Compared with the energy tower which is not changed, the improved energy tower has the advantages that the noise of the energy tower is reduced when the fan of the energy tower runs, the integral vibration is reduced when a plurality of energy towers are combined, and the running is more stable. It has the following components:

1. the fan blade material made of hollow aluminum alloy reduces fan noise and is smaller than the blade noise of a stamped steel plate.

2. The number of blades of the fan is increased, and 6 blades are adopted. On the premise of obtaining the same air quantity, the rotating speed of the fan can be reduced, so that the noise of the fan is reduced.
