Abstract
The invention relates to a novel cooling system of a hybrid power excavating machine. In the invention, a water radiator, an integrative radiator and an air-to-air intercooler are designed as an independent circulation loop respectively, thus ensuring respective working temperature thereof within respective permission scope. The integrative radiator and the water radiator are successively arranged from outside to inside, and are welded with the air-to-air intercooler respectively, thus effectively solving the problems of poor sealing, ventilation leakage and the like between the radiators, improving the cooling effect of the cooling system, and reducing space arrangement. In addition, the complete machine system is simple, reliable and practical.
Description
Technical field
The present invention relates to a kind of design of Cooling System of hybrid excavator.
Background technique
The cooling system that uses on the excavator all is to adopt motor to carry the water pump cooled engine basically at present, the hydraulic system cooling utilizes air cooling, and cooling system adopts high and low temperature circulation cooling on the hybrid excavator: promptly electric water pump circulating water cools off low temperature component such as hydraulic system and electrical apparatus element, and motor carries the water pump cooled engine.
Summary of the invention
Hybrid excavator is on CN220 chassis of dredging machine and traveling gear technical foundation, for adapting to the novel engineering machinery that the utilization of national energy-conserving and emission-cutting technology on excavator developed.Whole cooling system not only will cool off motor, hydraulic system and engine booster air, simultaneously because complete machine has increased component such as generator, electric machine controller, main pump motor, turning motor and cooled off, and its operating temperature is the same with hydraulic system all requires below 85 ℃.
Heat radiation needs when working for satisfying above-mentioned each component, the present invention is water radiator, comprehensive radiator, the absolutely empty intercooler independent loops loop that is designed to respectively do for oneself, by pipeline engine water radiator and motor are carried water pump and be communicated with, cooling fan cools off high temperature circulation water in the engine water radiator; After the oil of hydraulic system by the hydraulic oil cooler, the hydrothermal exchange, by pipeline generator, electric machine controller, main pump motor, turning motor, hydraulic oil cooler, electric water pump, comprehensive radiator are communicated with, electric water pump drives circulating water and by cooling fan the comprehensive radiator high-temperature water is cooled off; Be communicated with absolutely empty intercooler by the hot air of pipeline after engine booster, cooling fan cools off hot air in the absolutely empty intercooler.Comprehensive radiator, water radiator from outside to inside successively stack weld together, and install side by side with absolutely empty intercooler one, can effectively solve poorly sealed, problem such as leak out between the radiator, improve the cooling system cooling effect, reduce spatial arrangement; Cooling fan is an air drafting type, and by motor driving, EDU unit controls rotation speed of the fan improves fan efficiency.Concrete structure is seen Fig. 1
The present technique invention efficiently solves: (1) a plurality of different cooling mediums cool off with a radiator; (2) different thermal source parts are cooled off separately, the operating temperature that has guaranteed them is in permission range separately; (3) realize that cooling fan can be according to temperature variation automatic speed regulation.
The hybrid power hydraulic excavator cooling system is simple, reliable, practical.
Description of drawings
Fig. 1 is hybrid power hydraulic excavator cooling system principle and connection diagram and hot-fluid flow direction schematic representation.
Embodiment
Referring to Fig. 1, engine water radiator, comprehensive radiator, the absolutely empty intercooler independent loops loop of respectively doing for oneself.Determine the boundary dimension and the fan size of radiator by the optimal design of it being carried out heat Balance Calculation, windage calculating, Wind Coverage Calculation and radiator inside.The engine water radiator carries the heat that produces when water pump is connected the back 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, forms the low temperature circulation loop; Be transported to absolutely empty intercooler by the hot air of pipeline after engine booster, cooling fan is taken away its heat then.Cooling fan is controlled its rotating speed by three road temperature parameters by EDU unit whole process, three road temperature parameters are respectively engine outlet water temperature, air-air intercooler cooling rear engine intake temperature, comprehensive radiator entering water temp, fan can be according to temperature variation automatic speed regulation (seeing Table 1), adopt relation in parallel between three temperature, promptly when reaching lower bound value of opening of expection setting, a temperature just begins to carry out " opening ", from " opening " to " standard-sized sheet " carries out linearly adjust, to the ceiling value standard-sized sheet.Have only when three tunnel temperature all are lower than " opening " temperature, carry out all " pass ".
Table 1 (temperature and control law)
| The temperature title | Open/℃ | The linearly adjust scope/℃ | Standard-sized sheet/℃ |
| Engine outlet water temperature | 80 | 80～90 | 90 |
| The comprehensive radiator entering water temp | 75 | 75～85 | 85 |
| Engine Inlet Temperature | 60 | 60～75 | 75 |
