Technical progress and application of new high efficiency cooler
Introduction Due to the limitation of manufacturing process and technical level, the early cooler can only use simple structure, small heat transfer area, large volume, heavy, such as snake tube cooler. However, with the development of manufacturing technology, shell and tube coolers have gradually appeared. The unit volume of this cooler has a large heat transfer area and good heat transfer effect. It has become a typical cooler in industrial production for a long time. In the 1920 s, plate coolers appeared again. Coolers made of plate tube have compact structure and good heat transfer effect. There are many kinds of traditional coolers, and there is no unified division method. At present, the main
