A flat plate type solar thermal collector which is mainly composed of a heat collector frame, a glass cover plate, a heat preservation plate, a heat absorption plate, and is characterized by further comprising a three-way medium outlet pipe, a medium inlet pipe, a branch flow channel outlet pipe, a branch flow channel coating plate and a branch flow channel inlet pipe; a plurality of corrugated heat absorbing plates and branch flow channel grooves are pressed on the heat absorbing plate, and the branch flow channel grooves are U-shaped grooves and are used for coating the branch flow channel outlet pipe and the branch flow channel inlet pipe; a plurality of branch runner outlet pipes and a plurality of branch runner inlet pipes are respectively communicated with the three-way medium outletpipe and the medium inlet pipe; the three-way medium pipe, the medium inlet pipe, the branch flow channel outlet pipe, the branch flow channel inlet pipe, the main flow channel, the medium outlet pipe connector and the medium inlet pipe connector are welded together in a brazing mode and are communicated with each other, and are pressed into a whole with the corrugated heat absorption plate and placed into the frame. The solar thermal collector has the characteristics of high heat collection efficiency, simple production process, low manufacturing cost, good pressure resistance, difficulty incorrosion and damage.
Description
[0001] Technical field [0002] The invention relates to a solar heating device, in particular to a flat-plate solar heat collector. Background technique [0003] At present, among the known solar heating devices, more and more flat-plate solar collectors are used, which are mainly composed of a heat absorbing plate of a collector, a cloth glass plate, an insulation layer and a support, and absorb solar energy for heating. It is divided into two types of structures: the overall blue film [or black chrome] + copper tube combination and the whole stainless steel plate stretch welded collector. Integral blue film [or black chrome] + copper tube combined heat collector, using a full-plate heat collector plate coated with a heat collecting film in advance to weld with copper tubes, the main channel and branch channel of the copper tube are connected by brazing, and the heat collecting film Absorb light and convert it into heat, heat the copper tube and the heat transfer medium in ...
