An exhaust gas recirculation cooler may include a heat exchanger block including a first mounting flange, a diffuser including a second mounting flange, and at least one non-return valve arranged between the heat exchanger block and the diffuser. The exhaust gas recirculation cooler may also include a valve carrier which supports the at least one non-return valve and on which a gasket is arranged. The heat exchanger block may be connected via the first mounting flange directly to the second mounting flange of the diffuser. The valve carrier may be arranged between the heat exchanger block and the diffuser, and with the gasket may seal a sealing point between the first mounting flange and the second mounting flange. The diffuser may include an outwardly closed recess with a peripheral rim structured to accommodate the valve carrier. The rim may define the second mounting flange.

A heat management system is provided for an automotive system having a plurality of heat manageable components. The heat management system includes a plurality of heat transferring path having a plurality of heat pipes, and a heat exchanger for each of the heat manageable component of the automotive system. The heat pipes are configured to transfer heat from at least one of the heat exchanger to another heat exchanger.

A process for producing an amorphous ductile brazing foil is provided. According to one example embodiment, the method includes providing a molten mass, and rapidly solidifying the molten mass on a moving cooling surface with a cooling speed of more than approximately 10.sup.5 C./sec to produce an amorphous ductile brazing foil. A process for joining two or more parts is also provided. The process includes inserting a brazing foil between two or more parts to be joined, wherein the parts to be joined have a higher melting temperature than that the brazing foil to form a solder joint and the brazing foil comprises an amorphous, ductile Ni-based brazing foil; heating the solder joint to a temperature above the liquidus temperature of the brazing foil to form a heated solder joint; and cooling the heated solder joint, thereby forming a brazed joint between the parts to be joined.
