The motor housing 1 is sleeved with the waterproof cooling tower motor. The interior of the motor housing 1 is hollow, with its upper and lower ends longitudinally penetrating the motor housing 1. In use, the motor housing 1 is sleeved with the waterproof cooling tower motor to be connected, and the position of the motor is fixed through the second mounting hole 3 on its surface. The motor is sleeved inside the motor housing 1, which facilitates its later operation.

[0026] The motor housing 1 has multiple first heat dissipation fins 11, second heat dissipation fins 13, and third heat dissipation fins 14 arranged around its periphery. The corners of the first heat dissipation fins 11, second heat dissipation fins 13, and third heat dissipation fins 14 are arc-shaped. In use, the periphery of the first heat dissipation fins 11, second heat dissipation fins 13, and third heat dissipation fins 14 are all arc-shaped. The arc-shaped design of the first heat dissipation fins 11, second heat dissipation fins 13, and third heat dissipation fins 14 makes them longer than the diamond-shaped design. The longer length increases the heat dissipation effect of the first heat dissipation fins 11, second heat dissipation fins 13, and third heat dissipation fins 14, reduces the occurrence of thermal failures in the motor inside the motor housing 1, and extends the service life of the motor inside the motor housing 1.

[0027] A junction box 5 is provided on the surface of the motor housing 1 on the third heat dissipation fin 14. During use, the hollow design of the junction box 5 is modified as follows: Figure 1 The enclosed design shown will wrap the connecting wires during use, reducing the probability of the wires coming into contact with the outside, thereby increasing the sealing, waterproofing and dustproofing of the connecting wires, reducing the failure caused by water ingress and transmission problems caused by dust cover. The junction box 5 has an internal slot 53, which is connected to the motor housing 1. The internal slot 53 is used to place the wires.

[0028] The first heat dissipation fins 11 are distributed in three groups on the outer periphery of the motor casing 1, the third heat dissipation fins 14 are distributed in one group on the outer periphery of the motor casing 1, the third heat dissipation fins 14 and the first heat dissipation fins 11 are distributed at equal angles outside the motor casing 1, the first heat dissipation fins 11 and the third heat dissipation fins 14 are arranged on the periphery of the motor casing 1, thereby increasing the heat dissipation performance of the motor casing 1 in use.

[0029] The second heat dissipation fins 13 are arranged in four groups on the outer periphery of the motor casing 1, the second heat dissipation fins 13 are arranged in the gaps between the third heat dissipation fins 14 and the first heat dissipation fins 11, thereby increasing the heat dissipation performance of the motor casing 1 in use.

[0030] The effect achieved by the whole embodiment one is that the motor casing 1 is connected with the waterproof cooling tower motor sleeve, and the position of the motor is fixed through the second mounting hole 3 on the surface of the motor casing 1. The motor sleeve is connected in the motor casing 1, which is convenient for later operation. The periphery of the first heat dissipation fins 11, the second heat dissipation fins 13 and the third heat dissipation fins 14 is arc-shaped design. The arc-shaped design of the first heat dissipation fins 11, the second heat dissipation fins 13 and the third heat dissipation fins 14 makes the length longer than that of the prismatic design. The longer length increases the heat dissipation effect of the first heat dissipation fins 11, the second heat dissipation fins 13 and the third heat dissipation fins 14, reduces the heat failure of the motor in the motor casing 1, prolongs the service life of the motor in the motor casing 1, and changes the hollow design of the junction box 5 to the closed design as shown in Figure 1 The closed design can wrap the connected wire in use, reduce the probability of contact between the wire and the outside, increase the sealing, waterproofness and dustproofness of the connected wire, reduce the failure caused by water entering the wire in use and the transmission problem caused by dust covering.
