(54) | Thermal management system |
(57) A system (100) includes a primary evaporator (115) facilitating heat transfer by
evaporating liquid to obtain vapor. The primary evaporator (115) receives the liquid
from a liquid line (125) and outputs the vapor to a vapor line (130). The primary
evaporator (115) also outputs excess liquid received from the liquid line to an excess
fluid line. A condensing system (120) receives the vapor from the vapor line (120),
and outputs the liquid and excess liquid to the liquid line (125). The excess liquid
is obtained at least partially from a reservoir (147). A primary loop (105) includes
the condensing system (120), the primary evaporator (115), the liquid line (125),
and the vapor line (130), and provides a heat transfer path. Similarly, a secondary
loop (110) includes the condensing system (122), the secondary evaporator (150), the
liquid line (160), the vapor line (130), 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.
