High Temperature Thermal Devices for Nuclear Process Heat Transfer Applications

Abstract

1.1 Heat exchangers A heat exchanger is a component used to transfer heat from one medium to another. The media may be separated by a solid wall, so they never mix, or they may be in direct contact (Kakac and Liu 2002). Heat exchangers generally have no external heat nor work interactions and are typically used in the following applications: • Space heating • Refrigeration • Air conditioning • Power plants • Chemical plants • Petrochemical plants • Petroleum refineries • Natural gas processing.
