Abstract

A heat exchanger assembly includes: a frame; a heat exchanger panel mounted to the frame and configured to exchange heat with air flowing therethrough, the heat exchanger panel being disposed at an inclined orientation; a fan assembly disposed vertically above the heat exchanger panel; and a sound dampening device disposed within an interior space of the heat exchanger assembly such that air is pulled into the interior space through the heat exchanger panel and then flows through the sound dampening device before being discharged from the heat exchanger assembly via the fan assembly. The sound dampening device includes baffle members having sound absorbing material and spaced apart from one another for allowing air flow therebetween. Each baffle member extends at an angle relative to a plane extending through the upper and lower ends of the heat exchanger panel so as to direct air flow upwardly toward the fan assembly.

First claim

What is claimed is:

1. A heat exchanger assembly, comprising:
a frame;
a heat exchanger panel mounted to the frame and configured to exchange heat with air flowing therethrough, the heat exchanger panel having a lower end and an upper end, the heat exchanger panel being disposed at an inclined orientation such that the upper and lower ends thereof are offset from one another, the heat exchanger panel comprising:
a tubing arrangement for circulating fluid therein; and
a plurality of fins in thermal contact with the tubing arrangement, the fins being spaced apart from one another for air to flow therebetween and into an interior space of the heat exchanger assembly;

a plurality of enclosing panels connected to the frame and defining in part the interior space of the heat exchanger assembly;
a fan assembly disposed vertically above the heat exchanger panel, the fan assembly comprising a fan impeller rotatable about a fan rotation axis to pull air into the interior space of the heat exchanger assembly through the heat exchanger panel and evacuate heated air upwardly from the interior space of the heat exchanger assembly through the fan assembly; and
a sound dampening device disposed within the interior space of the heat exchanger assembly such that air is pulled into the interior space through the heat exchanger panel and then flows through the sound dampening device before being discharged from the heat exchanger assembly via the fan assembly, the sound dampening device comprising:
a plurality of baffle members, the baffle members being spaced apart from one another for allowing air flow therebetween, each of the baffle members extending at an angle relative to a plane extending through the upper and lower ends of the heat exchanger panel so as to direct air flow upwardly toward the fan assembly,
wherein:
each of the baffle members has a first portion and a second portion extending from the first portion;
the first portion is positioned closer to the heat exchanger panel than the second portion such that air pulled into the heat exchanger assembly and flowing through the sound dampening device traverses along the first portion of each of the baffle members before reaching the second portion thereof; and
the second portion extends upwardly at an angle relative to the first portion to deflect air flow incoming from a direction of the first portion.

2. The heat exchanger assembly of claim 1 , wherein the second portion of each baffle member extends generally vertically.

3. The heat exchanger assembly of claim 1 , wherein the first portion of each baffle member extends at an angle between 40° and 75° inclusively relative to a horizontal plane.

4. The heat exchanger assembly of claim 1 , wherein a spacing between consecutive ones of the baffle members is variable.

5. The heat exchanger assembly of claim 1 , wherein:
each of the baffle members has an upper end and a lower end; and
the lower end of a given one of the baffle members is positioned vertically lower than the upper end of a consecutive one of the baffle members positioned below the given one of the baffle members.

6. The heat exchanger assembly of claim 1 , wherein:
the baffle members are first baffle members;
the sound dampening device further comprises:
a plurality of second baffle members affixed to the first baffle members, the second baffle members extending perpendicular to the first baffle members and to the plane extending through the upper and lower ends of the heat exchanger panel, the second baffle members being spaced apart from one another, the first baffle members and the second baffle members forming air ducts therebetween.

7. The heat exchanger assembly of claim 6 , wherein the first baffle members and the second baffle members form a rectangular grid defining the air ducts.

8. The heat exchanger assembly of claim 6 , wherein each of the second baffle members has a generally triangular shape.

9. The heat exchanger assembly of claim 8 , wherein, each of the second baffle members comprises:
a first edge;
a second edge extending perpendicularly to the first edge; and
a third edge extending diagonally relative to the first and second edges,
the third edge being adjacent to the heat exchanger panel.

10. The heat exchanger assembly of claim 6 , wherein a spacing between consecutive ones of the second baffle members is variable.

11. The heat exchanger assembly of claim 1 , further comprising:
a plurality of acoustic panels connected to the enclosing panels for acoustically insulating the interior space of the heat exchanger assembly.

12. The heat exchanger assembly of claim 1 , wherein:
the heat exchanger panel is a first heat exchanger panel;
the fan assembly is a first fan assembly, and the fan rotation axis is a first fan rotation axis;
the sound dampening device is a first sound dampening device; and
the heat exchanger assembly further comprises:
a second heat exchanger panel mounted to the frame and configured to exchange heat with air flowing therethrough, the second heat exchanger panel having a lower end and an upper end, the second heat exchanger panel being disposed at an inclined orientation such that the upper and lower ends thereof are offset from one another, the first and second heat exchanger panels being disposed in a V-configuration such that a distance between the upper ends of the first and second heat exchanger panels is greater than a distance between the lower ends of the first and second heat exchanger panels, the second heat exchanger panel comprising:
a tubing arrangement for circulating fluid therein; and
a plurality of fins in thermal contact with the tubing arrangement of the second heat exchanger panel, the fins of the second heat exchanger panel being spaced apart from one another for air to flow therebetween and into the interior space of the heat exchanger assembly;

a second fan assembly disposed vertically above the second heat exchanger panel, the second fan assembly comprising:
a fan impeller rotatable about a second fan rotation axis to pull air into the interior space of the heat exchanger assembly through the second heat exchanger panel and evacuate heated air upwardly from the interior space of the heat exchanger assembly through the second fan assembly;

and
a second sound dampening device disposed within the interior space of the heat exchanger assembly such that air is pulled into the interior space through the second heat exchanger panel and then flows through the second sound dampening device before being discharged from the heat exchanger assembly via the second fan assembly, the second sound dampening device comprising:
a plurality of baffle members, the baffle members of the second sound dampening device being spaced apart from one another for allowing air flow therebetween, each of the baffle members of the second sound dampening device extending at an angle relative to a plane extending through the upper and lower ends of the second heat exchanger panel so as to direct air flow upwardly toward the second fan assembly.

13. The heat exchanger assembly of claim 12 , wherein the frame comprises:
a first leg and a second leg laterally spaced apart from the first leg;
at least one lower transversal member extending laterally and interconnecting the first and second legs;
