Surface condenser

Claim 1

IN A SURFACE CONDENSER, IN COMBINATION, MEANS FOR PRODUCING A DIRECTED CURRENT OF COOLANT; A SOURCE OF VAPOROUS MEDIUM WHOSE TEMPERATURE IS HIGHER THAN THE TEMPERATRE OF COOLANT SO THAT THE MEDIUM YIELDS CONDENSATE IN RESPONSE TO EXCHANGE OF HEAT WITH THE COOLANT; AND A CONDENSER UNIT INCLUDING A PAIR OF TUBULAR CONDUCTORS EACH HAVING AN INTAKE END CONNECTED WITH SAID SOURCE AND A CONDENSATE-DISCHARGING SECOND END, SAID CONDUCTORS BEING DISPOSED IN THE PATH OF AND SUBSTANTIALLY TRANSVERSELY TO THE DIRECTION OF THE FLOW OF COOLANT SO THAT COOLANT BRUSHING SAID CONDUCTORS TENDS TO FORM AROUND SAID CONDUCTORS A STAGNANT BOUNDARY LAYER WHICH HINDERS THE EXCHANGE OF HEAT BETWEEN THE MEDIUM AND THE FLOWING COOLANT, ONE OF SAID CONDUCTORS BEING LOCATED UPSTREAM OF THE OTHER CONDUCTOR AS SEEN IN THE DIRECTION OF FLOW OF THE COOLANT SO THAT COOLANT BRUSHING SAID ONE CONDUCTOR IS HEATED AND ITS COOLING CAPACITY DECREASES PRIOR TO BRUSHING SAID OTHER CONDUCTOR, SAID OTHER CONDUCTOR COMPRISING MEANS FOR REDUCING THE EFFECT OF THE BOUNDARY LAYER SUFFICIENTLY TO INSURE THAT THE HEAT EXCHANGING CAPACITY OF SAID OTHER CONDUCTOR IS SUPERIOR TO THE HEAT EXCHANGING CAPACITY OF SAID ONE CONDUCTOR PROPORTIONALLY WITH THE DROP IN COOLING CAPACITY OF THE COOLANT WHEREBY THE TEMPERATURE OF CONDENSATE AT BOTH SAID SECOND ENDS IS AT LEAST NEARLY THE SAME.
