Cold storage box and application method thereof

Abstract

The invention discloses a cold storage box and an application method thereof. The cold storage box comprises a box body and an adsorption part. A first cavity wall is arranged on the outer side of thebox body. A second cavity wall is oppositely arranged outside the first cavity wall. The space between the first cavity wall and the second cavity wall is an evaporation cavity. Water absorbing materials for adsorbing a refrigerant are arranged on the side, towards the evaporation cavity, of the first cavity wall. The adsorption part is provided with an adsorption cavity. The adsorption cavity communicates with the evaporation cavity through a heat exchange pipeline. A valve is arranged on the heat exchange pipeline. An adsorbent for adsorbing the refrigerant is arranged in the adsorption cavity. The water absorbing materials are arranged on the inner wall, close to the box body, in the evaporation cavity, when the refrigerant conducts evaporation and refrigeration from the water absorbing materials, the refrigerating amount transmitted into the box body through the refrigerant is maximal, the refrigerating amount utilization rate is increased, and the cold storage effect is improved.The cold storage box is reasonable in structure, convenient to use and capable of being widely applied to the technical field of cold chain transportation.

Description

technical field [0001] The invention relates to the technical field of cold chain transportation, in particular to a refrigerator and a use method thereof. Background technique [0002] It is reported that the total market value of products that require cold chain services in my country is expected to exceed 3 trillion yuan. If the cold chain cost is calculated at the most conservative 5%, the cold chain market will exceed 150 billion yuan, which shows the demand and development of my country's cold chain market. The space is huge. [0003] At present, the existing small portable refrigerators and their evaporation chambers generally adopt the following three technologies: [0004] 1. Compressor refrigeration technology [0005] Compressor refrigeration technology is widely used in stationary application refrigeration where the evaporator chamber is constructed as a flat wall chamber / heat exchanger combination. Due to the poor shock resistance, anti-vibration, and anti-til...

Problems solved by technology

This technology has disadvantages such as difficult temperature control, consumables, and inability to control refrigeration start-up, and poor recyclability

[0010] The deficiencies of these existing technologies have prompted the innovation of cold chain transportation technology, making it urgent to research and develop new low-temperature transportation and distribution equipment and new key components. For example, passive refrigerators are one of the main tools for cold chain logistics distribution. The performance of the evaporation chamber used greatly affects the overall performance of the passive refrigerator

Most of the existing evaporation chambers are ordinary flat-walled chambers, which have small heat transfer area, poor heat transfer efficiency, low temperature in the box, small effective storage space, and short average melting time, which limits cooling. The development of chain transportation
