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

Embodiment 1

[0046] Such as Figure 2-9 As shown, this embodiment provides an integral cold storage plate, including a cold storage plate shell 110 and a longitudinal partition 180 arranged in the cold storage plate shell 110, and the cold storage plate shell 110 and the longitudinal partition 180 are integrally drawn by a profile The stretch forming process stretches into a uniform overall structure.

[0047] The longitudinal partition 180 isolates a part of the space in the cold storage plate shell 110 as the cold charging channel 130 for the brine 500 to pass through, and the rest of the space is used as the cold storage liquid chamber 120 filled with the cold storage liquid 400 . The longitudinal partition 180 is composed of a channel partition 181 forming the cold charging channel 130 , and a connecting rib 182 connected between the channel partition 181 and the cold storage plate housing 110 and between different channel partitions 181 .

[0048] The cold storage liquid cavity 120 i...

Embodiment 2

[0054] Such as Figure 10-16 As shown, this embodiment provides an insulated container, which includes a container body 200 with an insulated box wall 210 , and a cold storage plate device and a cold charging pipeline system 300 are arranged in the container body 200 .

[0055] The heat insulation box wall 210 has a sandwich structure, including an inner wall plate 211, an outer wall plate 212 and an insulating layer 213 sandwiched between them. The insulating layer 213 is made of polyurethane foam material and has the function of heat preservation and heat insulation. The heat insulation box wall 210 comprises a top plate 220 , a side plate 230 , a bottom plate 240 , a front wall 250 and a box door 260 according to specific positions.

[0056] The cooling pipeline system 300 is arranged near the wall surface of the heat insulation box wall 210 , and includes a brine inlet pipe 330 , a brine return pipe 340 and a cooling interface. The cooling interface includes a cooling liq...

Embodiment 3

[0060] This embodiment provides a method for charging and cooling the insulated container in Embodiment 2, including two processes of charging and cooling, wherein:

[0061] Before the insulated container is transported, the cold storage plate 100 in it is pre-charged by the cold charging station. The specific cold charging steps are as follows: the brine 500 from the cold charging station enters the brine inlet 140 into the brine inlet pipe 330 reaches the liquid storage tank 160 at one end of the cold storage plate 100; then divides into a plurality of branches and enters the cold charging channel 130 of each cold storage plate 100, and cools the cold storage liquid 400 in each cold storage plate 100, so that the temperature of the cold storage liquid 400 is reduced to a corresponding level. Phase change occurs at or below the phase change point to store cold storage capacity; after the brine 500 exchanges heat in the cooling channel 130, it flows out of the cooling channel 1...

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.
