Cold chain transportation refrigerator based on phase change refrigeration

Abstract

The invention discloses a cold chain transportation refrigerator based on phase change refrigeration. The refrigerator comprises a refrigerator body, a box cover, a main cold storage plate, a heat insulation pulling plate and a plug, wherein a metal partition is arranged at the lower part, a standby interlayer is arranged below the metal partition, a standby cold storage plate is arranged in the standby interlayer, and a top placing groove and a bottom placing groove are also formed in the top and the bottom of the standby interlayer; the box cover covers the refrigerator body and is also connected with the refrigerator body through lock catches; the main cold storage plate is arranged on the lower surface of the box cover and comprises a cold storage agent filling box and a refrigerant, aplurality of outward bulging cold storage cells are arranged at the bottom of the cold storage agent filling box and communicated with the inside of the cold storage agent filling box, and the refrigerant is placed in the cold storage agent filling box and the cold storage cells; the heat insulation pulling plate and the plug are connected through a connecting plate. According to the cold chain transportation refrigerator, the target temperature can be quickly reached, the space occupancy rate is low, and refrigeration time can also be prolonged.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a cold chain transport refrigerator based on phase change refrigeration. Background technique [0002] As a small cold chain transportation tool, the refrigerated incubator plays a very important role in the transportation of medicines, vaccines and some light-weight foods. It is easy to carry, small in shape and simple in structure. Traditional insulated refrigerators use ice packs to refrigerate items. The frozen ice packs are placed in the refrigerator and absorb the temperature inside the refrigerator through a phase change reaction, thereby achieving the purpose of refrigeration. However, the ice pack takes up a lot of space, which greatly reduces the effective space utilization rate of the refrigerator. The refrigeration temperature is generally 0°C, which cannot meet the temperature requirements of some medicines. [0003] There are also some refrigerators that fill...

AI Technical Summary

Problems solved by technology

However, the ice pack takes up a lot of space, which greatly reduces the effective space utilization rate of the refrigerator. The refrigeration temperature is generally 0°C, which cannot meet the temperature requirements of some medicines.

[0003] There are also some refrigerators that fill the cold storage plate with phase change materials instead of ice packs, which solves the problem of different temperature requirements, but the bottom of the traditional cold storage plate is a smooth flat plate structure with a small surface area, which cannot Cooling down as quickly as an ice pack, the cold storage plate placed in the box meets the size requirements of the box, and its charge is limited, which leads to a reduction in the refrigeration and heat preservation time
