Patent ID: 8381805

Claim:
A heat transfer system comprising: a primary evaporator having a liquid inlet port, a vapor outlet port, and a fluid outlet port; a condenser coupled to the primary evaporator by a liquid line coupled to the liquid inlet port of the primary evaporator and a vapor line coupled to the vapor outlet port of the primary evaporator; a secondary evaporator connected to the primary evaporator through a sweepage line; and a reservoir system comprising: a reservoir coupled to the fluid outlet port of the primary evaporator through a sweepage line and positioned between the primary evaporator and the secondary evaporator, wherein the secondary evaporator is positioned between the reservoir and the condenser; a first flow directional device positioned between the fluid outlet port of the primary evaporator and the reservoir for restricting fluid from flowing into the reservoir from the primary evaporator; and a second flow directional device coupled to a liquid outlet port of the reservoir for restricting fluid from flowing out of the reservoir through the liquid outlet port of the reservoir.
