A heat exchange arrangement (40) for a gas turbine engine (10). The arrangement (40) comprises a first conduit (46) for an engine component cooling fluid and a second conduit (44) for a second fluid. The arrangement further comprises a heat exchange portion (42) in which fluids flowing through the first and second conduits (46, 44) are in a heat exchange relationship. A valve 48 is provided, which is configured to moderate the mass flow rate of one of the fluids through the heat exchange portion (42). The arrangement comprises divert valve in the first conduit which diverts flow to the second conduit as the flow in the second conduit is moderated to reduce thermal shock in the heat exchange portion. |
