Abstract

The invention relates to an air output flow guide cover, a flow mixing fan assembly and air conditioning equipment. The outer wall of the air output flow guide cover is a rotary face gradually contracting in the air output direction, and the outer wall of the air output flow guide cover comprises a first section, a second section and a third section which are sequentially distributed on the rotaryaxis of the rotary face in the air output direction. The outer wall of the air output flow guide cover is designed into a three-section type curved face with a meridian line including a line segment,an arca and a parabola. According to the Coanda effect, airflow can effectively adhere to the outer wall of the flow guide cover, the air output speed and distribution are reconfigured, and thereforegood air output flow guide performance is achieved, and vortex noise is effectively reduced. When the air output flow guide cover is applied to a flow mixing fan, the air output uniformity of the flow mixing fan can be effectively improved, and the surface air volume distribution requirement of a heat exchanger is met.

Description

technical field [0001] The present disclosure relates to the fan field, in particular to an air outlet guide cover, a mixed flow fan assembly and an air conditioner. Background technique [0002] The air duct system is one of the components used in the air conditioner to accelerate the heat exchange of the air in the air conditioner's operating area. In order to improve the quality and comfort of air-conditioning equipment, it is necessary to match suitable fans for different needs and models. [0003] In order to meet the air volume and pressure head indicators, the air path system of some air conditioners known to the inventor uses a mixed-flow fan. However, there is no wind or the air volume is too small near the fan motor shaft at the air outlet of the existing mixed flow fan, and the air volume distribution on the surface of the heat exchanger is uneven. Contents of the invention [0004] After research, it was found that the mixed-flow fan in the air-conditioning e...
