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

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.

Compact cooling system with similar flow paths for multiple heat exchangers

A cooler for an electrical component, including a pressure-tight vessel enclosing the electrical component and including a support plate above the electrical component, a bath of electrically insulating and evaporating liquid surrounding the electrical component within the vessel, a flow channel for cooling liquid on the support plate, and a heat exchange element. The heat exchange element includes a serpentine plate having generally horizontally extending and aligned flanks alternately connected along horizontally extending upper and lower edges, with the lower edges being connected by connectors spaced along the horizontally extending edges and the upper edges being connected by horizontally extending crests secured to the flow channel for heat conduction therebetween. The flow channel may define a U-shaped path with two channel legs connected at one end, with a cooling liquid inlet connected to one of the channel legs and a cooling liquid outlet connected to the other of the channel legs. The connectors connecting the lower edges of the flanks are defined between cutouts extending minimally into the flanks, and no more than &frac14; of the height of the flanks. The flanks define surfaces sloped no more than about 20&deg; from vertical.

Cooler for power electronics

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.
