What Is Vacuum Brazed Liquid Cold Plate?

Vacuum brazing is a manufacturing process that joins together components using a filler metal called a brazing alloy, often conduct in a furnace. Vacuum Brazed Liquid Cold Plates use this principle to realize the connection of aluminum or copper base plate, composite brazing material plate & cover plate.

Advantages of Vacuum Brazed Liquid Cold Plate:

State-Of-The-Art Technology

Vacuum brazing is a material joining technique that offers significant advantages: extremely clean, superior, flux-free braze joints of high integrity and strength.

Competitive Costs

Vacuum brazing prevents oxidation and contamination of the joint surfaces, resulting in clean, oxide-free joints that do not require any other finishing or cleaning.

Quality Control

HY thermal Tech is ISO 9001:2015-certified, IATF-registered, and RoHS-compliant manufacturer since 2006.

We have expertise and experience in Liquid cooling systems, CNC machining, and brazed joint assemblies for high-precision components more than ten years.

Materials determine coolants


The best combination of the plate's material and coolant we suggest as follow:

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)
