Power Batteries and Energy Storage Batteries
Industry Overview

In the production process of power batteries and energy storage batteries, the sealing quality in steps such as cell casing welding, cover plate sealing, and filling port sealing directly affects battery safety and cycle life. Different cell formats—prismatic, cylindrical, pouch, and blade—present varying leak risk points.

If sealing defects exist, electrolyte leakage can lead to battery scrap in minor cases, or cause serious safety incidents such as thermal runaway. NOY provides a full-process helium mass spectrometer leak detection solution covering pre-filling, post-welding, and post-sealing stages, intercepting defective products before electrolyte filling to avoid waste of costly materials. End-of-line (EOL) testing at the finished product stage completes the final sealing verification before batteries leave the factory.

Why Helium Mass Spectrometer Leak Detection?
High Sensitivity Helium leak testing can detect extremely low leak rates (on the order of 10⁻¹² Pa·m³/s ), sufficient to identify leak paths with micron- or even nanometer-scale apertures, offering significantly superior detection capability compared to water immersion and pressure decay methods.
Cycle Time Matching Vacuum chamber leak testing can adapt to the cycle time of large-scale production lines, meeting the demands of high-volume manufacturing.
Traceable Data Test data is automatically recorded, enabling full traceability of product quality throughout the entire process.

Helium Mass Spectrometer Leak Detection for Consumer Batteries

High-sensitivity, fast-response leak detection solutions. Customizable testing fixtures and detection units are available for different battery models, facilitating easy integration into existing production lines.

Industry Overview

Batteries used in consumer electronic products are characterized by small size, high volume, and fast production line cycle times, with stringent requirements for sealing consistency. The sealing welds of coin cells, the edge seals and terminals of pouch cells, and the casings and cover plates of prismatic cells are all high-risk areas for leakage.

A single battery with sealing defects that reaches the market can cause safety incidents and directly impact brand reputation. NOY provides high-sensitivity, fast-response leak detection solutions, with customizable testing fixtures and detection units available for different battery models, facilitating easy integration into existing production lines.

Helium Mass Spectrometer Leak Detection for Liquid Cooling Systems

From cold plate micro-channel leak detection to end-of-line (EOL) testing for complete system loops, ensuring sealing reliability throughout the entire cooling system.

Liquid Cooling Systems
Industry Overview

As computing density in data centers continues to rise, air cooling is no longer sufficient to meet the cooling demands of high-heat-flux applications. Liquid cooling technology has become the mainstream thermal management solution for high-performance computing equipment such as AI servers.

Components such as cold plates, cooling tubes, quick-connect couplings, manifolds, and coolant distribution units (CDUs) operate in closed cooling circuits over extended periods. Even the smallest leak can allow coolant to penetrate electronic components, causing equipment damage or even data center downtime. Leak detection covers three levels: individual components, assembled units, and complete system loops. NOY provides helium mass spectrometer leak detection equipment tailored to each type of test object.

Helium Mass Spectrometer Leak Detection for Power Equipment

Full coverage with both stationary and portable leak detection equipment — vacuum chamber batch testing in production, and on-site portable testing in the field.

Industry Overview

The rapid expansion of AI computing power has driven continued growth in data center electricity demand, ushering in a period of large-scale construction and upgrades for power infrastructure. From high-voltage distribution cabinets and uninterruptible power supply (UPS) equipment within data centers, to gas-insulated switchgear (GIS) and transformers on the grid side, the sealing reliability of various power equipment is directly linked to power supply safety.

Distribution cabinets must meet IP rating requirements. Once SF₆ gas in GIS leaks, it not only compromises insulation performance but also violates environmental regulations. NOY provides both stationary and portable leak detection equipment: vacuum chambers and specialized leak testing machines for batch testing in production, and portable leak detectors for on-site testing in the field.
