Quick-Assembly Plate Heat Exchanger

A plate heat exchanger is assembled by stacking numerous corrugated thin plates, spaced at fixed intervals and sealed around their perimeters with gaskets, then clamped together using a frame and compression screws. The four corner holes in each plate and gasket form fluid distribution and collection manifolds, while simultaneously separating the hot and cold fluids so that they flow through the channels on either side of each plate, enabling heat exchange across the plates.

Product Description

Structural Principle
Disassembly of the Plate Heat Exchanger Structural Diagram
A detachable plate heat exchanger consists of numerous corrugated thin plates, stamped to a specific profile, sealed around the perimeter by gaskets, and stacked between a frame and compression bolts. The four corner holes in each plate and gasket form fluid distribution and collection manifolds, while effectively separating the hot and cold fluids so that they flow through the channels on either side of each plate, enabling heat exchange across the plates.
The optimized design calculation for plate heat exchangers involves, under the condition of a known temperature‑difference ratio NTUE, appropriately determining the unit’s type, flow configuration, and heat transfer area so that NTUp equals NTUE.

Design Features
1. High efficiency and energy savings: Its heat transfer coefficient ranges from 3,000 to 4,500 kcal/m²·°C·h, which is 3 to 5 times higher than that of shell-and-tube heat exchangers.
2. Compact structure: The plates of a plate heat exchanger are arranged closely together. Compared with other types of heat exchangers, plate heat exchangers occupy less floor space and volume; for the same heat transfer area, a plate heat exchanger requires only one-fifth the space of a shell-and-tube heat exchanger.
3. Easy to clean and convenient to disassemble: Plate heat exchangers are clamped together by tightening bolts, making them easy to assemble and disassemble; they can be opened at any time for cleaning. Moreover, thanks to their smooth plate surfaces and high turbulence, fouling is less likely to occur.
4. Long service life: Plate heat exchangers are fabricated from stainless steel or titanium alloy plates, offering resistance to a wide range of corrosive media. The gaskets can be easily replaced, and the units can be conveniently assembled, disassembled, and maintained.
5. High adaptability: The plates of a plate heat exchanger are independent components, allowing the flow paths to be freely added or removed as needed, with a wide variety of configurations; thus, they can accommodate a broad range of process requirements.
6. No cross‑contamination: The sealing grooves of the plate heat exchanger are equipped with drain channels, preventing any media from mixing; even in the event of a leak, the fluid is always discharged outward.
