Abstract

The invention generally relates to the field of household appliances, in particular to a rotor assembly, a motor, a compressor and a refrigerating device, the rotor assembly comprises a rotor iron core, the rotor iron core is provided with a rotor hole and a magnetic steel groove, the rotor iron core is provided with a circulation hole for refrigerant circulation and a diversion trench formed in the bottom end of the rotor iron core. The circulation hole is communicated with the diversion trench, and one side, far away from the circulation hole, of the diversion trench is provided with an inclined diversion wall, so as to guide a refrigerant to flow into the circulation hole from the tangential direction and the radial direction of the rotor core, thereby accelerating the flowing speed ofthe refrigerant when the refrigerant enters the circulation hole, and improving the heat dissipation effect of the rotor core. The demagnetization risk of the permanent magnet is reduced, and the motor performance is improved.

Description

technical field [0001] The present application generally relates to the field of household appliances, and in particular, relates to a rotor assembly, a motor, a compressor and a refrigeration device. Background technique [0002] With the rapid development and wide application of refrigeration equipment, the rapid improvement of inverter compressor technology has been promoted. At present, the motor rotor of the commonly used frequency conversion compressor is provided with a circulation hole for the circulation of the refrigerant, and the heat energy generated by the rotor is conducted through the refrigerant to cool the motor. At present, the rotor assembly inside the compressor is mainly composed of the rotor core, permanent It consists of magnets, upper and lower baffles, main and auxiliary balance weights and screws. Among them, the flow holes of the rotor core provide refrigerant channels to dissipate heat from the rotor core. The circulation speed is slow and the hea...
