It is appreciated that the heat sink bears biggish since several LED lamp beads are directly mounted at the heat sink
Heat carries, especially the higher situation of power and brightness requirement, therefore, it is necessary to the heat dissipation performance performance of the heat sink is improved,
In order to further increase the heat dissipation performance of the heat sink, to improve the heat dissipation performance of the circulating type illuminator entirety, example
Such as, referring to Fig. 7, heat sink 500 includes safe floor 510, heat-conducting layer 520, heat transfer layer 530 and the heat dissipating layer being cascading
540, the LED lamp bead is set to the safe floor.
For example, the circulating type illuminator of an embodiment, the safe floor include each group of following mass parts
Point: 80 parts~90 parts of silicon nitride, 30 parts~45 parts of titanium dioxide, 2 parts~8 parts of silica, 2 parts of kaolin~15 parts, lightweight
0.5 part~2 parts and 0.2 part~0.5 part of rare earth oxide of calcium.For example, the rare earth oxide includes lanthana, cerium oxide, oxygen
Change at least one of praseodymium, europium oxide and terbium oxide, for example, the quality of lanthana, cerium oxide, praseodymium oxide, europium oxide and terbium oxide
Than for 1:1:1:1:1.
Above-mentioned safe floor has insulation effect good, the advantage that thermal coefficient is big and thermal expansion coefficient is low, in this way, working as LED light
When the heat of pearl is directly delivered to the safe floor, the safe floor can be quick and in time gathers LED lamp bead near zone
The heat transfer of collection is to the heat-conducting layer, to ensure the normal work of LED lamp bead.Secondly as the safe floor and LED lamp bead
It directly contacts or is closer, the thermally conductive load undertaken is maximum, and above-mentioned safe floor uses silicon nitride as primary raw material, and mixes
It can have lower thermal expansion coefficient with other materials, so as to avoid generating between the safe floor and the heat-conducting layer
Gap, and avoid the safe floor itself from generating gap, and then can lead to avoid what is generated behind the gap and gap filling air
The problem of hot coefficient reduces.Further, since directly contacting or being closer between the safe floor and LED lamp bead, is easy hair
Raw electric elements, the case where directly contact with the safe floor such as conducting wire, above-mentioned safe floor uses silicon nitride as primary raw material,
And mixed other materials can have preferable insulating properties, so as to avoid the safe floor from being powered, to improve described
The security performance of circulating type illuminator, safety standard are higher.
For example, the circulating type illuminator of an embodiment, the heat-conducting layer include each group of following mass parts
Point: 90 parts~95 parts of nano-graphene fiber, 0.5 part~15 parts of multi-walled carbon nanotube, 0.1 part~5 parts of single-walled carbon nanotube and
0.1 part~10 parts of carbon nano-fiber.
Above-mentioned heat-conducting layer uses nano-graphene fiber for primary raw material, and uses multi-walled carbon nanotube, single
Pipe and carbon nano-fiber are as auxiliary material, so that the heat-conducting layer has biggish thermal coefficient, heat-conducting effect is preferable.It needs
, it is noted that addition multi-walled carbon nanotube, single-walled carbon nanotube and carbon nano-fiber, can form micro- dissipate in the heat-conducting layer
Heat pipeline, for further increasing heat dissipation performance, in this way, the heat of the safe floor can quickly and be in time transferred to institute
It states in heat transfer layer.
It should be noted that because the LED lamp bead shine the heat generated pass through before two layers, i.e., the described safe floor and described
After heat-conducting layer, the heat loss of some is understood into extraneous air.Further, since the higher cost of the heat-conducting layer,
Main reason is that the primary raw material of the heat-conducting layer is the higher nano-graphene fiber of preparation cost, therefore, based on described
In the case that the heat transfer and heat dissipation load of heat transfer layer are relatively small, the more common metal in current market is can be used in the heat transfer layer
Heat sink material, to achieve the effect that reduce cost and obtain preferable heat transfer property.
For example, the heat transfer layer of an embodiment of the present invention comprising each component of following mass parts: 85 parts~90 parts of copper,
2 parts~4.5 parts of titanium, 0.1 part~0.3 part of nickel, 0.2 part~1.2 parts of magnesium, 0.2 part~0.7 part of iron, 0.2 part of vanadium~1.2 parts, manganese
0.1 part~0.4 part and 0.1 part~0.3 part of chromium.
Above-mentioned heat transfer layer has preferable heat transfer property using what 85 parts~90 parts of copper can make heat transfer layer, so as to
More quickly the heat being transmitted on the heat-conducting layer is passed, and then is evenly dispersed in the structure of the heat transfer layer entirety
On, to prevent heat from accumulating on the contact position between the heat-conducting layer and the heat transfer layer, cause hot-spot phenomenon
It generates.In addition, above-mentioned heat transfer layer has thermal coefficient high, perfect heat-dissipating, good mechanical property and the advantages of cost is relatively low, such as
This, when the heat transfer of the heat-conducting layer gives the heat transfer layer, then the heat that the heat-conducting layer is absorbed into can be more fast
It is transmitted in the heat dissipation fastly, and during heat transfer, the heat of part can also be directly delivered to by the heat transfer layer
In extraneous air.
It should be noted that when the heat that the LED lamp bead generates passes through three first layers, i.e., the respectively described safe floor, institute
After stating heat-conducting layer and the heat transfer layer, has relatively large a part of heat and scatter and disappear in air medium in transmitting, in addition, by
It is copper in the primary raw material of the heat transfer layer, therefore heavier mass loads relatively small feelings based on heat dissipating layer heat dissipation
Under condition, it is preferable that the heat dissipating layer can be used heat dissipation effect, lighter in weight, lower-cost material, with reach reduce cost and
Weight, and obtain the effect of preferable heat dissipation performance.
For example, the heat dissipating layer of an embodiment of the present invention comprising each component of following mass parts: 70 parts~75 parts of aluminium,
35 parts~45 parts of copper, 0.2 part~0.7 part of magnesium, 0.1 part~0.3 part of nickel, 0.2 part~0.7 part of iron, 0.2 part of manganese~0.5 part, titanium
0.1 part~0.3 part, 0.05 part~0.1 part of chromium and 0.1 part~0.3 part of vanadium.
Above-mentioned heat dissipating layer uses 70 parts~75 parts of aluminium and 35 parts~45 parts of copper, and the heat dissipating layer can be made still to have
Preferable heat dissipation performance, so as to ensure that the heat dissipating layer can rapidly dissipate the heat passed over by the heat transfer layer
It loses in air medium, e.g., is dissipated in inside the heat-dissipating cavity, and then heat is avoided to accumulate on the heat dissipating layer, causes
Hot-spot phenomenon generates.Compared with the existing technology, merely use price costly and the biggish copper of quality, above-mentioned heat dissipating layer
Both there is good heat dissipation effect, there can be lighter weight rapidly by heat loss into air, be easily installed casting, price
