Feasibility and Design Study of a Frictionless Air Mover for Thermal Management of Electronics

  • A frictionless air mover concept will be introduced. As opposed to a piezoelectric driven fan, the air mover is based on a flexible blade whose vibration is driven by means of a magnetic field. The blade material is based on a polymer material. The paper presents the results of feasibility and an on-going comprehensive design study. The results are compared with a comparable piezoelectric fan [1, 2]. The performance of the feasibility study amounted to 65% to the piezoelectric fan. To enhance the performance, two different blade materials as well as the influence of the coil shape and value were under investigation. A further goal is to reduce the size and to investigate the influence of a cabinet. The design study results in a prototype of a size of 50 x 14 x 35 mm² incl. a cabinet. The performance could be doubled. A volume flow rate of V̊ ~14 l/min and static pressure of Ƿstat = 3 Pa could be reached.
