Abstract
A heat exchanger system, in particular a vacuum spray boiler, cools a hot fluid by spraying a coolant onto chambers carrying the hot fluid. This process may be performed in i) a vacuum, as in space, ii) atmospheric pressure, as on a launch pad of a space vehicle, or iii) any pressure therebetween. The heat exchanger system may incorporate a plate-fin heat exchanger. A coolant spray apparatus, used for spraying the coolant, and the heat exchanger are integrated within a vacuum chamber. The coolant, subsequent to changing to a vapor state after being sprayed onto the heat exchanger, may be exhausted to outside the system.
