ABSTRACT:
A refrigerant evaporator in a refrigerating cycle, especially in an automotive air conditioner of the type comprising a flat tube which is provided with refrigerant passages therein and formed to weave up and down, and a plurality of corrugated fin units each of which is interposed between the adjacent upright portions of the flat tube and fixed thereto so as to enhance heat exchange between refrigerant flowing within the flat tube and air flowing horizontally between the upright portions. In the evaporator of the above type, in order to prevent the water condensed over the surfaces of the flat tube and the corrugated fin units from being entrained by air into the compartment of the automobile, the portion of the flat tube on the downstream side of air flow is spaced apart from each corrugated fin unit to provide a non-contact space therebetween so as to force the condensed water to drop through the non-contact space.
