Abstract

A cooling unit that can be used with or without a garment, such as a ballistic vest, that covers a user's torso when worn by the user. The cooling unit includes a fan for blowing ambient air; a manifold for distributing to the torso the air that is blown by the fan; and a hose for connecting the fan to the manifold. The manifold may be formed of three overlying panels that are secured together, including an outer panel, a central panel, and an inner panel that is closest to the user's torso when the cooling unit is being worn. No modification of the vest is necessary to accommodate the cooling unit.

First claim

The invention claimed is:

1. A cooling unit that can be worn on a user's torso by itself or in association with a garment such as a ballistic vest, the cooling unit comprising:
a fan for blowing ambient air; and
a manifold connected with the fan for distributing the air to the torso;
the manifold formed of at least three panels that are secured together, the manifold including an outer panel, a central panel, and an inner panel that is closest to the user's torso when the cooling unit is being worn;
the outer panel and the central panel defining between them an air inlet chamber that is in fluid communication with the fan for receiving air blown by the fan;
the central panel and the inner panel defining between them an air outlet chamber that is in fluid communication with the air inlet chamber and that directs air from the air inlet chamber to a central opening in the inner panel thereby to contact a spinal area of the user's torso;
wherein the air outlet chamber comprises a collector channel on the central panel and a diffuser channel on the inner panel whose volumes join to form the air outlet chamber.

2. The cooling unit as set forth in claim 1 , wherein the collector channel and the diffuser channel are each U-shaped with legs that extend on either side of the central opening in the inner panel.

3. The cooling unit as set forth in claim 2 , wherein the collector channel has a plurality of fingers that have air inlet openings, the fingers directing air from the air inlet openings into the legs of the collector channel, the collector channel having air outlet openings adjacent the central opening of the inner panel for directing the blown air through the central opening of the inner panel.

4. The cooling unit as set forth in claim 1 , wherein the diffuser channel on the inner panel includes a plurality of fingers extending from the legs of the diffuser channel, the fingers on the diffuser channel having air outlet openings spaced outward from the central opening of the inner panel for directing the blown air through the air outlet openings on the back of the user's torso laterally outward of the central opening of the inner panel.
