Description

Technical Field

[0001] This utility model relates to the field of water-cooled plate sealing test technology, specifically to a novel quick-connect sealing helium test workpiece. Background Technology

[0002] With the deepening of national regulations on thermal management of new energy vehicles, the new energy vehicle industry has received increasing attention. As the heart of new energy vehicles, the safety, lifespan, driving range, and performance of power batteries have become a focus of attention for users. To improve battery performance, extend CFD calculation lifespan, increase vehicle driving range, and prevent power battery safety accidents, battery operating temperature has become a key factor.

[0003] Among various battery cooling solutions, liquid cooling, with its large specific heat capacity and high heat transfer coefficient, has become the mainstream cooling method, surpassing air cooling and phase change cooling. The heat generated by the power battery during operation is transferred through contact between electronic components and the surface of a plate-shaped aluminum device, ultimately being carried away by the coolant flowing through the internal channels of the device plate; this plate-shaped aluminum device is the water-cooled plate. To ensure the good thermal conductivity of the water-cooled plate and facilitate the removal of heat generated by the battery, the principle is to create flow channels within the metal plate. Electronic components are mounted on the surface of the metal plate, and coolant flows out from the inlet, thus carrying away the heat generated by the components. According to the national standard GB38031-2020 "Safety Requirements for Power Batteries of Electric Vehicles" IP67 standard, during the production process, not only the airtightness of the battery and battery pack must be tested, but also the airtightness of the water-cooled plate, as its sealing performance directly affects the safety and power performance of the entire vehicle.

[0004] Currently, the sealing performance of water-cooled plates is generally tested using helium gas detection. This requires placing the product in a vacuum chamber for testing, with the internal test pressure typically between 0.2-2 MPa. The water-cooled plate must first be evacuated before helium gas is introduced for the helium gas test. However, this testing technique commonly suffers from micro-leakage at the sealing surface, leading to non-compliance tests and impacting the testing schedule. While some solutions on the market use screws to seal the helium-tested workpiece, this method increases operational difficulty and processing time. Utility Model Content

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figures 1-2 As shown, this utility model provides a novel quick-connect sealed helium inspection workpiece, including a fixing buckle 1 and a quick-connect sealing connector 2. The quick-connect sealing connector 2 is used to connect to the interface of the current collector 3. The bottom of the fixing buckle 1 has a slot, which engages with the current collector 3 and simultaneously engages the quick-connect sealing connector 2. The slot is adapted to the outer surface of the current collector 3, and the fixing buckle 1 achieves a quick insertion and removal effect through the slot and the gap fit between the current collector 3 and the current collector 3. This facilitates installation and reduces the difficulty and time of installation. The current collector 3 is connected to the surface of the water-cooled plate 4.

[0025] Furthermore, in actual production, the fixing buckle 1 can be provided with anti-slip textures on its two opposing surfaces as needed, so as to facilitate the insertion and removal of the fixing buckle 1.

[0026] As a further step, one end face of the fixing buckle 1 is provided with a U-shaped opening 5 that communicates with the bottom groove of the fixing buckle 1. The quick-connect sealing connector 2 is located inside the U-shaped opening 5 and is connected to the interface of the collector 3. The interface on the collector 3 communicates with the flow channel in the water-cooled plate 4. The interface on the collector 3 includes a first interface 31 and a second interface 32. The first interface 31 and the second interface 32 are respectively connected to the inlet and outlet of the flow channel in the water-cooled plate 4.

[0027] Furthermore, the quick-connect sealing connector 2 includes a first connector 21 and a second connector 22. The diameters of the first connector 21 and the second connector 22 are equal. A limiting ring 6 is provided on the end of the first connector 21 that is connected to the first interface 31. When the first connector 21 is connected to the first interface 31, one end face of the limiting ring 6 can abut against the outer wall of the collector 3. An internally threaded cylinder 7 is provided on the end of the second connector 22 that is connected to the second interface 32. When the internally threaded cylinder 7 is sleeved on the second interface 32, one end face of it can abut against the outer wall of the collector 3. The outer diameter of the limiting ring 6 is equal to the outer diameter of the internally threaded cylinder 7.

[0028] Combination Figure 2 As shown, one end of the first connector 21 is inserted into the first interface 31, and a sealing ring is fitted on one end of the first connector 21. After the first end of the first connector 21 is inserted into the first interface 31 through the sealing ring, the connection between the first connector 21 and the collector 3 can be sealed.

[0029] Combination Figure 2 As shown, the second interface 32 is a protruding interface, and a sealing ring is provided on the outer surface of the interface. One end of the second connector 22 is sleeved on the second interface 32. The second connector 22 is sleeved with the second interface 32 through the internal threaded cylinder 7. When the internal threaded cylinder 7 is connected to the second interface 32, the sealing ring on the outer wall of the second interface 32 is used to ensure the sealing of the connection between the second connector 22 and the collector 3.

[0030] As a further step, two U-shaped openings 5 ​​are provided, and the two U-shaped openings 5 ​​are respectively locked onto the corresponding first connector 21 and second connector 22. One side of the limiting ring 6 and the internal threaded cylinder 7 respectively abuts against the inner wall of the bottom groove of the fixing buckle 1. The inner dimensions and height of the two U-shaped openings 5 ​​are the same, which is conducive to the fixing buckle 1 to stably lock the quick-connect sealing connector 2 into the U-shaped opening 5. At the same time, with the design of the abutting limiting ring 6 and the internal threaded cylinder 7, the sealing performance of the quick-connect sealing connector 2 after being connected to the manifold 3 is effectively guaranteed, preventing micro-leakage, increasing the sealing effect, and reducing the amount of helium leakage.

[0031] Furthermore, combining Figure 1 and Figure 2As shown, the longitudinal section of the fixing buckle 1 is L-shaped, and two U-shaped openings 5 ​​are parallel to each other and are respectively opened on the convex and concave surfaces of the L-shaped fixing buckle 1. The U-shaped openings 5 ​​include a first opening 51 and a second opening 52. The first opening 51 is opened on the concave surface of the fixing buckle 1, and the first connector 21 is located inside the first opening 51. The second opening 52 is opened on the convex surface of the fixing buckle 1, and the second connector 22 is located inside the second opening 52.

[0032] Specifically, because the second interface 32 is a protruding design, and the first connector 21 is inserted into the first interface 31, the L-shaped fixing buckle 1 can fully match the first connector 21 and the second connector 22. This ensures that when the fixing buckle 1 is pressed down and assembled onto the collector 3, the slot at the bottom of the fixing buckle 1 can limit one end of the first connector 21 and the second connector 22, preventing micro-leakage at the quick-connect sealing connector 2 and the collector 3, and effectively improving the accuracy and efficiency of the detection.

[0033] The working principle and usage process of this utility model are as follows: When in use, the operator first assembles the quick-connect sealing connector 2 onto the manifold 3, and then presses down the fixing buckle 1 onto the manifold 3. During this process, the two quick-connect sealing connectors 2 are respectively set in the corresponding U-shaped openings 5, and one side of the limiting ring 6 and the internal threaded cylinder 7 can respectively abut against the inner wall of the slot at the bottom of the fixing buckle 1, ensuring the connection stability between the quick-connect sealing connector 2 and the manifold 3. At the same time, the sealing ring design improves the sealing performance between the quick-connect sealing connector 2 and the manifold 3, which is conducive to the stable helium gas tightness test of the water-cooled plate 4.

[0034] In summary, the quick-connect sealed helium test workpiece of this utility model is easy to install and operate and has high sealing performance, effectively solving the problem of leakage in the sealing performance test of water-cooled plate 4. It also solves the problem of the relatively complicated installation of traditional workpieces, reducing the difficulty and time of installation and increasing the sealing effect.
