FGHP (Fine Grid Heat Pipe)
World's Highest-Performance Thin Vapor Chamber Fine Grid Heat Pipe (FGHP) is a specialized high-performance flat-plate heat piping used for heat diffusion.
FGHP Features
- The design's superior heat-diffusion performance evenly spreads ultra-high-density heat, thereby lowering the heat density for efficient radiation, making FGHP ideal for small, high-power FPGAs and GPUs, and high-power compound semiconductors such as GaN and SiC.

FGHP Cooling Circulation Mechanism
- ①Refrigerant evaporation…Heat received from the heat source causes the refrigerant to evaporate. Evaporation is further improved by the dimple structure of the heat-receiving component.
- ②Vapor movement…Evaporated vapors are diffused by the heat dissipation area along the vapor paths.
- ③Vapor condensation…The vapor condenses into a liquid in the heat dissipation area. Condensation is further improved by the dimple structure of the heat dissipation area.
- ④Condensation movement…The condensed refrigerant returns to the heat receiving area through the grooves on the wick and between the dimples.
