Abstract

The invention provides an air conditioner, an outdoor unit thereof and an electrical appliance box of the outdoor unit. The electrical appliance box of the outdoor unit comprises a casing, a control main board, an air inlet and an air outlet. The casing comprises a first lateral wall and a second lateral wall. The control main board is arranged in the casing, and a gap is arranged between the control main board and the first lateral wall. The air inlet is arranged at the first end of the first lateral wall. The air outlet is arranged at the second end of the first lateral wall and comprises a first side and a second side, the first side of the air outlet convexly extends towards the interior of the electrical appliance box to be provided with a first bending portion, the second side of the air outlet convexly extends towards the exterior of the electrical appliance box to be provided with a second bending portion, and the free end of the first bending portion and the free end of the second bending portion respectively extend in the directions of the second side and the first side of the air outlet and respectively shield at least one portion of the air outlet. According to the air conditioner, the outdoor unit thereof and the electrical appliance box of the outdoor unit, cooled air is guided into the casing from the air inlet, flows through the control main board and then flows out from the air outlet, accordingly radiating is achieved, the radiating performance is improved, and the electrical appliance box has the advantages of being simple in structure and low in cost.

Description

technical field [0001] The present invention relates to the field of air conditioners, and more particularly, to an air conditioner, an outdoor unit thereof, and an electrical box for the outdoor unit. Background technique [0002] In the field of air conditioner frequency conversion, the failure of the control board damaged due to the high temperature of the components on the control board of the outdoor unit of the air conditioner accounts for a high proportion of after-sales failures, and the failure rate of the controller components used for frequency conversion varies with temperature. The increase increases exponentially, that is, its service life decreases exponentially with the increase of temperature. [0003] In the prior art, in order to reduce the temperature of the components on the control board, the following two methods are mainly adopted: (1) by increasing the size of the radiator, but increasing the cost of the whole machine; On the one hand, this method i...
