Integrated parallel heat dissipation device with single air outlet

Abstract

The invention provides an integrated parallel heat dissipation device with a single air outlet, and relates to the field of motors. One end of each volute (2) of the integrated parallel heat dissipation device is totally closed; the other end of each volute (2) is provided with an air inlet and an inlet of an impeller (3); a male end of each male flange (8) and the other end of the corresponding volute (2) are positioned in a matched manner via a seam and are connected with each other by a bolt; shaft extension portions on two sides of a motor (4) are respectively connected with a shaft sleeve of the impeller (3) via flat keys and are fastened via locking nuts (1); the size of a double-air-inlet opening in the upper end of an air guiding base (5) is equal to the sizes of air outlets in the lower ends of the two volutes (2); and the double-air-inlet opening in the upper end of the air guiding base (5) and the air outlets in the lower ends of the two volutes (2) are respectively connected with other bolts by flanges. The integrated parallel heat dissipation device with the single air outlet has the advantages of simple structure, energy conservation, noise reduction, high air volume, high air pressure and the like.

Description

technical field [0001] The patent of the present invention relates to the field of motors, and is an integrated parallel single-outlet cooling device for motor heat dissipation. Background technique [0002] Existing heat dissipation devices generally use ordinary centrifugal fans installed on the top of either end of the motor to forcibly cool the motor. Ordinary centrifugal fans have large noise, large vibration, large volume, small air volume, and low air pressure, which cannot adapt to the development of modern industry at all. . [0003] The existing heat dissipation devices generally adopt ordinary centrifugal fans, and most of their structures and shapes are figure 1 As shown, its defects have the following points: [0004] a. The driving motor of the ordinary centrifugal fan is installed on the volute with a single shaft at 90° and cantilevered on a single flange. The selected motor is an ordinary series motor with large noise and vibration, which cannot meet the n...

Problems solved by technology

[0004] a. The driving motor of the ordinary centrifugal fan is installed on the volute with a single shaft at 90° and cantilevered on a single flange. The selected motor is an ordinary series motor with large noise and vibration, which cannot meet the noise limit of the frequency conversion high-speed motor at all. And the vibration limit, the motor bearing will be burned due to the resonance transmitted by the centrifugal fan;
