Abstract: The invention relates to an exhaust gas recirculation cooling element (1) comprising a heat exchanger (2) having several heat exchange units (11, 12, 13) that are introduced between the inflow region (3) and the outflow region (7) of the exhaust gas (AG). Said units comprise cooling tubes with cooling ribs. The heat exchanger (2) is surrounded by a housing (16), the lateral walls thereof (19) being arranged at a distance in relation to the perforated lateral walls (10). Guide channels (28) are arranged between the closed lateral walls (9) of the heat exchanger (2) and the adjacent lateral walls (20) of the housing (16), said guide channels extending in a diagonal manner and being provided to direct the coolant (KM) from a coolant inlet to the coolant outflow through the individual heat exchange units (11, 12, 13).
