Learn how the heat pipe heat exchanger experimental bench works
In order to fix the heat exchange tubes, a fixing frame is installed around the heat exchanger. According to the distribution position, the frame can be divided into upper and lower cover plates and side plates on both sides. In some specific places, in order to facilitate the overall fixation, an additional plate needs to be added on both sides; because of the need for effective heat exchange, we usually use seamless steel tubes with an outer diameter of 18 because the outer diameter is small and the internal space is small. Fast heat transfer speed and high heat transfer efficiency.
The fins are 0.2 ~ 0.3mm thick carbon steel fins or galvanized fins, which are distributed on the surface of the mother tube by mechanical winding, and then fixed by welding to prevent the fins from loosening and falling off. To ensure the fluidity of the heat exchange tube, replace The heat pipe and the heat exchange pipe are connected by a 180-degree elbow. The material selection of the elbow is the same as that of the mother pipe, and the welding is convenient. When welding, the continuity and smoothness of the elbow and the connecting pipe should be guaranteed to make the internal flow performance better;
The heat exchanger interface is mainly customized according to the needs of the site. For example, if the customer needs to use the flange on site, then when leaving the factory, we will use the national standard flange interface for the customer to install later. It can speed up the efficiency; as the working medium mother tube of the heat exchanger, the mother tube must meet the requirements of the overall design, otherwise the overall heat transfer performance will not meet the requirements and need to be measured by the system design software.
For gas pipelines, if customers provide drawings and requirements, we can customize them according to customer requirements to ensure that the gas pipeline requirements and design requirements are replaced on site. If customers provide drawings and requirements, we can customize according to customer requirements to ensure on-site replacement. Requirements and design requirements.
