Vapor Chamber

Category:

Description

Vapor chambers are easily integrated into thermal solutions and can offer thermal performance improvements on the order of 10% to 30% over copper and heat pipe based solutions and can often be lighter in weight than equivalent extruded or copper based heat sink. These improvements allow for designers to design for higher ambient or lower noise due to low required fan speeds. 

A vapor chamber basically is like a planar heat pipe, which can spread heat in multi dimensions.  They are typically used when heat density is very high and high powers are subjected to a small area.
