Description

Technical Field

[0001] The utility model relates to the field of energy storage liquid cooling systems, in particular to a multi-circuit system connector. Background Art

[0002] The energy storage market is poised to continue its explosive growth. To effectively promote the absorption of renewable energy, large-scale, high-capacity energy storage power stations are accelerating their deployment. As a crucial component of energy storage systems, thermal management systems are benefiting from the growth of installed energy storage capacity, and the energy storage temperature control market is expected to continue expanding. To capture this market share, continuous breakthroughs in technological research and innovation are essential. This patented solution develops three-way and four-way connectors with drainage functions to reduce costs and improve energy storage efficiency. These connectors connect to the NW40 pipeline, presenting a novel solution for the flexible assembly of energy storage liquid cooling systems. Suitable for high-flow, high-power, multi-circuit water cooling systems, they offer more reasonable flow distribution, more precise battery thermal management and temperature control, and are therefore more suitable for market development.

[0003] However, the energy storage industry currently has a variety of connection methods. This product is a flexible connection for the NW40 product and can ensure the maximum flow circulation of the liquid cooling system pipeline. However, the 40 pipeline has fewer matching connectors and cannot be flexibly used in the field of energy storage liquid cooling systems.

[0004] The greater the coolant flow rate, the more heat is circulated out in the same period of time, so the greater the flow rate, the better the cooling effect. However, the coolant temperature difference between the inlet and outlet of the battery pack at different distances from the water cooler inlet is different. The farther the distance, the greater the temperature difference, the smaller the heat transferred from the battery to the coolant, and the poorer the cooling effect.

[0005] Therefore, it is necessary to provide a multi-circuit system connector to solve the above technical problems. Utility Model Content
