Qujing solar energy projects currently on the market a lot of flat plate collectors, though many styles, but it works basically the same, the typical structure provided by the heat, transparent cover, composed of four parts insulating layer and the housing. That reference, also known as the endothermic heat stripping or the absorbent body, the structure of the combination of collector plates and the collector of the working fluid through the flow conduit, which is to absorb solar radiation is converted to heat energy to the working fluid of the heat collecting member conduction. So it is a solar flat plate collector of the key components of its characteristics: 1, good surface properties of spectrally selective solar collector plate surface radiation absorption rate, low heat radiation. 2, with excellent heat transfer design. 3, good sealing performance, can work under pressure. 4, with the collector working fluid has good compatibility. 5, on the environment with good weather resistance. 6, Qujing aesthetic appearance of solar energy projects in line with the requirements of the public. General Titus is hot metal production, such as copper, aluminum, stainless steel, or copper and aluminum in line with the structure of the individual but also the use of special plastic production, surface coating mention that hot black absorbing coating or create spectrally selective absorbing coating.
