Publication number: 20130119301Abstract: The chemical reactions modulation of temperature and dissipate heat through using phase change materials (PCM). Hydration of a mixture composed of encapsulated and/or non-encapsulated oxides such as calcium oxide and/or magnesium oxide and dehydrated and/or hydrated zeolite coupled with control of pH of mixture through compounds such as Citric acid, or combination exothermic mixes, such as Cao and Mg—Fe, provide sustained heat release and heat retention tailored by addition of PCMs. The modulation may include timed/controlled release from encapsulated reactants and may include particles with tailored size distribution and different burn characteristics. The phase change materials used include organics (paraffins, non paraffins and fatty acids) and inorganics (salt hydrates). The selection of PCM is based on compatibility with the reacting mix, added reacting aqueous medium, and the desired temperature the system is to be held constant or temperature range it is desired to be modulated.Type: ApplicationFiled: December 17, 2012Publication date: May 16, 2013Applicant: University of South FloridaInventor: University of South Florida

Publication number: 20130119302Abstract: An enhancing agent for increasing heat transfer efficiency is disclosed, which is an additive composed of a nano-scale powder and a micro-scale powder that is to be added into a heat-transfer fluid circulating in an heat exchange system or in a coolant circulating in a cooling system for enhancing the heat conductivity of the heat-transfer fluid or the coolant while helping the tank and the fluid passages used in those systems to maintain clean, and eventually enabling those systems to operate with improved heat dissipation effect. By adding the aforesaid enhancing agent into a cooling system of an internal-combustion engine, the heat shock inside the engine that is originated from the fuel burning in the engine can be reduced, resulting that not only the amount of green house gas emission is reduced, but also the chance of engine juddering that is generally originated from poor heat dissipation can be decreased.Type: ApplicationFiled: November 13, 2012Publication date: May 16, 2013Inventors: YEN-HAO HUANG, Hung-Wei Chen
