Material description of main components of plate heat exchanger
From the development history of plate heat exchangers, we can easily see that the ultimate goal of each improvement is to improve the heat exchange efficiency between the media. In the early stage of the development of the plate heat exchanger, due to the limitation of the technical level, the development of the plate heat exchanger is mainly the structure and plate shape, which is calculated and analyzed through thermal experiments. After entering the modern era, the development of plate heat exchangers focuses on the selection of component materials and the optimization of structural details.
