平板太阳能的架构组成结构特性

平板太阳能热水器主要是由平板集热器、储水箱、水管、支架及配件等部分组成。平板集热器是平板热水器的关键部件,其热性能高低是衡量热水器好坏的重要指标。
The flat plate solar water heater is mainly composed of a flat plate collector, a water storage tank, a water pipe, a bracket and a part. Plate heat exchanger is a key component of the plate water heater, and its thermal performance is an important indicator to measure the quality of the water heater.
它主要包括涂有选择性吸收涂层的吸热板、透光材料盖板、保温层和外壳四大部分。当阳光透过玻璃盖板照在平板吸热板上时,其中大部分太阳辐射能为吸收体所吸收,转变为热能,并传向流体通道中的工质。通过自然循环或强迫循环,而将储水箱内的水加热。

It mainly includes four parts, which are heat absorbing plate with selective absorbing coating, cover plate, heat insulating layer and outer shell. When the sun shines in through the glass cover plate on the absorber plate, most solar radiation is absorbed by the absorber, changed into heat energy, and transmitted to the working fluid in the channel. Heat the water in the tank by natural circulation or forced circulation.

吸热板的材料国外基本上都用铜和不锈钢,国内已经大量采用铜材、铝合金、钢材、镀锌板,沿海水质较差的地区,则可用塑料或玻璃来替代。因为金属表面的反射率高,吸收率低,为了增强吸收效果,必须在金属表面也即吸热板上制备涂层。
The absorber plate materials abroad basically with copper and stainless steel, copper, steel, galvanized plate, Aluminum Alloy has been widely used in domestic coastal areas, poor water quality, can be used to replace the plastic or glass. Because of the high reflectivity of the metal surface, the absorption rate is low, in order to enhance the absorption effect, it is necessary to prepare the coating on the metal surface.
按制备工艺不同,可将涂层分为电镀涂层、电化学转化涂层、真空镀膜涂层和涂料涂层四种主要形式。因为集热器周围是空气,所以当集热器的吸热板在转变太阳辐射能量为水的热能时,也向周围环境散失热量,这就使太阳辐射能量不能全部转化成水的热量。
According to the different preparation technology, the coating can be divided into four main types, which are electroplating coating, electro chemical conversion coating, vacuum coating coating and coating coating. Because the collector is surrounded by air, so when the heat absorbing plate collector in the transformation of solar energy into water, and the heat loss to the surrounding environment, which makes the solar radiation energy cannot be completely converted into the heat of water.
为了减轻这部分能量的损失,在吸热板上面安装透光材料盖板,使盖板透过可见光而不透过远红外线,从而减少能量散失,更有效地提高吸热板和水的温度。优质透光材料盖板对热水器的效率及寿命有很大影响。
In order to reduce this energy loss, the installation of transparent material in the absorber plate above the cover plate, the cover plate through the visible and not through the far infrared, thereby reducing energy dissipation, effectively improve the heat absorbing plate and the temperature of the water. The cover plate of high quality light transmitting material has great influence on the efficiency and life of the water heater.
