Description

Technical Field

[0001] This invention relates to the field of LED vehicle light heat dissipation technology, specifically to an integrated high-power LED vehicle light heat dissipation component. Background Technology

[0002] LED automotive lights refer to automotive lights that use LEDs (light-emitting diodes) as the light source. LED automotive lights generate a lot of heat when they are working. The integrated high-power LED automotive light heat dissipation component is an integrated thermal management component that integrates the LED heat source substrate, thermal conduction transition structure, heat dissipation fins, optional heat pipes / automotive-grade fans, and sealed positioning interfaces into a whole module. It is specifically used for high-power LED headlights in automobiles to achieve rapid heat dissipation from the LED chip and temperature control protection.

[0003] When LED headlights are working, heat is first absorbed by copper plates and copper pipes and conducted to the heat sink fins. Then, the axial fan quickly dissipates the heat from the heat sink fins to the external environment. However, when the fan is running, the airflow generated carries heat out and also flows towards the LED headlights. Some of the hot airflow may flow to the LED headlights, which may cause the temperature of the surrounding casing to be too high, affecting the heat exchange of the LED headlights and causing the temperature at the LED headlights to be too high, resulting in a decrease in the luminous efficiency of the LED headlights. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an integrated high-power LED automotive light heat dissipation component, including a protective shell, heat dissipation fins fixedly connected to the bottom of the protective shell, a fan compartment fixedly connected to the outer wall of the heat dissipation fins, and a cooling fan fixedly connected to the inner wall of the fan compartment, and further including:

[0005] The lighting mechanism is installed on the front and back of the protective housing, and includes several arc-shaped guide blocks fixedly connected to the front and back of the protective housing;

[0006] A flow guiding mechanism is installed on the inner wall of the arc-shaped flow guiding block. The flow guiding mechanism includes an arc-shaped flow guiding groove formed on the inner wall of the arc-shaped flow guiding block.

[0007] A gathering mechanism is installed on the outer wall of the protective housing, and the gathering mechanism includes a partition ring disposed on the outer wall of the protective housing;

[0008] The system includes six arc-shaped guide blocks, three arc-shaped guide blocks on the front and three on the back of the protective shell, and six arc-shaped guide slots. When the vehicle needs lighting, the power to the lighting mechanism is turned on to generate a light source for illumination. During the lighting process, the cooling fan is activated to continuously dissipate heat and cool the lighting mechanism.

[0009] Preferably, the lighting mechanism further includes:

[0010] A connecting component is installed on the inner wall of the protective housing;

[0011] The heat dissipation component is installed on the inner wall of the connecting component.

[0012] Preferably, the flow guiding mechanism further includes:

[0013] The flow diversion component is installed on the inner wall of the arc-shaped flow guide block;

[0014] The flow divider assembly is installed on the inner wall of the arc-shaped flow guide block.

[0015] Preferably, the aggregation mechanism also includes:

[0016] The air distribution assembly is installed on the inner wall of the fan compartment.

[0017] Preferably, the connecting assembly includes a copper substrate fixedly connected to the inner wall of the protective housing, a connecting chuck fixedly connected to the outer wall of the protective housing, and the outer wall of the connecting chuck fixedly connected to the inner wall of the partition ring.

[0018] Preferably, the heat dissipation component includes LED beads fixedly connected to the inner wall of the copper substrate, and a plurality of heat dissipation copper pipes fixedly connected to the inner wall of the protective shell, with the outer walls of the plurality of heat dissipation copper pipes fixedly connected to the inner wall of the copper substrate.

[0019] There are two heat dissipation copper pipes. When the vehicle needs lighting while driving, the power is turned on and the copper substrate is energized, which enables the LED beads to produce light source for illumination. When the LED beads are energized, a large amount of heat is generated and conducted into the copper substrate. The heat is then conducted through the copper substrate to the heat dissipation copper pipe. The heat dissipation copper pipe uses the vapor-liquid phase change of its internal working fluid to achieve heat conduction, quickly transferring the heat from the LED beads to the heat dissipation fins. The heat dissipation fins then absorb the heat, and the temperature of the heat dissipation fins continues to rise.

[0020] When the power is turned on, the cooling fan will start running and generate airflow. The airflow will pass through the heat sink fins and exchange heat with the surface of the heat sink fins. The heat exchanged airflow will diffuse towards the LED beads.

[0021] Preferably, the flow guiding component includes a connecting pipe that runs through the bottom of the arc-shaped flow guide block, and the outer walls of several connecting pipes are all connected through the inner wall of the fan compartment.

[0022] The bottom openings of several connecting pipes all face the top of the cooling fan, and the inner walls of several arc-shaped guide channels are all fixedly connected with flow dividers.

[0023] There are six connecting pipes and six flow dividers. When the cooling fan is running, some of the airflow generated will first enter the connecting pipes and flow into the arc-shaped flow guide channel. The airflow entering the arc-shaped flow guide channel will come into contact with the flow dividers.

[0024] Preferably, the diversion component includes an arc-shaped flow guide groove 2 formed on the inner wall of the arc-shaped flow guide block, and the inner wall of the protective shell is provided with a plurality of flow grooves;

[0025] Among them, there are six arc-shaped guide channels and six flow channels. Part of the airflow in the arc-shaped guide channel is diverted by the diverter plate, and part of the airflow in the arc-shaped guide channel flows into the arc-shaped guide channel. The airflow in the arc-shaped guide channel eventually flows into the flow channel, directly guiding the airflow to dissipate heat to the internal area of ​​the protective shell around the LED beads.

[0026] When the airflow flows in the flow channel, it can fully contact and exchange heat with the inner wall of the protective shell. The airflow flowing through the arc-shaped guide channel will contact the outer wall of the protective shell and exchange heat with it. At the same time, the protective shell dissipates heat both inside and outside, which can effectively reduce the temperature inside the protective shell around the LED beads. This effectively prevents the LED beads from becoming too hot due to local high temperature of the protective shell, which would cause a decrease in the luminous efficiency of the LED beads, thus ensuring the lighting performance and stability of the LED beads.

[0027] Preferably, the air distribution assembly includes an air-gathering ring fixedly connected to the inner wall of the fan compartment, and the top of each of the air-gathering rings is provided with a number of air distribution grooves.

[0028] The airflow generated by the cooling fan passes through the connecting pipe and is guided by the bottom conical surface of the air-gathering ring, flowing into the air-gathering ring. The gathered airflow is then sprayed upwards again through multiple air-distribution slots, which redistribute the airflow so that it flows evenly into the heat dissipation fins, allowing for sufficient heat exchange. This effectively prevents the airflow generated by the cooling fan from entering the connecting pipe and weakening the airflow in the corresponding area of ​​the heat dissipation fins, thus ensuring a stable heat exchange effect.

[0029] After passing through the heat exchange fins, the airflow comes into contact with the partition ring. The partition ring blocks the hot airflow, causing it to deviate from the area of ​​the arc-shaped guide block. This makes it difficult for the hot airflow to come into contact with the arc-shaped guide block, effectively preventing the surface temperature of the arc-shaped guide block from rising due to prolonged exposure to hot airflow. The low-temperature airflow flowing inside the arc-shaped guide block is reheated by the wall surface, thus ensuring that the airflow dissipating heat from the protective shell has a low temperature and maintaining a stable heat dissipation effect.

[0030] The present invention has the following beneficial effects:

[0031] (1) In this invention, when the LED lamp bead is powered on for lighting, a large amount of heat is generated and conducted into the copper substrate. The heat is transferred to the heat sink fins through the connecting components. The temperature of the heat sink fins will continue to rise. When the cooling fan is started, airflow will first enter the connecting pipe. The airflow is guided by the flow guiding components and the flow diversion components. At the same time, the heat sink is simultaneously cooled inside and outside the protective shell. This can effectively reduce the temperature inside the protective shell around the LED lamp bead and effectively prevent the LED lamp bead from being too hot due to the local temperature of the protective shell. This will prevent the LED lamp bead from being too hot and thus reduce the luminous efficiency of the LED lamp bead, thereby ensuring the lighting performance and stability of the LED lamp bead.

[0032] (2) In this invention, the airflow generated by the operation of the cooling fan is guided by the bottom conical surface of the air-gathering ring after passing through the connecting pipe, and then flows into the air-gathering ring. The collected airflow will be sprayed upward again through multiple air-distribution grooves. The multiple air-distribution grooves will redistribute the airflow, so that the airflow flows evenly into the heat dissipation fins, and fully exchange heat with the heat dissipation fins. This effectively prevents the airflow generated by the cooling fan from entering the connecting pipe during operation, which would weaken the airflow in the corresponding area of ​​the heat dissipation fins, thereby ensuring a stable heat exchange effect.

[0033] (3) In this invention, the airflow after heat exchange through the heat dissipation fins will come into contact with the partition ring. The partition ring blocks the hot airflow, causing the hot airflow to deviate from the area of ​​the arc-shaped guide block, making it difficult for the hot airflow to come into contact with the arc-shaped guide block. This effectively prevents the hot airflow from scouring the arc-shaped guide block for a long time, which would cause its surface temperature to rise. The low-temperature airflow flowing inside the arc-shaped guide block is heated a second time by the wall surface, thereby ensuring that the airflow dissipating heat from the protective shell has a low temperature and maintaining a stable heat dissipation effect.

[0034] (4) In this invention, after the airflow flowing in the middle flow channel exchanges heat with the protective shell, the airflow temperature will rise. Subsequently, the airflow will come into contact with the LED beads, so that the airflow in contact with the LED beads has a higher initial temperature. This effectively prevents the low-temperature airflow used for heat dissipation of the protective shell from directly contacting the LED beads, which would cause the LED beads to drop too much in temperature and create a large temperature difference between them and the copper substrate. This prevents long-term hot and cold cycles from causing fatigue of the LED beads' solder joints and thermal stress cracking. Attached Figure Description

When in use, when the car needs lighting, the power of the lighting mechanism 1 is turned on to generate a light source for lighting. During the lighting operation, the cooling fan 16 is started to continuously dissipate heat and cool down the lighting mechanism 1.

[0059] Aggregation mechanism 3 also includes:

[0060] Air distribution assembly 31 is installed on the inner wall of fan compartment 15.

[0061] The connecting component 11 includes a copper substrate 111 fixedly connected to the inner wall of the protective housing 13, and a connecting chuck 112 fixedly connected to the outer wall of the protective housing 13. The outer wall of the connecting chuck 112 is fixedly connected to the inner wall of the partition ring 301.

[0062] The heat dissipation assembly 12 includes LED beads 121 fixedly connected to the inner wall of the copper substrate 111, and a plurality of heat dissipation copper pipes 122 fixedly connected to the inner wall of the protective shell 13. The outer walls of the plurality of heat dissipation copper pipes 122 are all fixedly connected to the inner wall of the copper substrate 111.

[0063] Two heat dissipation copper pipes 122 are provided. When the vehicle needs lighting while driving, the power is turned on and the copper substrate 111 is energized, causing the LED beads 121 to generate light source for illumination. When the LED beads 121 are energized, a large amount of heat is generated and conducted into the copper substrate 111. The heat is then conducted again through the copper substrate 111 to the heat dissipation copper pipes 122. The heat dissipation copper pipes 122 use the vapor-liquid phase change of the working fluid inside to achieve heat conduction, quickly transferring the heat from the LED beads 121 to the heat dissipation fins 14. The heat dissipation fins 14 then absorb the heat, and the temperature of the heat dissipation fins 14 continues to rise.

[0064] When the power is turned on, the cooling fan 16 will start running and generate airflow. The airflow will pass through the heat sink fins 14 and exchange heat with the surface of the heat sink fins 14. The heat exchanged airflow will diffuse towards the LED beads 121.

[0065] The flow guiding component 21 includes a connecting pipe 211 that runs through the bottom of the arc-shaped flow guiding block 101, and the outer walls of several connecting pipes 211 are all connected through the inner wall of the fan compartment 15.

[0066] The bottom openings of several connecting pipes 211 all face the top of the cooling fan 16, and the inner walls of several arc-shaped guide grooves 201 are all fixedly connected with flow dividers 212.

[0067] There are six connecting pipes 211 and six flow dividers 212. When the cooling fan 16 is running, some of the airflow generated will first enter the connecting pipes 211 and flow into the arc-shaped flow guide groove 201 through the connecting pipes 211. The airflow entering the arc-shaped flow guide groove 201 will come into contact with the flow dividers 212.

[0068] The diversion component 22 includes an arc-shaped guide groove 221 formed on the inner wall of the arc-shaped guide block 101, and a plurality of flow grooves 222 formed on the inner wall of the protective shell 13.

[0069] Among them, six arc-shaped guide channels 221 are provided, and six flow channels 222 are provided. Part of the airflow in the arc-shaped guide channel 201 will be diverted by the diverter plate 212, and part of the airflow in the arc-shaped guide channel 201 will flow into the arc-shaped guide channel 221. The airflow in the arc-shaped guide channel 201 will eventually flow into the flow channel 222, directly guiding the airflow to dissipate heat from the internal area of ​​the protective shell 13 around the LED bead 121.

[0070] When the airflow flows in the flow channel 222, it can fully contact and exchange heat with the inner wall of the protective shell 13. The airflow flowing through the arc-shaped guide channel 221 will contact the outer wall of the protective shell 13 and exchange heat with it. At the same time, the protective shell 13 can dissipate heat both inside and outside, which can effectively reduce the temperature inside the protective shell 13 around the LED bead 121. This effectively prevents the LED bead from becoming too hot due to the local temperature of the protective shell 13, which would cause the LED bead to become too hot and reduce the luminous efficiency of the LED bead. This ensures the lighting performance and stability of the LED bead.

[0071] The air distribution assembly 31 includes an air gathering ring 311 fixedly connected to the inner wall of the fan compartment 15, and a number of air distribution grooves 312 are opened on the top of the several air gathering rings 311.

[0072] The airflow generated by the cooling fan 16 passes through the connecting pipe 211 and is guided by the bottom conical surface of the air-gathering ring 311, flowing into the air-gathering ring 311. The gathered airflow is then sprayed upward through multiple air-distribution grooves 312, which redistribute the airflow so that it flows evenly into the heat dissipation fins 14, allowing for sufficient heat exchange. This effectively prevents the airflow generated by the cooling fan 16 from entering the connecting pipe 211 and weakening the airflow in the corresponding area of ​​the heat dissipation fins 14, thus ensuring a stable heat exchange effect.

[0073] After heat exchange through the heat dissipation fins 14, the airflow will come into contact with the partition ring 301. The partition ring 301 blocks the hot airflow, causing it to deviate from the area of ​​the arc-shaped guide block 101. This makes it difficult for the hot airflow to come into contact with the arc-shaped guide block 101, effectively preventing the surface temperature of the arc-shaped guide block 101 from rising due to prolonged exposure to hot airflow. The low-temperature airflow flowing inside the arc-shaped guide block 101 is reheated by the wall surface, thereby ensuring that the airflow dissipating heat from the protective shell 13 has a low temperature and maintaining a stable heat dissipation effect.

[0074] The number of the above structures is not limited. Those skilled in the art can freely set them according to actual needs, as long as the above structures are installed at the connection positions of the corresponding structures.

[0075] A specific application of this embodiment is as follows: When using this invention, the device is installed inside the headlight cover of a car. When the car needs lighting while driving, the copper substrate 111 is energized by turning on the power, causing the LED beads 121 to generate a light source for illumination. When the LED beads 121 are energized, a large amount of heat is generated and conducted into the copper substrate 111. The heat is then conducted again through the copper substrate 111 to the heat dissipation copper pipe 122. The heat dissipation copper pipe 122 uses the vapor-liquid phase change of its internal working fluid to achieve heat conduction, quickly transferring the heat from the LED beads 121 to the heat dissipation fins 14. The heat dissipation fins 14 then absorb the heat, and the temperature of the heat dissipation fins 14 continues to rise.

[0076] When the power is turned on, the cooling fan 16 will start running and generate airflow. The airflow will pass through the heat sink fins 14 and exchange heat with the surface of the heat sink fins 14. The heat exchanged airflow will diffuse towards the LED beads 121.

[0077] When the cooling fan 16 is running, some of the airflow generated will first enter the connecting pipe 211 and flow into the arc-shaped guide channel 201. The airflow entering the arc-shaped guide channel 201 will come into contact with the diverter plate 212 and be diverted again by the diverter plate 212. Some of the airflow in the arc-shaped guide channel 201 will flow into the arc-shaped guide channel 221. The airflow in the arc-shaped guide channel 201 will eventually flow into the flow channel 222, directly guiding the airflow to dissipate heat from the internal area of ​​the protective shell 13 around the LED bead 121.

[0078] When the airflow flows in the flow channel 222, it can fully contact the inner wall of the protective shell 13 and exchange heat. The airflow flowing through the arc-shaped guide channel 221 will contact the outer wall of the protective shell 13 and exchange heat with the outer wall of the protective shell 13. At the same time, the protective shell 13 can dissipate heat both inside and outside, which can effectively reduce the temperature inside the protective shell 13 around the LED bead 121. This effectively prevents the LED bead from being too hot due to the local temperature of the protective shell 13, which would cause the LED bead to be too hot and reduce the luminous efficiency of the LED bead. This ensures the lighting performance and stability of the LED bead.

[0079] After the airflow generated by the cooling fan 16 passes through the connecting pipe 211, it is guided by the bottom conical surface of the air-gathering ring 311 and flows into the air-gathering ring 311. The gathered airflow will then be ejected upward through multiple air-distribution grooves 312. The multiple air-distribution grooves 312 will redistribute the airflow, so that the airflow flows evenly into the heat dissipation fins 14, and fully exchange heat with the heat dissipation fins 14. This effectively prevents the airflow generated by the cooling fan 16 from entering the connecting pipe 211 during operation, which would weaken the airflow in the corresponding area of ​​the heat dissipation fins 14, thus ensuring a stable heat exchange effect.

[0080] After heat exchange through the heat dissipation fins 14, the airflow will come into contact with the partition ring 301. The partition ring 301 blocks the hot airflow, causing the hot airflow to deviate from the area of ​​the arc-shaped guide block 101, making it difficult for the hot airflow to come into contact with the arc-shaped guide block 101. This effectively prevents the surface temperature of the arc-shaped guide block 101 from rising due to prolonged hot airflow scouring. The low-temperature airflow flowing inside the arc-shaped guide block 101 is reheated by the wall surface, thereby ensuring that the airflow dissipating heat from the protective shell 13 has a low temperature and maintains a stable heat dissipation effect.

[0081] The airflow flowing within the intermediate flow channel 222 exchanges heat with the protective housing 13, causing the airflow temperature to rise. Subsequently, the airflow comes into contact with the LED beads 121, such as... Figure 7 As shown, the airflow that comes into contact with the LED bead 121 has a high initial temperature, which effectively prevents the low-temperature airflow used for heat dissipation of the protective housing 13 from directly contacting the LED bead 121, which would cause the temperature of the LED bead 121 to drop too much, resulting in a large temperature difference between it and the copper substrate 111. This prevents long-term hot and cold cycles from causing fatigue of the solder joints and thermal stress cracking of the LED bead 121.
