Abstract: The present invention relates to a heat exchange device for exchanging heat between two fluids circulating through insulated conduits. In the preferred example the first fluid is a hot gas originating from an exhaust gas recirculation (EGR) system, and the second fluid is a coolant liquid used for removing heat from the hot gas. The device according to the invention has a simple and cheap construction, lacking a shell, formed by a plurality of extruded aluminum profile segments attached by clad plates arranged perpendicularly giving rise to a very compact and light-weight configuration when it is in an operating mode.

Abstract: The present invention relates to a heat recovery device particularly suitable for internal combustion engines, and more particularly suitable for engines incorporating a WHRS (waste heat recovery system). The device of the invention relates to the occasional recovery of heat from the exhaust gases where the invention carries out this function such that the main conduit where the exhaust gases circulate is not affected by a noticeable increase in heat loss due to the incorporation of said device. It provides a heat exchanger (3.6) and a bypass flap valve (3.8) upstream for selectively diverting the exhaust gases to the main exhaust conduit (1) or to the heat exchanger (3.6).

Abstract: The present invention is a device for heat exchange particularly suitable for cooling recirculated gas in EGR (Exhaust Gas Recirculation) systems, with a constructive configuration incorporating the heat exchanger together with a bypass conduit and a bypass valve, where most of the parts forming said device allow manufacturing same in stamped sheet metal, thereby reducing manufacturing costs.

Abstract: 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.
