Embodiment 1

[0029] Please combine Figure 1 to Figure 7 , a three-phase motor with a cooling device, comprising a body 1 and a cooling device for cooling the body 1 . In this embodiment, the body 1 and the cooling device are installed on the base 10 . The base 10 can be an ordinary motor mounting frame to effectively support the body 1 . The heat dissipation device includes a heat exchange tank 2 and a water tank 4. The heat exchange tank 2 is fixed around the outer peripheral side of the body 1. In this embodiment, the side of the heat exchange tank 2 facing the body 1 as a whole is completely attached to the outside of the body 1 to cover the surface of the body. The heat dissipated in the heat-generating area is conducted to the inside of the heat exchange tank 2 . The heat exchange tank 2 can be fixed on the shell of the body 1 by screws, which is convenient for installation and disassembly. The side of the heat exchange tank 2 facing the body 1 is provided with a heat conduction l...

Embodiment 2

[0042] Please combine Figure 8 , this embodiment 2 is an improved solution of embodiment 1, specifically, the top of the deflector 8 is provided with a plurality of water blocking grooves 18 at equal intervals along its inclination direction, and the cross section of the water blocking grooves 18 is a right triangle. The time for the water flow to pass through the top of the deflector 8 can be extended by the water blocking groove 18, and the water droplets in the water flow will splash when they flow out of the water blocking groove 18, so that the contact time between the water flow and the air becomes longer, and the cooling rate of the water flow is improved.

Abstract

The invention relates to the technical field of three-phase motors, and discloses a three-phase motor with a cooling device, which includes a body and a cooling device for cooling the body. The cooling device includes a heat exchange tank and a water tank, and the heat exchange tank is fixed around the body On the outer peripheral side, the side of the heat exchange tank facing the body is provided with a heat conduction layer that fits the shell of the body, and the side of the heat exchange tank facing away from the body is evenly equipped with a plurality of cooling fins. Cooling water for thermal cooling. The three-phase motor with heat dissipation device of the present invention replaces the heat dissipation method of the traditional three-phase motor. Through the heat exchange tank surrounding the outside of the body, the heat generated by the operation of the body can be quickly exchanged and cooled, and the temperature of the body is improved. The heat dissipation efficiency and heat dissipation effect ensure the normal operation of the body. At the same time, the exhaust fan, deflector and blower in the water tank can increase the heat dissipation speed of the water after heat exchange, so as to ensure the heat exchange stability of the water in the water tank when participating in each heat exchange cycle.

Description

technical field [0001] The invention relates to the technical field of three-phase motors, in particular to a three-phase motor with a cooling device. Background technique [0002] A three-phase motor means that when the three-phase stator windings of the motor (each with a phase difference of 120 degrees in electrical angle) are connected to the three-phase alternating current, a rotating magnetic field will be generated, and the rotating magnetic field will cut the rotor winding, thereby generating an induced current in the rotor winding ( The rotor winding is a closed path), and the current-carrying rotor conductor will generate electromagnetic force under the action of the rotating magnetic field of the stator, thereby forming an electromagnetic torque on the motor shaft, driving the motor to rotate, and the direction of rotation of the motor is the same as that of the rotating magnetic field. [0003] The body of the three-phase motor will generate a lot of heat during ...
