Insulated container based on integral cold storage plate and cold filling and cold supply method of insulated container

Abstract

The invention discloses an insulated container based on an integral cold storage plate and a cold filling and cold supply method of the insulated container. The insulated container comprises a container body provided with a heat insulation container wall, and a cold storage plate device and a cold filling pipeline system are arranged in the container body. The cold storage plate device comprises at least one cold storage plate. Each cold storage plate comprises a cold storage plate shell and a longitudinal partition plate connected with the cold storage plate shell into a whole. One part is isolated out of the space in each cold storage plate shell by the corresponding longitudinal partition plate to serve as a cold filling channel, and the rest of parts of the space of each cold storage plate shell serve as a cold storage liquid cavity. The cold filling pipeline system comprises a secondary refrigerant inlet pipe, a secondary refrigerant return pipe and a cold filling connector. The cold filling channels of all the cold storage plates are connected between the secondary refrigerant inlet pipe and the secondary refrigerant return pipe. By means of the cold filling and cold supply method, a ground movable or fixed cold filling station is utilized for filling the cold storage plates with cold, cold storage liquid in the cold storage plates stores cold of the maximum quantity, andsource-free refrigerating in the transporting process is achieved.

Description

technical field [0001] The invention relates to an insulated container, in particular to an insulated container based on an integral cold storage plate and a cold charging and cooling method thereof. Background technique [0002] Refrigeration and freezing of food has always been an energy-intensive industry due to its large volume and wide range. To make the food cold chain sustainable development, it is necessary to study the energy-saving and consumption-reducing technology of cold chain logistics, and the phase change cold storage technology is an excellent direction of development. The application of phase change cold storage technology in cold chain transportation is to use the principle of phase change energy storage to rationally allocate materials with different phase change temperatures according to different temperature requirements of cold chain transportation to achieve the effect of phase change cold storage and heat storage. The technology has broad applicati...

AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned cold storage plate, the heat exchange coil is installed on the cold storage plate shell by splicing. The process is relatively complicated, and there is still a risk of leakage of the heat exchange coil during use, and the heat exchange coil cannot be repaired separately after leakage tube, only the cold storage plate can be replaced as a whole, and the maintenance cost is relatively high

Secondly, the cold storage agent mainly transfers heat through contact with the heat exchange coil. Although the heat transfer efficiency is high, it is limited by the heat transfer area of ​​the heat exchange coil. It takes a long time for the cold storage liquid in the cold plate to complete the phase change and freeze (generally 8 to 10 hours), thus affecting its turnover efficiency
