Liquid Cooling Energy Storage Sheet Metal

Can liquid metals be used as heat transfer fluids in thermal energy storage?

The use of liquid metals as heat transfer fluids in thermal energy storage systems enables high heat transfer rates and a large operating temperature range (100°C to >700°C, depending on the liquid metal). Hence, different heat storage solutions have been proposed in the literature, which are summarized in this perspective.

What are liquid metal thermal energy storage systems?

Liquid metal thermal energy storage systems are capable of storing heat with a wide temperature range and have, thus, been investigated for liquid metal-based CSP systems 3, 4 and in the recent past also been proposed for industrial processes with high temperature process heat. 5

Can liquid metal be used as a heat storage medium?

The perspective is focused on thermal energy storage systems using liquid metal as heat transfer fluids, but not necessarily as heat storage medium. For the latter, the interested reader is referred to several reviews available on latent heat storage systems using liquid metal as a phase change material. 6, 7

Which liquid metals can be used in thermal energy storage systems?

Based on their liquid temperature range, their material costs and thermophysical data, Na, LBE, Pb, and Sn are the most promising liquid metals for the use in thermal energy storage systems and evaluations in section 4 will focus on these four metals.

Are liquid metal based cooling systems a good thermal management material?

Liquid Metal–Enabled Combinatorial Heat Transfer Science Liquid metals have been approved to be a class of excellent thermal management materials, and many liquid metal–based cooling systems have thus been enabled and investigated over the past few years.

Which metals are used in heat storage systems?

In this literature review, the works are split into heat storage systems using alkali metals, such as Na or NaK as heat transfer fluids and those using heavy liquid metals, such as Pb and lead-bismuth.
