The core product of the 200-liter flat-panel solar water heater JDSOLAR is mainly used by home users and real estate. It is currently the most popular in Europe and America.
There are two types of integrated and split type, which can be operated under pressure or non-pressure.
The flat-panel solar water heater is designed and developed for small high-rise residential buildings. The water tank is placed on the balcony, roof, walls and other places. The flat solar collectors are placed on the balcony, windows, roof and walls of the building bar to make up for the regret that the traditional solar water heaters cannot be perfectly integrated with the building and the environment due to the inherent lack of energy. The collector and the water tank are separated from each other, and the collector can be flexibly installed on the roof, the skylight, the balcony or the wall, and is not limited by the position, thereby achieving the perfect integration with the high-rise building and the environment.China Produces Flat Solar Water Heater Factory
According to the different ways of water circulation, it can be divided into three types: natural circulation, forced circulation and constant temperature discharge.
According to the different way of collecting the flat collector, it can be divided into: concentrating type and non-concentrating type.
According to the market of flat-panel solar water heaters: two types of household market and engineering market.
According to the material of the flat plate solar collector heat absorbing plate, it can be divided into ceramic solar plate, copper-aluminum composite heat absorbing plate, all copper heat absorbing plate, stainless steel heat absorbing plate.
According to the structure of the flat plate solar collector heat absorbing plate, it can be divided into tube plate type, wing tube type, coil type, flat box type, round tube type and heat pipe type.
The flat-panel solar water heater is composed of a heat absorbing plate, a cover plate, an insulation layer, and an outer casing.
Heat absorbing plateChina Produces Flat Solar Water Heater Factory

(1) role
Also known as an endothermic core, it is a component that absorbs solar radiation energy and transfers heat to the water.
(2) Technical requirements
1 Technical requirements are a certain pressure bearing capacity, good compatibility with water, excellent thermal performance, simple processing technology and reasonable cost. Commonly used materials are copper, aluminum alloy, stainless steel, galvanized sheet, coastal water quality, and plastic or fiberglass.
2 Selective coating: In order to increase the thermal performance of the heat absorbing plate, the coating is often sprayed on the metal surface. The coating is divided into a selective coating and a non-selective coating.
3 flat plate collectors are classified into two types according to the type of coating: black film and blue film (black chrome, anodized)
(3) Heat absorber
Also known as the heat absorbing body, the heat absorbing body is the core component of the flat solar water heater, which first completes the light and heat conversion, and then transfers the heat energy to the water to be heated.China Produces Flat Solar Water Heater Factory

The heat absorbing body is mainly made of a metal material, and the initial structure is a steel pipe tying structure. Later, a welded type, an aluminum wing type, a copper-aluminum composite type has appeared, each having its own merits. Some combine thermal conductivity difference, some have too high energy consumption, some have too many consumables, and some have complicated processes. But in common, heat transfer is several tens to hundreds of times higher than glass. For example, the thermal conductivity of copper is around 320, aluminum is around 160, copper is around 40, and glass is only 0.64. The pressure resistance can reach 10KG/CM2, and the glass can not withstand the pressure of 0.5KG/CM2.
Therefore, the metal heat absorber can perform natural circulation, forced circulation and direct current operation. Since the flow rate is proportional to the heat transfer coefficient, the heat absorption efficiency of the metal heat absorber is also much higher.
The tube plate of the heat absorbing body combines the new technology, only one punching machine is needed, and the two sets of dies can be mass-produced. It can be said that the equipment is small and the investment is saved; only the three processes of punching, wearing and pressing can be completed, which is simple and easy to carry out; No need for welding or other auxiliary materials, it can save energy and work; thin-walled copper tube is used as the tube, and thin aluminum plate is used for the fin. It is a scientific combination with good corrosion resistance, good heat transfer and material saving.China Produces Flat Solar Water Heater Factory
