Abstract
The utility model is provided in one kind, large excavator fuel oil radiator structure, including fuel oil radiator, it is characterised in that described fuel oil radiator is arranged on the side wall of the engine bin on the outside of heat radiator assembly wind scooper.The utility model is flowed through the characteristic flowed after wind scooper perpendicular to engine axis direction using air and cools down fuel oil, both the air themperature for having prevented the air intake resistance caused by Fuel Oil Cooler is arranged in radiator front end to increase and flow through heat radiator assembly rises, the radiating efficiency of heat radiator assembly is improved, also ensure that Fuel Oil Cooler there are enough air mass flows to cool down fuel oil.
Description
Technical field
The utility model is related in one kind, large excavator fuel oil radiator structure, belongs to excavator fuel oil radiator peace
Fill technical field.
Background technology
With the implementation of the mechanical stage emission regulation of state three of non-rice habitats, field is manufactured in excavator, fuel oil temperature is reasonable
Limit value the following is the premise that engine fuel oil system normal work, engine power are normally played is ensured, fuel oil temperature exceedes
Limit value, fuel oil is expanded with heat and contract with cold, and the unit volume fuel oil quality of injection pump of engine injection is reduced, and the heat that burning is produced accordingly subtracts
Few, engine power output reduction even makes plant equipment can not normal work when serious.And engine oil return temperature is generally inclined
Height, to prevent oil return from causing the temperature rise of fuel tank internal fuel too high, it is necessary to reduce returning-oil temperature using fuel oil radiator.
At present, the engine blower of excavator is all air draught mode, and cold air is after heat radiator assembly, then process is started
Cabin, from exhaust outlet discharge；In majority, big excavator fuel oil radiator arrangement installed using series system, in heat radiator assembly
Front side, perpendicular to engine axis arrangement, the air that fan belt comes can be directly by radiator core body, but arrangement meeting shadow above
Heat radiator assembly radiating effect is rung, cold air becomes hot-air after fuel oil radiator, then passes through what is taken away during heat radiator assembly
Heat will be reduced substantially, larger on excavator cooling liquid radiator or hydraulic oil radiator influence, meanwhile, air drag also can
Increase, influences air mass flow, further influence radiating.
On radiator wind-guiding cover air outlet periphery, not all air is through row along the directly flowing of engine axis direction
Air port is discharged, but it is most of test approximately perpendicular to axis direction flowing, impact after the dividing plate of engine bin again along starting
Machine axis direction is discharged through exhaust outlet.
The content of the invention
It is to be solved in the utility model be to provide in one kind, large excavator fuel oil radiator structure, to ensure fuel oil
The radiating efficiency of radiator, while improving the radiating efficiency of heat radiator assembly, it is ensured that fuel oil temperature, coolant temperature or hydraulic oil
Temperature etc. all works in the reasonable scope.
In order to solve the above problems, the utility model is provided in one kind, large excavator fuel oil radiator structure, including
Fuel oil radiator, it is characterised in that described fuel oil radiator is arranged at the engine bin on the outside of heat radiator assembly wind scooper
On the wall of side.
Further, described fuel oil radiator is arranged parallel to the axis of engine.
Further, it is provided with described engine bin on the upside of engine, engine and is provided with fan drive device, fan drives
Heat radiator assembly is provided with the upside of dynamic device connection fan, fan.
Further, the side wall of described engine bin is provided with engine bin dividing plate, and fuel oil radiator, which is arranged at, to be started
On cabin dividing plate.
Compared with prior art, the beneficial effects of the utility model are：
The utility model is flowed through the characteristic flowed after wind scooper perpendicular to engine axis direction using air and cools down combustion
Oil, had both prevented the air intake resistance caused by Fuel Oil Cooler is arranged in radiator front end to increase and flow through the sky of heat radiator assembly
Temperature degree rises, and improves the radiating efficiency of heat radiator assembly, also ensure that Fuel Oil Cooler has enough air mass flows cold
But fuel oil.
Brief description of the drawings
Fig. 1 be in, large excavator fuel oil radiator structure schematic diagram.
Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation scope of the present utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
Embodiment
As shown in figure 1, in one kind, large excavator fuel oil radiator structure, including fuel oil in engine bin dissipates
Engine 6 is provided with hot device 5, described engine bin, the upside of engine 6 is provided with fan drive device 3, fan drive device 3
Fan 2 is connected, the upside of fan 2 is provided with heat radiator assembly 1.Described fuel oil radiator 5 is arranged at outside heat radiator assembly wind scooper
On the side wall of the engine bin of side.Described fuel oil radiator 5 is arranged parallel to the axis of engine 6.
The side wall of described engine bin is provided with engine bin dividing plate 4, and fuel oil radiator 5 is arranged at engine bin dividing plate
On 4.On heat radiator assembly wind scooper air outlet periphery, air flow as shown in figure 1, most of air is approximately perpendicular to axis side
To flowing, impact the axis direction after engine bin dividing plate 4 again along engine 6 and discharged through exhaust outlet.The cloth of fuel oil radiator 5
Put near the wind scooper of heat radiator assembly 1, arrange that air is flowed through after wind scooper, blown to parallel to the axis direction of engine 6
On the air channel of fuel oil radiator 5, take away after the heat dissipated needed for fuel oil and to be reflected through engine bin dividing plate 4, along the axle of engine 6
Flow out engine bin in line direction.Both the air intake resistance caused by fuel oil radiator 5 is arranged in the front end of heat radiator assembly 1 had been reduced to add
Air themperature that is big and flowing through heat radiator assembly 1 rises, and improves the radiating efficiency of heat radiator assembly 1, also ensure that fuel oil dissipates
Hot device 5 has enough air mass flows to cool down fuel oil, fuel oil temperature is reduced to zone of reasonableness.
