Pool boiling heat transfer
WebCurrently, the two-phase cooling technique based on phase change pool boiling heat transfer has received a lot of attention because of its potential to fully utilize the latent heat of the fluid and produce a highly effective heat dissipation capacity while keeping the equipment's operating temperature within an acceptable range. WebNov 15, 2014 · Boiling Heat Transfer. 1. Boiling is a phenomenon that occurs at a solid-liquid interface when a liquid is brought in contact with a surface maintained at a temperature sufficiently above the saturation temperature of the liquid. As the heat is …
