Further, described tubular cast comprises that by interior an accommodating cavity, an aluminium alloy cast layer and are covered in the aluminium alloy compression casting layer on this aluminium alloy cast layer outer peripheral face outwardly successively.
Compared to the prior art, the beneficial effect that the utility model produces is:
1, the utility model is simple in structure, practical, by described heat-conducting unit being located at described in each between heat-sink unit and heat-sink unit described in each being coupled to a heat radiation loop body for heat conduction mutually, once the LED unit on one of them heat-sink unit produces a large amount of used heat, just can be delivered to by heat-conducting unit other heat-sink unit, greatly improved heat dispersion of the present utility model, user can be according to actual demand, heat-sink unit is set up to many groups, like this can be so that heat dispersion of the present utility model be significantly improved, and then can meet the heat radiation requirement of great power LED completely.
2, in the utility model, by the tubular cast of described heat-conducting unit being arranged to be comprised of accommodating cavity, aluminium alloy cast layer and aluminium alloy cast layer, this spline structure not only has that quality is light, density is low, thermal diffusivity is good, hardness and the feature such as shock resistance dynamics is strong.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the generalized section of heat-conducting unit described in the utility model.
The specific embodiment
The specific embodiment of the present utility model is described with reference to the accompanying drawings.
See figures.1.and.2.A kind of high-power LED radiator 1 of architecture advances, comprise three heat-sink units 2, a LED unit 3, a LED lampshade 5 and a heat-conducting unit 4, described in each, the surface of heat-sink unit 2 is equipped with a radiating fin 20, and the back side that corresponds to these radiating fin 20 positions of a described heat-sink unit 2 is provided with described LED unit 3 therein, and described LED lampshade 5 is mounted on the heat-sink unit 2 that is furnished with described LED unit 3.Described heat-conducting unit 4 is located at described in each between heat-sink unit 2 and heat-sink unit described in each 2 is coupled to a heat radiation loop body for heat conduction mutually.Described radiating fin 20 is arranged and is formed by plural piece aluminium alloy heat sink interval.The present embodiment is by being located at described heat-conducting unit 4 described in each between heat-sink unit 2 and heat-sink unit described in each 2 being coupled to a heat radiation loop body for heat conduction mutually, once the LED unit 3 on one of them heat-sink unit 2 produces a large amount of used heat, just can be delivered to by heat-conducting unit 4 other heat-sink unit 2, greatly improved heat dispersion of the present utility model, user can be according to actual demand, heat-sink unit 2 is set up to many groups, like this can be so that heat dispersion of the present utility model be significantly improved, and then can meet the heat radiation requirement of great power LED completely.
See figures.1.and.2.Described in each, the inside of heat-sink unit 2 is provided with a pilot hole 21, and described heat-conducting unit 4 is the suitable tubular cast 40 of external diameter and described pilot hole 21.Described tubular cast 40 comprises that by interior an accommodating cavity 41, an aluminium alloy cast layer 42 and are covered in the aluminium alloy compression casting layer 43 on these aluminium alloy cast layer 42 outer peripheral faces outwardly successively.The present embodiment is by the tubular cast 40 that described heat-conducting unit 4 is arranged to be comprised of accommodating cavity 41, aluminium alloy cast layer 42 and aluminium alloy cast layer 42, and this spline structure not only has that quality is light, density is low, thermal diffusivity is good, hardness and the feature such as shock resistance dynamics is strong.
The aluminium alloy cast layer 42 being mentioned in the utility model is to adopt casting process to form cast tubes with aluminum alloy materials, and described aluminium alloy compression casting layer 43 is to adopt extrusion process to form a die-casting tube being coated on cast tubes outer peripheral face with aluminum alloy materials.
The extrusion process that the present embodiment is mentioned and casting process are the known technology of this area.
Wherein die casting is a kind of metal casting technique, is characterized in utilizing mold cavity to apply high pressure to the metal melting.Mould normally processes with the higher alloy of intensity, a bit similar injection mo(u)lding of this process.Most of die casting foundry goods are all nonferrous, for example zinc, copper, aluminium, magnesium, lead, tin and terne metal and their alloy.Because being generally only used in, extrusion process manufactures in batches large-tonnage product.Manufacture the parts of die casting comparatively speaking than being easier to, this general needs four key steps, and monomial cost accounting increment is very low.Die casting is particularly suitable for manufacturing a large amount of middle-size and small-size foundry goods, so die casting is most popular a kind of in various casting techniques.With Castingother technology, compare, the surface of die casting is more smooth, has higher dimensional uniformity, thereby use extrusion process can be so that foundry goods has outstanding dimensional accuracy.Because extrusion process has advantages of above, thereby it is widely used in processing wall thin foundry goods.
Casting is another kind of extremely conventional metal casting technique, is characterized under normal pressure, liquid monomer being injected in mould, through polymerization and curing molding becomes the goods identical with dies cavity shape.Cast molding is not generally exerted pressure, not high to the requirement of strength of equipment and mold, and less to product size restriction, in goods, internal stress is also low.Therefore, investment of production is less, can make the large-scale product of function admirable, but the production cycle is longer, after moulding, must carry out machining.On tradition casting basis, derive the methods such as perfusion, embedding casting, pressure pouring, rotated mold filing and spun casting.
Above are only the specific embodiment of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection domain.
