Abstract

A mesh panel for a heat exchanger system is provided. The mesh panel comprises a mesh body extending from an upper end to a lower end, the mesh body having an inlet side and an outlet side opposite the inlet side. The mesh body comprises a plurality of mesh wires arranged to form a mesh pattern defining a plurality of mesh openings between the mesh wires, and at least one penetrating mesh portion extending at least partly along a depth direction of the mesh body, the depth direction being normal to a plane extending between the upper and lower ends of the mesh body, the at least one penetrating mesh portion at least partly defining an air flow opening, the air flow opening having greater dimensions than each of the mesh openings.

First claim

What is claimed is:

1. A mesh panel for a heat exchanger system, the mesh panel comprising:
a mesh body extending from an upper end to a lower end, the mesh body having an inlet side and an outlet side opposite the inlet side, the mesh body comprising a plurality of mesh wires arranged to form a mesh pattern defining a plurality of mesh openings between the mesh wires, the mesh body comprising:
at least one penetrating mesh portion configured to deflect air flowing therethrough, the at least one penetrating mesh portion extending at least partly along a depth direction of the mesh body, the depth direction being normal to a plane extending between the upper and lower ends of the mesh body, the at least one penetrating mesh portion at least partly defining an air flow opening, the air flow opening having greater dimensions than each of the mesh openings,
each of the at least one penetrating mesh portion comprising:
an inlet end;
an outlet end distanced from the inlet end along the depth direction, wherein the outlet end defines the air flow opening; and
a side wall extending between the inlet end and the outlet end at least partly in the depth direction, wherein the side wall is configured to deflect air flowing through the penetrating mesh portion, wherein the side wall is a peripheral side wall defining a periphery of the at least one penetrating mesh portion, and wherein the peripheral side wall of the at least one penetrating mesh portion converges toward the outlet end.

2. The mesh panel of claim 1 , wherein the at least one penetrating mesh portion has a generally truncated conical shape.

3. The mesh panel of claim 1 , wherein the air flow opening defined by each of the at least one penetrating mesh portion is circular.

4. The mesh panel of claim 1 , wherein the air flow opening defined by each of the at least one penetrating mesh portion is polygonal.

5. The mesh panel of claim 1 , wherein:
the at least one penetrating mesh portion defines a first perimeter at the inlet end and a second perimeter at the outlet end; and
the first perimeter is greater than the second perimeter.

6. The mesh panel of claim 1 , wherein:
the at least one penetrating mesh portion comprises a plurality of penetrating mesh portions; and
at least some of the penetrating mesh portions are spaced apart from one another along a height direction of the mesh body, the height direction being normal to the depth direction.

7. The mesh panel of claim 1 , wherein the at least one penetrating mesh portion deflects air flowing through the air flow opening to cause turbulence thereof.

8. The mesh panel of claim 1 , wherein:
the mesh body comprises a plurality of mesh layers stacked with one another in the depth direction to form the mesh body; and
the air flow opening defined at least in part by the at least one penetrating mesh portion is defined in part by each of the mesh layers.

9. The mesh panel of claim 1 , wherein:
the mesh body has a first angled portion extending from the upper end and a second angled portion extending from the lower end to the first angled portion, the first and second angled portions being angled relative to one another; and
each of the at least one penetrating mesh portion is formed in one of the first angled portion and the second angled portion.

10. The mesh panel of claim 1 , wherein the mesh body has an undulating configuration such that the mesh body forms a plurality of undulations offset from another in a height direction of the mesh body, the height direction being normal to the depth direction.

11. A heat exchanger system comprising:
a frame;
at least one heat exchanger panel connected to the frame and configured to exchange heat with air flowing therethrough, the at least one heat exchanger panel having an inlet side and an outlet side, the at least one heat exchanger panel comprising:
a cooling coil for circulating fluid therein; and
a plurality of fins in thermal contact with the cooling coil, the fins being spaced from one another for air to flow therebetween and into an interior space of the heat exchanger system;

a fan assembly connected to the frame and comprising at least one fan, the at least one fan being rotatable about a fan rotation axis to pull air into the interior space through the at least one heat exchanger panel and evacuate heated air from the interior space through the fan assembly;
at least one mesh panel disposed on the inlet side of the at least one heat exchanger panel such that rotation of the at least one fan causes ambient air to flow subsequently through the at least one mesh panel, through the heat exchanger panel, and into the interior space, the at least one mesh panel comprising:
a mesh body extending from an upper end to a lower end, the mesh body having an inlet side and an outlet side opposite the inlet side, the mesh body comprising a plurality of mesh wires arranged to form a mesh pattern defining a plurality of mesh openings between the mesh wires, the mesh body comprising at least one penetrating mesh portion configured to deflect air flowing therethrough, the at least one penetrating mesh portion extending at least partly along a depth direction of the mesh body, the depth direction being normal to a plane extending between the upper and lower ends of the mesh body, the at least one penetrating mesh portion at least partly defining an air flow opening, the air flow opening having greater dimensions than each of the mesh openings, each of the at least one penetrating mesh portion comprising:
an inlet end;
an outlet end distanced from the inlet end along the depth direction, wherein the outlet end defines the air flow opening; and
a side wall extending between the inlet end and the outlet end at least partly in the depth direction, wherein the side wall is configured to deflect air flowing through the penetrating mesh portion; and

a water distribution system operable to spray water on the mesh panel to pre-cool ambient air flowing through the mesh panel.

12. The heat exchanger system of claim 11 , wherein the water distribution system comprises a conduit disposed between the at least one heat exchanger panel and the mesh panel, the water distribution system being operable to spray water from the conduit onto the mesh panel.

13. The heat exchanger system of claim 11 , wherein the heat exchanger system is a dry cooler.

14. The heat exchanger system of claim 11 , wherein the side wall is a peripheral side wall defining a periphery of the at least one penetrating mesh portion, and wherein the peripheral side wall of the at least one penetrating mesh portion converges toward the outlet end.

15. The heat exchanger system of claim 11 , wherein:
the at least one penetrating mesh portion comprises a plurality of penetrating mesh portions; and
