For solving the problems of the technologies described above, the technical solution adopted in the present invention is: the cooling system that a kind of water-cooled diesel engine integrated form axle center is arranged symmetrically with, comprise diesel-engine body, cooling waterpump, intercooler and radiator, diesel-engine body comprises bent axle, the through diesel-engine body of bent axle, one end of bent axle is clutch end, the other end is free end, and cooling waterpump is integrated on diesel-engine body, and water intake and the water outlet of cooling waterpump are connected water outlet and the water intake of diesel-engine body respectively;
Intercooler is fixed on the clutch end of diesel-engine body, and the suction port of intercooler is connected with the pressurized machine at the exhaust outlet place being arranged on diesel-engine body, and the air outlet of intercooler is connected with the suction tude of diesel-engine body;
Radiator is fixed on the free end of diesel-engine body, and intake pipe and the outlet pipe of radiator are connected water outlet and the water intake of diesel-engine body respectively, and intake pipe and the outlet pipe of radiator are also connected outlet pipe and the intake pipe of intercooler simultaneously.
The further improvement of technical solution of the present invention is: radiator and intercooler are symmetrical relative to the bent axle cross central line of diesel-engine body.
The further improvement of technical solution of the present invention is: diesel-engine body is also provided with the second water pump, and the second water pump connects the belt pulley of diesel-engine body by belt.
The further improvement of technical solution of the present invention is: the water outlet of diesel-engine body is also provided with thermostat.
Owing to have employed technique scheme, the technological progress that the present invention obtains is:
1, radiator, intercooler are integrated on diesel-engine body, increase by the second water pump, adopt water water cooling pattern, eliminate the design of fan, substantially reduce the volume of cooling system, diesel-engine body centre distance is little, compact structure, rigidity improves, weight saving, is convenient to install.
2, radiator, intercooler lay respectively at free end and the clutch end of diesel-engine body, the connection application pipeline of radiator and intercooler is few, water route, gas circuit linear loss are little, intercooler is positioned at this correct position of clutch end relative to diesel-engine body, and then the pipeline corner of gas handling system can be reduced, thus reduction resistance of air, improve intake efficiency; Decrease the risk that cooling liquid is leaked, system cloud gray model is safer, stable simultaneously.
3, radiator, intercooler are symmetrical relative to the bent axle cross central line of diesel-engine body, diesel-engine body barycenter does not change, the balanced weight distribution of diesel-engine body component on diesel-engine body, reduce the assembling difficulty of vibrations and later stage diesel-engine body, be convenient to diesel-engine body integral hoisting; The corresponding minimizing of parts mix selection model, cost reduces further; And work is more stable during diesel-engine body running, ride quality is higher.
4, the second water pump is also provided with, for user's practical application.Because the present invention is used in marine diesel engine, cooling requires higher, therefore adds the second water pump and improves cooling effect further; Thermostat is arranged on the water outlet of diesel-engine body, can accurately controlled cooling model liquid temp.
