Abstract

An evaporator capable of improving heat-exchange efficiency by enhancing performance to distribute refrigerant to many refrigerant passages of a refrigerant distribution pipe from a throttle. The evaporator is capable of suppressing the occurrence of a refrigerant passing noise by the throttle while maintaining the throttle of a nozzle at a certain size as to be able to function as a throttle. The inner diameter of the throttle in the nozzle is made as large as possible. The cross-sectional center of the throttle of the nozzle is off-centered toward the upper side relative to the cross-sectional center of the refrigerant distribution pipe inserted into the inlet tank of the evaporator. The refrigerant flows out of the throttle in a mixed condition of liquid and gas, and separation of gas and liquid in the refrigerant is alleviated inside the refrigerant distribution chamber. The refrigerant flowing out of the throttle of the nozzle can easily flow into the upper side of the refrigerant distribution pipe rather than the lower side. Thus, the performance of refrigerant distribution from the throttle to many refrigerant passages of the refrigerant distribution pipe is improved.
