Description

Phase change material cooling patch Technical Field The utility model relates to the technical field of phase change materials, in particular to a phase change material cooling patch. Background The phase change heat storage technology is widely applied in the field of heat energy management due to the high energy density and the heat storage and release characteristics of approximate constant temperature. The core principle of a Phase Change Material (PCM) based cooling structure is to use PCM to absorb and store a large amount of latent heat at a phase change point (usually solid-liquid transition), thereby preventing or slowing down the temperature rise of a protected area. The heat storage capacity of a phase change material is mainly dependent on its latent heat of phase change and the quality of the material. Latent heat of phase change refers to the heat absorbed or released during phase change, and the volume of the material determines the total amount of phase change material that it can store. Thus, the greater the volume, the more ‌ heat can be stored, the greater the amount of stored heat of the phase change material is proportional to its volume. The total mass of a material directly affects the total amount of heat that it can store. The greater the mass, the greater the heat storage. However, when the thickness of the heat storage unit (phase change material/phase change material cooling patch) is increased, heat is difficult to rapidly transfer to the inner area, so that the heat storage rate is obviously reduced, and the practicability of the large-capacity heat storage cooling patch is severely restricted.
