Active dehumidifying container having a dehumidification box module

An active dehumidifying container, comprising a dehumidification box module installed on a side wall of the container to allow communication between internal air and external air of the container while regulating internal humidity of the container,

• wherein the dehumidification box module comprises:
• a coupling member (220) installed to penetrate the side wall of the container, having one end disposed inside the container and the other end disposed outside the container, and having an air flow path therein;
• a valve member (240) having a 2-1 end (242) coupled to the one end of the coupling member, and a 2-2 end (244) and a 2-3 end (246) each communicating with the 2-1 end;
• a vertical cylindrical member (260) coupled to the 2-2 end (244) of the valve member to guide air flow downward;
• a vertical plate (270) coupled with the vertical cylindrical member such that air exiting from the vertical cylindrical member flows therein;
• and
• a dehumidification space (280) disposed on an internal air flow path of the vertical plate and provided with a desiccant therein to remove moisture from the flowing air,
• wherein the external air of the container is introduced into the container interior after moisture is removed while passing through the coupling member, the valve member, the vertical cylindrical member, the vertical plate, and the dehumidification space, and
• wherein the internal air of the container is discharged to the outside of the container through the valve member and the coupling member.
