HEAT EXCHANGER, IN PARTICULAR EXHAUST GAS COOLING DEVICE, FOR COOLING EXHAUST GAS FROM AN INTERNAL COMBUSTION ENGINE

The invention concerns a heat exchanger (1), in particular an exhaust gas cooling device, for cooling exhaust gas from an internal combustion engine. The heat exchanger (1) comprises a housing (2) which comprises a circumferential wall (4) and two end housing walls (5a, 5b) which together define a housing interior space (3), the circumferential wall (4) having a coolant inlet (11) for introducing a coolant (K) into the housing interior space (3). The heat exchanger (1) comprises a plurality of tubular bodies extending along a longitudinal direction (L) and arranged in the housing interior for the passage of exhaust gas. The heat exchanger (1) further comprises at least one housing insert (7a, 7b) arranged in the housing interior between the tubular bodies and the peripheral wall (4). An opening (12) through which the coolant (K) can flow is formed in the housing insert (7a, 7b), preferably at a distance from the coolant inlet (11).
