This utility model discloses a multi-channel duct dehumidifier, which includes a support frame, a cover plate, an exchange chamber, an inlet pipe, an outlet pipe, and a drain pipe. This multi-channel duct dehumidifier uses metal pipes directly welded to the exchange chamber. Due to the good thermal conductivity of the metal pipes, they can also maintain a low temperature like the exchange chamber, thereby increasing the cooling path of the gas flow and improving the dehumidification effect.
