As shown in Figures 1-2, a cooling system for a magnetically suspended single-stage high-speed blower includes a blower body 1, a housing 2, a passive heat dissipation mechanism and an active heat dissipation mechanism;

The blower body 1 is arranged in the casing 2, the blower body 1 includes a current collector 101, a volute 102, a connecting plate 103 and a motor body 104, the current collector 101 is connected with the volute 102, The volute 102 is connected with the motor body 104 through the connecting plate 103, and the motor body 104 is provided with a cooling coil (not shown in the figure);

The tail end side of the motor body 104 on the side wall of the housing 2 is provided with an air inlet, and the passive heat dissipation mechanism is arranged at the air inlet, and the passive heat dissipation mechanism includes a first radiator 5 and a housing filter. 6, the first radiator 5 and the housing filter 6 are fixedly connected to the housing, and the housing filter 6 and the first radiator 5 are sequentially arranged along the air intake direction;

The active heat dissipation mechanism includes an active heat dissipation channel 3 isolated from the housing 2, the active heat dissipation channel 3 is arranged perpendicular to the axial direction of the motor body 104, and the active heat dissipation channel 3 is provided with an axial flow fan 10, The second radiator 11 and the channel filter 12, the axial flow fan 10 and the channel filter 12 are respectively arranged at the two ends of the active cooling channel 3, and the second radiator 11 is arranged between the axial flow fan 10 and the channel between filters 12;

It also includes a refrigeration mechanism that provides cooling liquid for the passive heat dissipation mechanism, the active heat dissipation mechanism and the cooling coil. The engine 9, the cooling liquid tank 8, the pump 7, the first radiator 5, the second radiator 11 and the cooling coil are connected in sequence through the guide pipe to form a circulation loop.

A partition 4 is arranged at the side of the first radiator 5 close to the tail end of the motor body 104, and the surroundings of the partition 4 are fixedly connected with the housing 2 through the support, and the surroundings of the partition 4 are connected with the housing 2. There is a gap between them, so that the air needs to bypass the partition 4 after entering the shell 2. This arrangement can improve the heat exchange efficiency while ensuring the air intake.

The air inlet of the casing 2 is set opposite to the side where the current collector 101 is located, which ensures that the airflow in the casing 2 flows from the tail side of the motor body 104 to the front end of the motor body 104, and avoids local temperature rise in the casing 2.

The air inlets of the first radiator 5 and the housing filter 6 have the same cross-sectional area and are arranged facing each other, which ensures that the air intake of the housing 2 passes through the first radiator 5 greatly.

The air inlets of the second radiator 11 and the channel filter 12 have the same cross-sectional area and are arranged facing each other, which ensures that the active cooling channel 3 passes through the second radiator 11 with a large amount of air.

The active cooling mechanism is arranged above the motor body 104, and the refrigeration mechanism is arranged below the motor body 104, which has a compact structure and a small footprint.

Both the first radiator 5 and the second radiator 11 are plate heat exchangers with good heat exchange effect.

The refrigeration mechanism is isolated from the housing 2, and the refrigeration temperature is set to ensure that the motor can operate normally even in a high temperature environment.

Coolant is water, antifreeze or oil, widely used and readily available.

When the heat exchange of the second radiator 11 cannot meet the cooling temperature, first start the axial flow fan 10, so that the air outside the housing is filtered through the channel filter 12, and then passes through the second radiator 11, thereby increasing the heat dissipation area of the system, Since the active heat dissipation channel 3 is independent, the heat here can be discharged out of the casing along with the airflow, so as to prevent the temperature in the casing from being too high and affect the efficiency of the fan; the channel filter 12 can purify the air and prevent the second radiator 11 from accumulating dust and affecting heat dissipation.

The control method of this system is: set two temperature thresholds for the motor, which are T1 and T2 respectively, and T1<T2. When the motor runs at T1 temperature for a long time, the radial motion trajectory of the motor will become larger, and the motor will run at T2 temperature for a long time. It will cause trajectory disorder. During the temperature rise of the motor: when the temperature of the motor reaches T1, the axial fan 10 is turned on, and the refrigerator 9 does not work; when the temperature of the motor rises to T2, both the axial fan 10 and the refrigerator 9 work. During the temperature drop of the motor, when the temperature t satisfies T1<t<T2, the axial flow fan 10 works and the refrigerator does not work; when the temperature drops below T1, neither the axial flow fan 10 nor the refrigerator works.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in the Within the protection scope of the present utility model.
