Description

Technical Field

[0001] The present invention relates to the field of matrix headlights, and in particular to an ADB matrix headlight that is easy to install. Background Art

[0002] With the continuous advancement of automobile technology, the automotive lighting system has also evolved from halogen bulbs to xenon headlights and then to LED headlights. As an upgraded version of LED headlights, ADB matrix headlights integrate more advanced technology and smarter functions. The development of this technology not only improves the safety of night driving, but also improves the convenience and comfort of driving.

[0003] Currently, matrix headlights generally use a rear active air cooling system, which achieves heat exchange by driving airflow with a high-speed fan. However, due to the air flow and heat conduction efficiency in a confined space, such systems often face a bottleneck in heat dissipation performance, that is, long-term operation can easily lead to the risk of heat accumulation in LED modules or laser light sources, which in turn leads to life problems such as accelerated light decay and component aging.

After being cooled by the semiconductor refrigeration plate, these liquid waters are circulated in the liquid cooling system, effectively taking away the heat generated by the matrix lamp. In addition, the system ensures efficient heat dissipation under different conditions with the help of the flexible cooperation between the independent air-conditioning system and the passenger air-conditioning system.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0024] Among them, the drawings are only used for illustrative purposes and represent only schematic diagrams rather than actual pictures, and should not be understood as limitations on this patent; in order to better illustrate the embodiments of the present invention, some parts of the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product.

[0025] Existing matrix headlight cooling solutions, whether active air cooling or liquid cooling, have problems of low efficiency and frequent coolant replacement.

[0026] The present invention provides a technical solution, referring to Figure 1-Figure 3 , an ADB matrix headlight that is easy to install, comprising a shell 1, a lampshade 2 is arranged at the rear end of the shell 1, a mounting seat 15 is arranged at the bottom of the lampshade 2, a transmission cover 3 is arranged at the front end of the shell 1, an inner shell 4 adapted to the structure of the shell 1 is arranged in the shell 1, a cavity is arranged between the outer shell 1 and the inner shell 4, a plurality of partitions 7 are evenly arranged in the cavity, the outer shell 1 and the inner shell 4 are divided into a plurality of refrigeration chambers by the partitions 7, and the plurality of refrigeration chambers are interconnected; Specifically, refer to Figure 3 and Figure 7 The refrigeration chamber near the lampshade 2 is connected to an air intake pipe 6, which is connected to the air conditioning system in the vehicle. The refrigeration chamber away from the lampshade 2 is connected to an exhaust pipe 14, which is connected to the outside. The air intake pipe 6 is connected to a corner of the bottom of the refrigeration chamber. The partition 7 is located in a corner of the refrigeration chamber and is provided with an air hole 12. The air holes 12 of the two connected partitions 7 are arranged diagonally.

[0027] Further, see Figure 4-Figure 7 A first condensation plate 10 is fixedly provided on the inner wall of the top of the outer shell 1, and a second condensation plate 11 is fixedly provided on the outer wall of the bottom of the inner shell 4 above the inner wall of the bottom of the outer shell 1. The first condensation plate 10 and the second condensation plate 11 are provided with a plurality of condensation holes in a matrix; a first wedge plate 8 is fixedly provided on the top of the inner shell 4, and a second wedge plate 9 is fixedly provided on the inner wall of the bottom of the outer shell 1. A plurality of water flow holes 13 are provided at the connection between the partitions 7 and the tops of the first wedge plate 8 and the second wedge plate 9. The plurality of water flow holes 13 between two adjacent partitions 7 are arranged in a staggered manner, and the aperture size of the water flow hole 13 is smaller than the aperture size of the pore 12.

[0028] When the headlight is working, the air intake pipe 6 is connected to the air outlet end of the air-conditioning system in the car, and the air-conditioning system in the car is used to dissipate the heat of the headlight. It should be noted that the air intake pipe 6 is connected to the independent air-conditioning system in the car, and the air intake pipe 6 is also connected to the air-conditioning system for passengers in the car. When the air-conditioning system for passengers in the car is not turned on, the independent air-conditioning system is connected to the air intake pipe 6. When it is hot in summer, the air intake pipe 6 is connected to both the independent air-conditioning system and the passenger air-conditioning system to increase the cooling power.

[0029] Secondly, when the cold air of the air conditioner is blown into the refrigeration chamber through the air inlet pipe 6, Figure 3 As shown, since the air inlet pipe 6 is arranged at a bottom corner near the lampshade 2, and the air hole 12 of the partition 7 on the side of the refrigeration chamber away from the air inlet pipe 6 is opened at a diagonal position with respect to the air inlet pipe 6, the cold air can be circulated in the entire refrigeration chamber, and the residence time of the cold air is increased. Similarly, the air holes 12 on the partition 7 on the other side of another adjacent refrigeration chamber are arranged diagonally with the air holes 12 in the previous refrigeration chamber. In this way, the cold air is continuously circulated, so that the entire cold air is gradually dispersed to the periphery of the inner shell 4, that is, the cavity in the outer shell 1 and the inner shell 4, and the cavity of the outer shell 1 and the inner shell 4 is divided into a plurality of refrigeration chambers by the partition 7, so that the refrigeration, that is, the heat dissipation, can be made more uniform, and the cooling effect on the inner shell 4 is improved.

[0030] That is to say, when the cold air is injected into the bottom refrigeration chamber from the air inlet pipe 6, it flows step by step to the exhaust pipe 14 through the diagonal air holes 12, forming a "snake-shaped" circulation path. The layered chamber design prolongs the residence time of the cold air, improves the heat exchange efficiency on the surface of the inner shell 4, and finally realizes the synergistic effect of the multi-stage refrigeration chamber. The partition 7 is set between the outer shell 1 and the inner shell 4 to separate the refrigeration chamber into multi-stage interconnected refrigeration chambers. Combined with the diagonal layout of the air holes 12 structure, the air conditioning cold air circulates in the chamber along the "snake-shaped path"; the residence time of the cold air is prolonged, forming a cooling airflow field that evenly wraps the inner shell; At the same time, with the matrix condensation hole design of the first / second condensation plate, when the cold air contacts the condensation plate, a local low-temperature zone is formed at the edge of the condensation hole, which accelerates the condensation of water vapor and provides a stable water source for the liquid cooling system. It can also increase the heat exchange area between the cold air and the inner shell 4, realize the gradient conduction of heat, and improve the efficiency compared with traditional air cooling.

[0031] Further, refer to Figure 4 The bottom of the refrigeration chamber near the lampshade 2 is connected to a water storage tank 19 for collecting liquefied water in the refrigeration chamber. The ends of the first wedge plate 8 and the second wedge plate 9 away from the air inlet pipe 6 are higher than the ends near the air inlet pipe 6. A water collecting pipe 21 is provided at the bottom of the refrigeration chamber at the lower end of the second wedge plate 9. One end of the water collecting pipe 21 is connected to the refrigeration chamber, and the other end is connected to the top of the water storage tank 19. Specifically, refer to Figure 8-Figure 12 The portion of the lampshade 2 located inside the inner shell 4 is provided with a matrix lamp 5, and the matrix lamp 5 is provided with a heat conducting plate 16, and the heat conducting plate 16 is in a matrix structure adapted to the structure of the matrix lamp 5, and heat sinks 17 are symmetrically provided on both sides of the heat conducting plate 16, and the two heat sinks 17 are respectively provided with a first liquid cooling box 18 and a second liquid cooling box 27, and the outer periphery of the heat sink 17 is coated with liquid gold, and the heat sink 17 is fitted with the first liquid cooling box 18 and the second liquid cooling box 27 through the liquid gold.

[0032] Among them, a water pump 22 is arranged on the water storage tank 19, and the first liquid cooling tank 18 and the second liquid cooling tank 27 are connected through a connecting pipe 25 at one end away from the lampshade 2. A water inlet pipe 24 is arranged at one end of the first liquid cooling tank 18 near the lampshade 2, one end of the water inlet pipe 24 is connected to the first liquid cooling tank 18, and the other end is connected to the output end of the water pump 22. A water pumping pipe 23 is arranged at the suction end of the water pump 22, one end of the water pumping pipe 23 is connected to the suction end of the water pump 22, and the other end is connected to the bottom of the water storage tank 19, and a water outlet pipe 26 is arranged at one end of the second liquid cooling tank 27 near the lampshade 2, one end of the water outlet pipe 26 is connected to the second liquid cooling tank 27, and the other end is connected to the top of the water storage tank 19.

[0033] When the liquid cooling system is working, the liquid water flowing into the water storage tank 19 through the water collecting pipe 21 is continuously accumulated. When the depth detection device detects that the water in the water storage tank 19 can meet the needs of the first liquid cooling tank 18 and the second liquid cooling tank 27 to realize the liquid cooling cycle, the water pump 22 is triggered to start. During this period, the semiconductor refrigeration sheet 20 continuously cools the liquid water in the water storage tank 19. When the water pump 22 is started, the refrigeration power is increased. Then the water pump 22 extracts the cooled liquid water from the water storage tank 19 and enters the first liquid cooling tank 18 through the water inlet pipe 24. The first liquid cooling tank 18 is wrapped with the heat sink 17, and then the matrix lamp 5 is equipped with The heat generated by the matrix lamp 5 is conducted to the heat sink 17 through the heat conduction plate 16, and the heat of the heat sink 17 is taken away by the first liquid cooling box 18, and then enters the second liquid cooling box 27 through the connecting pipe 25, and the heat of the heat sink 17 on the other side of the heat conduction plate 16 is taken away by the second liquid cooling box 27, and finally flows back to the water storage tank 19 to form a cycle. During this period, liquid water will continue to increase in the refrigeration chamber, so the liquid water in the water storage tank 19 will continue to increase. As long as the vehicle is working, the headlights are working, and the air conditioning refrigeration system is working, liquid water will be continuously generated, thereby solving the problem of frequent replacement of coolant.

[0034] In other words, a dual-mode liquid cooling closed-loop system is realized through the three-stage heat transfer structure of heat conduction plate 16-liquid gold-liquid cooling box, and through the dual mechanism of air-conditioning cold air (primary cooling) + self-circulating condensed water (secondary cooling), the air-conditioning cold air takes priority to bear 60%-70% of the basic heat dissipation load, and when the temperature of the lamp group is high and the liquid water accumulates to a certain level, the liquid cooling mechanism is started. This synergistic mechanism stabilizes the operating temperature of the lamp group in the range of 45-55℃ (the traditional solution is 60-75℃), extending the service life by more than 3 times, and realizing "zero replenishment" maintenance of the coolant.

[0035] Further, see Figure 4 A semiconductor refrigeration plate 20 is provided at the bottom of the water tank 19 for cooling the liquid in the water tank 19. The first liquid cooling box 18 and the second liquid cooling box 27 realize liquefied water circulation with the water tank 19 through a water pump 22. The water tank 19 is connected to a drain pipe 28 for discharging excess liquefied water.

[0036] It is worth mentioning that a depth detection device is provided in the water storage tank 19. When the liquid water in the water storage tank 19 meets the amount of liquid water circulating in the first liquid cooling tank 18 and the second liquid cooling tank 27, the depth detection device starts the water pump 22.

[0037] In summary, through the triple innovation of spatial cascading air duct design, condensed water self-circulation mechanism, and intelligent temperature-controlled liquid cooling system, the difficulties of traditional heat dissipation solution efficiency and coolant replacement cost have been overcome, and while ensuring an operating temperature of ≤55°C, the cooling system can achieve "zero consumables" operation.

[0038] Working principle of the present invention: When the entire headlight is working, the entire headlight is installed in front of the vehicle through the mounting bracket 15, and then the air intake pipe 6 is connected to the air outlet end of the air conditioning system in the vehicle, and the air conditioning system in the vehicle is used to dissipate the heat of the headlight. It should be noted that the air intake pipe 6 is connected to the independent air conditioning system in the vehicle, and the air intake pipe 6 is also connected to the air conditioning system for passengers in the vehicle. When the air conditioning system for passengers in the vehicle is not turned on, the independent air conditioning system is connected to the air intake pipe 6. When it is hot in summer, the air intake pipe 6 is connected to both the independent air conditioning system and the passenger air conditioning system to increase the cooling power.

[0039] Specifically, when the cold air of the air conditioner is blown into the refrigeration chamber through the air inlet pipe 6, Figure 3As shown, since the air inlet pipe 6 is arranged at a bottom corner near the lampshade 2, and the air hole 12 of the partition 7 on the side of the refrigeration chamber away from the air inlet pipe 6 is opened at a diagonal position with respect to the air inlet pipe 6, the cold air can be circulated in the entire refrigeration chamber, and the residence time of the cold air is increased. Similarly, the air holes 12 on the partition 7 on the other side of another adjacent refrigeration chamber are arranged diagonally with the air holes 12 in the previous refrigeration chamber. In this way, the cold air is continuously circulated, so that the entire cold air is gradually dispersed to the periphery of the inner shell 4, that is, the cavity in the outer shell 1 and the inner shell 4, and the cavity of the outer shell 1 and the inner shell 4 is divided into several refrigeration chambers by the partition 7, so that the refrigeration, that is, the heat dissipation is more uniform, and the cooling effect on the inner shell 4 is improved, so as to achieve cooling and heat dissipation of the matrix lamp 5, and with the help of the refrigeration system of the air conditioner, the air blown out through the air inlet pipe 6 has a better cooling effect than the natural wind, and at the same time, relying on the air conditioning system in the car, the entire heat dissipation is more reasonable.

[0040] However, relying solely on cold air for cooling and heat dissipation may not be ideal, so liquid cooling is needed to cool the entire headlight. However, the background technology mentions that the use of liquid cooling requires the replacement of coolant during the maintenance stage, which invisibly increases the maintenance cost. However, combined with the above and common sense, it can be seen that when the cold air blown out by the air conditioner encounters a heat flow, it will condense the moisture in the air to form liquid water. Therefore, the present invention also makes full use of this to collect liquid water, and then cool the liquid water to achieve circulating cooling. The condensed liquid water in the cavity of the outer shell 1 and the inner shell 4 may not be very stable. Therefore, the first condensation plate 10 and the second condensation plate 11 are used to accelerate the formation of liquid water, because a number of condensation holes are opened thereon. The specific principle is common sense and will not be elaborated on here. In this way, when the cold air circulates through a number of refrigeration chambers, it will gradually A large amount of liquid water condenses in the chamber and on the first condensation plate 10 and the second condensation plate 11, and then falls on the first wedge plate 8 and the second wedge plate 9 respectively. The first wedge plate 8 and the second wedge plate 9 are wedge-shaped structures. Therefore, relying on gravity, the liquid water will flow to a lower place, and then gradually converge into the refrigeration chamber closest to the lampshade 2 through the water flow hole 13, and flow into the water storage tank 19 through the water collecting pipe 21 for storage. It should be noted that the aperture of the water flow hole 13 is smaller than the air hole 12, so the cold air is mainly transmitted and circulated through the air hole 12. At the same time, the water flow holes 13 are staggered, which is more conducive to the cold air staying in the corresponding refrigeration chamber and preventing the cold air from circulating through the water flow holes 13. Combined with the continuous circulation of liquid water through the water flow holes 13, the water flow holes 13 are mainly used to circulate liquid water, but a small amount of cold air convection is inevitable.

[0041] Then, the liquid water that flows into the water storage tank 19 through the water collecting pipe 21 continues to gather. When the depth detection device detects that the water in the water storage tank 19 can meet the needs of the first liquid cooling tank 18 and the second liquid cooling tank 27 to realize liquid cooling circulation, the water pump 22 is triggered to start. During this period, the semiconductor refrigeration plate 20 continuously cools the liquid water in the water storage tank 19. When the water pump 22 is started, the refrigeration power will be increased. Then the water pump 22 draws the cooled liquid water from the water storage tank 19 and enters the first liquid cooling tank 18 through the water inlet pipe 24. The first liquid cooling tank 18 wraps the heat sink 17, and then the matrix lamp 5 is equipped with a heat conducting plate 16. The heat emitted by the matrix lamp 5 is conducted to the heat sink 17 through the heat conducting plate 16, and the heat sink is transferred to the heat sink 17 through the first liquid cooling tank 18. 17 is taken away, and then enters the second liquid cooling box 27 through the connecting pipe 25, and the heat of the heat sink 17 on the other side of the heat conducting plate 16 is taken away by the second liquid cooling box 27, and finally flows back to the water storage tank 19 to form a cycle. During this period, liquid water will be continuously added in the refrigeration chamber, so the liquid water in the water storage tank 19 will continue to increase. As long as the vehicle is working, the headlights are working, and the air conditioning refrigeration system is working, liquid water will be continuously generated, solving the problem of frequent replacement of coolant. At the same time, the continuous liquid water will eventually exceed the volume of the water storage tank 19, and the excess liquid water will flow to the outside through the drain pipe 28; in this way, the cold air circulation cooling is combined with the liquid water generated by itself for liquid cooling and heat dissipation, thereby improving the overall cooling effect of the headlight.

[0042] To summarize, in the air cooling stage: the cold air from the air conditioner passes through the air intake pipe 6 → the refrigeration chamber (partition 7 / air hole 12) → the condensation plate cools the lamp group and produces condensed water → the exhaust gas is discharged from the exhaust pipe 14; in the water cooling stage: the condensed water passes through the wedge plate → the water flow hole 13 → the water collecting pipe 21 → the water storage tank 19 → the water pump 22 → the liquid cooling box circulates and dissipates heat → the reflux water tank completes the closed loop; thereby effectively solving the cooling solution for the matrix headlights, whether it is active air cooling or liquid cooling, there are problems of low efficiency and frequent replacement of coolant.
