What is a phase-change plate used for?

A phase-change plate absorbs transient peak heat from electronics using the latent heat of a phase-change material sealed inside a metal cavity. It suppresses temperature spikes and stabilizes operating temperature in military electronic cabinets, airborne radar, aerospace payloads, high-power industrial power electronics and laser equipment.

Can the phase-change temperature be customized?

Yes. We offer low temperature range 3-25 °C, medium temperature range 26-55 °C and high temperature range 56-120 °C. Metallic PCM such as gallium and indium alloys, non-metallic PCM such as n-Hexadecane, n-Octadecane and aerospace special wax, and other optional PCM including alkanes and inorganic salts are available.

How is the phase-change plate sealed?

The plate uses an integrated vacuum brazed sealing structure. After brazing, every unit goes through airtightness and pressure testing, drying, and helium mass spectrometry leak testing under both positive and negative pressure to guarantee long-term airtight performance.
