Summary of the invention
Technical problem to be solved in the utility model provides a kind of both conserve space, again the hybrid power bulldozer cooling system of good cooling results.
The technical scheme that the utility model adopts is:
A kind of hybrid power bulldozer cooling system, it comprises air-air charge air cooler, comprehensive radiator, the engine water radiator, hydraulic oil cooler and cooling fan, the main pump motor of hybrid power bulldozer, turning motor, generator, electric machine controller passes through electric water pump, comprehensive radiator, the hydraulic oil cooler consists of a loop, the motor of hybrid power bulldozer carries water pump by engine water radiator and motor and forms a loop, the motor of hybrid power bulldozer and air-air charge air cooler form a loop, and described cooling fan is to high temperature circulation water in the engine water radiator, high temperature water in the comprehensive radiator, hot air cools off in the air-air charge air cooler.
Press such scheme, described cooling system also includes three thermostats, first thermostat places between motor and the air-air charge air cooler, second thermostat places between motor and the engine water radiator, the 3rd thermostat places between hydraulic oil cooler and the comprehensive radiator, and described three thermostats are connected with cooling fan.
Press such scheme, described comprehensive radiator, engine water radiator are installed with air-air charge air cooler after welding successively from outside to inside more side by side.
Operating principle of the present utility model is:
The engine water radiator carries the heat that produces when water pump is connected afterwards engine operation by pipeline and motor and takes away by cooling fan, forms the high temperature circulation loop; The heat that hydraulic oil produces is passed to comprehensive radiator to heat by oil, the hydrothermal exchange of hydraulic oil oil cooler; By pipeline hydraulic oil oil cooler, electric machine controller, generator, turning motor, main pump motor, electric water pump etc. are coupled together, and the heat that produces during its work taken away by cooling fan by comprehensive radiator, form the low-temperature circulating loop; Be transported to air-air charge air cooler by the hot air of pipeline after engine booster, then cooling fan is taken away its heat.Described cooling system also includes three thermostats, first thermostat places between motor and the air-air charge air cooler, second thermostat places between motor and the engine water radiator, the 3rd thermostat places between hydraulic oil cooler and the comprehensive radiator, and described three thermostats are connected with cooling fan.Fan can be according to variations in temperature automatic speed regulation, adopts relation in parallel between three temperature, namely just begins to carry out " opening " when a temperature reaches lower bound value of opening of expection setting, and from " opening " to " standard-sized sheet " carries out linear regulation, to the ceiling value standard-sized sheet.Only have when three tunnel temperature all are lower than " opening " temperature, carry out all " pass ".
The beneficial effects of the utility model are: 1, different thermal source parts are cooled off separately, guaranteed that their operating temperature is in tolerance band separately.2, cooling fan can be according to variations in temperature automatic speed regulation, and is not only energy-conservation, and can reach cooling effect.3, effectively solve poorly sealed, the problem such as leak out between the radiator, reduce the space and arrange.4, improved the cooling effect of cooling system.
