Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a high-efficiency heat dissipation laser device for laser cutting machines. Background Technology

[0002] The laser in a laser cutting machine is the core component of the equipment. It converts electrical energy into a high-energy laser beam to achieve precise cutting of metallic or non-metallic materials. Its working principle involves exciting a working substance (such as CO2, optical fiber, or semiconductor) to generate laser light, which is then focused by an optical system to form a high-energy-density cutting beam. The high-energy-density laser beam is generated through stimulated emission amplification, focusing the laser energy onto the surface of the material to be cut, causing the material to melt and vaporize instantly, thus achieving high-precision cutting. Because the laser generates a large amount of heat during operation, inadequate heat dissipation will directly affect the stability of laser output, device lifespan, and cutting accuracy. Therefore, heat dissipation performance is one of the key factors determining the efficiency and reliability of a laser cutting machine.

[0003] In existing laser cutting machines, the heat generated during cutting operations is typically dissipated and regulated by air-cooling or water-sealing components. This approach often fails to effectively balance air and water cooling, resulting in relatively poor heat exchange capacity and inadequate cooling performance. Furthermore, when the laser operates under high load for extended periods, generating significant heat, the water-cooling system and fan struggle to quickly meet the cooling demands, leading to excessively high localized laser temperatures. This not only reduces the stability and efficiency of laser output but also accelerates the aging of internal components, shortening their lifespan. Additionally, the system cannot effectively regulate heat exchange and cooling intensity based on the laser's heating temperature, resulting in insufficient continuous and stable operation of the laser cutting equipment. Therefore, we propose a high-efficiency heat dissipation laser device for laser cutting machines to address these issues. Utility Model Content

[0010] Preferably, the circulation guide assembly includes two circulation guide pipes, a circulation pump body, and a control switch valve. The tops of the two circulation guide pipes are connected to the liquid storage tank. The output end of the circulation pump body is connected to the circulation guide pipe.

The two circulation guide pipes circulate between the liquid storage tank and the water-cooled heat exchange assembly. The two control switch valves are respectively installed on the two circulation guide pipes.

[0011] Preferably, the bottom of the liquid storage tank is provided with pipe connection ends on both sides, and the top ends of the two flow circulation pipes are respectively installed and sealed on the two pipe connection ends.

The output end of the temperature detection controller is electrically connected to the input end of the micro pump.

[0013] Preferably, the spray atomizing nozzle is located on the side of the waterproof fan, and the two waterproof fans blow air in the same direction.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. The laser device of this high-efficiency heat dissipation laser cutting machine has a water-cooled heat exchange component installed on the outer side of the laser end of the laser cutter body, and a liquid storage tank on the side. The liquid storage tank forms a cooling cycle with the circulation guide component and the water-cooled heat exchange component. The circulation guide component can export the coolant in the liquid storage tank. When it flows through the water-cooled heat exchange component, it exchanges heat with the heat generated at the cutting end of the laser cutter body, achieving water cooling. The water source exported by the water-cooled heat exchange component can be redirected back into the liquid storage tank to form a water cooling cycle, and the water cooling is stable.

[0017] 2. The laser device of this high-efficiency heat dissipation laser cutting machine has an atomizing air-cooling component installed on the side of the liquid storage tank. The atomizing air-cooling component acts as a blower for cooling the main body of the laser cutter. At the same time, water in the liquid storage tank can be extracted and atomized and sprayed. The atomized water absorbs a large amount of heat during the evaporation process, which in turn rapidly cools the air blown out by the atomizing air-cooling component, thus completing the air-cooling heat dissipation and cooling effect. The main body of the laser cutter can be cooled by both air and water simultaneously, with good heat dissipation and cooling effect, so that the device combines the heat exchange capacity of water cooling and air cooling.

[0018] 3. The laser device of this high-efficiency heat dissipation laser cutting machine can monitor the temperature and control the switching of the circulation guide component and the atomizing air cooling component simultaneously through the temperature detection controller. When the temperature of the laser cutter body is low, only the circulation guide component or the atomizing air cooling component needs to be operated. When the temperature inside the laser cutter body is high, the temperature detection controller controls the simultaneous activation of air cooling and water cooling to improve heat dissipation efficiency. This allows the laser cutting equipment to adjust the heat dissipation intensity according to temperature changes, resulting in excellent heat dissipation and stable equipment operation.

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Please see Figures 1-6 A high-efficiency heat dissipation laser cutting machine laser device includes a laser cutter body 1, and a liquid storage tank 2 is provided on the side of the laser cutter body 1.

[0029] A water-cooled heat exchange component 3 is provided on the outer side of the laser tip of the laser cutter body 1. A circulation guide component 4 is connected between the liquid storage tank 2 and the water-cooled heat exchange component 3. An atomizing air-cooling component 5 connected to the liquid storage tank 2 is provided on the outer side of the laser cutter body 1. A temperature detection controller 6 is provided on the side of the laser cutter body 1.

[0030] The beneficial effects of this solution are as follows: By operating the circulation guide component 4, the coolant in the storage tank 2 can be exported. When it flows through the water-cooled heat exchange component 3, it exchanges heat with the heat generated at the cutting end of the laser cutter body 1, achieving water cooling. The water exported by the water-cooled heat exchange component 3 can be redirected back into the storage tank 2 to form a water cooling cycle. The atomized air-cooling component 5 acts as a blower for the laser cutter body 1. At the same time, the water in the storage tank 2 can be extracted and atomized and sprayed. The atomized water absorbs a large amount of heat during the evaporation process, which can then quickly cool the air blown out by the atomized air-cooling component 5, thus completing the air cooling effect. It can perform both air cooling and water cooling, resulting in good heat dissipation and cooling effect.

[0031] The temperature detection controller 6 can monitor the temperature and simultaneously control the switching of the circulation guide component 4 and the atomizing air-cooling component 5. When the temperature inside the laser cutter body 1 is high, the temperature detection controller 6 controls the simultaneous activation of air cooling and water cooling to improve heat dissipation efficiency and ensure stable operation. This allows the device to balance water cooling heat exchange and air cooling capabilities, resulting in excellent heat dissipation and cooling capacity. Furthermore, the heat dissipation intensity can be adjusted according to temperature changes, ensuring excellent heat dissipation function and stable equipment operation.

[0032] Furthermore, the liquid storage tank 2, the water-cooled heat exchange component 3 and the circulation guide component 4 are connected in an integrated circulation system. The liquid storage tank 2 is equipped with a liquid level alarm 21 and is mounted on the main body 1 of the laser cutter.

[0033] Specifically, the liquid storage tank 2, the water-cooled heat exchange component 3, and the circulation guide component 4 are integrated and interconnected, which makes the water-cooled circulation guide of the device stable and convenient to operate. In addition, the liquid level alarm 21 can be set up to alarm when the water level in the liquid storage tank 2 is insufficient, preventing the device from running dry when the water source is insufficient, and ensuring stable operation.

[0034] Furthermore, the water-cooled heat exchange component 3 includes a threaded heat exchange tube 31, a circulation mounting end 32, and heat dissipation fins 33. The threaded heat exchange tube 31 is sleeved and attached to the outside of the laser end of the laser cutter body 1. The two circulation mounting ends 32 are connected and installed at both ends of the threaded heat exchange tube 31. Two or more heat dissipation fins 33 are installed in a ring at equal intervals on the outside of the threaded heat exchange tube 31. The threaded heat exchange tube 31 is flat. The top ends of the threaded heat exchange tube 31 and the circulation mounting end 32 are connected to the circulation guide component 4.

[0035] Specifically, the spiral heat exchange tube 31 is spirally sleeved on the outside of the laser end of the laser cutter body 1. When the coolant flows through the spiral heat exchange tube 31, it can quickly exchange heat with the laser cutting equipment, and the heat exchange is stable. Heat dissipation fins 33 are evenly arranged on the outside of the spiral heat exchange tube 31, which greatly improves the heating area and heat dissipation area. While facilitating water cooling, it can also be stably cooled by the atomized air cooling component 5, with good heat dissipation effect. Both ends of the spiral heat exchange tube 31 are equipped with circulation installation ends 32. The two circulation installation ends 32 can be connected to the two ends of the circulation guide component 4 respectively, so that the entire spiral heat exchange tube 31 can perform water cooling circulation guide operation, and the water cooling circulation is stable.

[0036] Furthermore, the circulation guide assembly 4 includes two circulation guide pipes 41, a circulation pump body 42, and a control switch valve 43. The tops of the two circulation guide pipes 41 are connected to the liquid storage tank 2. The output end of the circulation pump body 42 is connected to the circulation guide pipes 41. The bottoms of the two circulation guide pipes 41 are respectively connected to the top two ends of the water-cooled heat exchange assembly 3. The two circulation guide pipes 41 circulate between the liquid storage tank 2 and the water-cooled heat exchange assembly 3. The two control switch valves 43 are respectively installed on the two circulation guide pipes 41. The output end of the temperature detection controller 6 is electrically connected to the input end of the circulation pump body 42.

[0037] Specifically, the two flow circulation pipes 41 can circulate between the liquid storage tank 2 and the water-cooled heat exchange component 3. The flow pump body 42 pressurizes and discharges the water source through the flow circulation pipe 41, and then the water source is reintroduced through the other flow circulation pipe 41 to form a water-cooled circulation flow operation. The control valve 43 plays a switching control role, which is highly practical.

[0038] Furthermore, pipe connection ends 22 are installed on both sides of the bottom of the liquid storage tank 2, and the top ends of the two flow circulation pipes 41 are respectively installed and sealed on the two pipe connection ends 22. The flow circulation pipes 41 are connected to the liquid storage tank 2 through the pipe connection ends 22.

[0039] Specifically, the pipe connection end 22 facilitates the connection of the flow circulation pipe 41 to the liquid storage tank 2, making installation and operation convenient and disassembly easy.

[0040] Furthermore, the atomizing air-cooling assembly 5 includes a mounting bracket 51, a waterproof fan 52, a spray atomizing pipe 53, a spray atomizing nozzle 54, and a micro pump body 55. The mounting bracket 51 is installed on both sides of the laser cutter body 1. The two waterproof fans 52 are installed on the bottom of the two mounting brackets 51. The top of the spray atomizing pipe 53 is connected to the bottom of the liquid storage tank 2. The spray atomizing nozzle 54 is installed and fixed on the bottom of the spray atomizing pipe 53. The airflow direction of the two waterproof fans 52 is set on both sides of the laser end of the laser cutter body 1. The output end of the micro pump body 55 is connected to the spray atomizing pipe 53. The micro pump body 55 is installed on the side of the mounting bracket 51. The output end of the temperature detection controller 6 is electrically connected to the input end of the micro pump body 55.

[0041] Specifically, the mounting bracket 51 can support the waterproof fan 52. The two waterproof fans 52 are respectively set on both sides of the laser end of the laser cutter body 1, and can perform air cooling blowing operations. The spray atomizing pipe 53, together with the micro pump body 55, can pressurize and guide the water source in the liquid storage tank 2 out, and then perform atomization spraying operations by the spray atomizing nozzle 54. The atomized gas plays a heat absorption role when evaporating, which can significantly reduce the blowing and heat dissipation capacity of the waterproof fan 52.

[0042] Furthermore, the spray atomizing nozzle 54 is located on the side of the waterproof fan 52, and the two waterproof fans 52 blow air in the same direction;

[0043] Specifically, two waterproof fans 52 blow air in the same direction. One of them blows cool air containing water vapor to the laser tip of the laser cutter body 1 for heat dissipation and cooling, while the other guides and discharges excess water vapor, so that the water vapor blowing is stable and the amount of water vapor is kept small. While the air blowing is stable, the water vapor is not easy to spread, and the laser cutting operation is stable.

[0044] Furthermore, the temperature detection controller 6 includes a temperature detector 61 and a switch controller 62. The temperature detector 61 is installed on the side of the laser cutter body 1. The switch controller 62 is electrically connected to the circulation guide assembly 4 and the atomizing air cooling assembly 5 respectively. The output terminal of the temperature detector 61 is electrically connected to the input terminal of the switch controller 62.

[0045] Specifically, the temperature detector 61 can stably measure the temperature of the laser cutter body 1. When the temperature of the laser cutter body 1 is too high, the switch controller 62 can operate and control the circulation guide component 4 and the atomizing air cooling component 5. When the temperature of the laser cutter body 1 is low, only the circulation guide component 4 or the atomizing air cooling component 5 needs to be operated. When the temperature inside the laser cutter body 1 is high, the temperature detection controller 6 controls the simultaneous activation of air cooling and water cooling to improve heat dissipation efficiency and ensure that the laser cutting equipment can always maintain a stable temperature and adapt to stability.

[0046] How to use and how to work this device:

[0047] A water-cooled heat exchange component 3 is provided on the outer side of the laser end of the laser cutter body 1, and a liquid storage tank 2 is provided on the side. The liquid storage tank 2 forms a cooling cycle with the circulation guide component 4 and the water-cooled heat exchange component 3. The circulation guide component 4 can export the coolant in the liquid storage tank 2. When it flows through the water-cooled heat exchange component 3, it exchanges heat with the heat generated at the cutting end of the laser cutter body 1 to achieve water cooling. The water source exported by the water-cooled heat exchange component 3 can be redirected back into the liquid storage tank 2 to form a water cooling cycle. The water cooling is stable.

[0048] The side of the liquid storage tank 2 is equipped with an atomizing air-cooling component 5. The atomizing air-cooling component 5 acts as a blower for the laser cutter body 1. At the same time, the water in the liquid storage tank 2 can be extracted and atomized and sprayed. The atomized water absorbs a lot of heat during the evaporation process, which can quickly cool the air blown out by the atomizing air-cooling component 5, thus completing the air-cooling heat dissipation and cooling effect. The laser cutter body 1 can be cooled by both air and water at the same time, resulting in a good heat dissipation and cooling effect.

[0049] A temperature detection controller 6 is provided on the side of the laser cutter body 1. It can monitor the temperature and control the switching of the circulation guide component 4 and the atomizing air cooling component 5. When the temperature of the laser cutter body 1 is low, only the circulation guide component 4 or the atomizing air cooling component 5 needs to be operated. When the temperature inside the laser cutter body 1 is high, the temperature detection controller 6 controls the simultaneous activation of air cooling and water cooling to improve heat dissipation efficiency and ensure that the laser cutting equipment can always maintain a stable temperature and adapt to stability.

[0050] The water-cooled heat exchange component 3 includes a threaded heat exchange tube 31, a circulation mounting end 32, and heat dissipation fins 33. The threaded heat exchange tube 31 is spirally sleeved on the outside of the laser end of the laser cutter body 1. When the coolant flows through the threaded heat exchange tube 31, it can quickly exchange heat with the laser cutting equipment and the heat exchange is stable. Heat dissipation fins 33 are evenly arranged on the outside of the threaded heat exchange tube 31, which greatly increases the heat receiving area and heat dissipation area. While facilitating water cooling, it can also be stably cooled by the atomized air cooling component 5, resulting in good heat dissipation. Both ends of the threaded heat exchange tube 31 are equipped with circulation mounting ends 32. The two circulation mounting ends 32 can be connected to the two ends of the circulation guide component 4 respectively, so that the entire threaded heat exchange tube 31 can perform water cooling circulation guide operation and the water cooling circulation is stable.

[0051] The circulation guide assembly 4 includes two circulation guide pipes 41, a flow guide pump body 42, and a control switch valve 43. The two circulation guide pipes 41 can circulate and connect the liquid storage tank 2 and the water-cooled heat exchange assembly 3. The flow guide pump body 42 pressurizes and discharges water from the circulation guide pipe 41, and then discharges water back into the system through the other circulation guide pipe 41, forming a water-cooled circulation guide operation. The control switch valve 43 plays a switching control role, making it highly practical.

[0052] The atomizing air-cooling component 5 includes a mounting frame 51, a waterproof fan 52, a spray atomizing pipe 53, a spray atomizing nozzle 54, and a micro pump body 55. The mounting frame 51 can support the waterproof fan 52. The two waterproof fans 52 are respectively set on both sides of the laser end of the laser cutter body 1, and can perform air-cooling blowing operations. The spray atomizing pipe 53, together with the micro pump body 55, can pressurize and guide the water source in the liquid storage tank 2 out, and then perform atomization spraying operations by the spray atomizing nozzle 54. The atomized gas plays a heat absorption role when evaporating, which can significantly reduce the blowing and heat dissipation capacity of the waterproof fan 52. At the same time, the two waterproof fans 52 blow air in the same direction. One of them blows the cold air with water vapor to the laser end of the laser cutter body 1 for heat dissipation and cooling, and the other guides and discharges the excess water vapor, so that the water vapor blowing is stable and the water vapor volume is kept small. While the blowing is stable, the water vapor is not easy to spread, and the laser cutting operation is stable.

[0053] This device can combine water-cooled heat exchange and air-cooled heat dissipation capabilities, has excellent heat dissipation and cooling capacity, and can adjust the heat dissipation intensity according to temperature changes, resulting in excellent heat dissipation function and stable equipment operation.
