Abstract
A laminar flow fan is adapted to fit into a the internal cavity of a fan housing (70). The fan comprises a stack of parallel disk elements (12, 14, 16, 18, 20, 22) mounted for rotation on a motor (40) with the diameters of the disk elements varying within the stack to more fully utilize the available internal space of the housing. Apparatus which uses such a fan as part of its forced air cooling system is also described.
