技术领域
本发明公开了真空玻璃产业中的一种创新产品,主要适用于在冬季对房屋、厂房、库房等的保暖,以及对养殖业的圈舍或者种植业的温室大棚提供热能和保温,或者满足对粮食、食品、药品、果蔬等加工业产品的烘干或者仓储的需求等等。
背景技术
目前,在我国随着科学技术的发展,尤其是在真空玻璃产业中,各种具有节能、环保功效的真空玻璃产品相继问世,并且品种越来越多,不仅在一定程度上对促进人民生活水平的提高和生产力的发展起到了积极作用,而且也基本满足了生产生活日用品及节能环保市场的需求。但是,在真空玻璃产业中,在太阳能利用这个问题上,却有很多产品存在缺陷和不足之处,因此有必要对其进行改革与创新,以最大限度地满足市场需求。

具体实施方式
下面结合附图对本发明最佳实施方案进行详细描述。
关于真空玻璃的定义、优点及作用:真空玻璃由两块平板玻璃构成,玻璃板之间用高度为0.1~0.2mm的支撑物3呈矩阵排列隔开,四周使用玻璃焊料将两片玻璃封接起来,其中一片玻璃上留有抽气孔,真空排气后用金属片将抽气孔封住形成真空腔。真空玻璃的原片可以用普通玻璃,也可以用钢化或半钢化玻璃。为了提高热工性能,通常选用一片低辐射膜玻璃;为了提高安全性,也可以将真空玻璃通过合中空或夹胶的方式与另外一片玻璃组合成“复合真空玻璃”。真空玻璃具有传热系数低,隔音性能好,应用广泛等优点,能够起到保温隔热、防止结霜露、节能降耗、隔音降噪的作用。
真空玻璃所选用的封边材料是广泛应用于电子显像管、VFD、PDP等电真空器件的玻璃钎焊料,熔封后形成玻璃态,本身气体渗透率和放气率都很低,经过理论与长期的实践,证明其有非常优异的真空封接性能。
一种具有集热功效的真空玻璃,其特征在于在该真空玻璃本体1上一块原片玻璃内侧壁面即第三面上喷涂固化有太阳能选择性吸收涂层4。
上述该真空玻璃本体1的制作和技术原理如下:采用两片平板玻璃中间有支撑物3,该支撑物3可以采用硅质材料或金属材料,可以做成三角形、圆锥形、圆柱形、半球形、陀螺形等等。首先,采用镀膜机在其中一片平板玻璃的壁面上喷涂固化有太阳能选择性吸收涂层4,然后与另一片平板玻璃叠置在一起,有涂层的一面作为下片玻璃6的内侧壁面即第三面与上片玻璃2的四周边用硅焊剂密封熔焊的方法密封,两片玻璃的间距为0.1~0.2mm,在上片玻璃2一角处开一个小孔作为玻璃排气孔8,经排气孔8真空排气封结,即采用抽真空、封口等工艺完成,使两层玻璃中密封形成高真空空间,形成一种具有集热功效的真空玻璃成品。做到一种全硅质无机熔焊密封实用新型真空玻璃。真空度可达到8×10-6Pa。
处于真空状态下的该真空玻璃本体1具有高吸收率和卓越的传热性能,传热不需工质相变,靠分子热运动,传热快,传热效率高,可在严寒、低太阳辐射下使用,适合多种气候,特别在多云、辐射强度低的情况下,启动传热快,最大限度地实现光热转换,光热转换率高达94%。
该真空玻璃本体1的玻璃材料应精选优质的3mm的特硬高硼硅玻璃,其最大可以抵御直径3cm冰块从30米高处自由落体运动的冲击,因此抗冰雹能力非常强,具有抗冲击强度大,耐热性强的优点。
因为在该真空玻璃本体1的内侧壁面即第三面上镀有磁控溅射太阳能选择性吸收涂层4,经太阳光照射,光子撞击太阳能选择性吸收涂层4,将吸收的太阳能转换成热能。由于在该真空玻璃本体1内没有空气对流,起到真空绝热的作用,所以后壁面即第四面上的热能就会源源不断地输出并把热量散发到室内。在严寒的冬季里室温可达20℃以上,输出端的温度可以达到250℃。因为在该真空玻璃本体1内既没有水也没有空气,所以这种良好的热性能即使在北方寒冷地区的冬季也不会受到丝毫影响。由此可见,在一个冬季里一栋楼房会节省很多能源费用,那么推而广之,在全国乃至全世界又会节省多少能源费用呢?如果再把全世界养殖业的圈舍和种植业的温室大棚也包括在内,那么一个冬季下来,还会节省更多的能源费用!因此可以说,本项目产品的社会效益和经济效益十分可观。
太阳能选择性吸收涂层4采用的是目前国际领先的干涉镀膜技术,可以有效提高该真空玻璃本体1的集热能力。
在此,对该真空玻璃本体1的规格,形状不作限定,可以不拘一格;对支撑物3使用的材料及规格、形状也不作限定,可以不拘一格。
在使用时,结合实际情况和需要,选择使用相关规格或形状的该真空玻璃本体1,采用常规或特殊技术手段把该真空玻璃本体1固装在需要它的地方。
