What Is a Vapor Chamber?
First things first, to learn about the vapor chamber manufacturing process, you need to know how this product is structured.
A vapor chamber is a planar heat transfer device that employs liquid-vapor phase change to transfer heat.
It contains:
- Copper cover plates
- Wick structure
- Working fluid
- Internal vapor space
The operating principle is simple:
- Heat enters the evaporation area.
- The working fluid absorbs heat.
- Liquid changes into vapor.
- Vapor spreads through the chamber.
- The vapor goes on to provide heat at cooler areas.
- Liquid returns through the wick.
As such, vapor chambers can effectively spread heat without the need for mechanical movement.
Why does it make a difference for vapor chamber manufacturing process
Vapor chamber is a performance dependent on manufacturing quality.
This can be impacted by a small production error:
- Thermal resistance
- Heat transfer speed
- Reliability
