UNIFORM FLOW DEVICE AND METHOD FOR BATTERY ENERGY- STORAGE LIQUID COOLING SYSTEM

摘要

A device for flow equalization of a liquid cooling system of battery energy storage comprises a plurality of battery modules in parallel, each of the battery modules being connected to the liquid cooling system, and being provided with a cooling-fluid feeding inlet, wherein a throttle pipe is provided in the feeding inlet, the throttle pipe is provided with a flow restriction orifice, and the cooling fluids that enter the feeding inlets are adjusted by the throttle pipes to equal pressures. The device can enable the liquid cooling system to more uniformly distribute the flow rates of the cooling fluids among battery sub-packs or modules, thereby ensuring that the battery system operates at more uniform environmental temperatures, to reduce the difference in the performances of the modules, and prolong the service lives of the batteries.
