FRAMELESS COOLING MODULE

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Patent Application No. 63/657,467, filed June 7, 2024, the entire content of which is hereby incorporated by reference.

BACKGROUND

[0002] Cooling modules used in relatively large combustion engines, such as diesel engines for on-road and off-road applications, typically use a heat exchanger, e.g., a radiator, and a charge air cooler to cool fluids circulating through the engine components. The heat exchanger receives high temperature coolant from the engine and outputs low temperature coolant to circulate back through the engine. Combustion engines include a combustion chamber to create power. To maximize the power output of the engine, compressed air is forced into the combustion chamber. For this reason, engines such as diesel engines often include a turbocharger or supercharger to compress the air before the air enters the combustion chamber. During compression of the air in the turbocharger or supercharger, the compressed air is heated to a temperature that may negatively affect the efficiency of the combustion process. The use of cooler air in the combustion process increases the engine efficiency and power output. To address this, relatively warmer, compressed air leaving the turbocharger or supercharger is passed through the charge air cooler to lower the temperature of the compressed air. The relatively cooler compressed air leaving the charge air cooler is then routed to the engine for use in the combustion process.

SUMMARY

[0003] The present disclosure provides, in one aspect, a frameless cooling module to cool a fluid in a motorized vehicle. The frameless cooling module includes a first heat exchanger, e.g., a charge air cooler. The charge air cooler includes an inlet manifold, an outlet manifold, and a plurality of cooling ducts fluidly connecting the inlet manifold to the outlet manifold. The cooling ducts are thermally coupled to a plurality of fins. The fins are configured to dissipate heat from the fluid passing from the inlet manifold to the outlet manifold. The inlet manifold and the outlet manifold are configured to directly couple to a chassis of the motorized vehicle. [0004] In some embodiments, the frameless cooling module includes a second heat exchanger to dissipate heat from a coolant. The heat exchanger may include a separate plurality of cooling ducts through which the coolant passes through. Air passing over the cooling ducts dissipates heat from the coolant. The heat exchanger may be coupled to the first heat exchanger, such that the second heat exchanger is supported via the first heat exchanger by the chassis of the motorized vehicle.

[0005] Other features and aspects of the invention will become apparent by consideration of the following detailed description and accompanying drawings.

DETAILED DESCRIPTION

[0021] FIGS. 1 and 2 illustrate a frameless cooling module 100 to be implemented into an engine in a motorized vehicle, such as a truck having a diesel engine. The frameless cooling module 100 cools a fluid passing through the frameless cooling module 100 to a lower temperature. As shown in FIGS. 1 and 2, the frameless cooling module 100 includes a first heat exchanger, e.g., a charge air cooler, 108. The first heat exchanger 108 is generally obscured in Fig. 1 by a second heat exchanger, e.g., a radiator, 110, although components connected to the first heat exchanger 108 extend beyond the second heat exchanger 110 and are thus visible. The second heat exchanger 110 is connected to and is supported by the first heat exchanger 108. In other examples, the frameless cooling module 100 may include any type or any number of heat exchangers.

[0022] In some embodiments, the frameless cooling module 100 includes a fan to draw air over the second heat exchanger 110 and then the first heat exchanger 108 such that air passes over respective cooling ducts thereon. The first heat exchanger 108 and the second heat exchanger 110 are positioned relative to each other such that the fan can draw air through the first the first heat exchanger 108 and then through the second heat exchanger 110 before the air passes through a fan housing 112 where the fan is positioned. The fan has been omitted for clarity of illustration. In some embodiments of the frameless cooling module 100, the fan may be omitted from the assembly and separately attached to the vehicle. In the embodiment illustrated in Figs. 1 and 7, the fan housing 112 is provided as part of the frameless cooling module 100. The fan is mounted within the fan housing 112, which provides a duct for the fan to draw air through. More specifically, the fan housing 112 includes an opening 114 where the fan may be positioned, such that the fan draws air across the second heat exchanger 110 and first heat exchanger 108 and through the opening 114. The fan housing 112 is coupled to the second heat exchanger 110, which is described in further detail below.

[0023] With reference to FIG. 3, the second heat exchanger 110 extends from a top end 116 to a bottom end 120 opposite from the top end 116. An inlet manifold 124 is positioned at the top end 116 and an outlet manifold 128 is positioned at the bottom end 120. The inlet manifold 124 is fluidly connected to the outlet manifold 128 by a plurality of cooling ducts 132. The plurality of cooling ducts 132 may include a conductive material suitable for high heat transfer (e.g., aluminum, copper, etc.). The cooling ducts 132 run in a first direction 119 from the top end 116 to the bottom end 120. Between each of the plurality of cooling ducts 132 is a plurality of heat dissipating fins 136 that are thermally coupled to adjacent cooling ducts of the plurality of cooling ducts 132. The fins 136 are a heat sink to absorb heat from the fluid passing through the plurality of cooling ducts 132. In some embodiments, the fins 136 include the same material as the plurality of cooling ducts 132. In other embodiments, the fins 136 and the plurality of cooling ducts 132 are different materials.

[0024] The inlet manifold 124 includes an inlet port 140 to receive the fluid. In the illustrated embodiment, the fluid passing through the second heat exchanger 110 is a coolant circulated through the engine to absorb heat from components of the engine. A relief port 144 extends from the inlet manifold 124. The relief port 144 may allow pressure or fluidic relief to the coolant within the second heat exchanger 110 if a coolant temperature or volume exceeds a threshold value. The inlet manifold 124 further includes a first plurality of fastener bores 148 that, together with fasteners, serve to couple the fan housing 112 to the second heat exchanger 110. A first plurality of fastener receptacles 152 (see FIG. 1) are also positioned on the inlet manifold 124. The first plurality of fastener receptacles 152, with the fasteners, serve to couple the second heat exchanger 110 to the first heat exchanger 108.

[0025] The outlet manifold 128 includes an outlet port 156 to allow the fluid to exit the second heat exchanger 110 and return to the engine via piping (not shown). In the embodiment illustrated in FIG. 2, the outlet manifold 128 further includes a valve 160 having a valve outlet 164. In other embodiments, the valve 160 and the valve outlet 164 is omitted. The valve 160 is operable by a user to drain fluid remaining in the second heat exchanger 110. The outlet manifold 128 includes a second plurality of fastener bores 168. The first plurality of fastener bores 148 and the second plurality of fastener bores 168 receive a fastener 172 (see FIG. 1). The fastener 172 couples the fan housing 112 to the inlet manifold 124 and to the outlet manifold 128.

[0026] With reference to FIG. 4, the first heat exchanger 108 includes an inlet manifold 180 extending from a first end 184 to a second end 188 opposite the first end 184. An inlet port 192 is positioned in the inlet manifold 180 at the first end 184. The inlet port 192 receives compressed air from a turbocharger (not shown). The compressed air from the turbocharger or supercharger used to compress the air prior to entering the inlet port 192 has a relatively high temperature. The compressed air is forced through a plurality of cooling ducts 196 to dissipate heat from the compressed air into air passing over the first heat exchanger 108. The cooling ducts 196 extend in a second direction 195 generally perpendicular to the first direction 119. The cooling ducts 196 are spaced apart by a plurality of heat dissipating fins 200, similar to the plurality of heat dissipating fins 136. The fins 200 absorb heat from the compressed air passing through the cooling ducts 196 so that it can be passed to the ambient air passing over the fins 200.

[0027] The first heat exchanger 108 includes an outlet manifold 204 extending from a first end 208 to a second end 212 opposite the first end 208. An outlet port 216 is positioned at the first end 208 and is in fluid communication with a combustion chamber of the engine via piping (not shown). The compressed air leaving the first heat exchanger 108 and entering the combustion chamber is at a relatively lower temperature compared to the air entering the inlet port 192. [0028] With continued reference to FIG. 4, the first end 184 of the inlet manifold 180 and the first end 208 of the outlet manifold 204 each include a first fastening slot 220. The first fastening slot 220 receives a fastener 224 (see FIG. 1). Respective fasteners 224 are each received into one of the first plurality of fastener receptacles 152 on the inlet manifold 124 of the second heat exchanger 110. The second end 188 of the inlet manifold 180 and the second end 212 of the outlet manifold 204 each include a second fastening slot 230 configured to receive one of a plurality of pins 176 extending from the outlet manifold 128 of the second heat exchanger 110. The second heat exchanger 110 and the fan are coupled to the first heat exchanger 108 via the plurality of pins 176.

[0029] The inlet manifold 180 connects to a first mounting bracket 232 and the outlet manifold 204 connects to a second mounting bracket 236. The first and second brackets 232, 236 are fastened to respective manifolds 180, 204. In other examples, the brackets 232, 236 are integral with the manifolds 180, 204. The mounting brackets 232, 236 may be directly coupled to a chassis 240 of the vehicle. In some examples, the as result of the connection between the mounting brackets 232, 236 to the chassis 240, the first heat exchanger 108 and the second heat exchanger 110 are suspended between the mounting brackets 232, 236. In other embodiments, the mounting brackets 232, 236 may be coupled to another component of the vehicle. In some embodiments, a bushing (e.g., a rubber bushing) is positioned between the chassis 240 and the mounting brackets 232, 236 to limit vibrations from the chassis 240 passing into the mounting brackets 232, 236, and thus into the frameless cooling module 100. The use of mounting brackets 232, 236 directly coupled to the first heat exchanger 108 and the chassis 240 of the vehicle is advantageous due to the lack of need for an additional frame to support the first heat exchanger 108. Stated otherwise, the inlet manifold 180 and the outlet manifold 204 are robust enough to support substantially the entire mass of the frameless cooling module 100 during operation of the vehicle. Other, non-structural components may also ultimately connect to the vehicle from the first heat exchanger 108 and the second heat exchanger 110 such as hoses, guards, wiring, etc., but these other components will not bear the load of the frameless cooling module 100. Adding an additional frame increases the weight and cost of the cooling module and occupies space in the engine compartment that could be used for other components. Thus, the frameless cooling module 100 described herein provides several specific advantages over other cooling modules that require separate, load bearing component.

[0030] With reference to FIG. 5, the frameless cooling module 100 includes a plurality of isolators that absorb dimensional changes due to thermal expansion of the second heat exchanger 110 and the first heat exchanger 108 relative to one another during operation. In some embodiments, the isolators are rubber, which is resilient enough to absorb the dimensional changes due to the thermal expansion. Each of a first plurality of isolators 244 is positioned between one the first plurality of fastener receptacles 152 and a respective one of the first fastening slots 220. Each of the first isolators 244 extends annularly around one of the fasteners 224 that couples the inlet manifold 180 and the outlet manifold 204 of the first heat exchanger 108 to the inlet manifold 124 of the second heat exchanger 110. With reference to FIG. 6, each of a second plurality of isolators 248 are positioned between one of the pins 176 and one of the second fastening slots 230. Each of the second plurality of isolators 248 extends annularly around a respective one of the pins 176.

The frameless cooling module 300 includes a first heat exchanger 308 that supports a second heat exchanger 310. The second heat exchanger 310 includes an inlet manifold 312 and an outlet manifold 316. The inlet manifold 312 is fluidly connected to the outlet manifold 316 by a plurality of cooling ducts that are similar to the plurality of cooling ducts 132.

The outlet manifold 324 includes an outlet port 340 and forms a funnel or V-shape. The outlet manifold 324 includes a second plurality of mounting brackets 344 extending from and integral with the outlet manifold 324. The inlet manifold 320 is fluidly connected to the outlet manifold by a plurality of cooling ducts extending in the first direction 119 (e.g., the same direction as cooling ducts of the second heat exchanger 310 relative to the other structure of the frameless cooling module 300). [0033] The first plurality of mounting brackets 334 and the second plurality of mounting brackets 344 are directly coupled to a chassis (not shown in FIGs. 7 and 8) of a vehicle.

The protrusions 428 form a honey-comb pattern, which provides additional structural support to the frameless cooling module 400.

[0036] The inlet manifold 420 of the first heat exchanger 408 includes a first arm 432 extending to the inlet manifold 412 of the second heat exchanger 410. The inlet manifold 420 of the first heat exchanger 408 also includes a second arm 434 extending to the outlet manifold 416 of the second heat exchanger 410.
