Abstract

The invention relates to a constant temperature control device, in particular to a temperature control device for an electrolyte storage device of a vanadium redox battery. The electrolyte storage device is controlled at constant temperature by using a cyclic temperature control method, the optimum working temperature of the whole system is effectively ensured, radiating area is large, the occupation area of an energy storage system is saved by using an internal space of a liquid storage tank, and the system can operate safely, stably and reliably. The temperature control device is novel in design and reasonable in structure, the working temperature of a control system can be controlled in real time, the constancy of temperature is maintained, and the system can operate safely and reliably. The temperature control device can be conveniently integrated in the energy storage system of the vanadium redox battery, large-scale engineering application of the energy storage system is realized, and the stability of the system is effectively improved.

Description

technical field [0001] The invention relates to a constant temperature control device, in particular to a temperature control device used in an electrolyte storage device of an all-vanadium redox flow battery. Background technique [0002] Vanadium Redox Batty (VRB for short) is a new type of clean energy storage device with technical advantages such as long life, safety and environmental protection, independent design of power capacity, low operation and maintenance costs, and support for frequent high-current charging and discharging. . [0003] Due to the fact that the all-vanadium redox flow battery system will generate a certain amount of heat during the high-current discharge process, the heat will continue to accumulate with the prolongation of the system's working time, resulting in a gradual increase in the temperature of the circulating electrolyte and a decrease in the stability of the electrolyte, thereby affecting energy storage. normal operation of the system....
