Problems solved by technology

These cooling capacity replenishment methods are relatively simple, the replenishment efficiency is low, the time is long, and the cost is high
In addition, the phase change material in the cold storage plate releases the cold energy unevenly, which makes the temperature fluctuation in the insulation equipment large, the temperature control is inaccurate, and the cargo damage rate is high

Embodiment 1

[0070] In Embodiment 1, the first transmission device includes an external circulation pump 21 and an external circulation pipeline 22 , and the second transmission device includes an internal circulation pump 24 and an internal circulation pipeline 25 . The external circulation pump 21 outputs the cooling medium Z that meets the predetermined requirements from the first storage unit 231 through the external circulation pipeline 22 for use, and transfers the used cooling medium Y to be refrigerated to the second storage unit 232 through the pipeline . There is a refrigeration unit 26 on the transmission path of the second transmission device, and the internal circulation pump 24 receives the cooling medium Y to be refrigerated from the second storage unit 232 , and sends the cooling medium Y to be refrigerated into the refrigeration unit 26 through the internal circulation pipeline 25 Refrigeration is performed so that the temperature of the cooling medium meets the predetermi...

Abstract

The invention provides an energy storage device. The energy storage device comprises a shell (121), a phase-change material (122) and a heat exchanger (123), wherein the shell (121) defines the spacefor containing the phase-change material (122); the heat exchanger (123) is used for carrying out heat exchanging on the phase-change material (122); the heat exchanger (123) comprises at least one set of heat exchanging units, and each heat exchanging unit comprises a heat exchanging body (125) containing a cold-loading medium; and the shell (121) comprises a heat dissipating reinforcement part (124), and the heat dissipating reinforcement part (124) dissipates the energy transmitted to the shell (121) by the phase-change material (122). According to the energy storage device, the contact area of the energy storage device and the space in a heat insulation box is increased through the heat dissipating reinforcement part, heat insulation equipment releases cold energy uniformly, the temperature fluctuation degree is small, the temperature control is precise, the cargo corrosion damage rate is reduced, and the cargo quality is effectively guaranteed.

Description

technical field [0001] The invention relates to an energy storage device, in particular to an energy storage device for heat preservation equipment. Background technique [0002] A cold chain container is an insulated transportation device used to transport temperature-sensitive goods. It is necessary to use the heat preservation device to keep the products in the box within a certain temperature range during transportation, and to ensure the quality of the goods without changing the temperature and humidity of the surrounding environment. [0003] In order to keep the temperature inside the container and other thermal insulation transportation equipment constant within a predetermined range, there are mainly two thermal insulation methods in the prior art. One is to equip the box body with a cooling device with a generator, and the other is to install a cooling device capable of releasing cooling in the box body. Amount of cold storage plate. The cold storage plate contai...
