Abstract
A cooling fan shroud comprises multiple, functionally identical sections that form a ring-like structure that completely surrounds the fan when the shroud is installed onto an aperture plate or other structure. The shroud makes the cooling system more efficient by improving air flow at a given fan speed by reducing fan tip clearance, and increasing air flow due through the fan. An alternative, single piece shroud is also provided which can be retrofitted to an existing cooling system.
