What specific functions does the fresh water cooling system have for protecting the internal components of the H-MG15i 12kW Marine Inverter Diesel Permanent Magnet Generator?

The fresh water cooling system has multiple specific functions for protecting the internal components of the H-MG15i 12kW Marine Inverter Diesel Permanent Magnet Generator. The fresh water cooling system takes away the heat generated inside the generator through the heat exchanger, effectively reducing the temperature of key components such as the generator cylinder, piston, and cylinder head. These components will generate a lot of heat when running at high speed. If they cannot be dissipated in time, they will cause the components to overheat, which will affect the performance and life of the generator. The fresh water cooling system can maintain the stability of the internal temperature of the generator and prevent damage to the generator due to excessive temperature fluctuations. A stable temperature environment helps the generator operate under optimal conditions and improve power generation efficiency and reliability.
High temperature can cause thermal stress in the metal parts inside the generator, and long-term accumulation can cause deformation, cracks, and even fracture of the parts. The fresh water cooling system reduces the generation of such thermal stress by dissipating heat in time, thereby extending the service life of the components. Excessive temperature will also accelerate the oxidation and deterioration of the lubricating oil inside the generator, reducing its lubrication performance. The fresh water cooling system helps to maintain a moderate temperature inside the generator, prevents the lubricating oil from deteriorating too quickly, and protects the lubrication and wear of the various components of the generator.
The appropriate cooling temperature helps to optimize the combustion process of the diesel engine and improve the combustion efficiency. The improvement in combustion efficiency means that more electricity can be generated under the same fuel consumption, thereby improving the overall operating efficiency of the generator. The combustion process of the diesel engine in a high temperature environment is prone to produce harmful emissions such as nitrogen oxides. The fresh water cooling system helps to reduce the generation of these harmful emissions by controlling the internal temperature of the generator, which meets environmental protection requirements.
In the marine environment, the seawater cooling system is susceptible to corrosion and clogging caused by salt erosion. The fresh water cooling system avoids this problem, allowing the generator to operate stably in the marine environment. Since the fresh water cooling system is not prone to scaling and clogging, the workload of cleaning and maintenance is reduced, and the maintenance cost is reduced.
The fresh water cooling system plays a vital role in protecting the internal components of the H-MG15i 12kW Marine Inverter Diesel Permanent Magnet Generator. It can not only effectively control the temperature, extend the life of components, and improve operating efficiency, but also adapt to harsh environments and reduce maintenance costs.
