AI Technical Summary

Technical Problem

Cylindrical heat exchangers have limited heat exchange area, which affects their heat exchange effect and efficiency, and their structural design is inadequate under high pressure and high temperature conditions.

Method used

A cylindrical heat exchanger is designed, which uses an upper cover plate, a lower cover plate, an inner side plate, and an outer side plate to form a hollow cylindrical heat exchange cavity. A partition plate divides it into an alternating first flow channel and a second flow channel. Heat transfer fins and flow guide holes are set in the flow channels to increase the contact area and the uniformity of fluid flow.

Benefits of technology

It significantly improves the pressure-bearing capacity and heat exchange area per unit volume, enhances the heat exchange efficiency with the outside atmosphere, makes the fluid flow more uniform, reduces flow dead zones and pressure drop, and improves the heat exchange effect.

Abstract

The present disclosure relates to a cylindrical heat exchanger, comprising an upper cover plate, a lower cover plate, an inner side plate, an outer side plate, a first fluid inlet end, a first fluid outlet end, a second fluid inlet end, a second fluid outlet end and a plurality of partitions, the upper cover plate, the lower cover plate, the inner side plate and the outer side plate together enclose a closed hollow cylindrical heat exchange cavity, along the height direction of the heat exchange cavity, the plurality of partitions are arranged in the heat exchange cavity at intervals and are used for separating the heat exchange cavity into a plurality of first flow channels and second flow channels arranged alternately from top to bottom; the first fluid inlet end, the first fluid outlet end, the second fluid inlet end and the second fluid outlet end are connected with the outer side plate, and each first flow channel is in communication with the first fluid inlet end and the first fluid outlet end, and each second flow channel is in communication with the second fluid inlet end and the second fluid outlet end. The annular inner passage can further increase the heat exchange area of the unit volume core, save space under certain heat exchange area conditions, and facilitate installation and support.
