A method for quantitatively characterizing response speed of phase change energy storage composite material in multiple dimensions

Abstract

The present application relates to a kind of multi-dimensional quantitative characterization phase change energy storage composite response speed method.Different phase change energy storage composite thermal conductivity, internal pore size and the difference of different heat conduction path are utilized to carry out thermal response test.Phase change energy storage composite is surface treated, silicon grease is daubed, thermocouple is pasted, temperature and time of different time periods are recorded by fixing the temperature rising rate or power of temperature rising stage, data is extracted, graph is made, and the response temperature and response time of different phase change energy storage composites are obtained by analyzing image.Therefore, the new response speed test method has great application prospect for phase change energy storage material.
