Kind Code:
A1
Abstract:
Provided are a willow catkin prevention system for a cooling apparatus, and a data center cooling system. The willow catkin prevention system comprises: an intercepting device, a fan and a differential pressure sensor, wherein the intercepting device is arranged at an air inlet of an air duct of a cooling apparatus and is used for intercepting willow catkins outside the air duct; the fan is arranged inside the air duct; the differential pressure sensor is arranged between the fan and the intercepting device and is used for measuring the differential pressure between the inside and outside of the air duct; the fan is connected to a three-phase power source by means of a control circuit; the control circuit comprises a first three-phase line branch and a second three-phase line branch, which are arranged in parallel; the first three-phase line branch is connected to the three-phase power source and the fan in a positive sequence and is used for controlling the fan to rotate forwards; and the second three-phase line branch is connected to the three-phase power source and the fan in a negative sequence and is used for controlling the fan to rotate reversely. In the willow catkin prevention system for a cooling apparatus, and the data center cooling system provided in the present application, blockage of debris caused by willow catkins at the air inlet of the cooling apparatus can be cleared.
