带内集管的分体式太阳能热水器及其实验研究

为了实现太阳能热水器和建筑的结合,设计了一种分体式全玻璃真空管太阳能热水器。它由集热器、室内储水箱、上升管和下降管组成,其集热器的每根真空管内有一个分水管,分水管通过集箱内的集管与下降管相连。与已有的太阳能热水器相比,其分水管把真空管内的冷、热水流道分开,减少了冷热水流相互干扰,提高了热水器效率,同时实现了分体式太阳能热水器系统的自然循环。实验表明,带内集管的分体式太阳能热水器比不带内集管的分体式太阳能热水器有更高的效率。

A separated solar water heater with internal pipe and its experimental study

In order to implement to integrate solar water heaters and construction,an all-glass evacuated tubular separated solar water heater is designed in this thesis,which made up of a heater,an indoor tank,an ascent and a descent pipe.There is a internal pipe in every evacuated tube of the heater,which is connected with the descent pipe.Comparing with traditional separated solar heater,the internal pipe divides evacuated tubular into two rooms and decrease interference of water flow.At the same time the heater ca...
