Abstract

A wick for use in a heat pipe is provided incorporating particles of micro-encapsulated phase change material bonded together to form the wick. Use of a wick structure comprising micro-encapsulated PCM particles has the advantage of providing an additional heat absorber. This greatly enhances the ability of the heat pipe to absorb excess heat and may help to prevent damage to the heat pipe or heat generating component, such as an electronic device, especially at times of peak thermal loads.
