Loop Heat Pipes

LHP for thermal control

A Loop Heat Pipe is a highly effective two-phase heat transfer passive device. They are flexible because evaporator and condenser are independent, have high heat transport capability, allow mechanical decoupling and operate under adverse orientation in ground. IberEspacio manufactures Loop Heat Pipes with the following characteristics:

  • Size and shape: according to client requirements
  • Evaporators: from 40 mm to 400 mm length
  • Material of capillary pumps: nickel, stainless steel and titanium
  • Working fluids: ammonia, propylene, ethane and Freon R134a
  • Projects: Intelsat 19, Intelsat 20, Star One C4, Astro-H and 16 missions more
