[0002] The aluminum extrusion housing for passenger car motors is a motor housing made of aluminum alloy through an extrusion process. It has advantages such as light weight, high strength, good heat dissipation, and high thermal conductivity. This housing is mainly used to protect the internal components of the motor from damage caused by external dust, moisture, and mechanical impact. At the same time, it also has good electromagnetic shielding function, which can prevent internal electromagnetic radiation from interfering with external electronic equipment. Aluminum extrusion housing for passenger car motors with cooling channels is a type of motor housing manufactured using an aluminum extrusion process. It is designed with dedicated cooling channels inside to remove heat through coolant circulation during motor operation, thereby effectively controlling motor temperature and improving motor heat dissipation efficiency and operational stability. This design typically employs different channel structures, such as axial, circumferential, or spiral, depending on the specific needs of the motor, to optimize the cooling effect. When cooling the aluminum extrusion housing of a passenger car motor, both the housing and the housing cover need to be cooled. If the housing cover is not cooled, the end windings may overheat, which will affect the motor performance. Since the motor windings are located inside the housing cover, the cooling of the housing cover is very important. However, the housing and housing cover are usually separate structures. If the housing and housing cover are cooled separately, it will increase the cost of the cooling system. Therefore, to address the above problem, an aluminum extrusion housing for a passenger car motor with a cooling flow channel is proposed. Utility Model Content

[0016] Please see Figures 1-6 This utility model provides a technical solution: A passenger vehicle motor aluminum extrusion housing with cooling channels includes a housing assembly 1, a cover assembly 2 mounted on the upper end of the housing assembly 1, the housing assembly 1 including a housing body 11, the housing body 11 having an inlet channel 12, a bend 13 and a return channel 14 on its inner side, the cover assembly 2 including a cover body 21, the cover body 21 having an annular expansion groove 22 and a circular groove 28 on its inner side, the cover body 21 and a first insert shell 24 are integrally fixed, the cover body 21 and a second insert shell 27 are integrally fixed, a rubber sealing ring 25 is fixedly connected to the outer side of the first insert shell 24, an inlet connector 23 is fixedly connected to the rear end of the cover body 21, an outlet connector 26 is fixedly connected to the right side of the cover body 21, the inlet connector 23 communicates with the annular expansion groove 22, and the outlet connector 26 communicates with the circular groove 28.

[0017] As a further implementation of this solution, a fixing screw hole 15 is provided at the upper end of the housing body 11, and a fixing screw hole 15 is provided on the inner side of the cover body 21. The fixing screw hole 15 provided in the cover body 21 is intersected with the annular expansion groove 22 and the circular groove 28. The bottom end of the cover body 21 is attached to the top end of the housing body 11. The housing body 11 and the cover body 21 are fixed by bolts. Through the above settings, the effect of fixing the housing body 11 and the liquid inlet channel 12 is achieved. When intersecting, the fixing screw hole 15 is set to prevent communication between the annular expansion groove 22 or the circular groove 28. As a further implementation of this solution, the liquid inlet channel 12 and the return channel 14 both penetrate the upper end of the housing body 11. The liquid inlet channel 12, the bend 13 and the return channel 14 are connected. The multiple bends 13 and the return channels 14 are arranged in a circular array around the housing body 11 on the inner side of the housing body 11. Through the above arrangement, the coolant can be evenly distributed inside the entire housing body 11, which optimizes the cooling effect, improves the heat dissipation efficiency, simplifies the structure of the cooling system and reduces the cost. As a further implementation of this solution, the first insert shell 24 is inserted into the inside of the liquid inlet channel 12, and the second insert shell 27 is inserted into the inside of the return channel 14. Through the above arrangement, the insertion design enables the cooling channels between the housing body 11 and the liquid inlet channel 12 to be quickly connected, improving assembly efficiency, while ensuring the smooth flow of coolant and avoiding the risk of coolant leakage. As a further implementation of this solution, the first insert shell 24 is sealed to the liquid inlet channel 12 by a rubber sealing ring 25. The annular expansion groove 22 is annular in structure and is connected to the inner side of the first insert shell 24. The number of first insert shells 24 is the same as the number of liquid inlet channels 12. With the above settings, the annular expansion groove 22 of the annular structure can evenly distribute the coolant, achieve the purpose of cooling the engine cover body 21, ensure that the coolant flows evenly in each first insert shell 24, and further optimize the cooling effect. As a further implementation of this solution, a rubber sealing ring 25 is fixed to the outside of the second insert shell 27. The second insert shell 27 is sealed to the inside of the return channel 14 through the rubber sealing ring 25. The annular groove 28 communicates with the inside of the second insert shell 27. The number of second insert shells 27 is the same as the number of return channels 14. Through the above arrangement, the coolant is ensured to flow stably in the return channel 14. This design not only improves cooling efficiency but also reduces coolant loss and lowers operating costs.

[0018] Workflow: During installation, align the first insert shell 24 and the second insert shell 27 fixed at the bottom of the hood body 21 with the liquid inlet channel 12 and return channel 14 opened on the hood body 11, so that multiple first insert shells 24 are inserted into the liquid inlet channel 12 respectively, and multiple second insert shells 27 are inserted into the return channel 14. The rubber sealing rings 25 fixed on the outer sides of the first insert shell 24 and the second insert shell 27 have the effect of sealing between the first insert shell 24 and the liquid inlet channel 12 and between the second insert shell 27 and the return channel 14, which can prevent the coolant from moving outward when delivering coolant. Then fix the bolts in the fixing screw holes 15 opened on the hood body 21 and the fixing screw holes 15 opened on the hood body 11, thereby completing the assembly of the hood body 11 and the hood body 21. The liquid inlet connector 23 is connected to the oil supply pipe, and the liquid outlet connector 26 is connected to the oil return pipe. During cooling, the oil pump is started, and the coolant is delivered to the interior of the annular expansion groove 22 through the inlet connector 23. Since the annular expansion groove 22 is annular, the coolant will be distributed to the interior of multiple first insert shells 24 through the annular expansion groove 22. After being delivered to their respective corresponding inlet channels 12 through the first insert shells 24, the coolant is delivered to the interior of the annular groove 28 through the inlet channel 12, the bend 13 and the return channel 14. After being concentrated in the annular groove 28, it is output to the return oil pipe through the outlet connector 26. During this period, when the coolant enters the interior of the annular expansion groove 22, the large space inside the annular expansion groove 22 can cool the hood body 21. At the same time, after the coolant enters the inlet channel 12 and the return channel 14, it will cool the hood body 11, thereby achieving the effect of cooling the hood body 11 and the hood body 21 at the same time. Based on the above principles, the device can simultaneously cool both the housing body 11 and the cover body 21. This cooling method does not require the investment of a large amount of cooling equipment, saving investment costs. Moreover, the cooling structure of the device not only facilitates the guidance during the assembly of the housing body 11 and the cover body 21, but also improves the assembly accuracy.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
