Plate heat exchangerA critical aspect of plate heat exchangers is the sealing between plates. The sealing grooves, end plates, and the inner side of the compression plates contribute to significant pressure drop. The pressure drop in the channels and inlets/outlets often exceeds design specifications, sometimes by several times, severely impacting system flow rate and temperature requirements.
In heating systems, a large pressure drop on the hot side leads to insufficient primary side flow, rendering the heat source ineffective and failing to meet the required secondary side outlet temperature. Direct liquid contact: a key feature involves the connection of high-pressure and low-pressure materials. This can cause abnormal pressure and temperature in the system and, if the substance is corrosive, may cause corrosion in other equipment in the pipeline. Fluid dynamics issues generally occur in turning areas or possibly in the two sealing areas. Failure to meet temperature requirements: a primary characteristic is that the outlet temperature is too low to satisfy the design requirements.
Plate heat exchangerThe heat transfer area and process configuration can be adjusted based on site requirements. Plate heat exchangers are widely used in metallurgy, petroleum, chemical, power, fiber, pharmaceutical, food, paper, and heating industries. They can be used in heating, cooling, evaporation, and condensation applications. The primary structure comprises inlet heat transfer fins, sealing rubber plates, clamping bolts, and compression plates. They are resistant to various corrosive substances.
Plate heat exchangerHigh heat transfer efficiency is achieved as hot and cold materials flow through adjacent channels for heat exchange. The curved corrugations on the plates create turbulent flow, resulting in higher heat exchange efficiency. This offers high efficiency and energy savings; the thermal conductivity can reach 3000-4500 kcal/m2·°C·h. At the same flow rate, plate heat exchangers offer more than 3 times the efficiency of shell and tube heat exchangers.
