Abstract

A refrigerant distributor for a heat exchanger is disclosed. The distributor comprises: a pipe having an inlet disposed generally at one end of the pipe, refrigerant flowing into the pipe through the inlet. A cross-section of a flow passage within the pipe gradually decreases from the one end to the other end of the pipe. With the above configuration, the refrigerant can be distributed relatively uniformly.
