Abstract

The invention discloses an outlet housing and an outdoor unit of an air conditioner. The outlet housing comprises an intermediate connecting plate, a plurality of fixing rings with different diameter,an outer frame fixing frame, a plurality of main air guide strips and a plurality of secondary air guide strips, wherein the outlet housing is divided into a first area which is close to the intermediate connecting plate, and a second area which is close to the outer frame fixing frame; each main air guide strip comprises a straight line section which is arranged at the first area, and a plurality of tangent arc sections which are arranged in the second area; each secondary air guide strip comprises circular arc sections which are staggered from the tangent arc sections; the circular arc sections are in the same bending direction with the circular arc sections. According to the outlet hosing, the straight line sections are arranged in the first area, and the second area is provided with the tangent arc sections and the circular arc sections, so that the air flowing capacity is improved; the loss of rotating kinetic energy is decreased; and the efficiency of an air blower is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air outlet cover and an air conditioner outdoor unit. Background technique [0002] At present, an axial flow fan is installed in the outdoor unit of the air conditioner, and the motor drives the impeller to rotate to form an outwardly blowing airflow. An air outlet cover is provided at the air outlet of the casing to prevent sundries and the like from entering the casing through the air outlet to ensure the safe use of the outdoor unit of the air conditioner. The traditional air outlet hood has large wind resistance, which affects the air outlet efficiency of the axial flow fan. [0003] Therefore, it is necessary to provide a novel air outlet cover to solve the above technical problems. Contents of the invention [0004] The main purpose of the present invention is to provide an air outlet hood, aiming to solve the problem of low efficiency of the axial flow fan...
