How to choose the right spiral heat exchanger

Currently, various types of heat exchangers are used in industrial enterprises for system heating, among which spiral varieties are particularly popular. These heat exchangers have many advantages, among which are ease of installation, small size and ease of use. For the correct choice of this equipment, it is necessary to calculate the spiral heat exchanger, which takes into account the various parameters of the device itself and the production conditions.The design of the spiral heat exchanger assumes the presence of two or four metal strips, which are twisted around the central pipe. With the help of special pins, the strips are connected to each other, forming several channels with the same width. In most cases, the central pipe in spiral heat exchangers consists of two parts forming the outlet and inlet manifolds together. All elements of the heat exchanger are located in a cylindrical housing. On the side of the housing there are pipes formed by sheets welded along the collectors.Due to the separation pins in the design of the described heat exchangers, a sufficiently high level of turbulence is formed even at low speeds. In addition, the media in spiral heat exchangers move in circles, while providing good heat transfer even in conditions of contamination or high viscosity. The design features of the equipment also make it possible to reduce the deposition of impurities. Thanks to the details described above, heat exchangers of this type are able to perform their functions, having a fairly compact size.What to look for when choosing a spiral heat exchanger:- Features of technological processes used in the framework of production.- The necessary heat exchange indicators for the performance of production tasks.- The level of pollution of the media with certain substances.- Media used in the framework of production. This factor affects the choice of a specific material that the heat exchanger may consist of (carbon steel, stainless steel, and so on).- During the selection process, many other production parameters should also be taken into account, including flow direction, pressure, temperature, etc. spinaura
