[0003] Most of these devices on the market currently rely on natural heat dissipation from the outer casing and do not have dedicated liquid cooling channels. Due to the high transmission power, a large amount of heat is generated during operation due to conductive contact resistance and mechanical friction, with internal temperatures reaching hundreds of degrees Celsius.

[0004] Natural heat dissipation is insufficient to meet the demand. Heat accumulation not only accelerates the aging of components and shortens their lifespan, but may also lead to malfunctions such as decreased insulation performance and reduced conductivity, and even cause short circuits and fires, seriously affecting the safety and stability of the equipment.

[0005] Therefore, how to provide an electrical energy rotation transmission system with liquid cooling function is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0034] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0035] Example 1

[0036] A specific embodiment of this utility model is as follows: Figure 1 and Figure 2 As shown, an electric power rotation transmission system with liquid cooling heat dissipation function is disclosed, including an electric power rotation transmission device 1 and a cooling water circulation device 2.

[0037] like Figure 2 As shown, the power rotation transmission system includes an upper housing 11, a lower housing 12, an upper rotating part 13, a lower rotating part 14, and conductive components; the upper housing 11 is disposed on the upper rotating part 13; the lower housing 12 is disposed on the lower rotating part 14; during the relative rotation of the upper rotating part 13 and the lower rotating part 14, the conductive components make elastic contact to transmit power.

[0038] The upper housing 11 has an upper cooling path 1101, and the lower housing 12 has a lower cooling path 1201. The upper cooling path 1101 and the lower cooling path 1201 are connected to form a liquid cooling channel.

[0039] The cooling water circulation device 2 provides cooling water to the liquid cooling channel, and the cooling water cools and dissipates heat from the conductive components.

[0040] This invention forms a connected liquid cooling channel by opening an upper cooling path 1101 and a lower cooling path 1201 in the upper shell 11 and the lower shell 12 respectively. With the help of the cooling water circulation device 2 to provide cooling water, it can achieve efficient liquid cooling of conductive components. Compared with the traditional method of relying solely on the natural heat dissipation of the outer shell, it significantly improves the heat dissipation efficiency, avoids excessive internal temperature, thereby slowing down the aging of components and extending the service life of the device.

[0041] The upper housing 11 provides structural support and fixation for the upper rotating part 13 of the power rotation transmission device 1, and the lower housing 12 provides structural support and fixation for the lower rotating part 14 of the power rotation transmission device 1. The lower housing 12 has a ring of mounting holes with a diameter of 10mm around its periphery for fixed connection with external equipment.

[0042] Furthermore, the lower end of the upper housing 11 is sealed against the upper end of the lower housing 12.

[0043] When the upper rotating part 13 and the lower rotating part 14 rotate relative to each other, in order to prevent cooling water from overflowing from the liquid cooling channel, an outer sealing ring 16 and an inner sealing ring 17 are provided on the end faces of the upper housing 11 and the lower housing 12 that are in contact with each other. The outer sealing ring 16 and the inner sealing ring 17 are arranged in a concentric ring shape. The outer sealing ring 16 and the inner sealing ring 17 seal the gap between the upper housing 11 and the lower housing 12 to block the leakage of cooling water.

[0044] Furthermore, the cooling water circulation device 2 continuously supplies cooling water to the liquid cooling channel, forming a cooling water circulation path with the liquid cooling channel and the cooling water circulation device 2. A first opening 1102 is provided on the upper housing 11, communicating with the upper cooling path 1101. A second opening 1202 is provided on the lower housing 12, communicating with the lower cooling path 1201. The output end of the cooling water circulation device 2 is connected to the first opening 1102, and the input end of the cooling water circulation device 2 is connected to the second opening 1202.

[0045] The cooling water circulation device 2 forms a closed loop with the liquid cooling channel. The cooling water output from the cooling water circulation device 2 is input into the liquid cooling channel through the first opening 1102. After the cooling water completes the task of cooling the conductive components, it flows out through the second opening 1202 and flows back to the cooling water circulation device 2 for cooling and reuse.

[0046] Furthermore, the cooling water circulation device 2 includes an evaporator 21, a condenser 22, and a cooling tower 23. The evaporator 21 efficiently absorbs the heat carried by the circulating water in the liquid cooling channel, achieving initial cooling. The condenser 22 quickly transfers the heat from the high-temperature medium discharged by the evaporator 21 to the cooling medium, completing a secondary heat transfer. The cooling tower 23, through heat exchange with the air, dissipates the heat discharged by the condenser 22 to the outside, ensuring that the cooling medium temperature returns to a suitable range before re-entering the circulation. The three components have clear divisions of labor and are closely integrated, significantly improving the cooling efficiency of the cooling water and quickly responding to the heat generation demands during peak equipment operation. The stepped heat treatment reduces the load pressure on individual components, extending the overall service life of the device. The clearer heat transfer path facilitates precise control of the operating status of each component according to actual cooling needs, further reducing energy consumption and providing multiple guarantees for the stable and efficient operation of the entire circulation system.

[0047] Furthermore, the upper rotating part 13 includes a spindle 1301, and the upper housing 11 is fixed to the spindle 1301.

[0048] Furthermore, the lower rotating part 14 includes a brush holder 1401, and the lower housing 12 is fixed to the brush holder 1401.

[0049] Furthermore, the conductive components include a conductive ring 15 and brush bristles; a cable is welded to the inner ring of the conductive ring 15, and the other end of the cable is welded to the electrical socket of the upper rotating part 13 of the power transmission device 1; the outer surface of the conductive ring 15 has a high degree of smoothness and elastically contacts the brush bristles to complete the power transmission during relative rotation; the conductive ring 15 is pressed by a bearing retainer ring to maintain relative fixation. The brush bristles are made of a highly elastic, wear-resistant, conductive precious metal, with one end welded to a conductive welding plate and the other end elastically overlapping the outer surface of the conductive ring 15, forming a power transmission channel between the brush bristles and the conductive ring 15.

[0050] The conductive ring 15 is disposed on the upper rotating part 13; the upper end of the brush bristles is disposed on the lower rotating part 14, the lower end of the brush bristles is disposed on the brush holder 1401, and the upper end of the brush bristles is elastically attached to the conductive ring 15.

[0051] During the relative rotation of the upper rotating part 13 and the lower rotating part 14, the upper ends of the brush bristles elastically overlap the outer surface of the conductive ring 15, forming an electrical energy transmission channel.

[0052] The brush holder 1401 is fixed to the power brush plate, enabling synchronous rotation of the brush filaments and the brush holder 1401. Bearings are connected to both ends of the brush holder 1401, and the brush holder 1401 rotates relative to the spindle 1301. The power brush plate is made of electrically insulating material and has threaded holes on its surface. Screws are used to fix the power brush plate to the conductive welding plate. The conductive welding plate has angled holes on its surface; after the brush filaments are inserted into these holes, they are fixed by welding.

[0053] Furthermore, the upper rotating part 13 also includes an insulating post 1302, an insulating ring 1303, a bottom insulating ring 1304, and a first bearing 1305. The insulating post 1302 is made of electrically insulating material and is fixedly bonded to the spindle 1301, which serves as the mounting reference for the insulating ring 1303 and the conductive ring 15. The bearing retainer is fixed to the spindle 1301, with its outer ring and the inner ring of the bearing having an interference fit. The spindle 1301, the insulating ring 1303, the conductive ring 15, and the bearing retainer are all fixed together to ensure synchronous rotation. The inner ring of the first bearing 1305 has an interference fit with the spindle 1301, and its outer ring has an interference fit with the brush holder 1401, enabling stable and smooth relative rotational movement with the spindle 1301.

[0054] Furthermore, the lower rotating part 14 includes a power brush plate, a conductive welding plate, a sealing plate, a second bearing 1402, and a bearing retaining ring. The sealing plate is positioned so that the installation of the brush bristles can be visually observed to prevent bending or unreliable contact during installation. After ensuring the brush bristles are in place, screws are used to fix them to the brush holder 1401 to prevent external dust and moisture from entering the electrical energy rotation transmission device 1. The inner ring of the second bearing 1402 is interference-fitted with the bearing retaining ring, and the outer ring of the second bearing 1402 is interference-fitted with the brush holder 1401, so that the outer ring of the brush holder 1401 and the inner ring of the spindle 1301 rotate stably and smoothly relative to each other.

[0055] Furthermore, the power rotation transmission device 1 also includes an upper cover plate 18 and a lower cover plate 19.

[0056] The upper cover plate 18 serves as a seal for the upper rotating part 13 and also as a support structure for the electrical socket of the upper rotating part 13. The upper cover plate 18 is fixed to the upper housing 11 by screws. The lower cover plate 19 serves as a seal for the lower rotating part 14 and also as a support structure for the electrical socket of the lower rotating part 14. The lower cover plate 19 is fixed to the lower housing 12 by screws.

[0057] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
