Abstract
The utility model discloses a high-power LED (light-emitting diode) radiator, which is characterized by comprising a liquid accommodating chamber (1). The top of the liquid accommodating chamber (1) is provided with a tympanic membrane (1a), a spiral radiating tube (2) is arranged on the tympanic membrane (1a) and is supported by a central tube (3) arranged at the center of the tympanic membrane (1a), the inner end of the radiating tube (2) is communicated with the liquid accommodating chamber (1) through the central tube (3), and the outer end of the radiating tube (2) extends downwards to be communicated with the liquid accommodating chamber (1). The high-power LED radiator has a compact structure and a unique and delicate design, can radiate heat emitted by an LED through continuous cycles of vaporization and liquefaction of cooling fluid, and can achieve significant radiating effect. Moreover, the whole cycles need no external force for driving.
Description
Technical field
The utility model relates to the heat abstractor of a kind of great-power electronic or optical element, particularly a kind of radiator of great power LED.
Background technology
LED is because energy-conservation, advocate in country under the overall background of energy-conserving and environment-protective and used in a large number, LED work will produce heat, and along with the time lengthening temperature can constantly raise, too high to the cooling of LED and heat radiation to prevent temperature, be unusual core problem in design and the application process.At present, the method that generally adopts is by improving LED baseplate material, encapsulating structure, with improving the heat dissipation problem that heat conducting method solves LED both at home and abroad.But for the great power LED that is used to occasions such as throwing light on, this method is difficult to take effect.Simultaneously, for illuminating great power LED, the cost of its cooling segment can not be very high, and size does not allow excessive.In addition, when the thermo-contact thermal resistance of heat sink and device etc., after a certain scope, further reduce and to cause increasing considerably of cost.Therefore, the cooling means of existing heat conduction can not solve the heat dissipation problem of great power LED.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of at great power LED cooling effective radiator.
The technical solution of the utility model is as follows: a kind of high-power LED radiator, its key is: comprise the Sheng sap cavity, this Sheng sap cavity top is an eardrum, described eardrum top is provided with radiating tube, this radiating tube twist, and the central tube that is provided with by eardrum central authorities supports, and described radiating tube the inner is by central tube and Sheng sap cavity UNICOM, and described radiating tube outer end is extended downwards and contained sap cavity UNICOM.
Contain the cooling fluid of packing in the sap cavity, containing the sap cavity bottom surface is the LED substrate, and the led board heating temp raises, vaporize simultaneously by the cooling fluid draw heat, containing the sap cavity top is eardrum, and cooling fluid vaporization back guarantees to contain the sap cavity internal pressure and can not increase, and promptly is in order to guarantee that the cooling fluid boiling point can not raise.Cooling fluid after the vaporization enters radiating tube through central tube, the spiral radiating tube of process is progressively lowered the temperature and is become liquid, because spirality middle part flash is along low, cooling fluid in the radiating tube is back to the Sheng sap cavity at last owing to the gravity reason flows to the edge from the centre, progressively emits heat in whole reflux course.Radiating tube is positioned at and contains the sap cavity top simultaneously, leaves certain space between radiating tube and the Sheng sap cavity, is used for cross-ventilation and takes away the heat that radiating tube sends.Whole spiral radiating tube is supported on by central tube and radiating tube outer end and contains on the sap cavity.
Above-mentioned radiating tube is that three tube side-by-sides coilings are formed, described three arms inner all with central tube UNICOM, all extend downwards and Sheng sap cavity UNICOM these three arm outer ends, and the outer end of three arms is evenly distributed on the edge of Sheng sap cavity.Radiating tube is that three tube side-by-side coilings are formed, and has increased area of dissipation, and the gas that central tube enters can enter radiating tube from a plurality of directions, is evenly distributed, and it is also more even to dispel the heat, and radiating effect can be better.The outer end of three arms is evenly distributed on the edge of containing sap cavity, and the outer end of arm is stressed more even like this, heat radiation is supported better.
As optimization, the inner and tangential UNICOM of central tube of above-mentioned radiating tube.
The groove of above-mentioned eardrum is also arranged for spirality.Spirality all be the middle part flash along low, gas makes progress away, gas is easy to just flow to spirality eardrum central authorities along groove, enters central tube, it is better to design gas fluidity like this, more smooth and easy.
Beneficial effect: the utlity model has compact conformation, design is unique ingenious, by cooling fluid, constantly vaporization, liquefaction cycle are taken away the heat that LED sends, and radiating effect is remarkable, and without any need for external force promote whole circulation.
Description of drawings

Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, a kind of high-power LED radiator of the utility model is formed by containing sap cavity 1, radiating tube 2 and central tube 3 etc., and containing sap cavity 1 top is eardrum 1a, directly utilizes the LED substrate as the base plate of containing sap cavity.The groove of eardrum 1a also is a spirality, so eardrum 1a also is flash edge, a middle part step-down gradually.Described eardrum 1a top is provided with radiating tube 2, this radiating tube 2 twist, radiating tube 2 also is the middle part flash along step-down gradually.And radiating tube 2 is supported by the central central tube that is provided with 3 of eardrum 1a, and described radiating tube 2 the inners are by central tube 3 and contain sap cavity 1 UNICOMs, extension downwards of described radiating tube 2 outer ends and Sheng sap cavity 1 UNICOM.Radiating tube 2 is that three arms 4 coil composition side by side in the design, described three arms 4 inner all with central tube 3 UNICOMs, these three arm 4 outer ends are all extended downwards and are contained sap cavity 1 UNICOM, and radiating tube 2 is inner tangent with central tube 3, and the outer end of three arms 4 is evenly distributed on the edge of containing sap cavity 1.In fact three arms 4 have played certain supporting role, radiating tube 2 is supported on contains sap cavity 1 top.
Although below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic rather than determinate; those of ordinary skill in the art is under enlightenment of the present utility model; under the prerequisite of the utility model aim and claim; can make multiple similar expression, such conversion all falls within the protection domain of the present utility model.
