Embodiment
A kind of LED display that this embodiment provides, the difference of itself and prior art is the supporting substrate that it comprises, this supporting substrate as depicted in figs. 1 and 2, comprise: adopt the high strength frame 10 that carbon fibre composite makes and be inserted into the fin 20 that the drawing aluminum in described high strength frame 10 is made, and fin 20 is these supporting substrates of one-body molded formation with high strength frame 10.
Because carbon fibre composite has that quality is light, high strength, high-modulus, its density is about 1.2g/cm3, is less than 1/2nd of aluminum or aluminum alloy, but its tensile strength can reach 3.5GPa, or even 8 times of steel, modulus of elasticity is 230～430G Pa, is also much better than steel.There is good heat dispersion and draw aluminum, thereby the supporting substrate of this embodiment, in thering is excellent mechanical property, weight and greatly alleviating, also there is good heat dispersion, and moulding process is also comparatively simple, has good using value.
In preferred technical scheme, the interior upper and lower two parts symmetry of high strength frame 10 has been inserted into two fin 20, and the inner surface of fin 20 is smooth, for being close to LED display module (not shown), the heat producing while making the work of LED display module can pass to rapidly fin 20.Fin 20 outer surfaces are provided with multi-disc radiating fin 201, to increase its specific area, the heat on fin 20 are distributed to the external world efficiently.
Use bulk to draw aluminium radiator fin 20, mainly that the heat dispersion of considering carbon fibre composite does not have aluminium alloy good, therefore, here adopted the technical scheme of concentrated heat radiation, by Unit Design a certain ad-hoc locations on display module such as the larger driving chips of power consumption (caloric value), this position and fin 20 are just close to.Most heats that LED display module before supporting substrate sends are above sent to after aluminium heat sink 20, soon thermal radiation in air, thereby guarantee the normal serviceability of LED display module and permanent useful life.
In addition, as shown in Figure 3 and Figure 4, on supporting substrate, also remain with some other conventional architectural features, as there is a capillary groove 11 middle, also has reference column, embedded nut post, the through holes that are connected with display module etc., to guarantee the normal serviceability of supporting substrate.
The LED display supporting substrate of this kind of structure, the mode that adopts mould to be implanted into fin is made of one piece, and can adopt at present two kinds of moulding processs of comparative maturity on market to make.
Scheme one: RTM technique (also claiming resin transfer molding technique)
The first step: prepare carbon fiber wire or carbon cloth
According to the shape of goods, carbon fiber wire is woven into the shape of cloth or other appointment, there is the first cutting in place of through hole to portal.
Second step: lay in mould
The carbon cloth weaving (or other designated shape) is laid in mould regularly to then matched moulds.
The 3rd step: injection moulding
In mould, inject quantitative epoxy resin, epoxy resin immerses after carbon fiber completely, heating cure.
Scheme two: hot press forming technology
The first step: preparation preimpregnation cloth.Selected carbon fibre precursor is woven, form carbon cloth, immerse the epoxy resin of suitable types, form preimpregnation cloth.
Performance and the cost etc. of product as required, can select the carbon fibre precursor of appropriate size, has relatively high expectations as product thermal diffusivity, can consider with asphalt base carbon fiber; As required product fire-retardant, can select the epoxy resin of certain material in addition.
Second step: prepare supporting substrate thin slice.Preimpregnation cloth is carried out to processing of cutting and become suitable size, stamping-out punching is first carried out in the place of reserved through hole.
The 3rd step: moulding is prepared.The supporting substrate thin slice cutting in previous step is successively laid in mould, reinforces the position of boss and lay the supporting substrate thin slice of multilayer boss size, or thicken filler at the mid portion of lug boss position.
The 4th step: hot-forming.The supporting substrate thin slice laying in the 3rd step is carried out to high temperature hot pressing forming processes, and hot pressing temperature is set according to epoxy resin and the product performance selected.
The mode of drawing the preferred mould of aluminium radiator fin 20 to be implanted into is fixed on carbon fiber supporting substrate, and due to the size that the size of fin is a bit larger tham breach in base main body, therefore, while laying in mould, fin edge is to embed in carbon fiber interlayer.Another alternative is after substrate curing molding, fin to be adhered on substrate.
Compared with LED display in background technology, material and structure that this LED display supporting substrate is selected all improve to some extent, and heat radiation aspect also makes moderate progress.
Adopt the LED display beneficial effect of this supporting substrate to be:
1. the light feature of quality, is convenient to transport and shield the dismounting of body.
2. mechanical property and perfect heat-dissipating, guarantees serviceability and useful life that it is excellent.
3. moulding process is simple, has improved production efficiency.
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, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
