Heat Pipe Solar Collector

Basic principle:
Vacuum tube absorb solar energy and transfer to heat pipe via aluminum fin, heat pipe is heated and working liquidvaporize and rise to the top heat pipe condenser (condenser is inserted into the manifold port inside the solarcollector manifold), when the heat pipe condenser meet cold water flow inside the manifold port, the working liquidwill cool down and fluidify return to the bottom of heat pipe, so once and once aaain repeat this process, so finallvcold water(glycol) inside the manifold port will be heated.
