Abstract
The invention belongs to the technical field of air conditioners, and particularly relates to an air conditioner outdoor unit which comprises an outdoor unit body. A fan, a condenser, an electric controller and an air flue pipe are arranged in the outdoor unit body, wherein an air flow cavity is formed between the condenser and the fan, an air flue cavity formed in the air flue pipe enables the air flow cavity and the exterior of the air flow cavity to be communicated, an electric control plate of the electric controller is installed on the air flue pipe, the electric control plate is separated from the air flue cavity formed in the air flue pipe, and a radiator and a capacity component are arranged in the air flue cavity formed in the air flue pipe or a cavity mouth of the air flue cavity. When in use, an air flow is directly introduced from the exterior of the air flow cavity through the air flue pipe for cooling the radiator and the capacity component of the electric controller, and therefore heat exchanging effects of the radiator and the capacity component are improved. Due to the fact that the electric control plate is separated from the air flue cavity formed in the air flue pipe, dust in the air flow flowing through the air flue cavity is prevented from contacting with the electric control plate, and therefore the service life of the electric control plate is prolonged, and reliability of the electric control plate is improved. As a whole, stability of working of components of the electric controller is improved, and quality and price-performance ratio of the products are enhanced.
