Specific embodiment

To make the purpose of this utility model, technical scheme and advantage clearer, clear and definite, develop simultaneously implementation referring to the drawings Example is further described to the utility model.

Embodiment 1

Referring to Fig. 1, the utility model discloses a kind of effective double turbofan heat abstractors for reducing noise, wherein, bag Two blower fan fixed plates 2 of turbofan 1 and are included, two turbofans 1 are separately fixed at blower fan in the way of symmetrical reverse and consolidated It is above fixed board 2 and following.It can be seen that in Fig. 1, have on each turbofan 1 air outlet 5 and two in it is symmetrical, for installing Screw hole, during installation, two turbofans 1 are respectively symmetrically and are fixed on above blower fan fixed plate 2 and following, two turbines The air outlet 5 of blower fan is in rightabout, and as symmetrical reverse is installed.It is well known that the vibrations of blower fan are cause noise most main Want reason, therefore noise reduction is most direct, effective method is exactly to weaken vibrations, i.e., noise is reduced from sound source.When two turbine wind When machine 1 is installed in the way of symmetrical reverse, latter two turbofan 1 that is powered starts simultaneously, the vibrations that two turbofans 1 cause Propagated outward from the center of turbofan 1 simultaneously.In communication process, two vibrations of the co-propagate of turbofan 1 can phase mutual connection Touch and offset, therefore, the overall vibrations of blower fan apparatus can weaken significantly, and the noise of generation can also weaken significantly.Further, it is many Well known, sound wave is a kind of most common ripple, state when its amplitude, the direction of propagation and initial phase determine that ripple is propagated.When two When individual turbofan 1 is installed in the way of symmetrical reverse, noise amplitude that two turbofans 1 are produced is equal, initial phase is equal, But the direction of propagation is conversely, therefore, these noises major part when propagating can cancel each other, and further weaken noise.To sum up, when two When individual turbofan 1 is separately fixed above blower fan fixed plate 2 in the way of reverse symmetry and is following, can simultaneously from noise The sound source of generation and the aspect of approach two of noise transmission realize effective noise reduction.

In actual use, often require that during noise reduction and heat sinking function concentrated on into an equipment, make blower fan overall lighter Just.Therefore, it can add the teeth radiator 3 that radiating is connected, guided with blower fan fixed plate 2 in a device.The ring of teeth radiator 3 Shape is arranged in blower fan fixed plate 2, as depicted in figs. 1 and 2.By one block of aluminium of entirety, cut with the precision slicer of specialty Go out the radiating fin of normal pitch, that is, be made teeth radiator 3.As a result of accurate cutting technique, therefore, dissipated with general Backing is compared, and the thickness of the every a piece of radiating fin of teeth radiator 3 is substantially reduced.Manufactured as a result of aluminium integration, Therefore teeth radiator 3 is overall without thermal resistance, and heat transfer medium is stable, and radiating effect under equal conditions is traditional radiator 200%.Referring to Fig. 1, two air outlets of turbofan 15 are close to the fin of teeth radiator 3, two air outlets 2 respectively Air-out does not conflict mutually.When turbofan is operated, cold wind blows out under the guiding of the radiating fin of teeth radiator 3 toward two ends, Turbofan 1 and teeth radiator 3 heat of itself can in time be drained, and two air-out of blower fan do not conflict mutually, significantly Improve radiating efficiency.Meanwhile, teeth radiator 3 can also eliminate because air-flow propagate when friction and caused by noise, further Noise reduction.

In order to further strengthen the heat sinking function of double turbofan devices, it is allowed to meet the cooling requirements of industrial machine, can To increase the wind scooper 4 of guiding air-flow in a device.Referring to Fig. 3, embodiment 1 provides an efficient imaging lamp, and reduction is made an uproar Double turbofan devices of sound are arranged in machine, and wind scooper 4 is tapered, is arranged on outside teeth radiator 3, with other portions of machine Part is connected.

In actual production, double turbofan heat abstractors that the utility model is provided can be transformed into low-noise heat radiation dress Put, combined with other machines and installed and used, the efficient imaging lamp that such as embodiment 1 is provided.The efficient imaging lamp of specialty is used High-power COB（Chip On board) lamp bead.High-power COB lamp beads have brightness high, small volume, the low, long lifespan that consumes energy etc. excellent Point, but poor heat radiation and the noise problem of high-power radiator generation seriously limit the use matter of high-power COB lamp beads Amount and life-span, also counteracts that high-power COB lamp beads replace the process of typical high power bulb.The low of the utility model offer is provided Noise heat abstractor can then solve the above problems.First, first by two model identical turbofans 1 with the side of symmetrical reverse Formula is separately fixed above blower fan fixed plate 2 and following, used as a blower fan module.Whole blower fan module and teeth are dissipated again Hot device 3, wind scooper 4 are integrated into low-noise heat radiation device, it is actually used in can also add temperature in low-noise heat radiation device Sensor.Then the high-power COB lamp beads of efficient imaging lamp are fixed on low-noise heat radiation device, finally whole low noise Heat abstractor and high-power COB lamp beads are fixed on lamp body.Whole installation process facilitates simple and direct, it is only necessary to note each screw position Degree of agreement and ensure nut locking do not loosen.In embodiment 1 high-power COB lamp beads and teeth radiator 3 it Between coat the heat-conducting silicone grease of high-quality, when high-power COB lamp beads start-up operation adstante febre, conduction of the heat in the heat-conducting silicone grease of high-quality It is transmitted to teeth radiator 3 rapidly down.Teeth radiator 3 has high thermal conductivity, and the heat in lamp bead surface is extremely short The fin surface of teeth radiator 3 is spread in time, the heat of fin surface is taken away rapidly in the air-out of turbofan 1 again Amount, makes heat Quick diffusing in outside air.Since high-power COB lamp beads heat production, it is dispersed into air to heat, entirely Radiation processes are completed within the extremely short time, because of the accumulation of heat machine temperature will not be caused too high, influence high-power COB lamps The use quality of pearl and life-span.

Double turbofan heat abstractors that the utility model is provided, and the low-noise heat radiation device being transformed into by it, fit For the high or low power COB lamp beads of all different brands on the market.This low-noise heat radiation device volume is small, noise is small, radiating effect Rate is high, can efficiently solve the noise problem that poor heat radiation and high-power radiator are produced, therefore in many instances may be used Replace typical high power bulb with high-power COB lamp beads, substantially reduce the cost of production, improve the quality of light fixture.

The beneficial effects of the utility model：It is expensive without adding other to the blower fan of some using under specific condition Noise reducing apparatus, without complicated operating technology, you can reach the effect of noise reduction.Meanwhile, can change with reference to other thermal components Cause low-noise heat radiation device to use, on the premise of radiating effect is met, greatly reduce the noise that heat abstractor causes, it is whole Reduce industrial technical requirements and cost body.

It should be appreciated that application of the present utility model is not limited to above-mentioned citing, those of ordinary skill in the art are come Say, can according to the above description be improved or converted, all these modifications and variations should all belong to the appended power of the utility model The protection domain that profit is required.
