In general, the sun shines through the transparent cover to the surface of the absorber coated with an absorption layer on the absorber, most of which solar radiation can be absorbed by the absorber, converted into heat energy, and transmitted to the working medium in the fluid channel. In this way, the cold medium entering from the bottom of the collector is heated by solar energy in the fluid channel, the temperature gradually increases, the density of the hot medium after heating will become smaller, generate upward power under the action of gravity, with useful thermal energy from the upper end of the collector outlet, through natural circulation or forced circulation to transfer the heat to the water to improve the water temperature.
