[0002] When emergency engineering vessels are performing missions, their generator sets need to operate continuously and stably to provide sufficient power. However, the generator sets generate a lot of heat during operation. If the heat cannot be dissipated in a timely and effective manner, the unit temperature will become too high.

Therefore, it is necessary to install cooling devices at the generator sets of emergency engineering vessels.
