The important index of the selection parameters of the plate heat exchanger unit

Plate heat exchanger is a kind of heat exchange equipment widely used in industrial production field. It has the advantages of small size, high heat star transfer efficiency, simple structure and so on, so it is widely used in many industrial production. In the selection of plate heat exchanger unit, we must consider some important selection parameters and indicators to ensure the performance and operation of the equipment, this paper will be an important selection parameters of the plate heat exchanger unit, to help readers make the right decision in the actual purchase.

Plate Heat Exchanger

First of all, one of the more important indicators in the selection parameters of plate heat exchanger units is the heat exchange area. The heat exchange area is an important parameter to determine the heat conduction intensity of the heat exchanger, and it is also a determinant of the size of the heat exchanger. The larger the heat exchange area, the higher the heat transfer efficiency, but the volume and cost of the equipment will also increase accordingly. Therefore, when washing, it is necessary to determine the appropriate heat transfer area according to the requirements of the specific application field, the physical properties of the fluid and the process parameters.
Secondly, the selection parameters of the plate heat exchanger unit also need to consider the flow rate and pressure drop of the fluid, the flow rate of the fluid refers to the volume or mass of the fluid through the heat exchanger in a unit time, which is one of the basic input parameters of the heat exchanger design. The size of the flow determines the fluid speed and flow state inside the heat exchanger, which affects the heat conduction and fluid light force. Pressure drop refers to the positive force loss generated by the fluid in the heat exchanger process, which directly affects the performance and operation of the heat exchanger. Therefore, when selecting a plate heat exchanger unit, it is necessary to determine the appropriate flow rate and pressure drop according to the specific conditions of use and process requirements.
Third, the selection parameters of plate heat exchanger units also need to consider plate spacing and plate type. Plate spacing refers to the spacing between two adjacent plates in a plate heat exchanger, which directly affects the heat exchange area and the width of the fluid channel inside the heat exchanger. Under normal circumstances, the smaller the plate spacing, the larger the heat transfer area, the better the heat conduction effect, but the fluid channel will also narrow accordingly, increasing the positive force loss of the fluid. Plate type refers to the shape and structure of the plate used in the plate heat exchanger, such as flat plate, honeycomb type, corrugated type, etc. Different plate types have different effects on heat transfer performance and structural characteristics, which need to be selected according to specific requirements.

Fourth, the selection of plate heat exchanger unit also needs to consider the physical properties of the fluid and process requirements, the physical properties of the fluid include the temperature, pressure, viscosity, density and other parameters of the fluid, which directly affect the design and performance of the heat exchanger. Process requirements include fluid heat transfer temperature difference, heat transfer efficiency, leakage requirements, etc. These requirements will also affect the selection and design of the heat exchanger, therefore, in the selection of plate heat exchanger units, it is necessary to fully understand the physical properties of the fluid and process requirements, and fully communicate and negotiate with the equipment manufacturer to determine the appropriate selection parameters.

Fifth, the selection parameters of plate heat exchanger units do not need to consider the material and corrosion resistance of the equipment. In different industrial production, the composition and nature of fluids are different, and some fluids may be throttling. Therefore, it is necessary to select the appropriate material according to the composition and nature of the fluid, and ensure that the equipment has sufficient corrosion resistance to ensure the long-term stable operation of the equipment.
