Embodiment Construction

[0008] see figure 1 , The engine water radiator, integrated radiator, and air-to-air intercooler are each an independent circulation loop. The overall dimensions of the radiator and the size of the fan are determined by performing thermal balance calculation, wind resistance calculation, air volume calculation and the optimal design inside the radiator. The engine water radiator is connected with the engine's own water pump through the pipeline, and then the heat generated by the engine is taken away by the cooling fan to form a high-temperature circulation loop; the heat generated by the hydraulic oil is exchanged between the oil and water of the hydraulic oil cooler Transfer the heat to the integrated radiator, connect the hydraulic oil cooler, motor controller, generator, rotary motor, main pump motor, electric water pump, etc. It is taken away by the cooling fan to form a low-temperature circulation loop; the hot air after the engine is supercharged is sent to the air-to-...

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 [0001] The invention relates to a cooling system design of a hybrid excavator. Background technique [0002] At present, the cooling system used on excavators basically uses the engine's own water pump to cool the engine, and the cooling system of the hydraulic system uses air cooling, while the cooling system on the hybrid excavator uses high and low temperature circulating cooling: that is, the electric water pump circulates water to cool the hydraulic system and electrical appliances. Components and other low-temperature parts, the engine comes with a water pump to cool the engine. Contents of the invention [0003] Hybrid excavator is a new type of construction machinery developed on the basis of CN220 excavator chassis and traveling device technology to adapt to the application of national energy saving and emission reduction technology on excavators. The entire cooling system not only cools the engine, hydraulic system and engine boost air, but also ...
