Tubular coolers play a pivotal role in many industries, especially in the chemical, metallurgical and other industries, then the structure of the equipment is also very different. Generally speaking, there are three different structural forms in terms of structure and use. The common feature is that each heat transfer surface is made of metal plates. One fluid flows through this pipe, and the other fluid flows through adjacent pipes. Several different structures of the column tube cooler are described below.
The most widely used tube-and-tube cooler is the plate and frame heat exchanger. It is a set of formed plates combined on a frame. In order to meet the requirements of different flow rates, heat transfer and temperature, series and parallel can be configured in a wide range. Circuit, but structural limitations make it use pressure and temperature are not high. The second type is a helical tube cooler, which is formed by winding two parallel long plates into a spiral shape and welding on adjacent staggered end faces to form a flow channel. Since the channel itself is spiral, a secondary circulation can be performed. Therefore, a larger heat transfer coefficient can be obtained under laminar flow conditions, and scaling is not easy. The third type is a plate-and-plate heat exchanger. Its structure is that the welded flow channels are longitudinally installed in the housing. Because the flow channels are equipped with gaskets, these plates can withstand large internal pressure. The film is easy to disassemble, convenient for cleaning and inspection.
The types of tube-and-tube coolers are simply mentioned. In fact, whether it is a tube-type cooler or a heat exchanger, we have seen more than just these types. Some have already matured heat exchangers. We have seen a lot, and there are relatively few new and special heat exchangers being developed, but they do exist.
