Abstract

The invention discloses a fan of an outdoor unit of an air conditioner, which comprises a motor bracket, a motor component consisting of a motor and axial-flow fan blades, a fan guide and a top cover plate provided with a wind outlet part, wherein the motor component and the fan guide are arranged under the top cover plate through the motor bracket; and the fan guide is provided with a horn-shaped expanded opening formed by a turn-up. The fan of the outdoor unit of the air conditioner has the advantages that: the design is in accordance with air flow dynamics; the air flow resistance is reduced effectively; the performance of the fan is improved; and the noise is reduced.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner outdoor fan. Background technique [0002] The working principle of the air conditioner is that the indoor unit absorbs the heat in the room, and through the compression or expansion of the refrigerant, the heat is transferred to the outdoor unit for discharge. As an integral part of the air conditioner, the outdoor unit of the air conditioner plays an important role. [0003] At present, the air guide rings of the existing air-conditioning outdoor unit fans on the market are generally installed under the top cover, and the air guide rings used are cylindrical. Since the cylindrical air guide pattern does not conform to aerodynamics, not only The air supply efficiency is low, and the noise emitted is relatively high. Contents of the invention [0004] In view of the above-mentioned defects, the technical problem to be solved by the present invention is to pr...
