Description

Technical Field

[0001] The invention relates to the technical field of heat exchange equipment, and in particular to a magnetic fluid enhanced spiral nested tube radiator. Background Art

[0002] In the field of industrial heat exchange, traditional equipment such as shell-and-tube and plate-type equipment relies on increasing flow rate or expanding surface area to enhance heat transfer, but this is accompanied by a sharp increase in energy consumption and a waste of space. Especially for cross-flow piping systems, laminar boundary layer resistance leads to low heat transfer efficiency on the pipe wall. Although turbulence can be increased by inserting turbulators or surface treatment (such as micro-fin tubes), there are disadvantages such as increased pressure loss and easy scaling and clogging. Although magnetic nanofluid technology is used to enhance thermal conductivity, particles tend to agglomerate and settle under passive flow, making it difficult to continuously disrupt the boundary layer.

[0003] High-power density devices (such as data center servers and power electronics cooling systems) require heat sinks to dissipate high heat flux densities within a very small space. Traditional straight-tube heat sinks often require a large footprint to meet these requirements, while compact microchannels face challenges such as complex processing, clogging, and weak pressure tolerances. While spiral tube structures can improve heat transfer by extending the flow path, a single spiral tube has high flow resistance and lacks flexible integration with the main pipeline.

[0004] Most existing heat exchangers feature fixed flow paths, making them incapable of responding to dynamic operating conditions. For example, excessive heat dissipation during low server loads wastes pump power, while insufficient heat dissipation occurs during sudden heat loads. While variable-frequency pumps can adjust flow rates, they cannot alter the flow path structure or local heat exchange intensity, limiting energy efficiency optimization.

[0005] In air-cooled radiators, air-side thermal resistance accounts for over 70% of the total thermal resistance. Traditional finned tubes rely on increasing fin area or forced ventilation, but the airflow is mostly unidirectional, laminar, with a thick boundary layer and a short flow path. While adding fans to increase air speeds can significantly increase noise and energy consumption, achieving uniform turbulence is difficult, and a "dead zone" easily forms in the center.

[0006] Scaling (on the liquid side) and dust accumulation (on the air side) of heat exchangers are the primary causes of performance degradation. Chemical cleaning or mechanical descaling require downtime and disassembly, impacting system continuity. Dust screens are often simple, covering the entire heat dissipation module, requiring complete disassembly for dust removal, resulting in high maintenance costs.

[0007] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] The present invention enhances heat exchange through magnetic fluid. Specifically, a rotating mesh cylinder and magnetic nanoparticles driven by a three-phase rotating magnetic field are arranged in a cross-flow pipe. The rotating magnetic field drives the nanoparticles to vigorously stir the fluid, destroying the laminar boundary layer near the pipe wall, enhancing turbulence, and greatly enhancing the heat transfer efficiency inside the fluid and between the fluid and the pipe wall; the continuous rotation and stirring of the particles helps to flush the pipe wall, reduce or delay the deposition of scale, and maintain long-term and efficient heat dissipation performance; by adjusting the power supply module (controlling the magnetic field strength and rotation speed), the stirring intensity can be controlled in real time and accurately to adapt to different heat load requirements.

[0034] The present invention adopts a spiral sleeve embedded structure, specifically, multiple groups of spiral sleeves are embedded between the upper and lower cross-flow pipes, which are connected by an electronic three-way valve. The spiral structure greatly extends the effective heat dissipation length of the fluid flow within a limited space, achieving a compactness that cannot be matched by traditional straight tube radiators; when the fluid flows in the spiral tube, centrifugal force is generated, inducing secondary vortexes, further destroying the boundary layer and promoting fluid mixing, and further improving the convective heat transfer effect; because the spiral tube itself has a larger surface area than a straight tube with the same projected area, the heat exchange area with the outside world (air / heat dissipation structure) is directly increased.

[0035] The present invention can realize intelligent flow path control. The specific implementation method is to set electronic three-way valves in the upper and lower pipe joints connecting the spiral sleeve. By controlling the opening and closing combination of each three-way valve, the flow path of the fluid between the cross-flow pipe and the spiral sleeve can be flexibly changed (for example: all flowing through the spiral tube, partially bypassing, changing the series / parallel combination, etc.) and direction, thereby dynamically optimizing the distribution and flow of the fluid according to real-time heat dissipation needs, fluid flow, inlet temperature and other factors, thereby realizing on-demand adjustment of radiator performance and energy efficiency optimization.

[0036] The present invention incorporates a highly efficient airflow organization and heat dissipation structure, specifically a multi-stage composite heat dissipation structure consisting of heat-conducting fins, a deflecting plate (at a 45-degree angle), a heat-conducting plate (with serpentine heat outlets), and heat-dissipating fins. The heat-conducting fins, which directly contact the cross-flow pipe, rapidly transfer heat from the pipe to the heat dissipation area. The deflecting plate forcibly converts the vertical incoming air into a counterflow parallel to the spiral sleeve. Crucially, these counterflows collide in the central region of the radiator, generating intense turbulence and disturbance, which significantly disrupts the thermal boundary layer on the air side and significantly improves the heat exchange efficiency on the air side. After the collision, the airflow changes direction, which increases the residence time and flow in the radiator; the serpentine heat dissipation port can guide the airflow after the collision to pass through the guide heat dissipation plate in an orderly manner, increasing the flow and disturbance; the heat dissipation fins serve as the final heat dissipation surface, collecting the airflow for efficient heat dissipation, and the fin layout on the inside of the frame makes full use of the space; this carefully designed "vertical air intake → deflected into counter-flow → middle collision → change of direction → passing through the serpentine port → fin heat dissipation" airflow path maximizes the heat exchange efficiency between the air and the heat dissipation structure through multiple disturbances, diversions and flow extensions.

[0037] This system utilizes a modular and maintainable design, including a symmetrical frame and beam structure and a removable dust screen. The C-shaped frame, upper and lower beams, and welded connections provide excellent structural strength and rigidity. The removable dust screen effectively blocks dust and is easily removed for cleaning, ensuring long-term heat dissipation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] A deflection plate 21 is welded between two adjacent heat-conducting fins 20 , and the deflection plate 21 is tilted at 45°.

[0064] Three upper pipe joints 22 at equal intervals are welded to the lower end of the upper cross-flow pipe 13 , and three lower pipe joints 23 at equal intervals are welded to the upper end of the lower cross-flow pipe 13 .

[0065] The upper pipe joint 22 and the lower pipe joint 23 are arranged opposite to each other in the upper and lower directions. A spiral sleeve 24 is provided between the upper and lower pipe joints 22 and 23. Two adapter elbows 25 are welded to the upper and lower ends of the spiral sleeve 24 respectively. One of the adapter elbows 25 is fixedly connected to the upper pipe joint 22, and the other adapter elbow 25 is fixedly connected to the lower pipe joint 23.

[0067] A flow-guiding heat-dissipating plate 27 is provided on the left and right sides of each spiral sleeve 24 , and both ends of each flow-guiding heat-dissipating plate 27 are respectively clamped on the outer peripheral walls of the two cross-flow pipes 13 .

[0068] A serpentine heat dissipation opening 28 is formed on the side wall of each of the heat dissipation guide plates 27 .

[0069] A plurality of vertically extending heat dissipation fins 29 are welded to the middle portion of the inner side wall of the left frame plate 1 , and the plurality of heat dissipation fins 29 are arranged at equal intervals.

[0070] A heat dissipation fin 29 is also welded to the middle portion of the inner side wall of the right frame plate 2 .

[0071] like Figure 9 In the second embodiment shown, restraint buckles 30 are provided on the front and rear end surfaces of the left frame plate 1 and the right frame plate 2 , and a detachable dustproof screen plate 31 is mounted inside the restraint buckles 30 .

[0072] When the present invention is in use, first, according to the actual heat dissipation requirements, the circulating water pipeline is connected to the upper water inlet pipe 7, the lower water inlet pipe 8, the upper water outlet pipe 11 and the lower water outlet pipe 12 respectively. Hot water first enters the water inlet tank 5 and then flows into the cross-flow pipe 13. The power supply module 16 is started to power the electromagnetic generator 14, and its internal three-phase winding 15 generates a rotating magnetic field, driving the rotating mesh cylinder 17 and magnetic nanoparticles 18 in the cross-flow pipe 13 to rotate. This stirring effect causes the hot water to form a vortex in the cross-flow pipe 13, accelerating its heat exchange with the pipe wall. At the same time, the heat-conducting fins 20 in contact with the cross-flow pipe 13 conduct heat away.

[0073] Open the electronic three-way valve 26, introduce hot water into the upper pipe joint 22, and then flow into the spiral sleeve 24 through the adapter elbow 25. The hot water flows in a spiral in the spiral sleeve 24. This design greatly increases the effective heat dissipation length of the pipeline and significantly reduces the overall volume of the radiator. In addition, the centrifugal force generated by the spiral flow induces secondary mixing, promotes fluid mixing and destroys the boundary layer, thereby significantly improving the convective heat transfer coefficient. The hot water flowing through the spiral sleeve 24 then flows back to the cross-flow pipe 13 through the adapter elbow 25 and the lower pipe joint 23. By switching the opening and closing states of different electronic three-way valves 26, the flow path and direction of the hot water in the cross-flow pipe 13 and the spiral sleeve 24 can be changed to adapt to diverse heat dissipation needs.

[0074] As hot water flows through spiral sleeve 24, its heat dissipates through the tube walls and exchanges heat with the outside environment via deflector and heat sink 27. During the heat dissipation process, a fan blows vertically into the radiator. Some of this cool air directly carries away the dissipated heat; the remaining air is diverted by deflector plate 21 and converted into an opposing airflow parallel to spiral sleeve 24. This opposing airflow collides in the middle of the pipe, changes direction again, passes through serpentine heat dissipation vents 28 on deflector and heat sink 27, and converges at heat sink fins 29 for efficient heat dissipation.

[0075] Finally, the hot water after heat dissipation flows into the water outlet tank 9 for recovery.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein, and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and description of the present invention.
