Description
Technical field:
The present invention relates to a kind of enhancement of heat transfer phase-change accumulation energy fluid and preparation method thereof, belong to functional materials fabricating technology field.
Technical background:
Phase-changing energy storage material is with a wide range of applications in fields such as weaving, building, sun power utilizations.In prior art, phase-changing energy storage material mainly forms the form use of microcapsule with the polymer overmold phase change material, can avoid like this problems such as contingent fusion, loss when phase change material becomes liquid phase.But, relatively poor as the common heat conductivility of the polymkeric substance of coating layer, when the size of phase transformation capsule is larger, perhaps conduct heat the time more in short-term, quite a few phase change material has little time to undergo phase transition, thereby energy storage efficiency is reduced greatly.For polymkeric substance, it is high a lot of that the thermal conductivity of metallic copper is wanted, if a certain proportion of metallic copper particle is arranged in phase-changing energy storage material very much, its heat conductivility will significantly improve.The present invention comes the heat transfer property of fortification system by adding metallic copper particle, thereby improves the energy storage efficiency of phase-changing energy storage material.
The method for preparing at present phase-change microcapsule is mainly microemulsion method, namely when phase change material is in liquid phase, is distributed in water together with polymer monomer, forms emulsion under Action of Surfactant, and then initiated polymerization forms phase-change microcapsule.This method complex process, bad control, output is not high.The more important thing is, will add equably metallic copper particle very difficult in this method.In fact, polymkeric substance kind involved in the present invention all has ripe large-scale production process, and is more much bigger than the output of emulsion polymerization technique.These polymkeric substance and all may be dissolved in suitable polar organic solvent as stearic acid and the phase change paraffin of phase change material, thus slurry formed.Can add easily metallic copper particle in the process that forms slurry.In the time being distributed to material in water, due to the polar organic solvent that adopts and water miscible, and polymkeric substance used and phase change material are all water insoluble, so polar organic solvent is seized by water, separate out the solids mixing composition granule that contains polymkeric substance, phase change material, metallic copper particle.
The phase-change accumulation energy fluid refers to contain a class soft material of phase change material in liquid phase medium.Liquid phase medium wherein is mainly common heat-transfer fluid such as water, ethylene glycol, propylene glycol etc.Owing to containing a certain amount of phase-changing energy storage material, the thermal capacity of phase-change accumulation energy fluid improves a lot with respect to simple heat-transfer medium.During the phase-change accumulation energy fluid operating, heat is passed to fluid medium from thermal source, and its temperature is raise, and stores sensible heat.Then heat is passed to phase-changing energy storage material (usually being comprised of polymer covering layer and phase change material) from fluid medium, makes its intensification, stores sensible heat.When temperature rose to the transformation temperature of phase change material, phase change material underwent phase transition, and stored latent heat.To finish the needed time fully relevant with the thermal conductivity of phase-changing energy storage material from beginning to undergo phase transition phase transition process.The prepared phase-changing energy storage material of the present invention is owing to having added metallic copper particle, thermal conductivity enlarges markedly, the needed time shorten of phase transition process, the time of phase-change accumulation energy fluid and Source also can correspondingly shorten, in unit time, the flow of phase-change accumulation energy fluid can correspondingly increase, thereby stores more heat.
Summary of the invention:
The present invention prepares the method that becomes the energy storage fluid and comprises the following steps:
Polymkeric substance and phase change material are dissolved in form mixing solutions in polar organic solvent, then metallic copper particle is added in above-mentioned mixing solutions, stir and obtain slurry, then above-mentioned slurry is distributed in water, utilize the difference of polymkeric substance and phase change material solubleness in organic solvent and water, separate out solid particulate, more above-mentioned solid particulate is separated from liquid phase, be re-dispersed into the phase-change accumulation energy fluid that is strengthened in the heat-transfer fluid medium and conduct heat.
The method suitability extensively, mild condition, technique be simple, is easy to suitability for industrialized production.Gained enhancement of heat transfer phase-change accumulation energy fluid can as multiple uses such as engine coolant and solar energy collector working fluids, have good popularizing application prospect.
