Background
With the rapid development of industry and commerce, there is an increasing demand for efficient, reliable generator sets. Overheating is a common and critical problem in the operation of a generator set, which not only affects the efficiency of the equipment, but can also lead to equipment damage, increased maintenance costs and downtime.
The generator sets generate a lot of heat in operation, mainly due to the internal combustion process and the conversion of mechanical energy. This heat, if not managed effectively, can lead to reduced device performance and even possible damage to critical components. Traditionally, gensets rely on water or air cooled systems for heat dissipation, which, while excellent in cooling efficiency, present challenges in terms of maintenance, cost and environmental flexibility. In contrast, air-cooled systems are favored for small or medium-sized generator sets because of their simple structure and low maintenance requirements.
Nevertheless, existing air-cooled systems also have significant limitations. These systems typically rely on external fans or built-in cooling mechanisms to dissipate heat, which often are too simple in design, resulting in poor cooling efficiency under high loads or extreme environmental conditions. Furthermore, these systems can cause noise problems and often do not cool effectively against a particular hot spot, which further limits their use under severe conditions.
In this context, it has become important to develop a new cooling technology that provides both efficient cooling and is adaptable to a variety of environmental conditions.
