Abstract:
A heat transfer loop system includes a primary passive two-phase flow segment with an evaporator, a condenser and a liquid reservoir, and a secondary actively pumped liquid flow segment in which the liquid in the reservoir is drawn by a liquid pump into the evaporator, where a portion of the liquid is vaporized by the heat input and moves into the primary segment while the excess liquid is pumped back to the reservoir. The evaporator consists of a porous wick and one or more liquid arteries encased in the porous wick. The liquid arteries have porous walls to allow liquid phase working fluid to flow into the surrounding porous wick. The liquid arteries have porous walls to allow liquid phase working fluid to flow into the surrounding porous wick. The excess liquid continues to move through the arteries and eventually out of the evaporator and into the reservoir. The porous wick provides sufficient capillary force to separate the liquid inside the arteries and the vapor in the evaporator.
