specific Embodiment approach 1

[0015] Specific implementation mode one: combine Figure 1-Figure 4 To illustrate this embodiment, the asymmetric scaling type horizontal groove tube heat exchanger of this embodiment includes a shell 1, a cold medium inlet pipe 2, a cold medium outlet pipe 3, a heat medium inlet pipe 4, a heat medium outlet pipe 5, two A tube sheet 6, a first head 7, a second head 10, a horizontal partition 11, a plurality of baffles 8 and a plurality of heat exchange tubes 9, and a tube sheet 6 is installed on the inner walls of both ends of the shell 1, A first sealing head 7 is installed on one end surface of the casing 1, a second sealing head 10 is installed on the other side end surface of the casing 1, a heat medium inlet pipe 4 is arranged on the top of the casing 1, and a heat medium inlet pipe 4 is arranged on the bottom of the casing 1. The medium outlet pipe 5, the first head 7 is provided with a horizontal partition 11, the top of the first head 7 is provided with a cold medium i...

specific Embodiment approach 2

[0017] Specific implementation mode two: combination Figure 1-Figure 3 This embodiment will be described. The asymmetric zoom-type transverse groove pipe of this embodiment is made of carbon steel or alloy steel. Such setting is convenient for processing and forming, and has low cost and long service life. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0018] Specific implementation mode three: combination figure 2 with image 3 To illustrate this embodiment, the length P of the light pipe segment between two adjacent annular grooves on the asymmetric zoom-type transverse groove pipe of this embodiment is 5 mm to 15 mm. With this setting, the length of the bare pipe section is moderate, and the number of annular grooves is suitable, the cost of rolling the pipe by the machine tool is relatively low, and it is also conducive to the increase of the comprehensive heat transfer efficiency of the pipe pass. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention relates to a transverse slot pipe heat exchanger, in particular to an asymmetric retractable transverse slot pipe heat exchanger, which belongs to the technical field of heat exchanging process equipment and aims at solving the problems of low comprehensive heat transfer efficiency and being inapplicable to gas-steam heat exchanging in the existing transverse slot pipe heat exchanger. Each heat exchanging pipe is an asymmetric retractable transverse slot pipe; the curvature radius of an arc surface of the inside wall of the asymmetric retractable transverse slot pipe located at a flowing away side is less than that of an arc surface of the inside wall of the asymmetric retractable transverse slot pipe located at an incoming flow side; the width of an opening of a ringlike slot arranged on the asymmetric retractable transverse slot pipe is at a range of 6-10mm; the height of a bead of the ringlike slot arranged on the asymmetric retractable transverse slot pipe is at a range of 0.6-1.1mm; and the wall thickness of the asymmetric retractable transverse slot is at a range of 2-3mm. The transverse slot pipe heat exchanger provided by the invention is applicable to the industrial field, and is particularly applicable to the gas-steam heat exchanging.

Description

technical field [0001] The invention relates to a horizontal groove tube heat exchanger, in particular to an asymmetric zoom type horizontal groove tube heat exchanger, which belongs to the technical field of heat exchange process equipment. Background technique [0002] Since the energy crisis broke out in the 1970s, energy consumption has also increased, and research on the strengthening of traditional heat exchanger equipment has gradually emerged. The enhanced heat transfer of heat exchangers is to make the heat exchanger transfer heat per unit time and unit heat transfer area. The purpose of applying enhanced heat transfer technology is to try to transfer the specified heat with the most economical (small size, light weight, low cost) heat exchanger, which requires the developed heat exchanger to be as large as possible. Save money, energy and reduce metal consumption and space. At present, the research on shell-and-tube heat exchangers mainly focuses on two aspects: o...
