HEAT EXCHANGER

摘要

A heat exchanger including a plurality of tubes disposed horizontally, a pair of vertical headers connecting the tubes, and at least one flow distribution baffle mounted to a header at one group of the plurality of tubes such that the flow distribution baffle is positioned between tubes of the one group. Each of the at least one flow distribution baffle is provided with at least one distribution hole allowing a refrigerant to pass therethrough. The heat exchanger prevents unbalanced distribution of the refrigerant when it operates as an evaporator of an outdoor unit.

1. A heat exchanger comprising:
a plurality of tubes disposed horizontally, each having first and second ends; a first header disposed to communicate with the first end of each of the tubes; a second header disposed to communicate with the second end of each of the tubes; at least one flow passage defining baffle mounted to at least one header of the first header and the second header to prevent flow of the refrigerant in the at least one header in a longitudinal direction and to divide the tubes into n (n≧2, where n is an even number) groups, each of the groups having tubes allowing the refrigerant to flow in one direction therethrough and the number of the at least one flow passage defining baffle being n−1; and at least one flow distribution baffle mounted to at least one header of the first header and the second header and arranged at one group of the n groups such that the flow distribution baffle is positioned between the tubes belonging to the one group, each of the at least one flow distribution baffle being provided with at least one distribution hole allowing the refrigerant to pass therethrough.
