Energy storage device

Abstract

The invention provides an energy storage device. The energy storage device comprises a shell (121) and a heat exchanger (123), wherein a space for containing a phase change material (122) is defined in the shell (121); the heat exchanger (123) is arranged in the space, is used for heat exchange with the phase change material (122) and comprises at least one group of heat exchange units; each heatexchange unit comprises a heat exchange body (125) and a heat exchange reinforced part (126); and the heat exchange reinforced part (126) is used for reinforcing the heat conduction of the phase change material (122) and the heat exchange body (125). According to the energy storage device, the phase change material is used for storing and releasing cooling capacity and breaks away from a power supply to maintain the refrigeration environments of heat preservation equipment; a power source is not needed; the power source-free refrigeration is realized; the heat exchange reinforced part of the energy storage device enlarges the contact area of the phase change material and the heat exchanger, so that the energy storage device uniformly releases cold energy; and the heat preservation equipment has little temperature fluctuation and accurate temperature control, reduces the rate of damage caused by corrosion and effectively ensures the quality of goods.

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 refrigeration unit, and the other is to install a cold storage unit capable of releasing cold energy in the box body. plate. The cold storage plate contains the phase change material,...

AI Technical Summary

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
