What are the objectives of a liquid based cold plate?

Objective functions and constraints 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 cooling performance of cold plate?

The cooling performance of the cold plate varies with the mass rate of flow of the coolant. The maximum temperature and temperature difference of the battery decrease with the increase of mass flow rate and tend to stabilize after 0.75 g·s −1. Fig. 17. The cooling performance of the cold plate varies with the mass rate of coolant flow. 3.3.

How is a liquid cooling system based on a cold plate?

In summary, the liquid cooling system is mainly achieved based on a cold plate, while the cooling efficiency of the cold plate directly depends on the internal channel structure. It was elucidated that a practical and feasible channel structure can be derived based on biological structural features.

How does a butterfly shaped battery cooling plate work?

The primary explanation is that the branch channels in the center of the leaf-shaped channel flow to both sides, which can evenly distribute the coolant and lower the temperature difference on the battery surface, enhancing overall cooling performance. Fig. 8 (d) displays the battery temperature using the butterfly-shaped channel cold plate.

What is the difference between indirect contact and liquid-based cooling plate?

In contrast, indirect contact, which separates coolant from battery using cold plates or tubes, has become mainstream in real applications . Nevertheless, the superiority of hydrothermal performance of liquid-based cooling plate is highly dependent on the flow parameters and topology.

Does a butterfly-shaped channel cold plate reduce pressure loss?

However, some complex bionic structures increase the energy consumption of the liquid cooling system due to more significant pressure loss. Thus, to improve the cooling performance and reduce the pressure loss of the cold plate, a butterfly-shaped channel cold plate based on the shape and structure of butterfly wings was proposed in this paper.
