Abstract
The utility model provides an engineering machine multi-fan heat radiation device which comprises a plurality of heat radiation modules. When the temperature of a certain heat radiation module is overhigh, a corresponding temperature sensor transmits a temperature signal to a controller. After the controller performs comparison and analysis, the controller transmits instruction current to a corresponding adjusting device for increasing the rotation speed of a cooling fan which corresponds to the heat radiation module. When the temperature of the heat radiation module is in an optimal temperature range and no cooling is required, the corresponding temperature sensor transmits the temperature signal to the controller. The controller transmits the instruction current to the corresponding adjusting device for stopping rotation of the corresponding cooling fan. Thus each heat radiation module can perform targeted cooling according to a respective target cooling temperature, so that each module is in the respective optimal operation temperature range. Furthermore, when some cooling modules do not require cooling, rotation of the corresponding cooling fans can be stopped, thereby effectively preventing engine power wastage and reducing emission of the engine.
Description
Technical field:
The present invention relates to a kind of radiator fan device in a kind of struction machine structures field.Carry out specific aim by each radiating module of dispersed placement according to target chilling temperature separately cooling, make each radiating module respectively in best thermal equilibrium state, better heat-radiation effect, can save engine power consumption, reduces discharge simultaneously.
Background technique:
Engineering machinery is the machinery that integrates heating source and source of heat release, and its thermal equilibrium surpasses or do not reach thermal equilibrium temperature scope (being overheated or excessively cold), all can have a negative impact to engineering machinery reliability of operation, the feature of environmental protection and efficiency etc.Theory and practice shows, when heating and heat radiation reach optimum balance, can make the running state of engineering machinery in efficient, energy-conservation and environmental protection.The optimal heat balance parameters of part engineering machinery is as follows: 75～95 ℃ of diesel engine water temperatures, 55～75 ℃ of hydraulic oil temperatures, 85～90 ℃ of torque-converters oil temperatures, 55～75 ℃ of machine oil oil temperatures.
Traditional engineering mechanical radiating system is comprised of a plurality of radiating modules, take bulldozer as example, it comprise water-cooled module, hydraulic oil radiating module, torque-converters oil radiating module, absolutely empty in cold radiating module etc. successively serial or parallel connection become one group, be arranged on same cooling fan front end.A plurality of heat spreader module serial or parallel connections together, the flow resistance that makes cooling-air pass through each radiator increases, and the accumulation of heat effect is arranged, and has dwindled the temperature difference of cooling liquid in cool air and radiator, reduced radiating effect, and the coupling more complicated of fan and radiator.Due to a plurality of radiators, to share a desk fan cooling, thereby it is cooling to carry out by target chilling temperature separately specific aim.As long as a module excess Temperature is arranged like this, cooling fan will start, and not need cooling module also to be forced to cooling, so just can't make each radiating module all in best thermal equilibrium state, and cause the waste of engine power, increase discharge.
Summary of the invention:
The purpose of this utility model is: overcome the deficiencies in the prior art, a kind of engineering machinery multi-fan sink is provided, adopt the engineering machinery of this sink, can make each radiating module respectively in best thermal equilibrium state, better heat-radiation effect, can save engine power consumption, reduce discharge simultaneously.
Engineering machinery multi-fan sink comprises a plurality of radiating modules, each radiating module adopts separately an independently cooling fan, each independently cooling fan cross scale by one and directly be connected with oil hydraulic motor, the fluid motor-driven cooling fan, fan guard is bolted on radiating module.
Further, also comprise temperature transducer, controller and controlling device.
Multi-fan sink described in the utility model, comprise a plurality of radiating modules, when a certain radiating module excess Temperature, corresponding temperature transducer passes to controller by temperature signal, send instruction current after the controller comparative analysis to corresponding controlling device, the cooling fan rotation speed that this radiating module is corresponding is increased; And when the temperature of this radiating module in optimum temperature range, do not need when cooling, corresponding temperature transducer passes to controller by temperature signal, controller sends instruction current to corresponding controlling device, and its corresponding cooling fan is stopped operating.It is cooling that each radiating module just can carry out according to target chilling temperature separately specific aim like this, makes each module all in optimum working temperature scope separately.And, when the radiating module had does not need when cooling, corresponding cooling fan just can stop operating, and has effectively avoided the waste of engine power, has reduced the motor discharge.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
1-radiating module I, 2-cooling fan I, 3-radiating module II, 4-cooling fan II, 5-radiating module III, 6-cooling fan III, 7-radiating module IV, 8-cooling fan IV, 9-bolt, 10-fan guard 11 in figure-mistake scale 12-oil hydraulic motor
Embodiment:
The multi-fan sink the utility model proposes, its each radiating module adopts separately an independently cooling fan, and each fan is driven by oil hydraulic motor separately.The bulldozer of take describes in detail as embodiment, its embodiment as shown in Figure 1, radiating module I (1) is water radiator, and radiating module II (3) is hydraulic oil radiator, and radiating module III (5) is that torque-converters oil radiator, radiating module IV (7) are absolutely empty middle cold heat sink.Wherein, the cooling fan I (2) of water radiator is crossed scale (11) by one and directly is connected with oil hydraulic motor (12), and fan guard (10) is fixed on water radiator by bolt (9).Identical with hydraulic oil radiator, torque-converters oil radiator, the absolutely empty middle cold heat sink cooling fan I (2) that mounting type and the water radiator of corresponding cooling fan II (4), cooling fan III (6), cooling fan IV (8) is corresponding respectively.
In the bulldozer working procedure, during the water radiator excess Temperature, corresponding temperature transducer passes to controller by temperature signal, sends instruction current after the controller comparative analysis to corresponding controlling device, and cooling fan I (2) rotating speed is increased; And when the temperature of water radiator in optimum temperature range, do not need when cooling, corresponding temperature transducer passes to controller by temperature signal, controller sends instruction current to corresponding controlling device, and cooling fan I (2) is stopped operating.In like manner, when the operating temperature of hydraulic oil radiator, torque-converters oil radiator, absolutely empty middle cold heat sink changes, corresponding cooling fan II (4), cooling fan III (6), cooling fan IV (8) also can be regulated rotating speed separately automatically according to said process.Like this, the optimum working temperature that water radiator, hydraulic oil radiator, torque-converters oil radiator, absolutely empty middle cold heat sink just can be take separately is target, carries out specific aim cooling, makes each radiating module all in optimum working temperature separately.And when certain radiator does not need when cooling, corresponding cooling fan just can stop operating, and can effectively avoid the waste of engine power, reduces motor and discharges.
