Abstract
An exhaust device applied to an electronic device is described. Memory deformable elements of the exhaust device are heated to shrink, and meanwhile, guide vanes located on an air outlet are driven to rotate and swing back and forth between a left outlet position and a right outlet position, such that the exhaust device reciprocatively changes an outlet position without requiring any external power.
