Technical Field

[0002] In the production of petroleum, chemical industry, light industry, pharmaceutical industry, energy and other industries, it is often necessary to heat low-temperature fluids or cool high-temperature fluids, vaporize liquids into steam or condense steam into liquids. These processes all need to be completed by heat exchangers. Graphite heat exchangers have the advantages of strong corrosion resistance, high thermal conductivity, and high operating temperature, and are widely used in industry. The existing technology has the following problems:

The existing devices cannot efficiently transfer heat, resulting in poor cooling effects. At the same time, the existing devices cannot directly perform environmentally friendly exhaust, making it impossible to filter the transmitted gas, resulting in low safety. Utility Model Content
