Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated. Should be understood that,Detailed description of the invention described herein only, for description and interpretation the present invention, is not limited to thisBright.
In the present invention, in the situation that not doing contrary explanation, the noun of locality of use as " upper and lower, top,The end " normally for direction shown in the drawings or for vertically, on vertical or gravity directionThe relationship description word of each parts mutual alignment. " width " of radiator refers in accompanying drawingThe horizontal direction of radiator, be also the horizontal side of the vehicle chassis of radiator while being arranged on vehicle conventionallyTo.
As shown in Figures 3 to 5, the invention provides a kind of engine radiator, this engine radiatorComprise upper tank 1, radiating tube 2 and lower header 3. Wherein, water inlet 4 and the Xia Shui on upper tank 1Delivery port 8 on chamber 3 is all positioned at the same side of the broad ways of engine radiator, in lower header 3Comprise upper chamber 31 and lower chamber 32 that in the vertical direction separates, this lower chamber 32 along send outBetween one side of the width of motivation radiator and upper chamber 31, there is the runner of connection, and under thisThe opposite side of the width along engine radiator of portion's chamber 32 is provided with delivery port 8, this delivery port8 are communicated with lower chamber 32 and upper chamber 31 is communicated with radiating tube 2. As total design, owing to sending outWhat the common broad ways of motivation radiator was arranged on vehicle chassis (is transversely the thickness direction of radiatorRoughly the same with the fore-and-aft direction of vehicle, the length direction of radiator is arranged along vehicle-height direction), because ofAnd be arranged in homonymy according to the water inlet 4 in engine radiator of the present invention and delivery port 8, installingCan be arranged in respect to vehicle chassis with engine intake-outlet and engine water pump on vehicle timeThe homonymy of longitudinal centre line, thus no longer need to cross over longitudinal centre line long, more greatly and on chassisHeavy pipeline 11 and fitting attachments thereof, as support 10 etc., have alleviated construction weight, have optimized mounting structure.In optimizing mounting structure, for avoiding the pressure of the cooling fluid in engine radiator as shown in Figure 2The problems such as power, flow velocity inequality, radiating effect are clear, the present invention by dividing in the lower header 3 of radiatorBe separated out upper chamber 31 and lower chamber 32, connection runner and delivery port 8 between the two are arranged on edgeThe both sides of the width of radiator. Like this, cooling fluid flows into upper tank 1 from water inlet 4, through looseAfter heat pipe 2 heat radiations, flow into the upper chamber 31 of lower header 3 by the bottom end opening 6 of radiating tube, on topAfter flowing along the width of radiator in chamber 31, the connection runner from a side of width flow to againLower chamber 32, the delivery port 8 of the last opposite side from radiator width flows out. Like this, from upperThe cooling fluid flowing down via the radiating tube 2 of diverse location in hydroecium 1 gathers arrival and is communicated with runner, then from connectingPassage flow duct flows through lower chamber 3, altogether after roughly the same main-process stream, flows out from delivery port 8, fromAnd making cooling fluid flow equalization in radiator, hydraulic pressure and flow velocity also can be comparatively stable. Cooling fluid is looseFlow path in hot device is long, and radiating effect is also just better.
In order to be separated out upper chamber 31 and lower chamber 32 in lower header 3, in present embodiment, adoptBe used in the interior mode that inner chamber dividing plate 7 is set of lower header 3 of engine radiator. As shown in Figure 4, this is interiorThe width that chamber dividing plate 7 is preferably on the width along engine radiator is less than the wide of lower header 3Degree, like this, inner chamber dividing plate 7 can be arranged so that lower header 3 is at the width along engine radiatorA side be formed with and do not separated by inner chamber dividing plate 7 and as being communicated with the connection chamber 33 of runner. As front instituteState, connection runner and delivery port 8 are arranged in the both sides of the width of radiator, thereby near water inletThe cooling fluid flowing out in 4 radiating tube 2 need to flow to flowing as being communicated with of opposite side through upper chamber 31The connection chamber 33 in road, flows back into the delivery port 8 of the same side and flows out through this connection chamber 33. As figureShown in 5, by above-mentioned inner chamber dividing plate 7 is set, can solve the loose of the close water inlet 4 shown in Fig. 2The cooling fluid flowing out in heat pipe 2 copies compared to the cooling fluid in other radiating tube the problem that " shortcut " flows out.Make the cooling fluid flowing out from each radiating tube 2 flow into from water inlet 4 process that delivery port 8 flows outIn the main-process stream that flows through roughly quite (as shown by the arrows in Figure 5, this main-process stream is roughly the height of radiatorDegree is added double-width), thus make coolant flow equilibrium, stable.
Wherein, on the width along engine radiator, the width of inner chamber dividing plate 7 is preferably not littleIn 80% of the width of lower header 3. The width of inner chamber dividing plate 7 is too small, inner chamber as shown in Figure 5 everyThe cooling fluid that the corresponding top of the end radiating tube 2 near being communicated with chamber 33 of plate 7 flows down obtainsShortcut, its main-process stream in radiator is as above with regard to being significantly less than, and " height of radiator is addedDouble-width " main-process stream, do not flow uneven, flow velocity and pressure not etc. thereby cause. If inner chamber dividing plate 7Width excessive, the sectional area that is communicated with chamber 33 is too small, cause cooling fluid flowing through be communicated with chamber 33Time pressure and flow velocity increase, cause that current are congested, whirlpool etc. Be comparative optimization upper chamber 31,The cross-sectional area of lower chamber 32 and connection chamber 33 is all equal, and inner chamber dividing plate 7 is arranged on lower headerCentral region vertically in 3, mobility is better. Inner chamber dividing plate 7 also can have other shape,Structure and mounting means, for example inner chamber dividing plate 7 and lower header 3 are at the width along engine radiatorOn width identical, in other words, inner chamber dividing plate 7 is along whole this lower header that separates of width of radiator3. And as shown in Fig. 4 or Fig. 5, on the left side of inner chamber dividing plate 7, be provided as above-mentioned connection runnerOpening, cooling fluid can flow into lower chamber 32 via this opening from upper chamber 31, wherein as connectingThe opening of passage flow duct and delivery port 8 lay respectively at the both sides of the width of radiator, and this opening can beVarious shapes are as circular, square etc., and its cross-sectional area also can be preferably and upper chamber 31 as described aboveIdentical with the cross-sectional area of lower chamber 32. In addition, the volume of lower header 3 is preferably more than upper tank 1Volume, be separated out after upper chamber 31 and lower chamber 32 at lower header 3 making, cooling fluid is dividedThe flow velocity in upper tank 1, upper chamber 31 and lower chamber 32 can not keep approaching consistent. RelativelyPreferably lower header 3 volumes are the twice of the volume of upper tank 1, and inner chamber dividing plate 7 is arranged on lower headerCentre vertically in 3, the volume of upper tank 1, upper chamber 31 and lower chamber 32Almost identical, thereby flow velocity is also just almost constant.
In addition,, height higher at cooling liquid speed or radiating tube 2 is large, add inner chamberDividing plate 7 is preferably and is horizontally disposed with, and cooling fluid is because high flow rate adds that self gravitation effect is from radiating tubeWhen bottom end opening 6 flows to the upper surface of inner chamber dividing plate 7, its impulsive force is larger, especially coolant rateWhen large, total impulsive force is larger, not only easily damages inner chamber dividing plate 7 and mounting structure thereof, to cooling fluidSteady flow also impacts, and impacts the excessive flow disturbance that causes. Therefore, in present embodiment at inner chamberOn the upper surface of dividing plate 7, be formed with the slope 71 towards the bottom end opening 6 of radiating tube 2. Like this, coldBut liquid falls to after slope 71, not only can change the flow direction, slow down, reduces impact forces, also canAvoid flow disturbance. Inner chamber dividing plate 7 can process above-mentioned slope 71 in advance, then by sides such as weldingFormula is installed in lower header 3. Inner chamber dividing plate 7 can be also dull and stereotyped, realizes tiltedly by installing deflector 9 additionalDomatic refluence. Like this, deflector 9 is arranged on inner chamber dividing plate 7 towards the bottom end opening 6 of radiating tube 2And with respect to the setting that is inclined upwardly of this inner chamber dividing plate 7. The oblique angle of slope 71 or deflector 9 are relativeCan be preferably 30 ° to 75 ° in the acclivitous angle of inner chamber dividing plate 7, tie again to reach water conservancy diversion effectStructure is stable, occupies little space.
