Problems solved by technology

[0002] The existing electric fan blows air to the human body to speed up the heat dissipation of the human body and make people feel cool. In fact, the electric fan does not reduce the air temperature. When the air temperature rises, the cooling effect of the electric fan becomes worse, and the feeling of coolness of the human body is also reduced.

Abstract

The invention relates to an air centrifugal refrigeration machine which comprises a shell, a motor, fan blades and a propeller boss. The air centrifugal refrigeration machine is characterized in thatthe motor, the fan blades and the propeller boss are arranged in the shell; a rotor shaft of the motor is connected with the propeller boss; the fan blades are arranged on the propeller boss and are hollow bodies; the inner parts of the fan blades are divided into a plurality of runners through a plurality of dividing pieces; the runners are radially distributed on the fan blades; the dividing pieces are straight lines or curve lines; air inlets of the runners are located at the root parts of the back faces of the fan blades; air outlets of the runners are connected with air inlets of throttlepipes; the throttle pipes are located in the end heads of the fan blades; and air outlets of the throttle pipes are located on the front faces of the end heads of the fan blades. Due to the action ofa centrifugal force, air is centrifuged, throttled and diffused, so that the temperature is reduced, and the aim on refrigerating is achieved.

Description

technical field [0001] The invention belongs to the field of air conditioning and refrigeration, and in particular relates to an air centrifugal refrigerator. Background technique [0002] Existing electric fans blow air to the human body to speed up the heat dissipation of the human body and make people feel cool. In fact, the electric fan does not lower the air temperature. Contents of the invention [0003] The object of the present invention is to provide an air centrifugal refrigerator capable of lowering the air temperature. [0004] The solution of the present invention is: the air centrifugal refrigerator includes a housing, a motor, a fan blade, and a hub, and is characterized in that the motor, the fan blade, and the hub are installed in the housing, the motor shaft is connected with the hub, and the fan blades are installed in the housing. On the shaft hub, the fan blade is a hollow body, and the interior is divided into several flow channels by a number of par...
