Description

Technical Field

[0001] This application relates to the field of power supply testing technology, specifically to a performance testing device and method for a liquid-cooled power supply. Background Technology

[0002] Liquid-cooled power supplies are those that operate completely immersed in electronic coolant, making reliability assessment of their performance crucial.

[0003] However, in existing technologies, the performance of liquid-cooled power supplies is typically tested under ambient air conditions. Because the testing environment differs from the operating environment, the measured results cannot accurately reflect the actual performance of the liquid-cooled power supply. Summary of the Invention

[0004] This application provides a performance testing device and method for liquid-cooled power supplies, aiming to address the technical shortcomings of existing technologies where test results for the working performance of liquid-cooled power supplies cannot reflect their actual conditions.

[0005] In a first aspect, this application proposes a performance testing device for a liquid-cooled power supply, the performance testing device comprising:

[0006] The first liquid storage tank is used to store coolant.

[0007] A second liquid storage tank, used to house the test power supply; and

[0008] A piping assembly includes a pipe and a hydraulic element disposed on the pipe, the pipe being disposed between a first liquid storage tank and a second liquid storage tank; wherein, when the performance testing device tests the test power supply, the hydraulic element is activated to allow the first liquid storage tank and the second liquid storage tank to flow the coolant through the pipe, thereby placing the test power supply in the coolant environment of the second liquid storage tank.

[0009] Secondly, this application also proposes a performance testing method for a liquid-cooled power supply, the performance testing method comprising the following steps: placing the test power supply in the second liquid storage tank of a performance testing device for a liquid-cooled power supply; wherein, the performance testing device for a liquid-cooled power supply further comprises a first liquid storage tank and a pipeline assembly; the pipeline assembly comprises a pipeline and a hydraulic element disposed on the pipeline, the pipeline being disposed between the first liquid storage tank and the second liquid storage tank; pre-storing coolant in the first liquid storage tank; activating the hydraulic element to allow the coolant in the first liquid storage tank to flow into the second liquid storage tank, thereby placing the test power supply in the coolant environment of the second liquid storage tank.

[0010] In the technical solution of this application, when the hydraulic components on the pipeline are started, the coolant flows from the first storage tank to the second storage tank through the pipeline, and gradually submerges the test power supply placed in the second storage tank, thereby simulating the actual operating conditions of the test power supply. The performance of the test power supply is tested while it is immersed in the coolant environment in the second storage tank, so that the performance test results of the liquid-cooled power supply can be closer to the actual performance of the test power supply under actual operating conditions, thus making the test results more scientific and convincing.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Figure 1 This is a schematic diagram of the performance testing device for the liquid-cooled power supply proposed in the embodiments of this application. Figure 2 This is a schematic diagram of the performance testing device for the liquid-cooled power supply provided in the embodiments of this application from one perspective. Figure 3 This is a schematic diagram of the performance testing device for the liquid-cooled power supply provided in an embodiment of this application, viewed from another perspective. (Refer to...) Figures 1 to 3 As shown in the illustration, this application also proposes a performance testing device for a liquid-cooled power supply. This performance testing device includes:

[0025] The first liquid storage tank 110 is used to store coolant;

[0026] The second liquid storage tank 120 is used to house the test power supply 10; and

[0027] The pipeline assembly 130 includes a pipeline 131 and a hydraulic element 132 disposed on the pipeline 131. The pipeline 131 is disposed between the first liquid storage tank 110 and the second liquid storage tank 120. When the performance testing device tests the test power supply 10, the hydraulic element 132 is activated to allow the coolant to flow between the first liquid storage tank 110 and the second liquid storage tank 120 through the pipeline 131, thereby placing the test power supply 10 in the coolant environment of the second liquid storage tank 120.

[0028] In this embodiment, when the hydraulic component 132 on the pipeline is activated, the coolant flows from the first reservoir 110 through the pipeline 131 to the second reservoir 120, gradually submerging the test power supply placed in the second reservoir 120. This simulates the actual operating conditions of the test power supply. The test power supply is immersed in the coolant environment in the second reservoir 120, and its working performance is tested. This makes the test results closer to the actual performance of the test power supply under actual operating conditions, thus making the test results more scientific and convincing.

[0029] In practical applications, the specific type of coolant can be selected according to the medium environment required by the test power supply 10, and this application does not limit it.

[0030] It should be noted that the first liquid storage tank 110 has a receiving cavity for storing coolant, and the second liquid storage tank 120 has a test cavity for storing the test power supply 10. The pipe 131 is connected to the receiving cavity and the test cavity, respectively.

[0031] In some embodiments, the second liquid storage tank 120 may also have an opening (not shown) communicating with the test chamber. This opening may be located at the top of the second liquid storage tank 120. This opening facilitates the insertion or removal of the test power supply 10 from the test chamber.

[0032] Furthermore, since the coolant is highly volatile in some possible embodiments, the second reservoir 120 may also have a cover (not shown) for closing the opening to reduce coolant evaporation loss. During testing, the opening is closed by the cover.

[0033] In one possible embodiment, the cover can be rotatably or slidably connected to the body of the second liquid storage tank 120 adjacent to the opening, thereby opening / closing the opening by rotating or sliding the cover. In this case, the opening / closing of the opening can be manually operated or mechanically automated. Mechanical automation can be achieved by fixing the cover to a piston of a cylinder, thereby driving the opening / closing of the opening via the cylinder.

[0034] It is understood that the cover can also be installed separately from the second liquid storage tank 120. When it is necessary to open the opening, the tester removes the cover, and when it is necessary to close the opening, the tester places the cover over the opening. Of course, the cover can also be connected to a suspension mechanism to automatically open / close the opening. The specific details of the suspension mechanism can be found in existing technology and will not be described in detail in this application.

[0035] In some embodiments, the second liquid storage tank 120 may also have multiple test interfaces (not shown). These test interfaces may include, for example, an AC input interface, a DC output interface, and a communication and detection line interface. Correspondingly, the testing device may also include an AC test input power supply and a DC test input power supply. The AC input interface is used to connect to the AC test input power supply. The DC output interface is used to connect to the DC test input power supply.

[0036] The parameters and number of AC and DC test input power supplies can be set according to specific test requirements. For example, the number of AC test input power supplies can be 5, with parameters such as withstand voltage of 380V and withstand current of 160A. The number of DC test input power supplies can be 2, with parameters such as withstand voltage of 80VDC and withstand current of 600A.

[0037] The communication and detection line interface is used to connect to an external data acquisition unit to collect the performance parameters of the test power supply during the test.

[0038] Furthermore, the second liquid storage tank 120 may also be provided with a sealed connector for the test wire to pass from inside the test chamber to outside the second liquid storage tank 120. In one possible embodiment, the second liquid storage tank 120 may also be provided with a sealing port (not shown) as a reserved interface for wire threading if necessary.

[0039] In some embodiments, the first liquid storage tank 110 and the second liquid storage tank 120 may both have flat bottoms, and the first liquid storage tank 110 and the second liquid storage tank 120 may both be placed on a flat platform or ground. Alternatively, the performance testing apparatus may also include a frame 200. The frame 200 is used to place the first liquid storage tank 110 and the second liquid storage tank 120.

[0040] When designing the size and shape of the test chamber of the second liquid storage tank 120, the test chamber needs to have sufficient capacity after the test power supply is placed in it to facilitate the flow of coolant and prevent collisions between the test power supply and the second liquid storage tank 120. Typically, the test power supply is placed into and removed from the test chamber using a crane basket (not shown). Of course, the test power supply can also be placed and removed by testing personnel.

[0041] In some embodiments, both the second coolant tank 120 and the first coolant tank 110 may be provided with drain ports for discharging coolant when no testing is being performed, and the discharged coolant is introduced into a coolant recovery tank. Generally, the drain ports may be equipped with manual or automatic switches.

[0042] Typically, the testing apparatus may also include a cooling system (not shown). The cooling system can be positioned above the first storage tank 110. The cooling system may include a fan. After the test is completed, the fan starts to dry the test power supply after it has been hoisted to the corresponding position on the cooling system via a basket. Furthermore, to reduce coolant loss, a recovery pipe 131 is provided around the cooling system, which introduces coolant into the first storage tank 110, thus reducing testing costs.

[0043] In this embodiment, the hydraulic element 132 may include a pump and / or a compressor.

[0044] To effectively simulate the actual operating conditions of the test power supply 10, this application further provides an apparatus for performing performance testing of the test power supply 10 in a flowing coolant. As an optional implementation of the above embodiments, refer to... Figure 1As shown, the pipe 131 may include a first pipe 1311 and a second pipe 1312. The hydraulic element 132 is disposed on the first pipe 1311. The first liquid storage tank 110 is provided with a first drain port 110a and a first inlet port 110b. The second liquid storage tank 120 is provided with a second drain port 120b and a second inlet port 120a. The first pipe 1311 is connected to the first drain port 110a and the second inlet port 120a respectively, so that when the hydraulic element 132 is activated, the coolant in the first storage tank 110 flows through the first drain port 110a into the first pipe 1311, and the coolant entering the first pipe 1311 flows through the second inlet port 120a into the second storage tank 120; the first inlet port 110b is connected to the second drain port 120b through the second pipe 1312, so that the coolant in the second storage tank 120 flows through the second drain port 120b into the second pipe 1312, and the coolant entering the second pipe 1312 flows back to the first storage tank 110 through the first inlet port 110b, thereby realizing the circulation of the coolant. In the above embodiment, the coolant circulates within the first reservoir 110 and the second reservoir 120 through the first pipe 1311 and the second pipe 1312 to simulate the actual operating conditions of the test power supply and to better reflect the performance of the test power supply under actual operating conditions.

[0045] In some embodiments, the second drain port 120b may be located near the upper part of the first storage tank 110, and the first inlet port 110b may be located near the lower part of the second storage tank 120 or at the bottom of the second storage tank 120. When the hydraulic element 132 on the first pipe 1311 is activated, the hydraulic element 132 transports the coolant in the first storage tank 110 to the second storage tank 120 through the first pipe 1311, and the coolant level in the second storage tank 120 gradually rises. When the coolant level in the second storage tank 120 reaches the position of the second drain port 120b, it overflows into the first storage tank 110 through the second pipe 1312, thereby circulating the coolant. This allows the test power supply to be tested in a flowing coolant environment, while reducing coolant loss and thus reducing test costs.

[0046] As an optional implementation of the above embodiments, combined with Figure 5 and Figure 6As shown, there can be multiple second liquid inlets 120a, and these multiple second liquid inlets 120a are evenly arranged on the second liquid storage tank 120. Generally, the second liquid inlets 120a are located at the bottom of the second liquid storage tank 120. When the hydraulic element 132 is activated, the hydraulic element 132 inputs the coolant from the first liquid storage tank 110 into the second liquid storage tank 120 through multiple second liquid inlets 120a evenly arrayed at the bottom of the second liquid storage tank 120, thereby ensuring that the temperature in the environment where the test power supply 10 is located remains uniform and improving the accuracy of the test results.

[0047] The specific number of the second liquid inlet 120a can be set according to testing needs, for example... Figure 6 In the illustrated embodiment, there are three second liquid inlets 120a. These three second liquid inlets 120a are arranged in an equilateral triangular array. Alternatively, there may be two second liquid inlets 120a, arranged symmetrically about the center line of the second liquid storage tank 120. Furthermore,... Figure 5 In the embodiment shown, there are four second liquid inlets 120a, and the four second liquid inlets 120a are arranged in a square array.

[0048] In some embodiments, there may be multiple second drain ports 120b, and these ports are evenly distributed on the second liquid storage tank 120. Generally, the second drain ports 120b are located at the top of the second liquid storage tank 120. When the coolant level in the second liquid storage tank 120 reaches the position of the second drain port 120b, it overflows into the first liquid storage tank 110 through the second pipe 1312. Evenly distributing multiple second drain ports 120b on the second liquid storage tank 120 allows coolant to overflow from the multiple second drain ports 120b through the second pipe 1312, ensuring a uniform temperature of the coolant at the test power supply 10. For example, if the second liquid storage tank 120 is cylindrical, the second drain ports 120b are evenly spaced along the circumference of the second liquid storage tank 120. Alternatively, if the second liquid storage tank 120 is constructed with four side walls, the second drain ports 120b can be respectively disposed on the four side walls.

[0049] As an optional implementation of the above embodiments, such as Figure 1 and 3 As shown, the piping assembly 130 may further include a flow rate valve 133. The flow rate valve 133 is disposed in the first pipe 1311 and / or the second pipe 1312 to control the flow rate of the coolant. The flow rate valve 133 can be a manual valve or a solenoid valve. By controlling the flow rate of the coolant, the volume of the coolant in the second reservoir 120 can be controlled and / or the temperature of the coolant can be adjusted to maintain the coolant within a reasonable liquid level and temperature range in the second reservoir 120.

[0050] In one possible embodiment, a flow rate valve 133 is disposed on the second pipe 1312 to control the speed at which coolant flows out of the second storage tank 120, so as to dynamically adjust the level and temperature of coolant in the second storage tank 120.

[0051] As an optional implementation of the above embodiments, such as Figure 4 As shown, the performance testing device may further include a controller 190. The controller 190 is electrically connected to the flow rate valve 133. The controller 190 is configured to adjust the opening of the flow rate valve 133 based on the temperature of the coolant. The flow rate valve 133 may be an electromagnetic flow rate valve. By obtaining the temperature of the coolant, the opening of the electromagnetic flow rate valve 133 is adjusted to regulate the temperature within the second reservoir 120.

[0052] In some embodiments, the performance testing apparatus may further include a temperature sensor 180 for measuring the temperature of the coolant in the second storage tank 120. Generally, the temperature sensor 180 is disposed on the cavity wall of the test chamber of the second storage tank 120.

[0053] For example, when the coolant temperature exceeds the first preset temperature value, the controller 190 controls the flow rate valve 133 to increase its opening, causing the coolant in the second reservoir 120 to be discharged from the second reservoir 120 more quickly through the second pipe 1312. In this case, the controller 190 can control the coolant in the first reservoir 110 to cool down (generally by controlling the temperature regulating structure 111 in the first reservoir 110 to cool down the coolant), and at the same time control the rotation speed of the hydraulic element 132 to increase the speed of the hydraulic element 132, so as to input the cooled coolant into the second reservoir 120, thereby achieving the purpose of lowering the coolant temperature in the second reservoir 120.

[0054] For example, when the coolant temperature is lower than the second preset temperature value, the controller 190 controls the flow rate valve 133 to increase its opening, so that the coolant in the second reservoir 120 is discharged from the second reservoir 120 more quickly through the second pipe 1312. In this case, the controller 190 can control the coolant in the first reservoir 110 to heat up (generally by controlling the temperature regulating structure 111 in the first reservoir 110 to heat up the coolant, and at the same time control the rotation speed of the hydraulic element 132 to increase the speed of the hydraulic element 132, so as to input the heated coolant into the second reservoir 120, thereby achieving the purpose of raising the coolant temperature in the second reservoir 120).

[0055] As an optional implementation of the above embodiments, such as Figure 1As shown, the performance testing device may further include a third liquid storage tank 140 and an overflow pipe 131. The third liquid storage tank 140 is provided with a third liquid inlet 140a. The second liquid storage tank 120 is also provided with a third liquid outlet 120c, which is located above the second liquid outlet 120b in the height direction of the second liquid storage tank 120. The overflow pipe 131 is connected to the third liquid outlet 120c and the third liquid inlet 140a respectively. Since the test power supply 10 needs to be tested within a relatively stable temperature range, there is a possibility that more coolant may be injected into the second liquid storage tank 120 during the temperature adjustment process (for example, more low-temperature coolant needs to be injected when the temperature is too high; or more high-temperature coolant needs to be injected when the temperature is too low). At this time, the liquid level in the second liquid storage tank 120 will rise, and the coolant may overflow the second liquid storage tank 120. Therefore, this embodiment of the application provides a third liquid storage tank 140 and an overflow pipe 150. When the coolant level reaches the position of the third drain port 120c on the second reservoir 120, the coolant flows through the overflow pipe 150 into the third reservoir 140 to avoid overflow of coolant during the temperature regulation process, thus effectively saving coolant.

[0056] As an optional implementation of the above embodiments, such as Figure 1 As shown, the performance testing device may further include a replenishment pipe 160 and a replenishment switch 161 disposed on the replenishment pipe 160. The third liquid storage tank 140 may be provided with a fourth drain port (not shown). The first liquid storage tank 110 may be provided with a fourth inlet port (not shown). The replenishment pipe 160 is connected to the fourth drain port and the fourth inlet port respectively. When the replenishment switch 161 is in the activated state, the coolant in the third liquid storage tank 140 is transported to the replenishment pipe 160 through the fourth drain port, and the coolant entering the replenishment pipe 160 flows to the first liquid storage tank 110 through the fourth inlet port to replenish the coolant in the first liquid storage tank 110.

[0057] It is understood that coolant overflow from the second reservoir 120 would reduce the volume of coolant in both the second and first reservoirs 110. Therefore, to ensure the smooth conduct of the test, a third reservoir 140 is installed on top of the first reservoir 110, and the third reservoir 140 and the first reservoir 110 are connected via a replenishment pipe 160. A replenishment switch 161 is provided on the replenishment pipe 160 so that, when activated, coolant from the third reservoir 140 can flow through the replenishment pipe 160 to the first reservoir 110, replenishing the coolant in the first reservoir 110 and ensuring that the coolant levels in both the first and second reservoirs 120 are within a reasonable range.

[0058] Generally, the fluid replenishment switch 161 can be an electromagnetic switch. For example... Figure 4 As shown, the replenishment switch 161 can also be electrically connected to the controller 190. The replenishment switch 161 can also be a standard manual valve.

[0059] In some embodiments, the performance testing apparatus further includes a replenishment tank, which may be connected to the first storage tank 110 and / or the third storage tank 140 respectively, for the purpose of recovering coolant and / or replenishing coolant.

[0060] As an optional implementation of the above embodiments, the performance testing device for the liquid-cooled power supply may further include a liquid level sensor 170. The liquid level sensor 170 may be disposed on the second liquid storage tank 120 and used to measure the liquid level of the coolant in the second liquid storage tank 120. The liquid level sensor 170 can reflect the liquid level height of the coolant in the second liquid storage tank 120.

[0061] In one possible embodiment, the level sensor 170 may be electrically connected to the controller 190. The controller 190 is configured to adjust the rotational speed of the hydraulic element 132 and / or the opening of the flow valve 133 based on the height of the level sensor 170 to maintain the liquid level in the second reservoir 120 within a reasonable range so that the test power supply 10 can be fully immersed in the coolant.

[0062] For example, during the test, when the liquid level in the second storage tank 120 is lower than the first preset value, the controller 190 controls the hydraulic element 132 to increase its rotation speed, thereby increasing the speed at which the coolant enters the second storage tank 120; when the liquid level in the second storage tank 120 is higher than the second preset value, the controller 190 controls the hydraulic element 132 to decrease its rotation speed and controls the opening of the flow valve 133 to increase, so as to discharge the coolant in the second storage tank 120 into the first storage tank 110.

[0063] As an optional implementation of the above embodiments, the performance testing device for the liquid-cooled power supply may further include a temperature control structure 111. The temperature control structure 111 is disposed on the first liquid storage tank 110 and is used to adjust the temperature of the coolant.

[0064] The temperature control structure 111 may include a heating structure 1111 and a cooling structure 1112.

[0065] The heating structure 1111 can heat the coolant by electric heating. For example, the heating structure 1111 includes an electric heating wire, an electric heating plate, or an electric heating rod disposed in the first storage tank 110. Alternatively, the heating structure 1111 may also include a first heat exchange tube and a heating system, wherein the heating system heats the coolant by injecting a heating medium into the first heat exchange tube.

[0066] The cooling structure 1112 may include a second heat exchange tube and a cooling system. The cooling system cools the coolant by injecting refrigerant into the second heat exchange tube. Both the first and second heat exchange tubes may be arranged in a spiral tube structure inside the first liquid storage tank 110 or on the wall of the first liquid storage tank 110.

[0067] As an optional embodiment of the above embodiments, the performance testing device for the liquid-cooled power supply may further include a stirring mechanism 112, which is disposed in the first liquid storage tank 110 and is used to stir the coolant.

[0068] The stirring mechanism 112 is used to increase the flow of coolant in the first storage tank 110 so that the temperature of coolant is uniform in the first storage tank 110.

[0069] Generally, when the temperature regulating structure 111 adjusts the temperature of the coolant, in order to ensure the uniformity of the coolant temperature, the stirring mechanism 112 starts to start, so that the coolant in the first storage tank 110 is heated or cooled evenly, and the temperature of the coolant flowing into the second storage tank 120 is uniform, thus ensuring the reliability of the test results.

[0070] The stirring mechanism 112 may include an impeller and a shaft for driving the impeller to rotate, the shaft being connected to a motor externally located in the first liquid storage tank 110.

[0071] In one possible embodiment, the temperature of the coolant flowing out of the first reservoir 110 can be controlled between -5 degrees Celsius and 70 degrees Celsius. By adjusting the temperature of the coolant in the first reservoir 110, primarily adjusting the temperature of the coolant in the second reservoir 120, two advantages are achieved: First, temperature tests can be conducted, i.e., the test power supply 10 can be tested under different temperature conditions to obtain the performance parameters of the test power supply 10 under different temperature conditions as a function of temperature. Second, when the test environment requires maintaining a relatively constant temperature range, the test power supply 10 will also generate heat during testing, causing the temperature of the test environment to rise. In this case, by adjusting the temperature of the coolant, the test environment can be maintained within the relatively constant temperature range required for testing. For example, the relatively constant temperature range required for the test environment can be around 20 degrees Celsius. When the coolant temperature rises to 30 degrees Celsius due to the heat generated by the test power supply 10, the cooling structure 1112 can be activated to cool the coolant, adjusting the temperature to around 20 degrees Celsius, such as between 18 and 22 degrees Celsius.

[0072] Based on the performance testing device proposed in some or all of the above embodiments, this application also proposes a performance testing method for a liquid-cooled power supply. For example... Figure 7 As shown, the performance testing method includes:

[0073] S100, the test power supply 10 is placed in the second liquid storage tank 120 of the liquid-cooled power supply performance testing device; wherein, the liquid-cooled power supply performance testing device further includes a first liquid storage tank 110 and a pipe assembly 130; the pipe assembly 130 includes a pipe 131 and a hydraulic element 132 disposed on the pipe 131, and the pipe 131 is disposed between the first liquid storage tank 110 and the second liquid storage tank 120;

[0074] S200, coolant is pre-stored in the first storage tank 110;

[0075] S300, activate the hydraulic element 132 to allow the coolant in the first storage tank 110 to flow into the second storage tank 120, thereby placing the test power supply 10 in the coolant environment of the second storage tank 120.

[0076] In this embodiment, after the test power supply 10 is placed into the second liquid storage tank 120, the hydraulic element 132 on the pipe 131 connecting the first liquid storage tank 110 and the second liquid storage tank 120 is activated, so that coolant is introduced into the second liquid storage tank 120 through the pipe 131. This allows the test power supply 10 to be placed in a coolant environment during testing, realistically simulating the actual operating conditions of the test power supply 10. In this technical solution, when the hydraulic element 132 on the pipe is activated, the coolant flows from the first liquid storage tank 110 through the pipe 131 to the second liquid storage tank 120, gradually submerging the test power supply placed in the second liquid storage tank 120. This simulates the actual operating conditions of the test power supply 10. By testing the performance of the test power supply 10 while it is immersed in the coolant environment of the second liquid storage tank 120, the test results are closer to the actual performance of the test power supply under real operating conditions, making the test results more scientific and convincing.

[0077] Generally speaking, there is no strict order between steps S100 and S200. For example, during testing, step S100 can be executed before step S200, or step S200 can be executed before step S100, or steps S100 and S200 can be executed simultaneously.
