Abstract

A new type of heat exchange tube, the heat exchange tube includes: flow channel (1), tube wall (2), tube wall (3), tube wall (4); the cross-sectional shape of the tube is composed of three equal circles with a radius of 25mm Formed by two circumcisions; the heat exchange tubes are composed of two different arrangements: regular triangle arrangement and regular hexagonal arrangement. The unique shape of the heat exchange pipe of the invention can increase the intensity of turbulent flow, strengthen the heat exchange effect, and improve the heat exchange performance. Compared with ordinary round pipes, the heat exchange coefficient is increased by nearly 50%. At the same time, the structure is relatively simple, it is not easy to scale, and it is more convenient to clean after scaling.

Description

technical field

[0001] The invention belongs to the technical field of refrigeration / energy, and relates to a novel heat exchange tube, in particular to a special-shaped heat exchange tube which strengthens fluid disturbance and increases the heat transfer area density of a heat exchanger. Background technique

[0002] Special-shaped heat exchange pipes, as a device to improve the efficiency of heat exchangers, have been widely used in the fields of energy / refrigeration / chemical industry in recent years, but there is still a lack of theoretical guidance in design and manufacture, and insufficient data in practical applications. Various manufacturers produce different types of special-shaped heat exchange pipes, but there is no relevant information on the reliability of the pipes, and the test data is yet to be verified.
