Condenser unit with fan

1. A heating, ventilating, and air conditioning (HVAC) system, comprising:

a fan configured to direct air within the HVAC system, comprising:

a plurality of blades coupled to a hub, wherein each blade of the plurality of blades comprises a leading edge;

a shroud fixed to the plurality of blades, wherein the shroud comprises a plurality of openings formed about a circumference of the shroud, wherein the shroud is configured to rotate with the plurality of blades to focus a flow of air along a rotational axis of the fan and reduce the flow of the air radially outward from the fan; and

a plurality of winglets, wherein each winglet of the plurality of winglets extends from a respective leading edge of a respective blade of the plurality of blades and is configured to direct air radially inward through a respective opening of the plurality of openings to the respective blade of plurality of blades, and wherein each winglet of the plurality of winglets extends radially outward from the shroud.

2. The system of the claim 1 , wherein the shroud extends about an entire circumference of the fan.

3. The system of claim 1 , wherein a height of the shroud varies about a circumference of the fan.

4. The system of claim 1 , wherein each blade of the plurality of blades comprises a wing swept blade.

5. The system of claim 1 , wherein the plurality of blades comprises three blades.

6. The system of claim 1 , wherein the shroud defines a first height at the respective leading edge of each blade of the plurality of blades and a second height at a respective trailing edge of each blade of the plurality of blades, and wherein the first height is greater than the second height.

7. The system of claim 1 , wherein each blade of the plurality of blades defines a first length at the leading edge and a second length at a respective trailing edge of the blade, and wherein the first length is greater than the second length.

8. The system of claim 1 , wherein the leading edge defines a curved leading edge.

9. The system of claim 1 , wherein each blade of the plurality of blades continuously curves between the leading edge and a respective trailing edge of the blade.

10. The system of claim 1 , wherein the plurality of blades and the shroud are a single piece.

11. The system of claim 1 , comprising a condenser unit having the fan.

12. A condenser system, comprising:

a fan configured to draw a fluid through a heat exchanger and eject the fluid from the condenser system, wherein the fan comprises:

a plurality of blades coupled to a hub;

an axial shroud fixed to the plurality of blades, wherein the axial shroud extends about an entire circumference of the fan and comprises a plurality of openings, and wherein the axial shroud is configured to rotate with the plurality of blades and to focus a flow of the fluid along an axis of the fan and reduce the flow of the fluid radially outward from the fan; and

a plurality of winglets, wherein each winglet of the plurality of winglets extends radially outward from the axis of the fan and from the axial shroud and is configured to direct air radially inward through a respective opening of the plurality of openings into the fan.

13. The system of claim 12 , wherein a height of the axial shroud changes about the circumference of the fan.

14. The system of claim 12 , wherein the axial shroud defines a first height at a respective leading edge of each blade of the plurality of blades and a second height at a respective trailing edge of each blade of the plurality of blades, and wherein the first height is greater than the second height.

15. The system of claim 12 , wherein each blade of the plurality of blades defines a first length at a respective leading edge and a second length at a respective trailing edge, and wherein the first length is greater than the second length.

16. A fan configured to draw a fluid through a heat exchanger and eject the fluid from a condenser unit, wherein the fan comprises:

a plurality of blades coupled to a hub;

a shroud fixed to the plurality of blades, wherein the shroud comprises one or more openings, and wherein the shroud is configured to rotate with the plurality of blades and focus a flow of the fluid along an axis of the fan and reduce the flow of the fluid radially outward from the fan; and

a winglet coupled to the shroud and extended radially outward from the axis of the fan and from the shroud, wherein the winglet is configured to force the fluid radially inward into the one or more openings of the shroud.

17. The fan of claim 16 , wherein the shroud defines a first height at a respective leading edge of each blade of the plurality of blades and a second height at a respective trailing edge of each blade of the plurality of blades, and wherein the first height is greater than the second height.

18. The fan of claim 16 , wherein the plurality of blades comprises wing swept blades.

19. The fan of claim 16 , wherein each blade of the plurality of blades defines a first length at a respective leading edge and a second length at a respective trailing edge, and wherein the first length is greater than the second length.
