                                                        Heating principle                                                    

     Evacuated Tube Collectors combine the high efficiency performance of evacuated tubes with rapid heat

transfer capacity of heat pipes to provide a collector that can operate efficiently in almost any climate providing

hot water for residential or commercial solar water heating projects.

3.Advantage About vacuum solar collector                                                                 

       Vacuum tube solar energy work principle is the use of heat absorbing coating on the inner tube of the solar light absorption and heat inside the tube in the water in the water tank or even box to improve the water temperature.

      As a set of hot plate, it is also carried out in the heat of the heat transfer in the same time, only three ways of radiation conduction convection. Vacuum tube solar energy heat transfer three kinds of heat transfer is very small tube of the mercury coating to prevent heat radiation and heat conduction in the middle of the vacuum layer to prevent heat conduction as the heat of the convection heat transfer to the vacuum tube solar energy is almost zero.

     The thermal efficiency of 93.5% is higher than that of flat panel solar energy increased by 50-80%.
