Cryogenic slow-release portable cold source device with supercooling protection and using method thereof

Abstract

The invention relates to a cryogenic slow-release portable cold source device with a supercooling protection function and a using method thereof. The cryogenic slow-release portable cold source device with the supercooling protection function and the using method thereof aim at solving the technical problem that an existing portable cold source device cannot meet the comprehensive requirements for on-site refrigeration, cryogenic slow release and the like in a field unguaranteed scene. According to the device, normal-temperature components such as ammonium chloride, barium hydroxide and sodium chloride are adopted, the composite process of chemical heat absorption and phase change heat absorption is utilized, the comprehensive efficiency of deep cold storage and slow-release refrigeration is achieved, the device is a portable device capable of providing long-time deep cooling conditions, the problems that in the prior art, on-site refrigeration cannot be achieved, deep cooling cannot be achieved, and portability and standby application cannot be achieved are solved; starting is achieved through mechanical operation, low-temperature guarantee and medium filling are not needed, and the problems that in the prior art, the guarantee requirement is high, and operation is complex before use are solved; and an isolation structure is designed on the basis of a gas product in the chemical heat absorption process, and a supercooling protection function is achieved.

Description

technical field [0001] The invention relates to a cold source device, in particular to a cryogenic slow-release portable cold source device with overcooling protection and a use method thereof. Background technique [0002] The portable cold source is used for low temperature maintenance under conditions without cold chain support and field conditions, and is widely used in fresh food transportation, medical rescue and other scenarios. From the perspective of the requirements of typical scenarios, the design of portable cold sources mainly focuses on technical performance such as cold storage capacity per unit weight, minimum stable temperature, and performance such as overcooling protection and start-up mode. [0003] Existing portable cold sources can be divided into unsupported types such as rechargeable refrigerators, and dependent types such as ice packs, ice-salt baths, and small plug-in refrigerators. [0004] Rechargeable refrigerators adopt electric drive semicondu...
