Abstract (en)

A reversible capillary pumped heat transfer loop for transferring heat between first and second locations (2,3) and comprising, at each location, a heat transfer unit (1) for evaporating a working fluid when the unit is required to remove heat and for condensing the working fluid when the unit is required to deliver heat, each such unit (1) including a capillary device (19,20) and one or more channels (10) associated with the capillary device for the collection of fluid from it when the unit is acting as an evaporator and for the feeding of fluid to it when the unit is acting as a condenser whereby each unit comprises a fluid reservoir (18) into which the capillary device extends, the combined volumes of the reservoirs and the amount of working fluid in the loop being selected to ensure that there is always sufficient liquid in the reservoir to keep the capillary devices saturated with liquid.
