[0028] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0029] The first implementation method:

The water outlet of the liquid collecting tank 20 is connected to the water stop valve E26 through a pipeline. The water inlet of the liquid collecting tank 20 is connected to the water stop valve B23 through a pipeline. The input end of the water stop valve B23 is connected to a T-tube 1. The other two input ends of the T-tube 1 are respectively connected to a filter tube A55 and a filter tube B56 arranged in parallel. The filter tubes A55 and B56 are both provided with a flow detector 53. The filter tube A55 is connected to the water stop valve D51 through a pipeline. The filter tube B56 is connected to the water stop valve C50 through a pipeline. The water inlets of the water stop valve C50 and the water stop valve D51 are connected to a T-tube 2. The water inlet of the T-tube 2 is connected to a vertical pipeline 54. The vertical pipeline 54 is provided with multiple A cold water pan interface B52 connected to the water outlet of the cold water coil 10; the output end of the water stop valve E26 is connected to a three-way pipe, the other input end of the three-way pipe is a heat dissipation device interface 43, the output end of the three-way pipe is connected to a water pump 40, the exhaust valve 41 is a device that automatically discharges the gas in the liquid pipeline through a mechanical structure, the output end of the water pump 40 is connected to the exhaust valve 41, and the pipeline under the exhaust valve 41 is provided with multiple cold water pan interfaces A42, each cold water pan interface A42 is connected to the water inlet of the corresponding cold water coil 10, through the above structure, when the water coolant is replaced, the water stop valve E26 and the water stop valve B23 will automatically open, one of the water stop valve C50 and the water stop valve D51 will be opened, and the water pump 40 Normal operation, at this time, the new water-cooling liquid in the liquid collecting tank 20 will flow from the cold water disk interface A42 into the cold water coil 10 and other connecting pipes under the action of the water pump 40. In this process, the old water-cooling liquid in the cold water coil 10 and other connecting pipes will be pushed to the liquid collecting tank 20 after passing through the filter net by the new water-cooling liquid. After the old water-cooling liquid in the cold water coil 10 and other connecting pipes are replaced, the water stop valve E26 and the water stop valve B23 will be automatically closed. At this time, the old water-cooling liquid that has been replaced is stored in the liquid collecting tank 20. The heat dissipation device 3 includes multiple cooling fans 30, multiple cooling pipes 32 arranged on the air ducts of the multiple cooling fans 30, and the water inlets of the multiple cooling pipes 32 are commonly connected to the water stop valve A33.

[0031] In addition, the intelligent signal processor includes a temperature control module and a water-cooling liquid replacement module. The temperature control module is electrically connected to the water pump 40. The temperature control module can control the operation and stop of the water pump 40, and the temperature control module can also control the operating power of the water pump 40. The water-cooling liquid replacement module is electrically connected to the water stop valve A33, the water stop valve C50, the water stop valve D51, the water stop valve E26, the flow detector 53 and the water stop valve B23. The water-cooling liquid replacement module can control the opening and closing of the water stop valve A33, the water stop valve B23, the water stop valve C50, the water stop valve D51 and the water stop valve E26. The flow detector 53 is used by the water-cooling liquid replacement module to monitor the filter tube A55 and the filter tube B56. The temperature control modules are electrically connected to the plurality of cooling fans 30. The temperature control modules can control the start and stop of the cooling fans 30, as well as the operating power of the cooling fans 30. The temperature control modules are all connected to the control panel 6 and the cooling liquid replacement module signal. The temperature control module will send the operating power of the water pump 40 to the cooling liquid replacement module to avoid the flow detector 53 from affecting the monitoring of the liquid flow rate due to the change of the water pump 40 power. When the switch body 11 in the loading cabinet 1 is operating normally, a large amount of heat is generated. At this time, the technician can start the temperature control module through the control panel 6. The temperature control module will control the power of the water pump 40 and the cooling fan 30. The machine is powered on to put the water-cooling liquid device into use. At the same time, the water-cooling liquid replacement module has controlled the water stop valve A33 and the filter tube A55 to open, and the water stop valve B23, the water stop valve E26 and the filter tube B56 to close. If the temperature continues to rise after a period of time, the temperature control module can also be controlled through the control panel 6 to increase the operating power of the water pump 40 and the cooling fan 30, thereby accelerating the diffusion of heat in the loading cabinet 1; during the above operation process, the water-cooling liquid replacement module will monitor the liquid flow rate through the corresponding flow detector 53. When the flow rate is detected to be lower than the set value (the normal liquid flow rate value is preset in the water-cooling liquid replacement module), the water-cooling liquid replacement module will control the water stop valve A33 to close, the water stop valve E26 and the filter tube B56 to close. Valve B23 and water stop valve E26 are opened, and the new water coolant in the liquid collection tank 20 will be replaced into the water cooling device. When the set time is reached, the water coolant replacement module will control the filter tube B56 and the water stop valve A33 to open, and the filter tube A55, the water stop valve B23 and the water stop valve E26 to close. After the above are completed, the filtered particles in the filter tube A55 can be cleaned by disassembling the filter tube A55, and the water coolant retained in the liquid collection tank 20 can be discharged from the discharge port 25, and then new water coolant is added from the addition port 24. Although gas may enter the water cooling system to affect the water cooling efficiency during the replacement process, the gas entering will be automatically discharged from the exhaust valve 41.

[0032] In addition, the heat dissipation device 3 also includes a heat dissipation plate 31 fixed on a plurality of heat dissipation tubes 32, and a plurality of heat dissipation fans 30 are installed on the outer side of the heat dissipation plate 31. Through the above arrangement, the water-cooling liquid can be quickly cooled down. The water stop valve A33 is arranged between the T-tube and the water stop valve B23. Adjacent switch bodies 11 are symmetrically stacked in the switch cabinet 12. The cold water coil 10 is arranged on the side of the heat source close to the switch body 11. The heat source is usually generated by heat-generating components such as chips. The heat on the chip side is much higher than the heat on the side without chips. The design of such a structure can not only realize high-efficiency heat exchange of the cold water coil 10, but also greatly improve the utilization rate of the space.

[0033] In addition, filter screens are provided in filter tube A55 and filter tube B56, and the filter screens are provided at the lower ends of filter tube A55 and filter tube B56. The purpose of this arrangement is to store the filtered solid particles in filter tube A55 and filter tube B56 under the action of gravity and water flow. Since filter tube A55 and filter tube B56 are provided with a simple installation and removal method, when one of filter tube A55 and filter tube B56 is used, the other one can be removed to facilitate cleaning of the filter screen. Through the above method, the filter screen can be cleaned without stopping the operation of the water cooling device, thereby improving the operation efficiency of the device.

[0034] In addition, a temperature sensor is fixed in the switch cabinet 12, and the temperature sensor is electrically connected to the temperature control module. The temperature sensor is a sensor used by the temperature control module to monitor the temperature in the loading cabinet 1. The temperature sensor set in the switch cabinet 12 can inform the temperature control module of the monitored value. When the temperature control module detects that the temperature in the loading cabinet 1 exceeds the set value (the temperature setting value is the temperature most suitable for the operation of the switch body 11, and its value is set in the temperature control module), the temperature control module will automatically control the water pump 40 and the cooling fan 30 motor to be energized. If the temperature continues to rise after a period of time, the temperature control module will automatically control the water pump 40 and the cooling fan 30 to increase the operating power, thereby accelerating the diffusion of heat in the loading cabinet 1. In the above manner, the temperature control module can be fully automatically controlled to achieve the effect of liberating manpower.

[0035] In addition, multiple cold water coils 10 are connected in parallel to the cold water pan interface A42 and the cold water pan interface B52. Compared with the series connection, the above parallel setting can improve the cooling efficiency of each cycle of the water-cooled liquid; an air circulation channel is reserved between the liquid storage device 2 and the heat dissipation device 3. This setting is to allow the heat dissipation device 3 to have a better air duct, which is conducive to the heat dissipation device 3 to release the heat in the water-cooled liquid to the external environment.

[0036] The second implementation method:

[0037] See also Figure 4and Fig. 9 Different from the first embodiment, the liquid storage device 2 includes a liquid collecting tank 20 and a water-cooling liquid detector 21 and a regulator additive 22 arranged on the top of the liquid collecting tank 20. The intelligent signal processor also includes a water-cooling liquid recycling module, which is electrically connected to the water-cooling liquid detector 21 and the regulator additive 22 respectively. The water-cooling liquid detector 21 is a detector for detecting the specific heat capacity of the water-cooling liquid. The water-cooling liquid recycling module can detect whether the water-cooling liquid in the liquid collecting tank 20 is suitable for use through the water-cooling liquid detector 21, and can adjust the water-cooling liquid in the liquid collecting tank 20 that is not suitable for use through the regulator additive 22 so that it can be put into use again, thereby saving water cooling costs.

[0038] To sum up, the second implementation mode can utilize the water-cooling liquid recycling module to process the water-cooling liquid so that it can be put into use again. When the water-cooling liquid is replaced by the replacement module, the water-cooling liquid recycling module will immediately control the water-cooling liquid detector 21 to detect the replaced water-cooling liquid. Through the detection data, the water-cooling liquid recycling module will automatically control the regulator adder 22 to add a certain amount of regulator. After the regulator is completely diffused, the water-cooling liquid recycling module will control the water-cooling liquid detector 21 to detect the water-cooling liquid again. If qualified, it will wait for the next use of the water-cooling liquid. If unqualified, the water-cooling liquid recycling module will continue to repeat the above operations.

[0039] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
