[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0035] This embodiment relates to a circulating liquid cooling heat dissipation motor, the overall structure of which is as follows: Figure 1 As shown, it includes a shell 1, a circulation mechanism 6, a radiator 7, and a wind cover 8.

[0036] Among them, a stator 2 is fixedly arranged in the outer shell 1, a rotor 3 is rotatably arranged in the stator 2, a front end cover 4 and a rear end cover 5 are fixedly arranged at both ends of the outer shell 1, a circulation mechanism 6 is fixedly arranged between the outer shell 1 and the rear end cover 5, a radiator 7 is fixedly arranged on the rear end cover 5, the radiator 7 is connected to the circulation mechanism 6, and a wind cover 8 is fixedly arranged on the rear end cover 5, and the radiator 7 is located in the wind cover 8.

[0037] It is worth mentioning that the installation and connection method of the housing 1, the stator 2 and the rotor 3 is a common motor installation method in the prior art, which will not be repeated here. The front cover 4 and the rear cover 5 are fixed to the housing 1 by screws. The circulation mechanism 6 added between the rear cover 5 and the housing 1 plays a circulation role, circulating the coolant or cooling oil in the housing 1, so as to cool the rotor 3 and the stator 2. The circulation mechanism 6 is connected to the housing 1 to realize the circulation of the coolant and the cooling oil. The radiator 7 is located at the tail of the rear cover 5, and the central axis of the rotor 3 passes through the circulation mechanism 6, which can drive the circulation mechanism 6 and the radiator 7 to work. The wind hood 8 covers the radiator 7 to play a dust-proof role to prevent dust from being adsorbed on the radiator 7, thereby affecting the heat dissipation effect.

[0038] In addition, if Figure 4 As shown, slots 11 are respectively provided on the two ends of the round sleeve 601, the rear end of the housing 1 and the rear end cover 5 of this embodiment, and the slots 11 are engaged with each other. It should be noted that the two slots 11 at the rear end of the housing 1 and the round sleeve 601 near one end of the housing 1 are engaged with each other, that is, the slots 11 are arranged oppositely, so that the side walls of the two slots 11 can abut and engage with each other, and then a sealing ring is added to play a sealing role. The slots 11 at the rear end cover 5 and the round sleeve 601 near one end of the rear end cover 5 are the same as above, and also play a sealing role. Ensure that the coolant or cooling oil will not leak when circulating in the housing 1 and the round sleeve 601.

[0039] Based on the above overall introduction, an exemplary structure of the circulating liquid cooling heat dissipation motor of this embodiment is as follows: Figure 5 As shown, the circulation mechanism 6 includes a circular sleeve 601 fixedly arranged at the rear end of the housing 1, a bracket 602 fixedly arranged in the circular sleeve 601, and a gear set 603 rotatably arranged on the bracket 602, and an impeller 604 is fixedly arranged on the gear set 603.

[0040] It should be noted that the circular sleeve 601 is located at the rear end of the outer shell 1 and is connected to the outer shell 1. The cooling oil or coolant can circulate between the two and then flow through the radiator 7 to complete the heat dissipation work. The bracket 602 is provided with three legs, and the three legs are respectively fixedly mounted on the inner wall of the circular sleeve 601. The gear set 603 is driven by the rotor 3 and rotates on the bracket 602. The impeller 604 is fixedly connected to the gear on the gear set 603. When the gear set 603 rotates, it drives the impeller 604 to rotate. The impeller 604 can drive the coolant or cooling oil in the circular sleeve 601 to flow, and cooperate with the radiator 7 to form a circulation.

[0041] As a preferred example, Figure 3 and Figure 5 As shown, the central axis of the rotor 3 of this embodiment passes through the circular sleeve 601 and the rear end cover 5 and is keyed to the radiator 7, the end of the bracket 602 is fixedly connected to the inner wall of the circular sleeve 601, and the gear set 603 is driven by the rotor 3. The gear set 603 includes a small gear 6031 fixedly set on the central axis of the rotor 3 and a large gear 6032 rotatably set on the bracket 602, and the impeller 604 is fixedly connected to the large gear 6032. A through slot 605 is opened in the center of the bracket 602, and the central axis of the rotor 3 passes through the through slot 605.

[0042] Specifically, the central axis of the radiator 7 and the bracket 602 is concentric with the central axis of the outer casing 1. Only in this way can the rotor 3 drive the radiator 7 and the gear set 603 to work. There is at least one impeller 604. Of course, multiple impellers can be set according to actual conditions to achieve different circulation speeds. The end of the bracket 602 is the three legs of the bracket 602. The purpose of setting the three legs is to ensure that the bracket 602 can be stably supported in the circular sleeve 601. The gear set 603 is rotatably connected to the bracket 602, so it can be driven by the rotor 3.

[0043] In addition, the reason why the rotor 3 can drive the gear set 603 is that the pinion 6031 is sleeved on the central axis of the rotor 3 and is fixedly connected to the rotor 3. When the rotor 3 rotates, the pinion 6031 is driven to rotate, and the pinion 6031 and the large gear 6032 are meshed for transmission, and the large gear 6032 is connected to the rotating shaft of the bracket 602, so the pinion 6031 can drive the large gear 6032 to rotate, and the central axis of the impeller 604 is fixedly connected to the central axis of the large gear 6032, so when the large gear 6032 rotates, it can drive the impeller 604 to rotate. In order to improve the fluidity, a plurality of openings can be provided on the large gear 6032 to facilitate the circulation of coolant or cooling oil. The diameter of the through groove 605 provided on the central axis of the bracket 602 is larger than the diameter of the central axis of the rotor 3, ensuring that the rotor 3 will not rub against the through groove 605 when rotating.

[0044] As a preferred example, Figure 2 and Figure 6As shown, the radiator 7 of this embodiment includes a heat sink 701 fixedly arranged on the rear end cover 5, a heat dissipation pipe 702 coiled on the heat sink 701, and a fan blade 703 rotatably arranged on the central axis of the rotor 3. Through holes 9 are respectively opened on the front end cover 4 and the rear end cover 5, and the two through holes 9 are connected to the inlet and outlet of the heat dissipation pipe 702 through two connecting pipes 10 respectively.

[0045] It should be noted that the heat sink 701 is fixedly mounted on the rear end cover 5. Since the central axis of the rotor 3 passes through the rear end cover 5, it also passes through the heat sink 701. In other words, a circular hole is opened on the central axis of the heat sink 701. The diameter of the circular hole is larger than the diameter of the central axis of the rotor 3 to avoid friction. After the central axis of the rotor 3 passes through the heat sink 701, it is key-connected with the fan blade 703 to ensure that the fan blade 703 can be driven to rotate, thereby cooling the heat sink 701. The heat pipe 702 is coiled inside the heat sink 701. When the coolant or cooling oil flows through the heat pipe 702, The heat sink 701 can dissipate the cooling oil or the coolant, and the fan blades 703 dissipate the heat on the heat sink 701, thereby improving the heat dissipation efficiency. The connecting pipe 10 is connected to the heat dissipation pipe 702, and is respectively connected to the front cover 4 and the rear cover 5, that is, the impeller 604 drives the coolant or the cooling oil to flow from the outer shell 1 into the circular sleeve 601, and then enters the heat dissipation pipe 702 from the through hole 9 of the rear cover 5 and one of the connecting pipes 10 for heat dissipation, and then flows into the outer shell 1 from the through hole 9 of the front cover 4 and the other connecting pipe 10, forming a cycle to achieve the purpose of heat dissipation.

[0046] The circulating liquid-cooled heat dissipation motor in this embodiment ensures that the liquid can flow in the circulating mechanism 6 and the shell 1 through the coordinated arrangement of the circulating mechanism 6 and the shell 1, thereby achieving the purpose of circulation. The arrangement of the radiator 7 can improve the heat dissipation efficiency of the liquid, thereby achieving the heat dissipation purpose. The arrangement of the wind cover 8 can prevent dust from falling on the radiator 7, thereby affecting the heat dissipation effect and improving the service life of the equipment. The coordinated arrangement of the gear set 603 and the impeller 604 ensures that the liquid inside the circulating mechanism 6 can flow, thereby realizing circulation and achieving the purpose of cooling.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
