The invention relates to a soldered aluminum heat exchanger, having tubes made of a core material through which tubes a coolant flows, and said tubes being connected to at least one header by means of an inner soldered joint; having a protective plating on the inner face of the core material comprising aluminum and using four-layer technology; having an inner solder plating on the protective plating; and having an outer solder plating on the outer face of the tube facing away from the coolant face.
摘要:
The invention relates to an exhaust gas heat exchanger for motor vehicles, comprising a cluster of exhaust pipes (10) which are soldered on the front surface thereof to pipe bottoms, and a housing jacket (3, 3b) which is welded to the pipe bottoms (7). According to the invention, the pipe bottoms are welded to the housing jacket (3b) by means of peripheral welds (11).
摘要:
The invention relates to a device for cooling a gas flow of an internal combustion engine, comprising a housing (1), an inlet (3) and an outlet (4) for a gas, in particular exhaust gas and/or charge air of the internal combustion engine, which is to be cooled, an inlet (18) and an outlet (16) for an in particular liquid coolant, an exchanger means (5) for heat transfer between the gas and the coolant, a first wall section (1 a) of the housing (1), wherein the first wall section (1 a) is arranged between the coolant and the gas flow, and a second wall section (1 b) of the housing (1), wherein the second wall section (1 b) is arranged between the coolant and an environment, in particular the atmosphere, wherein the first wall section (1 a) and the second wall section (1 b) are materially integrally formed in one piece.
