Description

Technical Field

[0001] The present invention relates to the technical field of motor covers, and in particular to an air-cooled motor cover which utilizes natural wind for cooling. Background Art

[0002] The motor cover in the prior art usually has several ventilation holes on the top of the cover to dissipate heat and cool the motor installed in the motor cover by means of natural wind circulation. However, when the motor is working under high load for a long time, the heat dissipated from the motor is difficult to dissipate quickly by relying on untreated natural wind, which can easily lead to abnormal temperature rise in the motor cover, causing motor failure, resulting in certain losses and dangers. Therefore, it is necessary to propose an air-cooled motor cover that uses natural wind for cooling to solve the above problems. Summary of the invention

[0003] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an air-cooled motor cover that uses natural wind for cooling.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A wind-cooled motor cover that uses natural wind for cooling, including a motor cover body, the upper end of the motor cover body is provided with ventilation holes, an air inlet pipe is fixedly installed above the ventilation holes, an annular liquid storage tank is fixedly connected to the side wall of the motor cover body, the annular liquid storage tank is filled with coolant, a serpentine cooling pipe is fixedly connected to the inner wall of the motor cover body near the inner top, a pump box is fixedly connected to the upper end of the motor cover body, a pumping mechanism for pumping coolant into the serpentine cooling pipe is installed in the pump box, and a reflux mechanism for allowing the coolant to flow back to the annular liquid storage tank is installed at the output end of the serpentine cooling pipe.

[0006] Preferably, the air inlet pipe is a trumpet-shaped structure with a large diameter at one end and a small diameter at the other end, and the end with the larger diameter of the air inlet pipe faces outward and the end with the smaller diameter faces inward, and the end with the smaller diameter of the air inlet pipe is embedded in the ventilation hole.

[0007] Preferably, the pumping mechanism includes a magnetic plug, which is sealingly and slidingly connected between the inner walls of the pump box, the end of the pump box is connected to the lower end of the annular liquid storage tank through a liquid inlet pipe, and the end of the pump box is connected to the liquid inlet end of the serpentine cooling pipe through a liquid outlet pipe, and a pushing mechanism for driving the magnetic plug to move horizontally back and forth is installed on the upper end of the motor cover body.

[0008] Preferably, the pushing mechanism comprises a wind cup and a permanent magnet block, the wind cup is rotatably connected to the upper end of the motor cover body via a rotating shaft, and the permanent magnet block is coaxially fixedly connected to the rotating shaft.

[0009] Preferably, a one-way valve is installed on the liquid inlet pipe, which only allows the coolant to flow from the annular liquid storage tank to the liquid pump box, and a one-way valve is installed on the liquid outlet pipe, which only allows the coolant to flow from the liquid pump box to the serpentine cooling pipe.

[0010] Preferably, the reflux mechanism comprises a reflux pipe, one end of which is connected to the liquid outlet end of the serpentine cooling pipe, and the other end of which is connected to the upper end of the annular liquid storage tank.

[0011] Preferably, a plurality of heat dissipation fins are embedded on the side wall of the annular liquid storage tank, and the heat dissipation fins are in contact with the coolant.

[0012] The present invention has the following beneficial effects:

[0013] 1. A trumpet-shaped air inlet pipe is provided, with the end with a larger diameter facing outward and the end with a smaller diameter facing inward. When the external natural wind flows through the air inlet pipe, the volume of the natural wind is compressed, which will reduce the temperature of the natural wind, so that the temperature of the natural wind entering the motor cover is lower than the temperature of the external natural wind, which can better cool the motor. At the same time, the flow rate of the natural wind is increased after the volume of the natural wind is compressed, which can drive the wind cup to rotate.

[0014] 2. By setting a serpentine cooling pipe, a pumping mechanism and a pushing mechanism, when the motor cover body protects the motor, natural wind blows through the top of the motor cover body, part of the natural wind is poured into the motor cover body from the air inlet pipe, part of the natural wind blows the wind cup to rotate, and the wind cup drives the permanent magnet block to rotate, and the magnetic sliding plug is pushed to slide back and forth horizontally under the action of magnetic force, so that the coolant is pumped into the serpentine cooling pipe, so that the serpentine cooling pipe is kept at a low temperature, and the temperature of the natural wind entering the motor cover body drops rapidly when passing through the serpentine cooling pipe, thereby providing a better heat dissipation and cooling effect for the motor, avoiding abnormal temperature increase in the motor cover body, and preventing the motor from causing working failures;

[0015] 3. By setting up a reflux mechanism and heat dissipation fins, the coolant can circulate in the serpentine cooling pipe and the annular liquid storage tank. The setting of the heat dissipation fins can ensure that the coolant is always at a low temperature state, thereby ensuring that the serpentine cooling pipe can also be always at a low temperature state, further ensuring that the temperature inside the motor cover body will not rise abnormally.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4 A wind-cooled motor cover that uses natural wind for cooling includes a motor cover body 2, each of which is provided with a ventilation hole 3 at the upper end of the motor cover body 2, an air inlet pipe 13 is fixedly installed above the ventilation hole 3, an annular liquid storage tank 4 is fixedly connected to the side wall of the motor cover body 2, and the annular liquid storage tank 4 is filled with coolant, a serpentine cooling pipe 5 is fixedly connected to the inner wall of the motor cover body 2 near the inner top, and a pump liquid box 8 is fixedly connected to the upper end of the motor cover body 2.

[0023] A pumping mechanism for pumping coolant into the serpentine cooling tube 5 is installed in the pumping box 8, and the pumping mechanism includes a magnetic sliding plug 1, which is sealingly and slidingly connected between the inner walls of the pumping box 8. The end of the pumping box 8 is connected to the lower end of the annular liquid storage tank 4 through the liquid inlet pipe 9, and the end of the pumping box 8 is connected to the liquid inlet end of the serpentine cooling tube 5 through the liquid outlet pipe 10. A pushing mechanism for driving the magnetic sliding plug 1 to move horizontally back and forth is installed on the upper end of the motor cover body 2.

[0024] The driving mechanism includes a wind cup 12 and a permanent magnet block 6. The wind cup 12 is rotatably connected to the upper end of the motor cover body 2 through a rotating shaft, and the permanent magnet block 6 is coaxially fixedly connected to the rotating shaft.

[0025] A one-way valve is installed on the liquid inlet pipe 9 to allow only the coolant to flow from the annular liquid storage tank 4 to the pump liquid box 8 , and a one-way valve is installed on the liquid outlet pipe 10 to allow only the coolant to flow from the pump liquid box 8 to the serpentine cooling pipe 5 .

[0026] A reflux mechanism is installed at the output end of the serpentine cooling pipe 5 for returning the coolant to the annular liquid storage tank 4. The reflux mechanism includes a reflux pipe 11. One end of the reflux pipe 11 is connected to the liquid outlet end of the serpentine cooling pipe 5, and the other end of the reflux pipe 11 is connected to the upper end of the annular liquid storage tank 4.

[0027] A plurality of heat dissipation fins 7 are embedded on the side wall of the annular liquid storage tank 4, and the heat dissipation fins 7 are in contact with the coolant.

[0028] The air inlet pipe 13 is a trumpet-shaped structure with a large diameter at one end and a small diameter at the other end. The larger diameter end of the air inlet pipe 13 faces outward and the smaller diameter end faces inward. The smaller diameter end of the air inlet pipe 13 is embedded in the ventilation hole 3.

[0029] In the present invention, when the motor cover body 2 protects the motor, natural wind blows through the top of the motor cover body 2, and part of the natural wind is poured into the motor cover body 2 from the air inlet pipe 13 of the ventilation hole 3. When the natural wind flows through the air inlet pipe 13, due to the trumpet-shaped structure of the air inlet pipe 13, the natural wind entering the air inlet pipe 13 is compressed, thereby reducing the temperature of the natural wind, thereby reducing the temperature of the wind entering the motor cover body 2, and can better take away the heat generated when the motor is running. At the same time, since the natural wind is compressed, the wind speed entering the motor cover body 2 is increased, and part of the natural wind blows the wind cup 12 to rotate The wind cup 12 drives the permanent magnet block 6 to rotate. Under the action of magnetic force, when the permanent magnet block 6 and the magnetic slider 1 are opposite to each other with the same poles, the permanent magnet block 6 pushes the magnetic slider 1 away. When the permanent magnet block 6 and the magnetic slider 1 are opposite to each other with different poles, the permanent magnet block 6 attracts the magnetic slider 1 to move closer, thereby realizing the horizontal reciprocating sliding of the magnetic slider 1, and pumping the coolant into the serpentine cooling pipe 5 to keep the serpentine cooling pipe 5 at a low temperature. The temperature of the natural wind entering the motor cover body 2 drops rapidly when passing through the serpentine cooling pipe 5, thereby providing a better heat dissipation and cooling effect for the motor, avoiding abnormal temperature increase in the motor cover body 2, and preventing the motor from causing working failures.

[0030] And under the action of the reflux pipe 11, the coolant circulates in the serpentine cooling pipe 5 and the annular liquid storage tank 4. The setting of the heat dissipation fins 7 ensures that the coolant is always at a low temperature state, thereby ensuring that the serpentine cooling pipe 5 is always at a low temperature state, further ensuring that the temperature in the motor cover body 2 will not rise abnormally.
