(2) working principle:
Working principle is as shown in figure 5. Under the sunlight irradiation, the coating of tube evaporation section absorb heat, the temperature of inside tube rise gradually, wick medium is heated to vaporize, and come to being vapor pressure, in the affect of the steam pressure, steam at the speed of sound from the evaporator to condenser section, it releases the latent heat of phase change when it is cool, and condensed into liquid water beads, and along the inner wall to return to the evaporation, go round and begin again, heat transfer and exchange through the phase transition. In the one-way superconducting heat transfer mode, absorption heat of evaporation section irreversibly transfers to the condensation section.
All glass double vacuum type solar collecting tubes is working, every tube can convert the solar radiant energy into the heat energy, by vapor - liquid phase change cycle repeatedly of the tube the heat will through the condenser section to transfer to the heat conduction block (or thermal casing), and to heat the system cycle working medium of the coupling device , so the system cycle working medium temperature is gradually increased, until meeting the use requirements.At the same time, the vacuum tube and heat preservation box also inevitably loss heat in the form of radiation or conduction.
It is worth mentioning that the connection between the vacuum solar heat collecting with the coupling device is belong to "dry connection" , it means that it is no direct contact between the working medium of the coupling device and the condenser section of the heat collecting tube, the collector has no leakage hidden trouble, can run under high pressure.the damage of the individual tube will not affect the operation of the entire collector, and it is very convenient to be maintained. Therefore, it is especially suitable for large and medium-sized solar hot water system, and it is easy to implement the combination with architecture.
