Pressurized solar collector
--------------------------------------------------------------------
The JINYI pressurized solar collector offer excellent value as they have a very low cost per kWh of output.
The pressurized solar collectors are also very easy to transport and handle as the tubes can be disconnected from the manifold of the collector.
The JHC collectors are heat pipe type collectors in which the tubes transfer the collected energy to the manifold, where it heats the solar fluid.
They are ideal for different latitudes due to their high efficiency, especially advanced in high latitude area, even in cold winter.
These models incorporate 12,15,18,20,24,25,30 evacuated tubes.
Benefits:
1. Collects free solar energy and reduces dependence on expensive fossil fuels
2. Good for the environment; reduces emissions of CO2 and other pollutants
3. Excellent value
4. Heat Pipe technology means collector can be easily transported and then assembled on-roof
5. Can be installed on-roof initially and have the tubes added later during commissioning

The Principle of Thermosyphon:
Metal pressurized solar collector consists of a evacuated tube, a heat pipe, a metal heat absorption wing and the connecting manifold. The metal heat absorption wing with selective absorption coating converts solar energy into heat energy and transfers it medium liquid inside. The vacuum between the two glass tubes works as insulation. The liquid in the heat pipe changes into vapor which rises to the condenser. When passing through the heat exchanger, the heat is absorbed and the temperature is lowed, and the vapor becomes liquid, returns to the base of the heat pipe. This transference of heat is a continuous circulation as long as the collector is heated by the sun
