A drainage member 150 for mounting onto an evaporator having a base 114, tube members 112 and corrugated or convoluted fins located between the tube members, the drainage member comprising a first set of projections 154 which in use are in contact with convolutions 104 of the fins. Each of the first projections is preferably received in a gap 198 between the lowermost fin convolutions and the evaporator base, and has a first extending portion (156, fig. 7) in contact with the lowermost convolution of a fin and a second extending portion (158, fig. 7) in contact with the evaporator base. The drainage member may be secured to the evaporator by a spring force urging the two portions apart. Tabs (196, fig. 7) provided on the first projections may further improve retention of the drainage member. The drainage member may also have a second set of projections 164 which are in contact with the tube members 112 and/or end faces 190 of the fins. The first and second projections are preferably arranged in an alternating pattern along an elongate comb base 152. The invention is mainly applied to evaporators of vehicle air conditioning systems to facilitate removal of condensate.
