## Abstract

A modular, cooling device for providing cool air to a body and/or an external environment comprises a first body portion combining a cooling medium and air passageways therethrough. The first body portion may be detached from second and third body portions and placed in a freezer to refreeze the cooling media, and reattached for further use. The second body portion may include a material that absorbs condensate that forms within the air passageways. The third body portion may include a fan for driving air into the cooling device, through the air passageways and out of the cooling device. When passing through the air passageways, a heat transfer is produced between the passing air and the cooling medium, cooling the passing air. The fan speed may be varied to adjust air flow.
