    Abstract: A flow chamber having an upper chamber, a lower chamber, and an actuator is described. The upper chamber includes a top wall. The actuator is located distally from the top wall. The lower chamber includes a bottom wall and a sidewall. The lower chamber receives a fluid from the upper chamber when the actuator is activated. The bottom wall has orifices and at least one cavity therein. The orifices are vertically aligned with a portion of the actuator and allow the fluid to exit the lower chamber. The at least one cavity is proximate to the sidewall and distally located from the orifices.

    Abstract: A heat transfer system includes fluid transfer cells that vibrationally move a fluid and a thermally conductive cover that conducts heat from the cells while avoiding transfer of mechanical energy between the cells. A fluid transfer module includes outer and inner walls, a support member, and a membrane. The outer wall has an outer opening. The inner wall has an inner opening. The support member is disposed laterally on the inner wall such that a flow chamber is defined between the outer and inner walls. The membrane is supported by the support member along the outer wall. A fluid transfer module includes an inlet port and an actuator. The actuator undergoes vibrational motion and has first and second vibrational modes. The first vibrational mode causes fluid to enter the inlet port. The second vibrational mode expels fluid from the inlet port, which reduces clogging of the inlet port.
