Reason why the room is not hot after adding a heating hood
Radiator is the radiator heating the surrounding air, and then the hot air rises and flows away. The cold air continues to flow and is heated again. This endless circulation creates air convection and transfers the heat of the hot water in the radiator to the room. If the radiator is closed by the heating hood, air convection cannot be formed, and it is difficult for the radiator to release heat by convection. In addition, because the surface temperature of the radiator is higher than the temperature of the indoor object, the hot surface of the radiator continuously emits heat radiation to the surrounding objects and the wall to heat the room. The heat radiation is performed in a straight line. If the heat sink is covered, the heat of the heat sink can only be radiated to the inner surface of the cover, and then the secondary radiation is conducted through the outer surface of the heating cover, and the radiant heat is greatly reduced. In this way, the room is not hot, because the room is not getting heat before the heating hood.
