Abstract
The present invention relates to a radiator and a preparation technology thereof. An insert injection molding radiator comprises heat conduction pipes, one ends of the heat conduction pipes are attached to a heating body, and the other ends are embedded in the radiating fins. The radiating fins are formed by integrally injection molding the heat conduction plastic cement molds at one ends of the heat conduction pipes, and a contact part between the heating body and the heat conduction pipes is packaged as one by a heat conduction plastic cement to form a fixing part, and the fixing part is the heat conduction plastic cement of the contact part formed by integrally injection molding the heat conduction plastic cement molds between the heating body and the heat conduction pipes. The production technology steps of the above insert injection molding radiator comprise fixing one ends of the heat conduction pipes together with a heating body jig, then putting one ends of the heat conduction pipes and the jig in the fastening positions of an injection mold, carrying out the mold assembly, filling in the heat conduction plastic cement of a fusion state, maintaining pressure, cooling and demolding. According to the present invention, the conventional metal materials are substituted partially, the processing technologies, such as machining, electroplating, welding, etc., are saved, the manufacture cost is reduced, and the weight is light.
Description
Technical field
The present invention relates to and relate to a kind of radiator, also relate to its preparation technology.
Background technology
Conventional radiator is generally metal material, such as aluminium alloy heat radiator, Cu and Al combination radiator.Heat conductive plastic material, it is the metal oxide being added with thermal conductivity in common plastic cement, the plastic composite material that graphite fibre or carbon fiber etc. are composited, started commercially to be used widely, its efficient thermal conductivity can replace part with the radiator of aluminum profile extrusion, shell etc.Its excellent heat conductivility and low-gravity feature, not only make the heat radiation of electronic product be protected, and can increase portability and the cost of transportation of product simultaneously.In addition, heat conduction plastic cement, by injection mo(u)lding, can shorten production cycle increase production capacity.Such as application number 201420040801.6, name is called " LEDbulb lamp ", application number 201320708820.7, and name is called " high-power LED (Light-Emitting Diode) lamp radiator ", and heat conduction plastic cement is all assemble with other metal partss as after independent parts independence injection mo(u)lding again.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of insert injection moulding radiator, and heat conduction plastic cement is directly injected into integrally with metal material, and provides its preparation technology.This law is applicable to the heat radiation being applied to computer or game machine, significantly can reduce metal material, thus saves the processing technologys such as machining, plating, welding, reduces cost of manufacture.
Technical problem to be solved by this invention is achieved by the following technical programs:
A kind of insert injection moulding radiator, comprise heat pipe, described heat pipe one end fits in heater, and the other end is embedded in radiating fin, and described radiating fin is in the radiating fin of heat pipe one end by injection moulding during heat conduction plastic cement mould integrated injection molding.
Further, the contact site heat conduction plastic cement encapsulating between described heater and heat pipe is integrated, and forms fixed part.
Further, described fixed part is by the heat conduction plastic cement of the contact site of injection moulding between heater and heat pipe during heat conduction plastic cement mould integrated injection molding.
A kind of above-mentioned insert injection moulding radiator production technology, step comprises: be fixed together in one end of heat pipe and heater tool, then it put into the screens of injection mould together with tool, matched moulds, inserts the heat conduction plastic cement of molten condition, pressurize, cooling, the demoulding.
Further, after the demoulding, heat pipe is bent into required shape.
The present invention has following beneficial effect:
Part of the present invention instead of the metal material such as traditional copper, aluminium, eliminates the processing technologys such as machining, plating, welding, reduces cost of manufacture; Compare weight metal and want light a lot, density is at 1.5 ~ 1.8g/cm
3, in structural design, the degree of freedom is very large, need not worry the constraint of metal machining.The rigidity of Shooting Technique formability of the present invention, bendability and metal combines supplementary mutually, firmly can make complicated exquisite metallo-plastic integration product, the formed combination in advance of multiple inserts, and the engineering after product unit is combined more is rationalized.For the elasticity of flexure products formed on rigidity products formed, rubber seal backing plate, after integration product is made in injection mo(u)lding on matrix, the complex job of arrangement sealing can be saved, the automation of rear operation be combined easier.
Because the present invention is the material of melting and the joint of metal insert, compared with the press-in method of forming, metal insert gap can be designed narrower, and the shaping reliability of joint product is higher.Production technology of the present invention adopts the combination of vertical injection molding machine and manipulator, inserts product arranging-in-row device etc., and insert-molding engineering mostly can realize automated production.
