A cooling system includes a radial fan rotatable by an axis to deliver radial air flow to the cooling system, a plurality of heat exchangers spaced radially from the fan and arranged around the fan in a box-like configuration to receive the radial air flow therefrom, with the heat exchangers bounding an interior space of the cooling system. One of the heat exchangers is provided in the form of a charge air cooler that includes a first flow path for a charge air flow in heat exchange relation with a second flow path for an engine coolant flow of the vehicle. The cooling system further includes a surface associated with the charge air cooler to substantially block the radial air flow from exiting the interior space through the charge air cooler.

Box-like cooling system

An economically manufactured heat exchanger is provided and includes a plurality of elongated, straight, flat tubes (), each formed of two identical halves () joined to each other in mirror image fashion and each having opposed open ends and all arranged in a stack (). At least one spacer wall () is disposed within each tube and extends generally from end to end thereof to define at least two side-by-side first fluid flow paths within a tube. An elongated housing () contains the stack and includes spaced headers () with each header including a tube slot for the adjacent end of each tube () in the stack (). Spacers () in the stack separate adjacent tubes in the stack from one another and the spacers include ribs defining a serpentine flow path for a second fluid. An opening () is located in the housing () near each end thereof and is in fluid communication with the second fluid flow path ().

Heat exchanger

A heat exchanger including a first header having an inlet therein, a second header, an outlet in one of the first and second headers, and a plurality of flat tubes extending between the first and second headers for carrying a fluid between the first and second headers. A first connector is also provided for connecting a first exterior line to one of the first and second headers, the first connector being proximate and substantially parallel to an end of one of the flat tubes. In a compact cooling system, such heat exchangers may be disposed about a radial fan directing air flow outwardly away from the fan axis. One of a system inlet and a system outlet are connected via the first exterior lines to the first connectors of at least two of the heat exchangers.

Compact heat exchanger for a compact cooling system

An air-cooled charge air cooler for vehicles with a coolant-filled pre-cooler oriented in an air collection tank of the charge air cooler. The pre-cooler is sized to contact a majority of the charge air entering the charge air cooler. The pre-cooler has flow paths carrying coolant between manifolds of the pre-cooler and the flow paths define channels therethrough to direct charge air through the pre-cooler and into a cooling grate of the charge cooler. The channels have a depth that allows for a corresponding adjustment in the length of the cooling grate of the charge air cooler while maintaining the overall space requirement for the charge air cooler in a vehicle and meeting the increasing performance requirements for such charge air coolers.

Vehicle charge air cooler with a pre-cooler

A compact cooling system including a radial fan directing air flow outwardly and a plurality of heat exchangers disposed around the radial fan. Each heat exchanger has a plurality of tubes extending between an inlet header and an outlet header, with the headers extending generally in the same direction as the fan axis. A system inlet is connected to the inlet headers and a system outlet is connected to the outlet headers, whereby the length of the connection between each heat exchanger and the system outlet and system inlet is generally the same for each heat exchanger.

A transmission drives a radial fan about a fan axis in a vehicle cooling unit including a plurality of heat exchangers arranged to surround the radial fan to receive a radial air flow therefrom. A driving pulley, a driven pulley, and a idler pulley of the heat exchangers.

Transmission for driving a radial fan of a vehicle cooling unit

A compact cooling system for a vehicle includes an assembly of heat exchangers ( ), ( ), ( ) and ( ) connected to each other to provide a box-like configuration. Each heat exchanger ( ), ( ), ( ), ( ) includes a core with headers ( ), ( ) at each end in fluid communication with spaced, flattened tubes ( ) with fins (24) extending between the tubes in each of the cores. One of the cores ( ) is generally horizontal and located at the upper side of the box-like configuration. A radial discharge fan ( ) is located within the box-like configuration and receives cooling air and directs the same radially outwardly through the cores to cool fluid passing through the tubes ( ) of the cores. An equalization tank ( ), ( ) is mounted on the box-like configuration in overlying, spaced relation to a substantial portion of the surface of the heat exchanger ( ) so as to be in the path of cooling air merging from the heat exchanger ( ) to divert the same.

Equalization vessel for vehicular compact cooling systems

An exhaust gas heat exchange system for an internal combustion engine ( ) includes an intake manifold ( ) including an inlet ( ) for recirculating exhaust gases and an exhaust manifold ( ) having at least one inlet ( ) for receiving exhaust gas from the engine ( ) and an outlet ( ), ( ), for discharging exhaust gas and spaced from the inlets ( ). An exhaust gas heat exchanger ( ) includes a first flow path having an inlet ( ) connected to the exhaust manifold ( ) to receive exhaust gas therefrom, an outlet ( ) for discharging cooled exhaust therefrom and a second flow path in heat exchange relation with the first flow path for receipt of a coolant whereby exhaust gas flowing in the first flow path may be cooled. An exhaust valve ( ) has a first inlet ( ) connected to the first flow path of the heat exchanger ( ), a second inlet ( ) connected to the exhaust manifold ( ) and an outlet ( ) connected to the intake manifold ( ) together with a valve mechanism having at least one movable component ( ) movable between positions connecting the first inlet ( ) and the outlet ( ) and connecting the second inlet ( ) and the outlet ( ). An actuator ( ) is connected to the exhaust valve ( ) for operating the same.

Exhaust gas heat exchange system for an internal combustion engine

An exhaust gas heat exchanger including a stack of heat exchanger plates that form separate flow channels that run parallel to each other, collection spaces, and inlets and outlets for the exhaust gas and for the preferably liquid coolant. The flow channels for the one of the media formed from heat exchanger plates are longer than the flow channels for the other medium, and pass through the collection space for this other medium. The heat exchanger also includes a region without a housing in which the two flow channels run parallel to each other.
