In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0033] In this embodiment, a power supply testing method is provided, which is applied to a testing device, wherein the testing device comprises: a power supply insertion component, a fan module, a first damper, and a second damper, wherein the fan module and the power supply insertion component are located on the same side, the first damper is located on the opposite side of the fan module, the power supply insertion component carries a power supply to be tested, and the second damper is located on the power supply insertion component and is located on the same side as a target fan in the power supply to be tested. Figure 2 is a flow chart of a power supply testing method according to an embodiment of the present application. Figure 2 As shown, the process includes the following steps:

[0034] Step S202, adjusting the first damper and / or the second damper according to the first adjustment method, and repeatedly performing the following first operation until the target fan cannot rotate forward after power-on, and determining the target speed according to the determined multiple first speeds: increasing the speed of the first fan included in the fan module until the target fan in the unpowered state starts to reverse; after the target fan in the unpowered state stably reverses, controlling the target fan to power on; when the target fan in the powered-on state achieves stable forward rotation, determining the first speed when the target fan in the unpowered state stably reverses and controlling the target fan to power off; wherein, the value of the first speed in the latter first operation is greater than the value of the first speed in the previous first operation;

[0035] Step S204, adjusting the first damper and / or the second damper according to a second adjustment method, and adjusting the rotation speed of the first fan, so that the first negative wind pressure of the target fan facing the inner side of the test device reaches a target negative wind pressure;

[0036] Step S206, when it is determined that the target fan having the first negative wind pressure reaching the target negative wind pressure is in stable reversal, determining a second speed during the current stable reversal;

[0037] Step S208: determining a test result of the power supply to be tested based on the second rotational speed and the target rotational speed.

[0038] In the above steps, exemplarily, the method also includes: the difference between the value of the first speed in the latter target operation and the value of the first speed in the previous target operation is a first value, wherein the first value includes but is not limited to: 500 revolutions per minute, 800 revolutions per minute, 1000 revolutions per minute, etc., the first value can be pre-set, and the first value can be adjusted according to the application scenario of the power supply to be tested.

This avoids the problem of the target fan being unable to provide heat dissipation service for the power supply normally due to the target fan being unable to achieve stable forward rotation after power-on under the target negative wind pressure environment. This solves the problem in the related art that the test method uses a single reference factor to determine the test result, resulting in limited test effect and low accuracy of the test result. This improves the accuracy of the test result and the stability of the server power supply operation.

Figure 3 , Figure 4 Taking the structure shown in the figure as an example, the scheme in this application is exemplarily described:

[0042] like Figure 3 As shown, the first test fixture 30 includes: a power supply insertion part 301, a fan module 302, a first damper 303, a second damper 304 and a back pressure machine 305, wherein the back pressure machine 305 is used to determine the first negative wind pressure of the target fan facing the inside of the test device.

[0043] Among them, the power input docking terminal 402 is the output terminal insertion port of the power supply to be tested, and the probe of the negative pressure tester will pass through the negative pressure tester probe hole 403 and be fixed near the power input docking terminal 402; the negative pressure tester is used to monitor the negative pressure size of the air inlet of the target fan; the rear damper adjustment screw 405 is used to adjust the opening and closing size and direction of the rear damper 408 to simulate the wind direction and wind size in the server where the power supply to be tested is located; the side damper adjustment knob 411 is used to adjust the opening and closing size and direction of the side damper 406 to adjust the size of the air duct and the negative wind pressure, thereby simulating the wind direction in the server where the power supply to be tested is located and the anti-reversal ability of the power supply to be tested under different negative wind pressure conditions; the fixing knob 413 of the side damper adjustment knob is used to lock the position of the side damper 406.

[0044] Figure 5 is a schematic diagram of device connection according to the test method of an embodiment of the present application, such as Figure 5 As shown, exemplarily, the electronic load is connected to the power supply to be tested through a load line, the electronic load is connected to the first terminal (for example, the personal computer (PC) shown in the figure) through GPIB (General-Purpose Interface Bus) so that the first terminal can adjust the electronic load carried by the power supply to be tested, the first terminal is connected to the test fixture through USB (Universal Serial Bus) so that the first terminal can control the test fixture, and the PDU is connected to the power supply to be tested and the first terminal respectively, so that the first terminal can control the power on and off of the power supply to be tested through the PDU (Power Distribution Unit). The electronic load is connected to the PC end through a GPIB line, and the test fixture is connected to the PC end through USB. The fan speed of the unpowered power supply is checked using a tachometer, and the input end of the power supply to be tested is connected to the intelligent PDU to control the input power of the power supply.

[0045] In an optional embodiment, after controlling the target fan to power on, the method also includes: determining a first starting current value when the target fan is powered on; when the target fan in the power-on state achieves stable forward rotation, determining the maximum first current value of the target fan in the process from entering the power-on state to achieving stable forward rotation; determining the test result of the power supply to be tested based on the second speed and the target speed includes: determining the test result of the power supply to be tested based on the second speed, the target speed, the first starting current value and the first current value.

[0046] In the above steps, by determining the starting current value of the target fan when it is powered on under stable reverse rotation and the maximum current value of the target fan from power-on to stable forward rotation, it is possible to determine that the current target fan in the power supply to be tested has insufficient capacity when the starting current value and the maximum current value exceed the maximum current that the power supply to be tested can carry during normal operation, thereby avoiding the problem of power supply damage caused by the current of the target fan exceeding the carrying capacity of the power supply to be tested, thereby improving the test effect.

[0047] In an optional embodiment, after determining that the target fan having reached the target negative wind pressure with the first negative wind pressure is in stable reversal and determining the second speed during the current stable reversal, the method further includes performing the following second operation: controlling the target fan to power on and determining the second starting current value when the target fan is powered on; when determining that the target fan in the power-on state achieves stable forward rotation, determining the third speed for stable forward rotation of the target fan and the maximum second current value of the target fan in the process from entering the power-on state to achieving stable forward rotation; determining the test result of the power supply to be tested based on the second speed and the target speed includes: determining the test result of the power supply to be tested based on the second speed, the target speed, the second starting current value, the third speed and the second current value.

[0049] In the above steps, by determining the starting current value of the target fan when it is powered on under the condition of stable reverse rotation under the target negative wind pressure, and the maximum current value of the target fan during the process from power-on to stable forward rotation under the target negative wind pressure, it is possible to determine that the current target fan capacity in the power supply to be tested is insufficient when the starting current value and the maximum current value exceed the maximum current that the power supply to be tested can carry under normal operation, thereby avoiding the problem of power supply damage caused by the current of the target fan in the target negative wind pressure environment exceeding the carrying capacity of the power supply to be tested, thereby improving the test effect.

[0050] In an optional embodiment, after determining the test result of the power supply to be tested based on the second speed, the target speed, the second starting current value, the third speed and the second current value, the method further includes: adjusting the operating mode of the target fan according to a third adjustment method, and repeating the second operation in each operating mode to determine the test result of the power supply to be tested in each operating mode, wherein in different operating modes, the predetermined speed of the target fan, the ambient temperature of the power supply to be tested, and the load of the power supply to be tested are not exactly the same.

[0051] In the above steps, the predetermined speed can be adjusted by the duty cycle of the pulse width modulation (PWM) signal in the driving circuit of the target fan. Exemplarily, when the first negative wind pressure reaches the target negative wind pressure, the predetermined speed of the target fan is a second value, and the ambient temperature is a third value, the load of the power supply to be tested is adjusted each time the target fan is powered on, and the test result of the power supply to be tested is determined based on the second speed, the target speed, the second starting current value, the third speed, and the second current value, wherein the second value is any value included in a plurality of predetermined speeds, and the third value is any value included in a plurality of ambient temperatures.

[0052] In the above steps, by testing the target fan in different working modes, the performance of the power supply to be tested under different conditions can be comprehensively evaluated. By applying the target fan that has passed the comprehensive evaluation to the target power supply, the stability of the power supply can be improved and the service life of the power supply can be extended.

[0053] In an optional embodiment, the method also includes: in each of the working modes, when the target fan achieves stable forward rotation, determining the target air volume of the target fan facing the inside of the test device; determining the test result of the power supply to be tested based on the second speed, the target speed, the second starting current value, the third speed and the second current value includes: determining the test result of the power supply to be tested based on the second speed, the target speed, the second starting current value, the third speed, the second current value and the target air volume.

[0054] In the above steps, the test result of the power supply to be tested is determined based on the second speed, the target speed, the second starting current value, the third speed, the second current value and the target air volume, including: when the second speed is greater than the target speed, the first starting current value or the second starting current value is greater than the target current value, the first current value and the second current value are greater than the target current value, and the target air volume is less than the first air volume, it is determined that the power supply to be tested has failed the test, wherein the target air volume is the minimum air volume required for the power supply to be tested to operate normally under the current working mode.

[0055] In the above steps, illustratively, Figure 6 is a schematic diagram of power supply airflow requirement specifications according to an embodiment of the present application, such as Figure 6 The figure shows the change of the target air volume at different ambient temperatures for each different load condition when the first negative air pressure reaches the target negative air pressure and the predetermined speed of the target fan is a second value. Exemplarily, when any first air volume is less than the corresponding target air volume, it is determined that the power supply to be tested has failed the test.

[0056] In the above steps, by determining the target air volume of the target fan in different working modes and determining the test results based on the target air volume and the first air volume, the problem of poor heat dissipation of the power supply to be tested due to insufficient air volume generated by the target fan is avoided, thereby improving the test effect and the stability of the power supply to be tested.

[0058] In the above steps, exemplarily, the rear damper 408 is first closed and fixed by the rear damper adjusting screw 405, the side damper 406 is opened, and the side damper 406 is preliminarily adjusted by the adjusting knob 411 of the side damper, the rotation speed of the first fan and the opening and closing size and direction of the side damper 406 are adjusted so that the first negative air pressure is greater than the target negative air pressure, the rear damper 408 is opened, and the opening and closing size and direction of the rear damper 408 and the side damper 406 are adjusted so that the first negative air pressure reaches the target negative air pressure, the rear damper 408 is fixed by the rear damper adjusting screw 405, and the side damper 406 is fixed by the fixing knob 413 of the adjusting knob of the side damper.

[0059] In the above steps, by adjusting the first damper, the second damper and the first fan, the negative wind pressure conditions of the target fan in the deployment environment during the application phase can be simulated, thereby achieving performance evaluation of the target fan in the target negative wind pressure scenario and improving the test effect.

[0060] In an optional embodiment, adjusting the first damper and / or the second damper in a first adjustment manner includes: controlling the first damper to close and the second damper to open to obtain an air duct through which the wind generated by the first fan can reach the target fan.

[0061] In the above steps, exemplarily, the rear air damper 408 is closed and fixed by the rear air damper adjusting screw 405, and the side air damper 406 is opened, adjusted by the side air damper adjusting knob 411 and fixed by the fixing knob 413 of the side air damper adjusting knob, thereby forming a reverse environment of the target fan.

[0062] In the above steps, by adjusting the first damper and the second damper, a reverse environment of the target fan is created, thereby realizing a reverse test of the target fan and improving the test effect.
