The heat exchanger has a housing defined by a casing 10 and end assemblies defined by a collar 11, 12 and a respective end cap 13, 14. Tubes 19 extend through the housing and communicate with an inlet 26 and an outlet 27 defined by the end caps 13 and 14 respectively. A radial inlet 28 and a radial outlet 29 are provided in the collars 11 and 12, respectively. Baffles 31 and 33 are of semi- cylindrical shape and are defined by extensions of the casing 10. These baffles 31 and 33 are spaced inwardly of the inlet 28 and outlet 29 respectively and define openings which are circumferentially spaced from the inlet 28 and outlet 29. The incoming stream of fluid impinges against the baffle 31 so that erosion effects are largely dissipated. The baffle 33 is provided to serve the same effect in the event that the flow is reversed so that the roles of the inlet 28 and outlet 29 are reversed. <IMAGE>
