Forced convection is the circulation of fluid driven by external forces. Natural convection is due to the change of density gradient at different temperatures and gravity. Flow from top to bottom, high-temperature density fluid flows from bottom to top, the heat loss generated in the process of convective heat transfer is convective heat loss, the usual convective heat loss is latent heat, sensible heat enclosure heat in the drying process The sum of losses is more than twice, and the existing devices used for the treatment of convective heat loss phenomenon only recover part of the heat emitted by convection, which has low efficiency, large energy consumption and environmental damage.
