REDUCING ACCUMULATION OF DUST PARTICLES ON A HEAT DISSIPATING ARRANGEMENT

摘要

A method and apparatus to reduce dust particles accumulated on one or more surfaces provisioned proximate to the pulsating fan. The surfaces may include a heat exchanger provisioned proximate to the pulsating fan and the blades of the pulsating fan or any other such surface. The pulsating fan may be rotated in a first direction for a first time duration and in a second direction for a second time duration. The dust particles that are accumulated on the one or more surfaces provisioned proximate to the pulsating fan is reduced while the pulsating fan is rotated in the second direction. The second direction of rotation is reverse to the first direction of rotation. The pulsating fan may comprise an axial fan or a centrifugal fan.
