Description
Technical field
The utility model relates to a kind of cooling device, in particular to a kind of compressed air type hydraulic oil cooling device.
Background technique
Underground coal mine environmental quality is that air humidity is big, and getting working face temperature is high, floating material, dust coal in air
Dirt, inflammable gas equal size are higher.With mine gradually in depth under, influenced by underground heat it is also increasingly severe, from ground
It counts, 13 meters of temperature rises of every decline just have 0.5 DEG C -1 DEG C, and many 500 meters reach 40 DEG C with the maximum temperature that goes down into a mine, and seriously affect work
The health and working efficiency of people.Due to the particular surroundings and condition of mine, common cooling system not may be used in mine,
So mine cooling has also just put on schedule.Wherein mechanical equipment heat release is an important heat source of mechanization mine.Electromechanics is set
Standby whole idle works are converted into heat, part useful work in addition to being converted into potential energy in fragmented rock body and lifting ore, remaining
Part is also converted to heat.In down-bound conveyance, institute's consuming electric power and potential variation amount are completely converted into heat；When uplink is transported, consumed
Electric energy a part is converted into potential energy, and residue is converted into heat.There are about 80% to be converted into heat for coal cutting machinery institute wasted work rate.Comprehensive mechanical
