Study on the Characteristics of Heat Exchanger for Cold Energy Recovery in LNG Vehicles

Abstract LNG (Liquefied Natural Gas) vehicles, which are the transport of disposing of urban pollution, have the advantages of high thermal efficiency and less pollution. Another advantage of LNG vehicles is that the cold energy of the fuel LNG can be recycled for air conditioner. Based on the two fluid model, numerical simulation of the heat transfer characteristics of cold energy recovery heat exchanger in LNG vehicle are carried out. The results can provide a reference for the design of cold energy recovery heat exchanger in LNG vehicle.
