The invention provides a heat exchange loop and a heat exchange system of a hybrid power aircraft, relates to the technical field of aircraft heat management, and is used for transmitting cold energy to required heat dissipation equipment, realizing heat dissipation of the equipment and ensuring stable and safe operation of aircraft system equipment. The heat exchange loop comprises a cold side flow path and a hot side flow path, and the cold side flow path and the hot side flow path are connected through a shared mixed liquid heat exchanger. The cold side flow path is composed of the mixed liquid heat exchanger, a wing oil tank and a first electric drive pump which are sequentially connected end to end. The hot side flow path is composed of the mixed liquid heat exchanger, a liquid storage tank, a second electric drive pump, a DC/DC converter and a propulsion motor controller which are sequentially connected end to end. Wherein the cold side flow path is driven by the first electric drive pump to achieve cold side fuel oil circulation, and the hot side flow path is driven by the second electric drive pump to achieve hot side fuel oil circulation.
