Vapor chamber heat sink

aluminumfor electronics

A Vapor Chamber is a planer heat pipe that comprises of: an evaporator (which makes contact with the area of heat input) a sealed vapor chamber containing a working fluid (see below) which transfers heat from the evaporator to the condenser a condenser where the transferred heat cools on the condenser surfaces Two-dimensional heat dissipation. Vapor Chambers are often confused with heatpipes, and while they share some similarities, they are quite different. Heat pipes remotely conduct the heat from one end to the other in a linear structure whereas vapor chambers evenly spread the dissipated heat. During the vapor chamber's operation, the 'heat source' transfers thermal energy to the evaporator side of the vapor chamber. This heat converts the (working) liquid in the sealed chamber into a 'vapor.' The vapor then cools, via the wicks, on the surfaces of the condenser where the heat will be removed by either convection cooling, forced air convection cooling or liquid cooling. Once the vapor cools to a liquid, it returns to the evaporator via capillary action and the cycle repeats continuously making the vapor chamber a highly efficient thermal management device.
