本家用太阳开水——热水器是一种适于广大城乡住户推广应用的新型太阳热水器。其主要技术特点是在集热板和透明盖板之间,设置了能有效抑制有限空气层内的自然对流和显著减少黑吸热板的红外辐射热损失的蜂窝结构。同时,对循环水箱和联管回路系统作了合理的设计与配置,使整个装置系统的热性能有较大提高,运行温度可达100℃,扩大了应用范围、功能和使用时间。 结构特点:减小集热板和透明盖板间的自然对流换热系数h_(c2)和辐射换热系数h_(r2)有效的方法。是在集热板和透明盖板之间的封闭空气层,设置形状和尺寸(高径比L/D)适当的透明蜂窝结构。这样,就
The home with the sun water - water heater is a suitable for the majority of urban and rural households promote the use of new solar water heaters. The main technical feature is that a honeycomb structure is provided between the heat collecting plate and the transparent cover plate to effectively suppress the natural convection in the limited air layer and significantly reduce the infrared radiation heat loss of the black heat absorbing plate. At the same time, the design and configuration of the circulating water tank and the combined circuit system are reasonably designed so that the thermal performance of the entire system is greatly improved. The operating temperature can reach 100 ° C, which expands the application range, function and usage time. Structural features: to reduce the collector and the transparent cover between the natural convection heat exchange coefficient h_ (c2) and radiation heat transfer coefficient h_ (r2) effective method. Is a closed air layer between the collector plate and the transparent cover plate, provided with a suitable transparent honeycomb structure of the shape and size (height-diameter ratio L / D). That’s it
