The utility model provides the heat dispersion of high mobilephone terminal customer graphite thermal film product provides effectual heat dissipation solution for the customer.
Description
Technical field
The utility model belongs to graphite radiating film formed product assembling field, particularly relates to a kind of graphite radiating hymenotome line exhaust apparatus.
Background technology
When graphite radiating film assembling product pastes, because graphite radiating membrane material is ultra-thin and partially soft, graphite radiating film product and binding face easily produce bubble, bulge, the bad phenomenon such as fold, traditional solution opens numerous ￠ 2mm small sircle hole to be exhausted on graphite radiating film surface, so both increases graphite radiating film at processing cost and yield, have great impact again on the radiating effect of graphite radiating film own.
Existing graphite radiating film surface adds the problem of steam vent:
1. terminal client is more and more higher to the cooling requirements of body own, reaches increase radiating effect to strengthen graphite radiating membrane area, increases cost;
2. because increasing exhaust hole on graphite radiating film surface, cause heat dissipation film efficiently radiates heat area to reduce, radiating effect reduces about 5%;
3., when the assembling of graphite radiating film pastes, easily there is bubble in small sircle hole periphery, alice bad phenomenon;
4. graphite radiating film aperture exhaust production working (machining) efficiency is low, yield is low, and main bad phenomenon is that product waste material is many;
5. arrange aperture waste material die cost high; Comprehensive the problems referred to above, traditional aperture exhaust scheme cost is high, and production efficiency is low, affects heat dispersion.
Utility model content
In order to solve above technical problem; the utility model provides a kind of graphite radiating hymenotome line exhaust apparatus; comprise diaphragm, dielectric film, graphite, double faced adhesive tape and release film from top to bottom successively; described graphite is provided with heat dissipation film; described heat dissipation film is provided with the cutter line for dispelling the heat; when described heat dissipation film pastes, air is discharged by described cutter line.
Preferably, described cutter line is 24.
Preferably, described diaphragm, dielectric film, release film and heat dissipation film adopt PET material, and described double faced adhesive tape adopts acrylic acid series adhesive.
The thickness of described diaphragm is 0.05mm, and the thickness of dielectric film is 0.01-0.03mm, and the thickness of graphite is 0.025mm, and the thickness of double faced adhesive tape is 0.015-0.03mm, and the thickness of release film is 0.075mm.
Preferably, the distance between described cutter line is 10mm, and the length of cutter line is 10mm.
The utility model adopts above technical scheme, its advantage is, it is better that this exhaust scheme is used in the exhaust effect when graphite radiating film product pastes, the radiating requirements of terminal client for graphite products can be better met again, more effectively solve graphite radiating film product and paste exhausting problem in process, thus improve graphite radiating film product Appropriate application and heat dispersion, reduce processing cost and add product yield.

Embodiment
Below in conjunction with accompanying drawing, preferably embodiment of the present utility model is described in further detail:
As shown in Figure 1, graphite radiating hymenotome line exhaust apparatus comprises diaphragm 10, dielectric film 11, graphite 12, double faced adhesive tape 13 and release film 14 from top to bottom successively.
As shown in Figure 2; traditional graphite radiating film product is made up of 5 materials usually; graphite 12 one side is covered double faced adhesive tape 13; one side covers dielectric film 11 in addition; add in double faced adhesive tape 13 face and cover one deck release film 14 backing; add in dielectric film 11 face and cover layer protecting film 10, diaphragm tears hand 15 and can tear, and is used for preventing product scuffing, fingerprint etc.
Tradition aperture exhaust structure product, shaping by mould punching products, as Fig. 3 and 4, known, product 20 is 10mm by 62 gaps, diameter is that 2mm aperture is formed, diameter to be 4mm aperture 21 and diameter be 5mm aperture 22 is for location, and discharge air by aperture when product pastes, aperture waste material is many, not easily waste discharge, aperture affects heat radiation too much;
As shown in Figure 5, product exhaust is used for by punching cutter line, in graphite radiating film product, the subregion tangent line that 24 length and gap are 10mm replaces small sircle hole, heat dissipation film no waste mine, produce air to discharge from tangent line when fitting assembling, cutoff tool line length is short can be uniformly distributed with product size size.
24 cutter lines 30 act on product and paste final vacuum herein, and cutter line length is short suitably can be adjusted according to product structure and size, and the diameter also comprised for locating is the aperture 31 of 4cm, and the diameter for locating is the aperture 32 of 5cm.
Fig. 6-8 is for mobile phone temperature rise test cutter line exhaust structure product heat radiation test (24 bar 10*10mm cutter line), testing tool: thermal imaging system FLUKETi100.
Test condition: normally use at mobile phone, do heat radiation test in 20 minutes .40 minute .60 minute when room temperature is 25 DEG C respectively, test result is respectively: 38.48 DEG C, 38.86 DEG C, 39.03 DEG C, therefore known, this device is used on mobile phone, and radiating effect is obvious.
Following characteristics is had by above-mentioned exhaust apparatus:
1. improve the heat dispersion of mobile phone terminal client graphite radiating film product, for client provides effective Cooling Solution;
2. effectively can solve to meet when graphite radiating film assembling product pastes and produce the problems such as bubble is bad;
3. graphite radiating film product is when front end machine-shaping, both reduces die cost, can effectively improve product yields again, and yield improves about 10% than original.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection range of the present utility model.
