Stainless Steel Heat Exchanger for Deionized Water Cooling

Customer Request:

I'm looking for a stainless steel heat exchanger for deionized water cooling.

We need an 80W/C cooling capacity, 2l/min flow, and expect it to be roughly 30x30cm.

Using a stainless steel heat exchanger for deionized water cooling is a common and effective choice, especially in applications where corrosion resistance and cleanliness are crucial. Deionized water, being highly pure and free from ions, can be aggressive and potentially corrosive to certain materials. Stainless steel is chosen for heat exchangers in such applications due to its excellent corrosion resistance.

Typically, a grade of stainless steel with high corrosion resistance is chosen for heat exchangers used in deionized water cooling. Common choices include 316 stainless steel or higher grades.

Stainless steel heat exchangers are often passivated to enhance their corrosion resistance. Passivation is a chemical process that removes free iron from the surface, creating a protective oxide layer.

Stainless steel has good thermal conductivity, allowing for efficient heat transfer between the deionized water and the fluid being cooled.
