Overview
ABSTRACT
Main industrial technologies to manufacture heat exchanger are described. Various criteria of classification are presented: by technology, by process or heat transfer mode, by application, by wall material. A table gives the main types of heat exchangers according to these criteria. The most used kinds of heat exchangers are detailed (Shell and tube, Plate, etc.) by specifying the applications for which they are the best suited.

INTRODUCTION
In industrial companies, the heat exchanger is an essential element of any energy management policy. A large proportion (90%) of the thermal energy used in industrial processes passes through a heat exchanger at least once, both in the processes themselves and in the systems used to recover thermal energy from these processes. They are mainly used in industry (chemicals, petrochemicals, iron and steel, food processing, power generation, etc.), transport (automotive, aeronautics, marine), but also in the residential and tertiary sectors (heating, air conditioning, etc.). The choice of a heat exchanger for a given application depends on many parameters: temperature and pressure range of the fluids, physical properties and aggressiveness of these fluids, maintenance and space requirements. It goes without saying that the right heat exchanger, properly sized, designed and used, will improve efficiency and reduce energy consumption.
