Heat pipe vacuum tube Product Description:
3- target tubes consist of 3 metals : Aluminum, stainless steel and copper, also AL-SS-CO; it loses heat very little because emissivity of copper ion is lower than aluminum ion by 20%, so the tubes can still work well on -40°C, what’s more, stainless steel ion in the tube can resist high temperature and empty basking, so it also can work well on temperature 400°C. Absorption of 3-target tubes is higher than common tubes by 12%, but it’s emissivity is 30%-40% lower than common one.
