Product description
Professional Thermal Management Solution
What is a Liquid Cold Plate?
A liquid cold plate is a high-efficiency thermal management device engineered to cool electronic equipment and high-heat-load components. It features a precision-machined housing with internal channels—designed to allow coolant (such as water) to flow seamlessly—paired with a welded cover that seals the channels for leak-proof operation. How does a liquid cold plate work? Coolant circulates through the flat, metal plate’s internal channels, absorbing heat directly from the heat-generating components it contacts. As the coolant flows through the system, it efficiently transfers the absorbed heat away from the equipment, maintaining optimal operating temperatures and preventing overheating.
Most liquid cold plates are constructed from aluminum, though copper is also a common material choice. Both metals are preferred for their exceptional thermal conductivity—a critical property that ensures fast, effective heat transfer and maximizes the liquid cold plate’s cooling performance.
Liquid cold plates are essential for custom thermal management solutions in industries where precise, reliable equipment cooling is non-negotiable. Key applications include rail, wind energy, solar energy, aerospace, space, data centers, military, computing, lasers, and telecommunications equipment.
Liquid coolingPlate advantage
Compare with air, Liquids have a much higher heat capacity so can remove more heat from the heat element.
Compare with air, Liquids have a much higher thermal conductivity so can more efficiently transfer heat away from the heat element.
By using a closed-loop system, the liquid can be circulated and cooled by a chiller or other external cooling device, making it possible to maintain very low temperature.
Because there is no need for large fans. The size and weight of liquid cooling plates is often smaller than air-cooled systems
By using antifreeze ethylene glycol and water and Propylene Glycol and Water (PGW) when dealing with low temperature environments, Liquid cooling plates will avoid icing problems.
