Embodiment Construction
[0016] See attached figure 1 . A method for manufacturing a full-channel double-sided heat-collecting rare-earth aluminum alloy solar heat collecting plate, characterized in that: using the aluminum alloy door and window material production process, the rare-earth aluminum alloy is extruded through a full-channel mold into a full-channel rare earth aluminum alloy panel For the hot plate green body, in addition to chemically treating the front surface of the green body to become a solar heat collecting layer, the back surface of the green body is also chemically treated to become a solar heat collecting layer, or in addition to spraying solar energy absorbing paint on the front surface of the green body In addition, the solar energy absorbing paint is sprayed on the back surface of the green body, and the base layer is made of a full-channel rare earth aluminum alloy structure layer 1-1, and the front surface layer and the back surface layer are full-flow channels of the solar ...
