A heat exchanger (1) with a number of isolated cooling circuits; in particular a heat exchanger unit for an automobile, having a cooling circuit for operating as a condenser for an air conditioning system and a cooling circuit operating as a transmission oil cooler for vehicle transmission. The heat exchanger comprises two manifolds (4,16) which are connected to a heat exchanger core comprising a plurality of tubes (6-13), in which each manifold has a pair of baffles (14,15,17,18) positioned either side of a redundant tube (9), such that two isolated circuits are formed, and the redundant tube does not form part of either circuit. A hole (23,24) in the manifold wall between the pair of baffles enables leak testing to be performed. |
