Patent ID: 8784529

Claim:
A dehumidifier comprising: at least one moisture removing component; a heat exchange block that directs an airflow through the moisture removing component, the heat exchange block including a plurality of spaced-apart elements having multiple airflow channels; a plurality of spacers positioned between neighboring elements and extending in a first direction, to space the corresponding elements apart from each other by a gap; a first airflow path extending in the first direction through the gaps between corresponding elements; a second airflow path extending through the airflow channels in a second direction, the heat exchange block having a first major surface generally parallel to the first direction and a second major surface generally parallel to the second direction; wherein the first and second major surfaces include a notch having a first notch surface generally parallel to the first major surface and a second notch surface generally parallel to the second major surface; and wherein the heat exchange block further includes an airflow blocker sealingly positioned in the notch to at least partially block air from passing between the first and second airflow paths in the heat exchange block, wherein the airflow blocker is in contact with the first and second notch surfaces.
