OUTDOOR MACHINE FOR AIR CONDITIONER

摘要

PROBLEM TO BE SOLVED: To provide an outdoor machine for air conditioners for improving the wind velocity distribution of suction and discharge flow to a heat exchanger that especially affects the suction flow of a fan and to uniformize heat exchange efficiency and draft resistance to improve the efficiency of the fan corresponding to the request for saving energy and miniaturizing a body. SOLUTION: The diameter of a pipe is changed by a heat transfer pipe with a faster stage of wind velocity and that with a slower stage of wind velocity than the distribution of the wind velocity of air on the downstream of the heat exchanger being installed on the upstream of the fan, thus straightening the suction flow of the fan and changing the draft resistance of the heat exchanger for each step at a time.
