Abstract
A heater device applied in a desiccant rotor dehumidifier for supplying regeneration hot air to the desiccant rotor comprises a metal case having an air inlet and an air outlet; heating elements supported by insulative material and mounted adjacent to the desiccant rotor; and an insulative plate installed in parallel to the heating elements and parting the heating elements with the air inlet. The insulative plate is formed with a plurality of via holes suitably distributed for the intake air coming from the air inlet passing through, being heated by the heating elements and evenly passing the desiccant rotor through the air outlet. The insulative plate also splits and bypasses a part of the intake air to cool down the desiccant rotor that has been heated and regenerated.
