Description

Technical Field

[0001] The present invention relates to the technical field of electric motors, and in particular to an energy-saving electric motor with a high-efficiency heat dissipation structure. Background Art

[0002] High-efficiency, energy-saving motors are standard, general-purpose motors with enhanced efficiency. They utilize innovative motor designs, processes, and materials to improve output efficiency by reducing electromagnetic, thermal, and mechanical energy losses. Compared to standard motors, high-efficiency motors offer significant energy savings, typically increasing efficiency by an average of 4%.

[0003] There are various ways to dissipate heat in electric motors, including natural cooling, fan-forced cooling, liquid cooling, heat pipe cooling, and combined cooling. For large and medium-sized motors, the internal air duct structure is complex, which can easily cause local heat accumulation. Therefore, most iron cores have axial and radial ventilation ducts, and internal fans are installed at one or both ends of the motor rotor to allow the internal cooling medium air to form an independent circulation system along a reasonable path. In this way, during the operation of the motor, the fan rotates to exhaust the hot air inside the motor, increasing the gas flow rate inside the motor to help the heat generated inside the motor be transferred to the outside more quickly, thereby achieving the purpose of cooling the motor. However, after the heat inside the motor is exhausted by the fan, this flowing hot air will directly contact the motor casing, causing the temperature of the outside of the motor to rise. As a result, its heat dissipation effect will gradually deteriorate during the operation of the motor, resulting in defects during use. Summary of the Invention

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1-Figure 5 The figure shows an energy-saving motor with an efficient heat dissipation structure, which includes a motor body 1, a support base 2 is fixedly installed at the lower end of the motor body 1, a fan 3 is rotatably installed inside the motor body 1, a cover shell 4 is provided on the outer side of the support base 2, and the connection between the cover shell 4 and the motor body 1 is a fixed connection. It also includes a wind collecting cover 5 for collecting the gas exhausted from the inside of the motor body 1, and the wind collecting cover 5 is installed at the right end of the cover shell 4; a condensing coil 10 for cooling the exhaust gas from the inside of the motor body 1, and the condensing coil 10 is installed on the right side of the wind collecting cover 5; a conical air guide cover 14 for guiding the gas cooled by the condensing coil 10 to the motor body 1, and the conical air guide cover 14 is installed on the outer side of the condensing coil 10.

[0021] A plurality of heat dissipating fins 6 equidistantly distributed around the circumference are fixedly mounted on the outside of the wind collecting cover 5 . The wind collecting cover 5 is funnel-shaped, and the diameter of the right end of the wind collecting cover 5 is smaller than the diameter of the condensing coil 10 .

[0022] A bending connecting rod 7 is installed on the lower right side of the motor body 1, and the connection between the bending connecting rod 7 and the support base 2 is a fixed connection. The end of the bending connecting rod 7 away from the support base 2 is fixedly connected to a fixing plate 8, and a pin 9 is fixedly embedded in the center of the side of the fixing plate 8 away from the condensing coil 10. The cross-sectional shape of the pin 9 is rectangular, and the corners are chamfered. A baffle 11 is movably sleeved on the outer side of the pin 9.

[0023] The connection between the baffle 11 and the fixed disk 8 is a movable fit. A connecting seat 12 is fixedly installed at the center of the side of the baffle 11 away from the fixed disk 8. A plug-in slot 13 is provided in the center of the baffle 11 and the connecting seat 12. The cross-sectional shape of the plug-in slot 13 is equal to the cross-sectional shape of the pin 9, and the baffle 11 and the connecting seat 12 are both movably connected to the outside of the pin 9 through the plug-in slot 13. The conical air deflector 14 and the baffle 11 are an integrally formed structure.

[0024] Working Principle: When the motor body 1 is running, its internal fan 3 rotates to discharge the heat inside the motor body 1. The gas discharged from the motor body 1 is collected by the wind collecting cover 5 and discharged through the smaller end of the wind collecting cover 5. During the flow process, the discharged gas exchanges heat with the condensing coil 10 (coolant flows through the condensing coil 10 through the pump body), which can cool the gas discharged from the motor body 1, thereby preventing the heat-containing gas discharged from the motor body 1 from causing the temperature outside the motor body 1 to rise, and preventing the gas discharged from the motor body 1 from affecting the heat dissipation effect of the motor body 1; After the gas exchanges heat with the condensing coil 10, it will be blocked by the baffle 11 and the conical air guide hood 14, and backflow will occur under the action of the conical air guide hood 14, causing the cooled gas to flow toward the motor body 1, which not only speeds up the gas flow rate outside the motor body 1, but also the cooled gas will exchange heat with the outer casing of the motor body 1 during the flow process, which is beneficial to further improve the heat dissipation effect of the motor body 1. Example 2: Please refer to Figure 1 、 Figure 5 This embodiment further explains the first embodiment. Two symmetrically distributed positioning seats 23 are fixedly installed on the upper end of the conical air guide cover 14. Rings 24 are installed on the inner sides of the two positioning seats 23. The shape of the rings 24 is U-shaped.

[0025] The collar 24 is rotatably connected to the positioning seat 23 via the positioning shaft 25 , a stopper 26 is fixedly mounted on the upper end of the cover shell 4 , and the connection between the collar 24 and the stopper 26 is a movable sleeve connection, and the collar 24 is sleeved on the outside of the stopper 26 , which can enhance the stability of the baffle 11 .

[0026] In this embodiment: after installing the baffle 11, the personnel rotates the ring 24 so that the ring 24 rotates and is sleeved on the outside of the block 26, which is beneficial for enhancing the stability of the baffle 11 when the fan 3 rotates and the gas flows, and preventing the baffle 11 from shaking under the impact of the flowing gas, thereby shortening the service life of the baffle 11. Example 3: Please refer to Figure 6-Figure 8 This embodiment further explains Example 1. A connecting component is installed inside the connecting seat 12. The connecting component includes two symmetrically distributed pins 15 that are movably embedded in the outside of the pin column 9. The cross-sectional shape of the pins 15 is circular. The two pins 15 can move up and down inside the connecting seat 12. Two symmetrically distributed oblique connecting rods 16 are movably hinged on the outside of the pins 15.

[0027] A connecting column 17 is hingedly installed at one end of the oblique connecting rod 16 away from the pin 15, and two symmetrically distributed buttons 18 are movably embedded on the outer side of the connecting seat 12, and the connection between the connecting column 17 and the button 18 is a fixed connection. An anti-slip groove is provided on the outer side of the button 18, and two symmetrically distributed pin holes 19 are provided on the outer side of the pin column 9.

[0028] The latch 15 is connected to the pin 9 through the pin hole 19, and a gasket 20 is fixedly sleeved on the outer side of the end of the connecting column 17 away from the button 18. The gasket 20 is used to prevent the connecting column 17 from being separated from the connecting seat 12. A limiting rod 21 is movably embedded in the center of the end of the connecting column 17 away from the button 18.

[0029] The connection between the limiting rod 21 and the connecting column 17 and the button 18 is plug-in contact. The outer side of the limiting rod 21 is movably sleeved with a spring 22. The limiting rod 21 is used to prevent the spring 22 from bending and getting stuck, and the two ends of the spring 22 are movably in contact with the connecting seat 12 and the gasket 20 respectively.

[0030] In this embodiment: when personnel need to clean or inspect the condensing coil 10, the personnel press the button 18 with two fingers to make the button 18 enter the inside of the connecting seat 12. When the two buttons 18 approach each other, the four oblique connecting rods 16 drive the two latches 15 to move away from each other. The two latches 15 will detach from the pin 9 during the movement. At this time, the personnel can directly remove the baffle 11 from the pin 9, which is convenient for the personnel to directly contact the condensing coil 10, thereby facilitating the personnel to clean or inspect the condensing coil 10 and avoiding the accumulation of a large amount of dust on the outside of the condensing coil 10 that affects the heat exchange of the condensing coil 10.
