Description

Technical Field

[0001] The utility model relates to the technical field of batteries, and in particular to an energy storage battery pipeline heat dissipation system and an energy storage system. Background Art

[0002] As the heat generation power of energy storage gradually increases, air cooling cannot meet the heat dissipation requirements. Liquid cooling requires complex and numerous system pipelines for cooling capacity. The increase in pipelines will increase the complexity of installation and the possibility of leakage.

[0003] In some related technologies, when the return liquid pipes are all at the top, leakage will occur, and the liquid will flow to the battery cluster, causing a short circuit risk. In some other related technologies, the battery cluster corresponds to a group of inlet and outlet pipes. This method results in a large number of pipes, high pipe pressure, and high pump cost. The simple schematic diagram of a single-tube bottom-in and top-out pipe has practical feasibility issues. At the same time, the return liquid pipe will flow to the battery cluster after leaking at the top, causing a short circuit risk. Therefore, as the number of pipes increases, the difficulty of flow distribution will increase, the pressure of the water pump will increase, and the possibility of leakage risk will increase.

[0004] Therefore, how to solve the problem of too many pipelines is a technical problem that needs to be solved urgently in this field. Utility Model Content
