The invention discloses a Brayton cycle integrated heat exchanger of an underwater vehicle and a heat exchange method. The Brayton cycle integrated heat exchanger comprises a heat return module and a pre-cooling module. The heat regeneration module comprises a plurality of heat flow plates and cold flow plates which are alternately stacked, the precooling module is arranged outside the heat regeneration module in a sleeving mode, and a vacuum heat insulation cavity is formed between the precooling module and the heat regeneration module. The heat exchanger and a shell of the underwater vehicle are integrally machined, the heat exchanger serves as a part of the heat exchanger, the thickness of the shell of the underwater vehicle is increased, the pressure resistance of the shell of the underwater vehicle is improved, meanwhile, the thickness of the shell of the underwater vehicle can be reduced, and the self weight of the underwater vehicle is reduced; after primary heat exchange is carried out on the hot fluid and the cold fluid in the heat regenerator, the hot fluid and the cold fluid enter the precooler to carry out secondary heat exchange with external seawater, the heat exchange efficiency is improved, coupling is reduced through the vacuum heat insulation cavity, a deformation space is reserved for thermal expansion of the heat regenerator, and the operation safety of the underwater vehicle is improved.

    本发明公开了一种潜航器的布雷顿循环一体式换热器及换热方法,包括回热模块和预冷模块;所述回热模块包括若干个交替叠置的热流板和冷流板,所述预冷模块套设在回热模块的外部,并且预冷模块与回热模块之间有真空隔热腔;该换热器与潜航器的壳体一体加工,换热器作为换热器的一部分,增加了潜航器的壳体厚度,提高其抗压能够,同时可以减小潜航器壳体的厚度,降低潜航器的自身重量,回热模块与预冷模块之间设置真空腔,热流体与冷流体在回热器进行一次换热后,然后进入预冷器与外界的海水进行二次换热,提高了换热效率,通过真空隔热腔降低了耦合,并为回热器的热膨胀预留变形空间,提高潜航器的运行安全。
