Cutting Technology


Subsurface channels

Designed for cooling elements of electronic equipment, as well as biological and medical coolers. Cooling is based on pumping of liquid or gaseous coolants through channels within the plate.

Subsurface channels manufacturing bases on:

  • creating a seamless subsurface channels in cylindrical or flat workpieces
  • bonding two finned plates by brazing (soldering), diffusion welding or gluing.
