  1、集热元件-真空管技术参数规格:管径:47mm、58mm。管长:1200mm、1500mm、1600mm、1800mm、1900mm、2000mm、2100等等。
1, the vacuum tube heat collection element - Technical Specifications: diameter: 47mm, 58mm. Length: 1200mm, 1500mm, 1600mm, 1800mm, 1900mm, 2000mm, 2100 etc..
目前集热效果的更好的是AL---N/AL真空溅射选择性镀膜,其吸收率≥0.95,发射率ε≤0.6,热损系数小,采用高硼硅3.3特硬玻璃,硬度高,抗冲击力强。济南力诺瑞特太阳能
At present, the heat collecting effect is the best AL---N/AL vacuum sputtering selective coating, its absorption rate is more than 0.95, the emissivity epsilon = 0.6, coefficient of heat loss is small, made of high borosilicate 3.3 hard glass, high hardness, strong anti impact force.
2、保温材料性能特点及技术参数:
2, insulation performance characteristics and technical parameters of material:
保温材料的好坏直接关系着太阳能热水器热效率和晚间清晨的使用,在寒冷的东北尤其重要。目前较好的保温方式是进口聚氨脂保温,若配料、工艺、环境、温度不适,也会造成发泡不均或泡孔过大、工质缓慢漏失保温性逐渐下降的后果,这就需要厂家有专门的发泡机械、标准化模具和较高的工艺技术水平。
Thermal insulation material is directly related with the solar water heater thermal efficiency and the use of evening morning, especially important in the cold northeast. At present, good insulation is imported polyurethane insulation, if the ingredients, craft, environment temperature, discomfort, can also cause foaming or uneven bubble is too large, medium slow leakage insulation declined consequences, which requires manufacturers have special foaming machine, standard mold and a higher technology level.
3、聚氨酯保温层厚度:50mm、60mm、70mm等,闭孔率要达到98%以上,并经过高温熟化处理。
3, polyurethane insulation layer thickness: 50mm, 60mm, 70mm and so on, obturator rate to reach more than 98%, and after high temperature aging treatment.
4、水箱内胆:水箱内是储存热水的重要部分,其用料强度和耐腐蚀性至关重要。优质的选材应是进口SUS304-2B不锈钢板材,厚度在0.5mm或以上,采用亚氩气保护,高频自动焊接,可提高钢板在各种水质或各种环境耐腐蚀性能。
4, water tank: the water tank is an important part of storage water, the material strength and corrosion resistance is very important. High quality materials should be imported SUS304-2B stainless steel sheet, thickness in 0.5mm or above, using sub argon, high frequency automatic welding, can improve the corrosion resistance of steel in various water or various environmental.
5、水箱外皮:闪闪发亮的不锈钢板耐腐蚀性较差,且易造成光污染,大的太阳能热水器厂家已不再采用,一般使用质量较好、耐腐蚀性较高的彩钢板作水箱外皮。
5, tank closure: poor corrosion resistance of stainless steel plate shiny, and easy to cause light pollution, solar water heater manufacturers no longer use, color steel plate in general use good quality, corrosion resistance is higher for tank closure.
6、支架:强度高、耐腐蚀性好的支架材料为铝型材,应采用螺栓连接,利于运输安装,抗风性能强。
6, support: high strength, corrosion resistance good scaffold material for aluminum profile, should be connected with bolts, convenient transportation and installation, strong wind resistance performance.
7、反光板:好的反光板应是采光效率高、反射效率高,把更多的光线反射到真空管上,增加真空管的吸热效率。
7, the reflecting plate: reflective plate should be good lighting high efficiency and reflection efficiency is high, the more light into the vacuum tube, increase the heat efficiency of the vacuum tube.
