A kind of polymer solar heat collector and its manufacturing method

Abstract

The invention discloses a polymer solar heat collector, which comprises a cover plate and a frame, a polymer heat-absorbing plate core is arranged in the frame; a polymer water tank is arranged on the back of the polymer heat-absorbing plate core; the frame and the polymer absorb heat The plate core, the polymer heat-absorbing plate core and the polymer water tank, the frame and the polymer water tank are filled with polymer insulation materials; the polymer heat-absorbing plate core can present different colors; the polymer heat-absorbing plate core is equipped with There are several heat-absorbing channels with highly selective heat-absorbing coatings that can generate multiple absorption spectra; cover plate, polymer water tank, polymer heat-absorbing plate core, heat-absorbing channels and polymer The insulation materials are all made of polymer materials. The materials used in the present invention are light in weight and easy to process and shape; the diversity of the colors of the heat-absorbing plate core and the diversity of the structural appearance of the heat collector itself improve the aesthetics of the product; the processing process does not require welding, screws and rivets , processing is convenient, save a lot of labor, high production efficiency.

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 heat collecting plate disclosed in the patent document with the application publication number of CN 102506508 A includes at least two vacuum heat collecting tub...

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
