Flat plate solar collector is the flat shape of endothermic, hence the name. It accounts for a transparent lid, heat-absorbing plate, and coat the four components. Solar radiation through the transparent collector cover, projected onto the endothermic board endothermic plate absorbed and converted into heat, then heat transfer to the heat-absorbing plate heat transfer working fluid, making it temperature, as Useful energy output. Transparent cover protects the endothermic main board role, while the sun can be projected well into the transparent cover material, there are strict requirements, not only to better light transmission, and stress resistance stronger. Endothermic board has experienced many ups and downs, such as early stage, pipe and plate combined with multi-use binding, riveting, gluing and other techniques, but because these processes are very backward, produce heat transfer resistance. Later, industry experts invented the high-frequency welding, ultrasonic welding and other advanced technology, which makes them difficult to be addressed. In 1986, a Beijing Solar Energy Research Institute introduced from Canada with the international advanced level of a copper and aluminum composite solar production lines, only to make flat panel solar collector technology onto a new level. Endothermic board coated with a layer of dark, this coating can maximize the absorption of solar radiation over the energy and transformed into heat. Endothermic heat insulation layer is to hold the plate heat, try not to heat diffusion, the loss to a minimum. Flat panel solar collector Yang was invented in the late 17th century, but it was only after 1960, the real depth and scale to be applied.
