 Heat pipe Solar collector

Heat pipe Solar collector



   The structure of the vacuum tube for a heat pipe collector is very similar to the fluid type collector. In a heat pipe vacuum collector, the solar fluid does not absorb the energy directly. Instead, there is a refrigerant in the tubes that indirectly heats the solar fluid.

  

   The graphics below shows how a Heat Pipe type collector inner structure and how it works.

 

 

 

1、The solar fluid is circulated up around the panel from left to right.

2、The solar energy is collected by the Vacuum Tube. This traps the energy inside like a thermos flask.

3、The inner tube with it's selective coating gets hot. An aluminum fin is in contact with the inner glass surface. Heat is conducted from the glass into the aluminium. The aluminium fin surrounds the copper heat pipe. Heat is conducted from the fin into the copper heat pipe.

4、Inside the copper pipe there is a refrigerant which evaporates. When it evaporates, it rises to the top of the pipe by convection. It comes into contact with a copper bulb which transfers the heat into the solar fluid which circulates in the header. The refrigerant cools, condenses and flows by gravity back down the heat pipe until it is heated again.

5、The solar fluid, having been heated by 20+ tubes, leaves the collector and is circulated to the external system. The process begins again at step #1.

   Heat Pipe type vacuum collectors are convenient and very easy to transport. Handling is easy as the tubes can be disconnected from the manifold of the collector and fitted after installation.
   Heat pipes must be installed at a minimum angle of 15°to the horizontal to ensure that the recirculation of the refrigerant within the heat pipes can occur.
