A fan motor heat dissipation structure for air conditioning internal units
A fan motor heat dissipation structure and air conditioner for an internal unit of an air conditioner, including a cross flow fan blade, a drive motor, and a heat dissipation component. The heat dissipation component is located on the cross flow fan blade, and the cross flow fan blade includes an original section and an expansion section. The original section and the expansion section are connected through a first cover plate, and the drive motor is at least partially embedded in the expansion section. The drive motor dissipates heat through the heat dissipation component, The part of the drive motor that is not embedded in the expansion section is cooled by direct air blowing, while the part of the drive motor that is embedded in the expansion section is cooled by the rotation of the heat dissipation component, causing air to flow towards the middle of the cross flow fan blades. The air takes away the heat and water vapor emitted from the surface of the drive motor, playing a cooling role in the drive motor. Therefore, the heat dissipation structure described in this utility model improves the uniformity of the heat dissipation of the drive motor and extends the service life of the drive motor.
