Abstract
A heat transfer system includes a first loop and a second loop. The first loop includes a condenser having a vapor inlet and a liquid outlet, a vapor line in fluid communication with the vapor inlet of the condenser, a liquid line in fluid communication with the liquid outlet of the condenser, and primary evaporators fluidly coupled in series with the liquid line and in parallel with the vapor line. The second loop includes a reservoir, a secondary evaporator having a vapor outlet coupled to the vapor line and a fluid inlet coupled to the reservoir, and a sweepage line in fluid communication with the reservoir and the primary evaporators.

20. A heat transfer system comprising a secondary system comprising:
-
an evaporator including; an outer enclosure; a vapor outlet fluidly coupled through the outer enclosure; a wick within the outer enclosure and fluidly coupled to the vapor outlet; and a porous structure contacting a surface of the wick and the outer enclosure; and a reservoir including a reservoir casing, and a tube within the reservoir casing that defines a channel that is fluidly coupled to the porous structure of the evaporator; wherein the porous structure is positioned between the tube and the wick and thermally isolates the surface of the wick from the tube. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
