Description

technical field [0001] The invention relates to a steam condensation heat exchange test device, which belongs to the field of heat exchangers. Background technique [0002] With the increasing attention and promotion of energy-saving technology, the utilization of heat energy in steam condensation has been mainly studied as a main energy-saving direction. There have been some studies on steam condensation. As an energy-saving and high-efficiency component, heat exchange tubes have been widely used in various heat exchange fields. The development and utilization of heat exchange tubes has reached a very mature stage, such as air coolers, water coolers, heat pipes and other heat exchangers have been widely used. However, the research on condensation heat transfer in the prior art mainly focuses on the two methods of horizontal condensation heat transfer tube and vertical falling film condensation heat transfer tube. Both horizontal and falling film heat transfer tubes must u...

Problems solved by technology

However, the research on condensation heat transfer in the prior art mainly focuses on the horizontal condensation heat exchange tube and the vertical falling film condensation heat exchange tube. The horizontal and falling film heat exchange tubes must use metal to achieve rotation The metal hose is used to connect the heat exchange device, but the metal hose will be cross-wound due to rotation, so free rotation and loads of different frequencies cannot be achieved

So far, no one has installed the condensing heat exchange tube on a platform that can easily realize different rotation loads and at the same time research the heat transfer performance of the heat exchange tube
