Problems solved by technology

[0004] Although there are ice packs with various structures and functions in the prior art, the current ice packs can only release cold through the phase change of the cold storage agent, or release the cold instantly through the endothermic reaction of dissolution, and cannot control the endothermic reaction of dissolution to a specific level. Timing, the control of reaching the temperature for a long time is below the freezing point of the cooling agent

Abstract

The embodiment of the invention provides a dissolving heat absorption system with controllable reaction time and a cold accumulation bag. The dissolving heat absorption system comprises a refrigerantand a cold accumulation system; the cold accumulation system comprises water and a freezing point regulator dissolved in the water, and the freezing point of the cold accumulation system can be controlled through the concentration of the freezing point regulator. During use, the cold accumulation system with the corresponding freezing point can be blended by adjusting the concentration of the freezing point regulator; when the environment temperature is lower than the freezing point of the cold accumulation system, the cold accumulation system plays a role in cooling; when the environment temperature rises to the freezing point of the cold accumulation agent, the cold accumulation agent begins to be melt, and heat is absorbed through phase change; meanwhile, molten water in the cold accumulation system makes contact with a refrigerant to generate an endothermic reaction, environment heat is further absorbed, finally, the effect of continuous cold accumulation and cooling is achieved, and the refrigeration time is effectively prolonged.
