Shell and tube heat exchanger
As a traditional heat exchanger, shell and tube heat exchanger has a long history of application. It is widely used in many industrial sectors, especially in chemical, petroleum, energy and other industries. It consists of many tubes, which form the heat transfer surface of the heat exchanger, so it is also known as tubular heat exchanger.
Air cooler/air preheater
Air cooled heat exchanger is a kind of heat exchanger which uses air, flue gas, water, steam, solution, oil and other media to cool or heat the flowing flue gas/air. It can adopt the smooth tube type, but more fin tubes are used as heat transfer elements. Because of the use of fins, it has the characteristics of high heat transfer efficiency, small volume, compact structure, large adaptability and light weight. The heat exchanger is widely used in air separation equipment, petrochemical industry, chemical fertilizer, natural gas, heavy machinery, electronics and other fields.
Fixed tube-plate heat exchanger
The tube plates at both ends of the tube bundle are welded with the shell. The utility model has the advantages of simple structure, low manufacturing cost, small temperature difference of cold and hot flow, relatively clean materials outside the pipe and not easy to scale. When the temperature difference is slightly larger and the shell side pressure is not too high, an elastic compensation ring can be installed on the shell to reduce the thermal stress.
