Abstract

A heat exchanger assembly includes a first heat exchanger plate and a second heat exchanger plate each include an outer boundary edge. The heat exchanger assembly also includes a service plate configured to be coupled to the outer boundary edge of each of the first and second heat exchanger plates. The service plate includes multiple sections coupled together to form a single plate, wherein each section of the multiple sections is configured to be individually removed to provide access to a space between the first and second exchanger plates.

Claims (34)

1. A heat exchanger assembly for an air

handling unit, comprising:

a first heat exchanger plate and a second heat exchanger plate each including an outer boundary edge; and

at least one service plate configured to be coupled to the outer boundary edge of each of the first and second heat exchanger plates, wherein the service plate comprises a plurality of sections coupled together to form a single plate, wherein each section of the plurality of sections is configured to be individually removed without having to remove any of the other sections to provide access to a space between the first and second heat exchanger plates.

2. The heat exchanger assembly of claim 1 , wherein the first heat exchanger plate and the second heat exchanger plate each include a first edge and a second edge disposed opposite the first edge, wherein the first and second edges are separated by third and fourth edges, wherein the first and second heat exchanger plates converge toward each other along the third and fourth edges in a direction from the first edge to the second edge, and the at least one service plate is configured to be coupled to either the third edges or the fourth edges of the first and second heat exchanger plates.

3. The heat exchanger assembly of claim 2 , wherein the at least one service plate comprises a first service plate coupled to the third edges of the first and second heat exchanger plates and a second service plate coupled the fourth edges of the first and second heat exchanger plates.

4. The heat exchanger assembly of claim 3 , wherein the third edges and the fourth edges are respectively located at a first longitudinal end and a second longitudinal end of the heat exchanger assembly.

5. The heat exchanger assembly of claim 2 , wherein the at least one service plate decreases in width in the direction from the first edge to the second edge.

6. The heat exchanger assembly of claim 1 , wherein an amount of the space that is accessible via removal of sections of the plurality of sections is adjustable.

7. The heat exchanger assembly of claim 1 , wherein the at least one service plate comprises a triangular shape.

8. The heat exchanger assembly of claim 1 , wherein the plurality of sections comprise three sections.

9. The heat exchanger assembly of claim 1 , wherein adjacent sections of the plurality of sections are directly coupled to each other via fasteners extending through each of the adjacent sections.

10. The heat exchanger assembly of claim 1 , wherein a section of the plurality of sections overlaps and directly contacts a portion of an adjacent section to keep air flow from escaping from the space through the at least one service plate.

11. The heat exchanger assembly of claim 10 , wherein the section is coupled to the adjacent section via a fastener through the overlapped portion.

12. The heat exchanger assembly of claim 1 , wherein the heat exchanger assembly comprises an evaporator.

13. A service plate for a heat exchanger assembly of an air handling unit, comprising:

a plurality of sections coupled together to form a single plate, wherein each section of the plurality of sections is configured to be individually removed without having to remove any of the other sections to provide access to a space between a first heat exchanger plate and a second heat exchanger plate, wherein the first exchanger plate and the second heat exchanger plate each include an outer boundary edge; and

wherein the service plate is configured to be coupled to the outer boundary edge of each of the first and second heat exchanger plates.

14. The service plate of claim 13 , wherein the service plate is configured to be coupled to a longitudinal end of the heat exchanger assembly.

15. The service plate of claim 13 , wherein an amount of the space that is accessible via removal of sections of the plurality of sections is adjustable.

16. The service plate of claim 13 , wherein the service plate comprises a triangular shape.

17. The service plate of claim 13 , wherein adjacent sections of the plurality of sections are directly coupled to each other via fasteners extending through each of the adjacent sections.

18. The service plate of claim 13 , wherein a section of the plurality of sections overlaps and directly contacts a portion of an adjacent section to keep air flow from escaping from the space through the service plate.

19. The service plate of claim 18 , wherein the section is coupled to the adjacent section via a fastener through the overlapped portion.

20. The service plate of claim 13 , wherein each section of the plurality of sections is orientated in a vertical direction.

21. An air handling unit, comprising:

an A-shaped evaporator coil assembly having a first longitudinal end and a second longitudinal end; and

at least one service plate configured to be coupled to either the first longitudinal end or the second longitudinal end, wherein the at least one service plate comprises a plurality of sections coupled together to form a single plate, wherein each section of the plurality of sections is configured to be individually removed without having to remove any of the other sections to provide access to a space within the A-shaped evaporator coil assembly.

22. The air handling unit of claim 21 , wherein the at least one service plate comprises a first service plate coupled to the first longitudinal end and a second service plate coupled to the second longitudinal end.

23. The air handling unit of claim 21 , wherein an amount of the space that is accessible via removal of sections of the plurality of sections is adjustable.

24. The air handling unit of claim 21 , wherein the at least one service plate comprises a triangular shape.

25. The air handling unit of claim 21 , wherein the plurality of sections comprise three sections.

26. The air handling unit of claim 21 , wherein adjacent sections of the plurality of sections are directly coupled to each other via fasteners extending through each of the adjacent sections.

27. The air handling unit of claim 21 , wherein a section of the plurality of sections overlaps and directly contacts a portion of an adjacent section to keep air flow from escaping from the space through the at least one service plate, and the section is coupled to the adjacent section via a fastener through the overlapped portion.
