The basic principle of helium detection for water-cooled panels
- Injection of helium: Inject helium into the equipment or system being tested, usually using a helium inflation system for control and monitoring.
- water-cooled panels: water-cooled panels are placed around the equipment or system to be inspected. The water-cooled panels have a heat dissipation function and control the temperature and propagation of the helium.
- Detection probe: A helium detection probe is mounted on the water-cooled plate, usually using cold-trap technology, where the helium gas is cooled and collected.
- Helium Detection Instrument: A device connected to the helium detection probe to detect and measure the adsorbed helium.
Advantages of helium detection of water-cooled panels
- High sensitivity: Water-cooled panel helium detection technology is very sensitive to hydrogen leaks and can detect small leaks.
- Fast: Water-cooled plate helium detection technology responds quickly to hydrogen leaks and can detect leaks in a short period of time.
- Non-Invasive: Water-cooled panel helium detection is a non-invasive method that does not affect the equipment or system being tested.
- Intuitive: Water-cooled panel helium detection technology visualizes the extent of a hydrogen leak by displaying the helium concentration.
