Stainless Steel Cold Plates
What are Stainless Steel Cold Plates?
Stainless steel cold plates are advanced thermal management solutions designed to provide efficient cooling for various components and systems. These cold plates are manufactured using stainless steel, a material known for its excellent corrosion resistance, strength, and durability.
Stainless steel cold plates are engineered to transfer heat from the source to a coolant, which can be liquid or air, ensuring optimal temperature regulation and reliable operation of components. They are widely used in industries with strict hygiene requirements or demanding environments, such as the food and beverage, medical and pharmaceutical, and electronics industries.
Product examples
Round Stainless Cold Plate
After Tig welding with a water-cooled lid to the main body, distortion correction and machine finishing are performed. After that, the distortion correction is done again to get flatness.

Square Stainless Cold Plate
After Tig welding with a water-cooled lid on the main body, the distortion correction is performed to get flatness. Material SUS304、SUS316 Size W200mm～400mm x L500mm～1500mm Industry Vacuum Industry Processing details Machining Center, Tig Welding
Process❶ Pre-weld processing
Cut water cooling groove and water cooled lid fitting stage in plate body (t10x200x400), t=1.5.
Process❷ Welding
Knock the lid into the processed fitting step.
Process❸ Tig weld lid to body all around.
Check the bowl-shaped bend on the surface plate.
Process❹ Reduce distortion
Using a specialized press, repeatedly press the points on the surface that will be in contact with the heat source to correct the bends.
Process❺ Check the levelness
Check the flatness within 0.2 using a scimitar on the surface plate.
Comparing Stainless Steel Cold Plates with Other Materials
Stainless steel cold plates are often compared to other materials, such as aluminum and copper, 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.
Copper Cold Plates
Copper cold plates offer superior thermal conductivity compared to aluminum cold plates, making them ideal for high-performance cooling applications. However, copper cold plates are typically heavier and more expensive than their aluminum counterparts.
Applications of Stainless steel Cold Plates
Stainless steel cold plates are used in a wide range of applications across various industries, such as:
Electronics and Semiconductor Cooling
Stainless steel cold plates are also used in the electronics and semiconductor industries for cooling power electronics, laser systems, and other heat-sensitive components. While not as thermally conductive as copper or aluminum cold plates, stainless steel cold plates can still provide adequate cooling performance in applications where corrosion resistance and compatibility with various coolants are more important considerations.
Food and Beverage Industry
Stainless steel cold plates are widely used in the food and beverage industry for cooling processes, equipment, and storage systems. Their excellent corrosion resistance and compatibility with various coolants make them ideal for maintaining strict hygiene standards and preventing contamination.
Medical and Pharmaceutical Industry
In the medical and pharmaceutical industry, stainless steel cold plates are employed for cooling critical components and equipment , such as imaging systems, laboratory instruments, and temperature-sensitive pharmaceutical products. Their corrosion resistance and ability to withstand harsh cleaning and sterilization processes make them an ideal choice for these demanding applications.
