Abstract

PURPOSE: To improve the heat exchange efficiency of the condenser by providing partition plates in the inner parts of headers and partitioning a coolant passage constituted of tubes into at least tow or more passage groups and causing a coolant to meander at least once or more and thus to circulate.

CONSTITUTION: A coolant flowing in the condenser via a upper inlet pipe 6 of a lefthand header 3 passes respective tubes 1 of an inlet side passage group A and reaches a righthand header 4. Thereafter, the coolant is reversed and flows into a lefthand header 3 via respective passages of an intermediate passage group B, and further is reversed and flows into a righthand header via respective passages of an outlet side passage group C and flows out of the condenser via an outlet pipe 8. While circulating among respective passage groups, the coolant is heat exchanged with air circulating in the direction W within air circulating gaps including corrugated fins 2 formed between tubes 1 and 1. Partition plates 10 and 11 are provided at a position slightly upper than the central part of the lefthand header 3 and at a position approximately 1/3 of the full length from the lower end of the righthand heater 4.
