Abstract
Description
Technical Field
[0001] This invention relates to the field of motor technology, and more specifically to a motor with heat dissipation function. Background Technology
[0002] As a core power unit in industrial automation, new energy equipment, and home appliances, the reliability and lifespan of electric motors directly depend on the control level of their operating temperature. When a motor is powered on, the hysteresis loss, eddy current loss of the stator core, and Joule loss of the stator coils generate a large amount of heat. If this heat cannot be dissipated in time, it will lead to accelerated aging of the coil insulation layer and irreversible demagnetization of the permanent magnets. In severe cases, it can cause major malfunctions such as winding short circuits and motor burnout. This is especially true for external rotor motors, where the stator assembly is enclosed inside the rotor housing, making it difficult to dissipate heat through natural convection. The internal temperature rise problem is even more pronounced, significantly limiting the power density improvement and long-term continuous operation capability of external rotor motors.
[0003] Currently, the industry mainly uses single air cooling or water cooling technology solutions for motor heat dissipation. Single air cooling usually involves adding a centrifugal fan or axial fan to the rotor shaft to drive airflow, which has the disadvantages of small air volume, insufficient air pressure and low heat dissipation efficiency, and can only meet the heat dissipation needs of small power motors. Traditional water cooling systems require independent configuration of water pumps, water tanks, pipelines and control valve groups, which not only significantly increases the overall size and weight of the motor, but also requires additional electrical energy to drive the water pump, increasing system energy consumption and operation and maintenance costs.

[0018] The present invention will be further described in conjunction with the following embodiments.
[0019] Depend on Figures 1 to 8 As can be seen, the motor with heat dissipation function described in this embodiment includes a stator base 1, a rotor base 2, and a rotating shaft 3; the rotating shaft 3 is rotatably disposed inside the stator base 1; the rotor base 2 is rotatably disposed outside the stator base 1; the rotor base 2 is connected to the rotating shaft 3. The stator base 1 is rotatably provided with an air-cooled annular shell 4; the air-cooled annular shell 4 is connected to the rotor base 2; the air-cooled annular shell 4 is provided with an air-cooled annular cavity; an air-cooled annular piston 5 is movably provided in the air-cooled annular cavity; The stator base 1 is provided with a water-cooled heat dissipation pipe; the stator base 1 is provided with a water-cooled annular shell 6; the water-cooled annular shell 6 is provided with a water-cooled annular cavity; a water-cooled annular piston 7 is movably disposed in the water-cooled annular cavity; the water-cooled heat dissipation pipe is connected to the water-cooled annular cavity. The motor with heat dissipation function also includes a triggering component for driving the water-cooled annular piston 7 and the air-cooled annular piston 5.
[0020] Specifically, in the motor with heat dissipation function described in this embodiment, when the motor is powered on, the rotor seat 2 drives the rotating shaft 3 to rotate synchronously, and at the same time drives the air-cooled annular shell 4 to rotate together with the rotor seat 2. The trigger component converts the rotational motion of the air-cooled annular shell 4 into the axial reciprocating motion of the air-cooled annular piston 5 and the water-cooled annular piston 7. The reciprocating motion of the air-cooled annular piston 5 drives the air to form a forced circulation in the air-cooled annular cavity, which dissipates heat from the stator core 11 and external heat-generating components such as coils. The reciprocating motion of the water-cooled annular piston 7 drives the coolant to form a forced circulation between the water-cooled annular cavity and the water-cooled heat dissipation pipe, thereby absorbing the heat accumulated inside the stator seat 1. This embodiment integrates the air-cooled circulation heat dissipation system with the water-cooled circulation heat dissipation system and utilizes the power of the motor's own rotor base 2 for drive, eliminating the need for additional independent power components such as fans and water pumps. This effectively improves heat dissipation efficiency while reducing system energy consumption and failure rate.
[0021] This embodiment describes a motor with a heat dissipation function, in which the stator base 1, rotor base 2, rotating shaft 3, air-cooled annular shell 4, air-cooled annular cavity, air-cooled annular piston 5, water-cooled annular shell 6, water-cooled annular cavity, and water-cooled annular piston 7 are coaxially arranged. This arrangement ensures that when the rotor base 2 drives the air-cooled annular shell 4 to rotate, the force is uniform, with no radial eccentric load. During axial reciprocating motion, the air-cooled annular piston 5 and water-cooled annular piston 7 maintain a coaxial, sealed fit with the air-cooled annular cavity and water-cooled annular cavity. Furthermore, this effectively reduces vibration and noise during motor operation, improving the overall reliability and service life of the heat dissipation system.
[0022] In this embodiment, a motor with heat dissipation function is provided, wherein the air-cooled annular piston 5 is axially sealed and movable in the air-cooled annular cavity; the air-cooled annular piston 5 divides the air-cooled annular cavity into an air inlet cavity 41 and an air outlet cavity 42; the air-cooled annular shell 4 is provided with an air inlet communicating with the air inlet cavity 41; and the air-cooled annular shell 4 is provided with an air outlet communicating with the air outlet cavity 42.
[0023] Specifically, when the air-cooled annular piston 5 performs a sealed reciprocating motion along the axial direction, the volumes of the air inlet chamber 41 and the air outlet chamber 42 change synchronously in opposite directions. When the air-cooled annular piston 5 moves downward, the volume of the air outlet chamber 42 decreases, and the air inside the air outlet chamber 42 is compressed and discharged directionally through the air outlet, forming a high-speed cooling airflow. When the air-cooled annular piston 5 moves upward, the volume of the air inlet chamber 41 decreases, and the air inside the air inlet chamber 41 is forced into the air outlet chamber 42, serving as a reserve air source for the next exhaust. In this embodiment, through the continuous reciprocating motion of the air-cooled annular piston 5, a continuous forced convection airflow can be generated without an additional fan, effectively increasing the airflow speed on the motor surface and accelerating the heat dissipation speed of the stator surface.
[0024] The motor with heat dissipation function described in this embodiment has an air inlet valve 51 that opens into the air inlet cavity 41; an air outlet valve 52 that opens outward from the air outlet cavity 42; a ventilation port that is provided through the air-cooled annular piston 5; and a ventilation valve 53 that opens into the air outlet cavity 42.
[0025] Specifically, when the air-cooled annular piston 5 moves downward, the volume of the air inlet chamber 41 increases, creating a negative pressure. The air inlet valve 51 automatically opens inward, and cold air from the outside is drawn into the air inlet chamber 41. At the same time, the volume of the air outlet chamber 42 decreases, causing the internal pressure to increase. The air outlet valve 52 automatically opens outward, and the air is forced out of the air outlet chamber 42. At this time, the ventilation valve 53 remains closed because the pressure on the side of the air outlet chamber 42 is greater than that on the side of the air inlet chamber 41, preventing airflow backflow. When the air-cooled annular piston 5 moves upward, the volume of the air inlet chamber 41 decreases and the internal pressure increases. The air inlet valve 51 automatically closes, and the ventilation valve 53 automatically opens towards the side of the air outlet chamber 42. The cold air in the air inlet chamber 41 is forced into the air outlet chamber 42. At the same time, the volume of the air outlet chamber 42 increases, creating a negative pressure. The air outlet valve 52 automatically closes, preventing hot air from flowing back in.
[0026] This embodiment describes a motor with a heat dissipation function. The stator base 1 has an iron core 11; the iron core 11 is wound with coils; the rotor base 2 has magnets 21; the air-cooled annular shell 4 is located on top of the iron core 11; and the air outlet is directly opposite the iron core 11. Specifically, the air-cooled annular shell 4 is integrated on top of the iron core 11, and the air outlet is directly opposite the iron core 11 and the wound coils. The high-speed cooling airflow discharged from the air outlet directly washes over the surface of the stator's iron core 11 and the coils, quickly removing heat from the iron core 11 and the coils; this achieves directional heat dissipation and prevents heat accumulation inside the iron core 11 and the coils.
[0027] In this embodiment, a motor with heat dissipation function is described. The water-cooled annular piston 7 is axially sealed and slidably disposed in the water-cooled annular cavity. The water-cooled annular piston 7 divides the water-cooled annular cavity into an inlet cavity 61 and an outlet cavity 62. The water-cooled heat dissipation pipe includes an annular inlet pipe 81 and an annular outlet pipe 82. The annular inlet pipe 81 is connected to the inlet cavity 61. The annular outlet pipe 82 is connected to the outlet cavity 62. The annular inlet pipe 81 and the annular outlet pipe 82 are connected.
[0028] Specifically, when the water-cooled annular piston 7 performs a sealed reciprocating motion along the axial direction, the volumes of the inlet chamber 61 and the outlet chamber 62 change synchronously in opposite directions. When the water-cooled annular piston 7 moves downward, the volume of the outlet chamber 62 decreases, and the low-temperature coolant inside the outlet chamber 62 is forced into the annular outlet pipe 82, flows through the U-shaped pipe 83 inside the stator seat 1, absorbs the heat conducted inside the stator, and becomes high-temperature coolant, which then flows into the annular inlet pipe 81 and the inlet chamber 61. When the water-cooled annular piston 7 moves upward, the volume of the inlet chamber 61 decreases, and the coolant inside the inlet chamber 61 is forced into the outlet chamber 62, completing one coolant cycle. In this embodiment, the coolant can be forced to flow inside the stator without the need for an additional water pump, directly carrying away the heat inside the stator.
[0029] In this embodiment, a motor with heat dissipation function is provided, wherein an inlet valve 71 that opens into the inlet chamber 61 is provided between the annular inlet pipe 81 and the inlet chamber 61; an outlet valve 72 that opens into the annular outlet pipe 82 is provided between the annular outlet pipe 82 and the outlet chamber 62; a water-cooled annular piston 7 is provided with a water inlet; and a water valve 73 that opens into the outlet chamber 62 is provided at the water inlet.
[0030] Specifically, when the water-cooled annular piston 7 moves downward, the volume of the inlet chamber 61 increases, creating a negative pressure. The inlet valve 71 automatically opens inward, and the high-temperature coolant that has absorbed the stator heat in the annular inlet pipe 81 is drawn into the inlet chamber 61. At the same time, the volume of the outlet chamber 62 decreases and the internal pressure increases. The outlet valve 72 automatically opens towards the annular outlet pipe 82, and the low-temperature coolant in the outlet chamber 62 is forced into the annular outlet pipe 82. At this time, the water valve 73 remains closed because the pressure on the outlet chamber 62 side is greater than that on the inlet chamber 61 side, preventing coolant backflow. When the water-cooled annular piston 7 moves upward, the volume of the inlet chamber 61 decreases and the internal pressure increases. The inlet valve 71 automatically closes, and the water valve 73 automatically opens towards the outlet chamber 62. The high-temperature coolant in the inlet chamber 61 is forced into the outlet chamber 62 for heat dissipation. At the same time, the volume of the outlet chamber 62 increases, creating a negative pressure. The outlet valve 72 automatically closes, preventing the high-temperature coolant in the annular outlet pipe 82 from flowing back into the outlet.
[0031] In this embodiment, a motor with heat dissipation function is provided, wherein a plurality of U-shaped pipes 83 extending in the axial direction are provided between the annular water inlet pipe 81 and the annular water outlet pipe 82; the annular water inlet pipe 81, the annular water outlet pipe 82 and the U-shaped pipes 83 are all embedded in the stator base 1.
[0032] Specifically, after the coolant flows in from the annular inlet pipe 81, it is evenly distributed into multiple axially extending U-shaped pipes 83. During the flow process in the U-shaped pipes 83, it makes full contact with the inner wall of the stator base 1 over a large area, absorbing the heat generated in various parts of the stator, and then collects and flows out through the annular outlet pipe 82. The multiple U-shaped pipes 83 are evenly embedded inside the stator base 1, which greatly increases the heat exchange area between the coolant and the stator base 1, so that the heat in various parts of the stator base 1 can be carried away synchronously and evenly.
[0033] This embodiment describes a motor with a heat dissipation function, in which a water-cooled annular shell 6 is disposed on top of an air-cooled annular shell 4; the water-cooled annular shell 6 has heat dissipation fins 63 on the top of the water inlet cavity 61. The water-cooled annular shell 6 is integrated on the top of the air-cooled annular shell 4, and the heat dissipation fins 63 on the top of the water inlet cavity 61 are in direct contact with the outside air. The heat carried by the high-temperature coolant entering the water inlet cavity 61 can be quickly conducted and dissipated into the outside air through the heat dissipation fins 63; at the same time, the high-speed airflow generated by the rotation of the air-cooled annular shell 4 can further accelerate the airflow on the surface of the heat dissipation fins 63, improve the heat exchange efficiency of the heat dissipation fins 63, and ensure that the coolant is sufficiently cooled before entering the water outlet cavity 62.
[0034] In this embodiment, a motor with heat dissipation function is provided, wherein a connecting rod 91 is provided between the air-cooled annular piston 5 and the water-cooled annular piston 7; the triggering assembly includes a guide rod 92 connected to the water-cooled annular piston 7 and an annular guide groove provided in the air-cooled annular shell 4; the annular guide groove is coaxially arranged with the air-cooled annular shell 4. The annular guide groove includes a first spiral groove 93, a second spiral groove 94, a third spiral groove 95, and a fourth spiral groove 96 connected end to end in sequence; the spiral direction of the first spiral groove 93 is opposite to that of the second spiral groove 94; the spiral direction of the first spiral groove 93 is opposite to that of the fourth spiral groove 96; and the spiral direction of the first spiral groove 93 is the same as that of the third spiral groove 95.
[0035] Specifically, when the air-cooled annular shell 4 rotates synchronously with the rotor seat 2, the guide rod 92 fixed on the water-cooled annular piston 7 is embedded in the annular guide groove. Since the guide rod 92 can only move up and down axially, when the guide rod 92 moves sequentially along the first spiral groove 93, the second spiral groove 94, the third spiral groove 95, and the fourth spiral groove 96 that are connected end to end, the guide rod 92 will drive the water-cooled annular piston 7 to make continuous axial reciprocating up and down motion because the rotation directions of adjacent spiral grooves are alternately opposite. At the same time, the air-cooled annular piston 5 is driven to make the same reciprocating motion synchronously through the connecting rod 91. This realizes the synchronous linkage operation of the air-cooled circulating heat dissipation system and the water-cooled circulating heat dissipation system. The power comes directly from the rotor seat 2 of the motor, without the need for an additional drive device, and the power transmission is efficient and reliable. Moreover, the heat dissipation power is automatically adjusted with the motor speed. The greater the motor load and the higher the speed, the faster the reciprocating motion frequency of the water-cooled annular piston 7 and the air-cooled annular piston 5, and the greater the air-cooling air volume and water-cooling coolant flow rate. The heat dissipation power is automatically matched with the heat dissipation power of the motor, avoiding the waste of heat dissipation resources.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
