How to recover waste heat from ship engines

Ship engines and other equipment generate a large amount of waste heat during operation, which is usually discharged into the environment through cooling water and other means, resulting in energy waste. Heat exchangers can transfer waste heat to other media, such as transferring the heat from engine cooling water to hot water or hot oil systems, for use in ships' hot water supply, heating, or other places that require thermal energy.
Our heat exchanger adopts high-efficiency heat transfer materials and innovative structural design, with excellent heat exchange efficiency. The core components are made of special metal alloy materials, greatly improving thermal conductivity. At the same time, the optimized flow channel design allows hot and cold fluids to fully contact inside the heat exchanger, ensuring that waste heat can be quickly and efficiently transferred. Taking the waste heat recovery of ship engines as an example, when the high-temperature cooling water generated by the engine flows into one side of the heat exchanger, the low-temperature medium (such as hot water or hot oil) on the other side exchanges heat with it. Through the efficient operation of our heat exchanger, the heat of the cooling water can be fully extracted for use in ship hot water supply, cabin heating, and other applications.
