[0029] The working principle of the multi-media integrated titanium alloy plate-fin heat exchanger for amphibious vehicles of the utility model is as follows:

[0030] The heat exchanger consists of a high-temperature fresh water module, a main transmission oil module and a water transmission oil module. The main transmission oil module and the water transmission oil module are in series, forming a two-in-one module after series connection. The two-in-one module and the high-temperature fresh water module are in parallel. After entering the heat exchanger, seawater enters the two-in-one module and the high-temperature fresh water module at the same time. After entering the two-in-one module, seawater first enters the water transmission oil module, and then enters the main transmission oil module. After sufficient heat exchange, the seawater flows out of the heat exchanger. When the heat exchanger is working, high-temperature fresh water, main transmission oil, and water transmission oil enter the corresponding hot side channels respectively, and seawater enters the seawater channel. The temperature of seawater is lower than that of the heat medium. The flowing seawater fully takes away the temperature of the heat medium, which plays a role in heat exchange and cooling. The three independent heat exchangers are integrated into one heat exchanger, which greatly reduces the total mass of the heat exchanger and the space occupied in the vehicle body. Integrating into one heat exchanger also reduces the layout of the vehicle body pipelines and saves the space occupied by the heat exchanger. At the same time, the selection of titanium can fully meet the requirements of seawater corrosion resistance.
