Problems solved by technology

However, after this method changes the total flow, the resistance will be redistributed, and the balance of the pipeline will be broken. At this time, the pipe diameter must be redesigned to obtain a better flow equalization effect.

Abstract

The invention provides a cooling pipeline for energy storage, a cooling method and an energy storage device.The cooling pipeline for energy storage comprises an annular inlet main pipe, an annular outlet main pipe and at least one cooling branch pipe, and the inlet ends of the cooling branch pipes are independently connected to the annular inlet main pipe; the outlet ends of the cooling branch pipes are independently connected to the annular outlet main pipe. The cooling medium enters and flows out of the cooling branch pipes through the annular inlet main pipe and the annular outlet main pipe, it is effectively guaranteed that the resistance of the cooling medium entering all the cooling branch pipes is similar, the temperature difference of batteries in the energy storage system is effectively reduced, and the service life of the batteries is prolonged.

Description

technical field [0001] The invention belongs to the technical field of energy storage devices, and relates to a cooling pipeline for energy storage, a cooling method and an energy storage device. Background technique [0002] With the continuous pursuit of high-rate charge and discharge in the energy storage industry, liquid cooling technology is a key direction of current energy storage electrothermal management technology. However, the current liquid-cooling technology mostly uses liquid-cooling plates to exchange heat for the cells, and the liquid-cooling pipelines are mostly in the form of different-path pipelines. There is a problem of uneven flow distribution in each cluster in the secondary pipeline. At the same time, the three-stage pipeline also has the problem of uneven flow distribution. The uneven flow distribution will cause deviation of the coolant flow into each liquid-cooling plate, resulting in different cell temperatures, increasing the temperature differe...
