CarlIn the rapidly evolving realm of technology, the demand for efficient cooling techniques for high-power electronic components, and power electronics has increased. While air-cooled systems have been used traditionally, they have limitations. Liquid cooling systems, on the other hand, provide several benefits such as heightened cooling efficiency, lower noise, and superior thermal performance.
What is a Water Cold Plate?
A water cold plate refers to a metal plate that contains channels or tubes that circulate a liquid coolant, such as water or a water-glycol blend. Copper or aluminum, materials known for their high thermal conductivity, are typically used to construct the cold plate. It is positioned on or near the electronic components that need cooling.
The Functionality of a Water Cold Plate
Heat from the electronic component is transferred to the liquid coolant in order for a water cold plate to function. The thermal interface material (TIM), which conducts heat from the electronic component to the cold plate, helps to keep the latter cool. Heat is taken from the cold plate and transferred to a radiator or another heat exchanger by the liquid coolant that is flowing through the cold plate’s channels.
Types of Water Cold Plates
There are several varieties of water cold plates, such as single-pass, dual-pass, and multi-pass cold plates. Single-pass cold plates enable the coolant to travel through their channels just once before being sent to the radiator. They might not provide the most effective cooling, while being affordable and easy to use.
On the other hand, dual-pass cold plates enable the coolant to travel through the channels twice before being sent to the radiator. When compared to single-pass cold plates, this kind of cold plate offers higher cooling performance. Coolant can travel through the channels of multi-pass cold plates many times before being sent to the radiator. While it could be more expensive, this kind of cold plate provides the best cooling performance.
Water Cold Plates’ Benefits
Compared to traditional air-cooled systems, water cold plates provide numerous advantages, including better cooling effectiveness, less noise, increased thermal performance, and environmental friendliness. The increased cooling efficiency of water cold plates stems from the fact that water possesses a greater thermal conductivity than air.
Inferring that water can transmit heat more effectively than air, cold plates made of water are better able to cool electronic components than those made of air-cooled systems.
Because water cooling systems don’t need fans to cool the electrical components, they are often quieter than air-cooled systems. Compared to air-cooled systems, water cold plates may maintain a temperature that is more constant, enhancing the functionality and dependability of the electronic components. Water is a safe cooling agent that can be recycled or reused and contains no toxic ingredients. Due to this, water cooling systems are environmentally responsible and long-lasting alternative to conventional air-cooled systems.
Applications
Several industries, such as high-performance computers, the automobile, aerospace, and medical equipment, employ water cold plates.
High-power CPUs, GPUs, and memory modules in data centers and supercomputers are cooled using water cold plates in high-performance computing. Water cold plates are used in the automobile industry to cool the electric motors, batteries, and power electronics in electric and hybrid vehicles.
Aircraft and spacecraft avionics and other electronics can be cooled using water-cooled plates in aerospace applications. Water cold plates are used in the medical sector to cool MRI scanners, laser systems, and other medical apparatus.
