    摘要： 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.

    摘要： A compact cooling system for a vehicle includes an assembly of heat exchangers (10), (12), (14) and (16) connected to each other to provide a box-like configuration. Each heat exchanger (10), (12), (14), (16) includes a core with headers (20), (22) at each end in fluid communication with spaced, flattened tubes (18) with fins (24) extending between the tubes in each of the cores. One of the cores (10) is generally horizontal and located at the upper side of the box-like configuration. A radial discharge fan (42) 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 (18) of the cores. An equalization tank (60), (80) is mounted on the box-like configuration in overlying, spaced relation to a substantial portion of the surface of the heat exchanger (18) so as to be in the path of cooling air merging from the heat exchanger (10) to divert the same.

    摘要： An economically manufactured heat exchanger is provided and includes a plurality of elongated, straight, flat tubes (16), each formed of two identical halves (78,80) joined to each other in mirror image fashion and each having opposed open ends and all arranged in a stack (18). At least one spacer wall (36) 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 (10) contains the stack and includes spaced headers (20,22) with each header including a tube slot for the adjacent end of each tube (16) in the stack (18). Spacers (26) 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 (30) is located in the housing (10) near each end thereof and is in fluid communication with the second fluid flow path (28).

    摘要： The invention relates to an exhaust gas heat exchanger in an exhaust gas recirculation arrangement. The heat exchanger includes a plate stack which is surrounded by a housing. The plate stack can include two plates which are connected at their longitudinal edges to form a flat tube which contains a turbulator through which exhaust gas flows. The heat exchanger can also include a coolant duct which is equipped with flow directing elements arranged between two flat tubes. In order to make the exhaust gas heat exchanger more resistant to changing temperature stresses, the invention provides that the flow directing elements can be formed from a corrugated plate in which ducts with inlets and outlets are formed. At least some of the ducts in the inlet area of the coolant have a nonlinear profile so that changes in length are permitted between the plate stack and the housing.

    摘要： An exhaust gas heat exchange system for an internal combustion engine (10) includes an intake manifold (12) including an inlet (16) for recirculating exhaust gases and an exhaust manifold (28) having at least one inlet (30) for receiving exhaust gas from the engine (10) and an outlet (36), (60), for discharging exhaust gas and spaced from the inlets (30). An exhaust gas heat exchanger (32) includes a first flow path having an inlet (50) connected to the exhaust manifold (32) to receive exhaust gas therefrom, an outlet (52) 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 (32) has a first inlet (44) connected to the first flow path of the heat exchanger (32), a second inlet (47) connected to the exhaust manifold (28) and an outlet (48) connected to the intake manifold (12) together with a valve mechanism having at least one movable component (56) movable between positions connecting the first inlet (44) and the outlet (48) and connecting the second inlet (47) and the outlet (48). An actuator (76) is connected to the exhaust valve (32) for operating the same.

    摘要： 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.
