PROBLEM TO BE SOLVED: To improve dehumidification efficiency by improving the heat exchange efficiency of a heat exchanger.SOLUTION: A dehumidifier 1 comprises: a dehumidification rotor 200 which adsorbs moisture out of treatment air passing through a treatment air path 2 and discharges the moisture adsorbed into regeneration air passing through a regeneration air path 3; a heating means 250 disposed upstream of the dehumidification rotor 200 on the regeneration air path 3; and a heat exchanger 350 that makes the treatment air passing outside exchange heat with the regeneration air passing inside. The heat exchanger 350 has a first header part 370 into which the regeneration air flows, a second header part 380 that exhausts the regeneration air, and a plurality of channels 361 that connect them via fluid. The first header part 370 has an inflow port 371 disposed so as to face the heating means 250, an outflow port 372 opened in a direction crossing a direction in which the regeneration air flows in from the inflow port 371, and a guide wall 375 that guides the regeneration air into the outflow port 372.SELECTED DRAWING: Figure 7 |
