Abstract

The invention relates to the technical field of motors. The invention discloses a motor fan cover capable of improving ventilation cooling efficiency. The motor fan cover comprises an air hood middleshell, a top ventilation groove is fixedly formed in the top of the air hood middle shell, first filter screens are fixedly installed on the inner sides of the bottom of the air hood middle shell, bottom supports are fixedly installed on the inner sides of the two first filter screens, and a main filter screen is fixedly installed between the two bottom supports. The air flow speed between the topbaffle and the top gap of the middle shell of the fan cover is increased, so that the pressure intensity between the top baffle and the middle shell of the fan cover is reduced, the pressure intensity at the top ventilation groove is reduced; and the pressure intensity at the bottom of the top ventilation groove is greater than that at the bottom of the top ventilation groove, so that the airflowat the bottom of the top ventilation groove can be sucked out through the top ventilation groove, the flowing of the air in the middle shell of the fan cover is accelerated in the process, and the effect of improving the ventilation cooling efficiency of the motor fan cover is achieved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor fan cover for improving ventilation and cooling efficiency. Background technique [0002] With the development needs of intensive society, the country has higher and higher requirements for energy saving and consumption reduction. For the motor industry, effective improvement of the motor heat dissipation structure can reduce the temperature of the motor working environment, thereby effectively reducing the power consumption of the motor. And for the loss of electric energy, the existing motor fan cover structure can only realize passive heat dissipation, and the heat dissipation and cooling efficiency is low, which is not conducive to the subsequent reduction of power consumption. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the invention provides a motor fan cover with improved ventilation and c...
