Plate Heat Exchanger (PHE) is a compact, efficient heat transfer device designed for heating, cooling, or heat recovery between two fluids. Comprising a series of corrugated metal plates stacked together, it creates multiple flow channels that maximize surface area and turbulence, resulting in exceptional heat transfer efficiency. Ideal for applications requiring precise temperature control, energy savings, and space optimization, PHEs are widely used in HVAC, industrial processes, and renewable energy systems.
Due to the special effect of the plate corrugated surface, the plate heat exchanger makes the fluid flow along the corrugated channel, and the direction of its velocity changes continuously, causing the fluid to arouse a strong end motion at a small flow rate, thus strengthening the transmission. heat process. The heat transfer capacity is effectively improved, and it has the outstanding advantages of compact structure, low metal consumption, high operational flexibility, and long service life.
The process of the heat exchanger is assembled by many plates according to certain process and technical requirements of the buyer. When assembling, the plates A and B are arranged alternately, and a mesh is formed between the plates. The gasket seals the hot and cold media in the heat exchanger, and at the same time reasonably separates the hot and cold media without mixing them. The hot and cold fluids in the channel Interval flow can be countercurrent or downstream as required. During the flow, the hot and cold fluids exchange heat through the plate surface to achieve the desired effect.
There are many process combinations of plate heat exchangers, all of which are realized by using different reversing plates and different assemblies. Process combination forms can be divided into single process, multi-process and mixed process forms.
High Efficiency: Heat transfer coefficients higher than shell-and-tube
Compact Size: 50-80% smaller footprint than equivalent shell-and-tube units
Easy Maintenance: Plate pack can be opened for inspection and cleaning
Flexibility: Capacity easily increased by adding plates
Low Fouling: High turbulence reduces scaling and deposits

The plate heat exchanger consists of a frame (fixed and movable end plates, tightening bolts) and plate pack (corrugated plates with gaskets or laser-welded seams). Plates are typically made of stainless steel (SS304/SS316L) or other alloys, with patterns optimized for specific duties. Fluids flow alternately between plates, transferring heat through thin metal walls. Designs include gasketed, brazed, and welded types.
