[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0059] It should be noted that the directional words such as "upper end, lower end, left side, right side" described below are all defined based on the drawings in the specification.

[0060] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The server heat dissipation testing device provided in the embodiment of the present invention includes a testing housing 20 , a sealing slider 30 and a sliding control assembly 40 .

[0061] The test shell 20 has an inner cavity 21, and the sealing slider 30 is slidably disposed in the inner cavity 21. The sealing slider 30 is configured to maintain a sealed contact with the inner wall of the test shell 20 during the sliding process relative to the test shell 20, so that the sealing slider 30 and the test shell 20 form a sealed test cavity 22 with adjustable size. The sliding control component 40 is connected to the sealing slider 30. The sliding control component 40 can be disposed in the inner cavity 21 of the test shell 20. The sliding control component 40 is used to control the sliding of the sealing slider 30 in the inner cavity 21 to adjust the size of the sealed test cavity 22.

[0062] It can be seen that the sealed test chamber 22 is located in the inner chamber 21 of the test shell 20. The sealed test chamber 22 is formed by the sealing slider 30 and the test shell 20. Since the sealing slider 30 maintains sealed contact with the inner wall of the test shell 20 during the sliding process relative to the test shell 20, the sealed test chamber 22 can always maintain sealing.

[0063] During testing, the sealing slider 30 is controlled by the sliding control component 40 to slide along the inner wall of the test shell 20, and the size of the sealed test chamber 22 in the inner cavity 21 of the test shell 20 is adjusted so that the volume of the sealed test chamber 22 matches the volume of the simulated server, thereby realizing simulated testing of servers of different volumes.

[0064] The server heat dissipation test device configured in this way has the following beneficial effects:

[0065] Compared with the conventional method of simulating dummy loads of different lengths, in which the operating steps are too complicated, the labor intensity of operators is high, and the test efficiency is low, the server heat dissipation test device provided in the embodiment of the present invention realizes the simulation of servers of different sizes by setting a fixed test shell 20, a sealing slider 30 that can slide freely along the inner wall of the test shell 20, and a sliding control component 40 that controls the sealing slider 30 to slide along the inner wall of the test shell 20. In addition, the sealed test chamber 22 is always in a sealed state while performing the simulation, which simplifies the operating steps when simulating servers of different volumes, reduces the labor intensity of operators, and improves the efficiency of server simulation testing.

[0066] Please also read Figure 6 and Figure 7 In order to facilitate the real simulation of the server bearing different loads during operation, the server heat dissipation test device also includes a circulating water tank 50, which is used to supply circulating liquid to the sealed test chamber 22. A heating component 51 is provided inside the circulating water tank 50, and the heating component 51 is used to heat the circulating liquid in the circulating water tank 50.

[0067] Of course, according to actual needs, the heating component 51 can be a heating elbow or a heating coil structure, and the heating elbow or the heating coil is arranged inside the circulating water tank 50. The heating elbow or the heating coil is a sealed structure and the heating temperature can be adjusted. The heating elbow or the heating coil is used to heat the circulating liquid in the circulating water tank 50 to the target temperature, so as to provide heat for the sealed test cavity 22 (simulated server).

[0068] In this way, the heating elbow or heating coil is started to heat the circulating fluid in the circulating water tank 50 to the target simulation temperature, thereby achieving a true simulation of the server bearing different loads during operation.

[0069] Taking into account the traditional adjustment of the dummy load to different lengths, when the dummy load is pulled out or penetrated into the coolant, the volume inside the shell will change, causing the liquid level in the shell to change greatly before and after the dummy load is adjusted. This will cause the coolant to be unable to completely immerse the dummy load located on the upper layer of the shell, affecting the test results and causing a large error in the final test results.

[0070] To this end, the server heat dissipation testing device further includes a balancing water tank 60 , which is connected to the circulating water tank 50 via a liquid replacement valve 61 , and is used to maintain the liquid level of the circulating liquid in the circulating water tank 50 .

[0071] It can be seen that by setting up the balancing water tank 60 connected to the circulating water tank 50, it is possible to arbitrarily adjust the amount of circulating liquid in the sealed test chamber 22 in the test shell 20 while avoiding affecting the liquid level in the circulating water tank 50. In this way, it can be ensured that the liquid level in the circulating water tank 50 is always higher than the height of the heating component 51 in the circulating water tank 50, thereby ensuring the safety of heating, and also achieving complete isolation of the heating liquid in the circulating water tank 50 from the cooling liquid in the balancing water tank 60, thereby ensuring that the circulating liquid is completely unaffected by the volume of the sealed test chamber 22 during circulation, thereby ensuring the accuracy of the test results and reducing the test errors.

[0072] Moreover, in order to facilitate the installation of the balancing water tank 60 and the circulating water tank 50, the server heat dissipation testing device also includes a testing cabinet 10, and a heating chamber 13 is provided inside the testing cabinet 10. The heating chamber 13 is located at the bottom of the testing cabinet 10, and the circulating water tank 50 and the balancing water tank 60 are both fixedly connected to the inside of the heating chamber 13.

[0073] Furthermore, considering that the entire channel is a sealed structure during the entire circulation process of the circulating liquid, in order to ensure the stability of the internal pressure, a balancing air valve 62 is provided on the top wall of the balancing water tank 60. The balancing air valve 62 is used to open when the pressure inside the balancing water tank 60 reaches a threshold value, and an air guide groove 131 is provided on the outer wall of the heating chamber 13. This arrangement ensures that the pressure inside the balancing water tank 60 and the circulating water tank 50 is always within a safe and stable range, thereby ensuring the circulation of the circulating liquid in the sealed test chamber 22 and realizing a true simulation of the server bearing different loads during operation.

[0074] In some embodiments, there are two sealing sliders 30 , and the two sealing sliders 30 are disposed in the inner cavity 21 of the test housing 20 relative to each other. The two sealing sliders 30 and the test housing 20 form a sealed test cavity 22 .

[0075] That is to say, corresponding to one sealing test cavity 22, two groups of sealing sliders 30 are provided, and the two groups of sealing sliders 30 can achieve the purpose of adjusting the size of the sealing test cavity 22 by sliding relative to the inner wall of the test shell 20. The sliding of the two groups of sealing sliders 30 can be synchronous or asynchronous.

[0076] In order to ensure that the sealing slider 30 maintains sealed contact with the inner wall of the test shell 20 during the sliding process relative to the inner wall of the test shell 20, a sealing rubber ring 31 is provided on any sealing slider 30, and the sealing rubber ring 31 is used to abut against the inner wall of the test shell 20 to seal the gap between the corresponding sealing slider 30 and the inner wall of the test shell 20.

[0077] For example, installation grooves can be set on the upper and lower end surfaces of the sealing slider 30, and the sealing rubber ring 31 is installed in the corresponding installation grooves. The thickness of the sealing rubber ring 31 should be greater than the depth of the corresponding installation groove. In this way, when the sealing slider 30 is assembled in the inner cavity 21 of the test shell 20, the sealing rubber ring 31 is pressed against the inner wall of the test shell 20, and the elasticity of the sealing rubber ring 31 is used to make the sealing rubber ring 31 press against the inner wall of the test shell 20 after a certain degree of compression deformation. In this way, the gap between the corresponding sealing slider 30 and the inner wall of the test shell 20 can be sealed, ensuring that the sealing slider 30 maintains sealing contact with the inner wall of the test shell 20 during the sliding process relative to the inner wall of the test shell 20.

[0078] It should be noted that after the assembly is completed, the sealing slider 30 squeezes the sealing rubber ring 31, and the sealing rubber ring 31 is flattened after being subjected to force, and the two ends of the sealing rubber ring 31 are tightly fitted to the inner wall of the sealing slider 30 and the test housing 20. The sealing rubber ring 31 blocks the gap between the sealing slider 30 and the test housing 20, thereby preventing the circulating fluid in the sealed test cavity 22 from leaking from the gap between the sealing slider 30 and the test housing 20. On the other hand, the material of the sealing rubber ring 31 is set to be rubber. When the sealing rubber ring 31 and the inner wall of the test housing 20 are in contact, there is a large friction between the sealing rubber ring 31 and the inner wall of the test housing 20. This friction can ensure the stability of the sealing slider 30 when the circulating fluid is introduced into the sealed test cavity 22. Only when the sliding control component 40 provides a driving force can the friction be overcome, thereby driving the sealing slider 30 to slide relative to the inner wall of the test housing 20.

[0079] In order to facilitate the circulation of the circulating liquid in the circulating water tank 50 in the sealed test chamber 22 , the server heat dissipation test device further includes a liquid supply pipe assembly 70 and a liquid return pipe assembly 80 .

[0080] Among them, the liquid supply pipe assembly 70 is connected to the circulating water tank 50 and the sealing slider 30 on the first side, and the liquid supply pipe assembly 70 is used to transport circulating liquid to the sealing test cavity 22; the liquid return pipe assembly 80 is connected to the circulating water tank 50 and the sealing slider 30 on the second side, and the liquid return pipe assembly 80 is used to supply the circulating liquid in the sealing test cavity 22 to flow back to the circulating water tank 50.

[0081] That is to say, the circulating liquid in the circulating water tank 50 is transported to the sealing test chamber 22 through the liquid supply pipe assembly 70, and then flows back to the circulating water tank 50 through the liquid return pipe assembly 80, thereby forming a circulation of circulating liquid between the circulating water tank 50-liquid supply pipe assembly 70-sealing test chamber 22-return liquid pipe assembly 80-circulating water tank 50, thereby realizing a true simulation of the server bearing different loads during operation.

[0082] Specifically, the server heat dissipation testing device also includes a test cabinet 10, a test chamber 11 is provided inside the test cabinet 10, the test chamber 11 is located above the heating chamber 13, and at least two groups of test shells 20 are arranged side by side along a first direction in the test chamber 11. Any group of test shells 20 includes at least two test shells 20 arranged at equal intervals along a second direction, wherein the second direction is perpendicular to the first direction, and any test shell 20 extends outward through the outer wall of the test cabinet 10.

[0083] Accordingly, at least two liquid supply pipe assemblies 70 are provided, and at least two liquid return pipe assemblies 80 are provided. The number of both the liquid supply pipe assemblies 70 and the liquid return pipe assemblies 80 is the same as the number of groups of the test housings 20 .

[0084] It should be noted that the first direction may be as follows: Figure 3 The X-axis direction shown, the second direction can be as follows Figure 3 The Y-axis direction is shown.

[0085] Taking two groups of test shells 20 as an example, the two groups of test shells 20 are arranged along the Figure 3 The four test housings 20 are arranged side by side in the X-axis direction as shown in FIG. Figure 3 In other words, the eight test housings 20 are arranged in two rows in the test chamber 11 .

[0086] Specifically, any liquid supply pipe assembly 70 includes a first connecting pipe 71 and four liquid supply pipe bodies 72. The liquid supply pipe body 72 is connected to the sealing slider 30 located on the first side in the corresponding test shell 20. The liquid supply pipe body 72 extends inward through the outer wall of the corresponding sealing slider 30. The first connecting pipe 71 is used to connect the circulating water tank 50 and each liquid supply pipe body 72.

[0087] It can be seen that the liquid supply pipe body 72 is fixedly connected to the outer wall of the corresponding sealing slider 30, the first connecting pipe 71 is fixedly connected to the output end of each liquid supply pipe body 72, the liquid supply pipe body 72 passes through the outer wall of the sealing slider 30 and extends inward to transport circulating liquid to the interior of the sealing test cavity 22, and the first connecting pipe 71 connects the four liquid supply pipe bodies 72 arranged in the vertical direction to each other. In this way, the circulating liquid in the circulating water tank 50 can be transported to each sealing test cavity 22 through the first connecting pipe 71 and the four liquid supply pipe bodies 72.

[0088] Any liquid return pipe assembly 80 includes a second connecting pipe 81 and four liquid return pipe bodies 82. The liquid return pipe body 82 is connected to the sealing slider 30 located on the second side of the corresponding test shell 20. The liquid return pipe body 82 extends inward through the outer wall of the corresponding sealing slider 30. The second connecting pipe 81 is used to connect the circulating water tank 50 and each liquid return pipe body 82.

[0089] It can be seen that the liquid return pipe body 82 is fixedly connected to the outer wall of the corresponding sealing slider 30, and the second connecting pipe 81 is fixedly connected to the output end of each liquid return pipe body 82. The liquid return pipe body 82 passes through the outer wall of the sealing slider 30 and extends inward, so that the circulating liquid inside the sealing test cavity 22 flows out of the sealing test cavity 22 through the liquid return pipe body 82. The second connecting pipe 81 connects the four liquid return pipe bodies 82 arranged in the vertical direction to each other. In this way, the circulating liquid in each sealing test cavity 22 can flow back to the second connecting pipe 81 through the corresponding liquid return pipe body 82, and finally flow back to the circulating water tank 50.

[0090] In order to facilitate the connection between the liquid supply pipe body 72 and the corresponding sealing slider 30, the liquid supply pipe body 72 can be set as a telescopic pipe body or a linear bearing can be set between the liquid supply pipe body 72 and the corresponding sealing slider 30 to achieve the sliding movement of the sealing slider relative to the liquid supply pipe body 72. The connection method of the liquid return pipe body 82 and the corresponding sealing slider 30 refers to the connection method of the liquid supply pipe body 72 and the corresponding sealing slider 30.

[0091] In order to facilitate the communication between the circulating water tank 50 and the first connecting pipe 71 and the second connecting pipe 81, at least two pairs of circulating pipes 52 are provided on the circulating water tank 50. Any pair of circulating pipes 52 is connected to the corresponding first connecting pipe 71 and the second connecting pipe 81. Any circulating pipe 52 is connected to a circulating pump 53. The circulating pump 53 is used to provide power so that the circulating liquid in the circulating water tank 50 is transported to the corresponding sealing test cavity 22 through the corresponding circulating pipe 52, the first connecting pipe 71 and the liquid supply pipe body 72, and flows back to the circulating water tank 50 through the corresponding return pipe body 82, the second connecting pipe 81 and the circulating pipe 52, thereby forming a circulating flow of the circulating liquid in the sealing test cavity 22.

[0092] In this way, during the test, the circulation pump 53 is first controlled to be turned on, and the circulating liquid is delivered to the sealed test chamber 22 in the corresponding test shell 20 through the first connecting pipe 71 and the liquid supply pipe body 72. While delivering the circulating liquid, the sealing slider 30 is controlled to move along the inner wall of the test shell 20 through the sliding control component 40, and the size of the sealed test chamber 22 inside the test shell 20 is adjusted to make the volume of the sealed test chamber 22 consistent with the volume of the simulated server, thereby realizing the simulation test of servers of different volumes; during the adjustment process, the switch of the control liquid exchange valve 61 is opened so that the water in the balancing water tank 60 can flow smoothly into the circulating water tank 50, so that the liquid level in the circulating water tank 50 is always higher than the height of the heating elbow, and the balance control of the circulating liquid amount in the circulating water tank 50 is completed, ensuring the normal circulation of the circulating liquid during the test process. When the circulating liquid is continuously circulating in the sealed test chamber 22 in the test shell 20, the heating elbow is started to heat the circulating circulating liquid to the target simulation temperature, thereby realizing a true simulation of the server bearing different loads during operation.

[0093] In some embodiments, a cooling chamber 12 is further provided inside the test cabinet 10 , and the cooling chamber 12 is located above the test chamber 11 . The outer wall of the cooling chamber 12 is provided with a heat dissipation groove 121 , and the heat dissipation groove 121 is used to dissipate the heat in the cooling chamber 12 to the outside of the test cabinet 10 .

[0094] Please also read Figure 3 and Figure 8 In order to facilitate the heat dissipation simulation of the server, the interior of the test chamber 11 is filled with thermally conductive silicone oil, and the server heat dissipation test device also includes a cooler 90 and a cooling pump 100. The cooler 90 is arranged in the cooling chamber 12, and the cooler 90 is used to cool the thermally conductive silicone oil. The output end of the cooler 90 is connected to a drain pipe 91, and the drain pipe 91 passes through the cooling chamber 12 and extends to the inside of the test chamber 11; the cooling pump 100 is connected to the cooler 90, and the input end of the cooling pump 100 is connected to a liquid extraction pipe 101, and the liquid extraction pipe 101 passes through the cooling chamber 12 and extends to the bottom of the test chamber 11. The cooler 90 is connected to the inside of the cooling pump 100, and the cooling pump 100 and the liquid extraction pipe 101, as well as the cooler 90 and the drain pipe 91 are symmetrically distributed about the central axis of the cooling chamber 12.

[0095] In this way, by monitoring the temperature changes in the sealed test chamber 22, when the temperature in the sealed test chamber 22 reaches the set threshold, the cooling pump 100 is started, and the thermal conductive silicone oil in the test chamber 11 is pumped into the cooler 90 through the suction pipe 101 to cool the thermal conductive silicone oil. The cooled thermal conductive silicone oil is discharged into the test chamber 11 again through the discharge pipe 91, thereby realizing the circulating cooling of the thermal conductive silicone oil and ensuring the test of the heat dissipation effect of the simulated server.

[0096] It can be understood that the present invention adopts a test chamber 11, a cooling chamber 12 and a heating chamber 13 in the test cabinet 10, and the cooling chamber 12 and the heating chamber 13 are respectively arranged on the upper and lower sides of the test chamber 11. This design can better simulate the heating and heat dissipation of the server in the actual working environment, and can more effectively organize the airflow, so that the cold air and the hot air can be effectively separated, thereby improving the efficiency of the heat dissipation of the simulated server. Setting the cooling chamber 12 at the top can utilize the principle of hot air rising, so that the hot air rises naturally and the cold air falls, forming effective heat convection, thereby improving the heat dissipation effect, so as to improve the authenticity and test effect of the simulated server test.

[0097] That is to say, arranging the cooling chamber 12 and the heating chamber 13 on the upper and lower sides of the test chamber 11 respectively helps to improve the accuracy of server testing, simulate the actual working environment, optimize the airflow organization, and enhance the heat dissipation effect of the simulated server.

[0098] In some embodiments, the sliding control assembly 40 includes a servo hydraulic cylinder 41 , both ends of which are rotatably connected to the inner wall of the test housing 20 and the sealing slider 30 , respectively. The servo hydraulic cylinder 41 is used to push the sealing slider 30 to slide in the inner cavity 21 .

[0099] On the basis that the sealing slider 30 is tightly fitted to the inner wall of the test shell 20 through the sealing rubber ring 31, the servo hydraulic cylinder 41 pushes the sealing slider 30 to move along the inner wall of the test shell 20, and the servo hydraulic cylinder 41 and the sealing slider 30 are symmetrically distributed about the central axis of the test shell 20.

[0100] Please also read Figure 5 A pair of servo hydraulic cylinders 41 are arranged on the side of a sealing slider 30 away from the sealing test chamber 22. When the pair of servo hydraulic cylinders 41 are synchronously extended, the sealing slider 30 slides inward to achieve the effect of reducing the volume of the sealing test chamber 22. When the pair of servo hydraulic cylinders 41 are synchronously retracted, the sealing slider 30 slides outward to achieve the effect of increasing the volume of the sealing test chamber 22.

[0101] In addition, a monitoring system can be set up to monitor the operation of the test device.

[0102] To this end, the server heat dissipation testing device also includes a temperature sensor 110, which is installed in different areas of the sealed test chamber 22. The temperature sensor 110 is used to detect the temperature of the circulating fluid in the sealed test chamber 22 to monitor the operation of the circulating fluid in the sealed test chamber in the testing device.

[0103] By using the temperature sensor 110 , the temperature change of the circulating fluid in different areas of the sealed test chamber 22 within a specified time after the test device starts running can be known, and the test result can be compared and verified with the expected result.

[0104] Please also read Fig. 9 The sliding control component 40 also includes a control module 42, which is communicatively connected to the temperature sensor 110, the servo hydraulic cylinder 41, the circulating pump 53, the liquid exchange valve 61 and the heating component 51. The control module 42 is used to receive the temperature data in the sealing test chamber 22 transmitted by the temperature sensor 110, and control the servo hydraulic cylinder 41, the circulating pump 53, the liquid exchange valve 61 and the heating component 51 to work according to the temperature data detected by the temperature sensor 110.

[0105] In some embodiments, a flow control valve can also be provided on the liquid supply pipe body 72 located on one side of the corresponding sealing test cavity 22. The flow control valve is used to control the flow of circulating liquid entering the sealing test cavity 22. In this way, the control module 42 can be used to communicate with the temperature sensor 110 in the corresponding sealing test cavity 22 and the flow control valve on the corresponding liquid supply pipe body 72. When the temperature sensor 110 transmits the detected temperature data in the corresponding sealing test cavity 22 (the simulated temperature data when the server is actually working) to the control module 42, the control module 42 is used to control the opening of the corresponding flow control valve according to the temperature data detected by the corresponding temperature sensor 110, thereby accurately controlling the flow of circulating liquid supplied from the circulating water tank 50 to the corresponding sealing test cavity 22.

[0106] That is to say, the embodiment of the present invention combines the setting of the heating component 51 and the flow control valve. When the circulating liquid continuously circulates in the sealed test chamber 22 in the test shell 20, the control module 42 is used to control the start of the heating elbow and the opening of the corresponding flow control valve according to the temperature data detected by the temperature sensor 110 in the sealed test chamber 22, so as to accurately control the circulating liquid with the target simulation temperature to flow into the corresponding sealed test chamber 22 at a specified flow rate, thereby realizing a true simulation of the server bearing a preset load during operation.

[0107] This setting can reduce test errors caused by temperature fluctuations by precisely controlling the simulated temperature and flow rate, providing a realistic simulation of the server bearing the preset load during operation, helping to improve test accuracy and efficiency while optimizing the server cooling system design.

[0108] In addition, in order to ensure the stability of the test cabinet 10 during testing, a plurality of tripods 120 are provided at the bottom of the test cabinet 10 , and the plurality of tripods 120 are symmetrically distributed about the central axis of the test cabinet 10 .

[0109] The following specifically describes the testing process of the server heat dissipation testing device provided by the embodiment of the present invention:

[0110] Before the test, thermal silicone oil is injected into the test cabinet 10, and circulating liquid is injected into the circulating water tank 50 and the balancing water tank 60 to complete the preparations before the formal test. Before the test, the temperature sensor 110 for the test is reasonably arranged in the device according to the test requirements to improve the accuracy of the test data.

[0111] During the test, the circulation pump 53 is first controlled to start, and the circulating liquid is delivered to the sealing test chamber 22 in the corresponding test housing 20 through the first connecting pipe 71 and the liquid supply pipe body 72, and the circulating liquid in the sealing test chamber 22 is returned to the circulating water tank 50 through the second connecting pipe 81 and the liquid return pipe body 82. While delivering the circulating liquid, the sealing slider 30 is controlled by the sliding control component 40 to move along the inner wall of the test housing 20, and the size of the sealing test chamber 22 inside the test housing 20 is adjusted so that the volume of the sealing test chamber 22 matches the volume of the simulated server, so as to achieve the test of the sealing test chamber 22. Simulation test of servers with the same volume; during the adjustment process, open the switch of the control liquid exchange valve 61 so that the water in the balancing water tank 60 can flow smoothly into the circulating water tank 50, so that the liquid level in the circulating water tank 50 is always higher than the height of the heating elbow, and the balance control of the circulating liquid amount in the circulating water tank 50 is completed to ensure the normal circulation of the circulating liquid during the test. When the circulating liquid is continuously circulating in the sealed test cavity 22 in the test shell 20, start the heating elbow to heat the circulating circulating liquid to the target simulation temperature, so as to realize the real simulation of the server bearing different loads during operation.

[0112] During the heating process, the test shell 20 conducts its own heat away through the thermal silicone oil in the test chamber 11, thereby realizing the heat dissipation simulation of the dummy load. At the same time, the test data can be recorded by observing the temperature change information transmitted by the temperature sensor 110. Finally, the cooling pump 100 is started, and the thermal silicone oil in the test chamber 11 is pumped into the cooler 90 through the suction pipe 101 to cool the thermal silicone oil. The cooled thermal silicone oil is discharged into the test chamber 11 again through the discharge pipe 91, thereby realizing the circulating cooling of the thermal silicone oil and ensuring the heat dissipation effect of the simulated load test.

[0113] In summary, the server heat dissipation testing device provided in the embodiment of the present invention realizes the simulation of servers of different sizes by setting a fixed test shell 20, a sealing slider 30 that can slide freely along the inner wall of the test shell 20, and a sliding control component 40 that controls the sealing slider 30 to slide along the inner wall of the test shell 20. In addition, while performing the simulation, it ensures that the sealed test cavity 22 is always in a sealed state, which simplifies the operating steps when simulating servers of different volumes, reduces the labor intensity of operators, and improves the efficiency of server simulation testing.

[0114] Moreover, the server heat dissipation test device provided in the embodiment of the present invention is also connected to the circulating water tank 50 through the arranged balancing water tank 60, so as to realize the arbitrary adjustment of the circulating liquid volume in the sealed test chamber 22 in the test shell 20 while avoiding affecting the liquid level in the circulating water tank 50. In this way, it can be ensured that the liquid level in the circulating water tank 50 is always higher than the height of the heating component 51 in the circulating water tank 50, thereby ensuring the safety of heating, and also realizing the complete isolation of the heating liquid in the circulating water tank 50 and the cooling liquid in the balancing water tank 60, thereby ensuring that the circulating liquid is completely not affected by the volume of the sealed test chamber 22 during circulation, thereby ensuring the accuracy of the test results and reducing the test errors.
