Description

Technical field [0001] The invention relates to the field of heat exchangers, in particular to a glass fiber reinforced plastic heat exchanger. Background technique [0002] Shell and tube heat exchangers are widely used in industries, food, and chemical industries. In order to ensure the heat transfer effect of traditional heat exchangers, only metal materials can be used as heat exchange tubes. However, welding problems cause the entire set of equipment to only use metal structures, resulting in very high prices for shell and tube heat exchangers. [0003] With the rapid development of the FRP industry, its material properties have been greatly improved. Shell and tube heat exchangers made of FRP can fully meet the requirements of economy, heat resistance, strength, aging and corrosion resistance of shell and tube heat exchangers. . The density of FRP is 1.4-2.1 tons / m3, while the density of 316L is 8.01 tons / m3, and the density of TA is 4.5 tons / m3. The use of FRP materials c...
