In recent years, the industry demand for electric power has been rapidly increasing, and advanced nations have overcome the shortage of power by various ways. Recently, as the use of environmentally friendly energy such as geothermal and solar heat has been increased, interest in heat storage systems has been increasing in related industries, but research on cooling capsules, which is a core component of heat storage system, is insufficient. Therefore, in this paper, we analyzed the mode and cause of the failure of the cooling capsule, and confirmed that the internal pressure of 130% higher than that of the existing product was maintained by the optimal design.
