[0035] The setting of the hood 84 integrates the water storage module 1, the heating module 2 and the cooling module 3 in one shell, thereby achieving a protective effect.

[0036] The utility model discloses, realized reliable control water temperature rise and fall's effect, make water temperature always can keep in the required numerical value and carry out aging constant current test to product 7, thereby guarantee the test effect.

[0037] In the embodiment, the water storage module 1 includes a water tank 11 and a water supplement mechanism 12, the water tank 11 is provided with a temperature sensor 111, a water supplement opening 112 and a water level sensing element 113, the temperature sensor 111 is used for sensing the water temperature in the water tank 11, the water supplement mechanism 12 is communicated with the water tank 11 through the water supplement opening 112, and the water level sensing element 113 is used for displaying the water level in the water tank 11.

[0038] That is, the utility model stores water through the water tank 11, and the temperature sensor 111 is used for sensing to infer whether the temperature of water entering the product 7 is within the required value, and the inference mode belongs to a conventional algorithm, which will not be described here. In addition, the water level sensing element 113 can be preferably a transparent tube communicated with the water tank 11, and the water level in the water tank 11 is monitored by using the principle of communicating vessels; when the water level is lower than the preset value due to water loss in the experimental process, the water tank 11 is supplemented by the water supplement mechanism 12, so that the water in the water tank 11 can reliably perform the aging constant current test.

[0039] Specifically, the water supplement mechanism 12 includes a pure water machine 13, a water filter 14, a water supplement pump 15 arranged in the power layer 81 and a water supplement ball valve 16 arranged in the control layer 83, the pure water machine 13, the water supplement ball valve 16, the water filter 14 and the water supplement pump 15 are communicated, and the water supplement pump 15 is communicated with the water supplement opening 112.

[0040] The pure water machine 13 is also connected with an overflow valve 17 and a water inlet valve 18 arranged in the control layer 83, wherein the overflow valve 17 is used for timely discharging water when the water in the pure water machine is excessive, and the pure water machine 13 is externally connected with a water source through the water inlet valve 18.

[0041] The pure water machine 13 is used for externally connecting a water source, and the water amount in the pure water machine 13 can be kept sufficient by manual water adding or other modes; when water supplement is needed, the water supplement ball valve 16 and the water supplement pump 15 are both opened, and under the action of the water supplement pump 15, water enters the water filter 14 after being filtered by the pure water machine 13 and then enters the water tank 11, and the water is further filtered by the water filter 14, so as to ensure the purity of the water and avoid affecting the aging test effect.

[0042] In the embodiment, the heating module 2 includes an external circulating pump 21 and an electric heating device 22, the external circulating pump 21 is arranged between the water tank 11 and the electric heating device 22, the electric heating device 22 is communicated with the water supply module 4, and the external circulating pump 21 is arranged in the power layer 81.

[0043] The electric heating device 22 can use electric heating wires or other conventional heating methods to heat the water. The electric heating device 22 needs to have a channel for water to flow. During the aging test, the external circulation pump 21 is used to drive the water along a predetermined path. This path is connected to the product 7 to ensure that the water can enter the product 7 and then flow out.

[0044] In this embodiment, the water supply module 4 includes a water outlet component 41 and a return water component 42, both of which are arranged on the test layer 82. The water outlet component 41 has at least one water outlet 43. The input end of the water outlet component 41 is connected to the heating module 2. Each water outlet 43 is respectively connected to the air supply module 6. The water outlet 43 is also used for external product 7; one end of the return water component 42 is used for external product 7, and the other end of the return water component 42 is connected to the water storage module 1. The air supply module 6 is used to supply air to the product 7 to send the water in the product 7 into the return water component 42.

[0045] In this embodiment, the water outlet member 41 has four water outlets 43, each connected to an air supply module 6 and capable of communicating with a product 7. The other end of each product 7 is connected to a water return member 42, which can be a multi-way or other commonly used communication structure. This means that the present invention can perform aging tests on multiple products 7 at once. After each test, the water inside the product 7 is squeezed into the water return member 42 via the air supply module 6, minimizing water waste and preventing safety risks associated with water trapped inside the product 7.

[0046] In this embodiment Figure 5 In order to facilitate reference and understanding, only the structure of one air supply module 6 is shown. Figure 5 This should not be construed as limiting the scope of protection of the present invention. Furthermore, the water storage module 1 may include an exhaust valve for promptly discharging excess gas when the internal pressure of the water tank 11 is high; and corresponding flow control valves 47 are provided at the locations connected to the product 7, for isolating the present invention from the outside world through the flow control valves 47 when the product 7 is replaced, thereby preventing water leakage.

[0047] Specifically, the return member 42 is provided with a filter 44, and the water outlet member 41 is connected to a manual valve 45, which is in communication with the water tank 11. The filter 44 is used to filter the water flowing out of the product 7, thereby filtering out impurities carried by the water from the product 7. In addition, the manual valve 45 is preferably a ball valve, which is used to open when the water pressure in the water outlet member 41 is too high, allowing some water to flow back into the water tank 11, ensuring safety.

[0048] Specifically, the water outlet 43 is connected to the conveying part 46, the conveying part 46 is provided with a water pressure switch 48, the air supply module 6 includes an air inlet part 61, a constant pressure tank 62, a control valve assembly 63 and a pressure gauge 64, the air inlet part 61 is connected to the conveying part 46 after passing through the constant pressure tank 62 and the control valve assembly 63, and the pressure gauge 64 is used to sense the air pressure value of the air inlet part 61; wherein, the control valve assembly 63 is arranged in the control layer 83.

[0049] The conveying part 46 is a pipeline, that is, after the aging test is completed, the external circulation pump 21 stops working, the water pressure switch is closed due to the decrease in water pressure, and then the control valve assembly 63 is opened, allowing the outside gas to enter the product 7 through the air inlet part 61, the control valve assembly 63, and the conveying part 46, thereby pressing the water in the product 7 into the return water part 42, achieving the drainage effect for the product 7; in the drainage process, the constant pressure tank 62 is used to compensate for the air pressure change, that is, when the air pressure is high, excess gas enters the constant pressure tank 62, and when the air pressure is low, the constant pressure tank 62 performs gas transportation; at the same time, the pressure gauge 64 is used to monitor the air pressure value, so that the staff can make adjustments when the air pressure is abnormal.

[0050] Specifically, the control valve assembly 63 includes a first control valve 65 and a second control valve 66. The two ends of the first control valve 65 are respectively connected to the constant pressure tank 62 and the water supply module 4. The second control valve 66 and the first control valve 65 are connected in parallel between the constant pressure tank 62 and the water supply module 4. The maximum flow of the first control valve 61 is greater than the maximum flow of the second control valve 62.

[0051] In actual use, the first and second control valves 65, 66 are both solenoid valves, and a one-way valve 67 is provided between the end of the control valve assembly 63 and the water supply module 4. Initially, the first control valve 65 is opened and the second control valve 66 is closed, allowing a large flow of gas to quickly enter the product 7, thereby squeezing out the water within the product 7. When the gas within the product 7 reaches a certain level, the second control valve 66 is opened and the first control valve 65 is closed, allowing a small flow of gas to gradually fill the interior of the product 7. This ensures that the remaining water steadily enters the water injection module, preventing the internal air pressure of the product 7 from increasing too quickly and causing damage to the product 7.

[0052] In this embodiment, the cooling module 3 includes a first heat exchanger 32, a second heat exchanger 33 and a drive mechanism 34. The first heat exchanger 32 has two heat exchange ends, one of which forms a circulating water circuit with the on-off module 5 and the water storage module 1, and the other heat exchange end forms a closed loop with the second heat exchanger 33 and the drive mechanism 34. The second heat exchanger 33 is used to connect to an external cooling water source.

[0053] The closed loop contains a gaseous medium for heat exchange, and the driving mechanism 34 is used to drive the flow of the gaseous medium in the closed loop.

[0054] The cooling of the present invention is achieved through a gaseous medium, that is, external cold water and the gaseous medium perform heat exchange in the second heat exchanger 33, so that after the temperature of the gaseous medium is reduced, the gaseous medium flows into the first heat exchanger 32, exchanges heat with the water inside the first heat exchanger 32, so that the water in the first heat exchanger 32 is cooled. The cooled water then flows into the water tank 11 and mixes with the water with a higher temperature in the water tank 11, thereby achieving the effect of lowering the water temperature in the water tank 11.

[0055] Specifically, the cooling module 3 further includes a thermal expansion valve 35 and a drying filter 36 . The thermal expansion valve 35 and the drying filter 36 are both arranged in a closed loop. The thermal expansion valve 35 is used to balance the temperature of the gaseous medium at both ends of the second heat exchanger 33 .

[0056] The drying filter 36 is used to dry the gaseous medium within the closed loop to ensure that the gaseous medium does not contain impurities such as water, which could affect the heat exchange effect. The drive mechanism 34 is primarily composed of an air pump 37 and an oil separator 38. Specifically, the air pump 37 is positioned between the first heat exchanger 32 and the oil separator 38, and the oil separator 38 is positioned between the air pump 37 and the second heat exchanger 33 to ensure that the gaseous medium does not contain oil, which could pose a safety risk. Specifically, the drive mechanism 34 is positioned within the test floor 82 and outside the hood 84, enabling more efficient use of the space within the test floor 82 and preventing heat generated by the drive mechanism 34 from affecting components within the hood 84.

[0057] The thermal expansion valve 35 of the present invention has two normally open ends and one normally closed end. The two normally open ends are connected to the filter drier 36 and the drive mechanism 34, respectively, while the normally closed end is located between the first heat exchanger 32 and the air pump 37. When the temperature of the gaseous medium at the two normally open ends differs significantly from the temperature of the gaseous medium at the normally closed end, the normally closed end opens to allow the gaseous medium at the two normally open ends to flow to the normally closed end, thereby reducing the temperature of the gaseous medium at the normally closed end. Subsequently, the gaseous medium at the normally closed end can be further cooled when exchanging heat with the cooling water in the second heat exchanger 33, thereby ensuring a cooling effect.

[0058] In this embodiment, a pulley 86 and a locking module 87 for locking the pulley 86 are provided at the bottom of the body 1, so that the utility model is easy to move.

[0059] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application is disclosed as above in the preferred embodiment, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the disclosed technical content without departing from the technical solution of the present application, and any equivalent embodiment with equivalent changes is equivalent to the above embodiment.
