Embodiment 1

[0036] Such as figure 1 , 5 , 6, 7, 8, the casing 1 includes an inner cavity, and the stator component 10 is fixed in the cavity of the casing 1; the rotor component 9 is located in the middle of the stator component 10.

[0037] In the body wall of the casing 1, there are more than two liquid storage holes 11 that are independent of each other along the axial direction and all run through the front and rear ends of the body wall of the casing 1 to form a liquid storage chamber 8; The liquid chamber 8 is connected with a liquid inlet and a liquid outlet, which are respectively in airtight communication with the radiator 5 through a plurality of connecting pipes 4 .

[0038] The connecting pipe 4 can be made of stainless steel.

[0039] Preferably, in the body wall of the casing 1, a plurality of mutually independent liquid storage holes 11 are provided along the axial direction, all of which run through the front and rear ends of the body wall of the casing 1, and the liquid...

Embodiment 2

[0045] Such as figure 2 , 9 , 10, in order to ensure a compact structure, in this embodiment, the radiator 5 is installed outside the casing 1 close to the casing 1; the cooling fan 6 is located outside the end of the casing 1.

[0046] In the body wall of the casing 1, a first group of spiral tubes 12 are inlaid to form a second liquid storage chamber 81; the liquid storage chamber 81 is connected with a liquid inlet 13 and a liquid outlet 14, which are respectively connected to the heat dissipation through the connecting pipe 4. The radiating pipe of device 5 is airtightly communicated.

[0047] The liquid storage tank 7 is located above the radiator 5 and communicates with the heat dissipation pipe of the radiator 5 in a sealed manner.

[0048] In particular, if the power of the motor is hundreds or thousands of kilowatts, a group of spiral tubes will be added at both ends of the coil of the motor to improve the cooling capacity of the motor. A second set of helical tubes...

Abstract

The invention provides a superconductive radiating motor, which greatly improves cooling capacity and is high in power density, small in size, light in weight and high in efficiency. The superconductive radiating motor comprises a shell part, a stator part and a rotor part, wherein the shell part comprises a pipeline-shaped shell; and the stator part and the rotor part are positioned in an inner cavity of the shell. The superconductive radiating motor also comprises a superconductive radiating liquid cooling system, wherein a liquid storage cavity is formed in a body wall of the shell; the superconductive radiating liquid cooling system comprises a radiator, a radiating fan and a connecting pipe for connecting the radiator and the liquid storage cavity; heat superconductive liquid is positioned in a closed channel which is formed by the liquid storage cavity, the radiator and the connecting pipe; the heat superconductive liquid cooling system comprises a liquid storage box which is communicated with the radiator and stores the heat superconductive liquid; the inner cavity of the shell has a front-end opening and a rear-end opening; a front end cover closes the front-end opening; and a rear end cover is arranged at the rear-end opening of the shell and closes the rear-end opening.

Description

technical field [0001] The invention belongs to the technical field of electric motors, and relates to a cooling system of electric motors, in particular to a high-power superconducting heat-dissipating electric motor cooled by cooling liquid. Background technique [0002] 1) At present, the power density of ordinary industrial motors is about 0.5KW / kg. When designing a pure electric vehicle project for energy saving and emission reduction, a motor with a motor power density greater than 1.5Kw / kg is required, so that the motor power of the same volume is increased. At the same time, the thermal load of the motor is also increased by 9 times, and the loss per unit volume generated during the operation of the motor increases, causing the temperature of each part of the motor to rise, which directly affects the life of the motor and the reliability of operation. [0003] 2) The efficiency improvement and active temperature adjustment of the motor are mainly realized through the...
