Air stream mixing conduit in an air handling module
View Patent ↗An air handling module for the air conditioning system of a motor vehicle is provided, including a housing having a first portion defining a first path and a second portion defining a second path and a conduit having first and second ends and an enclosed passageway there between. The conduit is positioned within the housing such as to at least partially connect the first path and the second path adjacent to the second end of the conduit.
1. An air handling module for the air conditioning system of a motor vehicle, the module comprising:
a housing including a first portion defining a first path and a second portion defining a second path; and
a non-pivoting conduit including first and second ends and an undivided, unitary enclosed passageway therebetween, the conduit being positioned within the housing such that air in the first path passes through the passageway to the second end, and the housing directs air in the second path to pass over an outer surface of the conduit between the first end and the second end, the first path meeting the second path adjacent to the second end of the conduit.
2. An air handling module as in claim 1 , wherein the conduit defines an arcuate outer surface.
3. An air handling module as in claim 1 , wherein the enclosed passageway of the conduit defines a circular, oval or airfoil shaped cross-section.
4. An air handling module as in claim 1 , wherein the second end includes a centerpoint and the second path includes a central longitudinal axis generally intersecting the centerpoint.
5. An air handling module as in claim 4 , wherein the second end defies an outlet opening extending substantially completely across the second path.
6. An air handling module as in claim 1 , wherein the second path extends past the conduit in a second path direction and the second end includes an outlet opening extending across the second path at an orientation that is nonparallel with the second path direction.
7. An air handling module as in claim 1 , wherein the conduit defines a central longitudinal axis and the second end includes an outlet opening that extends across the central longitudinal axis of the conduit at an angle greater than 25 degrees and less than 65 degrees.
8. An air handling module as in claim 7 , wherein the angle is substantially equal to 45 degrees.
9. An air handling module as in claim 1 , wherein the first end and the second end of the conduit respectively define an inlet opening and an outlet opening that are unparallel to each other.
10. An air handling module as in claim 9 , wherein the inlet opening of the first end and the outlet opening of the second end define an angle with respect to each other that is greater than 25 degrees and less than 65 degrees.
11. An air handling module as in claim 10 , wherein the angle defined between the inlet and outlet openings is substantially equal to 45 degrees.
12. An air handling module as in claim 1 , further comprising a bleed passage located adjacent to the first end of the conduit and forming a fluid communication between the first path and the second path.
13. An air handling module as in claim 1 , wherein the first portion of the housing extends adjacent to a first temperature controlling device and the second portion of the housing extends adjacent to a second temperature controlling device.
14. An air handling module as in claim 13 , wherein the first temperature controlling device is an air heating device and the second temperature controlling device is an air cooling device.
15. A heating and cooling apparatus for the air conditioning system of a motor vehicle, the heating and cooling apparatus comprising:
a first temperature controlling device;
a second temperature controlling device; and
an air handling module having a first portion defining a first path and a second portion defining a second path, the first path adjacent to the first temperature controlling device and the second path adjacent to the second temperature device; and
a non-pivoting conduit including first and second ends and an undivided, unitary enclosed passageway therebetween, the conduit being positioned within the housing such that air in the first path passes through the passageway to the second end and the housing directs air in the second path to pass over an outer surface of the conduit between the first end and the second end, the first path meeting the second path adjacent to the second end of the conduit.
16. A heating and cooling apparatus as in claim 15 , wherein the conduit defines an arcuate outer surface.
17. A heating and cooling apparatus as in claim 15 , wherein the second end includes a centerpoint and the second path includes a central longitudinal axis generally intersecting the centerpoint.
18. A heating and cooling apparatus as in claim 17 , wherein the second end defines an outlet opening extending substantially completely across the second path.
19. A heating and cooling apparatus as in claim 15 , wherein the first end and the second end respectively define an inlet opening and an outlet opening that unparallel to each other.
20. A heating and cooling apparatus as in claim 19 , wherein inlet opening of the first end and the outlet opening of the second end define an angle with respect to each other that is greater than 25 degrees and less than 65 degrees.
21. A heating and cooling apparatus as in claim 20 , wherein the angle defined between the inlet and outlet openings is substantially equal to 45 degrees.
22. A heating and cooling apparatus as in claim 15 , further comprising a bleed passage located adjacent to the first end of the conduit and forming a fluid communication between the first path and the second path.
