Cell phones don't have refrigeration.
Because there is no refrigeration device installed inside the phone, there is no refrigeration function set.
Mobile phones mainly reduce the temperature by heat dissipation, such as the use of heat sinks, fans and other methods to solve the problem of overheating.
If you need to cool down, you can use external heat dissipation devices such as heat dissipation stickers. However, it should be noted that these external devices may affect the normal use of the phone. In recent years, some manufacturers have launched some mobile phones equipped with liquid cooling cooling systems to further improve the heat dissipation effect. However, these liquid cooling systems only achieve the purpose of heat dissipation through heat transfer, and not the real sense of refrigeration. Therefore, for the vast majority of mobile phones, they do not have refrigeration function, need to pay attention to reasonable use to avoid overheating problems.
