Abstract

The invention discloses a technical manufacturing method of a radiating electric wire. In order to solve the problems that when electric energy is transmitted through an existing electric wire, heat sinking is caused by heating, heat can not be well radiated, and the existing electric wire can not assist radiating, the technical manufacturing method includes the steps that insulating heat conduction plastic is used as a jacket of the electric wire in the extrusion molding production process of the electric wire, the thickness of the heat conduction plastic jacket is smaller than 5mm, a metal wire core is wrapped by the heat conduction plastic jacket, the electricity conduction and heat conduction metal wire core of the electric wire is made of metal such as aluminum, aluminum alloy, copper, copper alloy, iron and iron alloy, the radiating electric wire can be manufactured to be a single-core wire and can also be manufactured to be a multi-core cable with the multiple metal cores, the heat conduction plastic jacket can be designed to be in a convex-concave groove shape, or the whole radiating electric wire is in a spring annular shape, so that the heat radiating area is increased. According to the technical manufacturing method, the safety performance of the electric wire is not affected, meanwhile, the electric wire has the electricity conduction function and the heat conduction and radiating functions, the use safety of electric appliances is improved, and the temperature inside the electric appliances is reduced.

Description

A kind of fabrication techniques method of the electric wire that dispels the heat

Affiliated technical field

The invention belongs to electrical engineering and electric apparatus equipment manufacture technology field, be specifically related to a kind of fabrication techniques method of the electric wire that dispels the heat.

Background technology

In the manufacture technology field of electric wire, the skin of electric wire is used the low-down insulation plastic cement of conductive coefficient at present, main plaing a part insulated, the function of heat radiation does not have particular design, easily cause the security incident occurring because of heat deposition, simultaneously because the develop rapidly of electrical apparatus industry, some electric equipment products that need heat dissipation design (as LED energy-saving lighting lamp) have been there are, in the urgent need to number of ways and mode, solve heat dissipation problem, plastic cement has extraordinary heat loss through radiation ability, but the plastic cement that wire outer skin is used is at present because conductive coefficient is very low, there is serious obstruction in the conduction of heat in plastic cement, cause the heat on metal-cored in electric wire well not distribute.The technical know-how basis of patent of the present invention is: when thermal source and radiator are in contact with one another, thermal source and spreader surface vertical range are at 5mm and when following, and the conductive coefficient of radiator is only greater than 5W/ (mK) and just the impact of temperature difference is leveled off to 0.

accompanying drawing explanation

Figure of description 1 has provided the relation of conductive coefficient and conduction heat loss through convection, abscissa is conductive coefficient, ordinate is the temperature difference of thermal source and environment, various curves be thermal source and material surface distance (curve from left to right successively corresponding distance be: 1mm, 2mm, 3mm, 4mm, 5mm, 20mm).If distance is less than 5mm (from left to right the 5th curve), so as long as conductive coefficient is greater than 5W/ (mK), its heat-sinking capability just determined by convection current completely, and the temperature difference is less, distance is less, and conductive coefficient is just more inessential.

summary of the invention

In order to overcome existing electric wire electric energy transmitting, time heating causes heat sink, heat can not well distribute problem that can not auxiliary heat dissipation with existing electric wire, the invention provides a kind of fabrication techniques method of the electric wire that dispels the heat, this manufacture method can be when not affecting the fail safe of electric wire, make electric wire there is the function of heat conduction and heat radiation, improve fail safe and reduction electrical equipment internal temperature that electrical equipment uses.

The present invention solves the technical method that its technical problem adopts: in the extrusion molding production process of electric wire, use the heat conduction plastic cement of insulation as the crust of electric wire, this heat conduction plastic cement can be that following all kinds of plastic cement is the heat conduction plastic cement that base material is processed into: polyvinyl chloride, polyethylene, polypropylene, perfluoroethylene-propylene, polyolefin, polyurethane, polytetrafluoroethylene, perfluoroethylene-propylene, soluble poly tetrafluoroethene, polytrifluorochloroethylene, ethylene-chlorotrifluoro-ethylene copolymer, ethylene-tetrafluoroethylene copolymer, Kynoar, polyvinyl fluoride, haloflex, chlorosulfonated polyethylene, neoprene, dimethyl silicone rubber, methyl vinyl silicone rubber, methyl phenyl vinyl silicone rubber, fluorosioloxane rubber, nitrile silicone rubber, phenylene silicone rubber, phenylate support silicon rubber, polystyrene, chlorinated polyether, polyamide, polyimides, polyester, polyphenylene sulfide, polyamide 6, polyamide 46, polyamide 66, liquid crystal polymer, Merlon, polyphtalamide, polyether-ether-ketone, polybutylene terephthalate (PBT), thermoplastic elastomer (TPE) (phenylethylene, olefines, dienes, polyvinyl chloride-base, polyurethanes), acrylonitrile-butadiene-styrene (ABS) plastics, phenolic resins, be wrapped in heat conduction plastic cement skin thickness on metal core below 5mm, electric wire is used aluminium matter or aluminium alloy or copper or copper alloy, again or the metal such as irony or ferroalloy as the conductive and heat-conductive metal core of electric wire, heat radiation electric wire can be made single-core line, also can be made into the multi-core cable with many wires core, on heat conduction plastic cement crust, can be designed as emboss pit shape or whole heat radiation electric wire is spring ring-type, so that increase area of dissipation, reach the object of better heat radiation.

The invention has the beneficial effects as follows, can when not affecting the fail safe of electric wire, make electric wire not only there is the function of conduction, and there is the function of heat conduction and heat radiation, improve fail safe and reduction electrical equipment internal temperature that electrical equipment uses.
