Device to Application Fit
Heat Pipe: High heat flux, small footprint.
Vapor Chamber: Isothermal surface, even distribution.
Thermosiphons: Gravity-assisted, vertical orientation.
Loop Thermosiphons: Remote heat removal, flexible piping.
Wick Selection
Grooved Wick: High heat flux, low cost, orientation dependent.
Sintered Wick: High capillary limit, supports gravity-defying orientations.
Mesh Wick: Design flexibility, high permeability, lower cost.
Working Fluid Comparison
Water: 5°C to 150°C, high efficiency.
Ammonia: -60°C to 60°C, aerospace.
Methanol: -40°C to 120°C, moderate performance.
Acetone: -40°C to 120°C, fast response time.
Orientation Sensitivity
Horizontal: Maintains stability across wide gravity.
Against Gravity: High reliability, requires sintered wicks.
With Gravity: High reliability, gravity-assisted.
Loop Thermosiphons: Naturally separates vapor/liquid phases.
Typical Implementation
Heat Pipe Assembly: Air-cooled fins and fan.
Heat Spreaders: High density heat dissipation.
