Specifically, the cooling medium is located in the cooling channel 212, when the hot and humid air entering the dehumidifying device body 1 contacts the cooling part 21, the heat of the hot and humid air is transferred to the outer wall of the cooling part 21, the cooling medium in the cooling channel 212 absorbs the heat of the outer wall of the cooling part 21, and then the heat of the hot and humid air is finally transferred to the cooling medium, so as to cool the hot and humid air in the cavity 11. In addition, the partition 211 and the inner contour of the cavity jointly form a cooling channel 212, so that the space of the cooling channel 212 is increased, the retention time of a cooling medium in the cavity is prolonged, and the cooling performance of the cooling medium in the cooling channel 212 is fully utilized; through baffle 211 and the cooling channel 212 that holds the interior profile of chamber and form the curved shape jointly, replace the traditional scheme that adopts curved pipe structure as cooling channel, reduced the space that the interval between two adjacent pipeline sections that traditional pipeline structure is crooked and cause occupy, improved the space size of the cooling channel 212 that same chamber space corresponds promptly, improve the coolant's that cooling portion 21 held the volume for the heat transfer. Two adjacent partition boards 211 are respectively connected to two inner walls of the cavity in a staggered manner.
