Slow-release cold accumulation system and slow-release cold accumulation bag

Abstract

The embodiment of the invention provides a slow-release cold accumulation system and a slow-release cold accumulation bag. The slow-release cold accumulation system comprises a slow-release system anda cold accumulation system, the slow-release system comprises a slow-release agent and a refrigerant dispersed in the slow-release agent, and the freezing point temperature of the slow-release agentis higher than that of the cold accumulation system. Due to the fact that the freezing point between the slow-release system and the cold accumulation system has temperature difference, when the environment temperature rises, due to the fact that the freezing point of the cold accumulation system is lower than that of the slow-release system, the cold accumulation system is firstly melted, and cancontinuously absorb environment heat in the melting process, so the cooling and cold accumulation effects are achieved. When the temperature rises to the freezing point temperature of the slow-release system, the slow-release system begins to be melted, and at the moment, the refrigerant dispersed in the slow-release system makes contact with the molten cold accumulation system to generate an endothermic reaction, so that environmental heat is further absorbed, and finally, the continuous cooling and cold accumulation effects are achieved. Compared with ice bags in the prior art, excessive instant temperature drop caused by dissolution and heat absorption can be prevented, and the refrigeration time is effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a slow-release cold storage system and a slow-release cold storage bag. Background technique [0002] In the absence of a cold source, for fresh food, biological agents and other products that require refrigerated transportation, ice packs are usually used for refrigerated insurance. [0003] CN209512351U discloses a kind of anti-crack ice pack, this ice pack comprises No. 1 textile material layer, No. 1 rubber layer is fixedly installed on the outer surface of the lower end of No. 1 textile material layer, No. 1 plastic layer is fixedly installed on the lower end outer surface of No. 1 rubber layer, a No. 2 plastic layer is fixedly installed on the outer surface of the lower end of the No. 2 plastic layer, No. 2 rubber layer is fixedly installed on the lower end outer surface of the No. 2 plastic layer, and No. 2 textile material layer is fixedly installed on t...
