Abstract
A combination fuel-oil and air-oil heat exchanger comprising: a first heat exchanger section that has an oil circulation path and a fuel circulation path thermally coupled to the oil circulation path; a second heat exchanger section that has an oil circulation path and an air circulation path thermally coupled to the oil circulation path; an oil coupling path that couples an oil circulation path outlet of the first heat exchanger section to an oil circulation path inlet of the second heat exchanger section to establish a combined oil circulation path; an oil path by-pass valve that selectively diverts oil from the combined oil circulation path to an outlet of the oil path by-pass valve; and a fuel path by-pass valve that selectively diverts fuel from the fuel circulation path of the first heat exchanger section to an outlet of the fuel path by-pass valve.
