vapor chambers

A vapor Chamber is a planer heat pipe, which can spread heat in two dimensions. They are typically used in high heat flux applications, or when two-dimensional spreading is required. Vapor Chamber technology enables higher CPUs with a higher TDP (or overclocked state) to be efficiently and effectively cooled to safe operating temperatures, extending component and product life. As shown in the diagram, vapor chamber features a wick design that filled with coolant. When heated, the coolant changes phase from a liquid to a gas and back again to transfer heat​
