Abstract

Embodiments of the disclosure pertain to an improved heat exchanger unit that includes a frame having a top region, a bottom region, and a plurality of side regions. The unit has a first cooler coupled with the frame proximate to a respective side region and generally parallel to a vertical axis. The unit has a second cooler coupled with the frame proximate to the top region and generally perpendicular to the vertical axis. The unit includes an inner airflow region within the heat exchanger unit, and a first baffle disposed within the inner airflow region.

Claims (64)

1. A heat exchanger unit, comprising:

a vertical axis;

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

a first cooler coupled with the frame proximate to a respective side region and generally parallel to the vertical axis;

a second cooler coupled with the frame proximate to the top region and generally perpendicular to the vertical axis;

an inner airflow region within the heat exchanger unit; and

a first baffle disposed within the inner airflow region, and at a first angle to the vertical axis.

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

a third cooler coupled with the frame proximate to the respective side region, and adjacent the first cooler; and

a fourth cooler coupled with the frame proximate to the top region of the frame, and adjacent the second cooler.

3. The heat exchanger unit of claim 2 , further comprising a second airflow region partitioned from the inner airflow region, wherein the second airflow region is associated with the third cooler and the fourth cooler, and wherein a second baffle is disposed within the second airflow region, and at a second angle to the vertical axis.

4. The heat exchanger unit of claim 3 , wherein the first baffle and the second baffle comprise a sound absorbing material.

5. The heat exchanger unit of claim 4 , further comprising a fan configured to operate and produce a point source dominant acoustic frequency, and wherein the sound absorbing material is capable to reduce the point source dominant acoustic frequency by at least 10 dB.

6. The heat exchanger unit of claim 5 , wherein the sound absorbing material comprises mineral wool, and wherein each of the first angle and the second angle is in a range of about 30 to about 60 degrees.

7. The heat exchanger unit of claim 3 , further comprising: a first fan mounted to the frame external to a first side of the first cooler; and

a second fan mounted to the frame external to a first side of the second cooler,

the first fan and the second fan each comprising an axis of rotation substantially perpendicular to the vertical axis.

8. The heat exchanger unit of claim 1 , wherein the frame further comprises:

a first sidewall;

a second sidewall;

a back wall; and

a bottom.

9. The heat exchanger unit of claim 1 , wherein at least one of a first sidewall, a second sidewall, a back wall, and a bottom further comprises: an inner layer of sound absorbing material; and an exterior layer of a vinyl-based material.

10. A blender skid for creating a frac fluid mixture, the comprising:

a blender;

a first diesel engine;

a heat exchanger unit configured to cool at least one service fluid transferable between the heat exchanger unit and the first diesel engine, the heat exchanger unit further comprising:

a vertical axis;

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

a first cooler coupled with the frame proximate to a respective side region and generally parallel to the vertical axis;

a second cooler coupled with the frame generally perpendicular to the orientation of the first cooler;

an inner airflow region within the heat exchanger unit; and

a first baffle disposed within the inner airflow region, and at a first angle to the vertical axis.

11. The blender skid of claim 10 , wherein the second cooler is coupled proximate to the top region.

12. The blender skid of claim 10 , wherein the second cooler is coupled proximate to one of the plurality of side regions.

13. The blender skid of claim 10 , wherein the heat exchanger unit further comprises a second baffle disposed therein at a second angle to the vertical axis, wherein the first angle and the second angle are in a range of 30 degrees to 60 degrees, and wherein the first baffle and the second baffle comprise a sound absorbing material.

14. The blender skid of claim 10 , wherein the frame further comprises:

a first sidewall;

a second sidewall;

a back wall; and

a bottom,

wherein at least one of the first sidewall, the second sidewall, the back wall, and the bottom further comprises: an inner layer of sound absorbing material;

and an exterior layer of a vinyl-based material.

15. A heat exchanger unit, comprising:

a vertical axis;

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

a first cooler coupled with the frame proximate to a respective side region and generally parallel to the vertical axis;

a second cooler coupled with the frame proximate to the top region and generally perpendicular to the vertical axis;

a first fan mounted to the frame external to a first side of the first cooler;

an inner airflow region within the heat exchanger unit; and

a first baffle disposed within the inner airflow region, and at a first angle to the vertical axis.

16. The heat exchanger unit of claim 15 , further comprising:

a third cooler coupled with the frame proximate to the respective side region, and adjacent the first cooler; and

a fourth cooler coupled with the frame proximate to the top region of the frame, and adjacent the second cooler.

17. The heat exchanger unit of claim 16 , further comprising a second airflow region partitioned from the inner airflow region, wherein the second airflow region is associated with the third cooler and the fourth cooler, and wherein a second baffle is disposed within the second airflow region, and at a second angle to the vertical axis.

18. The heat exchanger unit of claim 17 , wherein the first baffle and the second baffle comprise a sound absorbing material.

19. The heat exchanger unit of claim 18 , wherein the sound absorbing material comprises mineral wool, and wherein each of the first angle and the second angle is in a range of about 30 to about 60 degrees.

20. The heat exchanger unit of claim 15 , wherein the frame further comprises:

a first sidewall;

a second sidewall;

a back wall; and

a bottom,

wherein at least one of the first sidewall, the second sidewall, the back wall, and the bottom further comprises: an inner layer of sound absorbing material;

and an exterior layer of a vinyl-based material.
