Heat Shields “Louver Design”

Rectangular Heatshield

Rectangular Heatshield

Circular Heatshields

Circular Heatshields

Heat shields come in circular and rectangular shapes and are used to protect vacuum system components (such as cryopumps) from radiated heat. Instead of the 5-bounce chevron design, these baffles have louvers which only block the line-of-site from the heat source. This allows greater conductance as compared to contamination trapping baffles.

Features:

  • Custom designed
  • Compact
  • High conductance
  • Uses any coolant (chilled water, LN2, or refrigerants)
  • May be used with cryogenic liquids
  • Increases pumping capacity
