Description

Technical Field

[0001] The utility model relates to the technical field of cooling protection when a motor is working, in particular to a cooling structure of a motor. Background Art

[0002] In industrial production, motors are used as the power source for various industrial equipment. During operation, the internal temperature of the motor is too high, which can easily cause damage to the motor and seriously affect the service life of the motor. In order to ensure that the temperature of the motor is reduced when the motor is working, a motor cooling structure is usually used.

[0003] The cooling structure of a general motor is to set an evaporator tube for cooling on the outer ring of the motor, and circulate cooling water for cooling inside the evaporator tube to reduce the surface temperature of the motor. However, this structure is prone to frost on the surface of the motor, which is easy to damage the motor. A Chinese patent discloses a motor cooling structure based on coolant with application number "CN201810485107.8", in which the cooler is installed on the top of the shell; the sealing cover passes through the inner diameter of the stator core to cover the stator core, and extends to the inside of the cooler, isolating from the rotor core space in the shell to form a closed space; coolant is injected into the sealing cover to form a coolant pool; the ventilation pipe is located on the axial outside of the stator core, and both ends are connected to the rotor core space; a number of sub-plates are connected between the shaft and the rotor core, and the space between the sub-plates forms an axial air duct of the core; an air gap is formed between the rotor core and the inner circumference of the sealing cover; the internal fan is fixed to the shaft extension end of the shaft, and is used to generate a dynamic airflow in the rotor circulation air path composed of the rotor core space, the ventilation pipe, the axial air duct of the core, the radial air duct of the rotor core, and the air gap. The invention has two independent cooling circuits for the stator and rotor, but both absorb heat through the coolant, which reduces the complex cooling structure, improves the efficiency of the coolant, reduces the cost, and improves reliability. However, this structure does not solve the problem of achieving defrosting. Utility Model Content
