A floating finned tube heat exchanger

By setting baffles and elastic tube bundles in the floating finned tube heat exchanger, the fluid flow path is extended, and the shell-side fluid-induced vibration is utilized to solve the problems of small heat exchange area, short path and poor automatic descaling effect of existing heat exchangers, thus achieving efficient heat exchange and automatic cleaning functions.

AI Technical Summary

Technical Problem

Existing heat exchange devices suffer from problems such as small heat exchange area, short heat exchange path, poor vibration uniformity, poor automatic descaling and defrosting/de-icing effects, and insufficient combination flexibility.

Method used

A floating finned tube heat exchange device is designed, which divides the shell into two chambers by setting a baffle inside the shell, and sets multiple elastic tube bundles in series or parallel in each chamber. The finned tubes and heat exchange tubes are connected by U-shaped bends and combined tubes to extend the fluid flow path. Automatic descaling and defrosting are achieved by using shell-side fluid-induced vibration.

Benefits of technology

It improves heat exchange efficiency, increases heat exchange area and fluid flow path, achieves automatic descaling and defrosting, and has high flexibility in use.

Abstract

The application discloses a floating finned tube heat exchange device, and relates to the technical field of heat exchange equipment. The device comprises a shell, a vertical partition plate arranged in the shell, and a gap between the top end of the partition plate and the top plate of the shell. The partition plate divides the shell into a first chamber and a second chamber. A plurality of first elastic tube bundles are arranged in the first chamber in series or in parallel, and a plurality of second elastic tube bundles are arranged in the second chamber in series or in parallel. The first elastic tube bundles and the second elastic tube bundles each comprise a plurality of finned tubes connected in sequence. Two finned tubes connected in sequence are connected through a first combined tube. The first combined tube comprises a first arc-shaped flow guide tube, a first connecting tube and a second arc-shaped flow guide tube connected in sequence. The floating finned tube heat exchange device improves the heat exchange effect of the heat exchange device, and improves the automatic descaling and frost and ice removing effects of the heat exchange device.
