Abstract
The utility model discloses a novel excavator cooling system which comprises a main radiator (2) and a hydraulic oil radiator (3). The main radiator (2) is connected with an engine (1), a main fan of the main radiator (2) is directly driven by the engine (1), and the hydraulic oil radiator (3) comprises an auxiliary fan (31) driven by a hydraulic motor. The novel excavator cooling system is divided into two radiators, the two fans are used, the diameters of the fans are reduced, arrangement of the whole device is facilitated, and noise is also reduced. The rotating speed of the auxiliary fan (31) varies according to the temperature of hydraulic oil without being influenced by rotating speed of the engine (1), the hydraulic oil is accurately cooled, and necessary loss is reduced.
Description
Technical field
The utility model belongs to the technical field of engineering machinery, relates in particular to a kind of dredger radiation system.
Background technique
Existing radiator heat-dissipation form, motor directly drives a fan, and a synthetic integrated radiator (comprising cold in absolutely empty, water-cooled, hydraulic pressure oil cooling) is cooled off.When low-powered engine was dispelled the heat, the space of radiator and wind-exposuring area can be tackled the heat radiation needs, but before high power engine, because complete machine arranges that radiator and fan can't be accomplished so large, cause radiating effect not good enough.And rotation speed of the fan determines that according to engine speed for the cooling of hydraulic oil, can't accomplish that follow-up changes in good time, energy consumption is larger.
The model utility content
The defective poor for traditional excavator radiation system radiating effect, that energy consumption is large, technical problem to be solved in the utility model provide a kind of good heat dissipation effect, can regulate according to the hydraulic oil oil temperature dredger radiation system of rotation speed of the fan.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of dredger radiation system, comprise main radiator and hydraulic oil cold heat sink, described main radiator is connected with motor, and the main fan of described main radiator is directly driven by motor; Described hydraulic oil cold heat sink comprises secondary fan, gear pump and oil hydraulic motor, and described gear pump is connected with motor, and the oil outlet of described gear pump is connected with the filler opening of oil hydraulic motor, and the pto＝power take-off of described oil hydraulic motor is connected with secondary fan.
Described main radiator comprises absolutely empty ICS intercooler system and constituent.
The utility model has the advantage of that two radiators are arranged side by side, and have increased wind-exposuring area, have improved greatly radiating effect.After being dispersed into two radiators, use two fans, reduced fan diameter, made things convenient for complete machine to arrange and also reduced noise.The rotation speed of the fan of hydraulic pressure oil cooling changes according to the height of hydraulic oil temperature, affected by engine speed, dispels the heat for hydraulic oil more accurately, has reduced unnecessary loss.

Mark among the above-mentioned figure is: 1, motor, 2, main radiator, 3, the hydraulic oil cold heat sink, 31, secondary fan.
Embodiment
Fig. 1～Fig. 4 is the structural representation of a kind of dredger radiation system of the utility model, comprises main radiator 2 and hydraulic oil cold heat sink 3, and main radiator 2 is connected with motor 1, and the main fan of main radiator 2 is directly driven by motor 1; Hydraulic oil cold heat sink 3 comprises secondary fan 31, gear pump and oil hydraulic motor, and gear pump is connected with motor 1, and the oil outlet of gear pump is connected with the filler opening of oil hydraulic motor, and the pto＝power take-off of oil hydraulic motor is connected with secondary fan 31.
Main radiator 2 comprises absolutely empty ICS intercooler system and constituent.The hydraulic pressure oil cooling is separated, made two radiators, adopt two fans to cool off.Main radiator 2 is cold synthetic with water-cooled in absolutely empty, and the main fan that is directly driven by motor 1 cools off.The hydraulic oil cold heat sink is the hydraulic pressure oil cooling, drives a gear pump band hydrodynamic pressure motor by motor 1 power taking mouth, the secondary fan 31 of fluid motor-driven, and secondary fan 31 rotating speeds just change according to hydraulic oil temperature.
After adopting such structure, two radiators are arranged side by side, and have increased wind-exposuring area, have improved greatly radiating effect.After being dispersed into two radiators, use two fans, reduced fan diameter, made things convenient for complete machine to arrange and also reduced noise.The rotation speed of the fan of hydraulic pressure oil cooling changes according to the height of hydraulic oil temperature, no longer is subjected to motor 1 influence of rotation speed, dispels the heat for hydraulic oil more accurately, has reduced unnecessary loss.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out; or without improving design of the present utility model and technological scheme are directly applied to other occasion, all within protection domain of the present utility model.
Claims (2)
1. a dredger radiation system is characterized in that, comprises main radiator (2) and hydraulic oil cold heat sink (3), and described main radiator (2) is connected with motor (1), and the main fan of described main radiator (2) is directly driven by motor (1); Described hydraulic oil cold heat sink (3) comprises secondary fan (31), gear pump and oil hydraulic motor, described gear pump is connected with motor (1), the oil outlet of described gear pump is connected with the filler opening of oil hydraulic motor, and the pto＝power take-off of described oil hydraulic motor is connected with secondary fan (31).
