1. A heat exchanger comprising:
a first fluid carrying conduit of a gas turbine extending along a first conduit axis and configured to convey a first fluid at a first temperature;
a second fluid carrying conduit of the gas turbine extending along a second conduit axis and configured to convey a second fluid at a cooler, second temperature;
a first fin having a first opening for coupling to the first fluid carrying conduit and a second opening for coupling to the second fluid carrying conduit, the first fin extending along a first fin axis that subtends an acute angle or obtuse angle with at least one of the first conduit axis or the second conduit axis to transfer heat from the first fluid carrying conduit to the second fluid carrying conduit that exits the heat exchanger; and
a second fin having a first opening for coupling to the first fluid carrying conduit and a second opening for coupling to the second fluid carrying conduit, the second fin extending along a second fin axis that subtends an acute angle or obtuse angle with at least one of the first conduit axis or the second conduit axis and positioned adjacent to and aligned with the first fin along the first conduit axis and the second conduit axis to transfer heat from the first fluid carrying conduit to the second fluid carrying conduit that exits the heat exchanger.
