摘要
相变流体(PCS)是一种新颖的储传热介质,其表观比热和传热能力比水大,在换热强化和能量输运领域有广泛应用,但传统的相变流体在实际应用中有很大的缺陷。使用工业级相变石蜡制备了一种新型相变储能微乳液,并测定了该材料的相变微粒的粒径、粘度、相变潜热及稳定性等性质。测试结果表明,制备的相变微乳液拥有较高的储能能力和稳定性,在热交换等领域具有广阔的应用前景。
Phase change slurry(PCS)is a fluid for heat storage and transfer and it is advantageous in the field of the convective heat transfer enhancement.But traditional PCSs always have problems in application.In this paper,aphase change microemulsion is prepared to solve problems.Physical properties of phase change microemulsion were test and results show it has high latent heat and stability.It will be potential for application.
