Outdoor unit of air conditioner

Abstract

The invention discloses an outdoor unit of an air conditioner, which comprises a shell (4). An outdoor heat exchanger (2) and an outdoor fan (7) are arranged in the shell (4); a fan cover (10) covers on the outside of the outdoor fan (7); and the rear end face of the fan cover (10) is open and is connected with the outdoor heat exchanger (2). The outdoor unit of the conditioner can ensure that air blown by the outdoor fan uniformly exchanges heat with the outdoor heat exchanger, the heat exchange efficiency of the outdoor heat exchanger is greatly improved, the unnecessary electric energy waste is avoided, the use cost of the air conditioner is reduced, the credibility of the air conditioner is improved, the use experience of air conditioner users for the air conditioner is enhanced, and the air conditioner has good market application prospect. Besides, on the basis that the heat exchange efficiency of the outdoor heat exchanger is greatly improved, the outdoor heat exchanger is ensured to have good heat exchange effect, and the dimension of the outdoor heat exchanger is reduced, so the production cost of the air conditioner is reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an outdoor unit of an air conditioner. Background technique [0002] An air conditioner is an electrical device that regulates and maintains the indoor temperature at the condition required by the user. The air conditioning function of the air conditioner is completed by the refrigeration circulation system and the air circulation system. The refrigerant circulating in the refrigeration system exchanges heat with the air flowing in the room to achieve indoor cooling or heating, and provide people with fresh and comfortable air. indoor air environment. [0003] The refrigerating cycle system of the air conditioner includes a heat exchanger, a compressor and throttling devices. The air circulation system includes a fan and a fan motor, an air inlet and outlet and an air filter. The operation of the refrigeration cycle system and the air cycle system of the air condition...

AI Technical Summary

Problems solved by technology

[0007] However, when the outdoor fan 7 is running, the air volume distribution near the outdoor fan 7 is uneven, that is, the air volume at the back of the outdoor fan 7 is relatively weak, while the air volume around the outdoor fan 7 is relatively strong, which will cause the air blown by the outdoor fan 7 to Unable to perform uniform heat exchange on the outdoor heat exchanger 2, resulting in uneven heat exchange of the outdoor heat exchanger 2, seriously affecting the heat exchange efficiency of the outdoor heat exchanger 2, causing unnecessary waste of electric energy, and increasing the use cost of the air conditioner , which reduces the air conditioner user's experience of using the air conditioner
