Abstract (en)

A duplex heat exchanger comprises unit heat exchangers (A, B) which have a plurality of tubes (1, 21) arranged parallel with each other and comprise fins (2, 22) each interposed between two adjacent ones of such tubes, opposite ends of each tube being connected to a pair of headers (3, 4 and 23, 24) in fluid connection therewith. The unit heat exchangers are closely juxtaposed to each other fore and aft in a direction of air flow. Coolant circuits of the unit heat exchangers are connected either in series or in parallel with each other.
