Solar engineering junction box is also called solar engineering junction box and solar engineering heat collection box. An important part of the solar water heater project, it is used to collect and store solar heat. Modular installation. Originating from China and developing rapidly in the Chinese market, it is widely used in solar water heating projects. In the past two years, it has been accepted by more and more solar water heating projects in more than 95% of project managers. in the world are manufactured in the Chinese market. According to the hot and cold water circulation principle of solar engineering heat collection module, it is the theoretical basis for the design of solar engineering collector. According to the role of solar engineering collector in solar engineering, it is hot and cold water. exchange container. This is an import taskante to improve the heat exchange efficiency of the solar engineering collector. Firstly, reduce the collector capacity of the solar project so that the cold water can gain high-frequency potential energy and accelerate the frequency of hot and cold water exchange. The second is to improve the thermal insulation effect of solar engineering collectors and reduce heat loss. The design requirements of the water inlet and outlet of the third solar project collector are to overcome the air blocking phenomenon, improve the hot and cold water exchange speed of the solar project collector in series and increase the stability of water movement. According to this guiding ideology, we design, organize processes and organize the production of solar engineering collectors.
The function of the manifold is to connect different sections to ensure smooth flow of fluidof work. Used to collect and store solar heat. Metal heat pipe solar project head; indirect heat exchange, low thermal efficiency and the explosion tube does not leak during solar project operation. Metal heat pipe is used for a long time to reduce vacuum degree, reduce heat transfer efficiency, high workmanship. cost and high maintenance cost.
The manifold is made of seamless steel pipes with flat heads welded on both ends. There are several pipe heads on the manifold which are welded and connected to the pipes. The header is divided into top header and bottom header. It is placed outside the oven like a collector and is not exposed to heat.
The bottom of the water-cooled lower wall collector is also equipped with a regular sewage discharge device and a steam heating device. The material of the collarector is usually carbon steel or low alloy steel, such as 20 steel, 12CrlMoV, etc.
Detailed information
The boiler header of the power plant is composed of a pot which contains water to generate steam and d 'an oven that burns to generate heat. of the combustion is transferred to the boiler. The water in the boiler must have sufficient heat transfer surface area. In order to expand the heat transfer area, barrel boilers are transformed into tube boilers to increase the heat transfer area.
Water in these tube bundles must circulate continuously to absorb thermal energy and separate steam. The steam above collects in the top of the box (cylinder) and the water at the bottom flows into the box. (cylinder) below and is distributed to each tube. The tube will continue to absorb heat from the oven.
The wallof a utility boiler is made up of rows of pipes. But it is not possible to use all the tubes. The boiler is huge and complex in structure, and it is impossible to drain the fluid through all the tubes.
Install a collector at a certain position, so that the water from each pipe can be merged here and then distributed to each pipe at the next level. This can reduce thermal deviation and facilitate work heat absorption. more efficient fluid. Flow rate, boiler cooling and boiler thermal efficiency are all optimized.
