Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for laser equipment, specifically to a heat dissipation auxiliary device adapted to a surface-emitting laser projection device. Background Technology

[0002] Surface-emitting laser projection devices are widely used in laser display, 3D sensing, and industrial inspection due to their good beam uniformity and high integration. However, the core light-emitting unit (such as VCSEL array) of such devices generates a lot of heat when operating at high power.

[0003] Existing heat dissipation components are mostly fixedly connected to the laser housing (such as by welding or riveting), which requires destructive disassembly for later maintenance, resulting in high maintenance costs and long cycles. Furthermore, the compatibility of single air cooling or liquid cooling methods is low, and the heat dissipation efficiency is low. Utility Model Content

[0004] Therefore, this utility model provides a heat dissipation auxiliary device adapted to a surface-emitting laser projection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation auxiliary device adapted to a surface-emitting laser projection device, comprising a laser housing, a heat dissipation shell at the bottom of the laser housing, a heat dissipation component inside the heat dissipation shell, and limiting components on both sides of the heat dissipation shell;

Detailed Implementation

[0028] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] See attached document Figure 1 - Appendix Figure 9The present invention provides a heat dissipation auxiliary device adapted to a surface-emitting laser projection device, including a laser housing 1, a heat dissipation shell 2 at the bottom of the laser housing 1, a heat dissipation component inside the heat dissipation shell 2, and limiting components on both sides of the heat dissipation shell 2.

[0030] The heat dissipation assembly includes multiple retaining frames 17, with a heat-conducting plate 15 inserted inside each retaining frame 17. Multiple heat-conducting pipes 16 are installed on one side of the heat-conducting plate 15. Both the output and input ends of the multiple heat-conducting pipes 16 are connected to retaining cases 11. A connector 12 is installed on one side of the retaining case 11. Two retaining slots 18 are opened on one side of the heat dissipation housing 2. The retaining slots 18 are engaged with the retaining cases 11. A fan assembly is provided on one side of the heat dissipation housing 2. The fan assembly includes a cylinder 8. A second ventilation mesh plate 9 is fixedly provided on one side of the cylinder 8. A motor 10 is installed on one side of the second ventilation mesh plate 9. A fan blade 20 is connected to the output end of the motor 10. A first ventilation mesh plate 3 is installed on the side of the heat dissipation housing 2 away from the fan assembly.

[0031] In this embodiment, during operation, the heat generated by the surface-emitting laser module is transferred to the heat-conducting plate 15 through the heat-conducting pad 13 (the flexible properties of the heat-conducting pad 13 can fill the micro gaps on the contact surface, reducing thermal resistance), and then dispersed by the heat-conducting plate 15 to multiple heat-conducting pipes 16. At this time, the external coolant enters the housing 11 through one of the connectors 12, circulates through the heat-conducting pipes 16, and flows out from the other connector 12. At the same time, the motor 10 is started to drive the fan blades 20 to rotate, forming an airflow path from the second ventilation mesh plate 9, through the heat dissipation housing 2 to remove the heat from the surface of the heat-conducting plate 15 and the heat-conducting pipes 16, and finally out from the first ventilation mesh plate 3, realizing the coordinated heat dissipation of liquid cooling and air cooling.

[0032] In order to achieve the purpose of heat conduction, the device adopts the following technical solution: the top of the heat conduction plate 15 is provided with a heat conduction pad 13, the heat conduction pad 13 is located inside the heat dissipation shell 2, and the heat conduction pad 13 is made of high elastic silicone material to ensure tight contact with the surface emission laser module.

[0033] In order to achieve heat dissipation, the device adopts the following technical solution: the bottom of the laser housing 1 is provided with multiple bottom grooves 19. The design of the bottom grooves 19 provides additional ventilation space for the bottom of the heat dissipation housing 2, so as to avoid heat accumulation at the bottom of the device.

[0034] To achieve the installation purpose, this device adopts the following technical solution: An inner sliding groove 7 is provided inside the laser housing 1; multiple sliders 14 are fixedly provided on both sides of the heat dissipation housing 2, and the sliders 14 slide inside the inner sliding groove 7. Two limiting grooves 28 are provided inside the inner sliding groove 7; side grooves 4 are provided on both sides of the laser housing 1; the limiting assembly includes a side housing 5, which is fixedly connected to the heat dissipation housing 2; a push block 22 is provided inside the side housing 5; a threaded rod 21 is fixedly connected to one side of the push block 22; the threaded rod 21 extends out of the side housing 5 and is threadedly connected to the connection point of the side housing 5; a knob 6 is fixedly connected to one end of the threaded rod 21; through grooves 23 are provided on both sides of the side housing 5; two connecting plates 24 are provided inside the side housing 5; the connecting plates 24 and... The push block 22 contacts each other. A locking block 25 is fixedly provided on one side of the connecting plate 24. The locking block 25 passes through the through groove 23. Two telescopic rods 26 are fixedly provided on one side of the connecting plate 24. The telescopic rods 26 are fixedly connected to the inner wall of the side shell 5. A spring 27 is sleeved on the outside of the telescopic rods 26. The sliders 14 on both sides of the heat dissipation shell 2 are aligned with the inner sliding groove 7 on the inner side of the laser shell 1 and pushed in along the groove to the bottom. At this time, the operator can put his hand into the side grooves 4 on both sides of the laser shell 1 and rotate the knob 6 to drive the threaded rod 21 to rotate. Since the threaded rod 21 is connected to the side shell 5 by threads, its axial movement will push the push block 22 to squeeze the connecting plate 24, so that the connecting plate 24 overcomes the elastic force of the spring 27 and moves outward along the telescopic rod 26. Finally, the locking block 25 passes through the through groove 23 and is locked into the limiting groove 28 of the inner sliding groove 7, thus completing the fixation of the heat dissipation shell 2.

[0035] The usage process of this utility model is as follows: During the installation stage, the modular assembly of the heat dissipation component is completed first. The heat conduction plate 15 is inserted into the card frame 17. Then, multiple heat conduction pipes 16 are inserted into the grooves on the side of the heat conduction plate 15, so that the input end and output end of the heat conduction pipe 16 are respectively connected to the card case 11. Then, the card case 11 is fastened into the card slot 18 of the heat dissipation housing 2. Finally, a heat conduction pad 13 (made of high elastic silicone material to ensure tight contact with the surface-emitting laser module) is laid on the top of the heat conduction plate 15.

[0036] Next, the heat sink housing 2 is connected to the laser housing 1. The sliders 14 on both sides of the heat sink housing 2 are aligned with the inner sliding groove 7 on the inner side of the laser housing 1 and pushed in along the groove to the bottom. At this time, the operator can put his hand into the side grooves 4 on both sides of the laser housing 1 and rotate the knob 6 to drive the threaded rod 21 to rotate. Since the threaded rod 21 is connected to the side housing 5 by threads, its axial movement will push the push block 22 to squeeze the connecting plate 24, so that the connecting plate 24 overcomes the elastic force of the spring 27 and moves outward along the telescopic rod 26. Finally, the locking block 25 passes through the through groove 23 and is locked into the limiting groove 28 of the inner sliding groove 7, thus completing the fixing of the heat sink housing 2.

[0037] During operation, the heat generated by the surface-emitting laser module is transferred to the heat-conducting plate 15 through the heat-conducting pad 13 (the flexible properties of the heat-conducting pad 13 can fill the micro gaps on the contact surface, reducing thermal resistance), and then dispersed by the heat-conducting plate 15 to multiple heat-conducting pipes 16. At this time, the external coolant enters the housing 11 through one of the connectors 12, circulates through the heat-conducting pipes 16, and flows out from the other connector 12. At the same time, the motor 10 is started to drive the fan blades 20 to rotate, forming an airflow path from the second ventilation mesh plate 9, through the heat dissipation housing 2 to remove the heat from the surface of the heat-conducting plate 15 and the heat-conducting pipes 16, and finally out from the first ventilation mesh plate 3, realizing the coordinated heat dissipation of liquid cooling and air cooling.

[0038] When maintenance or replacement of the heat dissipation components is required, rotate the knob 6 in the opposite direction. The push block 22 releases the pressure on the connecting plate 24, and the spring 27 resets, causing the locking block 25 to retract into the through groove 23. The heat dissipation housing 2 can then be pulled out along the inner slide groove 7. Subsequently, the locking shell 11, heat conduction pipe 16, or heat conduction plate 15 can be disassembled separately for maintenance. The design of the bottom groove 19 provides additional ventilation space at the bottom of the heat dissipation housing 2, preventing heat from accumulating at the bottom of the device.

[0039] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
