Vapor Chamber
A Vapor Chamber consists of two flat metal plates enclosing a thin layer of liquid working fluid. When heat is applied, the liquid absorbs thermal energy and evaporates, forming a high-pressure vapor environment. Heat is then rapidly transferred through evaporation and condensation cycles. Vapor chambers utilize two-phase heat transfer (liquid–vapor) to efficiently spread heat from a concentrated heat source over a larger area. Advantages include lower thermal resistance、higher heat transfer efficiency、more uniform temperature distribution. They are particularly suitable for high-power, small-area heat sources where traditional heat pipes are insufficient.
