Description

Solar water heater is carried the enhancing device of warm water to the pipeline of biogas pool wall
Technical field
The present invention relates to the enhancing device of solar water heater, belong to technical field of new energy application to the pipeline conveying warm water of biogas pool wall.
Background technology
1970-1980; Because the restriction of scientific and technical condition at that time; Living standards of the people are not high, and how Chinese residents repacks the closing-sunning type water heater into empty petrol drum and be placed on the liquid water that tans by the sun under the sunlight in the thermotank, and the method efficient that this dependence sunlight directly shines the liquid water in the heat bucket is low, rapid heat dissipation, solarization hot water amount are little; Because practical value is not high, the closing-sunning type water heater suffers exit already.
Up to 1984, teacher's invention of Tsing-Hua University ' magnetron sputtering gradual change aluminium---nitrogen/aluminium solar selective absorbing coating ' made vacuum pipe solar water heater efficiently utilize solar energy to realize that large-scale production and commercial applications become possibility.The inventor of this patent in 2009, China's invention academician Miao TongChun are participated in the experience exchangement meeting of China invention association and organization to Beijing, hear that at the meeting the teacher of this invention vacuum pipe solar water heater of Tsing-Hua University introduces his painstaking efforts, the speech of having the courage to bring forth new ideas.
