Description

The radiator structure of electronic building brick

Technical field

The present invention is for a kind of radiator structure is provided, espespecially a kind of low cost of manufacture, production fast, manufacturing process's minimizing, environmental protection and the high radiating structure of electronic assemblies of radiating efficiency.

Background technology

Press, due to light-emitting diode (Light Emitting Diode, LED) be to utilize electric energy to be converted into the principle of luminous energy, in semiconductor, two terminals of both positive and negative polarity apply voltage, when electric current passes through, when electronics is combined with electric hole, dump energy just discharges with the form of light, comply with the difference of the material of its use, and can just make photon energy produce the light of different wave length in rank with it, because it has that brightness is high, the advantage of power saving, life-span length, and be applied to widely in all science and technology and daily life, become the indispensable articles for use of common people's lighting apparatus.

And the power of LED input only has 15～20% to convert light to, all the other 80～85% convert heat to, if these heat are not discharged outside in good time, will make so LED crystal grain interface temperature too high and affect luminous efficiency and luminescent lifetime.In practical, high power, high brightness LED throw light on its space of living in and position, to the good no great key that has of dispelling the heat.

A kind of improvement of LED lamp radiating module as shown in known techniques, it has LED lamp substantially, circuit board, radiating fin and heat conduction copper post form, wherein, this heat conduction copper post generally becomes T shape, and on circuit board, in LED lamp position, be provided with a hole, in radiating fin, be positioned at circuit board hole place and be provided with a shrinkage pool, make heat conduction copper post be inserted shrinkage pool, and make T shape hold the shrinkage pool end limit that is arranged in the hole of circuit board and is attached at radiating fin, by this, by LED lamp directly and the T shape end in contact of heating column, make heat directly by copper post, be transmitted to radiating fin, and obtained the object person of the heat radiation efficiently and effectively.

The improvement of right above-mentioned LED lamp radiating module, when using, exists following point and disappearance to wait to improve:

This radiating mode is the action of must punching on aluminium matter heat radiation pedestal, to be formed with shrinkage pool, then again heat conduction copper post is inserted in this shrinkage pool, this kind of mode not only takes time and effort, and and do not meet cost economic benefit, many shrinkage pool processing procedures in operation, its cost and production time-histories all will be consumed and incur loss through delay, therefore, not good in industrial competitiveness, again and, cause for this reason known techniques need be holed in advance, easily cause this shrinkage pool excessive or too small, while making heat conduction copper post insert shrinkage pool because elasticity is bad so that adaptation is not good (producing space in around), its radiating effect is reduced, and there is space because producing, in space, easily produce impurity, and then affect radiating effect, separately, principle of expanding with heat and contracting with cold processing procedure is adopted by this radiating module system, also consumptive material consuming time not only on processing procedure.

Summary of the invention

Therefore the present invention's inventor designs the patent of invention person of the radiating structure of electronic assemblies that this kind of low cost of manufacture, production fast, manufacturing process's minimizing, environmental protection and radiating efficiency are high.The present invention's main purpose is: the aluminium matter radiating seat system on this radiator structure is connected with a radiating fin, and be to be provided with at least one to close the mode of being forced into by provided thereon of at least one copper post heat carrier with mould on this aluminium matter heat radiation pedestal, and on the relative position of these copper post heat carriers, be to be respectively arranged with several electronic building bricks, while producing heat energy in order to do starting start when these electronic building bricks, by being oppositely arranged of these copper post heat carriers, effectively heat energy is derived rapidly, by above-mentioned technology, can be the action of must punching on aluminium matter heat radiation pedestal for this existing radiating mode of the improvement of commonly using LED lamp radiating module, to be formed with shrinkage pool, then again heat conduction copper post is inserted in this shrinkage pool, this kind of mode not only takes time and effort, and and do not meet cost economic benefit, many shrinkage pool processing procedures in operation, its cost and production time-histories all will be consumed and incur loss through delay, therefore, not good in industrial competitiveness, again and, cause for this reason known techniques need be holed in advance, easily cause this shrinkage pool excessive or too small, while making heat conduction copper post insert shrinkage pool because elasticity is bad so that adaptation is not good (producing space in around), its radiating effect is reduced, and there is space because producing, in space, easily produce impurity, and then affect radiating effect, separately, principle of expanding with heat and contracting with cold processing procedure is adopted by this radiating module system, on processing procedure, not only the problem points of also consumptive material consuming time is broken through, reach by punching press or close the mode of being forced into copper post heat carrier is inserted on aluminium matter heat radiation pedestal, and corresponding with the electronic building brick that produces heat energy, make it improve heat-conducting effect, and reduction manufacturing cost, produce fast, the practical improvement of manufacturing process's minimizing and environmental protection.
