide the airflow between the gaps of the fins 250. At the same time, the arc-shaped structure of the arc-shaped grooves 262 can reduce the resistance during airflow, allowing the airflow to pass through the fins 250 more smoothly.

[0056] Furthermore, the arc-shaped grooves 262 are arranged on both sides of the housing 260 in the same direction and located below the fan 210. The orientation of the arc-shaped grooves 262 is consistent with the orientation of the fins 250. This can guide the airflow generated by the fan 210 to act on the fins 250, avoid the airflow dispersion which would lead to a decrease in heat dissipation, and allow the airflow to contact the fins 250 more fully, effectively improving the heat dissipation efficiency of the fins 250.

[0057] According to one embodiment of this application, the groove extends from one end of the headlight 100 to the middle, the width of the groove gradually decreases along the extension direction of the groove body, and one end of the groove is fitted to the end face of the base 230.

[0058] It should be noted that the groove on the headlight 100 extends from one end to the middle, with the width of the groove gradually decreasing along its extension direction. This gradually decreasing width structure can adapt to the installation dimensions of the base 230, facilitating precise alignment between the base 230 and the groove. The groove's one end is fitted against the end face of the base 230, enabling proper positioning of the base 230 and the headlight 100. This ensures that the heat dissipation component 200 is stably installed within the groove of the headlight 100 via the base 230. Simultaneously, the fitted design shortens the heat transfer path between the base 230 and the headlight 100, allowing heat generated by the headlight 100's lamp plate structure to be transferred not only to the base 230 but also, with the aid of the fitting surface, to the headlight 100's housing for dissipation. The gradually decreasing width of the groove fully utilizes the internal space of the headlight 100, preventing the groove from occupying too much internal space and affecting the installation of other components. Together with the base 230, it ensures a stable connection between the heat dissipation component 200 and the headlight 100.
