Description
[0001] The disclosure relates to the field of energy utilization, particularly to anew material
solar thermal collector.
[0002] With the development of economy and the progress of society, use of clean energy has
become an important link for today's social development and progress, and utilization of energy
is mainly utilization of solar energy.
[0003] A solar flat plate collector, as one of solar water heaters, has attracted more and more
attentions due to its reliable operation and easy combination with buildings.
[0004] The most common representation of the flat plate collector is water mist which is
formed by a fact that water evaporates when being heated and condenses into diffuse drops
when being cooled, and mainly comes from residual moisture, infiltrated moisture and damp
returning moisture. Some of these phenomena are caused by external factors and can only work
through internal reasons. The main internal reason is that a collector cavity has poor airtightness,
which results in the infiltration and damp returning of external moisture and dust. The invasion
of environmental factors can directly or indirectly cause secondary hazards through water.
[0005] Furthermore, in the solar flat plate collector, the thermal collection plate is a core
component whose performance directly affects the size of a thermal efficiency factor. There are
many manufacturers of solar heat absorbing plate cores at home and abroad, most of the
designed flat plate collectors adopt an all aluminum heat absorbing plate core, an all copper heat
absorbing plate core or a copper-aluminum composite heat absorbing plate core. Due to their
own materials, the above types of plate cores are easily oxidized, and have undesirable thermal
conductivity and fatigue resistance at high temperatures.
[0006] In summary, the solar flat plate collector in the prior art has the main problems: 1. due
to the objective factors of airtightness, moisture and dust easily enter the collector so as to affect
the heat collecting property; 2. the material of the collector sheet has the problems of easy
