Abstract
The disclosure generally relates to compositions, methods, and systems for heat transfer and methods of preparing heat transfer mediums. In various embodiments are described heat transfer mediums comprising a plurality of microparticles suspended in a bulk material with each microparticle containing a phase change material. In other embodiments are described fluids comprising of a slurry of microparticles containing phase change fluid in a carrier liquid for a fast charger system.
Claims14
A heat transfer system comprising:
- a plurality of microparticles within a bulk material, where each microparticle has a shell enclosing a cavity having a pressure (PInternal) independent of pressure outside the shell and including a phase change material having a boiling point temperature (TBP) at PInternal;
- and
- first (HE1) and second (HE2) heat exchangers thermally connected to the plurality of microparticles;
- wherein HE1 is configured to heat the plurality of microparticles to at least TBP at PInternal to cause the microparticles to rise within the bulk material;
- wherein HE2 is configured to cool the plurality of microparticles to below TBP at PInternal to cause the microparticles to fall within the bulk material.
