[0040] Referring to Figures 1 to 15 shown in the figure, according to the embodiment of the present application, the cooling housing includes a motor cylinder 1 and a heat dissipation module 2. A cooling flow channel 3 is provided on the heat dissipation module 2, and a module installation groove 4 is provided on the motor cylinder 1. The installation quantity and position of the heat dissipation module 2 on the motor cylinder 1 are adjustable.

[0041] The heat dissipation module 2 of the cooling housing is installed on the motor cylinder body 1. The entire heat dissipation system is composed of one or more heat dissipation modules 2, and the number and position of the heat dissipation modules 2 can be freely selected according to the heat generation power of the high-speed motor, the use environment, and the position of the power devices, and can be appropriately adjusted according to the actual operating conditions of the motor. Each heat dissipation module 2 can effectively dissipate heat by using the heat dissipation flow channel. Therefore, the number of heat dissipation modules and the placement position of the modules can be reasonably selected in combination with the use environment and working conditions of the motor to meet the diverse and flexible requirements of the high-speed motor for the heat dissipation flow channel.

[0042] In one embodiment, at least two installation positions are axially provided on the motor cylinder body 1, and the heat dissipation module 2 can be selectively installed on the installation positions. In this embodiment, heat dissipation modules 2 can be provided on each installation position of the motor cylinder body 1, or only some of them can be provided. The specific setting situation can be selected according to the actual heat dissipation situation of the motor. The heat dissipation modules 2 can be directly connected or connected through a connection structure to achieve series or parallel connection between the heat dissipation modules 2.

[0043] The connection structure can have various lengths. When the heat dissipation modules 2 are arranged at intervals, according to the distance between adjacent heat dissipation modules 2, a connection structure with a suitable length can be selected to connect the two heat dissipation modules 2 arranged at intervals. Therefore, it can be ensured that no matter how the heat dissipation modules 2 are arranged, a mutually connected cooling structure can be formed, which is convenient for realizing the circulating flow of the coolant.

[0044] In one embodiment, the motor cylinder body 1 includes an installation frame, and the installation frame includes end structures 5, longitudinal beams 6, and cross beams 7. There are two end structures 5, and the two end structures 5 are located at both ends of the motor cylinder body 1. The longitudinal beams 6 extend along the axis of the motor cylinder body 1 and are connected between the two end structures 5. The cross beams 7 extend along the circumference of the motor cylinder body 1, and the cross beams 7 are cross-connected with the longitudinal beams 6. The cross beams 7 are axially located between the two end structures 5.

[0045] In this embodiment, by adopting a frame structure for the motor cylinder body 1, while forming the basic frame of the motor cylinder body 1, the space formed by the frame structure can be used to form installation positions for installing the heat dissipation modules 2. The frame structure has a simple overall structure, a large available space, and is convenient for layout. Therefore, it is more convenient to arrange the installation of the heat dissipation modules 2, and it is also more convenient to select a suitable position for adjusting the position of the heat dissipation modules 2, so that the installation position of the heat dissipation modules 2 can achieve the maximum cooling effect.

[0046] In this embodiment, the end structures 5 at both ends of the installation frame are the end structures at both ends of the motor cylinder body 1. On the one hand, they are used for the installation and fixation of bearings, etc. On the other hand, cooling channels can be conveniently arranged to achieve docking with the heat dissipation module 2. The end structures 5 are connected by longitudinal beams 6, and the cross beams 7 are arranged crosswise with the longitudinal beams 6, so that multiple partition areas can be formed between the cross beams 7, the longitudinal beams 6 and the end structures 5, and each partition area can form multiple installation positions for installing the heat dissipation module 2. The structure in which the longitudinal beams 6 and the cross beams 7 are arranged crosswise can not only facilitate the division of installation positions, but also enhance the overall structural strength of the motor cylinder body 1, and can also facilitate the arrangement of the installation structure of the heat dissipation module 2.

[0047] In one embodiment, there are at least two longitudinal beams 6, and at least one installation position is formed between two adjacent longitudinal beams 6, the cross beam 7 and an end structure 5. The heat dissipation module 2 in this embodiment is arranged along the axial direction of the motor cylinder body 1. Therefore, the cross beams 7 spaced apart axially will interfere with the connection of the heat dissipation module 2. To avoid such interference, through holes or grooves penetrating along the axial direction can be arranged on the cross beam 7, so that the connection structure for connecting the heat dissipation module 2 can pass through the cross beam 7 without obstruction, and the connection of the heat dissipation module 2 on both sides of the cross beam 7 can be realized.

[0048] When the installation frame includes two longitudinal beams 6, one cross beam 7 and two end structures 5, the two longitudinal beams 6, one cross beam 7 and the two end structures 5 are connected together to form four partition areas, and each partition area can be provided with multiple installation positions for installing the heat dissipation module 2.

[0049] In one embodiment, a step structure 8 is arranged on at least one longitudinal beam 6, and at least two installation holes 9 are arranged along the axial direction on the step surface of the step structure 8, and each installation hole 9 corresponds to an installation position. One end of the heat dissipation module 2 can be lapped on the step structure 8, and connection holes can be arranged on the lapping structure of the heat dissipation module 2. After the connection holes are aligned with the installation holes 9, they are fixedly connected to the longitudinal beam 6 through bolts, etc., to realize the installation and fixation of the heat dissipation module 2.

[0050] In other embodiments, on the same step structure 8, multiple installation holes 9 can also correspond to one installation position.

[0051] In other embodiments, step structures 8 can also be arranged on both longitudinal beams. Both ends of the heat dissipation module 2 are lapped on the step structures 8 through lapping structures, and then the heat dissipation module 2 can be pressed and fixed on the step structures 8 through a pressing plate. Since no installation holes 9 need to be arranged in this structure, the installation position of the heat dissipation module 2 on the motor cylinder body 1 can be adjusted more flexibly and the position control can be more accurate. Both ends of the pressing plate can be fixedly connected to the end structure 5, so as to form the maximum length of pressing and fixing.

[0052] To avoid the pressing plate being too long and deforming in the middle, resulting in ineffective pressing, and to improve the pressing and fixing ability of the pressing plate, in one embodiment, one end of the pressing plate can be fixed to the end structure, and the other end can be fixed to the cross beam 7, thereby shortening the length of the pressing plate and improving the stiffness of the pressing plate.

[0053] In this embodiment, the installation position is arranged axially. In other embodiments, the installation position can also be arranged circumferentially. At this time, the arrangement direction of the heat dissipation module 2 also changes accordingly. In this case, a step can be provided on the cross beam 7 to achieve the installation and fixation of the heat dissipation module 2.

[0054] In one embodiment, the motor cylinder 1 includes an inner cylinder wall 10, and the heat dissipation module 2 is located on the outer peripheral side of the inner cylinder wall 10. In this embodiment, the heat dissipation module 2 is attached to the inner cylinder wall 10, which is convenient for transferring the heat on the inner cylinder wall 10 and can effectively improve the cooling efficiency. The inner cylinder wall 10 can be set as a complete thin-walled structure, which can form effective contact with other internal components, is more convenient for heat transfer, has higher heat transfer efficiency, and can also effectively protect the components inside the motor cylinder 1 through the inner cylinder wall 10.

[0055] In one embodiment, when a step structure 8 is provided on at least one longitudinal beam 6, a card slot 11 is formed between the longitudinal beam 6 adjacent to the longitudinal beam 6 and the inner cylinder wall 10. A connecting arm 12 is provided on the outer periphery of the first end of the heat dissipation module 2. The connecting arm 12 extends outward circumferentially from the edge of the heat dissipation module 2. An installation plug 13 is provided on the inner periphery of the second end of the heat dissipation module 2. The connecting arm 12 is installed on the step structure 8, and the installation plug 13 is inserted into the card slot 11.

[0056] In this embodiment, a connecting hole is provided on the connecting arm 12. When installing and fixing the heat dissipation module 2, the installation plug 13 at one end of the heat dissipation module 2 can be first inserted into the card slot 11 to fix one end of the heat dissipation module 2. Then, the connecting arm 12 at the other end of the heat dissipation module 2 is lapped on the step structure 8, so that the connecting hole on the connecting arm 12 is aligned with the installation hole 9 on the step structure 8, and then fixed by tightening with bolts. In this embodiment, the installation hole 9 is a threaded hole. One end of the heat dissipation module 2 is clamped and fixed, and the other end is bolt-fixed, which can make the installation structure of the heat dissipation module 2 simple, the fixation stable and reliable, not only convenient for installation and disassembly, but also ensure the effectiveness of the connection structure and avoid relative displacement.

[0057] In one embodiment, at least one end of the motor cylinder 1 is provided with a liquid inlet channel 14 and a liquid outlet channel 15. The heat dissipation module 2 is provided with a liquid inlet interface and a liquid outlet interface. The liquid inlet interface is communicated with the liquid inlet channel 14, and the liquid outlet interface is communicated with the liquid outlet channel 15.

[0058] The liquid inlet channel 14 includes a radial channel and a circumferential channel. The radial channel extends along the radial direction of the motor cylinder body 1, and the circumferential channel extends along the circumferential direction of the motor cylinder body 1 to both sides of the longitudinal beam 6. The radial channel is communicated with the circumferential channel. The first end of the circumferential channel is communicated with the heat dissipation module 2 on the first side of the longitudinal beam 6, and the second end of the circumferential channel is communicated with the heat dissipation module 2 on the second side of the longitudinal beam 6.

[0059] The liquid outlet channel 15 includes a radial channel and a circumferential channel. The radial channel extends along the radial direction of the motor cylinder body 1, and the circumferential channel extends along the circumferential direction of the motor cylinder body 1 to both sides of the longitudinal beam 6. The radial channel is communicated with the circumferential channel. The first end of the circumferential channel is communicated with the heat dissipation module 2 on the first side of the longitudinal beam 6, and the second end of the circumferential channel is communicated with the heat dissipation module 2 on the second side of the longitudinal beam 6.

[0060] In this embodiment, the radial channel is communicated radially outward from the axial channel, and the external coolant can be communicated with the radial channel to supply liquid to the liquid inlet channel 14 through the radial channel. After the coolant enters the liquid inlet channel 14, it can flow to both circumferential sides from the circumferential channel of the liquid inlet channel 14. An axial channel penetrating the end face of the end part structure 5 is provided at the end of the circumferential channel. The axial channel is communicated with the heat dissipation module 2. The coolant enters the heat dissipation module 2 from the axial channel, then flows out from the liquid outlet of the heat dissipation module 2, enters the axial channel of the liquid outlet channel 15, and then flows out of the cooler housing through the circumferential channel and the radial channel of the liquid outlet channel 15 to form a cooling cycle.

[0061] In one embodiment, the heat dissipation module 2 includes a main body. A cooling flow channel 3 is arranged inside the main body. A first interface 16 is arranged at the first end of the main body in the axial direction, and a second interface 17 is arranged at the second end. Both the first interface 16 and the second interface 17 are communicated with the cooling flow channel 3. Adjacent main bodies can be connected through a connecting pipe 18. One end of the connecting pipe 18 is connected to the first interface 16 of one main body, and the other end is connected to the second interface 17 of another main body. A sealing plug 21 is arranged at the first interface 16 or the second interface 17 of at least one heat dissipation module 2, and the setting position of the sealing plug 21 is determined by the connection relationship between the heat dissipation module 2 and the liquid inlet channel 14 and the liquid outlet channel 15.

[0062] In this embodiment, two first interfaces 16 are provided at the first end in the axial direction of each heat dissipation module 2, and the two first interfaces 16 are respectively located at both ends in the circumferential direction of the heat dissipation module 2. According to the different connection positions of the heat dissipation module 2 and the liquid inlet channel 14 on the end structure 5, one of the first interfaces 16 can be used as the liquid inlet for liquid supply, and the other first interface 16 can be used as the liquid outlet for liquid return. Similarly, the second interface 17 corresponding to the first interface 16 serving as the liquid inlet for liquid supply is used as the liquid outlet for liquid supply, and the second interface 17 corresponding to the first interface 16 serving as the liquid outlet for liquid return is used as the liquid inlet for liquid return, so as to facilitate the connection between the heat dissipation modules 2 and the communication of the flow channels.

[0063] When two adjacent heat dissipation modules 2 are connected, at this time, between the adjacent heat dissipation modules 2, the correspondingly arranged first interface 16 and the second interface 17 are connected through a connecting pipe 18. At the position where there is a cross beam 7, the connecting pipe 18 passes through the through hole or the avoiding groove on the cross beam 7 to connect with the heat dissipation module 2 on the other side of the cross beam 7. The two first interfaces 16 of the heat dissipation module 2 closest to the liquid inlet channel 14 are connected to the two axial channels of the liquid inlet channel 14 through the connecting pipe 18, and the two second interfaces 17 of the heat dissipation module 2 farthest from the liquid inlet channel 14 are sealed by a sealing plug 21, so as to seal the interfaces at the end, preventing liquid leakage while ensuring the effective return of the coolant.

[0064] In one embodiment, there are multiple connecting pipes 18, and at least two of the connecting pipes 18 have different lengths. The connecting pipes 18 can be selectively connected between two adjacent heat dissipation modules 2. Since the lengths of the connecting pipes 18 are different, the optional positions and arrangement methods of the heat dissipation modules 2 are more diversified, and the heat dissipation requirements of the motor can be better met.

[0065] In one embodiment, the connecting pipe 18 includes a threaded joint 19 and a clamping joint 20. The threaded joint 19 is threadedly connected to the first interface 16, and the clamping joint 20 is clamped to the second interface 17. In this embodiment, since the connecting pipe 18 has a threaded joint 19, the interface connected to the threaded joint 19 of the connecting pipe 18 is correspondingly provided with an internal thread, and the thread connection can be used to improve the connection strength and sealing performance. The other end of the connecting pipe 18 is clamped to the second interface 17, the connection structure is simpler, and the installation and disassembly are more convenient. To ensure the sealing effect of the clamping, the clamping joint 20 has a tapered head and a stop step located at the end of the tapered head. The clamping joint 20 can be made of an elastic material. The tapered head is used for guiding, and the deformation of the stop step enables the clamping joint 20 to smoothly enter the second interface 17 or the axial channels of the liquid inlet channel 14 and the liquid outlet channel 15, reducing the installation difficulty. Stop steps are provided in the second interface 17, the liquid inlet channel 14, and the liquid outlet channel 15. After being installed in place, the clamping joint 20 restores its deformation, and the stop step on the clamping joint 20 stops on the stop step of the corresponding interface, preventing the clamping joint 20 from coming out. At the same time, the elastic deformation of the clamping joint 20 can be used to form a seal to prevent the coolant from leaking.

[0066] In one embodiment, the connecting pipe 18 is a rubber pipe.

[0067] In one embodiment, the connecting pipe 18 can also adopt a hybrid structure, where the threaded joint 19 is made of a rigid material and the clamping joint 20 is made of an elastic material.

[0068] In one embodiment, the cross-section of the heat dissipation module 2 is fan-shaped or rectangular, specifically determined by the shape of the module installation groove 4.

[0069] According to the embodiment of the present application, the motor includes a cooling housing, and this cooling housing is the above-mentioned cooling housing.

Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above is only the preferred implementation manner of the present application.
