Computer Assisted design and performance analysis of fin type phase change hot water storage tank

The numerical simulation of the fin-type phase-change hot water storage tank is carried out and the influence of different fin height and number of fins on the heat storage characteristics of paraffin wax/expanded graphite is explored by using ANSYS software in this paper. The results indicate that during the heat storage process, the closer to the copper tube and the fins, the faster the temperature change rate. The higher the fin height, the faster the temperature change rate at the same measuring point. At the same time, the increase in the number of fins is not positively correlated with the temperature rate of each measuring point.
