Description
Technical Field
The invention relates to a liquid cooling shell of a permanent magnet motor, in particular to a novel liquid cooling self-circulation shell of a high-power density permanent magnet motor, and belongs to the technical field of motors.
Background
In a closed environment, a traditional water cooling system of a high-power density permanent magnet motor circulates cooling water by installing a water pump for providing power outside a shell of the high-power density permanent magnet motor, and the traditional water cooling system usually needs an external heat dissipation device. The power pump and the heat dissipating device not only increase the running cost of the motor and cause energy waste, but also limit the service performance and the service life of the shell of the high-power density permanent magnet motor, and hardly meet the requirements of energy conservation and environmental protection of the water cooling system of the high-power density permanent magnet motor in a closed environment.
Because the traditional cooling system in the closed environment needs an external power pump and a heat dissipation device, the disassembly and the transportation of the shell of the permanent magnet motor with high power density are inconvenient.
Disclosure of Invention
The following presents a simplified summary of the invention in order to provide a basic understanding of some aspects of the invention.

It is not intended to identify key or critical elements of the invention or to delineate the scope of the invention. Its purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is discussed later.
In view of the above, the present invention provides a novel high power density permanent magnet motor liquid cooling self-circulation casing to at least solve the problems of high operation cost, resource waste, and inconvenience in disassembly and transportation of the high power density permanent magnet motor casing due to the existence of an external power pump and a heat dissipating device in a closed environment.
The invention provides a novel liquid cooling self-circulation shell of a high-power density permanent magnet motor, which comprises a motor outer shell, an intermediate layer and a motor inner shell, wherein the three parts are coaxially arranged from outside to inside, and two ends of the three parts are connected through an annular baffle plate to form a cooling cavity; the upper part of the middle layer is provided with an upper arc-shaped notch, the edge of the upper arc-shaped notch is provided with a baffle plate, an evaporation chamber is formed between the baffle plate and the motor inner shell as well as between the baffle plate and the motor outer shell, and the lower part of the middle layer is provided with a lower arc-shaped notch; the liquid injection pipe is arranged on the upper portion of the motor shell, the liquid discharge pipe is arranged on the lower portion of the motor shell, the installation position of the liquid injection pipe corresponds to the upper circular arc-shaped notch, the installation position of the liquid discharge pipe corresponds to the lower circular arc-shaped notch, and cooling liquid is injected into the cooling cavity through the liquid injection pipe.
In the invention, the middle layer divides the cooling liquid into an inner layer and an outer layer, thereby accelerating the cooling circulation of the liquid. The partition plate is contacted with the liquid level of the cooling liquid, so that the volume of the evaporation chamber is increased, the evaporation area of the liquid is increased, and the inner-layer liquid can only evaporate after absorbing heat and cannot directly flow to the outer layer. The lower arc-shaped notch at the lower part of the middle layer is communicated with the motor outer shell and the motor inner shell, so that the liquid at two sides of the middle layer is kept at the same height, and the liquid can be effectively recycled.
Further: the motor outer shell is made of an aluminum alloy material, aluminum radiating fins are arranged outside the motor outer shell, the motor inner shell is made of an aluminum material, the middle layer is made of an aluminum alloy material, and an insulating and heat-insulating layer is coated on the middle layer. By the arrangement, the material cost is reduced, and the heat insulation function is realized, so that the evaporation rate of liquid is increased.
Further: the upper part of the motor shell is provided with a pressure detection pipe, the mouth of the pressure detection pipe is provided with a pressure detection valve, and the installation position of the pressure detection pipe corresponds to the upper circular arc-shaped notch. The pressure detecting valve is used for detecting the pressure in the shell, and the pressure detecting valve is opened when the pressure in the shell reaches a certain value, so that the shell is effectively prevented from deforming.
Further: the aluminum heat dissipation fins are hollow structures. By the arrangement, material cost is saved, heat dissipation area of the shell is increased, and cooling time of liquid is shortened.
Further: the axial distance between the motor inner shell and the middle layer is equal to the axial distance between the motor outer shell and the middle layer.
Further: the bottom of the motor shell is provided with supporting feet. The arrangement is beneficial to the stability of the device.
Further: the mouth of the liquid injection pipe is provided with a pipe cover, and the mouth of the liquid discharge pipe is provided with a pipe plug. So set up, convenient to use.
Further: the annular baffle is made of metal materials. By the arrangement, the material cost is saved.
Further: the end covers are arranged at two ends of the liquid cooling self-circulation shell of the novel high-power density permanent magnet motor.
The beneficial effects are that:
the invention injects a certain amount of cooling liquid into the shell, and divides the cooling liquid into an inner layer and an outer layer by the middle layer. The inner layer liquid is heated and then quickly evaporated in an evaporating chamber formed by the partition plate, the motor inner shell and the motor outer shell, the motor outer shell with relatively low upper layer temperature is encountered to be liquefied, and the outer layer liquid flows into the outer layer along the inner wall of the annular motor outer shell. The invention effectively solves the problems of energy waste and inconvenient transportation and disassembly caused by the need of external water source and water circulation power supply due to poor heat dissipation effect and high material cost of the traditional liquid cooling high-power density permanent magnet motor shell in a closed environment.
