Cooper Cold Plates
What Are Cooper Cold Plates?
Copper cold plates are advanced thermal management devices specifically engineered for efficient cooling of components and systems. They are designed to dissipate heat generated by high-power electronic devices, machinery, and other heat-sensitive equipment.
These cold plates are made of copper, a metal known for its outstanding thermal conductivity and heat transfer properties. By utilizing copper, cold plates can effectively transfer heat from the source to a coolant, such as liquid or air, ensuring optimal temperature regulation and reliable operation of components. Copper cold plates are commonly found in industries such as electronics, high-performance computing, renewable energy, aerospace, and defense.
Product example
Copper Cold Plate
Pure copper is a difficult material, and warping occurs after cutting or joining. Therefore, in order to ensure the thickness of the water-cooled lid, distortion correction is necessary each time.It is also easy to scratch, so you need to pay close attention Material Pure Copper C1020 Size W300mm～400mm x L1000mm～1500mm Industry Vacuum Industry Processing details ...
Process❶ Before welding (Preparation)
- On the main plate, the groove where the cooling water flows and the fitting part of the same depth as the thickness of the lid are machined.
- Cover the joint groove with a lid (tapping so that there is no step on the bonding surface)
Process❷ FSW processing
At the time of joining, metal scrap is discharged around the joint by pressing force (1.2t) from the top of the tool and the force moving sideways. As shown in the image below, the joint marks by the tool remain (slightly discoloration due to frictional heat)
Process❸ After Finishing
1mm cutting from joined end face
The boundary of the joint cannot be determined as shown in the image below, and it can be understood that the main plate and the lid are integrated.
Applications of Copper Cold Plates
Copper cold plates are widely used across various industries and applications
Electronics and Semiconductor Cooling
Copper cold plates play a critical role in dissipating heat from high-power electronic devices, integrated circuits, and semiconductors. By efficiently transferring heat away from these components, copper cold plates help maintain optimal operating temperatures and prevent thermal-related failures.
High-Performance Computing Systems
In data centers and other high-performance computing environments, copper cold plates are used to cool processors, graphics processing units (GPUs), and other heat-generating components. By ensuring effective cooling, copper cold plates contribute to the stability, performance, and energy efficiency of these systems.
Renewable Energy Systems
Copper cold plates are utilized in cooling systems for solar power inverters, fuel cells, and other renewable energy applications. These systems often generate considerable heat during operation, and efficient cooling is essential for maintaining performance, reliability, and service life. Copper cold plates provide the necessary thermal conductivity to dissipate heat effectively, ensuring optimal functioning of these renewable energy systems.
Aerospace and Defense
In aerospace and defense applications, copper cold plates are employed for cooling mission-critical systems, avionics, and other heat-sensitive components. With their excellent thermal performance and corrosion resistance, copper cold plates ensure the reliable operation of these systems, even in harsh and demanding environments.
Industrial Equipment Cooling
Copper cold plates are also used in various industrial applications, such as cooling hydraulic systems, power electronics, and high-power laser systems. By providing efficient heat dissipation, copper cold plates help maintain the performance and extend the life of these essential industrial systems.
Comparing Copper Cold Plates with Other Materials
Copper cold plates are often compared to other materials, such as aluminum and stainless steel, each with its unique set of advantages and disadvantages.
Aluminum Cold Plates
This case is a prototype development Aluminum cold plates are lighter and more affordable than copper cold plates but typically have lower thermal conductivity. This makes them suitable for applications where weight and cost are more important than maximum heat transfer performance. However, in high-performance cooling systems, the superior thermal conductivity of copper is often preferred.
Stainless Steel Cold Plates
Stainless steel cold plates provide excellent corrosion resistance but have lower thermal conductivity compared to aluminum cold plates. While stainless steel is suitable for applications that require exceptional resistance to corrosion and chemical attack, it may not be the best choice for applications where high heat transfer performance is crucial.
