Description

Technical Field

[0001] This utility model relates to the technical field of laser heating and cooling devices, specifically a laser heating and cooling device. Background Technology

[0002] As industrial manufacturing upgrades towards higher precision and higher power, laser technology has deeply penetrated into key areas such as welding of aerospace components, cutting of semiconductor chips, and precise ablation of tumors in medical treatment. The core advantage of laser equipment lies in its concentrated energy density and processing precision down to the micrometer level. However, this characteristic is also accompanied by a serious heat problem. When the laser generator is running continuously, the heat generated by the internal electronic components will accumulate and rise. If the heat dissipation is not timely, it can easily cause damage to the equipment.

[0003] Currently, laser generators are mainly cooled by air cooling, water cooling, or a combination of both. For example, a Chinese patent with publication number CN214100227U discloses a laser source heat dissipation device. It uses coolant to be poured into the cooling module through the coolant inlet, flows through the spiral groove, and then flows out of the coolant outlet to the heat dissipation module for cooling. After that, the coolant is put back into the cooling module through the coolant delivery pipe. This cycle is repeated to dissipate heat from the laser source. The cooling module is fitted around the laser source and has spiral grooves in it. Coolant is poured into the spiral grooves. Compared with the method of wrapping copper pipes around the heating element, this method increases the heat conduction area, improves the heat conduction efficiency, accelerates the heat dissipation speed, has a simpler structure, and is easier to install.

[0004] In the aforementioned literature, existing laser source heat dissipation devices require modifications to the structure of the laser generating module during use. These modifications increase production costs, and the existing laser source heat dissipation devices are inconvenient to disassemble, making it difficult to repair or replace the laser generating module and affecting production efficiency. Therefore, a laser heat dissipation cooling device is proposed to address these issues. Utility Model Content

[0005] To address the shortcomings of existing technologies, specifically the issues that existing mobile shelving systems can only handle goods in one direction and that improper handling during the storage and retrieval of high-level goods can easily lead to goods tipping over and falling, posing a safety hazard, this utility model proposes a laser heating and cooling device.

[0006] The technical solution adopted by this utility model to solve its technical problem is: the laser heating and cooling device of this utility model includes a substrate, two cooling components are mirror-arranged on the substrate, a laser generator body is arranged on the substrate, and the laser generator body is located between the two cooling components.

[0007] Two centering components are disposed under the substrate, and the functional ends of the two centering components are respectively connected to the two sides of the two cooling components.

[0008] The cooling assembly includes an L-shaped fixing plate, on the inner side of which a high thermal conductivity silicone rubber pad is fixed. The high thermal conductivity silicone rubber pads in the two cooling assemblies are symmetrically attached to both sides of the laser generator body. On the side of the L-shaped fixing plate opposite to the laser generator body, a uniformly distributed heat dissipation fin is fixed. Multiple L-shaped delivery tubes are fixed through the heat dissipation fins. A uniformly distributed guide groove is opened through the substrate. The bottom ends of the L-shaped delivery tubes are respectively installed in the guide grooves and are fixed together to a liquid storage box.

[0009] Preferably, the heat dissipation fins are arranged longitudinally, the guide grooves are arranged transversely, the ends of adjacent L-shaped conveying pipes are jointly fixed with a return bend, and the return bend is fixed on the horizontal section of the L-shaped fixing plate. The ends of adjacent L-shaped conveying pipes located in the liquid storage box are jointly fixed with a cooling bend, and the cooling bend and the return bend are staggered.

[0010] Preferably, the multiple L-shaped conveying pipes are connected by multiple return bends and multiple cooling bends. The two outermost L-shaped conveying pipes are respectively provided with an inlet pipe and a drain pipe. A conveying pump is fixed on the L-shaped conveying pipe with the drain pipe. A refrigeration module is fixed on the side wall of the liquid storage box, and the working end of the refrigeration module extends into the liquid storage box.

[0011] Preferably, guide strips are fixed on both sides of the multiple guide groove openings at the lower part of the substrate, a sliding plate is slidably disposed on each L-shaped conveying pipe, and the sliding plate is slidably disposed between two corresponding guide strips. A first spring is sleeved on each L-shaped conveying pipe, and the first spring is located between the sliding plate and the liquid storage box.

[0012] Preferably, the centering assembly includes two side plates, with two limiting rods fixedly connected between the two side plates by a fixing strip, and two sliding blocks slidably disposed on the two limiting rods, with the same end of the two liquid storage boxes respectively fixedly connected to the two sliding blocks.

[0013] Preferably, two second springs are respectively fitted on the two limiting rods, and the second springs are located between the sliding block and the side plate, and both limiting rods are parallel to the guide groove.

[0014] Preferably, a fan is fixed on the substrate, and the fan is located on the side opposite to the working end of the laser generator body. The driving end of the fan is connected to a motor, and the motor is fixed on the outer casing of the fan.

[0015] The advantages of this utility model are:

[0016] 1. This utility model expands the L-shaped fixing plate by pulling it, and releases the clamping and fixing of the laser generator body by using the liquid storage box and the sliding block to squeeze the first and second springs respectively. This facilitates the inspection and replacement of the laser generator body and avoids the increase in production costs caused by modifying the original module structure.

[0017] 2. This utility model uses a motor to drive a fan, increasing the airflow speed on the surface of multiple heat dissipation fins and the laser generator body. This allows the refrigerant to be transported along the arrangement of multiple L-shaped delivery pipes. When the refrigerant flows into the cooling bend, it will be cooled again using the refrigerant in the liquid storage box to improve the cooling effect. In conjunction with the low-temperature refrigerant circulating in the heat dissipation fins to cool the L-shaped fixing plate, the L-shaped fixing plate and the high thermal conductivity silicone rubber gasket exchange heat with the laser generator body, thereby achieving a combined liquid cooling and air cooling effect on the laser generator body.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] Please see Figure 1-5 As shown, a laser heating and cooling device includes a substrate 1, on which two cooling components 2 are mirror-arranged, and a laser generator body 11 is disposed on the substrate 1, with the laser generator body 11 located between the two cooling components 2.

[0030] Two centering components 3 are disposed under the substrate 1, and the functional ends of the two centering components 3 are respectively connected to the two sides of the two cooling components 2.

[0031] The cooling assembly 2 includes an L-shaped fixing plate 21. A high thermal conductivity silicone rubber pad 24 is fixed inside the L-shaped fixing plate 21. The high thermal conductivity silicone rubber pads 24 in the two cooling assemblies 2 are symmetrically attached to both sides of the laser generator body 11. A uniformly distributed heat dissipation fin 22 is fixed to the side of the L-shaped fixing plate 21 opposite to the laser generator body 11. A plurality of L-shaped delivery pipes 23 are fixed through the heat dissipation fins 22. A uniformly distributed guide groove 214 is opened through the substrate 1. The bottom ends of the L-shaped delivery pipes 23 are respectively installed in the guide grooves 214 and are fixed together to a liquid storage box 26.

[0032] The heat dissipation fins 22 are arranged longitudinally, the guide grooves 214 are arranged laterally, the ends of adjacent L-shaped conveying pipes 23 are jointly fixed with a return bend 25, and the return bend 25 is fixed on the horizontal section of the L-shaped fixing plate 21. The ends of adjacent L-shaped conveying pipes 23 located in the liquid storage box 26 are jointly fixed with a cooling bend 27, and the cooling bend 27 and the return bend 25 are staggered.

[0033] Multiple L-shaped delivery pipes 23 are connected by multiple return bends 25 and multiple cooling bends 27. The two outermost L-shaped delivery pipes 23 are respectively provided with a liquid inlet pipe 28 and a liquid extraction pipe 29. A delivery pump 210 is fixed on the L-shaped delivery pipe 23 with the liquid extraction pipe 29. A refrigeration module 215 is fixed on the side wall of the liquid storage box 26, and the working end of the refrigeration module 215 extends into the liquid storage box 26.

[0034] Guide strips 211 are fixed on both sides of the openings of multiple guide grooves 214 at the lower part of the substrate 1. A sliding plate 212 is slidably disposed on each of the L-shaped delivery pipes 23, and the sliding plate 212 is slidably disposed between two corresponding guide strips 211. A first spring 213 is sleeved on each of the L-shaped delivery pipes 23, and the first spring 213 is located between the sliding plate 212 and the liquid storage box 26.

[0035] The centering component 3 includes two side plates 31, and two limiting rods 32 are fixedly connected between the two side plates 31. Two sliding blocks 33 are slidably arranged on the two limiting rods 32, and the same side end of the two liquid storage boxes 26 is respectively fixed to the two sliding blocks 33.

[0036] Two second springs 34 are respectively sleeved on the two limiting rods 32, and the second springs 34 are located between the sliding block 33 and the side plate 31. Both limiting rods 32 are parallel to the guide groove 214.

[0037] A fan 4 is fixed on the substrate 1, and the fan 4 is located on the side opposite to the working end of the laser generator body 11. The driving end of the fan 4 is connected to a motor 41, and the motor 41 is fixed on the outer shell of the fan 4.

[0038] During operation, the existing laser source heat dissipation device requires modification of the structure of the laser generating module, which increases production costs. Furthermore, the existing laser source heat dissipation device is inconvenient to disassemble, making it difficult to repair or replace the laser generating module and affecting production efficiency. In this solution, in the initial state, the first spring 213 will always push the liquid storage box 26 downward, causing the liquid storage box 26 to drive multiple L-shaped delivery pipes 23 to extend towards the lower side of the substrate 1. This will cause the horizontal sections of the L-shaped fixing plates 21 in the two cooling components 2 to adhere to the top of the laser generator body 11. The second spring 34 located at both ends of the limiting rod 32 will always push the sliding block 33 inward, so that the sliding blocks 33 in the two centering components 3 will simultaneously drive the liquid storage boxes 26 in the two cooling components 2 to move inward. This will allow the vertical sections of the L-shaped fixing plates 21 in the two cooling components 2 to adhere to the sides of the laser generator body 11, achieving the centering and clamping function.

[0039] In use, by moving the L-shaped fixing plates 21 inside the two cooling components 2 to both sides, the multiple L-shaped conveying pipes 23 and multiple heat dissipation fins 22 fix the L-shaped fixing plates 21, causing the L-shaped fixing plates 21 to drive the multiple L-shaped conveying pipes 23 to slide in the multiple guide grooves 214 respectively. When the L-shaped conveying pipes 23 slide in the guide grooves 214, they will drive the sliding plate 212 to slide between the corresponding two guide bars 211. After the two L-shaped fixing plates 21 expand, the L-shaped fixing plates 21 inside the two cooling components 2 are pulled upward to drive the multiple L-shaped conveying pipes 23 to extend towards the base plate 1. When the L-shaped conveying pipes 23 extend upward, they will drive the liquid storage box 26 to compress the first spring 213 upward and contract it. After the spring 213 retracts, the distance between the horizontal section of the L-shaped fixing plate 21 and the surface of the substrate 1 will increase. Then, the laser generator body 11 can be placed on the substrate 1. After the L-shaped fixing plate 21 is released, under the action of the first spring 213 and the second spring 34, the L-shaped fixing plate 21 will re-attach to the outside of the laser generator body 11. The horizontal sections of the L-shaped fixing plates 21 in the two cooling components 2 are symmetrically arranged on the upper part of the laser generator body 11, while the vertical sections of the two L-shaped fixing plates 21 will respectively attach to the two opposite sides of the laser generator body 11. Under the action of the high thermal conductivity silicone rubber pad 24, it can tightly attach to the surface of the laser generator body 11, fill the tiny gaps, and reduce the contact thermal resistance.

[0040] During cooling, the heat dissipation area of ​​the laser generator body 11 is increased by the action of multiple heat dissipation fins 22, and the fan 4 is driven by the motor 41 to increase the airflow speed on the surface of the multiple heat dissipation fins 22 and the laser generator body 11, thereby achieving air cooling. When the cooling module 215 is running, it cools the refrigerant in the liquid storage box 26. In conjunction with the operation of the control pump 210, the pump 210 pumps the refrigerant in the liquid storage box 26 into the L-shaped delivery pipe 23 through the liquid extraction pipe 29 for delivery. The refrigerant is also delivered through the return bend 25 and the cooling bend. Under the action of 27, multiple L-shaped delivery pipes 23 form a passage, allowing the refrigerant to be delivered along the arrangement direction of multiple L-shaped delivery pipes 23. Finally, it flows back into the liquid storage box 26 through the liquid extraction pipe 29 for circulation. When the cooler flows into the cooling bend 27, it will use the refrigerant in the liquid storage box 26 to cool down again. In conjunction with the use of low-temperature refrigerant circulating in the heat dissipation fins 22 to cool the L-shaped fixing plate 21, and the L-shaped fixing plate 21 and the high thermal conductivity silicone rubber gasket 24 are used to exchange heat with the laser generator body 11, so as to achieve the liquid cooling effect of the laser generator body 11.

[0041] When the laser generator body 11 needs to be inspected or replaced, the L-shaped fixing plate 21 is pulled again to expand it. The liquid storage box 26 and the sliding block 33 are used to squeeze the first spring 213 and the second spring 34 to retract, which releases the clamping and fixing of the laser generator body 11. This makes it easier to inspect and replace the laser generator body 11 and avoids the need to modify the original module structure, which would increase production costs.

[0042] It effectively cools the laser generator, making it easier to disassemble and reassemble the laser generator compared to traditional cooling devices. This significantly improves maintenance convenience and avoids the increased costs associated with modifying the original module structure.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
