Abstract
The invention discloses a liquid cooling system. The liquid cooling system comprises a gas flow channel, a liquid circulation loop and a control apparatus. The gas flow channel comprises an engine, a turbine, a heat exchanger and a gas circulation pipeline. Compressed air from the engine enters into the turbine and expansion cooling is performed. And then the air passes through a cold-path pipeline of the heat exchanger and is discharged from an exhaust duct of the engine. The liquid circulation loop comprises a liquid storage box, a liquid pump, the heat exchanger, equipment to be cooled and a liquid circulation pipeline. The turbine drives the liquid pump through a driving shaft. The liquid pump extracts liquid from the liquid storage box. After the liquid passes through a heat path of the heat exchanger, heat is taken away by a cold path so that cooling to the equipment to be cooled is realized. The system has an advantage that the liquid cooling system uses the compressed air of the engine as a power source so that conversion times of airplane energy are reduced and system losses are decreased.
