0000010097 00000 n 0000054892 00000 n 0000034918 00000 n To understand heat exchanger thermodynamics, a good starting point is to learn about the three ways in which heat can be transferred – conduction, convection, and radiation. These are typically made from steel or titanium, and you can see they have a pattern grooved or stamped into them. A plate exchanger consists of a series of parallel plates that are placed one above the other so as to allow the formation of a series of channels for fluids to flow between them.

The space between forms ducts in which the two fluids are allowed to flow, exchanging heat through the plates. The U-value is the rate of heat transfer through a plate divided by the difference in temperature across the whole plate structure.

Above is an example of a real world heat exchanger plate. These patterns are going to strengthen the plates as well as increase the heat transfer surface area by creating a very turbulent flow inside them. Welded, semi-welded and brazed heat exchangers are used for heat exchange between high-pressure fluids or where a more compact product is required. 0000020280 00000 n The plate heat exchanger (PHE) is a specialized design well suited to transferring heat between medium- and low-pressure fluids. Plate Heat Exchangers were first produced in the 1920s and have since been widely used in a great number of sectors. 0 Our manufacturers' test Heat Exchanger not only passed the government's mandated 10,000 firing cycles, it has continued to perform flawlessly after 1,487,000 test cycles! startxref This heat transfer takes place through a sectional division facilitated by plates. xref 6 26
