太阳能热水器的型式很多。本文讨论的太阳能热水器乃直管式或瓦楞板式自然循环热水器,它是目前我国各地使用最广泛的型式之一,具有效率高、容水量大等许多优点。这种热水器通常由箱式采热器、水箱以及上升管、下降管等组成,采热器面向正南放置,并与水平成某一倾角。本文的计算是针对固定倾角和无负荷的运行工况。一九七五年五月,我们热力专业热工理论基础数学小组,为了使教育更好地为无产阶级政治服务,为社会主义的经济基础服务,并在教学中贯彻理论联系实际的原则,在进行《热
There are many types of solar water heaters. The solar water heaters discussed in this paper are straight tube or corrugated plate type natural circulation water heaters. It is one of the most widely used types in China and has many advantages such as high efficiency and large water capacity. This type of water heater is usually composed of a box type heat collector, a water tank, a rising pipe, a descending pipe, etc. The heat collector is placed facing south and has a certain inclination angle with the horizontal. The calculations in this paper are for fixed inclination and no load operating conditions. In May 1975, we warmly specialized in thermal theory basic mathematics group, in order to make education serve the proletarian politics better, serve the economic foundation of socialism, and implement the principle of combining theory with practice in teaching.
