Water-Water / Steam-Water Plate / All-Welded / Flue Gas Heat Exchanger

Plate heat exchanger

plate heat exchanger is a highly efficient and compact heat exchange device. Its core consists of a series of stacked, corrugated metal plates separated by gaskets to form alternating flow channels. Hot and cold fluids flow through these narrow channels, creating intense turbulence under the influence of the corrugations. This effectively transfers heat from the high-temperature fluid through the plates to the low-temperature fluid. This device, with its high heat transfer efficiency, compact structure, and easy maintenance, is widely used in heating, cooling, chemical engineering, metallurgy, food and pharmaceutical industries, and many other fields.

Product Description

A plate heat exchanger is a highly efficient heat exchange device that utilizes plates and sealing gaskets within the plate heat exchanger to transfer heat between two different media. The plates are typically made of metal materials such as stainless steel or titanium alloy, and their surfaces often feature a series of grooves and protrusions to increase the heat exchange area.

As the two media flow through the two different channels of the plate heat exchanger, they form a very thin heat

exchange interface on the plate surface. Heat is transferred from one medium to the other, achieving heat transfer. Furthermore, the sealing gaskets within the plate heat exchanger ensure complete isolation between the two media, preventing cross-contamination.

The advantages of plate heat exchangers include high thermal efficiency, compact footprint, and easy maintenance, leading to their widespread use in many industrial fields.

System composition

Plate heat exchanger components

A plate heat exchanger primarily consists of heat transfer plates, sealing gaskets, fixed and movable pressure plates, clamping bolts, and end inlet and outlet pipes. The heat transfer plates are the core component, with a corrugated design that increases heat transfer area and fluid turbulence. Sealing gaskets prevent fluid leakage. The fixed and movable pressure plates are clamped together by clamping bolts, forming flow channels. End inlet and outlet pipes connect to external piping, guiding fluid in and out of the heat exchanger.

Plate heat exchanger process flow

The process flow of a plate heat exchanger is as follows: The cold and hot fluids enter the heat exchanger at either end and flow in parallel or countercurrent within the plate channels separated by sealing gaskets.

The fluids create intense turbulence within the narrow and complex channels between the plates, effectively disrupting the boundary layer and efficiently transferring heat from the high-temperature fluid to the low-temperature fluid through the metal plates. 

After the heat exchange is complete, the two media exit through the other outlet. This process is compact, highly efficient, and allows for rapid temperature control, making it suitable for a variety of industrial and residential applications, including district heating, refrigeration, chemical processing, and food and beverage.
