[0025] Example 1

[0026] This invention provides a multi-channel test bench, such as Figure 1-6 As shown, the test platform includes a test bench 1. A panel 2 is fixedly connected to the upper front end of the test bench 1. Several mounting brackets 3 are fixedly connected to the rear end of the panel 2. External ball valves 4 are fixedly connected to the upper and lower front ends of the mounting brackets 3. An inlet 5 and an outlet 6 are fixedly connected to the middle part of the mounting brackets 3, respectively. U-shaped pipes 7 are connected between the external ball valves 4 and the inlet 5, and between the external ball valves 4 and the outlet 6, to facilitate external control of the opening and closing of the test. A connecting pipe 8 is connected to the rear end of the lower external ball valve 4. A three-way connector 9 is connected to the rear end of the upper external ball valve 4 and the other end of the connecting pipe 8. A thermometer 10 is connected to the outer surface of the three-way connector 9, which can detect and record the temperature and pressure of the incoming and outgoing liquids. A three-way sensing valve 11 is connected to the third end of the three-way connector 9. A flow valve 12 is connected to the bottom end of the lower three-way sensing valve 11, which can control the flow rate. A filter 13 is connected to the bottom end of the flow valve 12. It can filter the liquid fed into the water-cooled server. The top of the upper three-way sensing valve 11 and the bottom of the filter 13 are both fixedly connected to stainless steel ball valves 14. The lower stainless steel ball valve 14 is connected to the water inlet pipe 15, and the upper stainless steel ball valve 14 is connected to the water outlet pipe 16. The third end of the three-way sensing valve 11 is connected to the signal sensing valve 17, and the other end of the signal sensing valve 17 is connected to the connecting air pipe 18. The signal sensing valve 17 can control whether the connecting air pipe 18 and the three-way sensing valve 11 are connected. The upper three-way sensing valve 11 can control whether the three-way connector 9, the signal sensing valve 17 and the stainless steel ball valve 14 are connected. The lower three-way sensing valve 11 can control whether the three-way connector 9, the signal sensing valve 17 and the flow valve 12 are connected. The other end of the lower connecting air pipe 18 is connected to the air inlet pipe 19, and the other end of the upper connecting air pipe 18 is connected to the air outlet pipe 20, which facilitates the control and stability of the overall water inlet and outlet.

[0027] like Figure 1-6As shown, a pressure gauge 21 is fixedly connected to the center of panel 2, and a display screen 22 is also fixedly connected to the center of panel 2. The display screen 22 is connected to all the electrically controlled valves on the equipment, eliminating the need for manual valve adjustment; different modes can be selected simply by selecting them on the screen. A vent pipe 23 is connected to the upper middle part of the air inlet pipe 19, and the other end of the vent pipe 23 is connected to the rear end of the pressure gauge 21. This allows for pressure testing of the high-pressure gas entering the cooling server, facilitating personnel observation and ensuring that pressure discrepancies do not occur. A connecting housing 24 is fixedly connected to the left side of the test bench 1. A fixing frame 25 is fixedly connected to the inner side of the 24. A heat exchanger 26 is fixedly connected to the upper inner side of the fixing frame 25.

An electric three-way valve 30 is fixedly connected to the outer surface of the cooling tower water supply inlet 29. By connecting with an external cooling tower, the heat exchanger 26 can cool the hot water that has completed the heat exchange with the cooling server.

[0028] like Figure 1-6 As shown, an insulated box 31 is fixedly connected to the left end of the connecting box 24. A temperature transmitter 32 and a level transmitter 33 are connected sequentially from left to right on the upper front side of the insulated box 31. The temperature transmitter 32 is a device that can convert physical measurement signals or ordinary electrical signals into standard electrical signals for output or output via a communication protocol, used for measuring and controlling the temperature parameters inside the insulated box 31. The level transmitter 33 can accurately measure and control the volume, liquid level, and weight of the water inside the insulated box 31. A water tank level gauge 34 is fixedly connected to the front end of the insulated box 31, displaying the liquid level height inside the insulated box 31 for easy observation by staff. A water tank level gauge 34 is fixedly connected to the middle of the top of the insulated box 31. The insulation box 31 has a top cover 35 and a water inlet 36 on the front left side of the top, which facilitates water replenishment to the insulation box 31. The left end of the air inlet pipe 19 is connected to a connecting pipe 37, and the other end of the connecting pipe 37 is connected to an air guide pipe 38. Several pressure reducing valves 39 are fixedly connected to the upper end of the air guide pipe 38. Each pressure reducing valve 39 represents a different air pressure, which is convenient for different tests on the cooling server. The other end of the pressure reducing valve 39 is fixedly connected to an air inlet 40, which is connected to an external air compressor. The bottom upper end of the connecting box 24 is fixedly connected to a circulation pump 41. The rear end of the circulation pump 41 is connected to the left end of the water inlet pipe 15, and the other end of the circulation pump 41 is connected to the inner surface of the insulation box 31, which is convenient for stable testing of the cooling server.

[0029] like Figure 1-6As shown, a chilled pump 42 is fixedly connected to the upper bottom of the connecting box 24. The left end of the chilled pump 42 is connected to the inner side of the insulation box 31. The upper end of the chilled pump 42 passes through the top of the connecting box 24 and is connected to a chiller water supply port 43, which can reduce the internal temperature inside the insulation box 31. A control box 44 is set at the upper bottom of the test bench 1 for installing the necessary electrical control components. Casters 45 are fixedly connected to the bottom of the test bench 1, the connecting box 24, and the insulation box 31 for easy transportation and movement. An electric heating rod 46 is fixedly connected to the right inner side of the insulation box 31 to heat the liquid inside the insulation box 31. Several reinforcing ribs 47 and triangular plates 48 are fixedly connected to the inner side of the insulation box 31 to improve the service life and safety of the insulation box 31. A chiller return water inlet 49 is set at the middle of the right side of the top of the insulation box 31. The output end pipes of the chiller supply water inlet 43 and the chiller return water inlet 49 are connected to an external air-cooled chiller. The output end pipes of the cooling tower return water inlet 28 and the cooling tower supply water inlet 29 are connected to an external cooling tower. The output end pipes of the input port 5 and the output port 6 are connected to a water-cooled server. With the combined action of the air-cooled chiller, the chilled pump 42 and the electric heating rod 46, the temperature inside the insulation box 31 can be constantly regulated, improving the stability and reliability of the test.

[0030] Working principle: During use, starting the heating rod 46 heats the liquid inside the insulation box 31, while starting the chiller pump 42 exchanges the liquid inside the insulation box 31 with the external air-cooled chiller, thus cooling the insulation box 31. The temperature transmitter 32 connects to control the heating rod 46 and the chiller pump 42, allowing for uniform temperature control within the insulation box 31. Connecting the input and output terminals of the cooling server to output port 6 and input port 5 respectively, and starting the circulation pump 41, the liquid inside the insulation box 31 flows from the inlet pipe 15 into the filter. Filter 13 and flow valve 12 control the inlet and outlet flow rates. Filter 13 filters the liquid fed into the water-cooled server. The display screen 22 controls the three-way induction valve 11 and the stainless steel ball valve 14 to close the three-way induction valve 11 to the signal induction valve 17. This allows the liquid to sequentially enter the cooling server through the stainless steel ball valve 14, the three-way induction valve 11, the three-way connector 9, the U-tube 7, the external ball valve 4, and the outlet 6. It then flows back from the inlet 5 to the outlet pipe 16 and enters the heat exchanger 26 for heat exchange. Finally, the liquid returns through the cooling tower. The inlet 28 and cooling tower water supply inlet 29 are connected to the external cooling tower. By controlling the opening and closing of the electric three-way valve 30, the heat exchanger 26 can be controlled to open and close. After heat exchange is completed in the heat exchanger 26, the gas enters the insulation box 31 through the transfer pipe 27 to complete the test and circulation. The external air compressor is started to supply air to the air inlet 40. By adjusting the pressure through the pressure reducing valve 39, the functionality of the test is changed. High-pressure gas enters the air inlet pipe 19 from the air guide pipe 38 and connecting pipe 37. By adjusting the signal sensing valve 17 and the three-way sensing valve 11, the upper side is controlled. The closure of the stainless steel ball valve 14 and the flow valve 12 allows gas to enter the cooling server from the outlet 6, return through the U-tube 7, and then sequentially enter the outlet pipe 20 through the external ball valve 4, the three-way connector 9, the three-way sensing valve 11, the signal sensing valve 17, and the connecting air pipe 18, and exit from the left side of the outlet pipe 20. This process also removes residual liquid from the cooling server. During this process, data can be collected and recorded using the thermometer 10, pressure gauge 21, three-way sensing valve 11, and signal sensing valve 17, thus completing the cooling and pressure testing of the cooling server.
