A refrigerator for cold chain transportation

Abstract

The invention discloses a refrigerator for cold chain transportation, which relates to the technical field of cold chain transportation. It includes a refrigerated box body, and the bottom end inside the refrigerated box body is fixedly installed with a circulating cooling mechanism; the circulating cooling mechanism includes a water storage tank and a water pump, and the bottom of the water storage tank is in phase with one side of the bottom end inside the refrigerated box body. fixed. The invention transports the ice water in the water storage tank to the inside of the cooling pipe through the water pump, and then achieves the function of adjusting the temperature of the ice bag placed in the device through the temperature-penetrating plate, and realizes the complete control of the temperature of the placed ice bag with a simple mechanical structure. The maintenance of the refrigerating box reduces the speed of temperature change in the refrigerator; in addition, the ventilation pipes, the temperature-permeable plates, the air outlet protrusions and the interior of the placing box are connected to realize the direct conduction of the cold air in the water storage tank to the placing box. The arrangement inside the box realizes the direct cold chain storage of the goods inside the box, and improves the cooling effect of the refrigerated box.

Description

technical field [0001] The invention relates to the technical field of cold chain transportation, in particular to a refrigerator for cold chain transportation. Background technique [0002] Cold chain transportation refers to the transportation in which the transported goods are always kept at a certain temperature in the whole process of transportation, whether it is loading and unloading, changing the transportation mode, changing the packaging equipment, etc. Cold chain transportation has good preservation effect and long preservation period, so it is widely used in the transportation of food and pharmaceutical industries, and refrigerated box is one of the equipment of cold chain transportation. Cold chain transport equipment. [0003] The Chinese invention patent publication number CN110902152A discloses a refrigerator for cold chain transportation. By fixing the ice bag on the inner side wall of the cover, the ice bag is separated from the items, which not only reduc...

AI Technical Summary

Problems solved by technology

[0004] First: When the refrigerator is actually used, the temperature of the ice pack is passed with time in actual use, so the ice pack has a time limit for adjusting the internal temperature of the refrigerator;

[0005] Second: The refrigerator only relies on ice packs to maintain the temperature, and considering that the thermal insulation of the ice packs is lost over time, the refrigerator cannot guarantee that its internal temperature has been maintained at a stable value
