Claims

[Scope of utility model registration request]

A refrigerant flow path 2 formed by bending and meandering a flat tube 1 in which a plurality of mutually parallel and independent branch paths are formed inside, and a corrugate disposed in contact between the bent and meandering facing surfaces of the tube 1. In a refrigerant evaporator equipped with fins 3 and a header communicating with the end of the flat tube 1, a section 5.7 on the tool for improving the position of condensation is formed in the evaporator in the direction of the air flow 4 to be cooled. and positioning the inlet header 6 of the downstreammost section 5 of the airflow 4 at the upstream end of the refrigerant flow path 2,
The rudder 6 to the inlet and the header 8 of the upstream section 7 are in a non-communicating state, and the rudder 9 to the outlet of the most downstream section 5 is made to communicate with the inlet header 10 of the upstream section 7. refrigerant evaporator.
