Air-cooling device

A cooling device for providing cool air to a living being or an external environment, comprising:

• a hollow, device body comprising:
• a first body portion carrying a first cover and a second cover at a proximal end and a distal end, respectively, of the first body portion, the first body portion and the first and second covers fully enclosing a main chamber containing an amount of a cooling medium, the first body portion comprising a plurality of air passageways extending through the cooling medium such that the plurality of air passageways is surrounded in its entirety by the cooling medium and each air passageway of the plurality of air passageways is surrounded in its entirety by cooling medium, each air passageway comprising a respective proximal end and a respective distal end arranged at the proximal end and distal end of the first body portion, respectively, wherein the distal ends of the air passageways are in fluid communication with one another,
• a second body portion, disconnectably attachable to the distal end of the first body portion and comprising an internal space providing fluid communication between the distal ends of the plurality of air passageways,
• a fan body portion, disconnectably attachable to the proximal end of the first body portion, the fan body portion containing a fan,
• a water-absorbent material contained within the internal space of the second body portion, wherein the water-absorbent material is configured to collect condensate from outside air circulating through the plurality of air passageways;
• and
• at least one air inlet and at least one air outlet formed in the device body;
• wherein
• the cooling device is configured to selectively switch between:
• a first configuration and a second configuration, wherein, in both the first configuration and the second configuration, the first body portion and the first and second covers fully enclose the cooling medium such that said amount of cooling medium remains constant, wherein
• in the first configuration, the second body portion and the fan body portion are disconnected from the first body portion, and the first body portion and the first and second covers are jointly portable by a single hand of a user, and the cooling medium is coolable by placing the first body portion and the first and second covers, in a cooler or freezer, and
• in the second configuration, the second body portion and the fan body portion are attached to the first body portion, and the device body is portable by said single hand of said user, and fluid communication is provided from the at least one air inlet to the at least one air outlet via the plurality of air passageways to drive air from outside the cooling device through the at least one air inlet, cool said air by heat exchange with the cooling medium as the air passes through the plurality of air passageways, and deliver said cooled air through the at least one air outlet responsively to operation of the fan.
