Problems solved by technology

However, at present, the biggest problem in using polymer materials to manufacture solar collectors is that polymer materials cannot selectively absorb sunlight. Coating methods such as magnetron sputtering technology, sol-gel method, electroplating method, coating method, vapor deposition method, etc. are difficult to achieve on polymer substrates

Embodiment 1

[0029] A kind of plate type solar heat collector of present embodiment composite polymer material, as figure 1 or figure 2 As shown, the plate solar collector is made of polymer materials, including the solar heat absorbing core plate 3, the transparent cover plate 1, the opaque bottom plate 4 and the end sealing beam 2, wherein the transparent cover plate is compounded on the solar heat absorbing core plate At the top, the opaque bottom plate is compounded under the solar heat-absorbing core plate, and the end-sealed beam is compounded on the longitudinal end faces of the solar heat-absorbing core plate, transparent cover plate and opaque bottom plate, sealing the solar heat-absorbing core plate, transparent cover plate and opaque bottom plate vertical space.

[0030] Among them, the manufacturing method of the solar heat absorbing core board is: using a mixing and extruding equipment with a strong mixing and dispersing effect (such as a blade extruder or an eccentric rotor...

Embodiment 2

[0038] In this embodiment, a kind of polymer material composite plate solar heat collector is compared with Embodiment 1, and its difference is that: the solar heat absorbing core plate is a hollow plate with a longitudinal medium channel (such as Figure 4 shown), the manufacturing method is: using a mixing and extruding equipment with a strong mixing and dispersing effect (such as a blade extruder or an eccentric rotor extruder, etc.) A polymer material that selectively absorbs solar energy is made in the matrix (the mass content of the solar selective absorber in the polymer is generally about 0.01% to 30%), and then manufactured by extrusion, injection molding, etc. into a hollow sheet with longitudinal media channels 6. The longitudinal media channel can be one or more layers, and the cross section of the longitudinal media channel can be circular, rectangular, honeycomb or other shapes.

Abstract

The invention discloses a high polymer material compounded plate type solar heat collector and a core veneer manufacturing method thereof. The heat collector comprises a transparent cover plate, a solar heat absorbing core veneer, an opaque baseplate and end sealing cross beams; the transparent cover plate, the solar heat absorbing core veneer and the opaque baseplate are arranged in sequence from top to bottom to form a main body structure of the plate type solar heat collector; and the end sealing cross beams are respectively arranged at two longitudinal ends of the main body structure. The core veneer manufacturing method comprises the following steps: firstly, mixing extrusion equipment is used for uniformly dispersing solar selective absorbing agent into a transparent plastic basal body to prepare a high polymer material for selectively absorbing sunlight energy; and then, a foaming plate with a continuous perforated structure is prepared by foaming through an intermittent method, a continuous extruding method or a thermal induction phase separation method, or a hollow plate with a longitudinal medium channel is manufactured through an extrusion or injection molding method. The plate type solar heat collector is light in mass, simple and reasonable in structure, convenient for installation and disassembly and capable of realizing integration with building.

Description

technical field [0001] The invention relates to the technical field of solar heat collectors, in particular to a polymer material-composited plate-type solar heat collector and a manufacturing method for a core plate thereof. Background technique [0002] In today's world, energy issues have become one of the main factors restricting the development of countries all over the world. Our country is a big energy consumption country, saving energy and reducing environmental pollution caused by energy consumption has attracted people's attention day by day. As a rich renewable energy source, solar energy has been widely developed and utilized in my country, such as converting solar energy into electrical energy by using the photoelectric effect, converting solar energy into thermal energy through heat collectors, converting solar energy into biomass energy through photosynthesis, etc. At the present stage in our country, solar collectors play a dominant role in the utilization of...
