Heat exchange equipment - devices (or heat exchangers) are designed to transfer heat from one medium to another medium. They have received a huge distribution in many industries. There are many types of heat exchangers. They are divided into surface (recuperative and regenerative) and mixing. Surface type heat exchangers, in turn, are divided into shell-and-tube “pipe in pipe”, lamellar, shell-and-plate, twisted, submersible, irrigation, spiral.
