The company ZIKO<\/strong> is a representative of leading European manufacturers of heat exchangers<\/strong>.<\/p>\n\n\n\n

Most food industry enterprises use heat exchangers in their production lines, which allow products to be quickly and efficiently cooled or heated<\/strong>. The operating principle of this equipment is not particularly complex and is usually designed in accordance with the individual requirements<\/strong> of a specific industrial installation.<\/p>\n\n\n\n

So, what is a heat exchanger, how does it work, and what are its main types?<\/p>\n\n\n\n

Heat exchangers are devices that enable heat transfer between specific media<\/strong> (liquids or gases). In modern industrial installations, pressurized steel heat exchangers<\/strong> of various designs are used, all based on a very similar operating principle. Their construction primarily depends on the method of heat transfer, which can be direct (contact)<\/strong> or indirect (non-contact)<\/strong>. Heat exchangers are designed according to the specific installation and the working medium involved.<\/p>\n\n\n\n

A heat exchanger provides heat transfer between fluids at different temperatures. Its operating principle is based on heat transfer by convection and conduction<\/strong> (heat exchange between liquids and gases). A high-temperature fluid releases thermal energy by convection to the wall or surface of a tube or plate. The heat then passes through the tube wall or plate and is ultimately absorbed by the colder fluid.<\/p>\n\n\n\n

The exchange of thermal energy can occur, depending on the type of heat flow, by direct contact<\/strong> \u2014 when the media come into direct contact with each other \u2014 or by indirect (non-contact) transfer<\/strong>, when the media are separated from one another. In addition, the operating scheme of a heat exchanger may vary depending on the flow arrangement<\/strong> used in different systems.<\/p>\n\n\n\n
