BR085 Plate Heat Exchanger Accessories

A plate heat exchanger is a highly efficient and compact thermal exchange device widely used in industries such as chemical, pharmaceutical, HVAC, and food processing. Its core function involves heat transfer through thin layers of fluid between metal plates. The following are its main components and functions:

1. Heat Transfer Plates
Material: Typically made of stainless steel (e.g., SUS304, SUS316L), titanium alloy, or copper alloy, offering strong corrosion resistance.
Structure: Surfaces are pressed into corrugated patterns (e.g., herringbone, fishbone) to increase fluid turbulence and enhance heat transfer efficiency.
Function: Serve as channels for heat exchange media, facilitating heat transfer through contact between plates.
2. Gaskets
Material: Rubber (EPDM, fluororubber), silicone, or polytetrafluoroethylene (PTFE), resistant to high temperatures and corrosion.
Role: Seal gaps between plates to prevent medium leakage while allowing thermal expansion of the plates.
Feature: Require regular replacement to maintain sealing integrity.
3. Frame Components
Fixed Plate: Secures one end of the plate stack and supports the overall structure.
Floating Plate: Alternates with fixed plates and connects via a clamping mechanism for easy disassembly and cleaning.
Deflector Plate: Guides fluid for even distribution, reduces dead zones, and optimizes flow paths.
4. Clamping System
Type: Bolt-type, hydraulic, or screw-type.
Function: Applies mechanical force to compress plates, ensuring tight gasket contact and withstanding operational pressure.
5. Connecting Pipes
Inlet/Outlet Nozzles: Connect to external pipelines to transport hot and cold media (e.g., water, steam, oil).
Support Beam/Crossbeam: Enhances frame rigidity and distributes loads.
6. Accessory Components (Optional)
Temperature Sensors/Pressure Gauges: Monitor operational parameters.
Filters: Protect plates from clogging by impurities.
Self-Cleaning Devices: Remove fouling through backflushing or brushing.
