Abstract
The utility model discloses an antifreezing flat-plate solar collector. The solar collector consists of a bottom board (1), an insulating layer (2), an electric heating film (3), a flat-plate collector (4), a piece of flat-plate glass (5) and a frame (6), the bottom board (1) and the flat-plate glass (5) are arranged on the frame (6) by a screw (7) and form a closed installation cavity, the periphery of the installation cavity is closed by the insulating layer (2) made of polyurethane or rock wool, the flat-plate collector (4) and the electric heating film (3) are arranged in the installation cavity, the electric heating film (3) is laid at the back side of the flat-plate collector (4), and the flat-plate glass (5) is covered by the sunny slope of the flat-plate collector (4). According to the utility model, a solar water heater can be normally used in winter, the heat transfer efficiency is high, the installation and maintenance are convenient, and the reliability is good.
Description
Technical field
The utility model relates to solar thermal collector, is specifically related to a kind of antifreeze flat-plate solar collector.
Background technology
As everyone knows; The critical piece flat-plate solar collector of flat plate solar water heater adopts compound heat collecting sheet of copper aluminium and copper pipe fitting to form more; Antifreeze function is poor, winter often occurs heat collecting sheet or the pipe fitting bursting by freezing situation of leaking, causes the solar water heater cisco unity malfunction.
At present, adopt anti-icing fluid as the medium transferring heat energy on the market more.Anti-icing fluid freezing point low energy plays the effect that prevents that heat collector is freezing, but anti-icing fluid has also brought some new problems as medium: heat transfer efficiency descends, and leaks the back environment and water body are polluted.
Summary of the invention
The purpose of the utility model is: a kind of antifreeze flat-plate solar collector is provided; Adopt the temperature automatically controlled Electric radiant Heating Film of low power consuming to be incubated to flat plate collector; Not reducing heat transfer efficiency, not producing under the condition of pollution, effectively solve the problem of flat plate collector bursting by freezing.
The technical solution of the utility model is: this solar thermal collector comprises base plate, heat-insulation layer, Electric radiant Heating Film, flat plate collector, plate glass and framework; On framework, base plate and plate glass are installed through screw; Base plate and plate glass constitute the sealing installation cavity, and it is closely knit to make heat-insulation layer with polyurethane or rock wool around the installation cavity, and flat plate collector and Electric radiant Heating Film are installed in the installation cavity; Electric radiant Heating Film is laid at the back side of flat plate collector, and the sunny slope of flat plate collector covers plate glass.
The Electric radiant Heating Film of the utility model is the translucent polyester film that can generate heat after a kind of energising; There are conductive semiconductor nano carbon, the hot pressing of metal current-carrying bar between insulation polyester film, to form; With the outside transferring heat energy of the form of far infrared, guarantee that flat plate solar water heater can both normally use in the winter time, heat transfer efficiency is high; Convenient for installation and maintenance, good reliability.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 base plate, 2 heat-insulation layers, 3 Electric radiant Heating Film, 4 flat plate collectors, 5 plate glass, 6 frameworks, 7 screws.
The specific embodiment
As shown in Figure 1; This solar thermal collector comprises base plate 1, heat-insulation layer 2, Electric radiant Heating Film 3, flat plate collector 4, plate glass 5 and framework 6, on framework 6, through screw 7 base plate 1 and plate glass 5 is installed, and base plate 1 constitutes the sealing installation cavity with plate glass 5; It is closely knit to make heat-insulation layer 2 with polyurethane or rock wool around the installation cavity; Flat plate collector 4 and Electric radiant Heating Film 3 are installed in the installation cavity, and Electric radiant Heating Film 3 is laid at the back side of flat plate collector 4, and the sunny slope of flat plate collector 4 covers plate glass 5.
