Product DescriptionThe flat-plate solar collector is the
basic component of low-temperature heat utilization of solar
energy. The flat-plate solar collector is mainly composed of a
heat-absorbing plate, a transparent cover plate, an insulating
layer and a shell. The heat sink structure is basically in the
shape of a flat plate. When the flat-panel solar collector is
working, the solar radiation passes through the transparent cover
and is projected on the heat-absorbing plate, absorbed by the
heat-absorbing plate and converted into heat energy, and then the
heat is transferred to the heat-transfer medium in the
heat-absorbing plate , to increase the temperature of the heat
transfer medium, as the useful energy output of the
collector.Product Parameters StructureMaterialFlat plate

outlet AdvantagesThe flat plate collector has no vacuum
requirements, stable thermal performance, good integrity, and long
service life of the collector.In the flat plate collector system,
the water or working medium flows in the metal flow channel, and
the anti-cold and thermal shock performance is strongThe flat-plate
collector can be installed in a compact or gapless manner. While
producing hot water, it also has roof functions such as heat
preservation, heat insulation, and shading, which provides the
possibility to replace part of the roof structure.The flat plate
collector can be designed flexibly, and the size can achieve better
compatibility with the modulus of building materials and building
structureThe flat plate collector has good pressure bearing
performance, which can make the system run stablyFlat plate
collectors generally do not produce overheating and are resistant
to air exposure.Flat-plate collectors can be further improved in
specific engineering applications to make them more integral, with
greater advantages in terms of failure, life, and
investment.Company ProfileSince its establishment in 2002, Shandong
Longguang Tianxu Solar Energy Co., Ltd (hereinafter referred to as
"Tianxu") has always engaged itself in the R&D, production,
sales and service of high borosilicate glass tubes and new energy
products including solar water heaters, solar vacuum tubes, solar
heat collecting project, air source heat pump, photovoltaic
products, etc. Tianxu has 10 sets of electric furnaces, 70 sets of
solar vacuum tube production line and 3 sets of solar water heater
production lines. The annual output has reached one million tons of
