Description

Technical Field

[0001] The utility model belongs to the technical field of motor radiators, and in particular relates to a radiator applied to a motor. Background Art

[0002] Due to the precise control requirements of the motor, when the motor works continuously, its internal structure will generate a lot of heat during operation. In addition, the heat dissipation capacity of the motor itself is limited, which can easily cause the temperature of the motor to continue to rise. When the temperature of the motor reaches a high temperature, it will directly affect the working performance and service life of the motor. At present, it is common to increase the heat dissipation area of ​​the motor or use a fan to dissipate heat to the motor. However, increasing the heat dissipation area of ​​the motor can easily lead to an increase in the volume and weight of the motor; using a fan for cooling can easily lead to insufficient air volume, resulting in insufficient heat dissipation of certain parts of the motor, especially in the hot spots of the motor, which may cause temperature accumulation, thereby causing fatigue of the internal parts of the motor and shortening the service life. To this end, the utility model proposes a new technical solution to the above technical problems. Utility Model Content
