Problems solved by technology

[0007] 1. Under the normal operation of the first and second fan units 10 and 20, the cooling air can only be sucked in by the single air inlet of the first fan unit 10 on the air inlet side, so that the total air output of the cooling fan series modules is limited
[0008] 2. When the first fan unit 10 or the second fan unit 20 is operating abnormally, the blade speed of the first fan wheel 10 or the second fan wheel 20 is too low, which will reduce the driving wind of the second fan wheel 20 or the first fan wheel 10 efficiency, thereby affecting the overall cooling efficiency
[0009] 3. When the first fan unit 10 or the second fan unit 20 is operating abnormally, due to the difference in flow velocity at the first fan wheel 10 and the second fan wheel 20, uneven airflow density occurs, resulting in the cooling fan series module The Static pressure-flow rate characteristic (P-Qcharacteristic) is low and produces a lot of wind shear noise

Abstract

A serial radial fan modular set is used for increasing cold air volume with uniform air density and little noise. It consists of a first fan unit and a second fan unit combined together. The first fan unit is located at the inlet side and the second one located at the outlet. A side opening, at least, is arranged on the wall near the connecting portion of the frames of the both fan units to increase air volume.
