Basic knowledge: How are heat exchangers classified based on the shape and structure of their heat transfer surfaces?

Shell-and-tube heat exchangers, plate heat exchangers, coiled tube heat exchangers, tube-wound heat exchangers. . .

It is divided into: (1) Tubular heat exchangers: Tubular heat exchangers transfer heat through the wall of the tubes. Depending on the structure of these heat transfer tubes, they can be classified into shell-and-tube heat exchangers, coiled tube heat exchangers, finned tube heat exchangers, and so on. Tubular heat exchangers are the most widely used. (2) Plate heat exchangers: Plate heat exchangers transfer heat through their plates; based on the structure of these heat transfer plates, they can be classified into flat plate heat exchangers, spiral plate heat exchangers, plate-fin heat exchangers, and thermal plate heat exchangers. (3) Special-shaped heat exchangers: These are heat exchangers designed with a special structure to meet the particular requirements of a specific process. Such as rotary heat exchangers, heat pipe heat exchangers, etc.
