The utility model high-strength and high-thermal-conductivity motor casing has the characteristics of good heat dissipation effect, high strength and high production efficiency, and is suitable for large-scale automated production in factories.

[0004] However, in the prior art, the outer shell is made by an integrated molding process, and an inner shell is arranged inside the outer shell. Although the heat dissipation performance is improved by utilizing the water channel on the inner shell, the nested structure of the outer shell and the inner shell increases the thickness of the motor casing and reduces the overall thermal conductivity of the motor casing, which is not conducive to the heat dissipation of the casing. Therefore, the present application provides a high-strength and high-thermal conductivity motor casing to meet the needs. Utility Model Content

In addition, by arranging the cooling pipe in a flat shape, the cooling pipe has a large contact area with the inner wall of the motor casing body and the internal space of the motor casing body, thereby improving the heat dissipation effect of the motor casing body. Therefore, on the basis of the high thermal conductivity of the motor casing body made of aluminum alloy itself, the heat dissipation performance of the motor casing body is enhanced.

[0019] By arranging reinforced end seats at both ends of the motor casing body and using multiple reinforcement rods to connect and fix a pair of reinforced end seats, since the reinforced end seats and reinforcement rods are made of steel or cast iron, the overall strength of the motor casing body is greatly improved, which can ensure that the motor casing body can operate stably after the motor accessories are assembled. The motor casing body is reinforced based on the reinforced end seats and reinforcement rods, so that the strength requirement of the motor casing body is reduced, and then the motor casing body can adopt a thin-wall design to improve the overall thermal conductivity of the motor casing body and improve the heat dissipation effect.

After the end of the reinforcement end seat 2 is covered with the end cover, the second nut 17 can be used to press the pair of end covers and the reinforcement end seat 2 toward the motor casing body 1, and the first nut 16 is used to support and limit the pair of reinforcement end seats 2 to prevent the pair of reinforcement end seats 2 from continuously approaching each other and causing damage to the motor casing body 1.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, a base 4 is horizontally arranged at the bottom of the reinforced end seat 2, and mounting ear blocks 12 are arranged at both ends of the base 4. A mounting plate 5 is connected between the two mounting ear blocks 12 located on the same side of the motor casing body 1, and a second mounting through hole 13 is opened on the mounting plate 5.

[0038] The working principle provided by the utility model is that when in use, by setting a cooling pipe 6 that is spirally attached to the inner wall of the motor casing body 1, cooling water is injected from the water injection pipe 8 and then discharged from the drain pipe 9. During the circulation of the cooling water along the cooling pipe 6, the heat of the motor casing body 1 and the inside of the motor casing body 1 can be quickly dissipated, thereby enhancing the heat dissipation performance of the motor casing body 1. In addition, by setting the cooling pipe 6 to a flat shape, the cooling pipe 6 has a larger contact area with the inner wall of the motor casing body 1 and the internal space of the motor casing body 1, thereby improving the heat dissipation effect of the motor casing body 1. By sleeved reinforcing end seats 2 at both ends of the motor casing main body 1, and using multiple reinforcing rods 3 to connect and fix a pair of reinforced end seats 2, wherein, after the end of the reinforced end seat 2 is covered with the end cover, the second nut 17 can be used to press the pair of end covers and the reinforced end seat 2 toward the motor casing main body 1, and the first nut 16 is used to support and limit the pair of reinforced end seats 2 to prevent the pair of reinforced end seats 2 from continuously approaching and causing damage to the motor casing main body 1, thereby improving the overall strength of the motor casing main body 1 and ensuring that the motor casing main body 1 can operate stably after the motor accessories are assembled. The motor casing main body 1 is reinforced based on the reinforced end seat 2 and the reinforcing rod 3, so that the strength requirement of the motor casing main body 1 is reduced, and then the motor casing main body 1 can adopt a thin-walled design to improve the overall thermal conductivity of the motor casing main body 1 and improve the heat dissipation effect.
