    The plate heat exchanger is mainly composed of plates, compaction plates and other components. The plate still plays a relatively important role in the structure of the plate heat exchanger. Its material selection largely determines the corrosion resistance of the heat exchange equipment. And operating efficiency, so we have a clear understanding of their stiffness requirements when selecting plate heat exchanger plates.
    The rigidity of the plate heat exchanger plate refers to the ability of the plates to be deformed against the effects of different pressure media on the two sides under the clamping action of the fixed pressure plate and the interactive pressure plate after the plates are assembled in accordance with the requirements. Under normal operating conditions of plate heat exchangers, in addition to the strength required to meet the plate, the plate also needs stiffness to control the gradual deformation of the plate.

    In order to allow the heat exchange medium to run uniformly in the liquid layer in the plate channel, to ensure the heat exchange efficiency. According to the operating principle of thermal expansion and contraction, the primary reason for the expansion or contraction of the plate is the increase or decrease in the temperature in the plate heat exchanger. However, the expansion or contraction of the plate will also be affected by the fixed compression plate and the movable pressure. Two-layer constraint for tight plates.
    When the thermal expansion and contraction of the plate heat exchanger cannot be performed freely, this requires that the heat transfer plate should have sufficient stiffness and pressure resistance. Therefore, the rigidity of the plate heat exchanger plate depends not only on the density and accuracy of the support point orientation, but also on the plate thickness, width and other various factors.
