All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0037] The first embodiment of this utility model:
[0038] like Figure 1 This utility model discloses a slotted partition combined cooling structure suitable for high-speed motors, comprising a lower housing assembly 1, an upper housing assembly 2, and a motor 3 installed within the lower housing assembly 1. The lower housing assembly 1 and the upper housing assembly 2 are connected by several screws to form a cooling chamber. Multiple slotted flow channels are milled on the contact surface between the upper and lower housings. Several partitions are inserted into the slots to guide the cooling medium (which may be coolant) to flow in an "S" shaped path between the slots. The cooling medium inlet 13 and cooling medium outlet 14 are respectively located at the beginning and end positions of the flow channel for the cooling medium to enter and exit. This embodiment provides a water-cooled structure that forms an "S" shaped channel by milling straight slots on a flat housing and inserting cylindrical bars, which has the advantages of simple structure, high cooling efficiency, easy processing, and easy maintenance.
[0039] like Figure 2 and Figure 3 The lower housing assembly 1 mainly includes a lower housing 11. A mounting cavity 12 is provided inside the right side of the lower housing 11, and the motor 3 is installed in the mounting cavity 12. On the left side of the lower housing 11, from the outside to the inside, there are a lower housing connecting flange 15, a lower housing protruding end face 16, and a lower housing groove 17. The lower housing groove 17 is connected to the mounting cavity 12 on the right side.
[0040] like Figures 4-6 The upper housing assembly 2 mainly includes an upper housing 21. On the right side of the upper housing 21, from the outside to the inside, there are an upper housing connecting flange 22, an upper housing groove 23, and an upper housing protruding end face 25. On the left side of the upper housing 21, there is an upper housing mounting end face 24. On the upper housing 21 inside the upper housing mounting end face 24, there are several upper housing mounting blocks 28 arranged along the circumferential direction. The upper housing 21 is installed on the processing part through the upper housing mounting blocks 28.
[0041] The connection relationship between the lower housing assembly 1 and the upper housing assembly 2 is as follows:
[0042] During installation, the lower housing connecting flange 15 and the upper housing connecting flange 22 are connected together by several screws; the protruding end face 16 of the lower housing is embedded in the groove 23 of the upper housing, and then a first sealing ring is installed at the connection between the two; the protruding end face 25 of the upper housing is embedded in the groove 17 of the lower housing, and then a second sealing ring is installed at the connection between the two.
[0043] The lower housing groove-shaped flow channel 18 is formed on the lower housing protrusion end face 16 of the lower housing 11:
[0044] The lower housing protruding end face 16 includes, in a clockwise direction, a first flow channel 181, a second flow channel 182, a third flow channel 183, and a fourth flow channel 184. The first and second flow channels 181 and 182 have smaller spaces than the third and fourth flow channels 183 and 184. All the aforementioned flow channels are formed on the surface of the metal housing by CNC milling, and the bottom of the channels has a semi-circular or rectangular structure.
[0045] A cooling medium inlet 13 is installed on the lower housing 11 on one side of the first flow channel 181 of the lower housing, and a cooling medium outlet 14 is installed on the lower housing 11 on one side of the second flow channel 182 of the lower housing. Lower housing partitions 19 are installed near the middle of the lower housing third flow channel 183 and the lower housing fourth flow channel 184, which respectively divide the lower housing third flow channel 183 and the lower housing fourth flow channel 184 into two interconnected areas.
[0046] Upper shell groove-shaped flow channel 26 is formed on the upper shell groove 23 of the upper shell 21:
[0047] The upper shell groove 23 includes, in a clockwise direction, a first flow channel 261, a second flow channel 262, and a third flow channel 263, wherein the spaces of the first flow channel 261, the second flow channel 262, and the third flow channel 263 are substantially the same. Upper shell partitions 27 are installed near the center of each of the upper shell flow channels 261, 262, and 263, dividing them into two interconnected areas. All of the aforementioned flow channels are formed on the surface of the metal shell by CNC milling, and the bottom of the groove has a semi-circular or rectangular structure.
[0048] During operation, the cooling medium (coolant) enters the first flow channel 181 of the lower housing from the cooling medium inlet 13, then flows into the lower half of the first flow channel 261 of the upper housing, and is then transported through the upper housing partition 27 through the upper half of the first flow channel 261 to the upper half of the fourth flow channel 184 of the lower housing. It is then transported through the lower housing partition 19 through the lower half of the fourth flow channel 184 to the upper half of the second flow channel 262 of the upper housing, and then through the upper housing partition 27 through the lower half of the second flow channel 262 to the upper half of the third flow channel 183 of the lower housing. It is then transported through the lower housing partition 19 through the lower half of the third flow channel 183 of the lower housing to the upper half of the third flow channel 263 of the upper housing, and then through the upper housing partition 27 through the lower half of the third flow channel 263 of the upper housing to the second flow channel 182 of the lower housing. Finally, it is discharged through the cooling medium outlet 14.
[0049] Furthermore, standard connectors for connecting to an external cooling system are installed at the cooling medium inlet 13 and the cooling medium outlet 14, respectively. The overall structure of this embodiment can then be nested between the high-speed motor stator and the housing as a cooling jacket.
[0050] Both the lower housing partition 19 and the upper housing partition 27 are cylindrical rod-shaped structures that can be detachably inserted into the flow channels along the left-right direction and contact the upper and lower housings to form a sealed partition. Specifically, arc-shaped partition slots for accommodating the lower housing partition 19 and the upper housing partition 27 are respectively opened in the lower housing groove-shaped flow channel 18 and the upper housing groove-shaped flow channel 26, and the arc-shaped partition slots are distributed along the left-right direction, guiding the coolant from one flow channel to the next flow channel to achieve an "S"-shaped flow.
