Description

A kind of silicon oil damper radiating fin
Technical field
The present invention relates to a kind of radiating fin, relate in particular to a kind of silicon oil damper radiating fin.
Background technique
Silicon oil damper is in a kind of being mainly used in, the damped type vibration damper of heavy-duty engine, and the torsional vibration energy of engine shaft being fastened through the silicone oil damping is converted into heat, realizes that engine shaft is the purpose of vibration damping.The heat that silicon oil damper produces must be dispersed in the surrounding atmosphere through the vibration damper shell, to avoid causing that the silicone oil temperature is too high.Because the too high meeting of silicone oil temperature causes the reduction of silicon oil viscosity; Cause the effectiveness in vibration suppression of vibration damper to descend; Can cause the bearing arrangement of silicon oil damper rotten when serious, engine shaft system is not had the effect of vibration damping with seal failure and silicone oil, even the aggravation engine shaft torsional oscillation that is.
At present; Solve the too high problem of silicon oil damper temperature; The most direct and effective method is exactly to increase radiating fin on the surface of silicon oil damper 1, and traditional heat radiating fin structure is made up of base plate of radiator 3 and fin 2, referring to Fig. 1, Fig. 2; Utilize fin 2 structures to increase the heat diffusion area of vibration damper, thereby reach the purpose that improves silicon oil damper 1 heat dissipation potential.In manufacture process, utilize the mode of welding that base plate of radiator 3 is connected on the silicon oil damper 1; The heat of silicon oil damper 1 generation is passed on the base plate of radiator 3 by the housing of vibration damper in the course of the work; Be delivered on the fin 2 by base plate of radiator 3 again; Be dispersed in the air through fin 2 at last, realize heat radiation.This structure heat transfer path is longer; Thermal resistance is bigger; In the process that vibration damper is made, base plate of radiator 3 is welded on the silicon oil damper 1 through weld seam 4, and the zone of base plate of radiator 3 except that weld seam 4 can not well contact; Heat passes to fin 2 from silicon oil damper 1 need overcome very big thermal resistance, has weakened radiating effect.
Like Chinese utility model patent notification number: CN201517584U; Open day: the utility model patent on June 30th, 2010 disclosed a kind of vibration damper radiating fin, comprises heat sink body, and described heat sink body ringwise; Alternate with grooved hole on heat sink body; Be provided with heat sink body along the slotted eye lengthwise edge be connected as a single entity, fin that direction is consistent since on heat sink body towards grooved hole, be provided with heat sink body along the slotted eye lengthwise edge be connected as a single entity, fin that direction is consistent; Good heat dissipation effect is fixed on the silicon oil damper this radiating fin to improve the effectiveness in vibration suppression of silicon oil damper.But the fin processed complex of this device, heat diffusion area is still less, and the heat transfer path is longer, and thermal resistance is bigger, and radiating effect is not good.
Summary of the invention
It is not good to the objective of the invention is to be directed against existing silicon oil damper radiating effect, and the heat transfer path is longer, and defective that thermal resistance is bigger and deficiency provide a kind of heat transfer path shorter, and thermal resistance is less, the better a kind of silicon oil damper radiating fin of radiating effect.
For realizing above-mentioned purpose; Technical solution of the present invention is: a kind of silicon oil damper radiating fin; The arranged outside of said silicon oil damper has the radiating fin outrigger; The inboard of silicon oil damper is provided with the radiating fin medial cradle, is provided with radiating fin ringwise between radiating fin outrigger and the radiating fin medial cradle.
Said radiating fin outrigger and radiating fin medial cradle are weldingly fixed on through weld seam with the outside of silicon oil damper.
Distance between said radiating fin and the silicon oil damper is greater than 2 millimeters.
The ratio of area of contact between said radiating fin and the silicon oil damper and radiating fin frontal area on silicon oil damper is smaller or equal to 1:2.
The invention has the beneficial effects as follows:
1. the present invention has radiating fin in the arranged outside of silicon oil damper; Radiating fin outrigger and radiating fin medial cradle are weldingly fixed on through weld seam with the outside of silicon oil damper; Be provided with blade ringwise on radiating fin outrigger and the radiating fin medial cradle; Between blade and the shock absorber casing certain distance is arranged, increased the heat dissipation potential of vibration damper.
2. the present invention is simple in structure; Utilize the rotation of engine shaft system to change silicone oil shock absorber shell flow field on every side; Accelerate the flowing velocity of silicone oil shock absorber shell surrounding atmosphere, further strengthened the heat dissipation potential of silicon oil damper, helped improving the damping property of silicon oil damper.

Among the figure: silicon oil damper 1, fin 2, base plate of radiator 3, weld seam 4, radiating fin 5, radiating fin outrigger 6, radiating fin medial cradle 7.
Embodiment
Below in conjunction with description of drawings and embodiment the present invention is made further detailed description.
Referring to Fig. 3, Fig. 4; A kind of silicon oil damper radiating fin of the present invention; Comprise silicon oil damper 1; The arranged outside of said silicon oil damper 1 has radiating fin outrigger 6, and the inboard of silicon oil damper 1 is provided with radiating fin medial cradle 7, is provided with radiating fin 5 ringwise between radiating fin outrigger 6 and the radiating fin medial cradle 7.
Said radiating fin outrigger 6 is weldingly fixed on through weld seam 4 with the outside of radiating fin medial cradle 7 with silicon oil damper 1.
Distance between said radiating fin 5 and the silicon oil damper 1 is greater than 2 millimeters.
The ratio of the area of contact between said radiating fin 5 and the silicon oil damper 1 and radiating fin 5 frontal area on silicon oil damper 1 is smaller or equal to 1:2.
The arranged outside of silicon oil damper 1 has radiating fin outrigger 6; The inboard of silicon oil damper 1 is provided with radiating fin medial cradle 7; Radiating fin outrigger 6 is used for installing and fixing radiating fin 5 with radiating fin medial cradle 7, and silicon oil damper 1 is weldingly fixed on through weld seam 4 between radiating fin outrigger 6 and radiating fin medial cradle 7.The ratio of stating area of contact and radiating fin 5 frontal area on silicon oil damper 1 between radiating fin 5 and the silicon oil damper 1 is smaller or equal to 1:2.Be provided with radiating fin 5 ringwise between radiating fin outrigger 6 and the radiating fin medial cradle 7, increased the area of contact of radiating fin 5 and peripheral air, thereby the heat that silicon oil damper 1 is produced sooner, more effectively take away.Blade structure through radiating fin 5 changes silicon oil damper 1 housing flow field on every side, improves the surperficial air velocity of silicon oil damper 1 housing.
The present invention utilizes silicon oil damper 1 to be installed in the characteristics on the engine revolution parts, has cancelled traditional base plate of radiator 3, adopts and the less supporting structure of silicon oil damper 1 housing area of contact, and promptly the radiating fin outrigger 6.Radiating fin 5 is welded between radiating fin outrigger 6 and the radiating fin medial cradle 7 or whole machine shaping; Distance between radiating fin 5 and the silicon oil damper 1 is greater than 2 millimeters; Make between radiating fin 5 and the radiating fin outrigger 6 to not exclusively to contact; Form continuous space, help reducing thermal resistance, improve radiating efficiency.Utilize simultaneously the rotation of engine shaft system to change silicon oil damper 1 housing flow field on every side in the course of the work, accelerated the flowing velocity of silicon oil damper 1 housing surrounding atmosphere, further strengthened the heat dissipation potential of silicon oil damper.
