Abstract

A heat exchanger unit that includes a frame and an at least one cooler coupled therewith. The heat exchanger unit has a reference axis. The heat exchanger unit includes an airflow region therein. The heat exchanger unit includes an at least one baffle coupled to the frame within the airflow region. The at least one baffle is configured at an angle to the axis.

Claims (58)

1. A heat exchanger unit, comprising:

an axis;

a frame;

an at least one cooler coupled with the frame;

a fan coupled to the frame;

an airflow region within the heat exchanger unit; and

a first set of baffles coupled to the frame within the airflow region, an at least one baffle of the first set of baffles oriented at a first angle to the axis,

wherein a mid-point of an at least one of the first set of baffles is positioned approximately a multiple of a quarter wavelength below the fan, the quarter wavelength being calculated based on a dominant acoustic frequency generated by the fan.

2. The heat exchanger unit of claim 1 , the unit further comprising:

a second set of baffles, each baffle of the second set of baffles configured at a second angle to the axis; and

a third set of baffles, each baffle of the third set of baffles configured at a third angle to the axis.

3. The heat exchanger unit of claim 2 , wherein the first set of baffles, the second set of baffles, and the third set of baffles each comprise between three and five baffles, and wherein each baffle of the first set of baffles, the second set of baffles, and the third set of baffles comprises a sound absorbing material.

4. The heat exchanger unit of claim 3 , wherein the sound absorbing material reduces the point source dominant acoustic frequency by at least 10 dB, and wherein each of the first angle, second angle, and third angle is in the range of about 30 degrees to about 60 degrees.

5. The heat exchanger unit of claim 3 , the unit further comprising:

a fan mount bar;

a shroud; and

an aeroring;

wherein the fan is mounted to the fan mount bar, the fan further comprising a motor and a plurality of fan blades.

6. The heat exchanger unit of claim 3 , wherein the at least one cooler is configured to permit airflow to pass therethrough, and wherein operation of the fan results in airflow through the at least one cooler, into the airflow region, and out of an exhaust outlet.

7. The heat exchanger unit of claim 3 , wherein the first angle, the second angle, and the third angle are substantially the same.

8. The heat exchanger unit of claim 3 , wherein the frame further comprises a plurality of horizontal members and vertical members configured together in a manner that results in a cube-shaped frame.

9. A heat exchanger unit, comprising:

an axis;

a frame;

an at least one cooler coupled with the frame, the at least one cooler having an outer surface and an inner surface;

a fan coupled to the frame; and

a first set of baffles coupled with the frame, at least one baffle of the first set of baffles oriented at a first angle to the axis,

wherein the first set of baffles are positioned approximately a multiple of a quarter wavelength below the fan, the quarter wavelength being calculated based on a dominant acoustic frequency generated by the fan.

10. The heat exchanger unit of claim 9 , the unit further comprising:

a second set of baffles, each baffle of the second set of baffles configured at a second angle to the axis; and

a third set of baffles, each baffle of the third set of baffles configured at a third angle to the axis.

11. The heat exchanger unit of claim 10 , wherein the first set of baffles, the second set of baffles, and the third set of baffles each comprise between two and four baffles, and wherein each baffle of the first set of baffles, the second set of baffles, and the third set of baffles comprises a sound absorbing material.

12. The heat exchanger unit of claim 11 , wherein the sound absorbing material reduces the point source dominant acoustic frequency by at least 10 dB, and wherein each of the first angle, second angle, and third angle is in the range of 30 degrees to 60 degrees.

13. The heat exchanger unit of claim 10 , wherein the first angle, the second angle, and the third angle are substantially the same.

14. The heat exchanger unit of claim 9 , the unit further comprising:

a fan mount bar;

a shroud; and

an aeroring;

wherein the fan is mounted to the fan mount bar, the fan further comprising a motor and a plurality of fan blades in the range of 8 to 12 blades, and an exhaust outlet.

15. The heat exchanger unit of claim 14 , wherein the at least one cooler is configured to permit airflow to pass therethrough, and wherein operation of the fan results in airflow through the at least one cooler.

16. The heat exchanger unit of claim 15 , wherein the frame further comprises a plurality of horizontal members and vertical members configured together in a manner that results in a cube-shaped frame.

17. A heat exchanger unit, comprising:

an axis;

a frame comprising a top region, a bottom region, and a plurality of side regions;

a plurality of coolers, each of the plurality of coolers coupled with the frame proximate to a respective side region of the plurality of side regions;

a fan; and

a first set of baffles, an at least one baffle of the first set of baffles configured at a first angle to the axis, and comprising a sound absorbing material,

wherein at least a portion of the at least one baffle of the first set of baffles is proximately positioned a multiple of a quarter wavelength below the fan, the quarter wavelength being calculated based on a dominant acoustic frequency generated by the fan during operation.

18. The heat exchanger unit of claim 17 , the unit further comprising:

a second set of baffles, each of the second set of baffles configured at a second angle to the axis; and

a third set of baffles, each of the third set of baffles configured at a third angle to the axis wherein each of the first angle, the second angle, and the third angle are in the range of 30 degrees to 60 degrees.

19. The heat exchanger unit of claim 17 , the heat exchanger unit further comprising:

a mount assembly for coupling an at least one of the plurality of coolers to the frame, the mount assembly further comprising:

an elongated fastening member;

a rigid outer ring;

a rigid inner ring; and

a deformable ring disposed between the rigid outer ring and the inner outer ring.

20. The heat exchanger unit of claim 17 , wherein an at least one of the plurality of coolers comprises a core welded with a tank, wherein the core further comprises a core end having a core end mass, wherein the tank further comprises a tank end having a tank end mass, and wherein the core end mass is greater than the respective tank end mass.
