The embodiment of the invention provides a marine diesel power system which comprises a diesel engine, a conformal heat exchanger and a jet device, and a first inlet and a first outlet of the conformal heat exchanger are connected with the diesel engine; a second inlet of the conformal heat exchanger is used for flowing seawater, and a second outlet is used for discharging seawater; the jet deviceis arranged at the second outlet of the conformal heat exchanger, the first inlet of the jet device is used for sucking seawater discharged from the second outlet of the conformal heat exchanger, thesecond inlet of the jet device is connected with the diesel engine exhaust pipe, and the outlet of the jet device is used for discharging seawater and waste gas discharged from the diesel engine exhaust pipe of the diesel engine. According to the marine diesel power system provided by the embodiment of the invention, the jet device is arranged at the second outlet of the conformal heat exchanger,and under the action of turbulent diffusion, the heat exchange form of the conformal heat exchanger is changed into forced convection heat exchange, so that the flow rate of outboard seawater is increased, and the heat exchange efficiency of the conformal heat exchanger is improved.

    本发明实施例提供一种船舶柴油动力系统,包括:柴油机、共形换热器和射流装置,其中,共形换热器的第一入口和第一出口分别与柴油机连接;共形换热器的第二入口用于流入海水,且第二出口用于排出海水;射流装置设置在共形换热器的第二出口处,射流装置的第一入口用于吸入由共形换热器的第二出口排出的海水,射流装置的第二入口与柴油机排气管连接,射流装置的出口用于排出海水和柴油机的柴油机排气管排出的废气。本发明实施例提供的船舶柴油动力系统,通过在共形换热器的第二出口处设置射流装置,在湍动扩散作用下,使共形换热器的换热形式变为强制对流换热,提高了舷外海水的流动速率,从而提高了共形换热器的换热效率。
