Abstract
The utility model relates to an EVA (Ethylene Vinyl-Acetate) coating heating pipeline which comprises a heating pipeline body which mainly comprises an inner shell and an outer shell nested together. A heating coil is arranged between the inner shell and the outer shell and spirally winds the outer surface of the inner shell. The pipeline further comprises a cooling pipe, the cooling pipe and the heating coil wind the outer surface of the inner shell in parallel, and the cooling pipe is filled with cooling water. The cooling pipe is circulatory and is provided with a compressor and a condenser. A heat-insulating asbestos layer is arranged between the cooling pipe and the heating coil at an interval. According to the pipeline provided by the utility model, the problem of heat accumulation of the heating pipeline is solved by bringing residual heat on the heating pipeline by way of arranging the cooling water pipe on the heating pipeline and cooling the heating pipeline by cooling water in the cooling water pipe.
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 in the time of heating and melting in addition, when cooling curing, having good flexibility, anti-stress cracking and adhesive property, is a kind of comparatively desirable material that can be used for 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 the several aspects of casting molding processes control, 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 is mainly made up 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 be 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 is mainly made up 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.
