Description

Technical Field

[0001] The present application relates to the field of laser technology, and in particular to a refrigeration system and a laser. Background Art

[0002] Existing lasers usually need to cool the pump source or other heat generating devices through a cooling system. Since the laser frequently switches between emitting light and stopping light during use, the pump source and the heat generating device also frequently switch between the running state and the stopped state. The cooling system needs to maintain normal operation to avoid the cooling system being unable to cool the heat generating device in time when the heat generating device switches from the stopped state to the running state.

[0003] In order to reduce energy waste, the cooling capacity generated by the operation of the cooling system is usually stored in the coolant in the containment box. When the laser starts to emit light, the coolant in the containment box is used to cool some of the heating components.

[0004] However, when the laser does not emit light for a long time, the cooling capacity generated by the operation of the cooling system will cause the temperature of the coolant in the containment box to be too low. When some heat-generating components are cooled by the coolant in the containment box, the temperature of some heat-generating components will be too low, resulting in condensed water.

In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application.

In addition, the present application provides various specific processes and examples of materials, but those of ordinary skill in the art can appreciate the application of other processes and / or the use of other materials.

[0037] The embodiments of the present application provide a refrigeration system and a laser, which are described in detail below.

[0038] First, an embodiment of the present application provides a refrigeration system.

[0039] Figure 1 This is a schematic diagram of the structure of an embodiment of the refrigeration system provided in the present application. Figure 1As shown, the refrigeration system 100 includes a cabinet 110, a cooling component 130 and a refrigerant supply component 140. The cabinet 110 includes an installation cavity 111. The cooling component 130 includes a first cooling member 131 arranged in the installation cavity 111. The first cooling member 131 is used to install the heating device 200. A refrigerant channel 1311 is provided in the first cooling member 131. The refrigerant supply component 140 is connected to the refrigerant channel 1311 of the first cooling member 131 and is used to supply refrigerant to the refrigerant channel 1311 of the first cooling member 131, so as to cool the first cooling member 131 through the refrigerant, thereby enabling the first cooling member 131 to cool the heating device 200.

[0040] When the refrigeration system 100 is used for a laser, the heating device 200 installed on the first cooling member 131 can be a pump source for emitting pump light. Of course, the refrigeration system 100 can be used in other equipment that requires cooling of the heating device 200.

[0041] In some embodiments, the refrigerant supply assembly 140 includes a connecting pipe 141, and a compressor 142, a condenser 143, and an expansion valve 144 that are connected in sequence, that is, the output end of the compressor 142 is connected to the input end of the condenser 143, and the output end of the condenser 143 is connected to the input end of the expansion valve 144. The output end of the expansion valve 144 is connected to the input end of the refrigerant channel 1311 of the first cooling member 131, and the output end of the refrigerant channel 1311 of the first cooling member 131 is connected to the input end of the compressor 142 through the connecting pipe 141. Thus, the compressor 142 can compress the gaseous refrigerant and transmit it to the condenser 143, and cool the refrigerant through the condenser 143. Afterwards, the refrigerant in the condenser 143 is transmitted to the refrigerant channel 1311 of the first cooling component 131 via the expansion valve 144 to cool the first cooling component 131; finally, the refrigerant in the refrigerant channel 1311 of the first cooling component 131 is transmitted to the compressor 142 through the connecting pipe 141 to realize the recycling of the refrigerant.

[0042] The cabinet 110 may include a receiving cavity 112 isolated from the installation cavity 111, and the condenser 143 may be installed in the receiving cavity 112 to prevent the high-temperature gas generated by the condenser 143 from entering the installation cavity 111. In addition, the refrigerant supply component 140 also includes a cooling fan 120, which is used to cool the condenser 143. Specifically, the cooling fan 120 is used to blow air to the condenser 143 to dissipate heat from the condenser 143, or the cooling fan 120 is used to extract the gas in the receiving cavity 112, so that the air outside the cabinet 110 enters the receiving cavity 112 and flows through the condenser 143 to dissipate heat from the condenser 143.

[0043] Continue to refer to Figure 1The cooling assembly 130 further includes a second cooling member 132 disposed in the mounting cavity 111 of the cabinet 110, and the second cooling member 132 is used to mount other heat generating devices 200 to cool the other heat generating devices 200. A liquid cooling channel (not shown in the figure) is disposed in the second cooling member 132, and the refrigeration system 100 includes a cooling liquid supply assembly 160, which is in communication with the liquid cooling channel of the second cooling member 132 and is used to supply cooling liquid to the liquid cooling channel of the second cooling member 132, so as to cool the second cooling member 132 through the cooling liquid, thereby enabling the second cooling member 132 to cool the other heat generating devices 200.

[0044] The cooling liquid supply assembly 160 includes a receiving box 161 and a water pump 163. The receiving box 161 is disposed in the installation cavity 111 of the cabinet 110. The input end of the water pump 163 is communicated with the receiving box 161, the output end of the water pump 163 is communicated with the input end of the liquid cooling channel, and the output end of the liquid cooling channel is communicated with the receiving box 161. Thus, the water pump 163 can pump the cooling liquid in the receiving box 161 into the liquid cooling channel of the second cooling member 132, and the cooling liquid can flow back to the receiving box 161 from the output end of the liquid cooling channel of the second cooling member 132, so as to realize the circulation of the cooling liquid.

[0045] In some embodiments, at least part of the connecting pipe 141 of the refrigerant supply assembly 140 can be located in the receiving box 161. Thus, the refrigerant flowing through the connecting pipe 141 can cool the coolant in the receiving box 161 to reduce the temperature of the coolant, thereby improving the cooling effect of the coolant on the second cooling member 132.

[0046] Since the heating device 200 installed on the first cooling member 131 will frequently switch between the running state and the stopping state, in order to avoid the cooling system being unable to cool the heating device 200 in time when the heating device 200 switches from the stopping state to the running state, after the heating device 200 switches from the running state to the stopping state, the cooling system needs to maintain normal operation to continuously cool the first cooling member 131.

[0047] However, when the heating device 200 installed on the first cooling member 131 is in a stopped state for a long time, the long-term operation of the refrigeration system 100 will cause the refrigerant to continuously cool the coolant in the containing box 161 when flowing through the connecting pipe 141, resulting in the temperature of the coolant and the containing box 161 being too low. When the water pump 163 transfers the coolant to the liquid cooling channel of the second cooling member 132, the temperature of the second cooling member 132 will be quickly reduced, resulting in the surface of the second cooling member 132 and other heating devices installed on the second cooling member 132 being too low in temperature and generating condensed water, thereby affecting the performance of other heating devices installed on the second cooling member 132.

[0048] In order to avoid the above problems, Figure 1 As shown, the refrigerant supply assembly 140 of the refrigeration system 100 provided in the embodiment of the present application further includes a bypass line 145, and the output end of the compressor 142 is also connected to the input end of the connecting line 141 through the bypass line 145, and a first control valve 1451 is provided on the bypass line 145. When the first control valve 1451 is opened, the refrigerant in the compressor 142 can be directly transmitted to the connecting line 141 through the bypass line 145, and when the first control valve 1451 is closed, the refrigerant in the compressor 142 passes through the condenser 143, the expansion valve 144 and the refrigerant channel 1311 of the first cooling member 131 in sequence and then enters the connecting line 141.

[0049] In addition, the refrigeration system 100 provided in the embodiment of the present application also includes a control component (not shown in the figure) electrically connected to the first control valve 1451 of the bypass line 145, and the control component is used to detect the dew point temperature in the installation cavity 111 and the temperature of the coolant in the containing box 161 when the heating device 200 stops running, and control the first control valve 1451 to open when the temperature difference between the coolant temperature and the dew point temperature of the installation cavity 111 is less than or equal to the first preset temperature difference.

[0050] The refrigeration system 100 provided in the embodiment of the present application enables the control component to detect the dew point temperature in the installation cavity 111 and the temperature of the coolant in the containing box 161 when the heating device 200 stops running, and controls the first control valve 1451 to open when the temperature difference between the coolant temperature and the dew point temperature of the installation cavity 111 is less than or equal to the first preset temperature difference. This can enable the compressor 142 to maintain normal operation while at least part of the high-temperature and high-pressure refrigerant output from the compressor 142 is transmitted to the connecting pipe 141 through the bypass line 145 to heat the coolant in the containing box 161 and increase the temperature of the coolant in the containing box 161, thereby avoiding the problem that the temperature of the coolant in the containing box 161 is too low, which causes the surface of the second cooling member 132 and other heating devices installed on the second cooling member 132 to be too low after the water pump 163 transmits the coolant to the liquid cooling channel of the second cooling member 132, resulting in condensed water.

[0051] The first preset temperature difference may be a temperature difference determined by experiment. For example, the refrigeration system may be experimented, and when the temperature difference between the dew point temperature in the installation cavity 111 of the cabinet 110 and the temperature of the coolant in the container 161 is less than or equal to a certain temperature difference, the water pump 163 transfers the coolant to the liquid cooling channel of the second cooling element 132, and then condensed water is generated on the surface of the second cooling element 132, and on the surface of other heating devices installed on the second cooling element 132, then the certain temperature difference may be used as the first preset temperature difference. Of course, the specific value of the first preset temperature difference may also be determined based on experience.

[0052] In addition, the dew point temperature in the installation cavity 111 refers to the condensation temperature in the installation cavity 111. When the temperature in the installation cavity 111 is less than or equal to the dew point temperature, condensation will form in the installation cavity 111. The dew point temperature in the installation cavity 111 is determined according to the temperature and humidity in the installation cavity 111. If the temperature and humidity in the installation cavity 111 are different, the dew point temperature in the installation cavity 111 will also be different.

[0053] It should be noted that when the coolant temperature is less than or equal to the dew point temperature, the control component can also control the first control valve 1451 to open, so as to avoid the problem of condensed water being generated due to the surface of the second cooling member 132 and other heating devices installed on the second cooling member 132 being too low in temperature after the water pump 163 transfers the coolant with too low a temperature to the liquid cooling channel of the second cooling member 132.

[0054] In some embodiments, the first preset temperature difference can be less than or equal to 2°C. The first preset temperature difference can be 0°C, 0.5°C, 1°C, 1.5°C, etc., or the first preset temperature difference can be greater than 2°C, as long as it can avoid that when the second cooling member 132 is cooled by the coolant, the surface of the second cooling member 132 and the surfaces of other heating devices installed on the second cooling member 132 will not generate condensed water, and there is no limitation here.

[0055] In some embodiments, the compressor 142 can be a variable frequency compressor, the control component is electrically connected to the compressor 142, and the control component is also used to control the frequency of the compressor 142 to be reduced to a preset frequency after the heating device 200 stops running for a first preset time. In this way, it is possible to avoid energy waste caused by the compressor 142 continuing to maintain normal operation after the heating device 200 stops running for a long time. Among them, the first preset time can be 3 minutes, 5 minutes, etc. In addition, the frequency of the compressor 142 can be reduced to 50%, 30%, etc., which is not limited here.

[0056] like Figure 1 As shown, the refrigerant supply component 140 also includes a cooling fan 120, which is used to cool the condenser 143. In some embodiments, the control component can be electrically connected to the cooling fan 120, and the control component is also used to control the cooling fan 120 to reduce to a preset speed after the heating device 200 stops running for a second preset time. In this way, it is possible to avoid energy waste caused by the compressor 142 continuing to maintain normal operation after the heating device 200 stops running for a long time. Among them, the second preset time can be 3 minutes, 5 minutes, etc. In addition, the speed of the cooling fan 120 can be reduced to 50%, 30%, 0%, etc., which is not limited here.

[0057] In some embodiments, the control component can also be electrically connected to the expansion valve 144, and the control component is also used to control the opening of the expansion valve 144 to decrease to a preset opening after the heating device 200 stops running for a third preset time to avoid energy waste. The third preset time can be 3 minutes, 5 minutes, etc. In addition, the opening of the expansion valve 144 can be reduced to 50%, 30%, 0%, etc., which is not limited here.

[0058] It should be noted that, when the heating device 200 stops running for a long time, the control component can reduce the speed of the compressor 142, the speed of the cooling fan 120, and the opening of the expansion valve 144 at the same time, or only reduce one or both of the speed of the compressor 142, the speed of the cooling fan 120, and the opening of the expansion valve 144. Of course, the former can make the adjustment of the refrigeration system 100 more flexible.

[0059] In addition, the first preset time length, the second preset time length and the third preset time length may be the same time length or different time lengths, which may be determined according to the structure of the compressor 142, the cooling fan 120 and the expansion valve 144, and is not limited here.

[0060] In some embodiments, the control component may include a controller, and a temperature and humidity sensor (not shown in the figure) and a temperature sensor (not shown in the figure) electrically connected to the controller. The temperature and humidity sensor is disposed in the installation cavity 111, and is used to detect the temperature and humidity in the installation cavity 111, and output a corresponding temperature and humidity signal to the controller. The temperature sensor is disposed in the receiving box 161, and is used to detect the temperature of the coolant in the receiving box 161, and output a corresponding temperature signal to the controller. The controller determines the dew point temperature in the installation cavity 111 according to the temperature and humidity signal, and determines the temperature of the coolant in the receiving box 161 according to the temperature signal, and then determines the size and difference of the dew point temperature and the coolant temperature according to the dew point temperature in the installation cavity 111 and the temperature of the coolant in the receiving cavity 161.

[0061] The controller is electrically connected to the first control valve 1451, and is used to control the first control valve 1451 to open when the heating device 200 stops running and the temperature difference is less than or equal to the first preset temperature difference. In addition, the controller is electrically connected to the compressor 142, the cooling fan 120 and the expansion valve 144 to reduce the speed of the compressor 142, the speed of the cooling fan 120, and the opening of the expansion valve 144.

[0062] In some embodiments, Figure 1As shown, a second control valve 1452 may be provided on the pipeline between the output end of the compressor 142 and the input end of the condenser 143, and the second control valve 1452 is electrically connected to the control component, and the control component is used to control the second control valve 1452 to close when the heating device 200 stops running. Thus, when the heating device 200 stops running and the controller controls the first control valve 1451 to open, the compressor 142 can transmit all the refrigerant to the connecting pipeline 141, so as to further improve the heating efficiency of the coolant in the containing box 161.

[0063] In addition, a third control valve 1453 may be provided between the output end of the refrigerant channel 1311 and the input end of the connecting pipeline 141, and the third control valve 1453 is electrically connected to the control component, and the control component is used to control the third control valve 1453 to close when the heating device 200 stops running. Thus, when the heating device 200 stops running and the controller controls the first control valve 1451 to open, it is possible to prevent the high-temperature and high-pressure refrigerant flowing out of the output end of the compressor 142 from flowing back into the refrigerant channel 1311 from the output end of the refrigerant channel 1311 of the first cooling member 131.

[0064] It should be noted that the refrigeration system 100 may include both the second control valve 1452 and the third control valve 1453, or only one of the second control valve 1452 and the third control valve 1453, or even neither of the second control valve 1452 and the third control valve 1453. Of course, the former can further improve the heating efficiency of the coolant in the containing box 161 when the heating device 200 stops running and the controller controls the first control valve 1451 to open.

[0065] In some embodiments, Figure 1 As shown, the cooling liquid supply component 160 may include a heating component 162 disposed in the receiving box 161, and the heating component 162 is electrically connected to the control component, and the control component is used to control the heating component 162 to heat the cooling liquid in the receiving box 161 when the heating device 200 stops running and the cooling liquid temperature is less than or equal to the dew point temperature, or when the cooling liquid temperature is greater than the dew point temperature, and the temperature difference between the cooling liquid temperature and the dew point temperature is less than or equal to the second preset temperature difference. Therefore, when the temperature difference between the dew point temperature of the installation cavity 111 of the cabinet 110 and the temperature of the cooling liquid in the receiving box 161 is too small, or even when the cooling liquid temperature in the receiving box 161 is less than the dew point temperature of the installation cavity 111, the cooling liquid in the receiving box 161 can be heated by the heating component 162 to quickly increase the temperature of the cooling liquid in the receiving box 161.

[0066] It should be noted that the second preset temperature difference may be the same as or different from the first preset temperature difference, and this is not limited here.

[0067] In some embodiments, Figure 2 As shown, the refrigerant channel 1311 includes an inlet section 1312, a cavity 1314 and an outlet section 1316 which are sequentially connected from the input end to the output end thereof, wherein the end of the inlet section 1312 away from the cavity 1314 is connected to the output end of the expansion valve 144, and the end of the outlet section 1316 away from the cavity 1314 is connected to the input end of the connecting pipeline 141. Thus, a certain amount of liquid refrigerant can be contained in the cavity 1314 of the first cooling member 131, and when the heating device 200 is switched from the stop state to the running state, the liquid refrigerant in the first cooling member 131 can be gasified to quickly absorb the heat of the first cooling member 131, so that the first cooling member 131 is quickly cooled, and then the first cooling member 131 can quickly cool the heating device 200.

[0068] Continue to refer to Figure 2 , the first cooling member 131 includes a mounting surface 1318, and the heating device 200 is mounted on the mounting surface 1318. The cavity 1314 includes a bottom surface 1315, and the bottom surface 1315 is located on a side of the cavity 1314 close to the mounting surface 1318. In some embodiments, the outlet section 1316 of the first cooling member 131 includes a first opening 1317 connected to the cavity 1314, and the minimum distance between the first opening 1317 and the mounting surface 1318 is greater than the minimum distance between the bottom surface 1315 and the mounting surface 1318. As a result, more liquid refrigerant can remain in the cavity 1314, so as to further improve the cooling effect of the first cooling member 131 on the heating device 200.

[0069] In some embodiments, the difference between the minimum distance from the first opening 1317 of the outlet section 1316 to the mounting surface 1318 of the first cooling member 131 and the minimum distance from the bottom surface 1315 of the cavity 1314 to the mounting surface 1318 of the first cooling member 131 can be greater than or equal to 2 mm, so that more liquid refrigerant can remain in the cavity 1314.

[0070] In addition, the difference between the minimum distance from the first opening 1317 of the outlet section 1316 to the mounting surface 1318 of the first cooling member 131 and the minimum distance from the bottom surface 1315 of the cavity 1314 to the mounting surface 1318 of the first cooling member 131 can be made less than or equal to 5 mm, so as to avoid that the difference between the minimum distance from the first opening 1317 of the outlet section 1316 to the mounting surface 1318 of the first cooling member 131 and the minimum distance from the bottom surface 1315 of the cavity 1314 to the mounting surface 1318 of the first cooling member 131 is too large, which results in a larger size of the first cooling member 131.

[0071] Among them, the difference between the minimum distance from the first opening 1317 of the outlet section 1316 to the mounting surface 1318 of the first cooling member 131 and the minimum distance from the bottom surface 1315 of the cavity 1314 to the mounting surface 1318 of the first cooling member 131 can be 2.5mm, 3mm, 3.2mm, 4mm, etc., and there is no limitation here.

[0072] Similarly, the inlet section 1312 of the first cooling member 131 may include a second opening 1313 connected to the cavity 1314 , and the minimum distance between the second opening 1313 and the mounting surface 1318 may be greater than the minimum distance between the bottom surface 1315 and the mounting surface 1318 , so that more liquid refrigerant remains in the cavity 1314 .

[0073] The difference between the minimum distance between the second opening 1313 of the inlet section 1312 and the mounting surface 1318 of the first cooling member 131 and the minimum distance between the bottom surface 1315 of the cavity 1314 and the mounting surface 1318 of the first cooling member 131 can be greater than or equal to 2 mm, so that more liquid refrigerant can remain in the cavity 1314. In addition, the minimum distance between the second opening 1313 of the inlet section 1312 and the mounting surface 1318 of the first cooling member 131 and the minimum distance between the bottom surface 1315 of the cavity 1314 and the mounting surface 1318 of the first cooling member 131 can be less than or equal to 5 mm, so as to avoid the first cooling member 131 being too large.

[0074] The difference between the minimum distance from the second opening 1313 of the inlet section 1312 to the mounting surface 1318 of the first cooling member 131 and the minimum distance from the bottom surface 1315 of the cavity 1314 to the mounting surface 1318 of the first cooling member 131 can be 2.5 mm, 3 mm, 3.2 mm, 4 mm, etc., and is not limited here.
