Liquid cooling plate energy storage

What is a liquid based cold plate?

For a liquid-based cold plate, the primary goal is to maximize the heat transfer rate and minimize the flow resistance through optimizing the channel structure. In addition, thermal uniformity is another key factor, which cannot be neglected for battery thermal management.

What is the multi-objective optimization method for liquid cooling plates?

This study aims to investigate the multi-objective optimization method for liquid cooling plates in automotive power batteries. The response surface method and NSGA-II were combined to optimize the temperature of the battery system under liquid-cooled conditions and the internal pressure of the liquid-cooled plate.

Is a liquid-cold plate effective in moving asymptotes?

Use of cooling plate has proved to be an effective approach. In the present study, we propose a novel liquid-cold plate employing a topological optimization design based on the globally convergent version of the method of moving asymptotes (GCMMA) method.

How does a cold plate work?

Based on prior study , the cold plate is separated into many short flow paths and is positioned on the bottom surface of batteries. During operating process, the coolant flows down through channels and exchanges excess battery heat with the solid walls of cold plate. Fig. 1.

Does battery heat generation affect to design of cold plate?

In 2022, Vichapol et al. considered the effect of battery heat generation on TO design of cold plate. The channels formed at high heat load exhibited complex flow paths, but they had good suitability for low charge/discharge rates.

What is a variable heat generation QH of cold plate?

Nevertheless, it remains challenging to accurately characterize the complex physical information in TO model. As a result, this model introduces a variable heat generation QH of cold plate, which is analogous to the heat dissipated by fluid at steady-state.
