Vortex parallel flow countercurrent evaporator for automotive air conditioner

The invention relates to a vortex parallel flow countercurrent evaporator for an automotive air conditioner, which comprises a plurality of vortex type flat tubes, wherein the vortex type flat tubes are arranged in parallel, extended to form a vortex shape and separated by fins; refrigerant runners are formed in cavities of the vortex type flat tubes; the adjacent vortex layers of individual vortex type flat tubes are in sealing connection by the fins on two sides to form secondary refrigerant runners exchanging heat with refrigerants; inlets and outlets of each refrigerant runner are communicated with one another respectively; the inlets and outlets of each secondary refrigerant runner are communicated with one another respectively; and the refrigerants in the refrigerant runners and secondary refrigerants in the secondary refrigerant runners flow reversely. The vortex parallel flow countercurrent evaporator for the automotive air conditioner has a simple structure, occupies a small area, is difficult to deform by stress, vibration, thermal expansion and the like under severe conditions to influence the sections of the runners, makes smooth the circulation of the refrigerant, remarkably increases the travel of the refrigerant, improves the refrigeration efficiency and greatly reduces machining difficulties.
