Heat Pipe Collector uses highly efficient vacuum tube as the absorber, each glass tube is fitted with an aluminum contact fin which serves to be the heat transfer contact and also fixes the heat pipe against inner wall of the glass tube.  The heat pipe is evacuated and filled with minimum heat transfer liquid which is frost proof, heat will be transferred from heat pipe evaporator to condenser, then transfer to the liquid in the solar loop.

Heat pipe collector header comprises one copper main pipe, in contact with each heat pipe to transfer the heat.

The header is insulated with polyurethane foam and encased with an UV stabilized aluminum profile.

Heat pipe collector can be used either forced circulation or natural circulation system, both ways can ensure the optimum thermal performance of the whole system. HP-16 collector header structure and material are able to withstand stagnation without damage, if stagnation does happen.
