Abstract:
A microenvironment system for use with a heat transfer fluid includes a microenvironment structure and a fluid handling apparatus. The microenvironment structure defines a flow passage to receive a flow of the heat transfer fluid therethrough. The fluid handling apparatus is adapted to provide a flow of the heat transfer fluid through the flow passage. The fluid handling apparatus includes a gas driven pump and a supply of a phase change material (PCM). The gas driven pump is operable to force the flow of the heat transfer fluid through the flow passage. The supply of the PCM is convertible from a solid and/or liquid phase to a gas phase to provide a pressurized drive gas. The fluid handling apparatus is configured to drive the gas driven pump using the pressurized drive gas from the supply of the PCM.

Abstract:
A temperature control system adapted for use with an article of clothing and designed to cool the wearer of the article of clothing. The temperature control system comprises a canister containing a cooling agent in its gaseous or vaporous state, a regulator for adjusting the flow of cooling agent from the canister and at least one supply line for delivering the cooling agent to an optimal release point. The canister can be an integral part of the article of clothing adapted to be recharged with the cooling agent or can be removable from the article of clothing, adapted to be refilled and replaced. The at least one supply line can be a plurality of supply lines delivering cooling agent to several optimal release points located within the article of clothing. The regulator enables the user to adjust the amount of cooling agent in order to obtain an optimal level of comfort. The temperature control system can be incorporated into any type of clothing article or apparel, including shirts, pants, blouses, footwear (shoes and boots), headgear (caps, hats, helmets), gloves and belts.

Abstract:
A thermal lining includes a first layer, a second layer overlappedly attached to the first layer in an edge to edge manner to form a construction pocket between the first and second layers wherein the construction pocket is shaped and sized for receiving in a storage compartment of a wear, and a cooling agent, having water absorbing ability, disposed in the construction pocket to form a heat insulation layer between the first and second layers. Therefore, the wearer is able to soak the thermal lining into the water, in such a manner that the water is permeated through the first layer into the construction pocket and absorbed by the cooling agent therein. The cooling agent with the water absorbed therein is adapted for receiving heat energy and gradually releasing the heat energy by evaporating the water, so as to provide the cooling effect for the wearer.

The present invention concerns an Individual cooling system comprising: (a) a garment V; (b) a container containing a block of material liberating an amount of cooling energy by phase change; (c) a pump P. The invention characterized in that it comprises means enabling the continuous operation of the assembly without solidification of the heating medium, even if the solidification temperature of the heating medium is higher than the temperature of the block of material releasing the cooling energy by phase change.
Abstract:
Provided herein are articles of headwear that comprise a pouch portion which may be charged with ice. Ice so charged is caused to melt under the effects of ambient temperature and is caused to drip from the pouch portion onto the neck of a person wearing such article. According to a preferred form of the invention, the head of a wearer is not contacted by ice or water during use of such article.
Abstract:

A second tube extends into the housing whereby the second tube is in fluid connection with the discharge portal. The second tube extends perpendicular to the second side of the housing. The second tube arcs away from the lid. A fan draws air into intake portal. A power source is operationally coupled to the fan.
Abstract:
A device for providing cooling relief for the body, especially during physical recreational/leisure activities, is disclosed which makes use of a water-permeable tubular material envelope containing a particulate resinous gel-forming material. The particulate resinous material, when hydrated by emersion in water, forms a soft pliable gel-like substance. The cooling effect of this device is provided by the evaporation of water from the surface of the material envelope. The filamentous components of the material envelope, by capillary action, wick water from the interstitial spaces in the water hydrated gel material, carrying the water to the material/air/skin interface. The water evaporating from that interface results in the evaporative cooling effect. In an alternative embodiment, the device also includes means for producing either an endothermic or exothermic reaction within or in close proximity to the material envelope for the purpose of enhancing the cooling process (endothermic), particularly in higher humidity conditions, or, alternatively, to provide a source of heat (exothermic) in certain situations, for example, for application to sore muscles. The device is simple and convenient to use in virtually any location, indoors or out, and can be utilized in the cooling configuration during a variety of recreational and leisure activities to mitigate the uncomfortable effects of heat.
