Description

Water cooling structure of motor of handheld electric tool Technical Field The utility model relates to the technical field of motors, in particular to a water cooling structure of a motor of a handheld electric tool. Background In the current motor application technical field, most of motor tools of traditional designs on the market adopt a water-cooling-free shell structure. The design has the obvious defect that a large amount of heat generated during the operation of the motor cannot be timely emitted due to the lack of an effective heat dissipation mechanism in the normal operation process of the motor, so that the temperature of the motor is continuously increased. The ageing and the damage of motor inside spare part can be accelerated to too high temperature, shortens the life of complete machine greatly, and in long-time use moreover, motor housing temperature is too high, and the user can have obvious scalding sensation when touching, has seriously influenced user's use experience. Therefore, how to effectively solve the heat dissipation problem during the operation of the motor, reduce the temperature of the motor, prolong the service life of the motor and improve the user experience becomes a key problem to be solved urgently in the current motor technical field.
