Abstract
The invention relates to an EVA (ethylene-vinyl acetate copolymer) adhesive film heating pipeline. The EVA adhesive film heating pipeline comprises a heating pipeline and a cooling pipe, wherein the heating pipeline is mainly formed by an inner shell and an outer shell, which are nested together; a heating coil is arranged between the inner shell and the outer shell and winds the outer surface of the inner shell spirally; the cooling pipe and the heating coil wind the outer surface of the inner shell in parallel; the cooling pipe is filled with cooling water, is circular and is provided with a compressor and a condenser; the cooling pipe and the heating coil are separated by an insulating asbestos layer. The EVA adhesive film heating pipeline has the beneficial effects that the cooling water pipe is arranged on the heating pipeline and the cooling water in the cooling water pipeline is cooled to bring away excess heat on the heating pipeline, thus solving the problem of heat accumulation on the heating pipeline.
Description
Technical field
The present invention relates to a kind of water back, be specifically related to a kind of EVA glued membrane water back.
Background technology
If solar cell is directly exposed in air, its photoelectric transformation efficiency can decline very soon, loses practical value.Therefore, the research and development of the encapsulation material of solar cell are just very important.For reaching the object being isolated from the outside; adopt transparent, light aging resisting, adhesive property good, can bear atmosphere and change and there is flexible ethylene-vinyl acetate copolymer (EVA) glued membrane solar battery sheet is sealed; and be bonded together with levels protective material, form solar module.
EVA is a kind of typical random macromolecular compound, in its molecular structure, the irregular arrangement of substituting group on strand, in strand, the configuration of asymmetric carbon atom is not identical yet simultaneously, arrange also irregular, therefore it be that a kind of crystallinity is less, polarity and the higher material of pliability, it has good wellability when heating and melting in addition, during cooling curing, there is good flexibility, anti-stress cracking and adhesive property, be a kind of comparatively desirable can be for the material of solar cell package.
What EVA film forming adopted is extrusion forming process, and whole production line generally includes mixing plant, extrusion equipment, film pressing device, trimming unit and retractable volume equipment, completes batch mixing, material loading, extrudes, calendering, trimming, winding process.Determine will have of end product quality: raw material and formula, hot-melt extrusion process, and casting molding processes is controlled several aspects, and in casting molding processes process, environment temperature and humidity is also an important step, suitable humidity and stable temperature, the Shen of drawing that can reduce film is out of shape, the tension force of controlling diaphragm.
At present, in EVA production process EVA micelle in water back by the colloid of melt into molten condition.Water back, normally by electrical heating, easily forms heat build-up in electrical heating, is difficult for temperature to control the quality that all can affect EVA glued membrane too high or too low for temperature.
Summary of the invention
The technical problem to be solved in the present invention is: propose a kind of EVA glued membrane water back of being convenient to regulate temperature.
The present invention is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of EVA glued membrane water back, comprise water back, described water back mainly consists of the inner casing nesting together and shell, between described inside and outside shell, be provided with heater coil, the screw type outer surface that is wrapped in described inner casing of described heater coil, also comprise cooling tube, described cooling tube and described heater coil are wrapped in the outer surface of described inner casing side by side, in described cooling tube, are filled with cooling water.
Further, described cooling tube circulates, and described cooling tube is provided with compressor and condenser.
Further, described cooling tube and described heater coil is interval with insulation asbestos layer.
The invention has the beneficial effects as follows:
The present invention, by cooling water pipe being set on water back and the cooling water of cooling water pipe the inside being lowered the temperature, takes away the problem of the waste heat solution water back heat build-up on water back.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, EVA glued membrane water back of the present invention is described further.
Fig. 1 is the structural representation of EVA glued membrane water back in embodiment.
The specific embodiment
Embodiment
Shown in Fig. 1, EVA glued membrane water back in the present invention, comprise water back, described water back mainly consists of the inner casing 1 nesting together and shell 2, between described inside and outside shell 2, be provided with heater coil 3, the screw type outer surface that is wrapped in described inner casing 1 of described heater coil 3, also comprises cooling tube 4, described cooling tube 4 and described heater coil 3 are wrapped in the outer surface of described inner casing 1 side by side, in described cooling tube 4, are filled with cooling water.
Described cooling tube 4 circulates, and described cooling tube 4 is provided with compressor 5 and condenser (not shown).
Described cooling tube 4 and described heater coil 3 be interval with insulation asbestos layer.
The present invention, by cooling water pipe being set on water back and the cooling water of cooling water pipe the inside being lowered the temperature, takes away the problem of the waste heat solution water back heat build-up on water back.
The above-described embodiment that is not limited to of the present invention, all employings are equal to replaces the technical scheme forming, and all drops in the protection domain of requirement of the present invention.
