Description

Technical Field

[0001] This utility model relates to the field of water-cooled plate testing technology, specifically to a sealing testing device for water-cooled plates in new energy vehicles. Background Technology

[0002] Water-cooled plates for new energy vehicles are key components used in electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs) to cool battery packs or electric motors. Since battery packs and electric motors generate a significant amount of heat during operation, the function of the water-cooled plate is to cool these critical components through liquid circulation, ensuring that the battery and electric motor operate within their optimal temperature range. This extends battery life, improves system efficiency, and ensures vehicle safety. During the manufacturing process of water-cooled plates, a sealing test is required.

[0003] Traditional methods for testing the sealing of water-cooled plates mainly include water testing and dyeing. Water testing involves injecting water into the water-cooled plate and observing for leaks, but the plate needs to be dried after testing, making it inefficient and potentially leaving residual moisture. Dyeing uses chemical reagents, which improves the visibility of leak points, but carries the risk of chemical residues that may corrode the water-cooled plate material and does not meet environmental protection requirements. Furthermore, traditional testing methods typically only test one water-cooled plate at a time, resulting in low testing efficiency. Utility Model Content

[0004] The technical problem this utility model aims to solve is as follows: Traditional methods for detecting the sealing of water-cooled plates mainly include water testing and dyeing. Water testing involves injecting water into the water-cooled plate and observing for leaks, but the plate needs to be dried after testing, resulting in low efficiency and potential moisture residue. Dyeing uses chemical reagents for detection, which improves the visibility of leak points, but carries the risk of chemical residues that may corrode the water-cooled plate material and does not meet environmental protection requirements. Furthermore, traditional testing methods typically only test one water-cooled plate at a time, resulting in low testing efficiency.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A sealing testing device for water-cooled plates in new energy vehicles includes a testing box. An inert gas tank is fixedly installed on one side of the outer surface of the testing box. The output end of the inert gas tank is connected to a multi-station testing mechanism. Cavities are formed on both sides of the inner wall of the testing box. A heating mechanism is fixedly installed inside the cavity. A limiting plate is fixedly installed on one side of the inner wall of the testing box. A water-cooled plate is inserted into the limiting plate. A box cover is snapped onto the top surface of the testing box. Mounting grooves are formed on both sides of the top surface of the box cover. A heat dissipation mechanism is fixedly installed inside the mounting grooves.

[0007] As a further embodiment of this utility model: the multi-station detection mechanism includes a gas supply pipe, a gas distribution pipe and a pressure sensor. One end of the gas supply pipe is connected to the output end of the inert gas tank. There are three sets of gas distribution pipes, which are axially connected to the surface of the gas supply pipe. The pressure sensor is fixedly installed on the surface of the gas distribution pipe. The multi-station detection mechanism is used to detect multiple sets of water-cooled plates simultaneously.

[0008] As a further embodiment of this utility model: a main valve is fixedly installed on the side of the gas supply pipe near the inert gas tank, and a secondary valve is fixedly installed on the surface of the gas distribution pipe, the secondary valve controlling the opening and closing of the gas distribution pipe.

[0009] As a further embodiment of this utility model: the heating mechanism includes a heating plate and a temperature controller. The heating plate is fixedly disposed inside the cavity, and the temperature controller is fixedly installed on the surface of the test chamber and electrically connected to the heating plate. The heating mechanism is used to heat the inside of the test chamber.

[0010] As a further embodiment of this utility model: the heat dissipation mechanism includes a heat dissipation fan and a cover plate. The heat dissipation fan is fixedly installed inside the mounting groove, and the cover plate is snapped onto the top surface of the mounting groove to close the mounting groove.

[0011] As a further embodiment of this utility model: A handle A is fixedly provided on the top surface of the cover plate, and B handles are fixedly provided on both sides of the top surface of the box cover. The B handles are used to open and close the box cover.

[0012] As a further embodiment of this utility model: the number of limiting plates and water-cooling plates is three sets, and the three sets of limiting plates and water-cooling plates are arranged sequentially along the axial direction. The limiting plates are used to place the water-cooling plates.

[0013] The beneficial effects of this utility model are:

By setting up a multi-station testing mechanism, three sets of water-cooled plates are placed inside the limiting plate, the outlet of the water-cooled plates is sealed, the inlet is connected to the gas distribution pipe, the main valve and the auxiliary valve are opened, and the inert gas in the inert gas tank is transported to the water-cooled plates through the gas supply pipe and the gas distribution pipe. After the transportation is completed, the main valve and the auxiliary valve are closed. The pressure sensor senses the pressure change of the water-cooled plates. When the pressure changes, it indicates that the water-cooled plates are not sealed tightly. This achieves the effect of simultaneously testing the seal of multiple sets of water-cooled plates, improving the testing effect. Moreover, using inert gas as the testing medium is more convenient and environmentally friendly compared to the traditional water testing method, which requires drying after testing, and the dyeing method, which leaves chemical residues.

[0024] like Figure 1-5As shown, a sealing test device for water-cooled plates in new energy vehicles includes a test box 1. An inert gas tank 2 is fixedly installed on one side of the outer surface of the test box 1. The output end of the inert gas tank 2 is connected to a multi-station test mechanism 3. Through the setting of the multi-station test mechanism 3, three sets of water-cooled plates 6 are placed in a limiting plate 5, the outlet of the water-cooled plate 6 is closed, and the inlet is connected to a gas distribution pipe 302. The main valve 9 and the auxiliary valve 10 are opened, and the inert gas in the inert gas tank 2 is transported to the water-cooled plate 6 through the gas supply pipe 301 and the gas distribution pipe 302. After the transportation is completed, the main valve 9 and the auxiliary valve 10 are closed. The pressure sensor 303 senses the pressure change of the water-cooled plate 6. When the pressure changes, it indicates that the water-cooled plate 6 is not sealed tightly. This device achieves the effect of simultaneously testing the sealing of multiple sets of water-cooled plates 6, improving the test effect. Moreover, using inert gas as the test medium is more convenient and environmentally friendly than the traditional water test method, which requires drying after the test, and the dyeing method, which leaves chemical residues.

[0025] The inner wall of the testing chamber 1 has cavities on both sides, and a heating mechanism 4 is fixedly installed inside the cavity. A limit plate 5 is fixedly installed on one side of the inner wall of the testing chamber 1, and a water-cooling plate 6 is inserted into the limit plate 5. A cover 7 is snapped onto the top surface of the testing chamber 1. There are mounting grooves on both sides of the top surface of the cover 7, and a heat dissipation mechanism 8 is fixedly installed inside the mounting groove. With the setting of the heating mechanism 4 and the heat dissipation mechanism 8, the heating plate 401 is energized to heat the water-cooling plate 6 inside the testing chamber 1 to simulate a high-temperature environment and test the sealing performance of the water-cooling plate 6. After the test is completed, the cover 802 is opened, and the cooling fan 801 accelerates the heat dissipation inside the testing chamber 1, so that the water-cooling plate 6 cools down quickly, making it easy for personnel to remove the water-cooling plate 6 after the test is completed and avoid burns.

[0026] like Figure 4 As shown, the multi-station detection mechanism 3 includes an air supply pipe 301, an air distribution pipe 302, and a pressure sensor 303. One end of the air supply pipe 301 is connected to the output end of the inert gas tank 2. There are three sets of air distribution pipes 302, which are connected to the surface of the air supply pipe 301 along the axial direction. The pressure sensor 303 is fixedly installed on the surface of the air distribution pipe 302.

[0027] The multi-station testing mechanism 3 enables simultaneous testing of multiple sets of water-cooled plates 6.

[0028] like Figure 4 As shown, a main valve 9 is fixedly installed on the surface of the gas supply pipe 301 near the inert gas tank 2, and a secondary valve 10 is fixedly installed on the surface of the gas distribution pipe 302.

[0029] With the main valve 9 and the auxiliary valve 10 set, the main valve 9 controls the opening and closing of the gas supply pipe 301, and the auxiliary valve 10 controls the opening and closing of the gas distribution pipe 302.

[0030] like Figure 5As shown, the heating mechanism 4 includes a heating plate 401 and a temperature controller 402. The heating plate 401 is fixedly disposed inside the cavity, and the temperature controller 402 is fixedly installed on the surface of the detection box 1 and electrically connected to the heating plate 401.

[0031] The heating mechanism 4 is designed to simulate a high-temperature environment.

[0032] like Figure 3 As shown, the heat dissipation mechanism 8 includes a heat dissipation fan 801 and a cover plate 802. The heat dissipation fan 801 is fixedly installed inside the mounting slot, and the cover plate 802 is snapped onto the top surface of the mounting slot.

[0033] The heat dissipation mechanism 8 is designed to quickly dissipate heat from inside the detection box 1.

[0034] like Figure 3 As shown, a handle 11 A is fixedly installed on the top surface of the cover plate 802, and handles 12 B are fixedly installed on both sides of the top surface of the box cover 7.

[0035] The handle 12 (B) serves to open and close the lid 7.

[0036] like Figure 2 As shown, there are three sets of limiting plates 5 and water-cooling plates 6, and the three sets of limiting plates 5 and water-cooling plates 6 are arranged sequentially along the axial direction.

[0037] The limiting plate 5 serves to limit the movement of the water-cooled plate 6.

[0038] The model of pressure sensor 303 is Famit FMT2088. The above parameters and model can be selected according to the actual situation.

[0039] The working principle of this utility model is as follows: Three sets of water-cooled plates 6 are placed inside the limiting plate 5, the outlet of the water-cooled plate 6 is closed, the inlet is connected to the gas distribution pipe 302, the main valve 9 and the auxiliary valve 10 are opened, and the inert gas in the inert gas tank 2 is transported to the water-cooled plate 6 through the gas supply pipe 301 and the gas distribution pipe 302. After the transportation is completed, the main valve 9 and the auxiliary valve 10 are closed. The pressure sensor 303 senses the pressure change of the water-cooled plate 6. When the pressure changes, it indicates that the water-cooled plate 6 is not sealed tightly. At the same time, multiple sets of water-cooled plates 6 can be sealed, which improves the detection effect. Moreover, the use of inert gas as the detection medium is more convenient and environmentally friendly than the traditional water detection method, which requires drying after detection, and the dyeing method, which leaves chemical residues.

[0040] After the heating plate 401 is powered on, it heats the water-cooled plate 6 inside the test chamber 1 to simulate a high-temperature environment and test the sealing performance of the water-cooled plate 6. After the test is completed, the cover plate 802 is opened and the cooling fan 801 accelerates the heat dissipation inside the test chamber 1, so that the water-cooled plate 6 cools down quickly, making it easy for personnel to remove the water-cooled plate 6 after the test is completed and avoid burns.
