Brazed Plate Heat Exchanger

Heat Transfer Equipments Pvt. Ltd. is a Brazed Plate Heat Exchanger manufacturer in India, providing compact heat transfer solutions for heating, cooling, refrigeration, heat pump, oil cooling, and industrial process applications.

Brazed Plate Heat Exchangers are designed with corrugated metal plates joined through a brazing process to form separate flow channels for the fluids. The plate arrangement, materials, connection configuration, pressure rating, and heat transfer area can be selected according to the application requirements.

What Is a Brazed Plate Heat Exchanger?

A Brazed Plate Heat Exchanger is a compact heat transfer equipment that uses a series of corrugated metal plates to transfer heat between two fluids.

The plates are arranged to create separate flow passages for the hot and cold fluids. A brazing process joins the plates and forms a sealed heat transfer assembly without the need for conventional gaskets between individual plates.

This compact construction makes brazed plate heat exchangers suitable for applications where efficient heat transfer and space-saving equipment arrangements are required.

How Does a Brazed Plate Heat Exchanger Work?

The working principle is based on indirect heat transfer between two fluids flowing through separate channels.

Hot fluid enters one set of channels while the cold fluid flows through alternate channels. As the fluids move through the corrugated passages, heat passes through the metal plates from the hotter fluid to the colder fluid.

The plate pattern promotes fluid movement across the heat transfer surface and helps improve heat transfer between the two streams.

Heat transfer performance depends on factors such as flow rate, fluid properties, inlet and outlet temperatures, temperature difference, plate arrangement, pressure drop, and operating conditions.

Brazed Plate Heat Exchanger Design and Construction

A Brazed Plate Heat Exchanger is constructed as a compact plate assembly designed for the required thermal and mechanical conditions.

Heat Transfer Plates

Corrugated metal plates form the primary heat transfer surface. The plate thickness, pattern, number of plates, and material can be selected according to the application.

The corrugated arrangement also forms the flow channels through which the hot and cold fluids pass.

Brazed Joints

The individual plates are joined using a brazing process to create a sealed and mechanically stable heat exchanger assembly.

The brazed construction eliminates the requirement for conventional gaskets between the plates and provides a compact arrangement.

Fluid Connections

Connections are provided for the inlet and outlet of the two fluid circuits. Connection size and arrangement can be selected according to flow requirements and installation conditions.
