Abstract

The embodiments of the present invention provide a slow-release cold storage system and a slow-release cold storage bag. The slow-release cold storage system includes a slow-release system and a cool-storage system. The slow-release system includes a slow-release agent and a refrigerant dispersed in the slow-release agent. The freezing point temperature of the release agent is higher than the freezing point temperature of the cold storage system. Due to the temperature difference between the freezing point of the slow-release system and the cold storage system, when the ambient temperature rises, the cold storage system will melt first because the freezing point of the cold storage system is lower than that of the slow-release system. role. When the temperature rises to the freezing point of the slow-release system, the slow-release system begins to melt. At this time, the refrigerant dispersed in the slow-release system contacts with the melted cold storage system to undergo an endothermic reaction, thereby further absorbing environmental heat, and finally With the effect of continuous cooling and cold storage, compared with the ice packs in the prior art, it can prevent the temperature from melting and absorbing heat to cause an excessive instantaneous drop in temperature, and effectively prolong the refrigeration time.
