Preferably, diesel engine needs the position of cooling to comprise cylinder sleeve and cylinder cap.
Preferably, the cooling line on cylinder sleeve is around the outer wall of cylinder sleeve.
Preferably, the cooling line be looped around on cylinder sleeve comprises 1 to 3 group around unit, and often group is around cell rings around the some circles of cylinder sleeve, all merges into house steward around the intake pipe of unit and outlet pipe.
Preferably, what the cooling line on cylinder cap bent is built in the entity part of cylinder cap.
Preferably, access decompressor in circulation loop, this decompressor is used for externally doing work.
Preferably, access condenser in circulation loop, the steam through decompressor enters condenser.
Preferably, the downstream of condenser is connected to liquid container, and this liquid container is used for storing liquid cooling water, and liquid cooled water continues circulation by automatically controlled compression pump.
Preferably, radiator and recycle pump is connected in the outer circulation loop of condenser.
Compared with prior art, the present invention has following beneficial effect: by designing a kind of type of cooling cooling cooling line coverage goal part, the boiling type of cooling is adopted to diesel engine difference cooling position, cooling water is gasified absorb heat, hold more heats, done work by decompressor, waste heat is easily recycled.In addition, compression pump adopts electric drive, and the intensification avoiding traditional cooling system is slow, seal request is high, the shortcoming of water cavity easy-to-rust, and the power source no longer direct correlation engine operation condition of pump, can independently control.
