Thermal control layer in miniature LHP/CPL wicks

摘要

A LHP/CPL wick includes an unconsolidated wick portion positioned within a first consolidated wick portion and a second consolidated wick portion. This wick provides a large DELTAT across the wick, and sufficient capillary action for miniature LHP/CPL applications. Furthermore, the unconsolidated wick portion allows accommodation of mismatched coefficients of thermal expansion. A LHP/CPL having this wick is particularly applicable to silicon cooling devices.
