Description
P100570LU00 1 PORTABLE HEAT EXCHANGE DEVICE HAVING ARRAYED "9799
BACKGROUND Technical Field The present invention relates to the field of heat exchange device design technologies, and particularly, to a portable heat exchange device having arrayed planar elastic vortex tubes. Related Art A heat exchange device is an energy-efficient device that transfers heat between two or more fluids having different temperatures, to transfer heat of a fluid having a higher temperature to a fluid having a lower temperature, so that the temperatures of the fluids reach an indicator specified in a process, to meet the need of technological conditions, is | also a major device that improves the energy utilization, and is widely applied to the industrial fields of petroleum, chemical engineering, electric power, refrigeration, and the like.
The internal heat exchange element of a conventional shell-and-tube heat exchange device is made of a plurality of stainless steel straight tubes, and has a relatively large overall structure and low flexibility of assembly. The internal heat exchange element of a conventional tube-in-tube heat exchange device is made of a single stainless steel straight tube, and has a simple structure and low heat exchange efficiency. Since vibrations of a heat transfer element inside a flow-induced heat exchange device may cause fatigue damage, the method of preventing vibrations and avoiding damage by increasing strength of rigid tube bundles is not always effective. An elastic tube bundle heat exchange device has conventional rigid elements (stainless steel tubes) replaced with elastic heat transfer elements (red copper tubes), fully uses vibrations of a flow-induced elastic heat transfer element to enhance heat transfer, and has obvious advantages in preventing damage to a tube bundle, reducing noise, and automatic descaling. However, due to limitations of the arrangement of an internal tube bundle and the overall size, a heat transfer enhancement effect of such an elastic tube bundle heat exchange device is not obvious, and the flexibility of combination and use of a plurality of such heat exchange devices is low. Based on the foregoing problems of the heat exchange device, requirements for high efficiency and flexibility cannot be met.

P100570LU00 2 SUMMARY LU102100 To overcome problems in actual engineering applications of existing tubular heat exchange devices, a portable heat exchange device having arrayed planar elastic vortex tubes is provided in the present invention.
The present invention is achieved through the following technical solution.
A portable heat exchange device having arrayed planar elastic vortex tubes is provided, including a left seal head, a right seal head, a tube-side outlet tube, a planar elastic vortex tube bundle, a left tube-sheet end cover, a right tube-sheet end cover, a tube sheet-fixing collar, a tube sheet-fixing frame, a mass block, a cylinder, flanges, gaskets, shell-side outlet and inlet tubes, a connecting tube, and a bracket. Planar elastic vortex tubes includes planar red copper vortex tubes that are arranged in an array and that are nested within each other. For the planar elastic vortex tube bundle, planar elastic vortex tubes are connected to the tube sheet-fixing frame in an evenly spaced manner through the tube sheet-fixing collar, and a mass block is connected between the groups of the planar elastic vortex tubes; the cylinder is fixedly connected between the left and right tube-sheet end covers, and the gaskets are disposed between the cylinder and the tube-sheet end covers; and the left and right seal heads are fixedly connected to the left and right tube-sheet end covers respectively, and the gaskets are disposed between the tube-sheet end covers and the seal heads. The heat exchange device may be individually used in time through a handle and the bracket, or a plurality of heat exchange devices may be combined, installed, and used as a one-row array by using the flanges disposed at inlets and outlets, the connecting tube, and the bracket.
In a preferred technical solution of the present invention, a group of planar elastic vortex tubes including a plurality of planar red copper vortex tubes is fixedly connected to the tube sheet. A plurality of groups of planar elastic vortex tubes form the planar elastic vortex tube bundle, and all the groups of the planar elastic vortex tubes are arranged in an evenly spaced manner between the tube sheet left and right end covers. The mass block is mounted between the groups of planar elastic vortex tubes.
In a preferred technical solution of the present invention, each group of planar elastic vortex tubes includes 4 planar red copper vortex tubes nested within each other, and an outer diameter remains unchanged, thereby saving space and improving the utilization. The whole heat exchange device has a proper size, and the portable heat exchange device having arrayed planar elastic vortex tubes can be directly and individually used through the
P100570LU00 3 handle and the bracket. HU102100 In a preferred technical solution of the present invention, the cylinder is fixed between the left and right tube-sheet end covers, the left and right seal heads are connected to the other ends of the left and right tube-sheet end covers, the flanges are connected to the seal heads, the flange is connected to the connecting tube, and the bracket is mounted at the flange, to implement combination, installation, and use of the heat exchange device.
During on-site use, a pressure test and an air-tight test need to be performed on the heat exchange device having arrayed planar elastic vortex tubes before installation. A path through which a hot medium flows in the tube-side inlet tube, the planar elastic vortex tube bundle, and the tube-side outlet tube is referred to as a tube side. A path through which a cold medium flows in the shell-side inlet tube, vortex tubes, and a gap between the outlet tube and the cylinder is referred to as a shell side. The heat exchange device having planar elastic vortex tubes is installed in a horizontal manner. When a plurality of portable heat exchange devices having elastic vortex tubes work, a tube-side hot medium flows in from the tube-side inlet and flows out from the tube-side outlet, and a shell-side cold medium flows in from a bottom shell-side inlet, to fill up the shell body, and then, flows out from a top shell-side outlet. Cross flowing of the shell-side medium and the tube-side medium is achieved, which is beneficial to achieving a better heat exchange effect. According to requirements under actual heat exchange conditions, a single heat exchange device can be directly and individually used by using the handle and the bracket, and a plurality of heat exchange devices may be combined and installed as a one-row array by fixedly connecting the flanges at inlets and outlets.
Compared with prior art, the beneficial effect of the present invention is that copper tubes are used in all tube bundles in the present invention. Copper material is an elastic material. Vibrations of planar red copper vortex tubes generated through induction of the shell-side and tube-side fluid media enhance a turbulence characteristic of a fluid medium near an outer wall insides the tube, thereby enhancing heat transfer. Vibrating copper tubes are unlikely to suffer fatigue damage, have features of noise reduction and automatic descaling, and can be used for a long term. The tube bundle is a vortex tube structure, and a secondary flow generated when the fluid medium inside the tube flows further enhances heat transfer. Under the action of the mass blocks, inherent characteristics of the tube bundle are changed, so that a vibration characteristic under the induction of the fluid is regulated, thereby further enhancing heat transfer through vibration. The heat exchange
P100570LU00 4 device having planar elastic vortex tubes is installed in a horizontal manner, so that 195100 pressure drops of inlets and outlets of vortex tubes tend to be consistent, helping to achieve a uniform and consistent vibration effect of rows of vortex tubes. The heat exchange device may be individually and directly used through the handle and the bracket installed on the single heat exchange device, and a plurality of heat exchange devices may be combined and installed as a one-row array by using the flanges disposed at inlets and outlets, and the connecting tube, and may be flexibly assembled and disassembled according to an actual situation.
