The main material of the clear heat recovery rotor is aluminum alloy base material with a thickness of 0.06 to 0.07mm and a width of 100 to 280mm. Pure aluminum foil strips of different specifications are pressed into triangles through specially designed tooth surfaces and then inserted into flat plates of the same material aluminum foil for horizontal rolling. After layer upon layer superposition, a dense triangular air duct is formed until the required diameter for the design is achieved. The sensible heat recovery rotor has a highly efficient sensible heat recovery efficiency, recovering and releasing the heat/cold energy caused by the temperature difference changes in the air flow, thereby initially improving the temperature of the incoming air flow and simultaneously reducing energy consumption. However, due to the characteristics of the aluminum base material of the sensible heat recovery rotor, it cannot effectively recover water molecules in the air. When the temperature difference of the airflow reaches the condensation point, condensation water will precipitate. When the temperature on the windward side reaches the frosting point, frosting and ice crystal diffusion will occur.
