For absorber absorbed and transformed into heat energy, and to working medium in the fluid channel. In this way,
From the bottom of the collector inlet cold working medium, is heated by solar energy in the fluid channel, temperature one by one
Gradually rise, heated hot working medium, with useful heat energy from the top of the collector export, storage
Into the water storage tank for use, is the useful energy gain. At the same time, due to the endothermic body temperature rises
High, dissipating heat to the environment through the transparent cover plate and shell, constitute the flat plate solar collectors
Heat loss.
1.1.2 endothermic board
Endothermic board is flat solar collector to absorb solar radiation and heat transfer within the working medium
Heat transfer components, which is basically a flat shape.
The structure of 1.1.2.1 endothermic board
On the flat shape of endothermic board, usually decorate a row tube and manifold. Exhaust pipe is refers to the suction
Hot plate parts vertically and fluid channel; Header is refers to the heat absorbing plate at both ends up and down horizontally
Connecting several row tube and a fluid channel parts. Endothermic board has a variety of materials, there is
Copper, aluminum alloy, copper aluminum composite, stainless steel, galvanized steel, plastic, rubber, etc. Endothermic board has
The following main structure form.
(1) tube plate. Tube-sheet heat absorbing plate is a combination of exhaust pipe and plate at a certain way
Pick up a heat absorption bands, and then to set up and down tube welding into a collector. This is at home and abroad
Using common type of endothermic board structure.
Solar energy research institute in wuhan city in 1986, one has the international advanced imported from Canada
