Claims

[Scope of utility model registration request]

A first tank section 11 into which the refrigerant from the compressor 1 is introduced, and a number of flat tubes 15 through which the refrigerant flows from the first tank section 11 so as to flow parallel to each other.
and heat transfer fins 9 provided between the flat tubes.
and a second tank portion 12 provided at the outlet end of the flat tube.
Reference numeral 5 refers to a refrigerant throttle valve part which is arranged so that when the refrigerant flowing therein flows out from the flat tube 15, it faces at least vertically downward, and which is provided in the lower end area of the second tank part 12 and in the cooling cycle. An air conditioner for an automobile, characterized in that the air conditioner 4 is directly connected to the air conditioner 4 through a conduit 6a as thin as possible.
