Stainless Steel Liquid Cold Plate

Stainless Steel Liquid Cold Plate

Do you think the cooling performance of stainless steel liquid cold plates is not good enough?
In fact, a liquid cold plate can cool plates better than an air-cooled heatsink; it's about 5 times more effective in cooling performance than an air-cooled heatsink. Also, stainless steel liquid cold plates don't require the coolant management.

Want to know the reason why the brazed Liquid Cold Plates can:

  • Reduce more temperature
  • Achieve uniform cooling

Feature

  • High corrosion resistance
  • Easy management of coolant
  • Uniform cooling

Managing the coolant is not necessary thanks to the high corrosion-resistance of stainless steel.
For example, if you use liquid cold plates made of other materials, you would have to install an ion exchange unit in the circulation path to manage the coolant. But a stainless steel liquid cold plate doesn't require such a device.

Please feel free to contact us for chillers, piping, Teflon tubes, grease, and thermal conduction sheets.

Coolant

The product's material can determine what type of coolants to use in the liquid cold plate.
We will suggest the optimum combination of the plate's material and coolant according to your requests and operating environment.

Copper
  • Pure water (managed by ion exchange unit)
  • Industrial water, tap water (neutral, requires management of pH)
  • Antifreeze (with rust inhibitor)
    Ethylene glycol + pure water
    Propylene glycol + pure water
Aluminum
  • Pure water (managed by ion exchange unit)
  • Antifreeze (with rust inhibitor)
    Ethylene glycol + pure water
    Propylene glycol + pure water
Stainless
  • All kinds of coolants are available.
    * Pure water, Industrial water, City water and Antifreeze
