Tube type heat exchanger, also known as high-efficiency jacket heat exchanger, is mainly used to cool media such as air. Due to its efficient heat transfer performance and reliability, it has been widely used in industries such as marine diesel engines, electric power, railway locomotives, and compressors since its introduction to China in the 1980s. Under the same volume conditions, the heat transfer performance of tube and tube heat exchangers is more than 30% higher than that of shell and tube heat exchangers.
