A soldered cooler block, especially for a charge air cooler/coolant cooler, is constructed in a packet-type manner. Cooling channels for a liquid coolant are arranged in the cooler block in a crossways manner in first layers, and gas channels for a gas which is to be cooled are arranged in a crossways manner in second layers. The cooling channels are respectively formed by two wall areas which are arranged at a distance and by intermediate strips and connection strips that include groove profiles.

Cooler block, especially for a change air cooler/coolant cooler

A charge air cooler for internal-combustion engines, having at least two cooling circulations which are guided through heat exchanger blocks which are connected behind one another in the flow direction of the air and have different coolant temperatures. At least the heat transfer block provided as the first heat transfer block in the flow direction of the air is produced of a more erosion-resistant and temperature-stable material than the heat transfer block which fallow and is situated in la high-temperature coolant circuit in which the coolant temperature is selected to be as high as possible.

Charge air cooler and method of making and operating same

A plate-type heat exchanger for oil/coolant coolers on heat exchange media, as a rule, flow non-uniformly through known plate-type heat exchanger whose hollow chambers are provided with metal turbulence inserts because of the arrangement of these turbulence inserts. For increasing the heat exchange capacity, it is provided to divide the turbulence insert into sections in which a different alignment of rolled metal turbulence sheets takes place in each case. The sections are divided with respect to one another by separating cuts and, because of the different arrangement of their corrugations, have different flow resistances in sections for the flowing-through medium. As a result of this further development, it is possible to achieve a uniform flow in the hollow chambers.

Plate-type heat exchanger and method of making same

A fin-tube block and method of making a fin tube block for heat exchangers is disclosed. Tubes provided for the through-flow of the coolant are manufactured as adjacent channels in an extruded section with a plate shape and then stacked on one another, alternating with corrugated ribs and additional extruded sections in a packet assembly and then soldered.

Fin tube block for a heat exchanger and method of making same

Finned-tube blocks of charge air coolers of stacked construction are provided with end strips forming a tube bottom. Side surfaces of the end strips adjoining the coolant ducts are configured as exterior surfaces of lips projecting in a direction of the corrugated fins, the tips of these lips not touching the corrugated fins. The end strip cross-section, however, uniformly increases toward the side facing away from the corrugated fins. This further development leads to a considerable reduction of thermal induced tension peaks and therefore contributes to lengthening the useful life of charge air coolers provided with such finned-tube blocks.

Heat transfer device and method of making same

A fin-tube block for a heat exchanger and method of making same are disclosed. The thermal stress on fin-tube blocks of charge air coolers is considerable in the vicinity of the side parts, which can be attributed among other things to the rapid heating of the fin-shaped corrugated ribs and the comparatively slow warming of the side parts. The outermost corrugated rib layer abutting the side parts, opposite to the charge air flow, is displaced forward over the intake edge of the fin-tube block into the intake area for the charge air formed in the side parts and water tanks. In this way, more rapid heating of the side parts can be achieved.
