Abstract
A system includes a primary evaporator facilitating heat transfer by evaporating liquid to obtain vapor. The primary evaporator receives a liquid from a liquid line and outputs the vapor to a vapor line. The primary evaporator also outputs excess liquid received from the liquid line to an excess fluid line. A condensing system receives the vapor from the vapor line, and outputs the liquid and excess liquid to the liquid line. The excess liquid is obtained at least partially from a reservoir. A primary loop includes the condensing system, the primary evaporator, the liquid line, and the vapor line, and provides a heat transfer path. Similarly, a secondary loop includes the condensing system, the primary evaporator, the liquid line, the vapor line, and the excess fluid line. The secondary loop provides a venting path for removing undesired vapor within the liquid or excess liquid from the primary evaporator.
