[0036] The present application discloses a test device for a liquid cooling system, which detects the leakage risk of a pipeline to be tested from multiple aspects to improve the accuracy of test results.

[0037] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0038] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0039] The liquid cooling system is a structure that realizes heat dissipation of the heat source by circulating the coolant through the pipeline system by a circulating pump and using the flowing coolant to take away the heat. With the wide application of the liquid cooling system and the increasing complexity of the application scenarios, for example, frequent high and low temperature changes, system vibrations, and flow rate fluctuations, etc., the leakage risk of the liquid cooling system has increased significantly.

[0040] In some embodiments, the leakage test method for the pipeline of the liquid cooling system only performs vibration or environmental aging tests on a single component. Since the liquid cooling system usually includes multiple pipelines connected by sealed connectors, this one-sided evaluation method cannot comprehensively identify the leakage risk of the liquid cooling system.

[0041] In order to test the leakage risk of the pipeline of the liquid cooling system to detect the service life and quality of the liquid cooling system. Based on this, a test device for the liquid cooling system is disclosed in the present application, which integrates the pressure tightness test of the liquid cooling system, the vibration tolerance test of the liquid cooling system, and the simulation test of the external environmental temperature change. By reproducing the actual working conditions of the liquid cooling system and simulating different working conditions of the liquid cooling system, it aims to improve the detection accuracy of the leakage risk, comprehensively evaluate the performance of the liquid cooling system, and solve the compatibility problem between the vibration table and the environmental temperature chamber.

[0042] Combined Figure 1 As shown, the test device for the liquid cooling system in the present application includes: a coolant box 1, a circulation pipeline 2, a pipeline to be tested 100, and a vibration assembly.

[0043] Among them, the coolant box 1 includes an inlet pipeline and an outlet pipeline. For the inlet pipeline and the outlet pipeline, they can be arranged at any position of the coolant box 1. Optionally, the height of the inlet pipeline is higher than the height of the outlet pipeline. Exemplarily, Figure 1Above the side plate of the coolant tank 1 is the inlet pipeline, and below is the outlet pipeline. The inlet pipeline and the outlet pipeline in this application can be set according to different needs and are both within the protection scope.

[0044] The circulation pipeline 2 is connected to the pipeline to be tested 100 and is also connected to the inlet pipeline and the outlet pipeline of the coolant tank 1, thus forming a closed-loop channel. The size and layout of the circulation pipeline 2 can be set according to different needs and are not specifically limited here. The pipeline to be tested 100 can be connected to the middle position of the circulation pipeline 2 to ensure the installation of the equipment for testing the pipeline to be tested 100, thereby facilitating the testing operation of the pipeline to be tested 100. The connection method between the circulation pipeline 2 and the pipeline to be tested 100 includes but is not limited to connection through a quick connector.

[0045] The vibration assembly drives the pipeline to be tested 100 to vibrate, and the vibration direction of the vibration assembly includes but is not limited to Figure 1 the up and down direction in Figure 1 or the left and right direction in. It can be understood that the vibration direction is the radial direction of the pipeline to be tested 100 to test the stability of the connection between the pipeline to be tested 100 and the circulation pipeline 2, and whether there will be leakage at the connection between the pipeline to be tested 100 and the circulation pipeline 2 and at the connections in the pipeline to be tested 100 during the vibration process.

[0046] It should be emphasized that the pipeline to be tested 100 referred to in this application is: two or more pipelines connected to each other through a connection structure, and the pipeline to be tested 100 is exactly the same as the pipelines other than the circulation pipeline in the actual product.

[0047] Furthermore, a circulation pump 8 can also be set on the circulation pipeline of the liquid cooling and heat dissipation system test device. The circulation pump 8 is used to provide power for the flow of the liquid in the circulation channel formed by the coolant tank 1, the circulation pipeline 2, and the pipeline to be tested 100. By changing the rotation speed of the circulation pump 8, the flow rate of the liquid in the pipeline to be tested 100 can be changed, and through the pressure regulating device, the pressure change of the liquid in the circulation channel can be realized.

[0048] It can be understood that the vibration direction can be the radial direction of the pipeline to be tested 100 or a direction intersecting with the radial direction of the pipeline to be tested 100.

[0049] During the test of the pipeline to be tested 100, by changing the pressure of the liquid provided by the coolant tank 1 to the circulation pipeline 2, the sealing test of the pipeline to be tested 100 under different pressures can be realized. By changing the vibration frequency of the vibration assembly, the sealing performance test of the pipeline to be tested 100 at different vibration frequencies can be realized.

[0050] The test device for the liquid cooling and heat dissipation system disclosed in this application forms a circulation path by connecting the pipeline to be tested 100 with the circulation pipeline 2 and the coolant tank 1, so as to simulate the seal test of the pipeline to be tested 100 under different pressure conditions; the pipeline to be tested 100 is connected to the vibration assembly to simulate the seal test of the pipeline to be tested 100 under different vibration frequency conditions. The test device for the liquid cooling and heat dissipation system in this application integrates the pressure seal test of the pipeline to be tested 100 and the vibration tolerance test of the liquid cooling and heat dissipation system, so as to simulate different working conditions of the liquid cooling and heat dissipation system, comprehensively evaluate the performance of the liquid cooling system, and improve the accuracy of the test results of the pipeline to be tested 100.

[0051] In the above embodiments, it is disclosed that the vibration assembly is used to vibrate the pipeline to be tested 100 to detect the seal of the pipeline to be tested 100 at different vibration frequencies.

[0052] Based on the above technical solutions, the test device for the liquid cooling and heat dissipation system in some embodiments further includes: a workpiece fixing tooling 5. By using the workpiece fixing tooling 5 to support the pipeline to be tested 100, it can be understood that the pipeline to be tested 100 can be fixed on the workpiece fixing tooling 5. The connection method between the pipeline to be tested 100 and the workpiece fixing tooling 5 includes but is not limited to limit connection or clamping, so as to avoid problems such as deformation of the pipeline to be tested 100 under the action of gravity.

[0053] The above vibration assembly is connected to the workpiece fixing tooling 5, and the vibration assembly drives the workpiece fixing tooling 5 to vibrate.

[0054] Exemplarily, the workpiece fixing tooling 5 includes a support plate 52 and a limit post 51. Among them, the limit post 51 is fixed on the support plate 52, and the limit post 51 and the support plate 52 include but are not limited to being integrally formed. During the process of using the workpiece fixing tooling 5 to support the pipeline to be tested 100, the pipeline to be tested 100 is placed on the support plate 52, and the limit post 51 is used to limit the pipeline to be tested 100 to ensure that the pipeline to be tested 100 is stable and does not shift during vibration, that is, the fixing of the pipeline to be tested 100 on the workpiece fixing tooling 5 is realized, and the accuracy of the test results is improved.

[0055] The support plate 52 is connected to the driving assembly, and the driving assembly is used to drive the support plate 52 to vibrate, so that the pipeline to be tested 100 fixed on the support plate 52 is vibrated.

[0056] The above discloses that in the test device for the liquid cooling and heat dissipation system, the vibration assembly is used to drive the pipeline to be tested 100 on the workpiece fixing tooling 5 to vibrate, so as to realize the seal detection of the pipeline to be tested 100 at different vibration frequencies.

[0057] Based on the above, in some embodiments, the test device of the liquid cooling and heat dissipation system further includes an environmental temperature chamber 4, which is used to simulate the high and low temperature changes of the external environment, so as to realize the sealing performance test of the pipeline to be tested 100 at different temperatures.

[0058] Exemplarily, Figure 1 the pipeline to be tested 100 in [] is arranged inside the environmental temperature chamber 4. Specifically, the pipeline to be tested 100 is connected to the wall of the environmental temperature chamber 4 through an elastic sealing ring and extends out of the environmental temperature chamber 4 to communicate with the circulation pipeline 2; it is also possible that the circulation pipeline 2 is connected to the wall of the environmental temperature chamber 4 through an elastic sealing ring and extends into the environmental temperature chamber 4 to communicate with the pipeline to be tested 100.

[0059] It should be noted that the environmental temperature chamber 4 is a sealed box, and by changing the temperature inside the environmental temperature chamber 4, the high and low temperature changes of the external environment of the circulation pipeline 2 are simulated. The temperature inside the environmental temperature chamber 4 is adjustable. Exemplarily, the temperature inside the environmental temperature chamber 4 can cycle between -50°C and 150°C.

[0060] During the test of the pipeline to be tested 100, by changing the temperature inside the environmental temperature chamber 4, the change of the external environment temperature of the pipeline to be tested 100 is simulated, so as to realize the sealing performance test of the pipeline to be tested 100 at different temperatures.

[0061] In some embodiments, in the above test device of the liquid cooling and heat dissipation system, a pressure regulating device 7 is further included, which is connected to the circulation pipeline 2. By setting the pressure regulating device 7, the pressure of the liquid in the circulation channel can be directly changed by mechanical equipment, so as to realize the sealing performance test of the pipeline to be tested 100 under different pressure conditions.

[0062] Exemplarily, the pressure regulating device 7 can be a pressure regulating valve, which is connected in series to the circulation pipeline 2 and can change the pressure on the circulation pipeline 2. By changing the flow area at the regulating valve, the pressure of the liquid in the circulation pipeline is changed.

[0063] Figure 1 The test device of the liquid cooling and heat dissipation system in [] further includes a differential pressure sensor 3, which is used to detect the pressure difference between the inlet end and the outlet end of the pipeline to be tested 100. The probe of the differential pressure sensor 3 can extend into the pipeline to be tested 100. By detecting the pressure difference between the inlet end and the outlet end of the pipeline to be tested 100 through the differential pressure sensor 3, if the pipeline to be tested 100 leaks, the pressure difference will increase.

[0064] Optionally, the differential pressure sensor 3 can also detect the pressure difference between the inlet end and the outlet end of the circulation pipeline 2 to indirectly obtain whether the pipeline to be tested 100 leaks. If the pipeline to be tested 100 leaks, the pressure difference will increase.

[0065] Combined withFigures 1 to 7 In the illustrated embodiment, the workpiece fixing fixture 5 is disposed inside the environmental incubator 4 and is specially designed to ensure that the pipeline 100 under test does not shift during vibration.

[0066] Exemplarily, the driving assembly extends into the environmental incubator 4 and is in transmission connection with the support plate 52 of the workpiece fixing fixture 5. The driving assembly drives the workpiece fixing fixture 5 to vibrate relative to the environmental incubator 4, that is, the driving assembly drives the workpiece fixing fixture 5 to vibrate while the environmental incubator 4 does not vibrate.

[0067] For the connection manner of the driving assembly to the environmental incubator 4 and the connection manner of the driving assembly to the support plate 52, reference can be made to the following description.

[0068] See Figure 2 As shown, the environmental incubator 4 includes an upper shell 41 and a lower shell 42. The upper shell 41 and the lower shell 42 are hermetically connected, and the workpiece fixing fixture 5 is hermetically sealed inside the environmental incubator 4. Exemplarily, one end of the pipeline 100 under test extends out of the environmental incubator 4 from the top of the upper shell 41, and the other end extends out of the environmental incubator 4 from the side of the upper shell 41. The differential pressure sensor 3 detects the pressure inside the pipeline 100 under test through the top of the upper shell 41.

[0069] In an alternative embodiment, the upper shell 41 and the lower shell 42 are detachably connected to facilitate the taking and placing of the pipeline 100 under test inside. The connection manner of the upper shell 41 and the lower shell 42 includes but is not limited to snap connection, connection by threaded parts, or bonding.

[0070] It should be noted that the shape, size, and material of the environmental incubator 4 in this article can be set according to different needs and are all within the protection scope. Figure 2 Only one structure of the environmental incubator 4 is exemplified herein, and environmental incubators 4 with other structures are also within the protection scope.

[0071] The vibration assembly in this application includes: a driving motor 9 and a sliding sleeve 92.

[0072] Among them, the driving motor 9 is located outside the environmental incubator 4, and the driving shaft 91 of the driving motor 9 penetrates through the lower shell 42 of the environmental incubator 4 and is connected to the workpiece fixing fixture 5. Exemplarily, the lower shell 42 has a through hole, and the driving shaft 91 extends into the interior of the environmental incubator 4 through the through hole and is in transmission connection with the support plate 52, for example, fixedly connected. During the operation of the driving motor 9, the driving shaft 91 can move along the axial direction of the through hole, and the driving motor 9 provides vibration kinetic energy to simulate the vibration situation in actual operation. The driving shaft 91 of the driving motor 9 is connected to the support plate 52 of the workpiece fixing fixture 5 inside the environmental incubator 4, and the vibration kinetic energy directly acts on the workpiece fixing fixture 5.

[0073] It should be noted that the drive shaft 91 of the drive motor 9 in this article can be the shaft of the drive motor 9 itself or a connecting rod connected to the shaft of the drive motor 9 itself.

[0074] In an alternative embodiment, the drive motor 9 is a servo motor.

[0075] The perfect integration of the workpiece fixing tooling 5 and the environmental incubator 4 in this application: The workpiece fixing tooling 5 is arranged at the bottom of the environmental incubator 4, and the necessary vibration power is provided by an accurate servo motor. The power of the servo motor does not act on the environmental incubator 4, but directly acts on the workpiece fixing tooling 5 through the drive shaft 91 or a connecting rod connected to the drive shaft 91, reducing the load of the servo motor. In the case of a servo motor with the same power, this device can carry a heavier pipeline 100 to be tested, expanding the weight boundary of the vibration test; in addition, the energy required to drive the vibration of the environmental incubator 4 is reduced, thereby reducing energy waste.

[0076] A frustum 421 is provided on the bottom surface of the lower shell 42. The frustum 421 extends towards the inside of the environmental incubator 4, and the drive shaft 91 passes through the frustum 421. By providing the frustum 421, the contact area between the environmental incubator 4 and the drive shaft 91 can be increased, facilitating the guiding of the movement of the drive shaft 91 and preventing the drive shaft 91 from shifting during vibration. The size of the frustum 421 can be set according to different needs and is within the protection range.

[0077] Combined Figure 6 and Figure 7 As shown, a sliding sleeve 92 is provided between the frustum 421 and the drive shaft 91 in this application. By providing the sliding sleeve 92, while achieving the sealing between the drive shaft 91 and the inner wall of the frustum 421, the friction generated during the relative movement between the drive shaft 91 and the inner wall of the frustum 421 can also be reduced.

[0078] In some embodiments, the sliding sleeve 92 is a graphite sealing ring.

[0079] The connection part between the environmental incubator 4 and the drive shaft 91 is sealed with a graphite sealing ring, which can not only play a lubricating role but also have a good heat preservation effect, while avoiding damage to the servo motor by the environmental incubator 4; in addition, during the movement of the drive shaft 91 relative to the frustum 421, due to the small friction of the graphite sealing ring, the wear of the environmental incubator 4 on the drive shaft 91 can be reduced.

[0080] In an alternative embodiment, the graphite sealing ring is located at the middle position in the axial direction of the frustum 421, and a groove for accommodating the graphite sealing ring is provided on the inner wall of the frustum 421. The graphite sealing ring is installed in the groove to limit the graphite sealing ring in the axial direction of the drive shaft 91, preventing the graphite sealing ring from moving with the drive shaft 91.

[0081] In some embodiments, the graphite sealing ring can also be cooperatively connected with the drive shaft 91 and can move relative to the frustum 421 along with the drive shaft 91. During the movement of the graphite sealing ring, the frictional force between the graphite sealing ring and the inner wall of the frustum 421 is small, thereby reducing the wear of the inner wall of the frustum 421 on the drive shaft 91.

[0082] Combined Figure 1 with Figure 5 As shown, a liquid leakage hole 422 is provided at the bottom surface of the lower shell 42 of the environmental incubator 4 disclosed in the present application, and a leakage judgment box 6 is connected to the liquid leakage hole 422.

[0083] During the test process of the pipeline 100 to be tested, the pipeline 100 to be tested may leak, and the leaked liquid will collect on the bottom surface of the lower shell 42 of the environmental incubator 4. The leaked liquid can be discharged from the environmental incubator 4 through the liquid leakage hole 422, and the leakage judgment box 6 collects the liquid at the liquid leakage hole 422, thereby clarifying the leakage amount of the pipeline 100 to be tested during the test process, providing an intuitive and reliable basis for leakage judgment, and the sealing performance of the pipeline 100 to be tested can be judged according to the leakage amount. If the leakage amount is more under the same conditions, it means that the sealing performance of the pipeline 100 to be tested is worse.

[0084] The leakage judgment box 6 is located outside the environmental incubator 4 and is connected to the liquid leakage hole 422 of the environmental incubator 4 through a pipeline. The leakage judgment box 6 is responsible for collecting and analyzing the generated leakage liquid and providing timely and accurate leakage feedback to the test personnel.

[0085] Exemplarily, the lower shell 42 of the environmental incubator 4 is funnel-shaped to guide and collect the liquid leaked from the pipeline 100 to be tested and introduce it into the leakage judgment box 6 for detection, clarify the leakage amount, and provide an intuitive and reliable basis for leakage judgment.

[0086] In order to make the leaked liquid flow to the leakage judgment box 6 faster and thus collect the leaked liquid more conveniently, the liquid leakage hole 422 is provided at the lowest point of the lower shell 42 of the environmental incubator 4.

[0087] The test device for the liquid cooling and heat dissipation system disclosed in the present application can not only simulate a complex actual working environment, but also comprehensively evaluate the sealing performance of the liquid cooling and heat dissipation system, providing strong support for the design and quality evaluation of the liquid cooling and heat dissipation system. The test device in the present application is easy to operate and reusable, greatly improving the test efficiency and accuracy. The test device solves the problem in the prior art that it is difficult to detect the leakage risk of the liquid cooling and heat dissipation system and helps to promote the safe and stable development of the energy storage field. It is expected that the device will be widely used in the research and development, production and quality control of various energy storage devices and liquid cooling and heat dissipation systems.

[0088] In the present specification, the various embodiments are described in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts among the various embodiments can be referred to each other.

[0089] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but rather will be accorded the widest scope consistent with the principles and novel features disclosed herein.
