Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat dissipation device technology, and in particular to a light source module with uniform heat dissipation. Background Technology
[0002] A gap between the radiator and the fan allows airflow to escape through the side gap, resulting in significant airflow loss, low utilization, and reduced cooling efficiency. When the gap between the fan and the radiator is large, the airflow distribution becomes uneven, leading to insufficient cooling in some areas. This uneven airflow distribution not only reduces cooling efficiency but may also cause uneven temperature distribution inside the equipment, affecting its stability and reliability, and potentially impacting its lifespan over time. Utility Model Content
[0003] The main purpose of this invention is to propose a light source module with uniform heat dissipation, which aims to solve the problem of insufficient heat dissipation and low heat dissipation efficiency caused by excessive gap between the heat sink and the fan in the prior art.
[0004] To achieve the above objectives, this utility model proposes a light source module with uniform heat dissipation, comprising: a lamp body, a heat dissipation pipe, an air guide shell, and a first heat sink. A first heat source and a second heat source are provided on the left and right sides of the lamp body. The heat dissipation pipe includes a first section and a second section. The air guide shell includes an air duct, an air inlet, a first air outlet, and a second air outlet. The air duct has a recessed internal structure. The first air outlet is located on the left side of the air duct, the second air outlet is located on the right side of the air duct, and the air inlet is located in the middle of the air duct. The first section of the heat dissipation pipe is attached to the first heat source, and the first heat sink is attached to the second heat source. The air guide shell is fastened to the lamp body such that the first air outlet covers the first section of the heat dissipation pipe, the second air outlet covers the first heat sink, and the second section of the heat dissipation pipe is located inside the air duct.
[0005] The design of the air guide shell ensures that the airflow can accurately cover the heat pipes and heat sinks, avoiding heat dissipation dead zones and thus improving heat dissipation efficiency. Using a heat pipe radiator can efficiently conduct heat, and then the airflow can further remove the heat, forming an efficient heat dissipation path.
[0006] Preferably, a heat transfer base is attached to the first heat source, and one section of the heat dissipation pipe is inserted into the heat transfer base.
[0007] The heat transfer base can further absorb heat from the primary heat source, allowing heat to be transferred more smoothly to the heat dissipation pipe.
[0008] Preferably, a second heat sink is attached to the heat transfer base, and the first air outlet cover is on the second heat sink.
[0009] The second heat sink is attached to the heat transfer base so that some of the heat absorbed by the heat pipe is transferred to the second heat sink and carried away by the airflow, thereby improving the heat dissipation efficiency.
[0010] Preferably, the distance l0 between the first air outlet wall and the second heat sink is ≤2mm, and the distance l1 between the second air outlet wall and the first heat sink is ≤2mm.
[0011] The distance between the air outlet wall and the heat sink is ≤2mm, which reduces air leakage when the air outlet blows towards the heat sink for heat dissipation, thereby improving the utilization rate of wind energy.
[0012] Preferably, a third heat sink is inserted into the second section of the heat sink pipe.
[0013] The third heat sink can improve the heat dissipation efficiency of the second section of the heat pipe.
[0014] Preferably, the interior of the air duct faces the lamp body, the air inlet faces the lower side of the lamp body, the two sections of the heat dissipation pipe are located between the air inlet and the lamp body, and the space between the two sections of the heat dissipation pipe and the lamp body forms a third air outlet and a fourth air outlet. The third air outlet and the fourth air outlet are located on the front and rear sides of the lamp body, respectively. The air entering from the air inlet can be blown out from the first air outlet, the second air outlet, the third air outlet, and the fourth air outlet, respectively.
[0015] Multiple air outlets allow for even heat dissipation, preventing localized overheating and ensuring rapid heat removal. This reduces airflow short-circuiting or eddies, improves heat dissipation efficiency, and decreases the number of fans required, thus lowering operating costs.
[0016] Preferably, the vertical distance l2 between the third air outlet and the fourth air outlet is 6-10 mm.
[0017] The vertical distance l2 between the third and fourth air outlets is set to 6-10mm, which allows for a suitable airflow and improves the uniform heat dissipation effect of the air guide shell.
[0018] Preferably, a sealing ring is provided between the first heat source and the heat transfer seat.
[0019] The sealing ring can prevent dust and water damage and protect the lamp body.
[0020] Preferably, the air inlet is located on the left side of the air guide shell.
[0021] Placing the air inlet close to the primary heat source can increase the airflow directed towards the heat source, thereby improving heat dissipation efficiency.
[0022] Beneficial effects: This utility model utilizes heat dissipation pipes and fins to absorb and dissipate heat from the heat source, and in conjunction with the air guide shell, it achieves a uniform heat dissipation effect for heat sources with different heat levels; the position of the air guide shell and the setting of the air outlet enhance the heat dissipation effect, avoid airflow eddies or short-circuiting, and prevent heat accumulation; the air guide shell of this utility model can use a single fan to achieve efficient heat dissipation, reducing the cost of use.

[0039] like Figures 1 to 10As shown, a light source module with uniform heat dissipation includes a lamp body 1, a heat dissipation pipe 2, an air guide shell 3, and a first heat sink 4. A first heat source 11 and a second heat source 12 are provided on the left and right sides of the lamp body 1. The heat dissipation pipe 2 includes a heat dissipation pipe section 21 and a heat dissipation pipe section 22. The air guide shell 3 includes an air duct 31, an air inlet 32, a first air outlet 33, and a second air outlet 34. The air duct 31 has a groove structure inside. The first air outlet 33 is located on the left side of the air duct 31, the second air outlet 34 is located on the right side of the air duct 31, and the air inlet 32 is located in the middle of the air duct 31. The heat dissipation pipe section 21 is attached to the first heat source 11, and the first heat sink 4 is attached to the second heat source 12. The air guide shell 3 is fastened to the lamp body 1, so that the first air outlet 33 covers the heat dissipation pipe section 21, the second air outlet 34 covers the first heat sink 4, and the heat dissipation pipe section 22 is located inside the air duct 31.
[0040] The design of the air guide shell 3 ensures that the airflow can accurately cover the heat pipe 2 and the heat sink, avoiding heat dissipation dead zones, thereby improving heat dissipation efficiency. The heat sink can efficiently conduct heat using the heat pipe 2, and then the airflow can further remove the heat, forming an efficient heat dissipation path.
[0041] The air guide shell 3 has a saddle-shaped structure, with an inner groove forming an air duct 31. The air duct 31 is an open structure with walls on three sides and no wall on one side. The opening of the air guide shell 3 faces upward. An air inlet 32 is opened on the bottom wall of the air duct 31, and the first air outlet 33 and the second air outlet 34 on the left and right sides are set upward. The heat dissipation pipe 2 is set in an L-shape. The vertical part on the left is the first heat dissipation pipe section 21, and the horizontal part on the right is the second heat dissipation pipe section 22. Multiple heat dissipation pipes 2 are set as a group. The heat dissipation fin is a ceramic heat dissipation fin. One side of the heat dissipation fin is a planar rectangular heat-conducting substrate, which is used to contact the heat source to absorb the heat from the heat source. The other side is a heat dissipation fin for heat dissipation. The heat from the first heat source 11 on the left side of the lamp body 1 is greater than the heat from the second heat source 12. Therefore, the heat dissipation pipe section 21 attached to the first heat source 11 can absorb the heat from the lamp body 1 more efficiently. The air guide shell 3 is attached to the lower side of the lamp body 1. The first air outlet 33 of the air guide shell 3 covers the first section 21 of the heat dissipation pipe. The heat absorbed by the first section 21 of the heat dissipation pipe will be dispersed to the second section 22 of the heat dissipation pipe to accelerate heat dissipation and prevent heat accumulation. The first heat sink 4 is attached to the second heat source 12 for heat dissipation. The second air outlet 34 of the air guide shell 3 covers the second heat sink 6. When the fan blows air into the air inlet 32 for heat dissipation, part of the air that has absorbed the heat from the heat dissipation pipe 2 is blown out from the first air outlet 33. The heat absorbed by the first section 21 of the heat dissipation pipe is conducted to the second section 22 of the heat dissipation pipe to quickly dissipate the heat, so that the heat is evenly diffused before heat dissipation. The other part of the air passes through the heat dissipation fins of the first heat sink 4 and carries away the heat from the second heat source 12, thus achieving the purpose of heat dissipation for the lamp body 1.
[0042] like Figure 2As shown, in some specific embodiments, a heat transfer base 5 is attached to the first heat source 11, and a section 21 of the heat dissipation pipe is inserted into the heat transfer base 5.
[0043] The heat transfer base 5 can further absorb the heat from the first heat source 11, so that the heat can be transferred to the heat dissipation pipe 2 more smoothly.
[0044] Since the heat dissipation pipe 2 is a tubular structure, its contact area with the heat source is small, resulting in low heat absorption efficiency. Therefore, a heat transfer seat 5 is set on the first heat source 11 to absorb the heat from the first heat source 11. The heat transfer seat 5 has multiple channels for inserting the heat dissipation pipe 2. When the heat transfer seat 5 is attached to the first heat source 11, it can transfer heat to the heat dissipation pipe 2 for heat dissipation, thereby increasing the rate of heat absorption from the first heat source 11.
[0045] In some specific embodiments, a second heat sink 6 is attached to the heat transfer base 5, and a first air outlet 33 covers the second heat sink 6.
[0046] The second heat sink 6 is attached to the heat transfer base 5 so that part of the heat absorbed by the heat pipe 2 is transferred to the second heat sink 6 and carried away by the airflow, thereby improving the heat dissipation efficiency.
[0047] The heat pipe 2 has a strong thermal conductivity and can quickly absorb heat. The second heat sink 6 can further absorb the heat from the heat pipe and transfer the heat to the second heat sink 6. The first air outlet 33 covers the second heat sink 6 to ensure that the airflow can evenly cover the heat sink. The heat is then effectively carried out by the airflow through the fins on the second heat sink 6.
[0048] In some specific embodiments, the distance l0 between the wall of the first air outlet 33 and the second heat sink 6 is ≤2mm, and the distance l1 between the wall of the second air outlet 34 and the first heat sink 4 is ≤2mm.
[0049] The distance between the air outlet wall and the heat sink is ≤2mm, which reduces air leakage when the air outlet blows towards the heat sink for heat dissipation, thereby improving the utilization rate of wind energy.
[0050] like Figure 8-9 As shown, in Figure 8 In region A, the distances between the left and rear walls of the first air outlet 33 and the second heat sink are both l0. The distance between the front wall and the second heat sink is also equal to l0, ensuring that the air blown from the first air outlet 33 to the second heat sink 6 does not easily leak out, reducing wind energy waste and improving wind energy utilization. Preferably, the distance l1 between the wall of the second air outlet 34 and the first heat sink 4 is l0. Since both have the same covering structure, the diagram and the label of l1 are omitted.
[0051] Furthermore, the second heat sink 2 is fixed to the heat transfer base 5, the first heat sink 4 is fixed to the second heat source 12, and the third heat sink 7 is fixed to the second section 22 of the heat sink by brazing, which can reduce contact thermal resistance and increase heat transfer effect.
[0052] Furthermore, applying silicone grease to the heat transfer base 5 can effectively reduce the thermal resistance between the heat transfer base 5 and the heat dissipation component, allowing heat to be transferred more smoothly.
[0053] In some specific embodiments, a third heat sink 7 is inserted into the second section 22 of the heat pipe.
[0054] The third heat sink 7 can improve the heat dissipation efficiency of the second section 22 of the heat pipe.
[0055] The third heat sink 7 is composed of heat dissipation fins. The third heat sink 7 is inserted on the second section 22 of the heat pipe to further absorb the heat on the heat pipe 2, and then the heat on the second section 22 is carried away by the airflow, thereby improving the heat dissipation efficiency of the second section 22 of the heat pipe.
[0056] like Figure 4-5 As shown, in some specific embodiments, the interior of the air duct 31 faces the lamp body 1, the air inlet 32 faces the lower side of the lamp body 1, the second section 22 of the heat dissipation pipe is located between the air inlet 32 and the lamp body 1, and the space between the second section 22 of the heat dissipation pipe and the lamp body 1 forms the third air outlet 35 and the fourth air outlet 36. The third air outlet 35 and the fourth air outlet 36 are located on the front and rear sides of the lamp body 1, respectively. The air entering from the air inlet 32 can be blown out from the first air outlet 33, the second air outlet 34, the third air outlet 35 and the fourth air outlet 36, respectively.
[0057] Multiple air outlets allow for even heat dissipation, preventing localized overheating and ensuring rapid heat removal. This reduces airflow short-circuiting or eddies, improving heat dissipation efficiency and reducing the number of fans required, thus lowering operating costs.
[0058] A certain space is left between the heat dissipation pipe 2 and the lamp body 1. Part of the airflow entering the air inlet 32 blows towards the second section 22 of the heat dissipation pipe, flows into this space, and flows out from the gaps on the front and rear sides between the heat dissipation pipe 2 and the lamp body 1. The gaps on the front and rear sides become the third air outlet 35 and the fourth air outlet 36 as secondary air outlets. Setting the third air outlet 35 and the fourth air outlet 36 can carry away the heat on the second section 22 of the heat dissipation pipe. The airflow flowing out from the secondary air outlets, the third air outlet 35 and the fourth air outlet 36, can dissipate heat evenly from the heat dissipation pipe 2, prevent local heat accumulation, and also reduce the amount of heat carried away by the airflow from the second section 22 of the heat dissipation pipe to the first air outlet 33 and the second air outlet 34, preventing low airflow utilization and improving heat dissipation efficiency. When the air enters the air guide shell 3 through the air inlet, the air begins to split. Due to the air duct 31 structure of the air guide shell 3, part of the air flows to the first air outlet 33, part flows to the second air outlet 34, and part blows onto the second section 22 of the heat dissipation pipe to dissipate heat. After that, it continues to flow upward. After being blocked by the lamp body 1, it flows out from the third air outlet 35 on the front side and the fourth air outlet 36 on the rear side, completing the heat dissipation process.
[0059] like Figure 10 As shown, in some specific embodiments, the vertical distance l2 between the third air outlet 35 and the fourth air outlet 36 is 6-10mm.
[0060] The vertical distance l2 between the third air outlet 35 and the fourth air outlet 36 is set to 6-10mm, which allows for a suitable airflow and improves the uniform heat dissipation effect of the air guide shell.
[0061] Since the second section 22 of the heat pipe is a secondary heat dissipation area, the vertical distance l2 of this gap can be set to 6-10mm so that the secondary air outlets formed by the third air outlet 35 and the fourth air outlet 36 can flow out a suitable airflow. If the airflow in this area is too large, it will divert the airflow on the first heat sink 4 and the second heat sink 6, resulting in uneven heat dissipation. Therefore, setting an appropriate spacing can evenly control the airflow and improve the utilization rate of wind energy.
[0062] In some specific embodiments, a sealing ring is provided between the first heat source 11 and the heat transfer seat 5.
[0063] The sealing ring can prevent dust and water, protecting the lamp body 1.
[0064] Furthermore, the first air outlet 33 covers part of the second heat sink 6, and the second air outlet 34 covers part of the first heat sink 4.
[0065] Taking the first air outlet 33 on the left as an example: the first air outlet 33 covers part of the second heat sink 6, so that part of the second heat sink 6 is exposed outside the air guide shell 3 and part is inside the air guide shell 3. The part outside the air guide shell 3 can also dissipate heat freely, thus improving the heat dissipation efficiency.
[0066] like Figure 7 As shown, in some specific embodiments, the air inlet is located on the left side of the air guide shell.
[0067] Placing the air inlet close to the primary heat source can increase the airflow directed towards the heat source, thereby improving heat dissipation efficiency.
[0068] Since the first heat source 11 is the main heat source and has a large heat dissipation requirement, the air inlet 32 can be opened near the first heat source 11 to increase the air intake near the first heat source 11, which can remove the heat of the first heat source 11 more quickly, accelerate the heat dissipation rate, and improve the heat dissipation efficiency. Correspondingly, the third heat sink can be set at the air inlet to improve the heat dissipation effect of the heat pipe.
[0069] Furthermore, the lamp body 1 includes a housing 13 and a lamp source 14. The lamp source 14 is located inside the housing 13. A fan is provided outside the air inlet 32. A temperature sensor is provided inside the housing 13. The temperature sensor is connected to a controller or control circuit that controls the fan speed.
[0070] The housing 13 can be used to protect the light source 14, the fan is used to provide airflow, and the temperature sensor allows the fan to run at a lower speed when the temperature is low, thereby reducing noise and energy consumption.
[0071] The light source 14 faces forward and has a frustum-shaped lampshade for focusing the light. A housing 13 covers the light source 14, with an opening in the part in contact with the heat source to facilitate heat transfer from the heat source to the heat pipe 2 and the heat sink. A fan is installed at the air inlet 32 to guide airflow into the air guide housing 3. Due to the structure of the air guide housing 3, the incoming airflow can evenly dissipate heat from the first heat source 11 and the second heat source 12, eliminating the need for an additional fan and reducing cooling costs.
[0072] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
