Wide channel plate heat exchanger

What is Wide channel plate heat exchanger working principle？

The wide channel plate heat exchanger is a product specially developed for heat exchange conditions of various solid, crystal, fiber, slurry substances and high-viscosity media. Due to the special design of the heat exchange plates, it ensures smooth wide gap channels, smooth fluid flow, no retention, no dead zones and no channel blockage. The special feature of this type of plate lies in its unique corrugated shape where the width of the flow channels between the plates can reach 6-16mm.

What is plate heat exchanger

The detachable plate heat exchanger is primarily constructed from stamped corrugated metal plates, gaskets, and a frame. These plates are arranged alternately to form a network of fluid channels, allowing hot and cold media to transfer heat through the plate walls in counter-flow or parallel-flow configurations.
It achieves a heat transfer coefficient of 3000–4500 kcal/m²·°C·h, offers thermal efficiency 3 to 5 times higher than shell-and-tube heat exchangers, and requires up to 80% less floor space.
To enhance corrosion resistance, materials such as stainless steel or titanium alloy are used. The plate pack can be quickly disassembled and reassembled using clamping bolts. Together with drainage channels and replaceable gaskets, this design enables easy cleaning and maintenance.
The unit supports flexible configuration of flow arrangements and heat transfer area, making it suitable for applications involving high temperatures (≤200°C), medium pressure (≤1.6 MPa), and corrosive media.

Application scenarios of wide channel plate heat exchangers

Compared with the common plate heat exchanger, the plate spacing is larger and the cross-sectional area of the single flow channel is larger. Due to the large plate spacing, the cross-sectional area of a single flow channel of the plates is much larger than that of a general plate heat exchanger. This has a more obvious advantage for some liquids with high viscosity and working conditions with large medium flow rates. On the cold fluid side, a medium flow channel with contact points is formed between the plates for the circulating water to pass through, while on the hot fluid side, a medium channel without contact points is formed between the plate groups It ensures the smooth passage of liquid containing solid particles, thus resulting in small pressure loss and uniform fluid distribution.

Heat exchange principle

Single-flow structure: Only two plates do not conduct heat - head and tail plates

Double-process structure: Each process has three plates that do not conduct heat.
