Plate Heat Exchanger 304 Stainless Steel Titanium Plate Detachable Manufacturer Direct Supply Central Heating Heat Exchanger Plate Heat Exchanger

Plate heat exchangers form alternating flow channels by stacking corrugated metal plates. Cold and hot fluids flow in opposite directions in adjacent channels, and heat is transferred from high-temperature fluids to low-temperature fluids through the plates. The two fluids never mix. ‌‌
structural composition
Plate group: It is composed of a series of thin metal plates (with a thickness of about 0.4-0.8mm) stamped into a corrugated shape and stacked together. The four corners of the plates are perforated to form fluid distribution and collection pipes. ‌‌

Sealing system: Rubber sealing gaskets are used to separate the plates, and the surrounding areas are sealed with gaskets to prevent fluid leakage and mixing. ‌‌
Framework structure: The plate group is installed between the fixed clamping plate and the movable clamping plate, fixed by clamping bolts, and can adjust the heat exchange area by increasing or decreasing the number of plates
Heat transfer process
Fluid flow: Cold and hot fluids enter adjacent odd and even layer channels respectively, usually using a counter current arrangement (opposite flow direction) to increase the temperature difference. ‌‌‌
Heat transfer: Heat is conducted from a high-temperature fluid to a low-temperature fluid through a thin metal plate of 0.5-0.6mm, which belongs to inter wall heat transfer. ‌‌‌
Turbulence Enhancement: The corrugated plate design generates turbulence in the fluid at lower Reynolds numbers (Re=50-200), disrupting the laminar bottom layer and increasing heat transfer efficiency by 3-5 times compared to the shell and tube design
Main Features
High heat transfer efficiency: The heat transfer coefficient can reach 800-3500W/(m ² · K), and the heat recovery rate can reach over 90%. ‌‌
Encyclopedia
Compact structure: The heat transfer area per unit volume is 2-5 times that of the shell and tube type, and the footprint is about 1/5-1/10 of the shell and tube type. ‌‌
Widely applicable: Suitable for liquid-liquid and liquid vapor heat exchange, commonly used in industries such as HVAC, chemical, food, and power
