What is a liquid cold plate

Liquid-cooled cold plates are typically used in high heat flux or high power electronics cooling applications. The cold plate is responsible for absorbing heat from the equipment and transferring it into a single-phase liquid coolant, which circulates through the internal channels of the plate, and then discharges it to a downstream heat sink.

Liquid cooling plate cooling power requirements

The heat dissipation power is large, and the excess heat generated during the working process of the power battery can be exported in time to avoid the occurrence of excessive temperature rise;

Liquid cooling plate cooling power requirements

Liquid cold plate reliability requirements for battery packs

High reliability, working in road vehicle environment, vibration, shock, high and low temperature alternating environment, are relatively harsh working conditions for most products, and the power battery voltage is often hundreds of volts, coolant leakage is a serious problem, even if you use Coolant with good insulation performance, but after encountering external impurities, the insulation performance will be reduced immediately, therefore, the reliability of cold plate sealing is very important;

Liquid cold plate reliability requirements for battery packs

Liquid cooling plate heat dissipation design of battery pack

The heat dissipation design is precise to avoid excessive temperature difference in the system. This is due to the performance requirements of the lithium battery itself. The performance and aging of the battery are closely related to the working temperature;

Liquid Cooling Plate Weight Requirements for Battery Packs

The weight of the cold plate has strict requirements, which comes from the pursuit of energy density in the power battery system. The cooling system that seriously reduces the energy density of the system is completely unacceptable to both customers and designers.

Frequently Asked Question

Do you have any question?

Liquid cold plates are responsible for transferring heat from surfaces with high thermal loads to the fluids used in liquid cooling systems. The performance of these components is critical to the overall effectiveness of the liquid system.

Cold plates are usually made of metal with flow paths machined in them for the heat transfer fluid to flow through. As the plates absorb electrical waste heat, they use liquid cooling to dissipate it through the flow path.

Cold plates provide local cooling by transferring heat from the equipment to a liquid that flows to a remote heat exchanger and dissipates into the environment or another liquid in a secondary cooling system.
