Embodiment approach
[0019] Such as Figure 1 to Figure 3 An embodiment of the manufacturing method of the heat absorbing body of the all-aluminum flat solar collector of the present invention is shown, and the steps include:
[0020] A. Strips extruded by an aluminum alloy extruder. The strips are composed of heat absorbing plate 1 and runner 2, and heat absorbing plate 1 and runner 2 are integrally formed;
[0021] B. Plating the front surface of the strip with a heat-absorbing coating;
[0022] C. Cut off the two ends of the heat-absorbing plate 1 by 1-10cm to expose the runner 2;
[0023] D. Deoxidize the surface of the exposed end ports of the runner 2;
[0024] E. Deoxidize the interface of header 3;
[0025] F. Use TIG welding to weld the interfaces between the two ends of the runner 2 and the header 3.
[0026] The heat-absorbing plate and the runner are integrated, so that the surface of the heat-absorbing plate is flat, which solves the marks and wrinkles between the heat-absorbing plate and the ru...

The invention discloses a manufacture method of a full-aluminum flat-plate solar heat collector heat-absorbing body. The manufacture method comprises the following steps of: extruding formed stripes by an aluminum alloy extruder, wherein each stripe comprises a heat absorbing plate and a runner, and the heat absorbing plates and the runners are integrally formed; plating a heat absorbing coating on the front surface of each stripe; respectively segmenting two ends of each heat absorbing plate by 1-10cm to expose the runner; removing oxide films on surfaces of ports in two ends of the exposed runner; removing oxide films of ports of headers; and welding ports in two ends of the runners with connectors of the headers by adopting TIG (Tungsten Inert Gas) arc welding. The full-aluminum flat-plate solar heat collector heat-absorbing body has the advantages of simple structure, low production cost and high production efficiency.
Description
technical field [0001] The invention relates to the technical field of a flat-plate solar water heater, in particular to a method for manufacturing a heat absorbing body of an all-aluminum flat-plate solar heat collector. Background technique [0002] With the improvement of human energy-saving awareness, solar heating is used more and more, and flat-panel solar collectors have always been the most widely used collectors for solar heating. At present, the heat-absorbing bodies of flat-plate heat collectors are mostly welded heat-absorbing aluminum plates or copper plates on copper tubes. Due to the high price of copper, the cost of heat collectors is relatively high. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, and to provide a method for manufacturing the absorber of an all-aluminum flat solar collector with simple structure, low production cost and high production efficiency. [0004] The purpose of the ...
