For example, the fluorescent tube of an embodiment of the present invention, wherein the heat-conducting layer of the NEW TYPE OF COMPOSITE heat dissipation alloy, Include each component of following mass parts:
60 parts~65 parts of copper, 55 parts~60 parts of aluminium, 0.8 part~1.2 parts of magnesium, 0.2 part~0.5 part of manganese, titanium 0.05 part~0.3 Part, 0.05 part~0.1 part of chromium, 0.05 part~0.3 part of vanadium, 0.3 part~0.5 part of silicon and 0.1 part~0.3 part of graphene.
First, it is 60 parts~65 parts of copper and 55 parts~60 parts of aluminium that above-mentioned heat-conducting layer, which contains mass parts, can be made The coefficient of heat conduction of heat-conducting layer is maintained at 320W/mK~345W/mK, described in ensureing that heat-conducting layer can will absorb by heat-sink shell The heat that LED sub-light sources and OLED sub-light sources generate is quickly transmitted to heat dissipating layer, and then prevents heat from being accumulated on heat-conducting layer, Hot-spot phenomenon is caused to generate.Compared with the existing technology, merely use price costly and the larger copper of quality, it is above-mentioned to lead Thermosphere can not only ensure that quickly the heat transfer by heat-sink shell was to heat dissipating layer, but also have lighter weight, be easily installed casting, price Less expensive advantage.Meanwhile compared with the existing technology, the aluminium alloy for merely using heat dissipation effect poor, above-mentioned heat-conducting layer tool There is more preferably heat transfer property.
Next can greatly improve the heat conductivility of the heat-conducting layer by 0.1 part~0.3 part of graphene of addition, Preferably by the heat transfer passed over from heat-sink shell to heat dissipating layer.
Finally, it is 0.8 part~1.2 parts of magnesium, 0.2 part~0.5 part of manganese, 0.05 part~0.3 that heat-conducting layer, which contains mass parts, The titanium, 0.05 part~0.1 part of chromium, 0.05 part~0.3 part of vanadium and 0.3 part~0.5 part of silicon of part, so as to improve heat-conducting layer Mechanical performance and high temperature resistance, e.g., mechanical performance includes but is not limited to yield strength, tensile strength.For example, heat-conducting layer The magnesium for being 0.8 part~1.2 parts containing mass parts, can assign heat-conducting layer yield strength and tensile strength to a certain extent, by In the fabrication process in NEW TYPE OF COMPOSITE heat dissipation alloy, it needs heat-sink shell, heat-conducting layer and heat dissipating layer entirety punching press being integrally formed, This just needs heat dissipating layer to have stronger yield strength, to prevent heat dissipating layer from being generated in process by favourable opposition compression Non-reversible deformation, and then ensure the proper heat reduction performance of NEW TYPE OF COMPOSITE heat dissipation alloy.When the relative mass of magnesium is too low, e.g., matter When measuring part less than 0.8 part, it cannot substantially ensure that the yield strength of heat-conducting layer is met the requirements, however, the relative mass when magnesium is excessively high When, such as when mass parts are more than 1.2 parts, and can make the ductility and heat conductivility dramatic decrease of heat-conducting layer.For example, heat conduction The iron that layer is 0.2 part~0.8 part containing mass parts, can assign the higher high temperature resistance of heat-conducting layer and high temperature resistant mechanicalness Can, the processing for being conducive to heat-conducting layer is cast.

Next can effectively improve the heat dissipation performance of the heat dissipating layer by 5 parts~15 parts of graphene of addition, into And it will can be rapidly lost in extraneous air dielectric from the heat that the heat-conducting layer is transmitted to.
Finally, it is 5.5 parts~10.5 parts of silicon, 0.3 part~0.7 part of magnesium, 0.05 part~0.3 that heat dissipating layer, which contains mass parts, The copper, 0.2 part~0.8 part of iron, 0.2 part~0.5 part of manganese, 0.05 part~0.3 part of titanium, 0.05 part~0.1 part of chromium of part And 0.05 part~0.3 part of vanadium, the heat dissipation performance of heat dissipating layer can be significantly improved.For example, heat dissipating layer contains mass parts is 5.5 parts~10.5 parts of silicon and 0.05 part~0.3 part of copper, it can be ensured that heat dissipating layer has good mechanical properties and lighter weight The advantages of, at the same time it can also further improve the heat-conductive characteristic of heat dissipating layer, further ensure that heat dissipating layer can will be via heat absorption Layer and heat-conducting layer transmit after after-heat consistent scatter away, and then prevent heat from being accumulated on heat dissipating layer, cause office Portion's superheating phenomenon.
In order to further increase the tensile strength of the heat dissipating layer, for example, it is 0.8 part that the heat dissipating layer, which further includes mass parts, ~1.2 parts of lead (Pb), when the lead that heat dissipating layer contains 0.8 part~1.2 parts can improve the tensile strength of heat dissipating layer, in this way, can When striking out radiating fin, i.e. laminated structure to prevent that heat dissipating layer ought be cast, due to being pullled stress by excessive punching press And it is broken.
In order to further increase the high temperature oxidation resistance of the heat dissipating layer, for example, the heat dissipating layer further includes mass parts It for 0.05 part~0.08 part of niobium (Nb), is found through many experiments evidence and theory analysis, when the mass parts of niobium are more than 0.05 part When, the antioxygenic property of heat dissipating layer can be greatlyd improve, it will be understood that heat dissipating layer as in LED street lamp radiator with the external world The maximum component of air contact area, it is more demanding to high temperature oxidation resistance.However, the mass parts when niobium are more than 0.08 part When, the magnetism of heat dissipating layer can be caused to sharply increase, the other component in fluorescent tube can be had an impact.
In order to further increase the heat dissipation performance of the heat dissipating layer, for example, heat dissipating layer further include mass parts be 0.05 part~ 0.2 part of germanium (Ge) can play the raising of the heat dissipation performance of heat dissipating layer unexpected when the mass parts of germanium are more than 0.05 part Effect and the brittleness of heat dissipating layer can be made to increase however, the quality accounting when germanium is excessive, such as when the mass parts of germanium are more than 0.2 part Add.
Above-mentioned NEW TYPE OF COMPOSITE heat dissipation alloy is by being sequentially overlapped the setting heat-sink shell, the heat-conducting layer and the heat dissipation Layer, and the heat-conductive characteristic of the heat-sink shell, the heat-conducting layer and the heat dissipating layer successively decreases successively, forms heat-conductive characteristic ladder Degree, for fine copper material radiator, under the premise of ensuring heat dissipation performance, weight is greatly lowered;Compared in the market For a large amount of existing aluminum alloy material radiators, heat dissipation performance greatly enhances.
