二、太阳能热水器的结构及设计参数 太阳能热水器的主要组成部分是集热器和水箱,下面着重介绍亡的各组成部分的参数范围和基本的工艺要求: 1、集热器 集热器的具体结构如图5所示,其各组成部分分述于下。 (1)玻璃 玻璃采用普通平板玻璃.厚度d为3—6毫米,一般使用5毫米单层玻璃,如果冬季使用,或有其它特殊用途可采用双层玻璃,两层玻璃的间距为5～10毫米 玻璃表面要平整、清洁、透光性好。 玻璃一般用木条衬托,并用腻封严防漏气,边缝处覆盖金属或塑料板条,以防进水。玻璃和边框间留有5毫米的间隙,以免因热膨胀或框架变形等造成玻璃破烂。玻璃在框架上要垫防尘橡皮或毛毡,边缝用腻封。玻璃太大时厂面可高支撑点,玻璃如需搭接,切记顺水搭接,并腻封,严防进水,漏。
Second, the structure and design parameters of solar water heaters The main components of solar water heaters are collectors and water tanks, the following highlights the parameters of the death of the components and the basic process requirements: 1, the collector structure of the collector As shown in Figure 5, its components are described below. (1) Ordinary flat glass is used for glass glass, the thickness d is 3-6mm, 5mm single glass is generally used, and if it is used in winter or other special purpose, double glass can be used, the spacing between the two glass is 5 ~ 10 Mm glass surface to be smooth, clean, good light transmission. Glass is generally set off with wood, and use greasy seal to prevent leaks, side seam covered metal or plastic slats, to prevent water. Leave a 5 mm gap between the glass and the bezel to prevent the glass from being broken due to thermal expansion or deformation of the frame. Glass in the frame to pad dust rubber or blanket, side seams with greasy seal. When the glass is too large, the surface of the plant can be high supportive point, if the glass lap, keep in mind the lap, and tired of sealing, prevent water, leakage.
