Abstract

A compact, rugged and light weight condenser structure for a heat exchange system, preferably fabricated in layers and incorporating a jet fin structure for heat exchange with a single phase coolant fluid and tapered passages to maintain relatively constant vapor flow velocity and a consistent, high efficiency flow regime in a refrigerant fluid including vapor and liquid phases. Layered construction permits economical fabrication of the condenser in a plurality of configurations and heat exchange capacities. Tapered configuration of the refrigerant passages, together with the consistent distribution of jet fin heat exchange to the coolant allows a flow regime to be maintained which is highly tolerant of variation in the direction and force of acceleration forces on the condenser. Accordingly, a condenser capable of highly consistent heat exchange performance over a wide range of acceleration conditions is provided.
