Polymer solar heat collector and manufacturing method thereof

Abstract

The invention discloses a polymer solar heat collector. The polymer solar heat collector comprises a cover plate and a frame, wherein a polymer heat-absorbing plate core is arranged at the interior of the frame; a polymer water tank is arranged on the back of the polymer heat-absorbing plate core; polymer heat preservation materials are filled between the frame and the polymer heat-absorbing plate core, between the polymer heat-absorbing plate core and the polymer water tank and between the frame and the polymer water tank; the polymer heat-absorbing plate core represents different colors; a plurality of heat-absorbing channels are formed in the polymer heat-absorbing plate core; a high-selectivity heat-absorbing coating capable of generating a plurality of absorption spectrums is arranged on each heat-absorbing channel; the cover plate, the polymer water tank, the polymer heat-absorbing plate core, the heat-absorbing channels and the polymer heat preservation materials are made of the polymer materials. The used materials of the polymer solar heat collector are light in weight and easy to process and form; the attractive appearance of the product is improved by the diversity of the colors of the polymer heat-absorbing plate core and the diversity of the self structural shape of the heat collector; the processing process is free of welding and free of screws and rivets; the polymer solar heat collector is convenient to process and high in production efficiency; the large amount of manpower is saved.

Description

technical field [0001] The invention relates to a heat collector, in particular to a polymer solar heat collector. The invention also discloses a manufacturing method of the polymer solar heat collector. Background technique [0002] The development of new energy and renewable clean energy is a common task faced by the whole world. In the development and utilization of new energy, solar thermal utilization has been successfully industrialized, which partially solves the problem of civil and industrial heat consumption, and produces huge economic and social benefits. [0003] The current medium and low temperature solar collectors mainly include all-glass vacuum tube solar collectors and flat plate collectors. The materials used for these two collectors are generally metal or glass. For example, a vacuum tube solar collector plate disclosed in a patent document with the application publication number CN102506508A includes at least two vacuum heat collector tubes parallel an...

AI Technical Summary

Problems solved by technology

[0004] 1) The materials used are metal and glass, which are relatively heavy, which brings inconvenience to transportation and installation;

[0005] 2) The assembly of these two heat collectors is relatively complicated, which requires a lot of labor and increases labor costs;

[0006] 3) The water tanks of these two collectors are generally placed above the heat-absorbing plate, which affects the appearance of the product and limits the diversification of the product

However, polymer collectors use polymer materials, and polymers generally do not have low emission characteristics, so it is necessary to study new selective absorption materials for polymer properties
