The shell structure of the existing air suspension blower is made of stainless steel materials, the mass is heavy, the heat dissipation performance is poor, and in addition, the heat dissipation flow channel of the existing shell structure is not reasonable enough in arrangement, so that the heat dissipation performance of a motor is poor.

Disclosure of Invention

In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present application is how to provide an air suspension blower casing structure to reduce the weight of the whole machine and improve the heat dissipation performance of the whole machine through the arrangement of the casing heat dissipation flow channel.

In order to solve the technical problem, the utility model adopts the following technical scheme:

a shell structure of an air suspension blower comprises a shell body, wherein the shell body comprises a shell body, an end cover positioned at the front end of the shell body and a shell tail positioned at the rear end of the shell body, and the end cover, the shell body and the shell tail are made of cast aluminum materials; through holes are uniformly distributed at the round angle position of the joint of the end cover and the shell body, and the through holes penetrate through the circumferential position of the inner side of the end cover.

Like this, shell structure is cast the aluminium material, compares in traditional stainless steel material, and the whole ratio of aluminium system material is lighter and heat dispersion is good to be convenient for integrated into one piece, have good processing performance.

In the operation process of actual equipment, a heat dissipation flow channel is formed in the shell body, namely, the impeller compresses air to work, cooling air outside the equipment is driven to enter the inner side of the end cover through the through holes uniformly distributed in the circumferential direction, the cooling air entering the end cover can cool and supply air to a gas bearing installed in the end cover, the cooled air flows to the side of the fan along a gap between the rotating shaft and the motor, and meanwhile, heat generated by the operation of the motor is taken away. The fan is used for pumping the air in the motor to the outside and realizing the outward transmission of the air in the motor.

Wherein, the end cover, the shell body and the shell tail are integrally formed. Is convenient for production, processing and manufacturing.

Wherein, the outside circumference equipartition of shell body is provided with radiating rib. The radiating fins can increase the contact area of the shell and the external cooling gas, thereby effectively improving the radiating efficiency.

And the shell tail is uniformly provided with heat dissipation ports along the circumferential direction. The amount of cooling gas entering the shell can be effectively increased, and the overall heat dissipation effect of the shell is effectively improved.

Wherein, the shell is provided with a water-cooling inlet and a water-cooling outlet, a water-cooling channel communicated with the water-cooling inlet and the water-cooling outlet is arranged in the shell, and the water-cooling channel is arranged along the shell in a surrounding manner. Cooling water enters the motor housing through the water-cooling inlet, circulates in the water-cooling flow channel 14, carries away heat transferred by the motor, and is discharged from the water-cooling outlet.

In conclusion, the air suspension blower casing structure reduces the weight and the assembly difficulty of the whole machine, improves the heat dissipation performance of the motor through the arrangement of the casing heat dissipation flow channel, and optimizes the performance of the whole machine. The water-cooling and air-cooling channel integrated with the shell can take away the heat of the motor to the maximum extent, and the heat dissipation efficiency of the whole machine is greatly improved.
