In today's society, energy consumption is growing at an alarming rate. Because of the huge economic benefits brought by traditional industries such as non renewable energy and fossil fuel power generation, people have to study them. The phase-change heat storage materials are widely used in the condensation heat storage due to their high temperature, low density and environmental protection. This paper considers the advantages, disadvantages and application scope of the new energy storage equipment based on the phase-change storage characteristics, and proves through experiments that under certain conditions, the appropriate solid-liquid ratio and the degree of substitution of different components are conducive to improving the performance of the composite storage heat exchanger. In this paper, a new composite phase change material for cold storage and heat storage is tested. The test results show that, because the carbon nanotubes added in the composite phase change material have no latent heat contribution in the whole phase change process, the phase change enthalpy of the composite phase change material will inevitably decrease with the increase of the carbon nanotube mass fraction.
