The application of brazed plate heat exchangers in the refrigeration industry is very common. The brazed plate heat exchanger is an efficient and compact heat exchange equipment. In the 1880s, it was successfully developed as a continuous low-temperature sterilizer, and it began to be used in the food industry in the 1920s. Due to the uniqueness of the brazed plate heat exchanger in manufacturing and use, it is widely used in petroleum, chemical, light industry, electric power, metallurgy, machinery, energy and other industrial fields, thus becoming a very competitive variety in the heat exchanger family. In addition, brazed plate heat exchangers are also used in the refrigeration field. Let’s talk about its application and development below.
