Aerogel composite products have great advantages in heat pipe networks.Aerogel-fiber composites can change the heat transfer capacity of raw materials and enhance heat transfer.Through an analysis on theoretical calculations and measured values of heat insulation of main heat pipes in a heat exchange station,the energy-saving effect of aerogel composite insulation materials in the heat exchange station was demonstrated.In addition,a mathematical model of aerogel heat transfer was established,and its parameters were calculated with finite element analysis software,thus providing an effective theoretical basis for better pipe insulation calculation.
