Description

Technical Field

[0001] This invention relates to the field of high-speed motor technology, specifically a high-speed motor assembly with self-circulating cooling function. Background Technology

[0002] High-speed motors are an important component of industrial automation and intelligence, and are widely used in machinery manufacturing, automobiles, aerospace and other fields. High-speed motors generate a lot of heat during operation, and if this heat is not effectively controlled and discharged, it will have an adverse effect on the performance and life of the motor.

[0003] Traditional motor cooling methods mainly rely on external cooling systems, such as fans and heat sinks. These methods are often limited by cooling efficiency. Moreover, for high-speed motors, due to their high speed, they generate more and faster heat, and traditional cooling methods can no longer meet their cooling needs. With the development of technology, liquid cooling technology has begun to be applied to the heat dissipation of high-speed motors. It uses circulating coolant to remove the heat inside the high-speed motor. However, existing liquid cooling methods for high-speed motors have the following problems: the heat absorption pipes used for circulating coolant are mostly reciprocating meandering (similar to the heat exchange tubes inside a heat exchanger). The flow path of the coolant in the heat absorption pipes is relatively long. This results in the coolant having a significant heat absorption effect when it first enters the heat absorption pipe. However, as it flows further in, the coolant temperature increases due to the heat absorption at the beginning, and the heat absorption effect is greatly reduced. This leads to uneven cooling inside the high-speed motor and the phenomenon of localized overheating.

[0004] Therefore, the present invention proposes a high-speed motor assembly with self-circulating cooling function to solve the above problems. Summary of the Invention

[0005] The purpose of embodiments of the present invention is to provide a high-speed motor assembly with self-circulating cooling function to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-speed motor assembly with self-circulating cooling function includes a high-speed motor body and a coolant reservoir disposed on the high-speed motor body and filled with coolant. The high-speed motor body housing has multiple horizontally equidistantly arranged U-shaped heat absorbers, each spanning the internal components of the high-speed motor body to absorb heat emitted during operation. Each U-shaped heat absorber has a coolant circulation channel inside. A circulation pump is located at the bottom of the reservoir, with a diverter pipe at the pump's outlet. The diverter pipe and the midpoint of the top of each U-shaped heat absorber have connected inlet pipes. Each U-shaped heat absorber has outlet pipes at its lower ends on both sides, with the end of each outlet pipe furthest from the U-shaped heat absorber located inside the reservoir. The reservoir also has a cooling mechanism for cooling the returning coolant.

[0008] In one optional embodiment: the coolant mechanism includes a heat-absorbing block fixed inside the storage tank, multiple uniformly spaced and through-type heat-conducting columns on the heat-absorbing block, and a rotating shaft rotatably disposed inside the storage tank and below the heat-absorbing block. One end of each outlet pipe inside the storage tank is located above the heat-absorbing block and is equipped with an atomizing nozzle. The heat-absorbing block is uniformly provided with a tapered liquid-draining channel that is wider at the top and narrower at the bottom. Both ends of each heat-conducting column are located outside the storage tank and are equipped with heat dissipation fins. The storage tank has multiple rotatable fan blades arranged in a row on both sides near the heat dissipation fins. Both ends of the rotating shaft are fixedly connected to any one of the drive ends of the fan blades arranged on both sides of the storage tank. A first transmission component is provided between the multiple fan blades located on the same side of the storage tank. The heat-absorbing block has a collecting cavity communicating with the tapered liquid-draining channel, and a liquid-draining pipe is provided on the bottom side of the heat-absorbing block. The rotating shaft is equipped with multiple circumferentially uniformly arranged driven blades for being impacted by the falling coolant and thus driving the rotating shaft to rotate.

[0009] In one alternative: each of the U-shaped heat absorbers has a liquid flow channel inside it, which is provided with a rope that is arranged along the direction of the liquid flow channel and can move back and forth. Multiple fixed cylindrical members are evenly threaded on the rope, and multiple stirring columns are evenly arranged on each cylindrical member in the circumferential direction.

[0010] In one alternative: tension springs are provided between both ends of the rope and the end of the liquid flow channel; a rotatable rotating rod is provided inside the housing of the high-speed motor body; the rotating rod can rotatably pass through all the U-shaped heat absorbers; and a fixed cam is provided on the rod segment inside each U-shaped heat absorber; a groove adapted to the rope is provided on the side of the cam; and a section of the rope is locked in the groove.

[0011] In one alternative: a second transmission component is provided between the rotating rod and the rotating shaft.

[0012] In one alternative: the inner wall of the fluid channel is provided with a plurality of limiting protrusions for restricting the rope, and the rope passes through all the limiting protrusions.

[0013] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows:

[0014] The coolant in the storage tank is pumped by a circulating pump through the liquid flow channels inside multiple U-shaped heat absorption components, and then returned to the storage tank through the outlet pipe to form a closed circulation of coolant. After entering the liquid flow channel through the inlet pipe, the coolant is split to both sides of the liquid flow channel, and only half of the liquid flow channel flows. The heat absorption flow path is short, so that the coolant is in a highly efficient heat absorption state throughout the entire heat absorption flow path, thereby achieving uniform cooling of the high-speed motor body.

[0028] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] Please see Figures 1-3 A high-speed motor assembly with self-circulating cooling function includes a high-speed motor body and a coolant reservoir 1 disposed on the high-speed motor body and filled with coolant. The high-speed motor body housing has multiple horizontally equidistant U-shaped heat absorbers 15, each spanning the internal components of the high-speed motor body to absorb heat emitted during operation. Each U-shaped heat absorber 15 has a coolant circulation channel 18 inside. A circulation pump 13 is located at the bottom inside the reservoir 1, with a diversion pipe 14 at the outlet end of the circulation pump 13. The diversion pipe 14 and the midpoint of the top of each U-shaped heat absorber 15 are connected by inlet pipes 27. Each U-shaped heat absorber 15 has outlet pipes 17 at its lower ends on both sides, with the end of each outlet pipe 17 away from the U-shaped heat absorber 15 located inside the reservoir 1. The reservoir 1 also has a cooling mechanism for cooling the returning coolant.

[0030] The coolant in the storage tank 1 is pumped by the circulating pump 13 through the liquid flow channels 18 provided inside the multiple U-shaped heat absorbers 15, and then returned to the storage tank 1 through the outlet pipe 17 to form a closed circulation of coolant. The heat emitted by the high-speed motor body during operation is absorbed by the multiple horizontally equidistant U-shaped heat absorbers 15, and then conducted to the circulating coolant to be carried away, thereby cooling the high-speed motor body. The returning coolant is cooled by the cooling liquid mechanism to keep the coolant at a low temperature, ensuring the heat absorption effect of the coolant during circulation. After the coolant enters the liquid flow channel 18 through the inlet pipe 27, it is split to both sides of the liquid flow channel 18. Only half of the liquid flow channel 18 is in a short "heat absorption" flow path, so that the coolant is in a highly efficient heat absorption state throughout the "heat absorption" flow path, thereby achieving uniform cooling of the high-speed motor body.

[0031] Please see Figure 1 , Figure 2 , Figures 4-6 In one embodiment of the present invention, the cooling liquid mechanism includes a heat-absorbing block 7 fixedly disposed inside the liquid storage tank 1, multiple uniformly and through-type heat-conducting columns 5 disposed on the heat-absorbing block 7, and a rotating shaft 11 rotatably disposed inside the liquid storage tank 1 and located below the heat-absorbing block 7. One end of each liquid outlet pipe 17 located inside the liquid storage tank 1 is located above the heat-absorbing block 7 and is provided with an atomizing nozzle 6. The heat-absorbing block 7 is uniformly provided with a tapered liquid discharge channel 26 that is wider at the top and narrower at the bottom. Both ends of each heat-conducting column 5 are located outside the liquid storage tank 1 and are provided with heat dissipation fins 2. Multiple rotatable heat-conducting columns are arranged in a row on both sides of the liquid storage tank 1 near the heat dissipation fins 2. The fan blades 3 are fixedly connected at both ends of the rotating shaft 11 to any one of the driving ends of the fan blades 3 arranged on both sides of the liquid storage tank 1. A first transmission component 4 is provided between multiple fan blades 3 located on the same side of the liquid storage tank 1 (the first transmission component 4 includes a synchronous transmission structure composed of several transmission wheels, transmission chains or transmission belts, which is a mature existing technology and will not be described in detail here). The heat absorption block 7 is provided with a collecting cavity 8 that communicates with the conical liquid discharge channel 26, and a liquid discharge pipe 9 is provided on the bottom side of the heat absorption block 7. Multiple circumferentially uniformly arranged driven blades 10 are provided on the rotating shaft 11, which are used to be impacted by the falling coolant and thus drive the rotating shaft 11 to rotate.

[0032] In this embodiment, the coolant returning to the storage tank 1 from the outlet pipe 17 is sprayed out in a mist form under the action of the atomizing nozzle 6 and falls onto the heat absorption block 7. The heat absorption block 7 absorbs the heat in the coolant, and then conducts it to the heat dissipation fins 2 through multiple heat-conducting columns 5, thereby cooling the returned coolant. The mist-like coolant falling on the heat absorption block 7 gathers into a liquid state and flows downward along the conical liquid discharge channel 26. Under the action of the conical liquid discharge channel 26, which is wider at the top and narrower at the bottom, the flow rate of the coolant is accelerated. The coolant flowing down from the conical liquid discharge channel 26 gathers into the collection chamber 8, and finally flows down through the liquid discharge pipe 9 to impact the driven blades 10, thereby driving the rotating shaft 11 to rotate. Under the transmission action of the first transmission member 4, the rotation of the rotating shaft 11 drives the multiple fan blades 3 set on both sides of the storage tank 1 to rotate synchronously, accelerating the airflow around the heat dissipation fins 2 to carry away the heat dissipated by the heat dissipation fins 2.

[0033] Please see Figure 3 , Figures 7-9 In one embodiment of the present invention, each of the U-shaped heat absorbers 15 has a liquid flow channel 18 inside, which is provided with a rope 21 that is arranged along the direction of the liquid flow channel 18 and can move back and forth. Multiple fixed cylindrical members 23 are evenly threaded on the rope 21, and multiple stirring columns 24 are evenly arranged on each cylindrical member 23 in a circumferential direction.

[0034] Tension springs 20 are provided at both ends of the rope 21 and the end of the liquid channel 18. A rotatable rotating rod 16 is provided inside the housing of the high-speed motor body. The rotating rod 16 can rotatably pass through all the U-shaped heat absorbers 15. A fixed cam 19 is provided on the rod segment inside each U-shaped heat absorber 15. The side of the cam 19 is provided with a groove 25 that is adapted to the rope 21. Part of the rope 21 is locked in the groove 25. A second transmission component 12 is provided between the rotating rod 16 and the rotating shaft 11 (the second transmission component 12 includes a synchronous transmission structure composed of several transmission wheels, transmission chains or transmission belts, which is a mature existing technology and will not be described in detail here).

[0035] In this embodiment, the rope 21 is taut under the action of two tension springs 20. Under the transmission action of the second transmission component 12, the rotating shaft 11 rotates and drives the rotating rod 16 to rotate synchronously. The rotating rod 16 drives multiple cams 19 to rotate synchronously. Since part of the rope 21 is stuck in the slot 25, the cam 19 will pull / release the rope 21 in a cycle when it rotates. Under the reset action of the two tension springs 20, the rope 21 moves back and forth, thereby causing each cylindrical part 23 on the rope 21 to move back and forth. This drives the stirring column 24 to continuously stir the coolant to increase the fluidity of the coolant. This makes the coolant near the side wall of the liquid flow channel 18 constantly "renewed" (it should be noted that the coolant near the side wall of the liquid flow channel 18 will first absorb the heat from the U-shaped heat absorber 15. In the case of poor fluidity, this part of the coolant will have a higher temperature, affecting the heat absorption efficiency), thus improving the heat absorption efficiency of the coolant.

[0036] Furthermore, in this embodiment, the inner wall of the liquid flow channel 18 is provided with a plurality of limiting protrusions 22 for limiting the rope 21. The rope 21 passes through all the limiting protrusions 22. The multiple limiting protrusions 22 are used to install the rope 21 and to limit it, so as to prevent the rope 21 from deviating during the pulling / releasing process.

[0037] Furthermore, in this embodiment, the rope 21 is a stainless steel rope.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
