Abstract
The utility model relates to a graphite boat used for producing radiating films. The graphite boat comprises a lower bottom plate 1, supporting posts 3, an upper cover plate 2 and a screw cap 4, wherein the supporting posts 3 are double-ended threaded rods and arranged between the upper cover plate 2 and the lower bottom plate 1 as support between the two plates. One end of each of the supporting posts 3 is directly fixed on the lower bottom plate 1 by threads, the other end of each of the supporting posts 3 is fixed with the upper cover plate 2 by a nut 4. 6-8 supporting posts 3 are arranged between the upper cover plate 2 and the lower bottom plate 1. The upper cover plate 2 and the lower bottom plate 1 are circular and can be made of a graphite material. Square through holes which are symmetrically distributed are arranged on the upper cover plate 2. The graphite boat used for producing radiating films has the advantages of being simple in structure, convenient and practical, and capable of continuously producing high-quality artificial graphite radiating films in batch on a large scale.
Description
Technical field
The utility model relates to the vessel that hold object in a kind of thermal treatment process, particularly a kind of graphite boat for the production of heat dissipation film.It is a kind of auxiliary means for serialization scale operation heat dissipation film.
Background technology
Along with the high speed development of microelectronics industry, electronic product, LED etc. are constantly to high-power future development, and unicircuit high speed, densification increasingly, there will be increasing heating problem, and product power is reduced, and the lost of life, reduces its reliability.Therefore be badly in need of development highly heat-conductive material, solve structure heat dissipation problem.
At present, various heat sink materials are widely used.For example metallic substance has good heat conductivility, as copper, aluminium etc., utilizes these metal scatterers to be widely used.But weight metal is large, not corrosion-resistant, and after there is oxidation, its heat dispersion can reduce greatly.Meanwhile, there is in recent years the miniaturization of the various device of the heater members such as semiconductor element mounted thereon, and the tendency of the thermal value of these parts increase, use metal to be restricted as the space of the parts of heat sink material.
Thereby, pay attention to as thermal conductor the electrographite film that thermodiffusion performance is good always.Electrographite film is that to form in laminate structure, its face thermal conductivity by carbon very high, and density gently arrives 1.0-2.0g/cm
3left and right, can spread rapidly heat that heating position produces to reduce device temperature, also has the feature of flexibility as film, is therefore expected to heat transfer device material or radiator material as narrow place or the place that need to process through gap always.
Electrographite film is to carry out carbonization and greying thermal treatment obtains by the polymeric membrane of Dui polyoxadiazole, polyimide, polyphenylene vinylene, polybenzimidazole, polybenzoxazole, polythiazole or polymeric amide etc. under the inertness such as argon gas, helium atmosphere or under decompression.The plane thermal conductivity of the rostone ink film that degree of graphitization is high can reach 1600 to 1900W/mk, and perfectly the thermal conductivity of the in-plane of rostone ink film can reach 2400 W/mk in theory.The application of rostone ink film is very extensive, can be applicable to the fields such as great power LED, high heating electronic product, microelectronic integrated circuit encapsulation, motor, automobile, cable and aerospace.Rostone ink film will be made very important contribution towards thinner, lighter, integrated future development for above-mentioned electronic product.
At present all unexposed complete manufacturing process of patent of numerous electrographite films, and the manufacturing process of rostone ink film have diversified feature, are not limited to a kind of form.The container that carbonization and graphitizing process load polymeric membrane is graphite boat.
Summary of the invention
The technical problems to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of graphite boat for the production of heat dissipation film is provided.Simple in structure, be convenient to make, can make internal atmosphere even density distribute, improve product quality stability.
Technical solution of the present utility model is, comprises lower shoe 1, pillar stiffener 3, upper cover plate 2 and nut 4, and pillar stiffener 3 is two start screw bar, is located between upper cover plate 2 and lower shoe 1; 3 one of pillar stiffeners are directly fixed on lower shoe 1 by screw thread, and pillar stiffener 3 other ends fix by nut 4 and upper cover plate 2.
Between upper cover plate 2 and lower shoe 1, be provided with 6-8 root pillar stiffener 3.
Upper cover plate 2 and lower shoe 1 are rounded.
Upper cover plate 2 is provided with symmetrical square through hole.
The utility model and prior art compare, possess beneficial effect be that simple in structure, convenient and practical, in batches continuous large-scale be produced high-quality electrographite heat dissipation film.The height that can adjust according to the quantity of film pillar stiffener, meets the production of the film of different quantities; While unloading boat after thermal treatment, can make easily boat separate with heat dissipation film, and mounting or dismounting are convenient, avoid the mode of pounding of striking adopting in order to separate boat and heat dissipation film, extend the work-ing life of graphite boat, in use because damage is scrapped, a situation arises to have reduced in a large number graphite boat, greatly reduces production cost.Produce heat dissipation film thermodiffusion performance good, bend resistance is capable strong, can solve the heat dissipation problem of electronic product element.
