MICROCAPSULE DISPERSION FOR THERMAL STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To obtain a microcapsule dispersion, having a relatively high heat transfer coefficient between the dispersion and a member constituting a heat exchange flow passage for flowing the dispersion therethrough and useful as a thermal storage medium. SOLUTION: This microcapsule dispersion for a thermal storage medium is obtained by selecting the volume-average particle diameter of a microcapsule A for a small-particle diameter thermal storage medium as 1-5μm and stably dispersing a particulate material B for stirring a temperature boundary layer having the volume-average particle diameter selected as 10-100μm in addition to the microcapsule A when composing the microcapsule dispersion for the thermal storage medium prepared by stably dispersing the microcapsule A for the small-particle diameter thermal storage medium comprising an organic compound, causing a phase change as the thermal storage medium and contained in the microcapsule A in a fluidic medium for conveying.
