Phes heat exchangers
Plate heat exchangers are equipment designed for heat transfer between two media through a system of thin corrugated plates. This design increases the heat exchange surface area and creates flow turbulence, significantly enhancing process efficiency.
Operating principle
of a plate heat exchanger
The operating principle of a plate heat exchanger is based on heat transfer between two media that circulate through separate channels without mixing. These channels are formed by corrugated plates, which can be connected in different ways: by welding, brazing, or using rubber gaskets, depending on the type of device. Due to the temperature difference, heat is transferred from the hot medium to the cold one through the plate surface. The flows can move either in counterflow (opposite directions) or parallel flow (same direction), which affects the heat transfer efficiency.
How a plate heat exchanger is constructed
Plate heat exchangers, regardless of their design type (gasketed, brazed, or welded), consist of a set of plates through which the heat transfer medium flows. These plates can be made of various metals or alloys depending on operating conditions, allowing for the optimal material selection for a specific medium. The construction of heat exchangers includes connections for the working media and the possibility of disassembly for maintenance (in the case of gasketed models). The plate pack can be secured using tie bolts, welding, or brazing, depending on the device’s design. It is important to consider maximum temperature and pressure limits to ensure long-term and safe operation of the heat exchanger.
Cost calculation of a plate heat exchanger
The cost calculation of a plate heat exchanger depends on its thermal capacity, operating temperature and pressure, type and number of plates, construction material, and manufacturer. The main calculation steps include selecting the optimal heat exchange area, determining the required number of plates, and choosing the materials. Additional factors such as gasket type and installation method are then considered.
Applications of plate heat exchangers
Plate heat exchangers are widely used in utilities, the food industry, as well as in metallurgy, chemical, energy, sugar, and oil refining industries. Their popularity is due to high efficiency, compactness, and the ability to work with various media—from water and steam to aggressive chemicals.
Each industry has specific requirements for heat exchange equipment: in the food industry, sanitary standards and resistance to cleaning agents are important, while in oil refining, resistance to high temperatures and aggressive environments is crucial. A well-selected heat exchanger that considers process specifics ensures reliable and efficient operation, reducing maintenance costs and extending the equipment’s service life.
