Abstract
A transport refrigeration unit for use with a transport trailer includes a structural framework mountable to a wall of the transport trailer, a condenser heat exchanger unit mounted to the structural framework, an evaporator housing separated from the condenser heat exchanger by a distance, and at least one condenser fan assembly positioned aft of the condenser heat exchanger unit and forward of the evaporator housing. The at least one condenser fan assembly includes a fan casing and a fan rotor rotatable relative to the fan casing about an axis. The fan rotor has a plurality of fan blades. A shroud is coupled to a radially outer end of the plurality of fan blades. The shroud includes an axially oriented protrusion extending from a distal end of the shroud towards the fan casing and a clearance is formed between the protrusion and the casing defining a convoluted flow path.
