Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing.

[0031] figure 1 A structural schematic diagram of the Cantor set fractal structure heat exchanger of the present invention is given. The invention relates to a heat exchanger with a Cantor fractal heat exchange tube bundle, which is composed of a Cantor fractal heat exchange tube bundle, a shell, a tube sheet and other main parts. The cross-sectional shape of the shell is generally rectangular, and the tube sheets 1 and 4 are respectively located on both sides of the shell 2 . The Cantor fractal heat exchange tube bundles 3 are spread out in a planar manner and arranged in a staggered manner, and their two ends are fixed and pass through the tube sheets 1 and 4 . The inlet and outlet of the shell-side fluid 5 are located on the shell 2, and the inlet and outlet of the tube-side fluid 6 are located on the tube sheets 1 and 4. In this way, the tube sheet can not only separa...

Abstract

The invention discloses a heat exchanger of a Cantor set fractal structure type. The heat exchanger comprises a heat exchange pipe bundle, a shell and pipe sheets, wherein the pipe sheets are arranged on the two sides of the shell, and the two ends of the heat exchange pipe bundle are fixed on the pipe sheets and penetrate through the pipe sheets. The heat exchange pipe bundle is at least one setof parallel pipe bundles with diameter consistent with characteristics of the Cantor set fractal structure. According to the invention, the shell space is fully utilized to distribute the heat exchange pipe bundles to the maximum extent in order to increase the heat exchange area. Meanwhile the heat exchange pipe bundles are distributed in a multi-stage staggered way, and the sections of the heatexchange pipe bundles are periodically changed, so that the field synergy of flowing heat exchange is greatly enhanced, the heat effectiveness of the heat exchanger is enhanced to the maximum extent,and the goals of efficiently exchanging heat and saving energy are achieved.

Description

technical field [0001] The invention relates to a flow heat exchange device, in particular to a Cantor set fractal structure heat exchanger with a Cantor set fractal structure characteristic heat exchange tube bundle designed for strengthening the comprehensive performance of flow heat exchange. Background technique [0002] Shell-and-tube heat exchangers have the advantages of high reliability, strong adaptability, and simple design and manufacture, and are widely used in petrochemical, energy, power, environmental protection and other industrial fields. Therefore, it is particularly important to optimize the design of the shell-and-tube heat exchanger to improve its flow heat transfer efficiency. [0003] Shell and tube heat exchangers usually arrange many parallel tube bundles in a shell, one fluid flows in the tubes, and the other fluid flows in the shell side, and the hot and cold fluids exchange heat through the heat exchange tube bundles. In order to improve the flow...
