Abstract

A combined type evaporator for an automotive air conditioner belongs to accessories of automotive air conditioners. The combined type evaporator for the automotive air conditioner is formed by assembling a concurrent flow evaporator core body, a tubular sheet type evaporator core body and a connector, wherein one end of the connector is welded and communicated with the other end of a refrigerant outlet pipe while the other end of the connector is welded and communicated with a third end of a refrigerant inlet pipe; a distance t between a fin air outlet end face and a hydrophilic fin air inlet end face is not greater than 1 mm; the combined type evaporator for the automotive air conditioner can enable condensed water flowing out of the concurrent flow evaporator core body to transitionally flow to the tubular sheet type evaporator core body so as to be discharged out of the evaporator smoothly. Therefore, the evaporator not only can realize the requirements on refrigerating capacity needed by an air conditioning system, but also can discharge the condensed water smoothly when a certain installation space is guaranteed.
