A graphite heat exchanger is a type of heat transfer equipment made from graphite, widely used in industries like chemical processing, pharmaceuticals, and metallurgy for handling corrosive media. Graphite offers excellent corrosion resistance, high-temperature stability, and good thermal conductivity, making it ideal for harsh environments involving acids, alkalis, and other aggressive substances.

Graphite heat exchangers come in various designs, including tubular, plate, and block types. Tubular designs suit high-temperature and high-pressure conditions, plate types offer high heat transfer efficiency, and block types are compact and easy to maintain. They work by transferring heat from one medium to another through graphite, while maintaining the chemical stability of the media.

Advantages include:

• Corrosion resistance: Suitable for diverse chemical environments.
• High thermal conductivity: Efficient heat transfer.
• Long lifespan: Durable graphite material.

Drawbacks include graphite’s brittleness, which limits mechanical shock resistance, and relatively high manufacturing costs. Graphite heat exchangers are commonly used in applications like chlor-alkali production and sulfuric acid processing, making them ideal for complex chemical processes.
