ABSTRACT:
Transport refrigeration apparatus including a condenser section containing an inverted U-shaped refrigerant condenser coil which defines a central opening which functions as a fan chamber having a vertically oriented air discharge side. A propeller fan is disposed in the central opening of the condenser coil which draws air through the condenser coil and discharges it through the vertically oriented discharge side of the opening. A metallic grille is disposed across the air discharge side of the central opening, with the grille having a plurality of horizontally spaced, vertically oriented louvers which straighten the discharge air flow in vertical planes and reduce short circuiting of the discharge air back into the condenser coil. The louvers are spaced by a dimension selected to enable the metallic grille to perform the function of a protective or safety grille across the fan chamber.
