Description

Technical Field

[0001] The present invention relates to the technical field of motor cooling, and more specifically, to a water-cooled machine base and a generator. Background Art

[0002] At present, some motors pursue low noise and silent effects, delete high-noise source fans, and use liquid cooling. In addition, at high altitudes, the air is thin in the plateau, which is not conducive to heat dissipation, and using liquid as a cooling medium is also a good choice.

[0003] Compared with a motor cooled by natural air, due to different heat dissipation methods, the structural design of the motor is also different. A motor cooled by liquid requires a liquid circulation passage. In the motor, the main heat-generating component is the iron core, so the machine base for assembling the iron core should have liquid passing through.

[0004] The liquid passage of the liquid-cooled machine base is relatively complex, and it is necessary to ensure smooth liquid flow without leakage. Therefore, the processing and manufacturing are relatively difficult, and generally, the casting method is used for production. However, for a newly developed product under preliminary research, the mold-opening method is used for production, which has a long production cycle and relatively high costs, and the casting method is not suitable. Summary of the Invention

[0005] The purpose of the present invention is to provide a water-cooled machine base, which can achieve an effective cooling effect, shorten the production cycle, and save the R & D cost.

[0006] Another purpose of the present invention is to provide a generator, which can achieve an effective cooling effect, shorten the production cycle, and save the R & D cost.

[0007] The present invention provides a technical solution:

[0008] A water-cooled machine base, the water-cooled machine base includes a first mounting member, a second mounting member, and a machine base body. The first mounting member and the second mounting member are respectively welded to both ends of the machine base body, and the first mounting member and the second mounting member are used for connecting to a motor.

A plurality of second installation holes are formed in the second installation member, and the plurality of second installation holes penetrate through the second installation member.

[0013] Furthermore, the water flow channel includes a plurality of first channel segments, a plurality of second channel segments, and a plurality of third channel segments. The plurality of first channel segments all extend from one end of the main body of the machine base to the other end of the main body of the machine base.

[0015] Furthermore, the plurality of second channel segments and the plurality of third channel segments all extend along an arc path, and the arc path is centered on the axis of the main body of the machine base.

[0016] Furthermore, the water-cooled machine base further includes a liquid inlet pipe and a liquid outlet pipe. The liquid inlet pipe and the liquid outlet pipe are both connected to the main body of the machine base. The internal channel of the liquid inlet pipe communicates with one of the first channel segments, and the internal channel of the liquid outlet pipe communicates with another adjacent first channel segment.

[0017] A generator includes a water-cooled machine base. The water-cooled machine base includes a first installation member, a second installation member, and a main body of the machine base. The first installation member and the second installation member are respectively welded to both ends of the main body of the machine base, and the first installation member and the second installation member are used for connecting to the motor.

[0032] The following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings.

[0033] First Embodiment

[0034] Please refer to Figure 1 , in this embodiment, a water-cooled machine base 10 is provided, which is applied to an electric motor (not shown in the figure), and the water-cooled machine base 10 is used for the heat dissipation and cooling of the generator to ensure that the electric motor can work stably in a stable temperature environment. The water-cooled machine base 10 can achieve an effective cooling effect, and can shorten the production cycle and save the R & D cost.

[0035] The water-cooled machine base 10 includes a first mounting member 200, a second mounting member 300 and a machine base body 100. The first mounting member 200 and the second mounting member 300 are respectively welded to both ends of the machine base body 100, and are mounted on the motor through the first mounting member 200 and the second mounting member 300, that is, the first mounting member 200 and the second mounting member 300 are used to be mounted on the motor, so as to realize the installation of the water-cooled machine base 10 on the motor as a whole, so as to dissipate heat and cool the motor.

[0036] Compared with the prior art, the liquid-cooled machine base is usually manufactured by the mold opening method, that is, the liquid-cooled machine base is manufactured by the casting setting method, which has a long production cycle, high cost and great processing difficulty. In this embodiment, the first mounting member 200, the second mounting member 300 and the machine base body 100 are manufactured separately, and the first mounting member 200, the second mounting member 300 and the machine base body 100 are connected as a whole by welding, which simplifies the processing difficulty, shortens the production cycle, and saves the research and development cost.

[0037] It should be noted that the motor has a motor core (not shown), and most of the heat generated by the motor is generated by the operation of the motor core, wherein the water-cooled base 10 is used to dissipate heat and cool the motor core.

[0038] Please refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, an installation space 110 is provided inside the base body 100, and the installation space 110 is used to install the motor core, so that the heat of the motor core can be dissipated into the installation space 110, and the heat is dissipated through the peripheral wall of the base body 100. Furthermore, a water flow channel 120 is provided in the side wall surrounding the installation space 110, and the water flow channel 120 is used to pass a coolant that absorbs the heat inside the installation space 110. That is, in this embodiment, by passing a coolant into the water flow channel 120, the heat absorbed from the installation space 110 by the inner peripheral wall of the installation space 110 can be taken away by the coolant, and the motor core can be indirectly cooled and dissipated.

[0039] Among them, by passing the coolant into the water flow channel 120 to dissipate the heat of the motor core, the noise caused by the heat dissipation and cooling method of the prior art through air cooling can be avoided, and the design space can be saved, which is convenient for the miniaturization of the water-cooled machine base 10. In addition, the heat dissipation and cooling of the motor core by the coolant can improve the heat dissipation and cooling effect of the motor core, and further ensure that the motor can operate in an environment with a stable temperature environment.

[0040] The water flow channel 120 includes a plurality of first channel segments 121, a plurality of second channel segments 122, and a plurality of third channel segments 123. The plurality of first channel segments 121, the plurality of second channel segments 122, and the plurality of third channel segments 123 are communicated with each other and form the entire water flow channel 120. Among them, the plurality of first channel segments 121 all extend from one end of the base body 100 to the other end of the base body 100. The plurality of second channel segments 122 are disposed on one end face of the base body 100, and the plurality of third channel segments 123 are all disposed on the other end face of the base body 100, that is, the plurality of second channel segments 122 and the plurality of third channel segments 123 are respectively disposed on two opposite end faces of the base body 100.

[0041] It should be noted that in this embodiment, the fact that the plurality of first channel segments 121, the plurality of second channel segments 122, and the plurality of third channel segments 123 are communicated with each other means that both ends of a first channel segment 121 are respectively communicated with a second channel segment 122 and a third channel segment 123, both ends of a second channel segment 122 are respectively communicated with two adjacent first channel segments 121, and both ends of a third channel segment 123 are respectively communicated with two adjacent first channel segments 121. And, in this embodiment, the arrangement manner of the plurality of first channel segments 121, the plurality of second channel segments 122, and the plurality of third channel segments 123 in the water flow channel 120 is: first channel segment 121, second channel segment 122, first channel segment 121, third channel segment 123, first channel segment 121, second channel segment 122, first channel segment 121, third channel segment 123. The plurality of first channel segments 121, the plurality of second channel segments 122, and the plurality of third channel segments 123 are arranged in sequence according to the above order, and both ends of the water flow channel 120 are first channel segments 121.

[0042] Through the above setting method, the water flow channel 120 is meanderingly arranged inside the side wall surrounding the installation space 110 in a way that extends in an S shape, so as to facilitate the coolant to fully absorb the heat dissipated inside the installation space 110 and ensure the heat dissipation and cooling effect on the motor iron core.

[0043] Specifically, in this embodiment, the straight line where the extending direction of the plurality of first channel segments 121 is located is parallel to the axis of the base body 100, and the plurality of first channel segments 121 are equally spaced along the circumferential direction of the base body 100. Among them, the circumferential direction of the base body 100 refers to the circumferential direction centered on the axis of the base body 100.

[0044] A plurality of second channel segments 122 and a plurality of third channel segments 123 both extend along an arc path, and the arc path is centered on the axis of the base body 100. Among them, in this embodiment, the plurality of second channel segments 122 are arranged at intervals, and the center formed by the plurality of second channel segments 122 is located on the axis of the base body 100. Similarly, the plurality of third channel segments 123 are arranged at intervals, and the center formed by the plurality of third channel segments 123 is located on the axis of the base body 100.

[0045] Further, please refer to Figures 1 to 4 , the water-cooled base 10 further includes a liquid inlet pipe 130 and a liquid outlet pipe 140. The liquid inlet pipe 130 and the liquid outlet pipe 140 are both connected to the base body 100, and the internal channel of the liquid inlet pipe 130 communicates with one of the first channel segments 121, and the internal channel of the liquid outlet pipe 140 communicates with another adjacent first channel segment 121. That is, the coolant can be injected into the water flow channel 120 through the liquid inlet pipe 130, and the coolant can be discharged from the water flow channel 120 through the liquid outlet pipe 140 to ensure the circulation of the coolant in the water flow channel 120 and improve the heat dissipation and cooling effect on the motor iron core.

[0046] In addition, in this embodiment, the first mounting member 200, the second mounting member 300, and the base body 100 are all made of aluminum alloy or aluminum material. The lightweight factor of the aluminum alloy or aluminum material can ensure the lightweight of the water-cooled base 10, and it is convenient to operate the first mounting member 200, the second mounting member 300, and the base body 100, which is convenient to simplify the processing difficulty of the water-cooled base 10, shorten the production cycle, and save costs.

[0047] It should be understood that in other embodiments, the manufacturing materials of the first mounting member 200, the second mounting member 300, and the base body 100 can also be selected from other materials, such as copper materials, iron materials, etc.

[0048] In this embodiment, the first mounting member 200 is annular, and the inner peripheral wall of the first mounting member 200 is flush with the inner peripheral wall of the base body 100, so as to facilitate the installation of the motor iron core after the connection between the first mounting member 200 and the base body 100, and avoid impact damage to the motor iron core.

[0049] It should be noted that the statement that the inner peripheral wall of the above-mentioned mounting member is flush with the inner peripheral wall of the base body 100 means that the inner diameter of the opening at one end of the first mounting member 200 installed on the base body 100 is the same as the inner diameter of the corresponding opening of the base body 100. When the first mounting member 200 is welded to the base body 100, the curved surface of the inner peripheral wall of the first mounting member 200 can be connected to the curved surface of the inner peripheral wall of the base body 100, avoiding the formation of a stepped structure and the potential threat of impacting and damaging the battery cell. At the same time, it is also convenient for welding the first mounting member 200 and the base body 100, reducing the welding difficulty.

[0050] Furthermore, a plurality of first mounting holes 210 are formed in the first mounting member 200, and the plurality of first mounting holes 210 penetrate through the first mounting member 200. By passing fixing members such as screws through the first mounting holes 210, the first mounting member 200 can be installed on the motor, thereby realizing the installation connection between the first mounting member 200 and the motor.

[0051] Furthermore, a mounting groove 150 is also formed in the base body 100. The mounting groove 150 is formed on the outer side of the base body 100 and communicates with the first mounting holes 210. The diameter of the mounting groove 150 is larger than the diameter of the first mounting holes 210.

[0052] It should be noted that in this embodiment, there are a plurality of mounting grooves 150, and the plurality of mounting grooves 150 respectively correspond to the plurality of first mounting holes 210, that is, the plurality of mounting grooves 150 respectively communicate with the plurality of first mounting holes 210. The fact that the diameter of the mounting groove 150 is larger than the diameter of the first mounting holes 210 means that the inner peripheral wall of the mounting groove 150 forms a circular contour outside the contour formed by the hole wall of the first mounting holes 210. Through the above setting method, it is convenient to pass fixing members such as screws through the first mounting member 200 from one side of the mounting groove 150 to connect to the motor, facilitating the setting of the fixing members.

[0053] In addition, in this embodiment, the second mounting member 300 is also annular, and the inner peripheral wall of the second mounting member 300 is flush with the inner peripheral wall of the base body 100. It should be noted that the statement that the inner peripheral wall of the second mounting member 300 is flush with the inner peripheral wall of the base body 100 means that the inner diameter of the opening at one end of the second mounting member 300 installed on the base body 100 is the same as the inner diameter of the corresponding opening of the base body 100. When the second mounting member 300 is welded to the base body 100, the curved surface of the inner peripheral wall of the second mounting member 300 can be connected to the curved surface of the inner peripheral wall of the base body 100, avoiding the formation of a stepped structure and the potential threat of impacting and damaging the battery cell. At the same time, it is also convenient for welding the second mounting member 300 and the base body 100, reducing the welding difficulty.

[0054] Further, a plurality of second mounting holes 310 are formed in the second mounting member 300, and the plurality of second mounting holes 310 penetrate through the second mounting member 300. In this embodiment, the plurality of second mounting holes 310 penetrate through the second mounting member 300 and extend into the interior of the base body 100. Among them, fixing members such as screws can be inserted into the second mounting holes 310 to mount the second mounting member 300 to the motor. It should be noted that by passing through the second mounting holes 310 into the interior of the base body 100, fixing members such as screws can extend into the interior of the base body 100 through the second mounting holes 310, which can ensure the stability of the base body 100 during operation, and further ensure the overall operation stability of the water-cooled base 10.

[0055] It should be noted that the first mounting member 200 and the second mounting member 300 are flange plates. That is, in this embodiment, the base body 100 is mounted on the motor by two flange plates provided at both ends of the base body 100.

[0056] The water-cooled base 10 provided in this embodiment can be mounted on the motor through the first mounting member 200 and the second mounting member 300, so that the motor core can be mounted inside the mounting space 110, and the heat inside the mounting space 110 can be absorbed by the coolant inside the water flow channel 120, and then the heat dissipation work of the motor core can be carried out. By using the coolant to dissipate heat from the motor cell, the noise caused by fan heat dissipation is avoided, and the heat dissipation effect on the motor core can be improved. In addition, the first mounting member 200 and the second mounting member 300 are connected to both ends of the base body 100 by welding, which improves the overall production efficiency, shortens the production cycle, and also saves the R & D cost.
