Cold-heat separation unattended generator set

The invention provides a cold-heat separation unattended generator set. A lower cavity, a left cavity and a right cavity are formed in a box body, wherein the lower cavity, the left cavity and the right cavity are in cold-heat separation. An electric control assembly is arranged in the colder left cavity, an engine is installed in the hotter right cavity, the air-cooled engine is arranged to drawair from the left cavity, the cold air cools the electronic control assembly with a lower temperature for the first time, and then an engine cylinder with a higher temperature is cooled to prevent engine heat accumulation, the electronic control assembly can further be cooled to make full use of the cooling capacity; and the cold air passes through the engine cylinder with the higher temperature and finally cools a muffler with a higher temperature to further utilize the cooling capacity. 本发明提出了一种冷热分离无人值守发电机组，通过在箱体内设置冷热分离的下腔体、左腔体和右腔体，将电控组件设置于较冷的左腔体内，发动机设置于较热的右腔体，设置风冷发动机，从左腔体内吸气，冷风对温度较低电控组件进行初次冷却后，再对温度较高的发动机汽缸进行冷却，防止发动
