Fig. 1 - Heat pipe shell made from microgrooved sheet

Main application of DC capillary structures is constructional wicks of heat pipes

    Base advantages of DC capillary structures

  • The constancy of structure parameters
  • High permeability
  • Large capillary pressure
Parameters of capillary sheets
Material all metall and plastics produced as sheets
Width of capillary gap, micron from 5
Height of capillary gap, mm 0,06 - 1,0
Thickness of capillary sheet, mm 0,15 - 1,5
Capillary sheet dimensions up to 450* 450
