Plate heat exchangers are a type of heat exchanger, primarily consisting of a series of corrugated metal plates stacked together to form a new type of heat exchanger. The plates within the apparatus are arranged to create thin rectangular channels, through which heat exchange occurs. So, what are the principles behind plate heat exchangers? What are the advantages of plate heat exchangers over shell-and-tube heat exchangers? Let's find out below.

What are the structural principles of plate heat exchangers?

The structural principle of a plate heat exchanger involves a combination of components. It refers to the arrangement of removable corrugated thin plates within a plate heat exchanger, sealed with gaskets at specific intervals. These plates are then clamped together using special frames and tension screws. The four corner holes of the plates and gaskets serve as fluid distribution and collection channels, allowing for the rational separation of cold and hot fluids and enabling heat exchange through the plates.

What are the working principles of plate heat exchangers?

The working principle of plate heat exchangers involves heat exchange through the plates, with the working airflow passing through the channels between two plates. Intermediate partition plates sequentially separate the cold and hot fluids in the channels, where heat exchange occurs on these plates.
