Description

technical field [0001] The invention belongs to the technical field of data center heat dissipation, and in particular relates to a system, method and device for adjusting the flow rate of a parallel branch of a two-phase cold plate liquid cooling system. Background technique [0002] With the development of cloud computing and big data, the data center is developing rapidly, and there are changes to the PUE requirements of the data center. In order to meet the growing demand for computing power, the power density of a single cabinet is getting higher and higher. In the next five years, 40kW cabinets will become the mainstream, and when the power density of a single cabinet reaches 20kW, the air-cooled system is close to its cost-effective cooling limit. In this context, the heat dissipation technology of liquid-cooled data centers with low PUE and high heat dissipation density has emerged as the times require. Two-phase cold plate liquid cooling uses the latent heat of vap...
