When the battery cells of energy storage batteries are in a low-temperature environment, the PTC heating components in the liquid cooling control unit are usually used to heat the cells to ensure that the cells can be charged and discharged within the appropriate temperature range.

[0003] The PTC heating element has a channel for the circulation of high-temperature media. Therefore, ensuring the sealing performance of the PTC heating element and preventing the leakage of high-temperature media is crucial to the life of the energy storage battery. The PTC heating element is usually sealed by glue filling, and then the airtightness of the PTC heating element is tested using an airtightness test tool.

[0004] The inflation port of the air tightness detection tool in the existing technology is difficult to adapt to the plug in the PTC heating component, which makes it difficult for the high-pressure gas in the inflation device to enter the PTC heating component, increasing the risk of high-pressure gas leakage, reducing the accuracy and work efficiency of the test, and increasing costs.

[0005] Therefore, it is urgent to design an airtightness detection tool for glue-filling sealing devices to solve the above technical problems. Utility Model Content

[0016] As an optional technical solution for an airtightness detection tool for a glue-filling sealing device, the air inlet and the air outlet are respectively located on two opposite end surfaces of the transition box.

Furthermore, it can also ensure that during the air tightness test, the PTC heating component is in a stable and controllable environment, reducing the influence of external environmental factors and improving the stability and reliability of the air tightness test.

[0037] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0038] This embodiment provides an airtightness detection tool for a glue-filling sealing device, which can reduce high-pressure gas leakage, improve the accuracy and work efficiency of airtightness testing, and achieve the purpose of cost saving.

[0039] like Figure 1-Figure 2 As shown, the airtightness testing tool for glue potting and sealing devices mainly includes an inflation detection component 100, a transition box 200, and a connecting air pipe 300. The inflation detection component 100 is filled with high-pressure gas, and the transition box 200 has an air inlet 210 and an air outlet 220. One end of the connecting air pipe 300 is connected to the inflation detection component 100, and the other end of the connecting air pipe 300 is connected to the air inlet 210, so that high-pressure gas enters the transition box 200 through the connecting air pipe 300. The air outlet 220 is configured to be plugged into the high-voltage plug 13 of the PTC heating component 10.

[0040] Based on the above design, in this embodiment, the arrangement of the inflation detection assembly 100, the transition box 200, and the connecting air pipe 300 allows the high-pressure gas within the inflation detection assembly 100 to pass through the connecting air pipe 300 and enter the transition box 200. The gas outlet 220 on the transition box 200 can be plugged into and matched with the high-voltage plug 13 of the PTC heating assembly 10, thereby allowing the high-pressure gas within the transition box 200 to be discharged from the gas outlet 220 into the PTC heating assembly 10. Within a certain period of time, if the high-pressure gas leakage value within the inflation detection assembly 100 is within a set range, it indicates that the air tightness of the PTC heating assembly 10 meets the standard.

[0041] The provision of the transition box 200 not only solves the problem in the prior art that the air-tightness detection tooling is difficult to adapt to the plug in the PTC heating component 10, but also makes the connection between the air-tightness detection component 100 and the PTC heating component 10 tighter and more adaptable, reduces the occurrence of high-pressure gas leakage, and improves work efficiency. At the same time, the transition box 200 can also play a role in stabilizing the pressure. During the inflation detection process, the pressure inside the PTC heating component 10 may be unstable due to the flow and pressure changes of the high-pressure gas. In this embodiment, by providing the transition box 200, the speed of the high-pressure gas flow can be slowed down and the amplitude of the pressure fluctuation can be reduced, thereby making the pressure inside the PTC heating component 10 more stable, which is conducive to accurate air-tightness detection and improving the accuracy of the detection. Furthermore, it can also ensure that during the air-tightness detection process, the PTC heating component 10 is in a stable and controllable environment, reducing the influence of external environmental factors and improving the stability and reliability of the air-tightness test. Furthermore, the PTC heating assembly 10 may be subject to impact and friction from the high-pressure gas during testing, and the provision of the transition box 200 can provide a certain degree of buffering and protection. This can reduce the direct impact and friction of the high-pressure gas on the PTC heating assembly 10, lowering the risk of damage to the PTC heating assembly 10, thereby extending the service life of the PTC heating assembly 10 and achieving cost savings.

[0042] It should be noted that if Figure 2 As shown, the PTC heating component 10 in this embodiment includes a main body 11, a high-voltage wiring harness 12, and a high-voltage plug 13. One end of the high-voltage wiring harness 12 is connected to the main body 11, and the other end is connected to the high-voltage plug 13. A plurality of wires 121 are provided in the high-voltage wiring harness 12, and the outer circumference of the wires 121 is wrapped with an insulating sleeve 122. There is a gap between the insulating sleeve 122 and the wires 121. The high-pressure gas in the transition box 200 passes through the high-voltage plug 13 and flows through the gap between the insulating sleeve 122 and the wires 121, and then flows into the main body 11 of the PTC heating component 10, thereby realizing the airtightness detection experiment of the PTC heating component 10.

[0043] Optionally, the high-voltage plug 13 in this embodiment can be set to an Amphenol plug commonly available on the market.

[0044] The inflation detection assembly 100 in this embodiment is a conventional component in the art, and therefore, its working principle and specific structure are not described in detail here.

[0045] like Figure 1 As shown, in this embodiment, the airtightness testing tool for the glue potting and sealing device further includes an inflation plug 400. One end of the inflation plug 400 is connected to the end of the connecting air pipe 300 away from the inflation detection assembly 100, and the other end of the inflation plug 400 is connected to the air inlet 210. The provision of the inflation plug 400 can improve the convenience of plugging the connecting air pipe 300 into the air inlet 210 connected to the transition box 200, while reducing the risk of gas leakage.

[0046] Furthermore, the inflation plug 400 and the connecting air pipe 300 in this embodiment are integrally formed, which simplifies the installation steps of the two, improves work efficiency, improves the air tightness between the inflation plug 400 and the connecting air pipe 300, and avoids leakage of high-pressure gas.

[0047] like Figure 1 As shown, the inflation plug 400 in this embodiment includes a main body portion 410 and a plug-in portion 420 that are interconnected. The end of the main body portion 410 away from the plug-in portion 420 is connected to the connecting air pipe 300, and the end of the main body portion 410 close to the plug-in portion 420 abuts against the end surface of the transition box 200; the plug-in portion 420 passes through the air inlet 210 and is placed inside the transition box 200.

[0048] Preferably, the main body 410 and the plug portion 420 in this embodiment are integrally formed. The provision of the main body 410 facilitates the operator to conveniently plug the inflatable plug 400 into the air inlet 210, thereby improving work efficiency. The provision of the plug portion 420 can improve the stability of the inflatable plug 400 during insertion and reduce the risk of the inflatable plug 400 becoming loose or falling.

[0049] like Figure 1 As shown, in this embodiment, the air inlet 210 and the air outlet 220 are respectively located on two opposite end surfaces of the transition box 200. When the air inlet 210 and the air outlet 220 are respectively located on two opposite end surfaces of the transition box 200, the path of the airflow in the transition box 200 becomes clear and direct, which helps to reduce turbulence and eddy currents of the airflow in the transition box 200, thereby improving the accuracy and efficiency of air tightness testing.

[0050] Furthermore, along the height of the transition box 200, the air inlet 210 is higher than the air outlet 220. This allows the high-pressure gas to naturally sink and diffuse within the transition box 200 by utilizing gravity. This helps the high-pressure gas more fully contact the inner wall of the transition box 200, thereby improving the accuracy of the airtightness test.

[0051] like Figure 1 As shown, the airtightness detection tooling for the glue-filling sealing device in this embodiment also includes a connecting piece 230 and a fixing piece (not shown in the figure). The connecting piece 230 is connected to the transition box 200, and a mounting hole 240 is provided on the connecting piece 230. The fixing piece is passed through the mounting hole 240 and connected to the working platform, thereby enabling the transition box 200 to be installed and fixed, avoiding vibration or shaking of the transition box 200, and improving the accuracy of airtightness detection.

[0052] Optionally, in this embodiment, there are multiple connecting members 230 and fixing members, and each connecting member 230 is provided with at least one mounting hole 240. The mounting holes 240 are arranged in a one-to-one correspondence with the fixing members, thereby reducing the stress concentration phenomenon of the transition box 200, improving its stability and reliability, protecting the transition box 200, and saving costs.

[0053] Optionally, the fixing member in this embodiment can be configured as a bolt, the connecting member 230 can be configured as a lifting lug, and the connecting member 230 is welded to the transition box 200 .

[0054] Optionally, the pressure resistance of the transition box 200 in this embodiment is not less than 35KPa, and the transition box 200 is a metal part. For example, the pressure resistance of the transition box 200 can be set to 40KPa, and the transition box 200 is made of stainless steel, thereby improving the safety performance of the airtightness detection tooling for the glue filling and sealing device.

[0055] Optionally, the airtightness detection tool for the glue potting sealing device in this embodiment can be used not only to detect the airtightness of the PTC heating component 10, but also to detect other products that use glue potting for sealing, thereby improving flexibility and applicability and saving costs.

[0056] Obviously, the above are only preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the scope of the present invention. The scope of the present invention is determined by the scope of the appended claims.
