Michael Ruscigno explains how Baknor helps to keep batteries and electronics cool with their liquid plates
The lifespan and efficiency of batteries and power electronics are highly dependent on temperature management. As these components become more powerful and compact, traditional air-cooling methods often struggle to prevent them overheating. This is where liquid cold plates step in, offering a superior thermal management solution.
Liquid cooling has become increasingly popular for dissipating heat in various applications, including batteries and power electronics.
How liquid cold plates work
A liquid cold plate is metallic and absorbs heat from a heat source, such as a battery pack or a power converter. It contains channels or microchannels through which a coolant flows, typically water or a water-glycol mixture. The cold plate absorbs heat from the heat source and transfers it to the coolant, which carries it away to a heat exchanger, where it is ultimately dissipated.
Features:
High thermal conductivity: liquid cold plates offer excellent thermal conductivity due to their direct contact with the heat-generating components, enabling efficient heat dissipation.
Compact design: cold plates are thin and lightweight, making them ideal for tight spaces in EVs, fuel-cell vehicles (FCVs) and other applications. Their compactness ensures efficient cooling without compromising the available space.
Reduced risk of thermal runaway: liquid cold plates enhance safety and reliability by preventing overheating, and in battery applications, avoiding thermal runaway is critical to prevent catastrophic failure.
Energy efficiency: liquid cooling plates require less power than traditional, air-cooling solutions. Unlike high-speed fans used in air cooling, liquid cooling operates at lower flow rates, resulting in energy savings and reduced electricity consumption.
Compatibility with coolants: liquid cold plates are compatible with various coolants, including water and water-glycol mixtures. This flexibility allows for customisation, based on application requirements.
Low pressure drop: cold plates exhibit minimal pressure drop, ensuring efficient fluid flow without excessive pumping power.
Stamped and brazed cold plates
Stamped and brazed cold plates are made by stamping thin, metal sheets, one flat sheet and another sheet with formed channels, and then brazing them together. This process creates a sealed channel network for the cooling fluid.
