[0033] Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways.DETAILED DESCRIPTION

[0034] Fig. 1 illustrates a cooling module 10 for use in a generator set (“genset”) 12 (Fig. 13). Referring to Fig. 13, in the illustrated embodiment, the genset 12 includes an engine 14 and an electrical generator 16. The engine 14 drives the electrical generator 16 to produced electrical power. The engine 14 can be any suitable engine for driving the electrical generator 16, including a diesel engine, an internal combustion engine, a natural gas engine, a hydrogen engine, a fuel cell, or the like. The genset 12 further includes a fan 18 that is powered by electricity produced by the electric generator 16 or by rotational output from the engine 14, either directly or indirectly, for example through a pulley system. The fan 18 generates a coolingAttorney Docket No. 022233-0057-W001 airflow that is used to cool a fluid in the cooling module 10. The cooling module 10 can include a charge air cooler for the engine 14, a radiator for engine coolant for the engine 14, oil coolers, fuel coolers, and radiators for a secondary cooling circuit, and the like. The cooling module 10 uses the cooling airflow generated by the fan 18 to cool a relatively warm fluid and direct the fluid back to the engine 14. The fluid can include engine coolant, combustion charge air, and the like. In the illustrated embodiment, the engine 14, the electrical generator 16, the fan 18, and the cooling module 10 are all mounted onto a skid 20 so that the genset 12 can be easily moved to different locations depending on where electrical power is needed. The skid 20, including the genset components 10, 18, 14, 16, can be moved by a forklift and the like. In some embodiments, the genset 12 has a capacity in a range from 500kW to 4,000kW. In other embodiments, the genset 12 has a capacity in a range from l,500kW to 2,500kW.

[0035] Referring to Fig. 1, the illustrated cooling module 10 includes a shroud 22, a first heat exchanger 24 mounted to the shroud 22 and a second heat exchanger 26 mounted to the shroud 22. In the illustrated embodiment, the shroud 22 is a structural shroud that provides a support structure for the heat exchangers 24, 26. In one embodiment, the first heat exchanger 24 is a radiator used for cooling engine coolant and the second heat exchanger 26 is a charge air cooler for cooling combustion air. In another embodiment, the cooling module is a low-temperature radiator system that does not include a charge air cooler and both the first and second heat exchangers 24, 26 are radiators used for cooling engine coolant. Also, while not illustrated in some embodiments, the cooling module may include additional heat exchangers. For example, in some embodiments, additional heat exchangers can be mounted to the illustrated heat exchangers 24, 26 in front of the heat exchangers 24, 26 so that the airflow travels through the additional heat exchangers before traveling through either of the heat exchangers 24 or 26.

[0036] Referring to Figs. 1 and 2, the structural shroud 22 includes a first sidewall 28 and a second sidewall 30 that is opposite the first sidewall 30. A third sidewall 32 extends from the first sidewall 28 to the second sidewall 30 and a fourth sidewall 34 is opposite the third sidewall 32 and extends from the first sidewall 28 to the second sidewall 30. In the illustrated embodiment, the sidewalls 28, 30, 32, and 34 are generally straight (i.e., not curved) such that the structural shroud 22 is generally in the shape of square or rectangle. Also, in the illustrated embodiment, the first and second sidewalls 28, 30 are horizontal sidewalls where the firstAttorney Docket No. 022233-0057-W001 sidewall 28 forms a top wall and the second sidewall 30 forms a bottom wall that is adjacent the skid 20. The illustrated third and fourth sidewalls 32, 34 form vertical walls that extend from the bottom to the top walls. The sidewalls 28, 30, 32, 34 define a plenum 36 (Fig. 3) that directs the cooling airflow from the fan 18 toward the first and second heat exchangers 24, 26.

[0037] Referring to Figs. 2 and 3, the structural shroud 22 includes a first end 38 and a second end 40 and the cooling airflow flows through the plenum 36 from the first end 38 and through the second end 40. The structural shroud 22 includes a shroud panel 42 adjacent the first end 38. The illustrated shroud panel 42 includes a circular aperture 44 through which the cooling airflow enters the plenum 36 from the fan 18. In one embodiment, the fan 18 is coupled to the structural shroud 22 adjacent the shroud panel 42. And, in some embodiments, the fan 18 is located inside the circular aperture 44 of the shroud panel 42.

[0038] Referring to Fig. 6, the plenum 36 has a height 46 measured from the first sidewall 28 to the second sidewall 30 and a width 48 measured from the third sidewall 32 to the fourth sidewall 34. As will be discussed below, the third and fourth sidewalls 32, 34 have a length 50 that is adjustable to change the height 46 of the plenum 36 to accommodate heat exchangers with different heights or tube lengths. In some embodiments, the length 50 is in a range from 2 meters to 3 meters and in other embodiments in a range from 1.5 meters and 2 meters. The third and fourth sidewalls 32, 34 each include a first panel 52, a second panel 54, and a third panel 56. The first panel 52 is coupled to and adjacent the first sidewall 28. The second panel 54 is coupled to and adjacent the second sidewall 30. The third panel 56 extends from the first panel 52 to the second panel 54. The third panel 56 has a length 58. As shown in Figs. 6 - 9, the first and second panels 52, 54 can be connected to the third panel 56 at different positions along the length 58 of the third panel 56 to adjust the height 46 of the plenum 36. For example, as shown in Fig. 7, the first and second panels 52, 54 can be connected to the third panel 56 at a first position such that there is a first distance 60 separating the panels 52, 54. The length 58 of the third panel 56 is greater than the distance 60 such that the third panel 56 overlaps onto the first and second panels 52, 54. As shown in Fig. 8, the first and second panels 52, 54 can be connected to the third panel 56 at a second position such that there is no distance separating the panels 52, 54. The configuration shown in Fig. 8 would set the structural shroud 22 to a minimum height 46 of the plenum 36. As shown in Fig. 9, the first and second panels 52, 54 canAttorney Docket No. 022233-0057-W001 be connected to the third panel 56 at a third position such that there is a second distance 62 separating the panels 52, 54. The second distance 62 is greater than the first distance 60 (Fig. 7). Also, the length 58 of the third panel 56 is greater than the distance 62 such that the third panel 56 overlaps onto the first and second panels 52, 54 in Fig. 9. With the second distance 62 being greater than the first distance 60, the height 46 of the plenum 36 is greater in the configuration shown in Fig. 9 then in the configurations shown in Figs. 7 and 8. Thus, in the configuration shown in Fig. 9, the structural shroud 22 can accommodate a heat exchanger having a height 64 (Fig. 1) greater than the configurations shown in either Figs. 7 or 8. In the illustrated embodiment, the third panel 56 is shown and described as having a fixed length 58. In other embodiments, the third panel 56 may vary in length to adjust the length 50. In such embodiments, where the third panel 56 varies in length, the third panel may connect to the first and second panels 52, 54 at the ends of the panels 52, 54 and not overlap the panels 52, 54.

[0039] Referring to Figs. 1 and 2, the heat exchangers 24, 26 include similar components and only one of the heat exchangers 24 will be described in detail and like components have been given the same reference number. The heat exchanger 24 includes an inlet tank 66, an outlet tank 68, and a heat exchanger core 70 between the inlet and outlet tanks 66, 68. The inlet tank 66 includes a fluid inlet 72 that receives a relatively warm fluid (e.g., charge air, engine coolant, etc.) from a component of the genset 12. The component may include the engine 14, the generator 16, a turbocharger, etc. The outlet tank 68 include a fluid outlet 74 that directs the fluid back toward the component of the genet 12 after the fluid is cooled by the cooling airflow that passes over the heat exchanger core 70.

[0040] The heat exchanger core 70 includes a plurality of heat exchanger tubes 76 arranged in a parallel flow arrangement. Each of the heat exchanger tubes 76 extends from the inlet tank 66 to the outlet tank 68 to transport the fluid from the inlet tank 66 to the outlet tank 68 while transferring heat from the fluid to the cooling airflow that travels through the plenum 36, which was generated by the fan 18. In some embodiments, fins 87 are located between adjacent tubes. The fins 87 direct airflow between the tubes and enhance heat transfer between the airflow and the fluid in the tubes. Any suitable fin construction can be utilized, including louvered fins. In one embodiment, the tubes 76 have a length 78 in a range from 1,500mm to 2,000mm. In another embodiment, the tubes 76 have a length 78 greater than 1,750mm. In yet otherAttorney Docket No. 022233-0057-W001 embodiments, the tubes 76 have a length 78 in a range from 1,000mm to 1,500mm. In yet other embodiments, the tube 76 have a length 78 in a range from 1,000mm to 4,000mm. The heat exchanger core 70 has a width 81. In one embodiment, the width 81 is in a range from 500 mm to 2,000 mm. In other embodiments, the width 81 is in a range from 1,000 mm to 2,000 mm.

[0041] With reference to Fig. 1, in the illustrated embodiment the tubes 76 extend in a direction from the top sidewall 28 to the bottom sidewall 30 and thus the tanks 72, 74 are adjacent either the top sidewall 28 or the bottom sidewall 30. However, in other embodiments, the tanks 72, 74 can be arranged such that the tubes 76 extend in a direction from the sidewall 32 to the sidewall 34 that are generally vertical.

[0042] Fig. 5 illustrates a portion of one possible heat exchanger tube 76 for use in the heat exchangers 24, 26. The illustrated tube 76 is a folded tube that is formed by folding a sheet of material, an aluminum sheet of material in one embodiment. The illustrated folded tube 76 includes no welded seem. Rather, the aluminum sheet is folded to form the tube 76 and the tube 76 is brazed to seal the folded joints and seams. In other embodiments, the tube 76 includes a weld seam and is a welded tube.

[0043] Referring to Figs. 1 - 4, the inlet tank 66 is fastened to the first sidewall 28 of the structural shroud 22 adjacent the second end 40 of the structural shroud 22. The inlet tank 66 is fastened to the first sidewall 28 so that the inlet tank 66 is outside of the plenum 36 such that the sidewalls 28, 30, 32, 34 do not surround the inlet tank 66. The inlet tank 66 includes a fastener aperture 80 (Fig. 4) that receives a fastener (e.g., bolt, screw, pin, etc.) that removably secures the inlet tank 66, and heat exchangers 24, 26, to the first sidewall 28. The first sidewall 28 includes a flange 82 that receives the fastener to secure the inlet tank 66 to the first sidewall 28. In the illustrated embodiment, the flange 82 is bent or extends outwardly, but in other embodiments, the flange 82 may be bent or extend inwardly. Similarly, the outlet tank 66 is fastened to the second sidewall 30 of the structural shroud 22 adjacent the second end 40 of the structural shroud 22. The outlet tank 68 is fastened to the second sidewall 30 so that the outlet tank 68 is outside of the plenum 36 such that the sidewalls 28, 30, 32, 34 do not surround the outlet tank 68. The outlet tank 68 includes a fastener aperture 84 (Fig. 2) that receives a fastener (e g., bolt, screw, pin etc.) that removably secures the outlet tank 68, and heat exchangers 24, 26,Attorney Docket No. 022233-0057-W001 to the second sidewall 30. The second sidewall 30 includes a flange 86 that receives the fastener to secure the outlet tank 68 to the second sidewall 30.

[0044] Fig. 22 illustrates a tank 65 that can be used in place of the inlet tank 66 or the outlet tank 68. The tank 65 includes apertures 80 that form a first mounting location 80a, a second mounting location 80b, a third mounting location 80c, and a fourth mounting location 80b for connecting the tank 65 and therefore heat exchanger 24, 26 to the shroud 22. The illustrated tank 65 includes four mounting locations 80a, 80b, 80c, and 80d but in other embodiments the tank 65 includes three mounting locations. As discussed above, the apertures 80 can be used with a fastener (e.g., bolt, screw, pin) to connect the tank 65 to the shroud 22. The fastener can be used in combination with an isolator, such as a rubber isolator, for minimizing vibrations that are transferred from the shroud 22 to the heat exchangers 24, 26. The tank 65 can be formed from any suitable material including plastic, cast aluminum, and the like. It has been found that the mounting configuration shown and described in regard to Fig. 22 reduces stresses and displacement on the tubes 76, which reduces tube 76 to tank 65 joint failures.

[0045] The heat exchanger core 70 is fastened to the structural shroud 22 by way of the inlet and outlet tanks 66, 68 being fastened to the structural shroud 22 as discussed above. Thus, the entire heat exchanger, including the core 70, can easily be removed from the shroud 22 by disconnecting the fasteners that hold the tanks 66, 68 to the respective sidewall 28, 30. Also, the heat exchanger core 70 is located outside of the plenum 36. For example, the heat exchanger core 70 is located beyond the second end 40 of the structural shroud 22 in the direction of the cooling airflow (direction of arrow 88 in Fig. 1). Also, the sidewalls 28, 30, 32, 34 do not surround the heat exchanger core 70. The structural shroud 22 provides the structure and support for the heat exchangers 24, 26 on the skid 20 and the shroud 22 also forms the plenum 36 for cooling airflow.

[0046] Also, in the illustrated embodiments, the length 78 of the heat exchanger tubes 76 extend substantially the entire length 50 of the third and fourth sidewalls 32, 34 as shown in Fig. 1. That is, the length 78 of the tubes 76 is approximately equal to the height 46 (Fig. 6) of the plenum 36 and the tubes 76 extend from about the top wall 28 to the bottom wall 30 of the shroud 22. Therefore, only one heat exchanger 24 (or heat exchanger 26) is needed to span theAttorney Docket No. 022233-0057-W001 entire height of the structural shroud 22. Such a configuration maximizes the heat exchange efficiently while minimizing the amount of material needed to form the cooling module 10.
