Embodiment Construction

[0027] like figure 1 , figure 2 As shown, the polypropylene integral foam flat solar collector of the present invention is mainly composed of transparent cover plate 1, heat-absorbing plate core 2, polypropylene integral foam outer frame 3 and polypropylene foam decorative bead 4 and other components. Among them, the transparent cover plate 1 is made of high light-transmitting tempered glass; the heat-absorbing plate core 2 is composed of a copper pipe frame 21 and an aluminum plate 22 coated with a heat-absorbing coating through laser or ultrasonic welding; The foam is made into a "concave" groove shape, and a metal skeleton 31 is put into the inside of the overall polypropylene foam frame 3 before foaming to increase the fastness of the polypropylene overall foam frame 3.

[0028] The connection relationship of the parts of the polypropylene integral foam flat panel solar collector of the present invention is as follows: the heat-absorbing plate core 2 is installed inside ...

Abstract

The invention discloses a polypropylene overall foaming flat-plate solar collector which is mainly composed of a transparent cover board, an absorber plate core, a polypropylene overall foaming external frame, a polypropylene foaming decorative pressing strip and other components, wherein, the absorber plate core is formed by performing laser welding or ultrasonic welding on a copper pipe support and an aluminum plate coated with a heat absorbing coating; and the polypropylene overall foaming external frame is pre-made into a 'groove' shape through foaming, and a metal framework is placed in the polypropylene overall foaming external frame before the foaming so as to strengthen the firmness of the polypropylene overall foaming external frame. In the polypropylene overall foaming insulation flat-plate solar collector, good properties of polypropylene is fully utilized and the polypropylene overall foaming external frame made by an overall foaming technology is employed, thus greatly improving the overall strength, the beautiful degree and the overall thermal insulation property of the whole solar collector, greatly reducing the overall weight, and greatly lowering the production cost; and in addition, the polypropylene overall foaming flat-plate solar collector also has the functions of corrosion prevention, compression resistance, environmental protection and the like.

Description

technical field [0001] The invention discloses a polypropylene integrally foamed flat solar heat collector, which belongs to the field of flat solar heat collectors. Background technique [0002] Foam plastic has the advantages of light weight, heat insulation, cushioning, insulation, anti-corrosion, and low price, so it has been widely used in all walks of life. At present, the main varieties of foam plastic are polyurethane (PU) soft and rigid foam plastic, polyurethane There are three categories of styrene (PS) foam and polyethylene (PE) foam. However, there are isocyanate residues harmful to the human body during the foaming process of polyurethane foam, and the foamed material cannot be recycled. However, chlorofluorocarbons or butane are usually used in the polystyrene (PS) foaming process, which has adverse effects on the environment, and the product is difficult to degrade and easily forms "white pollution". Polyethylene foam is less rigid and has a maximum service...
