Description

Technical Field

[0001] This application relates to the field of testing technology, and in particular to a testing device for heat exchanger fittings and a heat exchanger device. Background Technology

[0002] With continuous technological advancements, heat exchange equipment is widely used in many applications, especially in fields requiring efficient heat dissipation, such as electric vehicles, power electronic equipment, data centers, and high-performance computers. To ensure the long-term reliability of heat exchange equipment, particularly under high-temperature and high-pressure conditions, rigorous testing and evaluation are necessary.

[0003] Heat exchange equipment includes heat exchanger fittings. These fittings typically include cold plates, pipe fitting assemblies, and heat exchangers, and each fitting must maintain stable performance under high temperature and high pressure conditions. The reliability of these heat exchanger fittings under long-term high temperature and high pressure is tested, and their long-term reliability is evaluated.

[0004] However, existing testing devices for heat exchanger fittings cannot control system pressure or simulate the pressure exerted on the pipes during flushing. Alternatively, while the pressure, flow rate, and temperature may be adjustable, the methods for adjusting pressure and flow rate are cumbersome and require numerous components. Utility Model Content

The testing device for heat exchanger pipe fittings provided in this application has a simple structure, requires fewer components, and includes storage and detection components, making temperature, flow rate, and pressure controllable.

[0006] The first aspect of this application provides a testing device for heat exchanger pipe fittings, used to test the corrosion resistance of the pipe fitting under test, comprising:

[0007] Storage components for storing corrosive fluids;

[0008] Detection components;

[0009] A piping assembly, including a main pipeline and at least two test pipelines, wherein the at least two test pipelines are arranged in parallel and are both connected to the main pipeline;

[0010] Both the detection components and the storage components are connected to the main pipeline.

[0011] The testing device for heat exchanger pipe fittings provided in the first aspect of this application is used to test the corrosion resistance of the pipe fitting under test. The testing device includes a storage unit, a detection component, and a piping assembly. The storage unit is used to store corrosive fluid. The piping assembly includes a main pipeline and at least two test pipelines, which are connected in parallel and both are connected to the main pipeline. The detection component and the storage unit are both connected to the main pipeline. Thus, the testing device for heat exchanger pipe fittings provided in this application has a simple structure, requires fewer components, and the inclusion of a storage unit and a detection component allows for controllable temperature, flow rate, and pressure.

[0012] In one possible implementation, the main pipeline includes a first pipe section and a second pipe section, one end of the first pipe section is connected to the liquid outlet of the storage device, and the other end of the first pipe section is connected to the liquid inlet of each test pipeline.

[0013] One end of the second pipe section is connected to the liquid outlet of each test pipe, and the other end of the second pipe section is connected to the liquid inlet of the storage device.

[0014] In this way, the main pipeline and the test pipeline are connected to form a complete fluid pipeline, which facilitates the smooth flow of fluid and enables the testing of the pipe fitting under test.

[0015] In one possible implementation, it also includes: a quick-connect fitting;

[0016] The quick-connector includes a first connector and a second connector. The first connector is connected to the test pipeline, and the second connector is detachably connected to the first connector. The second connector is connected to the pipe to be tested through the main pipeline.

[0017] In this way, by setting up quick-connect fittings, the quick-connect fittings can be detachably connected to the piping assembly, which facilitates the quick replacement of the pipe fittings under test.

[0018] In one possible implementation, the detection components include: a pressure sensor, a flow meter, and a temperature control device;

[0019] Both the pressure sensor and the flow meter are located in the second pipe section, with the pressure sensor positioned on the side of the flow meter closest to the test pipe.

[0020] The temperature control device is located in the storage unit.

[0021] In this way, by setting up pressure sensors, flow meters, and temperature control devices, the pressure, flow rate, and temperature of the pipe fitting under test can be detected and controlled respectively.

[0022] In one possible implementation, it further includes: a control element located on the second pipe section;

[0023] The inlet end of the control unit is connected to the outlet end of the pressure sensor, and the outlet end of the control unit is connected to the flow meter.

[0024] In this way, by setting up control components, the flow of fluid can be controlled quickly and effectively, and by adjusting the control components, the fluid flow rate can be controlled.

[0025] In one possible implementation, it further includes: a drive member located on the first pipe segment;

[0026] The inlet end of the drive unit is connected to the outlet end of the storage unit, and the outlet end of the drive unit is connected to the inlet end of each test pipeline.

[0027] In this way, the flow rate of the testing device can be controlled by setting the driving component and adjusting its rotation speed.

[0028] In one possible implementation, the quick-connect fitting is also located on the first pipe section;

[0029] The quick-connector is located between the liquid outlet of the storage unit and the liquid inlet of the drive unit, and between the liquid outlet of the drive unit and the liquid inlet of each test line.

[0030] In this way, by setting quick-connect fittings at both ends of the drive component, it can be quickly replaced when the drive component is damaged. Due to the self-sealing property of the quick-connect fittings in the disconnected state, the drive component can be replaced without draining fluid, thus avoiding leakage.

[0031] In one possible implementation, it further includes: a control module;

[0032] The control module is electrically connected to the pressure sensor, flow meter, and temperature control device, respectively.

[0033] The control module is connected to the drive unit via a plug-in terminal.

[0034] In this way, the control module acquires pressure data of the pipe under test through a pressure sensor, acquires flow data of the pipe under test through a flow meter, and controls the temperature of the pipe under test through a temperature control device.

[0036] The piping assembly also includes an exhaust pipe, one branch of the first pipe section is connected to the liquid inlet of each test pipe, and the other branch of the first pipe section is connected to the exhaust pipe.

[0037] The exhaust valve is located in the exhaust pipe.

[0038] In this way, by setting an exhaust valve, the pressure of the entire testing device can be prevented from becoming too high.

[0039] A second aspect of this application provides a heat exchange device, including a testing apparatus for the aforementioned heat exchange tubes.

[0040] It should be understood that the second aspect of this application corresponds to the technical solution of the first aspect of this application, and the beneficial effects achieved by each aspect and the corresponding feasible implementation are similar, and will not be repeated here.

[0054] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0055] This application provides a heat exchange device (not shown in the figure) that can be used to transfer heat between two or more fluids. The heat exchange device may include a testing apparatus 100 for heat exchanger fittings. It is understood that the testing apparatus 100 is used to test the fitting 900 under test to evaluate its corrosion resistance, wear resistance, and fatigue resistance during long-term use.

[0056] It is understood that the structures illustrated in the embodiments of this application do not constitute a specific limitation on the heat exchange equipment. In other embodiments of this application, the heat exchange equipment may include more or fewer components, or combine some components, or split some components, or have different component arrangements.

[0057] In related technologies, testing devices for heat exchanger fittings often fail to control system pressure, making it impossible to simulate the pressure exerted on the pipes during flushing. Alternatively, while the pressure, flow rate, and temperature in the testing devices for heat exchanger fittings may be adjustable, the methods for adjusting pressure and flow rate are cumbersome and require numerous components.

[0058] To simplify the architecture of the testing device for heat exchanger tubes and ensure controllability of temperature, flow rate, and pressure within the device, this application provides a testing device 100 for heat exchanger tubes, addressing the aforementioned technical problems. The testing device 100 includes a storage unit 200, a detection component 300, and a piping assembly 400. The storage unit 200 stores corrosive fluid. The piping assembly 400 includes a main pipeline 410 and at least two test pipelines 420, which are connected in parallel and both communicate with the main pipeline 410. The detection component 300 and the storage unit 200 are both connected to the main pipeline 410. Thus, the testing device 100 for heat exchanger tubes provided in this application has a simple architecture, requires fewer components, and the inclusion of the storage unit 200 and the detection component 300 ensures controllability of temperature, flow rate, and pressure.

[0059] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0060] The specific structure of a testing device 100 for heat exchanger tubes provided in this application embodiment will be described below with reference to the accompanying drawings.

[0061] refer to Figure 1 This application provides a testing apparatus 100 for heat exchanger pipe fittings in a first aspect. It is understood that the testing apparatus 100 can be used to test the corrosion resistance of a pipe fitting 900 under test. The testing apparatus 100 may include a storage unit 200, a detection component 300, and a piping assembly 400. It is understood that the storage unit 200 can be used to store corrosive fluids. In one possible implementation, such as... Figure 1 As shown, the storage device 200 may have an internal cavity 210 in which fluid may be stored. The embodiments described in this application are not intended to be limiting.

[0062] Continue to refer to Figure 1 Based on the above embodiments, the piping assembly 400 may include a main pipeline 410 and at least two test pipelines 420. In one possible implementation, the number of test pipelines 420 may be at least two; however, this application embodiment does not limit the number of test pipelines 420. In this application embodiment, at least two test pipelines 420 are arranged in parallel, and each test pipeline 420 is connected to the main pipeline 410. It is understood that the pipe under test 900 can be connected to the test pipeline 420 to achieve performance testing of the pipe under test 900.

[0063] It is also understandable that multiple test tubes 900 are connected in parallel through multiple test lines 420, so that the flow rate and pressure flowing through each test tube 900 are approximately the same. Based on the parallel characteristics of the test lines 420, the test tubes 900 in the test lines 420 can be controlled with fewer components, reducing the number of required components while ensuring test performance. Of course, in other embodiments, multiple test tubes 900 can also be connected in series through test lines 420, which will not be elaborated upon in this application.

[0064] Continue to refer to Figure 1Based on the above embodiments, both the detection component 300 and the storage component 200 can be connected to the main pipeline 410. In this way, by setting up the detection component 300 and the storage component 200, the test pipe 900 in the test pipeline 420 can be detected, so that the temperature, flow rate and pressure of the pipe 900 flowing through it can be controlled, and the device has a simple structure and is easy to operate.

[0065] Continue to refer to Figure 1 Based on the above embodiments, the main pipeline 410 may further include a first pipe section 411 and a second pipe section 412. One end of the first pipe section 411 may be connected to the liquid outlet of the storage device 200, and the other end of the first pipe section 411 may be connected to the liquid inlet of each test pipeline 420.

[0066] In addition, one end of the second pipe section 412 can be connected to the liquid outlet of each test pipe 420, and the other end of the second pipe section 412 can be connected to the liquid inlet of the storage device 200.

[0067] In this way, the main pipeline 410 and the test pipeline 420 are connected to form a complete fluid pipeline, which facilitates the smooth flow of fluid and realizes the testing function of the pipe fitting 900 under test.

[0068] Continue to refer to Figure 1 Based on the above embodiments, the testing device 100 for heat exchanger fittings may further include a quick-connect fitting 500. The quick-connect fitting 500 may further include a first fitting 510 and a second fitting 520. In one possible implementation, the first fitting 510 may be connected to the test pipeline 420, while the second fitting 520 may be connected to the fitting under test 900 via the main pipeline 410. Alternatively, the first fitting 510 and the second fitting 520 may be interchanged; this embodiment does not impose limitations here. It is understood that the second fitting 520 is detachably connected to the first fitting 510, thereby facilitating the quick replacement of the fitting under test 900.

[0069] In this embodiment, each test tube 900 can be connected to quick-connect fittings 500 at both ends to facilitate the installation and removal of the test tube 900.

[0070] Based on the above embodiments, the quick-connect fitting 500 can be, exemplarily, a hand-operated quick-connect fitting. It should be noted that the hand-operated quick-connect fitting has the characteristic of opening the flow channel when inserted and automatically sealing when disconnected. Specifically, when the first fitting 510 and the second fitting 520 are inserted and engaged, the flow channel of the quick-connect fitting 500 is in an open state, facilitating fluid flow within the quick-connect fitting 500. When the first fitting 510 and the second fitting 520 are disconnected, the quick-connect fitting 500 can automatically seal to prevent fluid leakage.

[0071] Continue to refer to Figure 1 Based on the above embodiments, the detection component 300 may include a pressure sensor 310, a flow meter 320, and a temperature control device 330. Both the pressure sensor 310 and the flow meter 320 can be disposed in the second pipe section 412, with the pressure sensor 310 located on the side of the flow meter 320 closer to the test pipe 420. It is understood that the pressure sensor 310 can be used to detect the pressure of the pipe fitting 900 under test, and the flow meter 320 can be used to detect the flow rate of the pipe fitting 900 under test.

[0072] Continue to refer to Figure 1 Based on the above embodiments, the temperature control device 330 can be disposed in the storage unit 200. It is understood that the temperature control device 330 is capable of regulating the temperature of the fluid in the internal cavity 210 of the storage unit 200. In this way, the fluid flows in the piping assembly 400, ensuring that the temperature of the tested pipe fitting 900 is the same as the temperature of the fluid in the internal cavity 210 of the storage unit 200.

[0073] Continue to refer to Figure 1 Based on the above embodiments, the testing device for the heat exchange component may further include a control element 600. The control element 600 may also be located on the second pipe section 412. In one possible implementation, the control element 600 may be located between the pressure sensor 310 and the flow meter 320. The inlet end of the control element 600 may be connected to the outlet end of the pressure sensor 310, while the outlet end of the control element 600 may be connected to the flow meter 320.

[0074] In one possible implementation, for example, the control element 600 may be a ball valve. It is understood that the control element 600 is capable of quickly and effectively controlling the flow of fluid, thereby controlling the magnitude of the fluid flow rate by adjusting the control element 600.

[0075] Continue to refer to Figure 1 Based on the above embodiments, the testing device for the heat exchange component may further include a drive element 700. The drive element 700 may be located on the first pipe section 411. In one possible implementation, the liquid inlet of the drive element 700 may be connected to the liquid outlet of the storage unit 200, while the liquid outlet of the drive element 700 may be connected to the liquid inlet of each test pipe 420.

[0076] In one possible implementation, exemplarily, the drive element 700 can be a pump body. It is understood that the flow rate of the testing device is controlled by adjusting the rotational speed of the drive element 700. Alternatively, in other embodiments, the drive element 700 can also be a pressure regulating valve; this application is not limiting in its embodiments.

[0077] Continue to refer to Figure 1 Based on the above embodiments, the quick-connect connector 500 can also be located on the first pipe section 411. Specifically, the quick-connect connector 500 can be located between the liquid outlet end of the storage component 200 and the liquid inlet end of the drive component 700, and the quick-connect connector 500 can also be located between the liquid outlet end of the drive component 700 and the liquid inlet end of each test pipe 420.

[0078] It is understood that, in this embodiment, the driving component 700 may have quick-connect connectors 500 at both ends. It is also understood that the driving component 700 is relatively easy to damage in actual working conditions. Therefore, by providing quick-connect connectors 500 at both ends of the driving component 700, quick installation and removal of the driving component 700 can be achieved. When the driving component 700 is damaged, it can be quickly replaced. Furthermore, compared to the driving component 700 in related technologies, the way the driving component 700 and quick-connect connector 500 are combined in this embodiment, due to the self-sealing characteristic of the quick-connect connector 500 in the disconnected state, eliminates the need for drainage during the replacement of the driving component 700, thus avoiding leakage.

[0079] Continue to refer to Figure 1 Based on the above embodiments, the testing device for the heat exchange component may further include a control module 800. The control module 800 can be electrically connected to the pressure sensor 310, the flow meter 320, and the temperature control device 330, respectively. Thus, the control module 800 can acquire pressure data of the pipe under test 900 through the pressure sensor 310, acquire flow data of the pipe under test 900 through the flow meter 320, and control the temperature of the pipe under test 900 through the temperature control device 330.

[0080] Additionally, the control module 800 can also be connected to the drive unit 700 via a mating terminal 710. It is understood that one end of the drive unit 700 can also be provided with a mating terminal 710, allowing the control module 800 to be electrically connected to the drive unit 700 via the mating terminal 710. This enables the control module 800 to adjust the rotational speed of the drive unit 700 to achieve different fluid flow rates.

[0081] Continue to refer to Figure 1Based on the above embodiments, the testing device for the heat exchange component may further include an exhaust valve 431. In one possible implementation, the piping assembly 400 may further include an exhaust pipe 430. In this embodiment, on the first pipe section 411 of the main pipe 410, the fluid may have two branch pipes after flowing through the outlet end of the drive member 700. One branch of the first pipe section 411 may be connected to the inlet end of each test pipe 420, and the other branch of the first pipe section 411 may be connected to the exhaust pipe 430. It is understood that the exhaust valve 431 is located in the exhaust pipe 430. Thus, by setting the exhaust valve 431, excessive pressure in the entire testing device can be avoided.

[0082] In this embodiment, the drive unit 700 is disposed on the first pipe section 411, and the pressure sensor 310, the control unit 600, and the flow meter 320 are all disposed on the second pipe section 412. It is understood that the pressure at the outlet of the drive unit 700 is relatively high, and the pressure decreases as the fluid flows through the pipe assembly 400. Figure 1 As shown, the pressure sensor 310, control unit 600, flow meter 320 and storage unit 200 are subjected to relatively low pressure, which can improve the service life of each component.

[0083] Of course, in another embodiment, the pressure sensor 310 and the flow meter 320 may also be disposed on the first pipe section 411. This application does not limit the scope of the embodiments described herein.

[0084] Continue to refer to Figure 1 Based on the above embodiments, in one possible implementation, the number of the test fitting 900 and the test line 420 is the same. This application embodiment does not limit the specific number of the test fitting 900 and the test line 420. In this application embodiment, three test fittings 900 are used as an example.

[0085] For example, the pipe under test 900 can be three water-cooled plates, and each water-cooled plate is connected to the test pipeline 420. In this embodiment of the application, the long-term erosion resistance reliability of the pipe under test 900 is measured at a working fluid temperature of 90°C, a flow rate of 1.5 LPM, and an outlet pressure of 400 kPa.

[0086] First, connect both ends of all the pipe fittings 900 to one of the first connector 510 and the second connector 520 in the quick-connect connectors 500, and connect them to the other connector in the first connector 510 and the second connector 520. The pipe fittings 900 are then installed in parallel on the test pipeline 420.

[0087] The temperature control device 330 is controlled by the control module 800, and the fluid in the storage unit 200 is heated to the set temperature of 90°C.

[0088] The speed of the drive component 700 is adjusted by the control module 800, and the opening ratio of the control component 600 is manually adjusted so that the flow rate collected by the flow meter 320 reaches 4.5 LPM and the pressure is about 400 kPa.

[0089] After adjusting the parameters of the detection component 300 in the testing device, it is powered on and operated under these parameters for a long period of time, or until the test pipe 900 in the test pipeline 420 leaks, and the long-term reliability data of the test pipe 900 is obtained.

[0090] Understandably, due to the high temperature during the test, if the drive unit 700 is damaged during the test, the fixture should be powered off, the quick-connect plugs and the mating terminals 710 at both ends of the drive unit 700 should be unplugged, and the fasteners on the drive unit 700 should be unscrewed. After replacing the drive unit 700, the test can continue.
