[0069] The sealing mode of the core assembly 10 of the present application, on the one hand, omits sealing components such as sealing strips, so that the core body 11 is more convenient to arrange with each partition portion 22; on the other hand, since at least part of the positioning assembly 12 is movably arranged, when the core body 11 is arranged, at least part of the positioning assembly 12 can be moved to form a avoiding state, thereby facilitating the arrangement of the core body 11; thirdly, after the core body 11 is arranged to a predetermined position, at least part of the positioning assembly 12 is moved to extend out of the core body 11 and abut at least one partition portion 22 to position the core body 11, so as to prevent the position of the core body 11 from deviating to affect the sealing effect of each sealing cavity 210. It can be seen that the core assembly 10 is convenient to arrange and has good positioning effect, and can well ensure the sealing effect of each sealing cavity 210. When the core assembly 10 is applied to a dehumidification device, two sealing cavities 210 of the plurality of sealing cavities 210 form a fresh air chamber and a return air chamber, respectively, which can well ensure the sealing effect of the fresh air chamber and the return air chamber, thereby solving the problem that the sealing mode of the heat exchange core of the fresh air dehumidifier in the prior art cannot ensure the sealing effect of the fresh air chamber and the return air chamber.

[0070] The dehumidification device 20 of the present application comprises the above-mentioned core assembly 10, so the dehumidification device 20 at least has the same technical effects as the core assembly 10.
