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 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.

摘要： 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.

摘要： A housingless heat exchanger including a stack of flat tubes with at least two being cooling tubes and at least one being a bypass tube. Collecting tanks are on the tube ends and diffuse gas streaming in the tube flow paths. The flat tubes each comprise a connected pair of plates defining a flow path, and an enclosed space is defined between adjacent flat tubes. Coolant inlet and outlet channels are formed by connected plate openings connect to the enclosed space between the cooling tubes whereby coolant flows through that enclosed space. A switching valve in one collecting tank is movable between a cooling position in which the gas streams through the cooling tubes and a bypass position in which the gas streams through the bypass tube. A closure in the coolant inlet and outlet channels blocks coolant from adjacent the bypass tube. An insulating plate may also, or alternatively, be between the bypass tube and the cooling tube adjacent the bypass tube to block heat exchange between coolant and the bypass tube.

摘要： A frame supports heat exchangers one in front of another in the direction of flow of cooling air, and includes two vertical walls interconnected by transverse walls, cross braces between the walls, and fastening points on the walls adapted to fasten the heat exchangers to the frame. Outwardly extending bulging sections in the vertical walls include an outer portion adapted to be secured to the vehicle support members to support the frame thereon, and an inner portion defining a space between vertical wall sections above and below the bulging section for receive projecting components of at least one heat exchanger. Connectors connect each of the fastening openings to the aligned flange openings, with the connectors including a head and a stem with an expandable end opposite the head retaining the connectors in the aligned openings. Hooks support the heat exchangers in the direction of air flow, with the connector stems supporting against at least some forces transverse to the direction of air flow.
