Abstract
The invention introduces a two part wick for use in the evaporator of a two phase loop (LHP/CPL). The primary wick controls evaporation from the primary heat input area. The secondary or “distribution” wick separates the liquid and vapor volumes of the evaporator and feeds liquid to the primary wick. The secondary wick allows the primary wick to be configured so heat enters from the liquid side of the wick, this constitutes a non-inverted meniscus evaporator which can tolerate high heat fluxes without restricting vapor flow. The secondary wick is removed from the primary heat flow path lends itself to fabrication in small dimensions compatible with direct cooling of electronic devices.
