Stimulated self-refrigeration low-temperature ice salt bag

Abstract

The invention relates to an ice bag, in particular to a stimulated self-refrigeration low-temperature ice salt bag. The invention aims at solving the technical problem that the cold accumulation capacity of an existing ice salt bag is limited to a certain extent due to the fact that textile cloth is adopted for physical isolation of ice and sodium chloride, and provides the stimulated self-refrigeration low-temperature ice salt bag. A sealed ice salt bag structure is designed through the steps of water drop packaging, salt particle premixing and the like, a low-temperature condition can be rapidly prepared under the conditions of no water injection and no water immersion, and the defects that water injection or water immersion is needed before a multi-component chemical ice bag is used, and the sealing failure risk is large are overcome; self-refrigeration can be achieved through short-time low-temperature stimulation, and the problem that daily use guarantee is difficult due to the fact that deep cold accumulation of the multi-component chemical ice bag consumes long time is solved; and deep cold accumulation is achieved through a phase change mechanism of a mixture of the sodium chloride and ice, the cold accumulation capacity of the stimulated self-refrigeration low-temperature ice salt bag is superior to the cold accumulation capacity of a traditional water-based ice bag, and the material cost of the stimulated self-refrigeration low-temperature ice salt bag is lower than the material cost of the multi-component chemical ice bag.

Description

technical field [0001] The invention relates to an ice bag, in particular to a stimulated self-cooling low-temperature ice salt bag. Background technique [0002] The ice pack has a built-in cold storage working medium, which can provide low temperature conditions for a certain period of time, and is widely used in medical treatment and fresh food logistics and other industries. Existing ice packs are generally divided into water-based traditional ice packs and multi-component chemical ice packs. [0003] The water-based ice bag has a low cold storage capacity and the working fluid freezes below zero. The volume expansion during the freezing process is likely to cause failures such as bag swelling and leakage, and its practicability is poor. Multi-component chemical ice packs use aqueous solutions of inorganic salts, polymer gels and other compounds as working fluids, and their cold storage capacity and refrigeration capacity are superior to traditional ice packs that use w...
