摘　　要：针对船用柴油发电机组在停机后仍有大量热量辐射至机舱,严重影响机舱舒适性的问题,以某型船舶柴油发电机组为对象,设计了一套余热冷却系统,在柴油发电机组停机后对缸套等高温部位进行冷却。经相关试验验证:该冷却系统可有效降低柴油发电机组停机后的温度,且具有操作简单,维护方便,自动控制等特点。Lots of exhaust heat radiates to the engine room when the marine diesel gensets shut down,which may badly influence the comfort of the engine room.A set of exhaust heat cooling system was designed for a type of marine diesel gensets,which can cool the high-temperature parts,such as cylinder liners,as the marine gensets shut down.Tests show that this cooling system can effectively reduce the temperature of the diesel gensets as they shut down,and features simple operation,easy maintenance and automatically control.
