[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0028] The following is a reference appendix. Figure 1-4 Description of a motor housing 100 according to an embodiment of the present utility model.
[0029] Reference Figure 1 , Figure 2 and Figure 4 According to an embodiment of the present invention, the motor housing 100 includes: a main body 10 and two end caps 20. Specifically, the main body 10 is cylindrical, and a plurality of first heat exchange channels 14 are provided on the main body 10 at intervals along the circumference of the main body 10. That is, the main body 10 may have two, three, four or more first heat exchange channels 14, which penetrate the main body 10 along the axial direction. The two end caps 20 respectively cover the main body 10 in the axial direction (e.g., ...). Figure 1On both sides of the front and back direction shown, at least one end cap 20 has a second heat exchange channel 22 formed. That is, the second heat exchange channel 22 can be formed on one end cap 20, or the first heat exchange channel 14 can be formed on both end caps 20. The first heat exchange channel 14 is connected to the second heat exchange channel 22.
[0030] For example, such as Figure 1 , Figure 2 and Figure 4 As shown, the main body 10 is a hollow cylindrical structure extending in the front and back direction. The main body 10 is provided with nine first heat exchange channels 14, which penetrate the main body 10 in the front and back direction. The end cap 20 has a second heat exchange channel 22, and the first heat exchange channels 14 and the second heat exchange channels 22 are connected.
[0031] The motor housing 100 of this utility model has a second heat exchange channel 22 provided on the end cover 20. The second heat exchange channel 22 can exchange heat on the motor in the axial direction of the motor housing 100, such as the stator end of the motor, thereby improving the heat exchange effect of the motor and effectively preventing the motor from being damaged by high temperature. At the same time, the second heat exchange channel 22 is connected to the first heat exchange channel 14, and the second heat exchange channel 22 can connect multiple first heat exchange channels 14. The cooperation of the first heat exchange channels 14 and the second heat exchange channel 22 can effectively increase the heat exchange area, thereby heat exchange on the entire outer wall of the motor, thus further improving the heat exchange effect.
[0032] In addition, the second heat exchange channel 22 is positioned reasonably. The second heat exchange channel 22 is set using the existing end cover 20, eliminating the need for additional structures to arrange the second heat exchange channel 22. This can improve the functional integration of the end cover 20, reduce the use of parts, and lower production costs.
[0033] According to an embodiment of the present invention, a second heat exchange channel 22 is provided on the end cover 20 of the motor housing 100. The second heat exchange channel 22 can exchange heat with the motor in the axial direction of the motor housing 100, effectively improving the heat exchange effect and effectively preventing the motor from being damaged by high temperature. At the same time, the first heat exchange channel 14 and the second heat exchange channel 22 work together to effectively increase the heat exchange area, thereby further improving the heat exchange effect on the motor.
[0034] According to some embodiments of this utility model, refer to Figure 2 and Figure 4 There are multiple second heat exchange channels 22, that is, there can be two, three or four or more second heat exchange channels 22. Multiple second heat exchange channels 22 are arranged at intervals along the circumference of the end cover 20. Each second heat exchange channel 22 is connected to the first heat exchange channel 14 adjacent to the main body 10 in the circumference direction.
[0035] By setting up multiple second heat exchange channels 22, it can be ensured that multiple first heat exchange channels 14 can be connected through the second heat exchange channels 22, thereby allowing the refrigerant to circulate within the entire motor housing 100 and effectively ensuring the heat exchange effect. At the same time, the arrangement of the second heat exchange channels 22 is reasonable, making full use of the space of the end cover 20, thus improving the rationality of the arrangement of the second heat exchange channels 22.
[0036] For example, such as Figure 2 and Figure 4 As shown, four second heat exchange channels 22 are provided on the end cover 20, and the four heat exchange channels are arranged at intervals along the circumference of the end cover 20.
[0037] According to some embodiments of this utility model, refer to Figure 2 and Figure 3 The main body 10 includes a first plate 11, a second plate 12, and a plurality of partition ribs 13. That is, the main body 10 may include two, three, four or more partition ribs 13. The first plate 11 is an annular cylindrical shape; the second plate 12 is formed into an annular shape and is located radially inside the first plate 11; the plurality of partition ribs 13 extend along the axial direction of the main body 10 and are arranged at intervals in the circumference of the main body 10. The partition ribs 13 connect the first plate 11 and the second plate 12. The plurality of partition ribs 13, the first plate 11 and the second plate 12 cooperate to define a plurality of first heat exchange channels 14.
[0038] In this way, by setting the first plate 11 and the second plate 12, the main body 10 is formed into a double-layer structure, which can ensure the structural strength of the main body 10 and effectively prevent damage to the main body 10. At the same time, the partition rib 13 can not only act as a partition, but also cooperate with the first plate 11 and the second plate 12 to define the second heat exchange channel 22, eliminating the need for further processing of the second heat exchange channel 22, thereby reducing processing steps and improving processing efficiency. In addition, the partition rib 13 can also connect the first plate 11 and the second plate 12, thereby further strengthening the structural strength of the main body 10 and effectively preventing damage to the main body 10.
[0039] For example, such as Figure 2 and Figure 3 As shown, the first plate 11 is formed into a ring shape with open front and rear ends, and the second plate 12 is also formed into a ring shape with open front and rear ends. The second plate 12 is located on the radial inner side of the first plate 11, and the partition rib 13 is located between the first plate 11 and the second plate 12. The partition rib 13 connects the first plate 11 and the second plate 12.
[0040] According to some optional embodiments of the present invention, refer to Figure 2 and Figure 3The main body 10 has two end faces in the axial direction, namely a first end face 101 and a second end face 102. The plurality of partition ribs 13 include: a first rib 131 and a second rib 132. One end of the first rib 131 (e.g., Figure 2 The front end of the first rib 131 shown is flush with the first end face 101 and the other end (as shown) Figure 3 The rear end of the first rib 131 shown is located between the first end face 101 and the second end face 102, and one end of the second rib 132 (as shown) Figure 3 The rear end of the second rib 132 shown is flush with the second end face 102 and the other end (as shown) Figure 2 The front end of the second rib 132 shown is located between the first end face 101 and the second end face 102. The first rib 131 and the second rib 132 are arranged alternately along the circumference of the main body 10.
[0041] In this way, by cooperating with the first rib 131 and the second rib 132, the multiple first heat exchange channels 14 on the main body 10 can be connected in a meandering manner along the axial direction of the main body 10, thereby ensuring that the refrigerant can exchange heat with the entire main body 10, and thus effectively ensuring the heat exchange effect.
[0042] For example, such as Figure 2 and Figure 3 As shown, the front end face of the main body 10 is the first end face 101, the rear end face of the main body 10 is the second end face 102, the front end of the first rib 131 is flush with the first end face 101, the rear end of the first rib 131 is located between the first end face 101 and the second end face 102, the rear end of the second rib 132 is flush with the second end face 102, and the front end face of the second rib 132 is located between the first end face 101 and the second end face 102, thereby realizing that multiple first heat exchange channels are connected in an S-shape in the axial direction of the main body 10.
[0043] According to some embodiments of this utility model, refer to Figure 2 and Figure 3 The main body 10 has an inlet 15 and an outlet 16 on its side wall, and multiple first heat exchange channels 14 are connected in series between the inlet 15 and the outlet 16. Thus, the refrigerant can flow from the inlet 15 through the first heat exchange channel 14 to the outlet 16, thereby ensuring that the entire heat exchange channel is filled with refrigerant and thus effectively guaranteeing the heat exchange effect.
[0044] According to some embodiments of this utility model, refer to Figure 2 and Figure 3Each of the two end caps 20 has a second heat exchange channel 22 formed therein, which is recessed into the surface of the end cap 20 facing the main body 10. Thus, multiple first heat exchange channels 14 are connected through the second heat exchange channels 22 on the two end caps 20, ensuring that the first heat exchange channels 14 and the second heat exchange channels 22 form a complete series loop, thereby effectively guaranteeing the heat exchange effect. Furthermore, the second heat exchange channels 22 have a simple design and are easy to manufacture, thus effectively improving manufacturing efficiency.
[0045] For example, such as Figure 2 and Figure 4 As shown, a second heat exchange channel 22 is provided on the rear surface of the end cap 20 on the front side of the main body 10. The second heat exchange channel 22 on the end cap 20 is formed by recessing forward from the rear surface of the end cap 20. A second heat exchange channel 22 is provided on the front surface of the end cap 20 on the rear side of the main body 10. The second heat exchange channel 22 on the end cap 20 is formed by recessing backward from the front surface of the end cap 20.
[0046] According to some embodiments of this utility model, refer to Figure 2 and Figure 4 The end cap 20 is provided with a water-blocking rib 21, which is located on the side surface of the end cap 20 facing the main body 10. The water-blocking rib 21 is formed in a ring shape along the circumference of the end cap 20 and is located radially inside the second heat exchange channel 22. One end of the water-blocking rib 21 abuts against the end face of the main body 10. Thus, the water-blocking rib 21 can prevent refrigerant from flowing into the interior of the main body 10 from the gap between the end cap 20 and the main body 10, thereby effectively protecting the internal structure of the motor and ensuring the service life of the motor.
[0047] For example, such as Figure 2 and Figure 4 As shown, taking the end cap 20 on the front side of the main body 10 as an example, the rear side of the end cap 20 is provided with a water-blocking rib 21. The water-blocking rib 21 is formed in a ring along the circumference of the end cap 20. The rear end of the water-blocking rib 21 abuts against the first end face 101 of the main body 10. The end cap 20 on the rear side of the main body 10 and the end cap 20 on the front side of the main body 10 are arranged symmetrically in the front-rear direction.
[0048] According to some embodiments of this utility model, refer to Figure 2 and Figure 4 The end cover 20 is provided with a first fixing hole 23, which is arranged circumferentially with the second heat exchange channel 22. The main body 10 is provided with a second fixing hole 17 corresponding to the first fixing hole 23. The end cover 20 and the main body 10 are fixedly connected by fasteners passing through the first fixing hole 23 and the second fixing hole 17. Thus, the end cover 20 and the main body 10 are fixed by fasteners. This fixing method is simple in structure and convenient to operate, thereby effectively improving the assembly efficiency of the motor housing 100.
[0049] For example, such as Figure 2 and Figure 4 As shown, the end caps 20 on both the front and rear sides of the main body 10 are provided with first fixing holes 23. The first fixing holes 23 and the second heat exchange channel 22 are arranged at intervals along the circumference of the end caps 20. The end faces on both the front and rear sides of the main body 10 are formed with second fixing holes 17. Fasteners pass through the first fixing holes 23 and the second fixing holes 17 in sequence to fix the end caps 20 to the main body 10. Preferably, the fasteners are bolts. Bolts have a simple structure, low cost, and are easy to use in batches.
[0050] According to some embodiments of this utility model, refer to Figure 2 and Figure 4 The end cover 20 is provided with a bearing mounting port 24. This allows the bearing to be easily inserted into the bearing mounting port 24, thus facilitating the assembly of the motor.
[0051] According to some embodiments of this utility model, refer to Figure 2 and Figure 3 The main body 10 is extruded. Therefore, the extrusion molding process is simple and convenient to process, thereby improving processing efficiency. Compared to the existing technology that uses casting and requires welding to assemble the motor housing 100 after processing, the main body 10 of this application is connected to the end cap 20 by fasteners, thus saving welding steps, reducing assembly difficulty, and effectively improving assembly efficiency. Furthermore, the extrusion molding process is suitable for platform-based development, allowing the main body 10 to be processed according to actual needs, thereby effectively reducing development costs and development cycle.
[0052] According to the second aspect embodiment of the present invention, the motor is referred to... Figure 1 , Figure 2 and Figure 3 This includes the motor housing 100 of the first aspect of this embodiment.
[0053] According to the embodiment of the present invention, the motor housing 100 of the first aspect embodiment is provided, and a second heat exchange channel 22 is provided on the end cover 20. The second heat exchange channel 22 can exchange heat with the motor in the axial direction of the motor housing 100, effectively improving the heat exchange effect and effectively preventing the motor from being damaged by high temperature. At the same time, the first heat exchange channel 14 and the second heat exchange channel 22 cooperate to effectively increase the heat exchange area, thereby further improving the heat exchange effect on the motor.
