[0002] Heat exchangers (also called heat exchangers or heat exchange equipment) are devices used to transfer heat from hot fluid to cold fluid to meet specified process requirements. They are an industrial application of convective heat transfer and heat conduction. Heat exchangers can be classified in different ways. According to their operating process, they can be divided into three categories: partition type, hybrid type, and heat storage type (or heat recovery type); according to the compactness of their surface, they can be divided into compact type and non-compact type.
