HEAT TRANSFER DEVICE AND ASSEMBLY FOR EXHAUST GAS RECIRCULATION HAVING SAID HEAT TRANSFER DEVICE

WIPO Patent Application WO/2011/095382

A3

The invention relates to a heat transfer device (10) comprising at least two housing parts (11, 15), wherein the housing parts (11, 15) are connected to each other such that at least one channel (16) through which a fluid to be cooled can flow and at least one channel (18) through which a cooling fluid can flow are arranged in heat-exchanging contact to each other, wherein ribs (20) extend from at least one of the housing parts (11, 15) into the channel (16) through which fluid to be cooled can flow, and wherein the ribs (20) are interrupted in the primary flow direction of the fluid to be cooled. According to the invention, the channel (16) of the heat transfer device (10) through which the fluid to be cooled can flow is divided perpendicularly to the extension direction of the ribs (20) in a first channel (22) and a second channel (24). The invention further relates to an assembly for exhaust gas recirculation having said heat transfer device (10), wherein one non-return valve is arranged downstream of each of the first and second channels (22, 24).
