Manufacturing method and application of whole-flow-passage double-face-heat-collection rare earth aluminum alloy solar panel

Abstract

The invention provides a manufacturing method and application of a whole-flow-passage double-face-heat-collection rare earth aluminum alloy solar panel. The manufacturing method is characterized in that rare earth aluminum alloy is squeezed to form a whole-flow-passage rare earth aluminum alloy solar panel blank, the surface of the front face of the blank is subjected to chemical processing to form a solar heat collection layer, the surface of the back face of the blank is also subjected to chemical processing to form a solar heat collection layer, or the surface of the front face of the blank is coated with solar energy absorption coating, the surface of the back face of the blank is also coated with solar energy absorption coating, and therefore the whole-flow-passage double-face-heat-collection rare earth aluminum alloy solar panel 1 with the base layer being the whole-flow-passage rare earth aluminum alloy structure layer 1-1 and the front surface layer and the back surface layer being the solar heat collection layers 1-2 is obtained. The application of the whole-flow-passage double-face-heat-collection rare earth aluminum alloy solar panel is a split type whole-flow-passage double-face-heat-collection rare earth aluminum alloy solar water heater. Compared with the prior art, the heat collection and transfer area is substantially increased, heat conduction is quicker and more direct, solar heat collection and transfer efficiency is substantially improved.

Description

technical field [0001] The invention relates to the technical field of solar heat collecting plates, in particular to a manufacturing method and application of a full-channel double-sided heat collecting rare earth aluminum alloy solar heat collecting plate. Background technique [0002] Rare earth alloy micro-channel heat collector is a new type of solar heat collector developed by Shandong Zouping Weirui Refrigeration Co., Ltd. Because of the addition of rare earth elements in aluminum alloy, the rare earth alloy micro-channel heat collector has excellent anti-corrosion performance The thermal energy is more than ten times higher than that of other aluminum products, and the flow channel area is one-third of the whole plate. One-third of the plate has not been fully utilized, and it can only collect heat on one side, which affects the efficiency of heat collection and heat transfer. When using it, it needs to use a heat exchange medium. The installation is more complicated...
