The new U-type solar heat pipe is composed of one lesser copper
pipe and another bigger copper pipe. And the pipeline of new U-type
is composed of two transverse parallel water pipes and several
vertical parallel equidistant new U-type pipes. The new U-type
solar collector is composed of pipeline, insulation, vacuum tubes
and frame. Heat Collecting Principle: The vacuum tubes absorb the
solar energy to be heat energy, then heat energy is transferred
from aluminium sheet to the outer copper pipe. The cold water flows
from inlet to outlet through inner copper pipe to the outer copper
pipe. So that the heat energy is transferred from solar collector
to the water tank.
