Instant temperature changing device includes reactant and activator liquid that generate an exothermic or endothermic chemical reaction when combined to heat or cool contents in the device. One temperature changing device includes an inner shell and an outer shell, an activator container, and a reaction chamber. Opening the activator container causes reactant to combine with activator liquid and undergo an exothermic or endothermic reaction to initiate heat transfer to or from the contents disposed in the inner shell.

Instant self-heating containers include a combinable reactant and activator used to generate an exothermic reaction for heating contents of the container. One instant self-heating container includes a target container, a pierceable activator container and a reaction chamber. Piercing the activator container causes activator to combine with the reactant and cause an exothermic reaction that heats the target container. The container may be used as depilatory wax dispenser. Another instant self-heating container includes an outer housing containing a contents pouch and a reactant, and capped by a lid having an activator chamber. Rupturing the activator chamber allows activator to combine with the reactant in an exothermic reaction to heat the contents pouch. Another instant self-heating container includes a flexible outer tube containing contents to be heated, a flexible reaction vessel, and a frangible activator vessel. Bending the outer tube causes the activator vessel to rupture and cause an exothermic reaction.

Ammonium carbamate-based methods and systems for management of thermal loads, particularly low-quality, high-flux thermal loads. The increase in temperature in heat sensitive devices is mitigated by the endothermic decomposition of ammonium carbamate into carbon dioxide and ammonia gases. This process has an energy density an order of magnitude greater than conventional thermal management materials and is particularly useful for temperatures between 20 C. and 100 C. Systems incorporating ammonium carbamate may be controlled by regulating the fluid flow, overhead pressure, temperature, or combinations thereof.

Self-heating apparatus and methodology for customizing a time-temperature profile thereof. The layered apparatus includes at least a layer of phase change material and a layer of air- or oxygen-activated material. When the air- or oxygen-activated material is activated, heat is released rapidly and is absorbed by the phase change material. The phase change material then releases the absorbed heat over a long period of time. Time-temperature profiles can be adjusted based on type, amount, and configuration of phase change and air-activated materials used. The apparatus and methodology allows rapid heat-up of times of a few minutes and lasts several hours at near constant tunable temperatures.
