[0036] In one embodiment, if Figure 2 As shown, a liquid inlet 410 and a liquid outlet 420 are provided on the fixing plate 400 ; an air inlet 111 and an air outlet 112 are provided on the outer wall 110 of the third box body corresponding to the third space, and the air inlet 111 is opposite to the air outlet 112 .

[0037] In this embodiment, the fixing plate 400 is provided with a liquid inlet 410 and a liquid outlet 420, allowing coolant to flow between the first and second spaces within the enclosure through the inlet 410 and outlet 420. This facilitates heat exchange between the coolant and effectively dissipates heat from the liquid-cooled server under test. An air inlet 111 and an air outlet 112 are provided on the third enclosure outer wall 110, corresponding to the third space. Air inlet 111 and air outlet 112 are directly opposite air outlet 112.

[0039] In this embodiment, the test assembly 200 also includes a liquid level sensor 240, an air inlet temperature sensor 250, an air outlet temperature sensor 260, a liquid inlet temperature sensor 270, and a liquid outlet temperature sensor 280.

The control board 210 is connected to the liquid level sensor 240 to obtain coolant level information and monitor the coolant level. When the coolant level falls below the level, an alarm is issued to prompt the user to add coolant, preventing damage to the liquid-cooled server under test due to insufficient coolant during testing.

[0040] In one embodiment, if Figure 2 As shown, the liquid level sensor 240 is arranged in the first space; the air inlet temperature sensor 250 is arranged on one side of the air inlet 111; the air outlet temperature sensor 260 is arranged on one side of the air outlet 112; the liquid inlet temperature sensor 270 is arranged on one side of the liquid inlet 410; and the liquid outlet temperature sensor 280 is arranged on one side of the liquid outlet 420.

[0041] In this embodiment, a liquid level sensor 240 is located within the first space, where the coolant is also located. The liquid level sensor can monitor the coolant level.

[0042] In one embodiment, if Figure 1 、 Figure 2 as well as Figure 4 As shown, the heat dissipation assembly 300 includes a liquid pump 310, a plurality of liquid inlet pipes 320, a plurality of heat-conducting copper sheets 330 and a fan 340; the liquid pump 310 is arranged in the second space, and the liquid pump 310 is connected to the control board 210; the liquid inlet 410 is connected to the pump inlet of the liquid pump 310 through the plurality of liquid inlet pipes 320; the plurality of heat-conducting copper sheets 330 are arranged vertically through the bottom plate 500, and the two ends of the plurality of heat-conducting copper sheets 330 are respectively located in the second space and the third space; the fan 340 is arranged in the third space, and the fan 340 is connected to the control board 210.

[0043] In this embodiment, the heat dissipation assembly 300 includes a liquid pump 310, a plurality of liquid inlet pipes 320, a plurality of heat-conducting copper sheets 330, and a fan 340. The liquid pump 310 is located in the second space. Specifically, a liquid outlet 420 is provided on the left side of the fixed plate 400 near the housing 100, and a plurality of liquid inlets 410 are provided on the right side of the fixed plate 400. The liquid inlet 410 is connected to the pump inlet via a plurality of liquid inlet pipes 320. The pump outlet is located in the second space. The liquid pump 310 draws the coolant 700 from the first space and delivers it to the second space through the liquid outlet 420. After dissipating heat through the plurality of heat-conducting copper sheets 330, the cooled coolant 700 returns to the first space through the liquid outlet 420. Several thermally conductive copper sheets 330 are arranged vertically through the base plate 500, with their ends located in the second and third spaces, respectively. This allows heat from the second space to be transferred to the third space. Simultaneously, the heat transferred to the third space is dissipated by the fan 340 located in the third space, accelerating air circulation and heat exchange, thereby dissipating heat from the thermally conductive copper sheets 330. Furthermore, the liquid pump 310 is connected to the control board 210, and the fan 340 is also connected to the control board 210. The speeds of the liquid pump 310 and fan 340 can be controlled based on information obtained from the control board, ultimately dissipating heat from the liquid-cooled server under test.

[0044] In one embodiment, if Figure 1 as well as Figure 4 As shown, the plurality of thermally conductive copper sheets 330 are arranged at equal intervals.

[0045] In this embodiment, the plurality of thermally conductive copper sheets 330 are arranged at equal intervals, so that the plurality of thermally conductive copper sheets 330 can be in more sufficient contact with the coolant 700, thereby effectively introducing the heat of the coolant 700 in the second space into the third space for heat exchange.

[0046] The present utility model also provides an auxiliary testing system, which includes an auxiliary testing device for a liquid-cooled server as in any of the aforementioned embodiments, and also includes a liquid-cooled server arranged in the auxiliary testing device for the liquid-cooled server; the liquid-cooled server is connected to the auxiliary testing device for the liquid-cooled server.

[0047] In one embodiment, if Figure 5As shown, the control board 210 mainly includes a power interface and a CPLD (Complex Programmable Logic Device) module. The power module inputs the 12V power supply obtained from the liquid-cooled server, which is stepped down by the DCDC (DC-to-DC Converter) power module to power the CPLD. At the same time, the power supply for the liquid level sensor 240 is also provided by the control board 210. Among them, the CPLD controls the speed of the liquid pump and the fan by obtaining information from the liquid-cooled server BMC (Baseboard Management Controller) and sensor information to cool the liquid-cooled server to be tested, ensuring the normal operation of the auxiliary test device of the liquid-cooled server. The specific control process of the control board 210 is as follows:

[0048] First, the CPLD initiates an I2C interrupt to the BMC. After receiving the CPLD interrupt request, the BMC sends the CPU (CPU, English full name Central Processing Unit, Chinese full name Central Processing Unit) temperature information to the CPLD.

[0049] Second, the CPLD determines whether the received temperature is valid: if the received temperature is 0°C, it means that the server is in S5 state, that is, the server is not turned on, and the CPLD controls the fan and liquid pump to be in a stopped state; if the received temperature is non-zero, the temperature information is stored in the register.

[0050] Third, the CPLD determines whether the CPU temperature is greater than the set value T: when the liquid level sensor detects that the coolant level is less than the set value, the CPLD displays the error message EE through the display module; when the liquid level sensor detects that the coolant level is greater than or equal to the set value, the CPLD controls the pump rotation through a PWM (PWM, English full name Pulse Width Modulation, Chinese full name pulse width modulation) signal, the speed is VI, and obtains the temperature difference between the pump inlet and the pump outlet of the liquid pump.

[0051] Fourth, if the CPU temperature received by the CPLD continues to increase, the liquid pump speed is increased; otherwise, the liquid pump speed is reduced until the CPU temperature is maintained within the set value range.

[0052] Fifth, the CPLD determines the temperatures of the liquid inlet and outlet. If both temperatures reach the preset values, the CPLD controls the fan rotation through the PIM. If the temperature difference between the liquid inlet and outlet reaches the preset value, the fan speed is increased until the temperature difference between the liquid inlet and outlet is controlled within the set range.

[0053] An embodiment of the present invention provides an auxiliary testing device and an auxiliary testing system for a liquid-cooled server, which includes a box 100, a test component 200 and a heat dissipation component 300; a fixing plate 400 and a bottom plate 500 are respectively arranged in the box 100 from top to bottom; the space formed between the fixing plate 400 and the top of the box 100 is a first space; the space formed between the fixing plate 400 and the bottom plate 500 is a second space; the space formed between the bottom plate 500 and the bottom of the box 100 is a third space; the first space is used to place a liquid-cooled server 600 to be tested; the test component 200 and the heat dissipation component 300 are arranged in the second space and the third space of the box 100; the first space and the second space both contain coolant 700; the test component 200 is used to perform testing after being connected to the liquid-cooled server 600 to be tested to obtain test results; the heat dissipation component 300 is used to assist in heat dissipation of the liquid-cooled server 600 to be tested.
