Embodiment Construction

[0035] Examples see figure 1 As shown, this aluminum-plastic solar heat collector includes a shell, a heat-absorbing pipe 5 in the shell, and a water delivery pipeline 3 communicated with the heat-absorbing pipe. The shell is surrounded by a hollow frame 2, a light-transmitting cover plate 1 located on the light-receiving surface and connected to the hollow frame, and a bottom plate 6 located on the backlight surface and connected to the hollow frame to form a flat box. The light-transmitting cover plate 1 is one to two layers of polycarbonate Ester film, the inner core of the hollow frame is equipped with a water delivery pipe 3 along the length, and the water delivery pipe 3 communicates with the heat-absorbing pipe 5 in the shell, the water inlet 11 and the water outlet 7 on the side of the hollow frame.

[0036] The heat-absorbing tube 5 is a row of parallel aluminum alloy tubes, its cross-sectional shape is elliptical, and its long axis is parallel to the light-transmitti...

Abstract

The invention relates to an aluminum-plastic solar heat collector. A shell is enclosed into a flat box body by a hollow frame, a transparent cover plate positioned at a light-receiving surface and connected with the hollow frame and a bottom plate positioned at the backlight surface and connected with the hollow frame, wherein the transparent cover plate is one to two layers of polycarbonate membrane; the inner core of the hollow frame is hidden with a water transmission pipeline along the length direction; the water transmission pipeline is communicated with a heat absorbing pipe in the shelland a water inlet and a water outlet at the side surface of the hollow frame; the heat absorbing pipes are a row of parallel aluminium alloy pipes, the cross section thereof are shaped as an ellipseand the long shaft thereof is parallel to the transparent cover plate; the heat absorbing pipe is externally wrapped with an aluminium foil coated with a selective heat absorbing coating; and the twoends of the heat absorbing pipe are respectively communicated with the water transmission pipeline of the hollow frame. The aluminum-plastic solar heat collector solves the technical problems that thetraditional solar heat collector has high cost and undesirable heat efficiency, is hard to be fused with the building structure and the building shape and has influence to large-scale application.

Description

technical field [0001] The invention relates to a solar heat collector. Background technique [0002] Solar collectors play an important role in the field of energy saving and emission reduction, and have become one of the main products in the new energy industry. The current solar collectors mainly include flat-plate solar collectors and all-glass vacuum tube solar collectors. [0003] Flat-plate solar collectors are generally composed of heat absorbers, light-transmitting cover plates, insulation layers and shells, and are shaped like flat square boxes. The heat absorbing plate is a part that absorbs solar radiation energy and transfers heat to the working medium of the collector. The materials mainly include copper, aluminum alloy, steel, galvanized sheet and stainless steel. The structure of non-ferrous metal heat-absorbing plates includes tube plate type, flat box type, and flat tube type. Do metal phase combination to reduce thermal resistance. The advantages of fl...
