If the tube panel adopts the structural style of the pipe clamp of the traditional riser, the heat displacement of each heat absorbing pipe cannot be accurately limited, so that the heat displacement sliding of the heat absorbing pipe is easily blocked to cause large local stress at the support and damage the pipeline, the traditional support is extremely difficult to disassemble and assemble, and the workload of tube panel installation and maintenance is large. In addition, a heat bridge is formed between the heat absorption pipe and the internal steel structure in the traditional support mode, heat loss is increased, heat efficiency of the heat absorber is reduced, and potential safety hazards to the internal structure are caused when the heat absorber runs for a long time.
