In order to research the competence of the copper foam/low-melting-point alloy (LMPA) composite material to recover to the initial state in the intermittent exothermic working environment and the influence of the addition of copper foam with different porosity on the solidification exothermic process, this paper compares and analyzes the solidification exothermic process of 47 alloys and n-tricosane before and after compositing with copper foam through numerical simulation, and adjusts the porosity of the copper foam/47 alloy composite material to calculate the temperature change curve of the simulation chip temperature during the solidification exothermic process. The results show that the addition of copper foam can promote the solidification process of the two types of materials, and the time of the simulation chip to recover to the target temperature is shortened by 6.6% and 47.7%. Due to the difference in volume latent heat value, the copper foam/47 alloy needs to release more heat during solidification, and it takes longer to recover to the target temperature, which is 1.52 times that of the n-tricosane composite. With the increase of porosity, the time that is taken for the composite phase change material to return to room temperature does not change much. Considering the influence of porosity on the thermal control process of phase change, comprehensive consideration should be given to actual use.
