Abstract
A heat exchanger for use as an evaporator in a motor vehicle air conditioning system comprises a multiplicity of plates stacked in pairs and defining within each pair a flow chamber for a first fluid. Between each pair of plates and the next is a flow passage for a second fluid. Each plate has a bent-back edge portion or plate foot which extends at right angles to the main part of the plate. Each plate foot abuts against a similar plate foot of an adjacent plate, while leaving an area free to define at least one drain passage through the bottom of the heat exchanger which is formed by the overlapping plate feet. Water condensing from the air passed through the evaporator is drained through these drain passages.
