1. A swirl recovery vane (SRV) comprising:
a trunnion configured to connect to an exterior surface of an inner platform of an SRV structure system;
a body that extends radially from the trunnion to an unshrouded distal SRV tip of the SRV;
a heat exchanger located within the SRV, the heat exchanger comprising:
a gas inlet configured to couple a bleed air valve of a stage of a high or low compressor section of a gas generator to a gas channel;
the gas channel adapted to:
enable gas to flow in through the gas inlet as cool gas and out through a gas outlet as warm gas; and
extend into the body of the SRV to enable heat transfer from a heat source within the SRV to the cool gas; and
the gas outlet that outputs the warm gas from the gas channel to an ambient environment outside of the SRV.
