Disk-shaped heat exchange pipe

Abstract

The invention discloses a dish-shaped heat exchange tube, which comprises an upper tube wall and a lower tube wall arranged end to end, the upper tube wall and the lower tube wall both include a front end, a middle end and an end connected in sequence, and the upper tube wall and the lower tube wall Both are arc-shaped; the front ends of the upper tube wall and the lower tube wall are two first arcs, the two first arcs intersect to form the tip, the ends of the upper tube wall and the lower tube wall are two second arcs, the two The second arc intersects to form the tip. The disc-shaped heat exchange tube in the present invention can effectively improve the comprehensive heat transfer characteristics of the heat exchange tube, not only meet the low cost of processing and installation, but also effectively strengthen the flow effect of the external fluid, improve the heat transfer performance of the heat exchange tube, and reduce the The wear and tear of the external fluid on the heat exchanger and the deposition of the external fluid improve the safety and economy of the heat exchange tube as a whole.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a dish-shaped heat exchange tube. Background technique [0002] As a device for exchanging heat without contact between two heat exchange media, the heat exchange tube is widely used in the fields of chemical industry, energy and power. In order to improve the economy of industrial production and enhance the safety and reliability of equipment, it is necessary to optimize the structure of heat exchange tubes. [0003] At present, most of the heat exchange tubes widely used in industry are circular and oval. Among them, the circular heat exchange tube is easy to process and the cost is low, while the elliptical heat exchange tube has lower flow resistance than the circular heat exchange tube. Higher heat exchange efficiency and easier to arrange. However, the flow resistance of circular and oval heat exchange tubes has room to decrease, and large wake vortices are easily...

AI Technical Summary

Problems solved by technology

However, the flow resistance of circular and oval heat exchange tubes has room to decrease, and large wake vortices are easily formed on the back flow surface, resulting in the deposition of fluid outside the tubes, and the heat exchange tubes are severely worn during operation, which greatly affects the flow rate of the heat exchange tubes.
