Problems solved by technology

[0003] (1) The heat transfer area per unit volume is small and the compactness is poor
Due to the installation, the tubes in the tube bundle cannot be closely arranged
Although the shell and tube heat exchanger has a large volume, the total heat exchange area is small, so the economic effect is poor
[0004] (2) The heat transfer coefficient is small and the efficiency is low
After a lot of research and improvement, although the heat transfer coefficient of the shell and tube heat exchanger has been improved, it is at the cost of increasing the pressure loss, and the overall efficiency is still very low.
[0005] (3) Poor reliability
Tube bundle vibrations are likely to occur at high flow rates, causing tube ruptures, damage to equipment foundatio

Example Embodiment

[0028] Hereinafter, the present invention will be further described in detail with reference to the accompanying drawings and embodiments, but the embodiments of the present invention are not limited thereto.

[0029] As shown in Figure 1, an exchanger with a honeycomb structure includes a shell 10 and a tube bundle. The shell 10 is provided with a fluid inlet 2 and a fluid outlet 9, and two ends of the shell 10 are respectively provided with a tube box 8 and a tube box. 8 is provided with a tube bundle fluid inlet 7 and an outlet 1, and the housing 10 has a regular hexagonal cross-sectional shape. The tube bundle is composed of a plurality of short honeycomb tube bundles 3 and long honeycomb tube bundles 4 to form a honeycomb tube bundle core 12, and the gap between the outer edge of the honeycomb tube bundle core 12 and the housing 10 is less than 3 mm. The two ends of the long honeycomb tube bundle 4 are respectively communicated with the inlet 7 and the outlet 1 in the tube bo...

Abstract

The invention discloses an exchanger with honeycomb structure, wherein, its frame (10) is in regular hexagon shape; the tube beam has several short honeycomb tubes (3) and long honeycomb tubes (4) to form honeycomb tube element (1), while the long honeycomb tubes (4) are adjacent with the short ones (3) with shared walls; the thickness of the wall of long and short tubes (4, 3) is 0.2-2mm; two ends of long honeycomb tube (4) are through to the inlet (7) and the outlet (1) of tube box (8). The invention has large unit heat exchange area, compact structure, high factor K, and high flexibility.

Description

technical field [0001] The invention relates to a shell-and-tube heat exchanger in energy technology, in particular to an exchanger with a honeycomb structure. Background technique [0002] Heat exchanger is a general process equipment widely used in power, metallurgy, refrigeration, oil refining, chemical industry, aviation, atomic energy, medicine and other industrial sectors. With the increasingly prominent energy problems, it is required to reduce the volume of the equipment as much as possible under the premise of satisfying the heat exchange, that is, to improve the compactness of the equipment, thereby reducing the weight of the equipment, saving materials, and correspondingly reducing the occupied area. As a result, high-efficiency heat exchangers came into being. In some application fields, there are special requirements for the size and weight of heat exchange equipment. Therefore, ultra-compact heat exchangers with small volume and large heat exchange area per un...
