Description
Technical field
The utility model relates to a kind of LED radiator, is specifically related to a kind of LED radiator of using hot pipe technique, belongs to LED illuminating product technical field.
Background technology
LED is as a kind of novel lighting, and it is obvious to all in the advantage aspect energy-conservation, is worth promoting.
But LED only only has 1/3 energy can be transformed into visible light in when work, and remainder can become heat.LED is because single light-emitting area is narrow, and large-scale integrated in the circuit board, forms a larger light emitting source usually, can cause thus the amount of heat accumulation, causes temperature to raise.Too high temperature not only can make the decrease in efficiency of LED, accelerates the aging of LED, reduces the life-span, and height can directly burn out circuit board, broken ring whole system to a certain extent.Although therefore its efficient of LED is much higher than ordinary incandescent lamp, its heat radiation is still a major issue.
For low power LED, usually module directly is fixed on Section Bar Heat Sinks, be used for strengthening area of dissipation, carry out Natural Heat Convection with air in environment.But along with the increase of LED range of application, progressively use in occasions such as industrial and mineral, squares, power improves constantly, and therefore heat radiation is proposed higher requirement.
Because the material of radiator usually used is aluminium, itself has certain thermal resistance, if merely strengthen the physical dimension of radiator, heat radiation approach from the module to the spreader surface is longer so, the larger temperature difference can appear, the temperature difference of radiator and environment can be very little like this, greatly restricts its heat-sinking capability.Therefore, for high-power LED, just need a kind of novel radiator to match.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of LED radiator with structure improved application hot pipe technique, to overcome described defective of the prior art.
The utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of LED radiator of application hot pipe technique of simple in structure, good heat dissipation effect.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of LED radiator of using hot pipe technique, it comprises a hollow tube, be marked with a liquid level in described hollow tube, and be vacuum structure in this hollow tube, be provided with some fin in the outer circumference surface of described hollow tube.
The LED radiator of application hot pipe technique of the present utility model further is set to: described liquid level is specially water layer.
The LED radiator of application hot pipe technique of the present utility model also is set to: described each fin stretches out along the diametric(al) of hollow tube.
Compared with prior art, the utlity model has following beneficial effect: the LED radiator of application hot pipe technique of the present utility model has utilized the temperature effect that waits of heat pipe, avoided the inner problem of traditional entity radiator, the problem includes: the thermal resistance problem, make the physical dimension that continues to increase radiator become possibility, successfully solved the heat dissipation problem of great power LED.
Description of drawings
Fig. 1 is the sectional drawing of the LED radiator of application hot pipe technique of the present utility model.
Fig. 2 is the top view of the LED radiator of application hot pipe technique of the present utility model.
The specific embodiment
See also shown in Figure of description 1 and accompanying drawing 2, the utility model is a kind of LED radiator of using hot pipe technique, and its bottom is equipped with a LED module 9.
Described LED radiator comprises a hollow tube 1, is marked with a liquid level 2 in described hollow tube 1.In the present embodiment, described liquid level 2 is specially water layer 2, certainly, and the liquid that also can adopt other energy gas-liquids to transform.
Be vacuum structure in described hollow tube 1, it is evacuated and seals after a certain amount of liquid level 2 of perfusion, and forms heat pipe.
Outer circumference surface in described hollow tube 1 is provided with some fin 3.Each fin 3 stretches out along the diametric(al) of hollow tube 1.
The operation principle of the LED radiator of application hot pipe technique of the present utility model is as follows: when LED module 9 work, liquid level 2 in hollow tube 1 is heated, evaporation rapidly, absorb evaporation latent heat under vacuum state, permeates in the cavity of whole hollow tube 1 with the velocity of sound with steam.When steam runs into temperature slightly during low heat emission sheet 3 wall, condense into liquid, get back to endotherm section by gravity current, emit simultaneously evaporation latent heat, successively the circulation, constantly heat is delivered to the inner chamber of hollow tube 1 from LED module 9 back locations, then by heat exchange with dissipation of heat in air.
The above specific embodiment is only the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within make any modification, be equal to replacement, improvement etc., within all should being included in the protection domain of this creation.
