·Operation principle: Direct flow vacuum tube is
designed according to specialty of heat pipe, vacuum tube and
craftwork criterion used in Europe. The heat absorbing part of
direct flow vacuum tube is transferred to the cooling part.
With reasonable circulation path design, the medium can be
operated in a smooth and efficient way. ·Product specialty: ●
High heat collecting effectiveness without problem of
performance recession; ● Able to endure high pressure, the
highest degree of which is 12kgf/cm2; ● Able to be deployed
neatly-realize once heat exchange and twice heat exchange in
enveloped state.
