Against the backdrop of global climate warming and an increasingly severe energy crisis, new energy vehicles, as representatives of green transportation, have gradually become the backbone of the automotive industry. However, the widespread adoption of new energy vehicles is not without challenges, one of the most critical being how to ensure their safety and quality. In this context, helium leak detectors, with their high-precision leak detection capabilities, have become an indispensable part of the manufacturing process for new energy vehicles.

The Principle of Helium Leak Detector

The helium leak detector, also known as the helium mass spectrometer leak detector, operates primarily based on mass spectrometry technology and the unique physical properties of helium gas.

Firstly, helium is an inert gas with a small molecular weight, easy diffusion, and non-flammable characteristics, enabling it to easily penetrate tiny leak points. When helium is injected into the interior of an object to be tested, if there are leak points, helium gas will escape from these points and enter the surrounding environment.

Next, the helium leak detector utilizes mass spectrometry technology to detect the presence of helium in the surrounding environment. In a mass spectrometer, gas molecules are ionized into ions and separated and detected through the action of electric and magnetic fields. Since ions of different masses deflect to varying degrees in electric and magnetic fields, different gas molecules can be distinguished based on their masses. The mass spectrometer in the helium leak detector is specifically designed to detect helium molecules, determining whether helium is present in the surrounding environment.

Finally, if helium is detected in the surrounding environment, it indicates that the object under test has a leak point. Further analysis and localization can then be performed to determine the exact location and size of the leak.

The Importance of Helium Leak Detectors in the Manufacturing of New Energy Vehicles

The battery is the "heart" of a new energy vehicle, and its sealing performance is directly related to the safety and reliability of the vehicle. Even the slightest leak can lead to severe consequences, such as decreased battery performance, short circuits, and even the risk of fire. Helium leak detectors are capable of detecting these potential leak points with extreme precision, ensuring that battery packs maintain excellent sealing status and providing solid safeguards for the safe operation of new energy vehicles.

During the manufacturing process of new energy vehicles, various pipes, valves, and other components also require stringent sealing. Helium leak detectors can precisely test these areas, guaranteeing the overall system's good airtightness, thus enabling the stable performance of the vehicle's various functions.

Improving Product Quality: Through the detection of helium leak detectors, potential leaks in critical components of new energy vehicles can be promptly discovered and repaired, enhancing the overall quality of the product.

Ensuring Driving Safety: The application of helium leak detectors ensures the sealing performance of critical components in new energy vehicles, preventing safety accidents caused by leaks and safeguarding passengers' driving safety.

Meeting Regulatory Requirements: With the rapid development of the new energy vehicle market, countries have increasingly stringent requirements for the safety and reliability of new energy vehicles. Helium leak detectors can meet the relevant regulations' requirements for leak detection in new energy vehicles, helping manufacturers successfully pass product certification.

Reducing Maintenance Costs: Through the detection of helium leak detectors, leaks can be identified and repaired before the product leaves the factory, preventing leakage failures during use and thereby reducing maintenance costs.
