An apparatus for heating a product includes a storage compartment for a product to be heated and a heater module physically and thermally coupled to the storage compartment. The heater module has a housing that defines a reaction chamber. A rigid barrier is inside the reaction chamber and defines first and second portions thereof. A first reactant is inside the reaction chamber, and a flexible bag (with a second reactant) is in the first portion of the first chemical reactant. The first and second reactants react exothermically upon contact. A piercing element can pierce the flexible bag. After piercing, the a fluid path and one or more fluid channels carry the second reactant to a section of the first portion of the reaction chamber away from where the flexible bag is located.

The present invention pertains to cooling, heating, and refrigeration cycles using, for example, phase transitions to pump heat. Embodiments of the present invention may comprise systems, methods, or processes for liquid-liquid phase transition refrigeration cycles pumping heat across temperature differences greater than the adiabatic temperature change of a liquid-liquid phase transition within said liquid-liquid phase transition refrigeration cycle. Embodiments of the present invention also may comprise powering said liquid-liquid phase transition refrigeration cycle using electricity, heat, cold, the mixing of a saltwater and freshwater, the mixing of high osmotic pressure liquid and low osmotic pressure liquid, or a combination thereof.

Provided herein is a composite material that includes at least one thermoresponsive polymer and at least one organic foam material. Further provided herein is a method for producing the composite material and also to the use of the composite material for cooling and for regulating temperature.

There is described an apparatus for heating or cooling a material to be heated or to be cooled. The apparatus includes: a first compartment for containing the material to be heated or to be cooled; and a second compartment containing a phase change material, wherein the phase change material is either for generating heat to heat the first compartment or absorbing heat to cool the first compartment when undergoing a phase change. There are further described various different activating arrangements for activating a change of phase of the phase change material.

A novel self-cooling food product container apparatus (10) and a process for manufacturing the same is disclosed. A self-cooling food product container (20) combined with a substantive vapor transport system producing a humidification cooling process for cooling food and beverage products P. Methods of assembling and operating the apparatus (10) are also provided.

A system includes a guided munition having a housing. A first reservoir is defined within the housing holding a first chemical reactant. A second reservoir is defined within the housing, wherein the second reservoir holds a second chemical reactant configured to undergo an endothermic reaction with the first chemical reactant. A frangible barrier separates between the first and second reservoirs. The frangible barrier is configured to break under forces acting on the guided munition as the guided munition is fired from a weapon. An electronic device can be housed within the housing in thermal contact with at least one of the first reservoir and/or second reservoir for cooling the electronic device with an endothermic reaction upon mixing of the first and second chemical reactants.
