The solar engineering header is also called the solar engineering joint box. An important component of solar water heating projects is used to collect and store solar heat. Modular installation. It originated in China and has developed rapidly in the Chinese market. It has been widely used in solar water heating projects. It has been accepted by more and more national solar water heating projects in the past two years. More than 95% of the world's engineering bins are Produced in the Chinese market.


The junction box solar water heating system is a combination of a tubular collector collector array, a hot water storage tank, an auxiliary heating system, an intelligent control system, a pipeline and a circulation system. The outlet water temperature and energy can be set as needed. A semi-thermal solar water heating system that works with conventional energy sources to achieve 24-hour continuous hot water supply.

The vacuum collecting tube receives solar radiation and converts the collected solar radiant energy into internal energy, that is, the vacuum tube obtains kinetic energy and thermal energy, the water temperature is the internal energy size image, and the solar energy engineering box has two ways of vertical or horizontal, and the cold water is in High-end gains potential. The hot water in the vacuum tube rises under the action of kinetic energy, and the cold water in the header decreases under the action of potential energy. This is the principle of solar natural circulation. Under the guidance of this principle, the heat transfer efficiency of the solar engineering header box horizontal tube or vertical row is independent of the installation method, and the relationship between not less than a certain cross-sectional area and the vacuum tube interface is independent of the heat transfer efficiency. When the water temperature in the collector reaches the set temperature, the hot water in the collector is sent to the hot water storage tank with the heat preservation function through the temperature sensor, the temperature controller, the electromagnetic valve, the water pump and the like, and is stored. At the same time, it automatically fills in cold water. After the water level reaches the upper limit of the hot water storage tank, the temperature controller starts the corresponding equipment, automatically switches the system operation mode into the temperature difference cycle, forms a circulation between the collector and the water tank, continues to use the solar radiation energy, and further increases the water temperature of the water tank. . After years of research, Jiayou Sunshine Solar explained the principle of natural circulation of solar hot and cold water. It can establish a mathematical model to reflect the natural circulation of solar hot and cold water, and guide the design and development of solar thermal products. For example, the Jiayou Sunshine Solar Explosion Pipe Watertight Project Ledger is completed under the guidance of this principle.
