Embodiment 1

[0039] Example 1: A planar folded type elastically reinforced heat exchange tube bundle, the structure of which is as follows figure 1 shown, including:

[0040] A plurality of first heat exchange tubes 2;

[0041] The direction of the first heat exchange tube 2 is different and the second heat exchange tube 7 is in the same plane; both ends of each second heat exchange tube 7 are airtightly connected with the slider 4, and each slider 4 is at least It is airtightly connected with one first heat exchange tube 2 .

[0042] Wherein, the axes of any first heat exchange tube 2 and any second heat exchange tube 7 are perpendicular. And the first heat exchange tube 2 and the second heat exchange tube 7 are both straight tubes.

[0043] Meanwhile, there are at least two first heat exchange tubes 2 .

[0044] In all the first heat exchange tubes 2 , the ends not connected to the sliders 4 have mounting heads 3 .

[0045] The floating block 4 can have two structures, one is hollow...

Embodiment 2

[0049] Embodiment 2: a kind of heat exchanger, its structure is as figure 1 , image 3 and Figure 4 As shown, it has a shell 5, and the shell 5 has a fixed support 6 and a heat exchange tube bundle. The heat exchange tube bundle is the heat exchange tube bundle structure provided in Example 1, and the heat exchange tube bundle is arranged horizontally.

[0050] The principle of this embodiment is: the tube-side fluid enters from one installation head 3 , flows out from the other installation head 3 after passing through the first heat exchange tube 2 , the slider 4 and the second heat exchange tube 7 . The shell-side fluid flows in from the lower end of the heat exchanger shell 5 and flows out from the upper end. When the shell-side fluid flows around the horizontally arranged planar folded elastic tube bundle, the alternating lateral fluid force acting on the elastic tube bundle can cause the heat exchange tube bundle 1 to generate lateral vibration, thereby achieving the...

Embodiment 3

[0056] Embodiment 3: A kind of planar folding type elastic reinforced heat exchange tube bundle, its structure is as follows figure 2 shown, including:

[0057] Multiple heat exchange tubes 8;

[0058] The end of each heat exchange tube 8 is airtightly connected with a floating block 4 , and the end of the heat exchange tube 8 not connected with the floating block 4 has a mounting head 3 .

[0059] All the heat exchange tubes 8 are straight tubes, and there are at least two heat exchange tubes 8 . The axes of all the heat exchange tubes 8 are located in the same plane, so that the heat exchange tubes 8 and the sliders 4 form a heat exchange tube bundle 1 .

[0060] In this embodiment: the floating block 4 is hollow inside, and the two openings are located on the same surface.

[0061] Adopting the above-mentioned structure can make the heat exchange tube form a single-fold structure.

[0062] The heat exchange tube bundle in this embodiment is basically in a horizontal stat...

Abstract

The invention relates to a plane inflexion type elastic intensified heat exchange tube bundle and a heat exchanger, and belongs to the related field of heat exchange technologies. A heat exchange tube bundle part mainly comprises a plurality of first heat exchange tubes and second heat exchange tubes which are different from the first heat exchange tubes in direction and are located in the plane where the first heat exchange tubes are located; the two ends of any second heat exchange tube are in closed connection with one end of the corresponding first heat exchange tube through floating blocks; and the end, which is not connected with the corresponding second heat exchange tube, of each first heat exchange tube is in closed connection with the adjacent first heat exchange tube through a floating block. According to the plane inflexion type elastic intensified heat exchange tube bundle and the heat exchanger, by designing a brand new structure, shell side fluid can be sufficiently used for inducing transverse vibration for intensification of heat transfer, and the advantages of being small in transverse stiffness and large in unit volume heat exchange area are achieved.

Description

technical field [0001] The invention relates to the related field of heat exchange technology, in particular to a planar folding type elastic enhanced heat exchange tube bundle and a heat exchanger. Background technique [0002] The vibration of the heat transfer element in the heat exchanger can significantly improve the heat transfer effect. Within a certain range of vibration parameters, the heat transfer coefficient of the heat transfer element can be increased by as much as 9 times, and the vibration of the heat transfer element can inhibit the formation of surface dirt. Reduce fouling thermal resistance, and finally achieve compound enhanced heat transfer. [0003] In the prior art, there are already some relevant studies on the application of fluid-induced vibration enhanced heat transfer theory to heat exchanger engineering, such as: [0004] Chinese invention patents "floating coil two-stage heating steam-water heat exchanger" (application number: 92106727.5) and "...
