What factors affect the performance of plate heat exchangers

  Plate heat exchanger equipment is increasingly used in various industries, so what factors will affect the performance of plate heat exchangers?

the performance of plate heat exchangers(1) Problems with plate heat exchangers: When many users purchase plate heat exchangers, they only provide the heat exchange area, and do not provide specific data such as the flow rate of the medium and the temperature of the inlet and outlet. As a result, the area of the purchased equipment model It is correct, but the process combination is unreasonable. Even if the area is increased on the basis, the equipment cannot meet the budget requirements and effects.

(2) System configuration: The plate heat exchanger only follows the role of heat transfer and follows the law of energy conductance (the heat released by heat measurement and the heat absorbed by rain and cold measurement).In many cases, there is not enough cold-side cooling water to remove the heat from the heating system on the hot side. If the amount of water and the water temperature are not enough, the temperature on the hot side will not drop. Then no matter how large the heat exchanger is useless.

(3) According to the characteristics and applicable scope of the material, the plate material is correctly and reasonably selected. It is necessary to consider the nature of the heat exchange medium, the operating conditions (including chloride content, pH value, operating temperature, operating pressure, gap operation or continuous operation), as well as the forming processability and corrosion resistance of the material.Commonly used materials for plates are cold-rolled sheets such as austenitic stainless steel, titanium and titanium alloys, nickel and nickel alloys and copper.

(4) The chemical composition, mechanical properties and other technical requirements of materials shall comply with the provisions of corresponding standards.
