Background technology
Along with human society is constantly progressive, process of urbanization is constantly accelerated, and resource consumption is in continuous growth, and has become and influence the key factor that Community health develops, and the demand of the new technology of various raising energy efficiencies is more and more urgent.At lighting field, the technological progress under this background of LED semiconductor lighting gets very fast, and application scale is increasing.In the technical barrier that current LED illuminating product is faced; Heat dissipation problem is the greatest problem that the LED light fixture faces, and radiator material, efficiently radiates heat area, metal substrate, encapsulation packing material, concurrent condition, radiation are the principal elements that influences the light fixture radiating effect.In the face of heat dissipation problem, general settling mode comprises two kinds of the passive heat radiation of aluminium alloy and fan forced heat radiations now.The passive heat radiation of aluminium alloy has tangible deficiency: the rate of heat dispation of aluminium is little, and the dust that light fixture accumulated on the lamp housing after use a period of time is formed dirt easily, has influenced the heat radiation of light fixture, thereby has influenced the life-span of light fixture.The fan forced heat radiation also has the shortcoming of self: the mode power consumption that relies on rotatable parts to dispel the heat is big, reliability is not high, the whole lamp efficient of influence.
The utility model content
The utility model technical problem to be solved provides a kind of good heat dissipation effect, good reliability, electromagnetic viscosimeter heat abstractor that Luminaire efficiency is high.
The technical scheme that the utility model technical solution problem is adopted is: the electromagnetic viscosimeter heat abstractor; Comprise magnetic core, coil, blade and support; Said coil winding is on the surface of magnetic core; Said magnetic core is connected with an end of support, and the other end of support is connected with blade, and the adjacent setting with magnetic core of blade.
The beneficial effect of the utility model is: utilize solenoid under the effect of alternating voltage, to produce magnetic field; The phase change of the magnetic of coil and blade is asynchronous; Peer repels each other different grade and inhales mutually; The blade dither has stirred ambient air and has flowed fast, and forms convection current with the heat generating components ambient air, thereby reduces lamp temperatures fast.The utility model has remedied the deficiency of fan forced heat radiation and the passive heat radiation of aluminium alloy in entire work process, given prominence to the advantage that under the effect of magnetic field, reduces lamp temperatures fast, good heat dissipation effect, reliability height.

The specific embodiment
As depicted in figs. 1 and 2; The LED electromagnetic viscosimeter heat abstractor of the utility model is made up of magnetic core 1, coil 2, blade 3, support 4, cushion pad 5, securing member 6 and kuppe 7; Coil 2 is wound on the surface of magnetic core 1, and magnetic core 1 directly is connected with support 4 through the mode of die casting.One end of blade 3 is connected with support 4, and the other end is connected with kuppe 7, and blade 3 and magnetic core 1 adjacent setting.
Magnetic core 1 adopts the material of soft magnetism to process, and can select materials such as pure iron, silicon steel, permalloy for use.Magnetic core 1 can be shapes such as cylindrical, cuboid.
Blade 3 is the thin slices that adopt easily the material that magnetizes, have soft magnetism to process, like carbon steel, wolfram steel, alnico alloy materials such as (Fe Ni Co Cu).Blade 3 has good pliability, and it is fixed on the support 4 through securing member 6, and securing member 6 can be selected rivet or screw etc. for use.
Between blade 3 and securing member 6, also be connected with cushion pad 5, the effect of cushion pad 5 be guarantee blade 3 in magnetic field effect do the vibration of rule down, when also having guaranteed simultaneously blade 3 vibrations and noiselessness generation between the support 4.Cushion pad 5 can be selected the cushion of rubber blanket or other kinds for use, and cushion pad 5 all is fixed on the support 4 through securing member 6 with blade 3.
Support 4 adopts non-ferromagnetic materials such as aluminium alloy, copper alloy or stainless steel to process, and intensity is good, is used for connecting blade 3 and magnetic core 1, has played the effect of securing device.
When connecting alternating voltage at coil 2 two ends, hot-wire coil can produce stronger magnetic field, and magnetic core 1 is magnetized simultaneously, has produced and the same magnetic field of coil 2 directions; Magnetic strengthens, and blade 3 is magnetized polarization under the effect in stack magnetic field; Heteropole is inhaled mutually, and when the direction of voltage changed, respective change also took place the polarity of magnetic core 1; Because blade 3 has the characteristic of soft magnetism, magnetic core 1 is asynchronous with the phase change of the magnetic of iron flake sheet 3, produces peer and repels each other.Peer repels each other different grade and inhales mutually, and because blade 3 its own inertial and elasticity, blade 3 produces dithers.The dither of blade 3 has stirred flowing fast of surrounding air, and forms convection current with the heat generating components ambient air, can reach the temperature of quick conduction and cooling light fixture, has increased the service life of light fixture and the effect of light efficiency.
Kuppe 7 can adopt funnel structure, and is as shown in Figure 4, and purpose is to effectively utilize the air-flow that blade 3 vibrations produce, and air-flow is flowed out by definite direction behind kuppe 7, guarantees best radiating effect.
In actual use, can organize the electromagnetic viscosimeter heat abstractors of the utility model more according to the actual conditions assembling, thereby arrive required heat radiation purpose; Like Fig. 4 and shown in Figure 5; Embodiment among the figure is combined by three the utility model electromagnetic viscosimeter heat abstractors, and heat abstractor is arranged on a side of heater, when this heat abstractor is all passed to alternating voltage; Hot-wire coil produces magnetic field, and blade is because its own inertial and elasticity all produce dither.The dither of blade has stirred flowing fast of surrounding air, and forms convection current with the heat generating components ambient air, thereby reaches the quick heat radiating effect of this device.
