A heat exchanger arrangement for a gas turbine engine. The arrangement including a flow path 31 within an outer cowl 32, which flow path 31 locates a heat exchanger 43 part way therealong. A valve 38 is provided at an inlet end of the flow path 31 to selectively receive fluid into the flow path 31 from outside of the cowl 32 and/or from a pressurised fluid flow 36. An exit 34 from the flow path 31 comprises a plenum chamber to receive exhausted coolant flows from the heat exchanger 43 and possibly other exhaust flows. The heat exchanger exhaust flow 34 is then utilised to provide cooling to engine structures. |
