Component Specifications

Definition
A cooling passage is an engineered component integrated into industrial machinery, such as platforms, to manage thermal loads. It consists of internal channels or conduits through which a coolant (e.g., water, oil, or air) flows, absorbing heat from critical areas like motors, bearings, or electronic controls. This system prevents overheating, reduces thermal stress, and enhances equipment longevity and efficiency by maintaining temperatures within specified operational ranges.
Working Principle
The cooling passage operates on the principle of forced convection and heat exchange. Coolant is pumped through the passage, absorbing thermal energy from hot surfaces via conduction. The heated coolant then exits, dissipating heat through a radiator or heat exchanger, and is recirculated. This continuous cycle stabilizes temperatures, with flow rate and coolant properties tailored to the thermal load.
Materials
Typically made from corrosion-resistant materials such as stainless steel (e.g., AISI 304/316), aluminum alloys (e.g., 6061-T6), or copper alloys. For high-pressure applications, materials must meet strength requirements per ASTM or ISO standards.
Technical Parameters
  • Flow Rate 10-500 L/min
  • Surface Finish Ra ≤ 3.2 μm
  • Pressure Rating 1-10 bar
  • Channel Diameter 5-50 mm
  • Temperature Range -20°C to 150°C
Standards
ISO 1217, DIN 2448
