Abstract
An improved air pulse generator produces high frequency chest wall oscillations (HFCWO) and includes means for internal heat dissipation. Internal heat generated by an internal diaphragm motor is dissipated by having a portion of the air chamber associated with the diaphragm motor being comprised of metal, by shaping a support associated with the diaphragm motor to allow increased air circulation around the diaphragm motor and positioning a vent in the housing of the air pulse generator that maximizes the release of heat from the diaphragm motor. Internal heat generated by internal electronic circuitry on a control board is dissipated by a heatsink attached to the control board.
