The cooling system of the existing underwater bulldozer utilizes the water environment in which the cooling system is located to exchange heat and cold for cooling liquid (as shown in fig. 2), but the cooling system is obviously not suitable for land use, so the design concept of the scheme is to add an auxiliary cooling system for the underwater bulldozer, and the underwater bulldozer can also be used on land.
The cooling routes of the present application are three:
the first is a cooling route of the underwater bulldozer during underwater operation: the water suction port, the filter, the tee joint I, the water pump, the cold and heat exchanger, the engine, the cold and heat exchanger, the water storage tank, the tee joint II and the water discharge port are sequentially arranged on the water suction port.
