An intercooler assembly may include a housing and a cooler arranged therein through which charge air may be flowable. The housing may include an insertion opening through which the cooler may be insertable into the housing in an insertion direction transverse to the flow direction of the charge air. The cooler may include a pipe structure through which a coolant may be flowable, first and second end parts opposite each other transverse to the insertion direction, and third and fourth end parts opposite each other transverse to the first and second end parts and parallel to the flow direction, the end parts laterally delimiting and mechanically connected to the pipe structure. The cooler may be mechanically connected to the housing by the first end part, and at least one of the other end parts may be movably attached to the housing. The cooler may be pre-stressed against the housing by the third and/or fourth end part in a direction opposite a deformation of the cooler resulting from cooling of the charge air.

A heat exchange device suitable for cooling recirculated exhaust gases in an EGR (Exhaust Gas Recirculation) system includes a configuration which allows integrating the heat exchanger in a cavity of the engine block of an internal combustion engine with the cavity being in fluid communication with the liquid coolant of the engine.

Shell and tube heat exchanger (1) comprising a first outer shell (2) and a tube bundle (3), inlet and outlet interfaces communicating with the shell side and with the tube side for a first fluid and for a second fluid respectively, wherein the exchanger comprises a second shell (4) which is inside said first shell (2) and surrounds said tube bundle (3); said second shell (4) comprises at least one releasable longitudinal joint (32) and a plurality of longitudinal sections connected by releasable joints; said second shell (4) delimits the shell side of the exchanger (1) around said tube bundle (3), and further defines a flushing interspace (5) communicating with said shell side, said first fluid flows through said shell side along one or more longitudinal passages, and said first fluid and said second fluid are counter-current along said one or more longitudinal passages.

A heat exchanger is comprised of two heat exchanger sections, at least one of which is provided with a floating header to accommodate differential thermal expansion. The two heat exchanger sections are enclosed by an inner shell wall, and an external connecting passage is provided outside the inner shell wall, through which one of the fluids flows between the two heat exchanger sections. The external connecting passage is enclosed by an outer shell. The inner wall is provided with openings which communicate with the external connecting passage. The openings may be in the form of a substantially continuous gap or discrete openings. Specific examples of heat exchangers with this construction include a steam generator, a steam generator and combined catalytic converter, and a water gas shift reactor.

The present invention proposes a new design in the configuration of the attachment between the battery of tubes and the shell of a heat exchanger, improving the manufacturing costs and efficiency with respect to the exchangers of the state of the art. The present invention describes a heat exchanger and a process for manufacturing it, which combines the thermal fatigue strength of floating core exchangers with the compact, simple and more economical design of monoblock exchangers, resulting from, among others, a smaller number of necessary manufacturing steps.

A heat exchanger for cooling of charge air for an internal combustion engine of a motor vehicle is provided. The heat exchanger has a preliminary stage, a main stage, and a compensating component. The preliminary stage has at least one preliminary stage fixed bearing base and a preliminary stage floating bearing base. The main stage has at least one main stage fixed bearing base and a main stage floating bearing base. In a heat transfer region of the main stage, at least one main stage channel for a main stage coolant is disposed. The compensating component is configured to compensate a position difference between corresponding components of the preliminary stage and the main stage, whereby the position difference is based on a thermally induced elongation difference between the at least one preliminary stage channel and the at least one main stage channel.
