Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motor cooling, in particular to a series-excited motor cooling device. Background Art
[0002] A series-excited motor generally refers to a series-excited electric motor. A single-phase series-excited electric motor is commonly known as a series-excited electric motor. It is named because the excitation winding and the field winding are connected in series to work together. A single-phase series-excited electric motor is an AC / DC dual-purpose motor. It can use both AC and DC power supplies. With the continuous advancement of social industrial design technology, home appliances are developing in the direction of multi-function, long life, and intelligence. Therefore, for home appliances, enriching product functions and long-term use have become a problem that needs to be solved. Heat dissipation has always affected the service life of the motor. How to solve the heat dissipation of the motor is a more difficult problem.
[0003] When the existing series-excited motor is installed and used, the cooling fan is usually installed in the motor casing. Therefore, when inside the casing, the fan will be blocked by the casing and lose a certain degree of control over the wind force and direction inside the casing, resulting in the wind entering the casing not flowing quickly to the heat-generating components of the motor. As a result, the cooling and heat dissipation effects inside the motor are not ideal, and the motor heating speed is still affected by the motor in some environments where it needs to be used for a long time, resulting in the current use environment of the motor being restricted, which has brought certain adverse effects on people's use process. In order to solve the deficiencies of the prior art, we propose a series-excited motor cooling device. Utility Model Content

DETAILED DESCRIPTION
[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] Embodiment 1, as Figure 1-4 As shown, a series motor cooling device includes a series motor 1. The series motor 1 is installed with a power distribution device so that the rotor shaft roller 16 can be connected to the power distribution device. Then, a cooling device 2 is installed on the outside of the series motor 1. The connecting pipe 5 set at the lower end of the coolant pipe 4 is connected to the cooling assembly 12 set at the upper end of the series motor 1 through the coolant through hole 13 set on the inner side of the cooling assembly 12 set at the upper end of the series motor 1, and then connected to the outer water pipe through the liquid inlet 8. In this way, the installation of the cooling device 2 is completed. Subsequently, when the motor is working, the rotor rotates, and the high-frequency rotation action causes the internal temperature of the series motor 1 to increase. At this time, the cooling water flowing from the liquid inlet 8 is injected into the interior of the series motor 1 through the coolant through hole 13 box through the provided connecting pipe 5 under the push of the circulating pump 6. In this way, heat exchange can be carried out with the inside of the series motor 1, and the working series motor 1 can be quickly cooled, so that the heat inside the series motor 1 will not be excessively accumulated, and the cooling effect will not be poor due to the obstruction of the outer shell. The heat dissipation effect is good, and the operation of the series motor 1 is maintained.
[0023] Embodiment 2, as Figure 1-4As shown, a cooling device for a series-excited motor, the cooling water that absorbs high temperature inside the cooling component 12 and thus loses its cooling effect will also be connected to the coolant pipe 4 through the connecting pipe 5 as the cooling water is continuously injected, so as to complete the liquid exchange, and the heat dissipation fan 9 arranged inside the cooling device 2 will also assist in strengthening the cooling. When the weather is cold and the water may freeze, the heat dissipation fan 9 can cooperate with the rotating blades 10 arranged inside the series-excited motor 1 to rotate further to dissipate the heat of the series-excited motor 1, and will not be affected, and the use occasions are expanded. Since the added fan is installed inside the cooling device 2 arranged outside the motor, it will not cause bloated volume and affect the installation.
[0024] How it works
[0025] It should be noted that the utility model is a series motor cooling device. When in use, the series motor 1 is installed with the power distribution device so that the rotor shaft roller 16 can be connected to the power distribution device. Then, the cooling device 2 is installed on the outside of the series motor 1. The connecting pipe 5 set at the lower end of the coolant pipe 4 is connected to the cooling assembly 12 set at the upper end of the series motor 1 through the coolant through hole 13 set on the inner side. Then, it is connected to the outer water pipe through the liquid inlet 8. In this way, the installation of the cooling device 2 is completed. Then, when the motor is working, the rotor rotates, and the high-frequency rotation action causes the internal temperature of the series motor 1 to increase. At this time, the cooling water flowing from the liquid inlet 8 is injected into the interior of the series motor 1 through the coolant through hole 13 box through the provided connecting pipe 5 under the push of the circulating pump 6, so that heat exchange can be carried out with the inside of the series motor 1. The heat dissipation effect is good, and the operation of the series-excited motor 1 is maintained. The cooling water that absorbs high temperature and loses its cooling effect inside the cooling component 12 will also be connected to the coolant pipe 4 through the connecting pipe 5 as the cooling water is continuously injected, so as to complete the liquid exchange. The heat dissipation fan 9 arranged inside the cooling device 2 will also assist in strengthening the cooling. When the weather is cold and the water freezes, the heat dissipation fan 9 can cooperate with the rotating blades 10 arranged inside the series-excited motor 1 to rotate to further dissipate the heat of the series-excited motor 1, and will not be affected. The use occasions are expanded. Since the added fan is installed inside the cooling device 2 arranged outside the motor, it will not cause bloated volume and affect the installation.
