Abstract
The invention discloses an engine radiating and wind guiding system for high-power machinery, belonging to an auxiliary engine radiating device. The system comprises an independent wind suction type radiating system, and a wind deflector is arranged between a radiator and an engine compartment of the radiating system, wherein the radiator consists of a hydraulic oil tank and a wind suction fan; a pipeline runs through between the engine compartment and the hydraulic oil tank and is internally provided with cooling medium; a pore is arranged on the wind deflector; a round table-shaped wind scooper is fixed in the center on the wind suction fan, and the top of the wind scooper is provided with a pore which is on the same straight line with the pore of the wind deflector. Through the transition of the engine radiating and wind guiding system for high-power machinery, the air exhaust of the radiating system is smoother, and wind suction radiation in the radiating system is changed into a dual radiating mode of cooling medium circulating and wind suction cooling so as to ensure that the radiating efficiency of the independent hydraulic engine wind suction type radiating system is obviously improved and more beneficial to the use of the engine radiation of high-power engineering machinery.
Description
Technical field
The present invention relates to the motor auxiliary radiating device, a kind of engine radiating and wind guiding system for high-power machinery of saying so more specifically.
Background technique
The loader radiation system plays considerable effect in the engine operation process of large-scale engineering machineries such as loader, grader, and existing radiation system mostly is and uses motor to carry fan, adopts blowing type to motor and the ducted cooling medium cooling of engine radiating.Sharply abominable along with the further needs in market and operating ambient temperature, especially export the loader in African market, heat dissipation potential to the loader motor has proposed requirements at the higher level, blower fan need adopt hydraulic pressure transmitter drive, radiating mode changes air drafting type into when also needing by blowing, promptly adopt blower fan that the heat that is produced in the motor is taken away, just need wind-guiding device guiding blower fan thus the heat of being extracted out is discharged outside the hood.
At present, more domestic manufacturers have adopted fluid power motor independently to drive and the air drafting type heat radiation in radiation system, but special wind-guiding device is not arranged, still the barge board of continuing to use between former radiator and the motor carries out wind-guiding, but the heat that can not effectively blower fan be discharged is like this discharged outside the hood, also can cause air turbulence between radiation system and the motor, air draft is not smooth, influence radiating effect, make the independent hydraulically controlled motor air drafting type radiation system of employing can not really give play to due effect.
Summary of the invention
The objective of the invention is to solve above-mentioned deficiency, a kind of engine radiating and wind guiding system that is specifically designed to high-power machinery is provided.
For solving above-mentioned technical problem, the present invention by the following technical solutions:
Engine radiating and wind guiding system for high-power machinery of the present invention, comprise independently air drafting type radiation system, be provided with barge board between radiator in the radiation system and the engine nacelle, wherein radiator is made up of hydraulic oil container and blower fan, be through with pipeline between engine nacelle and the hydraulic oil container, cooling medium is arranged in the pipeline, cooling medium absorbs in engine nacelle by pipeline and enters hydraulic oil container behind the heat and enter in the engine nacelle with pipeline after by blower fan air draught cooling again, circulate with this, described barge board is provided with perforate, the center is fixed with the frustoconic shape wind scooper on the described blower fan, the wind scooper top also is provided with a perforate, and with barge board on perforate on same straight line.
Further technological scheme is: described frustoconic shape wind scooper is by being bolted to the blower fan center, and with the central axis of blower fan on same straight line.
Further technological scheme is: described frustoconic shape wind scooper is by a ring plate and a sector welding fabrication.
Cooling medium circulates between hydraulic oil container and engine nacelle with pipeline, during through hydraulic oil container, under the air draught effect of blower fan, reduce the temperature of cooling medium, cooling medium enters engine nacelle via pipeline more then, circulate with this, simultaneously because wind scooper integral body is frustoconic shape, the derivation hood of the hot air smoothness that blower fan can be taken out of from hydraulic oil container, and wind scooper is installed in blower fan central axis place, and the wind scooper both sides have outside high velocity air again, the inner meeting of wind scooper this moment forms negative pressure, and air-flow can flow to the direction opposite with wind scooper both sides air-flow, and then discharges from the barge board tapping by the hot air that is produced in the guiding of the perforate on the barge board engine nacelle, via the perforate at wind scooper top, discharge hood with the air-flow on wind scooper both sides at last again.
Compared with prior art, the invention has the beneficial effects as follows: the hot air that both blower fan can have been discharged is derived hood, also the part heat in the engine nacelle effectively can be discharged hood, cost is lower, easy to process, install simply lightly, can directly be fixed on the axle center of blower fan in the radiator by bolt, more make full use of the space, do not influence the installation and the use of the self-contained engine of blower fan; By engine radiating and wind guiding system for high-power machinery of the present invention excessively, make the radiation system air draft more smooth and easy, thus the heat radiation of the air draught in the radiation system is become the dual radiating mode of circulating cooling medium and air draught cooling, the radiating efficiency of independent hydraulically controlled motor air drafting type radiation system is significantly improved, help high-power engineering machinery more, especially use on the large-duty loader of under rugged environment, working.
