Product Introduction
The heat pipe solar collector always connected with existing water heating device. The selective absorber coating on the inner cover of vacuum tubes absorb solar energy, then convert solar energy into thermal energy and transfer thermal energy to heat pipe by aluminum fin. The heated liquid inside heat pipe change into vapor which rises to the top condenser, then thermal energy heat transfer liquid pass through heat exchanger and the cooled vapor becomes liquid, returning to the base of heat pipe.
The thermal energy conducts to transfer liquid via a copper pipe. This transference of heat into the liquid creates a continuous circulation as long as the collector is heated by the sun.
