Description

Technical Field

[0001] This utility model belongs to the field of motor technology, and in particular relates to a motor with a cooling cycle. Background Technology

[0002] Conventional motors generate heat during operation primarily through heat conduction and radiation to transfer it to the surrounding medium, thus achieving thermal equilibrium. However, this type of heat dissipation is inefficient, especially in high-temperature, high-power-density applications, where it often fails to meet the motor's heat dissipation requirements, limiting further performance improvements.

[0003] Reference document CN114337113B proposes a stator-rotor hybrid evaporative cooling motor structure. This scheme utilizes the characteristic of the evaporative cooling medium absorbing a large amount of heat during phase change to enhance the cooling effect on key heat-generating parts of the motor (such as the stator and rotor). Although this structure improves heat dissipation capacity to a certain extent, it has a significant drawback: the system lacks a design for effective condensation and recovery of the gaseous cooling medium. During continuous operation, the evaporative cooling medium continuously absorbs heat and vaporizes, causing vapor to accumulate in the internal cavity of the motor and the pressure to gradually increase. Under long-term operation, excessive internal pressure may lead to sealing failure, structural deformation, or even safety issues. At the same time, the inability of the vaporized medium to condense and return in a timely manner also restricts the efficiency and reliability of the evaporative cooling cycle. Utility Model Content This invention provides a cooling cycle motor, which aims to solve the problems mentioned in the background art of existing evaporative cooling motors, such as internal vapor pressure accumulation, ineffective condensation and recovery, leading to sealing failure, structural deformation and reduced cycle reliability.

[0004] To solve the above problems, this utility model is implemented as follows: a cooling cycle motor includes: a base and a motor body fixedly mounted on the base; an evaporative cooling medium disposed in the interlayer between the inner shell and the outer shell of the motor body for heat dissipation of the motor body; a cooling box disposed above the motor body for cooling the vapor of the evaporative cooling medium; connecting pipes all mounted on the motor body for introducing steam into the cooling box, and a set of connecting pipes all connected to the cooling box; and cooling plates installed inside the cooling box for cooling operations inside the cooling box.

[0005] Preferably, a partition is fixedly installed inside the cooling box, which separates the cooling box into a water storage chamber and a cooling chamber. The cooling plate is located above the water storage chamber for cooling the water. Several baffles are fixedly installed inside the cooling chamber to separate the cooling chamber into a serpentine channel. A set of connecting pipes are all connected to the cooling chamber.

[0006] Preferably, a connecting pipe is fixedly installed on one side of the cooling box, and the branch pipes of the connecting pipe are respectively connected to the cavities of the baffles. A water pump is fixedly installed in the water storage cavity, and the drain end of the water pump is fixedly connected to the connecting pipe.

[0007] Preferably, a temperature sensor for monitoring the temperature inside the cooling chamber is fixedly installed inside the cooling chamber, a stirring blade for uniform cooling is rotatably installed on one side of the water storage chamber, and a servo motor for driving the stirring blade to rotate is fixedly installed on one side of the cooling box, with the output shaft of the servo motor coupling fixedly connected to the rotating shaft of the stirring blade.

[0008] Preferably, the cooling chamber is provided with a heat insulation layer, the heat dissipation end of the cooling chip is equipped with a heat dissipation fin, a bracket is fixedly installed on the top of the cooling box, and a cooling fan for assisting the heat dissipation of the heat dissipation fin is installed on the bracket.

[0009] Preferably, the bottom of the cooling tank is provided with a drain port, which is located between the two baffles for discharging the evaporated cooling medium after cooling. A drain box is fixedly installed at the bottom of the cooling tank, which is connected to the drain port. The bottom of the inner wall of the drain box is inclined, and the drain pipe of the drain box is fixedly connected to the connecting pipe.

[0010] Preferably, a sealing plate for sealing the drain port is rotatably installed at the bottom of the cooling tank, and a support plate is fixedly installed at the bottom of the cooling cavity. A reset spring for resetting the sealing plate is installed on the support plate. The reset spring passes through the drain port, and the bottom end of the reset spring is fixedly connected to the sealing plate.

[0011] Compared with related technologies, the motor with cooling cycle provided by this utility model has the following beneficial effects: Compared with existing technologies, the cooling cycle motor provided by this solution provides an external, forced condensation and recovery site for the vaporized cooling medium by setting up a cooling box and refrigeration plates. After the vapor enters the cooling box through the connecting pipe, it is actively cooled and liquefied, and its volume is drastically reduced. This fundamentally avoids the problem of unlimited pressure rise caused by the continuous vaporization of the evaporating cooling medium in the internal cavity of the motor. This eliminates the risk of seal failure, structural deformation or even explosion caused by excessive pressure, and greatly improves the safety and reliability of the motor in long-term operation.

[0012] In summary, the cooling cycle motor of this invention achieves automatic circulation and reuse of the cooling medium through four core steps: evaporation heat absorption, steam transportation, forced condensation, and medium reflux. This significantly improves the motor's heat dissipation capacity and power density, and ensures the reliability and stability of the motor's long-term operation. Attached Figure Description

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0016] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0017] This utility model embodiment provides a motor with a cooling cycle, such as Figure 1-4As shown, the motor for cooling circulation includes: a base 1 and a motor body 2 fixedly mounted on the base 1; an evaporative cooling medium 5 disposed in the interlayer between the inner shell 3 and the outer shell 4 of the motor body 2 for heat dissipation of the motor body 2; a cooling box 6 disposed above the motor body 2 for cooling the vapor of the evaporative cooling medium 5; connecting pipes 21, all mounted on the motor body 2 for introducing steam into the cooling box 6, and a set of connecting pipes 21 all connected to the cooling box 6; and cooling plates 7 installed inside the cooling box 6 for cooling the contents of the cooling box 6.

[0018] In this embodiment, the motor body 2 generates a large amount of heat during operation. This heat is transferred to the liquid evaporative cooling medium 5 located in the interlayer between the inner shell 3 and the outer shell 4 through heat conduction. After absorbing the heat, the medium undergoes a vaporization phase change, changing from a liquid state to a gaseous state. This absorbs and carries away a large amount of heat generated by the motor body 2, effectively controlling the temperature rise of the motor body 2. The vaporized cooling medium vapor is introduced into the cooling chamber of the cooling box 6 through a set of connecting pipes 21 connected to the cooling box 6 under the action of pressure difference, completing the transfer of heat from the inside of the motor body 2 to the external cooling unit. The inside of the cooling box 6 is divided into an independent water storage chamber and a cooling chamber by a partition 8. The cooling plate 7 is located above the water storage chamber. Its cooling end continuously cools the water in the water storage chamber to obtain a low-temperature cold source. Driven by the water pump 11, the cold water in the water storage chamber is pumped into the serpentine channel formed by several baffles 9 through the connecting pipe 10 and its branch pipe. The low-temperature cold water flows in the cavity channel of the baffle 9, which greatly increases the heat exchange area and residence time, thereby efficiently and uniformly cooling and condensing the steam filling the cooling chamber. High-temperature steam undergoes thorough heat exchange with the low-temperature serpentine cavity wall, causing the temperature to drop rapidly and condense back into a liquid state. The condensed liquid cooling medium accumulates at the bottom of the cooling cavity under gravity. The condensate flows into the drain box 20 through the drain port 19 at the bottom of the cooling cavity. The bottom inner wall of the drain box 20 is designed with an inclination to facilitate liquid collection. It is connected to the connecting pipe 21 through its drain pipe, allowing the condensed liquid cooling medium to flow smoothly back into the interlayer of the motor body 2, forming a complete, closed-loop, lossless cooling medium circulation. By setting up the cooling box 6 and the cooling plate 7, an external, forced condensation and recovery site is provided for the vaporized cooling medium. After the steam enters the cooling box 6 through the connecting pipe 21, it is actively cooled and liquefied, and its volume is drastically reduced. This fundamentally avoids the problem of unlimited pressure rise caused by the continuous vaporization of the evaporating cooling medium 5 in the internal cavity of the motor. This eliminates the risk of sealing failure, structural deformation, or even explosion caused by excessive pressure, greatly improving the safety and reliability of the motor during long-term operation.

[0019] In a further preferred embodiment of this utility model, a partition 8 is fixedly installed inside the cooling box 6, the partition 8 separates the cooling box 6 to form a water storage chamber and a cooling chamber, the cooling chip 7 is located above the water storage chamber for cooling the water, and a plurality of baffles 9 are fixedly installed inside the cooling chamber to separate the cooling chamber to form a serpentine channel, and a set of connecting pipes 21 are all connected to the cooling chamber.

[0020] In this embodiment, the partition 8 inside the cooling box 6 divides it into a water storage chamber and a cooling chamber, achieving medium isolation and functional zoning. The cooling plate 7 focuses on cooling the water in the water storage chamber. After the steam enters the cooling chamber through the connecting pipe 21, it is guided and restricted by several baffles 9 to flow in the meandering serpentine channel. This greatly extends the residence time and flow path of the steam, allowing it to have a more thorough and uniform heat exchange with the low-temperature chamber wall, thereby significantly improving the condensation efficiency and cooling capacity.

[0021] In a further preferred embodiment of the present invention, a connecting pipe 10 is fixedly installed on one side of the cooling box 6, and the branch pipes of the connecting pipe 10 are respectively connected to the cavities of a plurality of baffles 9. A water pump 11 is fixedly installed in the water storage cavity, and the drain end of the water pump 11 is fixedly connected to the connecting pipe 10.

[0022] In this embodiment, the low-temperature water cooled by the cooling chip 7 in the water storage chamber is powered by the water pump 11 and forced into the baffle 9 cavity of the cooling chamber through the connecting pipe 10 and its branch pipe. The low-temperature water flows in the cavity, directly and efficiently cooling the wall surface that forms the serpentine cavity, thereby enhancing the condensation effect on the steam in the cavity. This system realizes the on-demand and active distribution of cooling capacity, overcomes the limitations of simply relying on the surface cooling of the cooling chip, and has stronger cooling intensity and controllability.

[0023] In a further preferred embodiment of the present invention, a temperature sensor 12 for monitoring the temperature inside the cooling chamber is fixedly installed inside the cooling chamber, a stirring blade 13 for uniform cooling is rotatably installed on one side of the water storage chamber, and a servo motor 14 for driving the stirring blade 13 to rotate is fixedly installed on one side of the cooling box 6, and the output shaft of the coupling of the servo motor 14 is fixedly connected to the rotating shaft of the stirring blade 13.

[0024] In this embodiment, the temperature sensor 12 monitors the temperature inside the cooling chamber in real time, providing a key feedback signal to the system. This enables the control system to intelligently adjust the power of the cooling chip 7 or the water pump 11 according to the actual heat load, achieving precise temperature control and energy saving. The servo motor 14 drives the stirring blade 13 to rotate, stirring the water in the water storage chamber and eliminating the water temperature stratification phenomenon, i.e., cold water sinks and hot water floats. This ensures the uniformity of the water temperature in the water storage chamber, thereby allowing the cooling capacity of the cooling chip 7 to be evenly distributed, avoiding local overcooling or a decrease in cooling efficiency.

[0025] In a further preferred embodiment of the present invention, a heat insulation layer 15 is provided inside the cooling cavity, a heat dissipation fin 16 is installed on the heat dissipation end of the cooling chip 7, a bracket 17 is fixedly installed on the top of the cooling box 6, and a cooling fan 18 for assisting the heat dissipation of the heat dissipation fin 16 is installed on the bracket 17.

[0026] In this embodiment, the insulation layer 15 provided in the cooling cavity effectively blocks the transfer of external environmental heat into the cavity, while preventing the loss of internal cooling capacity. The cooling capacity is concentrated for steam condensation, which significantly improves the energy utilization efficiency of the system. When the heat dissipation end of the cooling chip 7 is working, it generates a large amount of heat. The heat dissipation fins 16 installed on it increase the heat dissipation area and are forced to be cooled by the cooling fan 18, ensuring that the heat at the hot end of the cooling chip can be quickly dissipated into the environment, thereby ensuring the cooling efficiency and long-term working stability of the cooling chip 7.

[0027] In a further preferred embodiment of this utility model, a drain port 19 is provided at the bottom of the cooling box 6. The drain port 19 is located between the two baffles 9 and is used to discharge the evaporative cooling medium 5 after cooling. A drain box 20 is fixedly installed at the bottom of the cooling box 6. The drain box 20 is connected to the drain port 19. The bottom of the inner wall of the drain box 20 is inclined, and the drain pipe of the drain box 20 is fixedly connected to the connecting pipe 21.

[0028] In this embodiment, the liquefied cooling medium gathers at the bottom of the cooling chamber and flows into the drain box 20 through the drain port 19. The inclined design of the bottom inner wall of the drain box 20 facilitates the natural convergence of liquid to the drain pipe, ensuring smooth drainage without residue. The drain pipe is connected to the connecting pipe 21, so that the condensate can reliably flow back to the motor, completing the closed-loop circulation of the medium.

[0029] In a further preferred embodiment of the present invention, a sealing plate 22 for sealing the drain port 19 is rotatably installed at the bottom of the cooling box 6, and a support plate 23 is fixedly installed at the bottom of the cooling cavity. A reset spring 24 for resetting the sealing plate 22 is installed on the support plate 23. The reset spring 24 passes through the drain port 19, and the bottom end of the reset spring 24 is fixedly connected to the sealing plate 22.

[0030] In this embodiment, at the bottom of the cooling chamber, the return spring 24 provides elastic force to keep the sealing plate 22 normally closed, sealing the drain port 19. This helps to maintain a sealed environment and a certain pressure in the cooling chamber during the condensation process, which is conducive to the full condensation of steam. When the condensate accumulates to a certain weight, its gravity overcomes the elastic force of the return spring 24, and the sealing plate 22 is pressed down to open, realizing the drainage. After drainage, the weight is reduced, and the sealing plate 22 closes again under the action of the spring. This structure forms an automatic one-way valve controlled by the gravity of the liquid, realizing intermittent automatic drainage, while avoiding the problem of direct leakage of steam before condensation.

[0031] In summary, compared with related technologies, the motor of this cooling cycle achieves automatic circulation and reuse of the cooling medium through four core steps: evaporation heat absorption, steam transportation, forced condensation, and medium reflux. This significantly improves the motor's heat dissipation capacity and power density, and ensures the reliability and stability of the motor's long-term operation.
