Description

Technical Field

[0001] The invention relates to the technical field of heat exchangers, and in particular to a composite heat exchanger structure based on a spiral plate. Background Art

[0002] A spiral heat exchanger is a highly efficient and energy-saving heat exchange device composed of a spiral plate or a spiral tube bundle. Heat transfer is achieved through the countercurrent flow of cold and hot fluids in the spiral channel. Its unique spiral structure enhances the turbulence effect, reduces dead zones and improves heat transfer efficiency. It is widely used in chemical, petrochemical, HVAC, food and medicine, environmental protection and other fields. However, existing spiral heat exchangers have many defects.

[0003] Existing spiral heat exchangers generally have the problem of non-detachable structure. Traditional welding process requires overall replacement when local damage occurs, which has high maintenance cost. The heat exchange channels with fixed spacing cannot adapt to thermal expansion and deformation, which can easily lead to stress concentration and even structural failure. The fluid can easily form flow dead zones in the spiral channels, resulting in low heat exchange efficiency and the risk of local overheating. Traditional flow guide devices are difficult to dynamically adjust the turbulence intensity according to the fluid characteristics, affecting the uniformity of heat exchange.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Please refer to the attached Figure 1 -Attached Fig.15The embodiment of the present invention provides a composite heat exchanger structure based on a spiral plate, including an external shell 1, a spiral plate 2 is arranged inside the external shell 1, the spiral plate 2 is fan-shaped, and a plurality of spiral plates 2 together form a heat exchange channel 3, a quick-connect assembly 4 is arranged between adjacent spiral plates 2, a thread groove 5 and a spherical groove 6 are provided on the outer surface of the spiral plate 2, the center points of the thread groove 5 and the spherical groove 6 are on the same horizontal line, a distance column 7 is connected to the inner thread of the thread groove 5, a groove 8 is provided at one end of the distance column 7 away from the thread groove 5, a spring 9 is arranged inside the groove 8, the top end of the distance column 7 is fixedly connected to a limiting ring 22, and the upper end of the outer surface of the distance column 7 is slidably connected to a spherical groove The spherical head 10 is provided with a spring 9 between the distance column 7 and the spherical head 10, and the limit ring 22 slides inside the spherical head 10. The size of the spherical head 10 is adapted to the size of the spherical groove 6. One end of the spiral plate 2 is connected with a high-heat feed pipe 11, and the two sides of the heat exchange channel 3 surrounded by multiple spiral plates 2 are respectively connected with a high-heat discharge pipe 12 and a heat exchange feed pipe 13. The outer surface of the external shell 1 is connected with a heat exchange discharge pipe 14, and the high-heat feed pipe 11 passes through the external shell 1 and is connected with a guide component 15. An adjusting component 16 is arranged inside the guide component 15. A heat dissipation component 17 is arranged on the outer surface of the external shell 1, and a closed door 21 is connected to the side surface flange of the external shell 1.

[0037] In this embodiment, the external shell 1 serves as a supporting body and provides an installation position for related components. The internal fan-shaped spiral plate 2 can be quickly disassembled and connected through a quick-connect assembly 4 to form a spiral heat exchange channel 3, and then the closed door 21 is closed to start working; the adjacent spiral plates 2 in the external shell 1 are telescopically connected through the coordination of the distance columns 7, the springs 9 and the spherical heads 10 to achieve the effect of adjustable spacing of the spiral plates 2, and this design avoids welding, allowing the distance columns 7 to be slightly elastically displaced under fluid impact, thereby reducing the risk of falling off due to stress concentration. The elastic structure of the spring 9 and the spherical head 10 ensures both assembly stability and thermal expansion compensation. The high-temperature fluid enters the flow guide component 15 from the diversion component 18, and generates pre-swirl under the action of the flow guide component 15. In addition, the amplitude of the pre-swirl can be adjusted by the component 16 to adapt to different fluid characteristics. Then, the high-temperature fluid is fully in contact with the heat exchange fluid flowing in the reverse direction in the spiral channel, and the fluid after heat exchange is discharged from the high-temperature discharge pipe 12 and the heat exchange discharge pipe 14 respectively. After one heat exchange is completed, the heat dissipation component 17 outside the external shell 1 can accelerate the dissipation of residual heat.

[0038] Please refer to the attached Figure 4 and attached Figure 5The quick-connect assembly 4 includes a quick connector 1 401 and a quick connector 2 402. The quick connector 1 401 and the quick connector 2 402 are fixedly connected at one end of the adjacent spiral plate 2. A slide groove 403 is provided inside the quick connector 1 401. A sliding block 404 is fixedly connected to the outer surface of the quick connector 2 402. The sliding block 404 is adapted to the slide groove 403. A gasket 405 is slidably connected to the outer surface of the quick connector 2 402.

[0039] In this embodiment, the quick-connect assembly 4 realizes the rapid disassembly and assembly of adjacent spiral plates 2 through the cooperation of quick connector 1 401 and quick connector 2 402. Specifically, the sliding block 404 is slid into the side of the slide groove 403, and a gasket 405 is sleeved between the quick connector 1 401 and the quick connector 2 402 to form a sealing layer. Through this connection method, when a section of the spiral plate 2 is damaged, it can be replaced separately without disassembling the heat exchanger as a whole. At the same time, it is convenient to regularly clean the scale in the channel, which solves the problem of difficult maintenance of traditional welded spiral plates 2.

[0040] Please see attached Fig.11 and attached Fig.12 The flow guide component 15 includes a connecting pipe 1501, one end of which is flange-connected to one end of the high-temperature feed pipe 11, and the two ends of the interior of the connecting pipe 1501 are fixedly connected to connecting rods 1502. The connecting pipe 1501 is fixedly connected to a turntable 1503 through multiple connecting rods 1502. A rotating shaft 1504 is rotatably connected between the two turntables 1503, and a fan blade 1505 is rotatably connected to the outer surface of the rotating shaft 1504. The other end of the connecting pipe 1501 is flange-connected to the diversion component 18.

[0041] In this embodiment, the connecting pipe 1501 serves as a connecting channel to connect the high-temperature feed pipe 11 with the diversion component 18, and the connecting rods 1502 at both ends thereof are used to fix the turntable 1503 to form a rotating support structure with the rotating shaft 1504 and the fan blades 1505; when the high-temperature fluid enters the connecting pipe 1501, the fan blades 1505 rotate autonomously under the impact of the fluid, and the rotation of the fan blades 1505 generates a pre-swirl flow, so that the fluid forms a spiral motion before entering the heat exchange channel 3. This rotating flow can enhance the degree of turbulence, destroy the boundary layer, and increase the utilization rate of the heat exchange area; at the same time, the pre-swirl flow design reduces the flow dead zone, avoids local overheating, and solves the problems of uneven fluid distribution and insufficient turbulence in traditional heat exchangers.

[0042] Please see attached Fig.13The adjustment component 16 includes an adjustment groove 1601, and multiple adjustment grooves 1601 are opened at both ends of the inside of the connecting tube 1501. A movable groove 23 is opened between the multiple adjustment grooves 1601, and the movable groove 23 is located directly below the connecting tube 1501. The adjustment groove 1601 is located between the connecting rod 1502 and the fan blade 1505. A pulley 1602 is slidably connected inside the adjustment groove 1601, and an adjustment rod 1603 is arranged between the two pulleys 1602. The adjustment rod 1603 passes through and is fixedly connected to the inside of the fan blade 1505, and the pulley 1602 is rotatably connected to both ends of the adjustment rod 1603.

[0043] In this embodiment, since different fluids require different pre-swirl intensities, when the pre-swirl intensity needs to be adjusted, the fan blade 1505 is manually pushed to push the pulley 1602 to the bottom of the connecting tube 1501, and then the pulley 1602 is rotated to slide laterally along the movable groove 23 to a suitable adjustment groove 1601. The position of the pulley 1602 changes, and the position of the adjustment rod 1603 fixedly connected thereto changes accordingly, and then the deflection angle of the fan blade 1505 changes. This operation is repeated until all the fan blades 1505 are adjusted to a suitable angle, thereby achieving the effect of adjusting the pre-swirl intensity. This component realizes manual optimization of the angle of the fan blade 1505 according to the fluid properties such as viscosity and flow rate, so that the pre-swirl intensity matches the fluid characteristics, which not only avoids the increase in energy consumption caused by excessive turbulence, but also prevents the reduction in heat exchange efficiency caused by laminar flow, so that the heat exchanger can adapt to the operation requirements of multiple working conditions and solves the problem of poor adaptability of traditional fixed-angle guide devices.

[0044] Please refer to the attached Fig.14 The diversion component 18 includes a connecting block 1801, which is flange-connected to the other end of the connecting pipe 1501. A plurality of diversion grooves 1802 are provided inside the connecting block 1801. The connecting block 1801 is connected to a plurality of feed branch pipes 1803 through the diversion grooves 1802. A regulating valve 1804 is rotatably connected inside the diversion groove 1802. A rotating rod 1805 is fixedly connected to the outer surface of the regulating valve 1804. One end of the rotating rod 1805 passes through the connecting block 1801 and is fixedly connected to an adjusting knob 1806.

[0045] In this embodiment, when multiple different fluids enter, they enter from different feed branch pipes 1803 respectively. When the flow needs to be adjusted, the adjusting knob 1806 is rotated to drive the rotating rod 1805 to rotate, and the regulating valve 1804 rotates accordingly to change the flow area, thereby independently controlling the flow of each feed branch pipe 1803, allowing multiple high-temperature fluids to be connected at the same time. By adjusting the flow ratio of each branch pipe, mixed heat exchange is achieved, so that the heat exchanger can adapt to complex working conditions and solve the problems of single fluid type and extensive flow control in traditional single-inlet heat exchangers.

[0046] Please refer to the attached Fig.15The heat dissipation assembly 17 includes a heat dissipation frame 1701, which is fixedly connected to the outer surface of the external shell 1. The heat dissipation frame 1701 is honeycomb-shaped and hollow inside. A heat pipe 1702 is fixedly connected to the gap of the heat dissipation frame 1701, and a heat dissipation pipe 1703 is connected to the outer surface of the heat dissipation frame 1701.

[0047] In this embodiment, the heat dissipation frame 1701 is fixed on the outer surface of the external shell 1, and its honeycomb structure increases the heat dissipation area of ​​the device itself. Its internal hollow design allows natural air convection and the introduction of coolant to enhance heat dissipation. A heat pipe 1702 is also connected to the structural gap to transfer heat. The heat dissipation frame 1701 uses the phase change heat conduction principle to quickly conduct the waste heat inside the heat exchanger to the frame surface, and is connected to the outside with a heat pipe 1703, which can be connected to an external cooling system to form a circulating heat dissipation. This component effectively reduces the overall temperature of the heat exchanger by increasing the heat dissipation area, enhancing thermal conductivity and multi-mode heat dissipation, thereby ensuring the stability of the equipment during continuous operation.

[0048] Please refer to the attached Fig.15 The interior of the heat dissipation frame 1701 is fixedly connected with heat dissipation fins 1704 , and the heat dissipation fins 1704 are evenly distributed inside the heat dissipation frame 1701 .

[0049] In this embodiment, the evenly distributed heat dissipation fins 1704 further increase the area of ​​natural air convection and accelerate the heat dissipation efficiency of the heat dissipation frame 1701.

[0050] Please refer to the attached Figure 6 The outer surface of the spiral plate 2 is fixedly connected with heat dissipation fins 201 , and the heat dissipation fins 201 are evenly distributed on the outer surface of the spiral plate 2 .

[0051] In this embodiment, the evenly distributed heat dissipation fins 201 increase the contact area between the cold and hot fluids and improve the heat exchange efficiency of the heat exchange pipe.

[0052] Please refer to the attached Figure 1 A placing pier 19 is fixedly connected to the outer surface of the external shell 1. Above the placing pier 19, a moving ring 20 is fixedly connected to the outer surface of the external shell 1. The placing pier 19 and the moving ring 20 are located in the gap of the heat dissipation frame 1701.

[0053] In this embodiment, the placement pier 19 outside the external shell 1 is convenient for placing the equipment in a fixed working area, and the moving ring 20 is convenient for hoisting the moving equipment.

[0054] Please refer to the attached Fig. 9 and attached Fig.10 One end of the spring 9 abuts against the inner wall of the groove 8 , and the other end of the spring 9 is fixedly connected to the inner wall of the spherical head 10 .

[0055] In this embodiment, one end of the spring 9 is fixed against the other end, so as to avoid accidental breakage of the spring 9 due to inconsistent rotation speeds of the distance column 7 and the spherical head 10 when the distance column 7 is rotated.

[0056] Working principle: In actual use, firstly, the distance column 7 is threadedly connected to the outer surface of the spiral plate 2. Due to the action of the limit ring 22 at the top of the distance column 7, the spring 9 and the spherical head 10 are fixed together. Then, the multiple spiral plates 2 are spliced ​​outward along the center point of the external shell 1 in pairs by using the quick connection assembly 4. Specifically, the quick connector 2 402 outside the spiral plate 2 on one side is slid into the slide groove 4 of the quick connector 1 401 outside the spiral plate 2 on the other side by sliding the sliding block 404 of its protruding part. 03, the sliding direction is from the outside to the inside of the external shell 1. In the process of continuous splicing, the spiral plate 2 presses the spherical head 10 to compress the spring 9, and then the spiral plate 2 slides on the outer surface of the spherical head 10 until one end of the spiral plate 2 contacts the inner wall of the external shell 1. At this time, the spherical groove 6 on the spiral plate 2 coincides with the position of the spherical head 10, and the spring 9 rebounds to bounce the spherical head 10 into the spherical groove 6. This operation is repeated until the inside of the external shell 1 is filled, and then the closed door 21 is closed.

[0057] After the equipment is assembled, it can be used. If there is only one high-temperature fluid, the high-temperature fluid will be passed into any feed branch pipe 1803; if there are multiple high-temperature fluids, they will be passed into different feed branches 1803 at the same time. The high-temperature fluid enters the diversion slot 1802 through the feed branch pipe 1803. At this time, the adjusting knob 1806 can be rotated to control the opening and closing degree of the regulating valve 1804 and thus control the flow rate of the high-temperature fluid; the high-temperature fluid enters the flow guide component 15 after passing through the diversion component 18, and the fan blades 1505 inside it rotate under the drive of the high-temperature fluid. The pre-swirl is generated by rotating the fan blades 1505 to enhance the turbulence. In addition, for different types of high-temperature fluids, the fan blades 1505 can also play a role in stirring and mixing; because different types of high-temperature fluids require different degrees of turbulence, the fan blades 1505 can be manually rotated to move the pulley 1602 to the bottom of the connecting pipe 1501 before heat exchange, and then the pulley 1602 is rotated through the movable slot 23 Slide into the appropriate adjustment groove 1601, and at the same time, under the action of the adjustment rod 1603 connected to it, drive the fan blade 1505 to deflect to a suitable angle, thereby generating a suitable pre-swirl; after the high-temperature fluid passes through the guide component 15, it enters the high-temperature feed pipe 11, and then enters the heat exchange channel 3 surrounded by multiple spiral plates 2. At this time, the fluid to be heat exchanged is simultaneously introduced into the heat exchange feed pipe 13. Under the action of the spiral plate 2, the cold and hot fluids flow in reverse along the spiral channel for heat exchange. At the same time, the outer surface of the spiral plate 2 is evenly distributed with heat dissipation fins 201, which further increase the contact area of ​​the cold and hot fluids and improve the heat exchange efficiency. After the heat exchange is completed, the high-temperature fluid and the fluid to be heat exchanged flow out from the high-temperature discharge pipe 12 and the heat exchange discharge pipe 14 respectively.

[0058] On the other hand, after the equipment has undergone one heat exchange, its natural heat dissipation can be accelerated through the heat dissipation frame 1701 outside the external shell 1 to prepare for the next heat dissipation. Since the heat dissipation frame 1701 has a honeycomb structure and is hollow inside, and there are evenly distributed heat dissipation fins 1704 inside, the coolant can also be passed into the interior to further accelerate the heat dissipation; if part of the spiral plate 2 is damaged or needs to be cleaned during the heat exchange project, the closed door 21 will be opened to find the spiral plate 2 that needs to be replaced or cleaned, and then hold its outermost spherical head 10 and the distance column 7 connected to it, rotate the distance column 7, so that the distance column 7 is separated from the spiral plate 2 and then taken out, repeat this operation, take out all the distance columns 7 around the spiral plate 2 that needs to be replaced or cleaned, and then directly pull out the spiral plate 2 that needs to be replaced or cleaned, and then replace the new spiral plate 2 and repeat the assembly process.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
