Abstract
A heat exchanger includes a collecting pipe, a number of heat exchange tubes and a distribution pipe. A pipe wall of the distribution pipe defines a number of through holes communicating with the collecting pipe. The through holes are a first through hole, . . . an (n−1)through hole and an nthrough hole disposed in sequence along a direction from a first end to a second end of the distribution pipe. A distance between an (i+1)through hole and an ithrough hole is: d=αL, i=1, 2, . . . n−1, α=0.618, Lis a distance between adjacent heat exchange tubes. As a result, uniformity of refrigerant distribution in the heat exchanger is improved.
