Abstract

Embodiments of the disclosure pertain to a heat exchanger unit that includes a frame and at least one cooler. The cooler is associated with a respective side region of the heat exchanger unit, and the cooler has an outer surface and an inner surface. The unit can include a mount assembly for coupling the cooler to the frame. The mount assembly includes 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. The cooler may have a core end mass greater than a tank end mass.

First claim

a mount assembly for coupling 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 rigid inner ring, wherein the elongated fastening member extends through the rigid inner ring and at least partially into the frame.

2. The heat exchanger unit of claim 1 , further comprising:
a vertical axis;
an airflow region within the heat exchanger unit; and
a first set of baffles, each of the first set of baffles configured at a first angle to the vertical axis.

3. The heat exchanger unit of claim 2 , further comprising:
a second set of baffles, each of the second set of baffles configured at a second angle to the vertical axis; and
a third set of baffles, each of the third set of baffles configured at a third angle to the vertical axis.

4. The heat exchanger unit of claim 3 , wherein the first set of baffles, the second set of baffles, and the third set of baffles each comprise four baffles, 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, and wherein each of the first angle, second angle, and third angle is in a range of 30 to 60 degrees.

5. The heat exchanger unit of claim 1 , further comprising:
a fan mount bar extending between one of the plurality of side regions and another of the plurality of side regions; and
a fan mounted to the fan mount bar, the fan further comprising a motor and a plurality of fan blades in a range of 8 to 12.

6. The heat exchanger unit of claim 1 , wherein each of the plurality of coolers are configured to permit airflow to pass therethrough, and wherein operation of a fan results in airflow through each of the plurality of coolers, into an airflow region, and out of an exhaust outlet.

7. The heat exchanger unit of claim 1 , wherein a weld between the tank end and the core end is a v-groove weld.

8. A heat exchanger unit, comprising:
a vertical axis;
a frame comprising at least one side region;
at least one cooler coupled with the frame proximate to the respective side region, the at least one cooler comprising a tank end welded to a core end, wherein a tank end mass of the tank end is less than a core end mass of the core end; and
a mount assembly for coupling the at least one cooler 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 rigid inner ring,

wherein the elongated fastening member extends through the rigid inner ring and at least partially into the frame.

9. The heat exchanger unit of claim 8 , further comprising:
a first set of baffles, each of the first set of baffles configured at a first angle to the vertical axis, and at least one baffle of the first set of baffles comprises a sound absorbing material;
a second set of baffles, each of the second set of baffles configured at a second angle to the vertical axis; and
a third set of baffles, each of the third set of baffles configured at a third angle to the vertical axis
wherein each of the first angle, the second angle, and the third angle are in a range of 30to 60 degrees.

10. The heat exchanger unit of claim 9 , further comprising:
a tubular fan mount bar;
a shroud coupled to a top surface of the frame;
an aeroring; and
a fan mount coupled to the tubular fan mount bar; and
a fan coupled to the fan mount, the fan further comprising a hydraulic motor.

11. The heat exchanger unit of claim 10 , wherein the hydraulic motor is powered by a pressurized hydraulic fluid pressurized to a range of 2000 to 6000 psi, and wherein at least one of the first, second, or third set of baffles is positioned a quarter wavelength below the fan, the quarter wavelength being calculated based on a dominant acoustic frequency generated by the fan.

12. The heat exchanger unit of claim 8 , wherein a weld between the tank end and the core end is a v-groove weld, and wherein the mount assembly further comprises: a top plate, a bottom plate, and a washer.

13. A heat exchanger unit, comprising:
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, and each of the plurality of coolers comprising a core welded with a tank; and
an airflow region within the heat exchanger unit;
wherein each core further comprises a core end having a core end mass associated with a core end volume of material, wherein each tank further comprises a tank end having a tank end mass associated with a tank end volume of material, and wherein each core end mass is greater than each respective tank end mass.

14. The heat exchanger unit of claim 13 , further comprising:
a mount assembly for coupling at least one of the plurality of coolers to the frame, the mount assembly comprising:
