A refrigerating unit including a base, a heat exchanger, and a shroud attached to the base The heat exchanger may have opposite side edges defined by a pair of substantially cylindrical headers, at least one of the headers having an inlet tube or an outlet tube extending, and a substantially rectangular shroud attached to the base and being provided with notched corners. The shroud has a top surface with at least one elongate boss, and integrally-formed resilient gripping portions which capture the heat exchanger headers. The heat exchanger is mounted to the base through engagement with the shroud, clearance is provided between a shroud notched corner and the inlet or outlet tube, and the boss provides a means for supporting the shroud when placed upside down.

What is claimed is: 1. A refrigerating unit comprising: a base, said base including a compressor mounted thereon; a heat exchanger through which air passes, wherein said heat exchanger has opposite side edges; and an air-directing shroud attached to said base, wherein said shroud has a plurality of elastically deformable gripping portions, said gripping portions independently gripping said heat exchanger, each of said heat exchanger side edges being engaged with at least one of said shroud gripping portions, said heat exchanger being mounted to said base through the engagement of said heat exchanger and said shroud, said elastically deformable gripping portions each comprising a cantilever extending from said shroud, said cantilever having a proximal end portion attached to said shroud and a distal end portion free to move with respect to said proximal end portion. 2. The refrigerating unit of claim 1, wherein said gripping portions are integrally formed with said shroud. 3. The refrigerating unit of claim 1, wherein said shroud is provided with integrally formed indicia which are visible after said shroud and heat exchanger have been attached to said base. 4. The refrigeration unit of claim 1, wherein said shroud has a top surface provided with at least one elongate boss, said at least one boss providing a means for supporting said shroud when placed upside down prior to said shroud being attached to said base, wherein said shroud is supportable solely by said at least one boss when said shroud is placed upside down during assembly of said refrigerating unit. 5. The refrigerating unit of claim 4, wherein said at least one elongate boss provides a means for supporting said shroud and said heat exchanger when said shroud and said heat exchanger are engaged, and when said shroud and said heat exchanger are placed upside down prior to said shroud being attached to said base. 6. The refrigeration unit of claim 1, further including a pair of headers which define said opposite side edges, each said header being captured within at least one said gripping portion, each said header having an outer surface which is substantially cylindrical, and each said gripping portion having an inner surface which is substantially cylindrical and interfaces with a said header substantially cylindrical outer surface, respective ones of said interfacing surfaces being substantially in surface contact with each other. 7. The refrigeration unit of claim 1, further including a pair of headers which define said opposite side edges, each said header being captured within at least one said gripping portion, said headers having a cross-sectional geometry substantially inscribable within a circle, said gripping means substantially enveloping at least 180 degrees of said circle. 8. The refrigeration unit of claim 1, said base having at least one recess, said shroud having at least one projection engaging said at least one recess. 9. A refrigerating unit comprising: a base, said base including a compressor mounted thereon; a heat exchanger through which air passes, wherein said heat exchanger has opposite side edges; a pair of headers which define said heat exchanger opposite side edges; and an air-directing shroud attached to said base, wherein said shroud has a plurality of gripping portions, said headers being captured within said shroud gripping portions wherein said heat exchanger is engaged with said shroud, said heat exchanger being mounted to said base through the engagement of said heat exchanger and said shroud. 10. The refrigerating unit of claim 9, wherein each said heat exchanger header has an outer surface which is substantially cylindrical, and each said shroud gripping portion has an inner surface which is substantially cylindrical and interfaces with a said header substantially cylindrical outer surface, respective ones of said interfacing surfaces being substantially in surface contact with each other. 11. The refrigerating unit of claim 10, wherein a said header outer surface and a said shroud gripping portion inner surface are substantially coaxial. 12. The refrigeration unit of claim 9, said headers having a cross-sectional geometry substantially inscribable within a circle, said gripping means enveloping at least 180 degrees of said circle. 13. A refrigerating unit comprising: a base; a heat exchanger through which air passes; and an air-directing shroud attached to said base, said heat exchanger being engaged with said shroud, said heat exchanger being mounted to said base through the engagement of said heat exchanger and said shroud wherein said shroud is substantially rectangular and is provided with a plurality of notched corners, and said heat exchanger has opposite side edges and is provided with one of an inlet tube and an outlet tube located near an end of a said side edge, a said notched corner providing a notched corner edge which partially surrounds said inlet or outlet tube, clearance being provided between said shroud notched corner edge and said heat exchanger inlet or outlet tube. 14. The refrigerating unit of claim 13, wherein each corner of said substantially rectangular shroud is notched, whereby a said heat exchanger inlet or outlet tube provided near either end of either of said opposite side edges is provided with clearance to said shroud. 15. The refrigerating unit of claim 13, wherein said heat exchanger opposite side edges are defined by a pair of headers about which said heat exchanger is gripped by elastically deformable portions of said shroud. 16. The refrigerating unit of claim 15, wherein said heat exchanger headers and said shroud elastically deformable portions have substantially cylindrical interfacing surfaces. 17. A condensing unit comprising: a base; a heat exchanger through which air passes, said heat exchanger having opposite side edges defined by a pair of substantially cylindrical headers, said heat exchanger having an inlet tube and an outlet tube, at least one of said headers having one of said inlet tube and said outlet tube extending from a side surface of said header near one end of said header; and a substantially rectangular air-directing shroud attached to said base and being provided with a plurality of notched corners, each said notched corner forming a notched corner edge, said shroud having a top surface which is provided with at least one elongate boss, said shroud having a plurality of integrally-formed resilient gripping portions which surround and capture said heat exchanger headers, whereby said heat exchanger and said shroud are engaged, wherein said heat exchanger is mounted to said base through the engagement of said heat exchanger and said shroud, clearance is provided between said shroud notched corner edge and said heat exchanger inlet or outlet tube, and said at least one boss provides a means for supporting said shroud when placed upside down prior to said shroud being attached to said base.
