Description
Technical Field
[0001] The utility model relates to the technical field of motor rotors, in particular to an electric motor rotor with a conformal heat pipe. Background Art
[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses the electromagnetic principle that a current-carrying conductor is acted upon by a force in a magnetic field. Through the interaction of current and magnetic field, the rotor rotates within the stator, thereby outputting mechanical energy. Electric motors generate a large amount of heat during operation. If the heat is not dissipated in time, it may cause the equipment to overheat, be damaged, or even burn out.
[0003] Currently, electric motors dissipate heat by installing cooling fins on the outside of the housing. However, as the motor ages, relying solely on these fins for heat dissipation is inevitably insufficient. Furthermore, heat is transferred to the outside of the housing via air, and the heat from the rotor cannot be removed promptly. As the motor ages, this inevitably affects its normal operation. Therefore, an electric motor rotor with a conformal heat pipe has been proposed. Utility Model Content
[0004] The purpose of the present invention is to provide an electric motor rotor with a conformal heat pipe to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an electric motor rotor with a conformal heat pipe, comprising a rotor body, a plurality of heat dissipation components installed on the outside of the rotor body, the plurality of heat dissipation components being equidistantly distributed, the heat dissipation components comprising a heat pipe body placed outside the rotor body, the heat pipe body being arranged parallel to the rotor body, a plurality of mounting blocks being fixedly connected to the circumferential outer wall of the rotor body, the plurality of mounting blocks being arranged parallel to the heat pipe body, the plurality of mounting blocks being provided with inclined limiting grooves inside, the plurality of limiting grooves being slidably connected to the insides of the plurality of fixing plates, and the plurality of fixing plates being able to fit the outer wall of the heat pipe body.
[0006] As a further preferred embodiment of the present technical solution, a mounting bar is placed on the circumferential outer wall of the rotor body, and a plurality of drive plates are fixedly connected to the top outer wall of the mounting bar, and the plurality of drive plates can respectively contact both sides of the circumferential outer walls of the plurality of extension columns.
[0007] The heat generated by the motor rotor during operation can be absorbed in time and dissipated outwards, avoiding the influence of untimely heat dissipation on the normal operation of the motor. The heat generated by the rotor is first absorbed by the heat pipe body, and the coolant inside the heat pipe body evaporates and diffuses. When it moves to the cooling end, the heat is dissipated and liquefied, and then flows back to the heat absorption end, thus reciprocating. The fixing plate used to fix the heat pipe body slides in the limit groove, and the extension column connected to the fixing plate is restricted by the driving plate, so that the position of the fixing plate can be guaranteed not to change at will, so that the heat pipe body can fit tightly against the outer wall of the rotor body, ensuring that the heat emitted by the rotor body can be absorbed in time.
[0008] As a further preferred embodiment of the present technical solution, a fastening assembly is installed inside the rotor body, and the fastening assembly includes a plurality of support plates fixedly connected inside the rotor body, and a horizontally arranged stabilizing rod is fixedly connected inside each of the plurality of support plates, and a plurality of the stabilizing rod sliding sleeves are provided with the same connecting frame, wherein a horizontally arranged screw rod is rotatably connected inside one of the support plates, and a knob adapted to the screw rod is rotatably connected outside the support plate, and the connecting frame is threadedly connected to the screw rod.
[0009] If the heat pipe body needs to be replaced, just drive the screw rod to rotate through the knob. The connecting frame restricted by multiple stabilizing bars can only move along the fixed level. Therefore, it will move to one side under the drive of the screw rod. The screw rod drives multiple mounting strips to move synchronously. The mounting strip drives the extension column to move through the driving plate, and then the fixed plate will be driven to move upward along the limit slot. Then the heat pipe body will no longer be restricted and can be easily removed.
[0010] As a further preferred embodiment of the present technical solution, the circumferential outer walls of the plurality of heat pipe bodies are each provided with a fitting groove, and the fitting groove can fit with the outer wall of the rotor body.
[0011] As a further preferred embodiment of the present technical solution, rubber pads are provided on the inner circumferential walls of the plurality of fixing plates.
[0012] As a further preferred embodiment of the present technical solution, one end of each of the heat pipe bodies is completely exposed to the outside air.
[0013] As a further preferred embodiment of the present technical solution, the heat dissipation component and the fastening component are both made of aluminum alloy.
[0014] The utility model provides an electric motor rotor with a conformal heat pipe, which has the following beneficial effects:
[0015] (1) The present invention sets a heat dissipation component so that the heat generated by the motor rotor during operation can be absorbed and dissipated outward in time, avoiding the influence of untimely heat dissipation on the normal operation of the motor. The heat generated by the rotor is first absorbed by the heat pipe body, and the coolant inside the heat pipe body evaporates and diffuses. When it moves to the cooling end, the heat is liquefied and then flows back to the heat absorption end, thus reciprocating. The fixed plate used to fix the heat pipe body slides in the limit groove, and the extension column connected to the fixed plate is restricted by the driving plate. Therefore, it can be ensured that the position of the fixed plate will not change arbitrarily, so that the heat pipe body can fit tightly against the outer wall of the rotor body, ensuring that the heat dissipated by the rotor body can be absorbed in time.
[0016] (2) The utility model sets a fastening component. If the heat pipe body needs to be replaced, the screw rod is driven to rotate by the knob. The connecting frame restricted by multiple stabilizing rods can only move along a fixed horizontal direction. Therefore, it will move to one side under the drive of the screw rod. The screw rod drives multiple installation bars to move synchronously. The installation bars drive the extension column to move through the driving plate, and then the fixing plate will be driven to move upward along the limit groove. Then the heat pipe body will no longer be restricted and can be easily removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0023] The utility model provides a technical solution: Figure 1 and Figure 2As shown, in this embodiment, an electric motor rotor with a conformal heat pipe includes a rotor body 1, a plurality of heat dissipation components 3 are installed on the outside of the rotor body 1, and the plurality of heat dissipation components 3 are distributed at equal distances. The heat dissipation components 3 include a heat pipe body 304 placed on the outside of the rotor body 1, and the heat pipe body 304 is arranged parallel to the rotor body 1. A plurality of mounting blocks 301 distributed at equal distances are fixedly connected to the circumferential outer wall of the rotor body 1, and the plurality of mounting blocks 301 are arranged parallel to the heat pipe body 304. The plurality of mounting blocks 301 are each provided with an inclined limiting groove 302 inside, and the plurality of limiting grooves 302 are each slidably connected to a fixing plate 303 inside, and the plurality of fixing plates 303 can fit the outer wall of the heat pipe body 304.
[0024] A mounting bar 306 is placed on the outer circumferential wall of the rotor body 1 , and a plurality of driving plates 307 are fixedly connected to the outer wall at the top of the mounting bar 306 . The plurality of driving plates 307 can respectively contact both sides of the outer circumferential wall of the plurality of extension columns 305 .
[0025] The heat generated by the rotor is first absorbed by the heat pipe body 304, and the coolant inside the heat pipe body 304 evaporates and diffuses. When it moves to the cooling end, it dissipates heat and liquefies, and then flows back to the heat absorption end, thus reciprocating. The fixing plate 303 used to fix the heat pipe body 304 slides in the limiting groove 302, and the extension column 305 connected to the fixing plate 303 is restricted by the driving plate 307. Therefore, it can be ensured that the position of the fixing plate 303 will not change arbitrarily, so that the heat pipe body 304 can fit tightly against the outer wall of the rotor body 1, ensuring that the heat emitted by the rotor body 1 can be absorbed in time.
[0026] like Figure 1 and Figure 4 As shown, a fastening assembly 4 is installed inside the rotor body 1, and the fastening assembly 4 includes multiple support plates 401 fixedly connected inside the rotor body 1, and a horizontally arranged stabilizing rod 402 is fixedly connected inside the multiple support plates 401. The multiple stabilizing rods 402 are slidingly sleeved with the same connecting frame 403, and a horizontally arranged screw rod 404 is rotatably connected inside one of the support plates 401, and a knob adapted to the screw rod 404 is rotatably connected outside the support plate 401, and the connecting frame 403 is threadedly connected to the screw rod 404.
[0027] If the heat pipe body 304 needs to be replaced, just drive the screw rod 404 to rotate through the knob. The connecting frame 403, which is restricted by multiple stabilizing rods 402, can only move along a fixed horizontal line. Therefore, it will move to one side under the drive of the screw rod 404. The screw rod 404 drives multiple mounting bars 306 to move synchronously. The mounting bars 306 drive the extension column 305 to move through the driving plate 307, and then the fixing plate 303 will be driven to move upward along the limiting groove 302. Then the heat pipe body 304 will no longer be restricted and can be easily removed.
[0028] like Figure 3 As shown, the outer walls of the circumference of the multiple heat pipe bodies 304 are all provided with fitting grooves 308, which can fit with the outer wall of the rotor body 1, so that the heat pipe bodies 304 can better fit the shape of the rotor body 1, which is conducive to improving the heat absorption effect.
[0029] like Figure 2 As shown, rubber pads 2 are provided on the inner circumference walls of the plurality of fixing plates 303 , which are beneficial to increase the friction between the fixing plates 303 and the heat pipe body 304 , and the heat pipe body 304 is not hindered when deformed by heat.
[0030] like Figure 1 As shown, one end of the plurality of heat pipe bodies 304 is completely exposed to the outside air, so that the contact area between the heat pipe body 304 and the air is large enough, which is beneficial to improving the condensation efficiency of the steam.
[0031] like Figure 1 As shown, the heat dissipation component 3 and the fastening component 4 are both made of aluminum alloy, which ensures that the accessories are light enough while making them stronger, and the heat dissipation effect of the aluminum alloy is also good enough.
[0032] The utility model provides an electric motor rotor with a conformal heat pipe, and the specific working principle is as follows:
[0033] When the device is working, the heat generated by the rotor is first absorbed by the heat pipe body 304 when the motor is running, and the coolant inside the heat pipe body 304 evaporates and diffuses. When it moves to the cooling end, the heat is liquefied and then flows back to the heat absorption end, thus reciprocating. The fixing plate 303 used to fix the heat pipe body 304 slides in the limit groove 302, and the extension column 305 connected to the fixing plate 303 is restricted by the driving plate 307. Therefore, it can be ensured that the position of the fixing plate 303 will not change arbitrarily, so that the heat pipe body 304 can fit tightly against the outer wall of the rotor body 1, ensuring that the heat emitted by the rotor body 1 can be absorbed in time. If the heat pipe body 304 needs to be replaced, just drive the screw rod 404 through the knob. The connecting frame 403 is restricted by multiple stabilizing bars 402 and can only move along a fixed horizontal direction. Therefore, it will move to one side under the drive of the screw rod 404. The screw rod 404 drives multiple mounting bars 306 to move synchronously. The mounting bars 306 drive the extension columns 305 to move through the driving plate 307, and then the fixing plate 303 will be driven to move upward along the limiting groove 302. Then the heat pipe body 304 will no longer be restricted and can be easily removed. Moreover, since the moving direction of the connecting frame 403 is perpendicular to the direction of the centrifugal force when the rotor body 1 is running, the operation of the rotor body 1 will not drive the position of the connecting frame 403 to change, so that the state of the heat pipe body 304 is sufficiently stable.
[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
