Title:
EVAPORATOR
Document Type and Number:
Japanese Patent JP2014059103
Kind Code:
A
Abstract:

To provide an evaporator that can suppress a rapid temperature rise of air blown out into a cabin when a compressor is turned off.

An evaporator includes a plurality of pipe sets 14 each comprising two flat refrigerant flow pipes 13 that are disposed at an interval in a ventilation direction. The plurality of pipe sets 14 are disposed in parallel at intervals in the thickness directions of the refrigerant flow pipes 13, and ventilation gaps 15 are formed between the pipe sets 14 adjacent to each other. Corrugated fins 16 are arranged astride both of the refrigerant flow pipes 13 of the pipe sets 14. A plurality of louvers 20 are formed in connection parts 16a of the corrugated fins 16 to be juxtaposed in the ventilation direction. Length of the plurality of louvers 20 that are located on downwind edge sides of the upwind refrigerant flow pipes 13 and on upwind edge sides of the downwind refrigerant flow pipes 13 is made shorter than that of the louvers 20 that are located on the most upwind sides of the upwind refrigerant flow pipes 13 and on the most downwind sides of the downwind refrigerant flow pipes 13.
