Technical Field
[0001] This utility model relates to the field of aging test technology, and in particular to a water circuit temperature control mechanism and an integrated water circuit temperature control mechanism. Background Technology
[0002] With the development of science and technology, people have increasingly higher requirements for the quality of electronic products. To improve product reliability and lifespan, aging tests are required before products leave the factory. Aging tests typically include common methods such as thermal aging tests, damp heat aging tests, and mechanical aging tests. Water circuit temperature control testing is a special type of thermal aging test that uses circulating water to control the product's temperature to simulate the thermal pressure under actual working conditions. Water circuit temperature control testing uses a water circuit temperature control structure to control and maintain the water temperature during the test. The water circuit temperature control structure generally consists of a water tank, a circulating pump, valves, and temperature sensors.
[0003] In order to control the existing outlet water temperature of the product, water circuit temperature control tests usually only set a temperature sensor at the inlet end. However, the above setting method may result in the inability to monitor the actual temperature distribution in the entire system, the inability to detect the heat dissipation effect of the product, and affect the accuracy of the test results. Utility Model Content
[0004] The main purpose of this utility model is to propose a water circuit temperature control mechanism and an integrated water circuit temperature control mechanism, which aims to solve the technical problem of inaccurate monitoring in existing water circuit temperature control structures.
[0005] To achieve the above objectives, this utility model proposes a water circuit temperature control mechanism for use in aging test products. The water circuit temperature control mechanism includes a water tank having an outlet and an inlet. In one embodiment, the water circuit temperature control mechanism includes:
[0006] A water inlet assembly, comprising a water inlet pipe and an electromagnetic proportional valve, wherein the electromagnetic proportional valve connects the water outlet and the water inlet pipe, and one end of the water inlet pipe is connected to the product;
[0007] A water return assembly, comprising a water return pipe, the two ends of which are respectively connected to the water return port and the product;
[0008] A water flow temperature sensor, comprising a first water flow temperature sensor and a second water flow temperature sensor, wherein the first water flow temperature sensor is disposed in the inlet pipe and the second water flow temperature sensor is disposed in the return pipe;
[0009] The electromagnetic proportional valve is electrically connected to the first water flow temperature sensor and the second water flow temperature sensor, respectively.
[0010] In one embodiment, the water temperature control mechanism further includes a pneumatic angle valve, which includes a first pneumatic angle valve and a second pneumatic angle valve. The first pneumatic angle valve is located in the inlet pipe and is connected to the first water flow temperature sensor; the second pneumatic angle valve is located in the return pipe and is connected to the second water flow temperature sensor.
[0011] In one embodiment, the water inlet assembly further includes a first connector that connects the first water flow temperature sensor and the electromagnetic proportional valve.
[0012] In one embodiment, the water inlet assembly further includes an air inlet pipe and a pressure sensor. The water inlet pipe and the pressure sensor are both located in the water inlet pipe. The air inlet pipe is located between the pneumatic angle valve and the pressure sensor and is connected to the water inlet pipe.
[0013] In one embodiment, the air intake pipe is provided with two first check valves, each of which is spaced apart in the air intake pipe, wherein one of the first check valves is located close to the water intake pipe.
[0014] In one embodiment, the water return assembly further includes a second check valve, which is disposed between the pneumatic angle valve and the product.
[0015] This utility model also proposes an integrated water circuit temperature control mechanism, which includes:
[0016] Multiple water temperature control mechanisms as described above;
[0017] The water collection pipe includes an inlet water collection pipe and an outlet water collection pipe. The inlet component of each water circuit temperature control mechanism is connected to the inlet water collection pipe, and the return water component of each water circuit temperature control mechanism is connected to the outlet water collection pipe.
[0018] In one embodiment, the inlet components of each water circuit temperature control mechanism are spaced apart on the inlet water collection pipe, and the return water components of each water circuit temperature control mechanism are spaced apart on the outlet water collection pipe. The inlet component of each water circuit temperature control mechanism is correspondingly arranged with the return water component of the water circuit temperature control mechanism.
[0019] This invention's technical solution involves setting up an inlet water assembly and a return water assembly, with a water flow temperature sensor installed in both the inlet and return water pipes. The water flow temperature sensor performs real-time temperature monitoring. The inlet water assembly also includes an electromagnetic proportional valve. The water flow temperature sensor determines whether the water temperature meets a set standard and controls the opening of the electromagnetic proportional valve to regulate the flow rate of water through the test product, thereby controlling the product's outlet water temperature. This setup adjusts the water flow based on real-time temperature data, ensuring the operating temperature of the aging test product remains within a predetermined range, thus improving the reliability and efficiency of the test.

[0030] This utility model proposes a water circuit temperature control mechanism 100.
[0031] Please see Figures 1 to 3 In one embodiment of this utility model, the water circuit temperature control mechanism is used for aging test products. The water circuit temperature control mechanism includes a water tank with an outlet and a return outlet. In another embodiment of this utility model, the water circuit temperature control mechanism further includes an inlet component 1, a return component 2, and a water flow temperature sensor. The inlet component 1 includes an inlet pipe 11 and an electromagnetic proportional valve 12. The electromagnetic proportional valve 12 connects the outlet and the inlet pipe 11, and one end of the inlet pipe 11 connects to the product. The return component 2 includes a return pipe 21, and both ends of the return pipe 21 are connected to the return outlet and the product, respectively. The water flow temperature sensor includes a first water flow temperature sensor 31 and a second water flow temperature sensor 32. The first water flow temperature sensor 31 is located in the inlet pipe 11, and the second water flow temperature sensor 32 is located in the return pipe 21. The electromagnetic proportional valve 12 is electrically connected to the first water flow temperature sensor 31 and the second water flow temperature sensor 32, respectively.
[0032] In this embodiment, the water temperature control mechanism is used for aging testing, the water tank provides a buffer for water source and temperature regulation, the inlet water assembly 1 controls and regulates the water temperature and introduces water into the product to ensure that the water temperature entering the test product meets the requirements, and the return water assembly 2 recovers the water flowing through the product and detects the water flow temperature to achieve water circulation. A water flow temperature sensor is used for real-time temperature monitoring. Accordingly, the first water flow temperature sensor 31 is installed in the inlet pipe 11 to monitor the water temperature flowing into the test product in real time; the second water flow temperature sensor 32 is installed in the return water pipe 21 to detect the water temperature after passing through the test product. Furthermore, the opening degree of the electromagnetic proportional valve 12 is used to control the water flow rate, thereby controlling the product outlet water temperature. When the water temperature exceeds the range, the opening degree of the proportional valve is increased to cool down; when the water temperature is below the range, the opening degree of the proportional valve is decreased to heat up. By controlling the product outlet water temperature in the above manner, the product will undergo aging testing in a stable water temperature environment.
[0033] The technical solution of this utility model involves setting up an inlet water assembly 1 and a return water assembly 2, and installing a water flow temperature sensor in the inlet water pipe 11 and the return water pipe 21 respectively. The water flow temperature sensor performs real-time temperature monitoring. The inlet water assembly 1 also includes an electromagnetic proportional valve 12. The water flow temperature sensor determines whether the water temperature meets the set standard, and controls the opening degree of the electromagnetic proportional valve 12 to control the flow rate of water through the test product, thereby controlling the product's outlet water temperature. This setup can adjust the water flow based on real-time temperature data, ensuring that the operating temperature of the aging test product remains within the predetermined range, thus improving the reliability and efficiency of the test.
[0034] In one embodiment of this utility model, the water temperature control mechanism further includes a pneumatic angle valve, which includes a first pneumatic angle valve 17 and a second pneumatic angle valve 22. The first pneumatic angle valve 17 is located in the water inlet pipe 11 and is connected to the first water flow temperature sensor 31; the second pneumatic angle valve 22 is located in the water return pipe 21 and is connected to the second water flow temperature sensor 32.
[0035] Combination Figure 2 and Figure 3In this embodiment, the pneumatic angle valve works in conjunction with the electromagnetic proportional valve 12 to accurately control the liquid flow rate through pneumatic control, thereby achieving precise temperature control. Accordingly, the pneumatic angle valve can be a single-acting or double-acting pneumatic angle valve; no limitation is made here. The first pneumatic angle valve 17 and the second pneumatic angle valve 22 are respectively connected to the first water flow temperature sensor 31 and the second water flow temperature sensor 32, forming two feedback control loops. The electromagnetic proportional valve 12 adjusts its opening degree based on the feedback signals from these two sensors, achieving closed-loop control of the water temperature. Further, after the test is completed, residual water in the product needs to be cleaned by blowing water through the air inlet pipe 14. At this time, the first pneumatic angle valve 17 needs to be closed. After blowing water is completed, the air inlet pipe 14 stops supplying air, and the second pneumatic angle valve 22 is closed. The product is then removed from the test unit, and the product test is complete. The above setup helps to automatically control the water circuit temperature, improving the automation level of the entire aging test process.
[0036] In one embodiment of the present invention, the water inlet assembly 1 further includes a first connector 13, which is connected to a first water flow temperature sensor and an electromagnetic proportional valve 12.
[0037] Combination Figure 2 In this embodiment, the first connector 13 serves as a connecting element. The electromagnetic proportional valve 12 automatically adjusts its opening degree based on the electrical signal from the first water flow temperature sensor 31, thereby controlling the water flow rate into the product. This adjustment is proportional, meaning the valve opening degree is proportional to the temperature deviation, to achieve precise control of the water temperature. This configuration facilitates real-time monitoring and precise control of the inlet water temperature, thereby ensuring temperature stability and consistency during the aging test.
[0038] In one embodiment of the present invention, the water inlet assembly 1 further includes an air inlet pipe 14 and a pressure sensor 16. The water inlet pipe 11 and the pressure sensor 16 are both located in the water inlet pipe 11. The air inlet pipe 14 is located between the pneumatic angle valve and the pressure sensor 16 and is connected to the water inlet pipe 11.
[0039] Combination Figure 2In this embodiment, to test the sealing of the water system, an air intake pipe 14 and a pressure sensor 16 are installed for a sealing test. The pressure sensor 16 is used to monitor the pressure changes in the pipe in real time during the sealing test. Accordingly, the air intake pipe 14 is connected to the water inlet pipe 11 through a fitting, which can be an internal thread tee. Further, when the sealing test begins, the pneumatic angle valve is in the closed state, and the air intake pipe 14 begins to intake air through the opening of the electromagnetic proportional valve 12. When the pressure sensor 16 senses that the air pressure reaches a certain level, the air intake stops and pressure is maintained. The pressure value of the pressure sensor 16 is monitored for any decrease or change. If the pressure value remains stable without any decrease or change, it indicates that the water inlet pipe 11 has good sealing performance. The above setup can effectively perform sealing tests without actually operating the water system, ensuring the reliability and safety of the system. It is suitable not only for post-installation testing but also for regular maintenance and inspection to prevent potential leakage problems.
[0040] In one embodiment of the present invention, the air intake pipe 14 is provided with two first check valves 15, and each first check valve 15 is distributed at intervals in the air intake pipe 14, wherein one of the first check valves 15 is located close to the water intake pipe 11.
[0041] Combination Figure 2 In this embodiment, to prevent water from entering the air intake pipe 14 when the water circuit is connected, two first check valves 15 are provided for double water ingress prevention. Even if one first check valve 15 fails, the other can still prevent backflow. One of the first check valves 15 is located near the water intake pipe 11 to prevent water from flowing back into the pneumatic system, avoiding damage to the air intake pipe 14 due to water vapor intrusion and extending the service life of the air intake pipe 14.
[0042] In one embodiment of the present invention, the water return assembly 2 further includes a second check valve, which is disposed between the pneumatic angle valve and the product.
[0043] Combination Figure 3 In this embodiment, the second check valve is used to ensure that the water flow can only flow in the set direction, i.e., from the inlet direction to the return direction. The above-mentioned arrangement helps to prevent water backflow and also helps to maintain the water pressure balance in the system. Preventing backflow can avoid the water pressure drop in the return pipe 21 and ensure the normal operation of the system.
[0044] This utility model also proposes an integrated water circuit temperature control mechanism, which includes the water circuit temperature control mechanism and the water collection pipe described above. The specific structure of the water circuit temperature control mechanism is as described in the above embodiments. Since this integrated water circuit temperature control mechanism adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The water collection pipe includes an inlet water collection pipe 210 and an outlet water collection pipe 220. The inlet component 1 of each water circuit temperature control mechanism is connected to the inlet water collection pipe 210, and the return water component 2 of each water circuit temperature control mechanism is connected to the outlet water collection pipe 220.
[0045] In this embodiment, by setting up the inlet water collection pipe 210 and the outlet water collection pipe 220, centralized management of multiple water circuit temperature control mechanisms can be achieved, while water flow can be efficiently distributed among the various water flow temperature control mechanisms, improving water circulation efficiency. Furthermore, the inlet water collection pipe 210 and the outlet water collection pipe 220 can be connected to multiple water circuit temperature control mechanisms, enabling simultaneous water aging tests on multiple products, thus improving testing efficiency.
[0046] In one embodiment of this utility model, the water inlet components 1 of each water circuit temperature control mechanism are spaced apart on the water inlet collection pipe 210, and the water return components 2 of each water circuit temperature control mechanism are spaced apart on the water outlet collection pipe 220. The water inlet component 1 of each water circuit temperature control mechanism is correspondingly arranged with the water return component 2 of the same water circuit temperature control mechanism.
[0047] In this embodiment, the spaced distribution helps to create a uniform pressure distribution in the water collection pipe, ensuring that each water circuit temperature control mechanism operates under the same pressure conditions and guaranteeing the accuracy of temperature control. This arrangement ensures that the water flow of each water flow temperature control mechanism is independent and does not interfere with each other, allowing for precise control of the water flow and temperature of each circulation structure; it also facilitates maintenance.
[0048] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
