Abstract
Description
Technical Field

[0002] A laser equipment is a machine used for processing and welding materials. During the working process of the laser equipment, the laser pump will generate a large amount of heat. If the laser pump is used in a high-temperature environment for a long time, it will affect the performance of the laser equipment, thereby shortening the service life of the laser equipment. At the same time, if the performance of the laser equipment does not meet the standard, the welding requirements cannot be met. Therefore, in order to ensure the normal operation of the laser equipment, it is necessary to dissipate heat from the laser pump of the portable laser equipment and control the laser pump within a stable temperature range. Therefore, many laser equipments are equipped with a refrigeration system, and the refrigeration system is usually a chiller. The chiller can cool the laser equipment through the water circulation method to ensure that the laser equipment works normally at a constant temperature or a set temperature, reduce the thermal stress inside the laser equipment, and reduce the aging speed of the laser equipment, thereby prolonging the service life of the laser equipment.
[0003] In the prior art, due to structural limitations, some chillers have poor refrigeration effects on laser equipment, resulting in unstable working temperatures of the laser equipment, thereby affecting the light output stability of the laser equipment. Even fluctuations may occur, which may reduce the performance of the laser, such as power, beam quality, etc. Long-term high-temperature operation of the laser will accelerate the aging of its components, thereby shortening the service life of the laser.
[0004] Therefore, in order to ensure the normal operation and stable performance of the laser equipment, it is necessary to ensure that sufficient refrigeration effect can be provided within a refrigeration system with limited structure, improve the refrigeration capacity and energy efficiency of the unit, and ensure that the laser equipment works within an appropriate temperature range.

[0033] The present utility model provides a laser device with a structurally compact refrigeration system through improvement. The technical solution of the present utility model is as follows:
[0034] As Figure 1 shown, a laser device with a structurally compact refrigeration system includes:
[0035] A refrigeration system, the refrigeration system includes a compressor 11, a first condenser 12, a second condenser 13, a throttle valve 14 and an evaporator 15. The compressor 11 is connected to the first condenser 12, the first condenser 12 is connected to the second condenser 13, the second condenser 13 is connected to the throttle valve 14, the throttle valve 14 is connected to the evaporator 15, and the evaporator 15 is then connected to the compressor 11 to form a refrigeration circuit.
[0036] In the refrigeration circuit, the compressor 11 compresses the gaseous coolant at normal temperature and pressure into a gaseous coolant at high temperature and pressure. After the first condenser 12 and the second condenser 13 convert the gaseous coolant conveyed by the compressor 11 into a high-pressure liquid coolant, it is then conveyed to the throttle valve 14 for throttling and pressure reduction. After the throttle valve 14 reduces the pressure, it conveys the liquid coolant to the evaporator 15, and uses the evaporator 15 to inject water for heat exchange treatment. During the heat exchange treatment process, the evaporator 15 converts the liquid coolant into a gaseous coolant and conveys the gaseous coolant to the compressor 11 for cycle refrigeration.
[0037] In this embodiment, for a refrigeration system with limited structure, the heat transfer area on the condensing side is increased by setting up a compact second condenser 13. By connecting the first condenser 12 and the second condenser 13 in series and adjusting the arrangement order of the first condenser 12 and the second condenser 13 or the distance between the first condenser 12 and the second condenser 13, the refrigerant flow can be better controlled, which helps to ensure that each condenser operates at the best efficiency. And it can prevent uneven flow and reduce problems caused by uneven flow. Since the refrigerant flows through a longer path in the first condenser 12 and the second condenser 13, the heat exchange area can be increased and the heat exchange efficiency can be improved. Thus, the refrigerating capacity and energy efficiency of the unit are improved. Ensure the normal operation and stable performance of the laser device, ensure that sufficient refrigeration effect can be provided within the refrigeration system with limited structure, improve the refrigerating capacity and energy efficiency of the unit through the second condenser 13, ensure that the laser device works within a suitable temperature range, and increase the light output stability and service life of the laser device.
[0038] Cooling system, the cooling system includes a water tank 21, a pumping device 23 and a laser pump 22. The water tank 21 is connected to the pumping device 23, the pumping device 23 is connected to the laser pump 22, the laser pump 22 is connected to the evaporator 15, and the evaporator 15 is connected to the water tank 21 again to form a cooling loop. The pumping device 23 is used to increase the speed of the liquid in the water tank 21 being transported to the laser pump 22, so that the water tank 21 can cool or heat up the laser pump 22 faster.
[0039] In the cooling loop, the evaporator 15 is connected to the water tank 21 to store the liquid with a lower temperature in the water tank 21, and then the liquid in the water tank 21 is transported to the laser pump 22 to cool it down.
[0040] In some embodiments, the second condenser 13 is a first plate heat exchanger. The second condenser 13, which adopts a plate heat exchanger, has a high heat transfer efficiency. The flow channels of the plate heat exchanger are small, and the cross-section of the plate is complex in change, which makes the flow direction and flow velocity of the fluid constantly change, increasing the disturbance of the fluid. Therefore, the heat transfer coefficient is high.
[0041] In some embodiments, the second condenser 13 is a copper tube-aluminum fin type. The copper tube-aluminum fin type second condenser 13 enhances the heat transfer efficiency by increasing the heat dissipation area and the contact area between the fins and the tubes. In addition, the fin pitch is small and the finning coefficient is high, which can further improve the heat transfer efficiency.
[0042] In some embodiments, the second condenser 13 is a microchannel heat exchanger. The size of the microchannel is small, the flow velocity of the fluid in the channel is relatively fast, and the heat transfer efficiency is high. The microchannel heat exchanger adopts advanced manufacturing processes, reduces the waste of materials and resources, and at the same time optimizes the heat energy transfer in the fluid to achieve the purpose of saving energy.
[0043] In some embodiments, the second condenser is a section of copper pipe, which can further improve the heat transfer efficiency.
[0044] In some embodiments, the pumping device 23 is a water pump. The water pump is a DC water pump or an AC water pump. The DC brushless water pump has a low supply voltage, which can improve the safety of the laser device. Moreover, the DC brushless water pump usually uses ceramics and carbon fiber graphite bushings for mating connection, and the friction generated during use is small, so it has the characteristic of no noise. When used in conjunction with the laser device, it can further reduce the noise generated during the operation of the laser device; the AC water pump has a lower price and a longer service life, which can reduce the manufacturing cost of the laser device and extend the service life of the laser device. The DC water pump and the AC water pump each have their own advantages. Which type of water pump to choose according to specific application requirements and scenarios is not limited in this utility model.
[0045] In some embodiments, the water pump is connected to the water tank 21 through an anti-disconnection interface 231. The design of the anti-disconnection interface 231 can effectively prevent the disconnection of the pipeline connection, ensuring the stability and reliability of the pipeline connection. It can improve the stability and safety of the pipeline system of the laser device, extend the service life, and facilitate maintenance and replacement.
[0046] In some embodiments, a fan 122 is provided at the position of the first condenser 12 for air-cooled refrigeration. Using air-cooled refrigeration can accelerate the heat dissipation of the first condenser 12 or take away the cold air around the first condenser 12.
[0047] In some embodiments, the throttle valve 14 is a capillary tube, a thermostatic expansion valve or an electronic expansion valve. The capillary tube has a simple structure, no moving parts, a low price, and does not require a liquid receiver, and the amount of refrigerant charged is small. After the compressor stops, the pressure on the high and low pressure sides is easily balanced, which is beneficial to the start of the compressor; the thermostatic expansion valve controls the opening of the expansion valve according to the superheat of the gaseous coolant; the electronic expansion valve has the characteristics of a large adjustment range, rapid and sensitive action, and stability and reliability, meeting the requirements of the laser device.
[0048] In some embodiments, the compressor 11 is a DC compressor 11 or an AC compressor 11. The DC compressor 11 has the characteristics of low energy consumption, variable frequency, and easy precise control, and is suitable for use in laser devices.
[0049] In some embodiments, the evaporator 15 is a second plate heat exchanger, a titanium tube heat exchanger or a copper tube heat exchanger.
[0050] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
