Description

A kind of anticorrosion graphene radiator

Technical field

The utility model belongs to LED lamp heat sink technical field more particularly to a kind of anticorrosion graphene radiator.

Background technique

LED street lamp mainly uses Aluminium Radiator to radiate at present, but since electronics integrates higher and higher, radiating requirements Also corresponding to provide, common Aluminium Radiator has been difficult to meet high-end product radiating requirements.Excellent in view of graphene new material dissipates Has there is graphite alkene radiator in thermal characteristics, there is the polymer composites graphene radiator such as modification of nylon PA, but the material Matter radiator is due to substrate poor thermal conductivity, although modified heating conduction increases at multiple, also only reaches the left side 20-50W/mK The right side, is far below original Aluminium Radiator, and effect is unobvious.Another scheme is directly to coat stone on original Aluminium Radiator Black ene coatings are used for improving radiating effect, but encounter another technical problem, are exactly that coating adhesion is poor, antiseptic property is difficult to Meet outdoor requirement.

Anticorrosive paint dosage in the industry is very big at present, but can anti-corrosion but thermally conductive coating it is rare, and Often antiseptic property is bad for existing heat-conductive coating, causes the corrosion and loss of the metallic heat sinks in industry, or even every It to overhaul in year or with changing two to three times, seriously reduce production efficiency, increase production cost.

Preferably, the second coating is graphite ene coatings.

Preferably, the first coating is slurry priming paint；The slurry priming paint is by graphite-epoxy alkene dust primer and graphite Alkene is mixed.

Preferably, the substrate middle position is equipped with threading hole；Waterproof connector is connected on the threading hole.

Preferably, the radiating fin is equipped with more tall person's cone screwed lock attached columns；The cone screwed lock attached column Root diameter (RD) 4.0mm, the direct 2.0mm in tail portion.

Preferably, the substrate and radiating fin are made of aluminum products.

Compared with prior art, the technical solution of the utility model has the advantage that anti-corrosion provided by the utility model Graphene radiator is lost, both graphene heat dissipation characteristics and graphene anti-corrosion property merges well, radiates and imitates in optimization It can be very good to reach outdoor anti-soda acid anticorrosion and fine adhesion effect on the basis of fruit.Most suitable application and open air, are answered It is extensive with prospect, there is very much real applied value, is worthy to be popularized.

Detailed description of the invention

FIG. 1 is a schematic structural view of the utility model.

Fig. 2 is the partial enlarged view of the utility model A.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Please refer to shown in attached drawing 1: the utility model provides the following technical solutions: a kind of anticorrosion graphene radiator, packet Include substrate 1 and radiating fin 2；The radiating fin 2 is fixedly mounted on substrate 1；The substrate 1 and radiating fin 2 are equipped with First coating 3 and second coating 4；The first coating 3 is with a thickness of 1.0um~5.0um；The second coating 4 is with a thickness of 5.0um ~12.0um；The radiating fin 2 is wave-shaped, and the bottom width of the radiating fin 2 is 2.0mm, and top width is 1.0mm。

Specific the utility model radiator is aluminum product as radiator substrate, wherein after Aluminium Radiator molding, The graphene anticorrosion slurry priming paint of one layer of high adhesion force, priming paint are coated by removing grease stain pickling process, then in spreader surface Upper layer coats active material to offset extraneous chemical attack reaction, protects radiator and material main body.Finally sprayed in outermost layer One layer of graphene thermal dispersant coatings are applied, achieve the effect that high efficiency and heat radiation.

Wherein slurry priming paint is graphite-epoxy alkene dust primer, which adds 0.5%-1.5%'s Graphene is mixed, and is spliced to form strict labyrinth type physical barriers after coating coating mutually, and isolation corrosion factor enters, So as to protect metal not corroded, while can be formed with Aluminium Radiator substrate after the coating of graphite-epoxy alkene dust primer Intermolecular combination, adhesive force is good, not easily to fall off.Finally again on the Aluminium Radiator of graphene dust primer coat one layer of height Thermal conductivity graphene powder adjusts the graphene added with 5.0-10% in the high thermal conductivity graphene powder, using graphene high-termal conductivity, Anticorrosion graphene radiator after being performed integrally promotes the left side 10-15% than the radiator heating conduction of uncoated graphite ene coatings The right side, the current insufficient technical problem of aluminum radiator heat-dissipation of very good solution, due to being coated with graphite-epoxy alkene dust primer With high thermal conductivity graphene powder, not only radiator heat-dissipation performance is guaranteed, and also has very strong anti-soda acid anticorrosive property Can, adhesive force is again good, and basic perfect solves heat dissipation and corrosion-resistant technical problem at present.

Further, wavy radiating fin 2, the fluting of radiating fin 2 direction are equipped at intervals on graphene radiator It is consistent with wagon flow direction after quasi- installation, facilitate natural wind heat loss through convection, specific adjacent radiating fin spacing is 5.0mm, bottom Portion's width is 2.0mm, and top width is that 1.0mm and natural taper shrink molding, done in corresponding screw locking position it is conical, Root diameter (RD) 4.0mm, the direct 2.0mm in tail portion, natural taper shrink molding, this design is not only able to satisfy screw locking fixation and wants It asks, and since conical surface product is larger, heat dissipation area can be increased, utilize radiator integral heat sink effect.And this is practical new Type can cooperate water-proof silica-gel circle and LED light source module and light distribution lampshade to form required LED module, can be equipped with scheme disassembly Aviation plug is conducive to replacement.

Further, 1 middle position of substrate is equipped with threading hole 11；Waterproof connector 12 is connected on the threading hole, electricity Connection uses.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
