What Are The Arrangements of Heat Exchange Tubes?

Heat exchange tubes are one of the main components in heat exchangers, and their arrangement has an important impact on the performance of heat exchangers. The following are several common arrangements of heat exchange tube.

Single-row Tubes

Single-row tubes are heat exchange tubes arranged separately to form a row. This arrangement has the advantages of simple structure, easy manufacturing, maintenance and cleaning. However, its heat exchange area is relatively small, and it is prone to scaling and contamination.

Double-row Tubes

Double-row tubes are two rows of heat exchange tubes arranged in parallel directions, leaving a certain gap in the middle. This arrangement has the advantages of large heat exchange area, high thermal efficiency, and small flow resistance, and is suitable for high-demand industrial production. However, its structure is relatively complex, the processing is difficult, and its cost is relatively high.

Spiral Tubes

Spiral tubes are a specified number of heat exchange tubes bent into a spiral shape and arranged along the axis. This arrangement has the advantages of high heat exchange efficiency, small flow resistance, compact structure, and low resistance, and is suitable for high-flow and high-viscosity media. However, its processing is difficult and has high manufacturing requirements.

Plate Heat Exchange Tube

Plate heat exchange tube is a certain number of flat plate heat exchange tubes stacked together. This arrangement has the advantages of compact structure, high heat exchange efficiency, and low flow resistance. It is suitable for media with large flow and small pressure drop. However, its manufacturing process is relatively complicated and requires special plate heat exchanger elements.

Ring Tube

The ring tube is to arrange the heat exchange tubes in a ring to form a ring pipe. This arrangement has the advantages of compact structure, high heat exchange efficiency, and low flow resistance. It is suitable for heat exchange of small flow and high temperature media. However, its manufacturing difficulty is relatively large, and it is necessary to ensure the dimensional accuracy and sealing performance of the heat exchange tube.

Basket Type

The basket type is to place a certain number of heat exchange tubes vertically in a basket-shaped container. This arrangement has the advantages of compact structure, easy cleaning, and high heat exchange efficiency. It is suitable for viscous media. However, its manufacturing difficulty is relatively large, and it is necessary to ensure the manufacturing accuracy of the basket-shaped container and the uniformity of the arrangement of the heat exchange tubes.
