Description

Technical Field

[0001] This invention relates to the field of marine cooling system technology, and in particular to a self-flowing vibration-damping conformal cooler and conformal cooling system. Background Technology

[0002] Marine propulsion systems contain numerous seawater coolers. Traditional ships employ decentralized cooling technology, where seawater cooling zones are distributed throughout the engine room, with seawater supplied to the coolers via decentralized water supply pipes. This results in the following drawbacks: Firstly, the seawater cooling zones occupy a significant amount of cabin volume, reducing the ship's effective carrying capacity. Secondly, the piping system connecting the seawater coolers is prone to damage under the combined effects of long-term marine corrosion, erosion, and pressure, leading to leaks within the cabins and affecting the safety and reliability of the ship's navigation.

[0003] Therefore, new ships widely adopt central cooling technology, which uses a centralized cooler to cool fresh water, which then indirectly cools the original seawater cooler, thus reducing the seawater boundary and improving the reliability of ship operation. However, in a central cooling system, because the cooling load is discharged externally through the centralized cooler, the equipment is bulky and occupies cabin space. To address these issues, researchers have proposed an external conformal cooling technology, which increases the utilization rate of internal cabins by designing the centralized cooler conformally to the hull structure.

[0004] Existing conformal cooling technologies mostly employ shell-and-tube cooling, with thin-walled heat exchange tubes forming the heat exchange interface between the cold and hot media. During the operation of conformal cooling systems, the transverse scouring of the heat exchange tube bundle by seawater outside the tubes causes flow-induced vibration, which can lead to mechanical wear or fatigue damage over long-term operation. Furthermore, the heat exchange tubes have weak load-bearing capacity under external impacts in the marine environment, resulting in low reliability of conformal coolers and conformal cooling systems.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0029] The terms "first" and "second" in the specification and claims of this invention may explicitly or implicitly include one or more of those features. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0030] The following is combined with Figures 1-8 The present invention describes a self-flowing vibration-damping conformal cooler and conformal cooling system.

[0031] like Figure 1 and Figure 8 As shown, in an embodiment of the present invention, the self-flowing vibration-damping conformal cooler includes: a shell 100, a plurality of heat exchange tube bundles 10, and a flow guide 20. The shell 100 is the hull of a ship's stern fin, located behind the ship's propeller 600 along the ship's forward direction. The shell 100 contains a plurality of heat exchange tube bundles 10. A first liquid inlet 110 is provided on the side of the shell 100 facing the propeller 600, and a first liquid outlet 120 is provided on the side of the shell 100 opposite to the propeller 600. The flow guide 20 is disposed at the first liquid inlet 110, and the flow guide 20 can automatically adjust the diameter of the first liquid inlet 110 according to the magnitude of the impact force of the seawater it receives.

[0032] Specifically, the shell 100 of the self-flowing vibration-damping conformal cooler is the shell of a ship's tail fin. The cross-section of the ship's tail fin shell is airfoil-shaped. The first liquid inlet 110 is located at the leading edge of the ship's tail fin shell, and the first liquid outlet 120 is located at the trailing edge of the ship's tail fin shell. When the ship is moving, the thrust of the propeller 600 can be used to achieve self-supply of water to the first liquid inlet 110. At the same time, the pressure difference driven by the stagnation point at the leading edge and the flow separation effect at the trailing edge can be enhanced to achieve efficient self-flowing cooling.

[0033] Furthermore, the diverter 20 is located at the first liquid inlet 110. When the diverter 20 experiences a large impact force from the seawater, its outward expansion is greater, the diameter of the first liquid inlet 110 increases, the flow rate of seawater entering the shell 100 increases, and the impact force on the heat exchange tube bundle 10 also increases accordingly. Conversely, when the diverter 20 experiences a smaller impact force from the seawater, its outward expansion is smaller, the diameter of the first liquid inlet 110 is also smaller, and the flow rate of seawater entering the shell 100 is less, resulting in a smaller impact force on the heat exchange tube bundle 10. Moreover, the impact force of the seawater on the diverter 20 is positively correlated with the ship's speed. When the ship's speed is higher, the impact force on the diverter 20 is greater; conversely, when the ship's speed is lower, the impact force is less.

[0034] In this embodiment, by adjusting the ship's sailing speed, the diameter of the first liquid inlet 110 can be automatically adjusted. When the ship is running in a low-to-medium economic mode, the diameter of the first liquid inlet 110 becomes smaller, thereby reducing the flow rate of seawater entering the shell 100, thereby reducing the impact of seawater on the heat exchange tube bundle 10 and improving the service life of the heat exchange tube bundle 10.

[0035] The self-flowing vibration-damping conformal cooler provided in this embodiment of the invention reduces the flow rate of seawater entering the shell of the self-flowing vibration-damping conformal cooler by setting a flow guide at the first liquid inlet of the shell. The flow guide can automatically adjust the diameter of the first liquid inlet according to the ship's sailing speed, thereby reducing the impact of seawater on the heat exchange tube bundle, improving the impact resistance of the heat exchange tube bundle, and extending the service life of the heat exchange tube bundle.

[0036] like Figure 2 As shown, in an embodiment of the present invention, the diverter 20 includes a pair of diverting parts, which are disposed opposite to each other at the first liquid inlet 110. The length direction of each diverting part is consistent with the length direction of the housing 100. The first end of each diverting part along its own width direction is connected to the housing 100, and the second end of each diverting part along its own width direction is a free end. An expansion port is formed between the two diverting parts, which faces the propeller 600. The distance between the two diverting parts is the diameter of the first liquid inlet 110. The two free ends can move in opposite directions under the impact of seawater to change the size of the diameter.

[0037] Specifically, the expansion opening formed by the two drainage sections serves as the seawater inlet. When the distance between the two drainage sections is small, the diameter of the first inlet 110 is small, and vice versa. During ship movement, the seawater impacts the expansion opening formed by the two drainage sections, causing the second ends of the two drainage sections to move away from each other, thereby increasing the distance between the two drainage sections and the diameter of the first inlet 110, thus increasing the flow rate of seawater entering the hull 100.

[0038] Furthermore, such as Figure 2 and Figure 3As shown, in an embodiment of the present invention, each drainage section includes an elastic plate 21 and a flexible plate 22. The cross-sectional shape of the elastic plate 21 is arc-shaped, and the arcs of the two elastic plates 21 are arranged opposite each other to form an expansion opening between the two elastic plates 21. The flexible plate 22 is stacked with the elastic plate 21, and the shape of the flexible plate 22 matches the shape of the elastic plate 21. The first end of the flexible plate 22 along its own width direction and the first end of the elastic plate 21 along its own width direction are connected to the housing 100, and the second end of the flexible plate 22 along its own width direction and the second end of the elastic plate 21 along its own width direction are free ends. The flexible plate 22 has a plurality of elastic air-sealing holes 23. When the flexible plate 22 is impacted by seawater, the longitudinal cross-sectional dimension of the elastic air-sealing holes decreases, thereby increasing the diameter of the first liquid inlet 110.

[0039] Specifically, in this embodiment, the elastic plate 21 can be made of metal. The second end of each elastic plate 21 is bent towards one side of the elastic plate 21, making the cross-section of the entire elastic plate 21 arc-shaped. Two elastic plates 21 are arranged opposite each other at the first liquid inlet 110, and the arcs of the two elastic plates 21 are both facing the side wall of the housing 100, so that an expansion opening is formed between the two elastic plates 21. A flexible plate 22 is stacked on the elastic plate 21. The flexible plate 22 can be made of rubber or the like. The flexible plate 22 has a certain thickness and has multiple elastic air-sealing holes 23 inside. When seawater impacts the flexible plate 22, the elastic air-sealing holes 23 are deformed under pressure, making their longitudinal cross-sectional dimensions smaller, becoming elongated air holes, thereby reducing the thickness of the flexible plate 22, increasing the distance between the two flexible plates 22, and thus increasing the diameter of the first liquid inlet 110.

[0040] Specifically, when the ship travels at a high speed, the impact force of seawater on the flexible plate 22 is greater. At this time, the elastic air seal pore 23 deforms severely, and the distance between the two flexible plates 22 increases. When the impact force of seawater on the flexible plate 22 is greater than the elastic force of the elastic plate 21, the elastic plate 21 deforms, and the diameter of the first liquid inlet 110 further increases. Conversely, when the ship travels at a low speed, the impact force of seawater on the flexible plate 22 is smaller. At this time, the deformation of the elastic air seal pore 23 is smaller, and the diameter of the first liquid inlet 110 is also smaller. Therefore, the flow rate of seawater entering the shell 100 is less, and the impact force on the heat exchange tube bundle 10 is also less. Furthermore, when the ship's speed decreases or it stops traveling, when the impact force of seawater on the flexible plate 22 is less than the elastic force of the elastic plate 21, the second ends of the two flexible plates 22 move closer to each other, causing the diameter of the first liquid inlet 110 to decrease. When the ship is stationary, the diameter of the first liquid inlet 110 is at its minimum.

[0041] The self-flowing vibration-damping conformal cooler provided in this embodiment of the invention can automatically adjust the diameter of the first liquid inlet according to the ship's sailing speed by setting an elastic plate and a flexible plate at the first liquid inlet. When the ship is running in a low-to-medium economic mode, the diameter of the first liquid inlet can be automatically reduced to reduce the flow rate of seawater entering the shell, thereby reducing the impact of seawater on the heat exchange tube bundle.

[0042] like Figure 4 and Figure 6 As shown, in an embodiment of the present invention, the heat exchange tube bundle 10 includes multiple heat exchange tube structures and multiple spherical connectors 102. The multiple heat exchange tube structures are arranged sequentially along the length direction of the shell 100, and adjacent two heat exchange tube structures are connected by spherical connectors 102 to form a heat exchange tube bundle 10. Each heat exchange tube structure includes multiple heat exchange branch pipes 101, which are arranged in a ring and connected to a spherical connector 102.

[0043] Specifically, in this embodiment, each heat exchange tube bundle 10 consists of multiple heat exchange tube structures and multiple spherical connectors 102. Each heat exchange tube structure includes multiple heat exchange branch pipes 101, which are arranged in a ring. After passing through each heat exchange branch pipe 101, the fluid converges into a spherical connector 102, and then is diverted from the spherical connector 102 into the multiple heat exchange branch pipes 101 of the next heat exchange tube structure. This flow continues until the fluid flows out of the shell 100.

[0044] In this embodiment, as Figure 5 As shown, viewed from the side of the shell 100, each heat exchange tube bundle 10 is a cellular structure. Multiple heat exchange tube bundles 10 are arranged sequentially to form a compact cellular body. When seawater impacts the heat exchange tube bundles 10 laterally, the compactly arranged cellular body reduces the turbulent vibration caused by the seawater impact, thereby improving the impact resistance of the heat exchange tube bundles 10. At the same time, the periodic arrangement of multiple heat exchange tube bundles 10 can generate complex spatial turbulence, causing the seawater entering the shell 100 to scour the heat exchange tube bundles 10 laterally, longitudinally, and obliquely, effectively enhancing the heat exchange capacity of the vibration-damping conformal cooler.

[0045] Optionally, the pattern formed by the annular arrangement of multiple heat exchange branch pipes 101 can be hexagonal or octagonal, etc. It can be understood that the more heat exchange branch pipes 101 contained in each heat exchange tube structure, the higher the strength of each unit cell structure, and thus the higher the strength of the unit cell composed of multiple heat exchange tube bundles 10.

[0046] The self-flowing vibration-damping conformal cooler provided in this embodiment of the invention sets each heat exchange tube bundle as a heat exchange tube structure with multiple heat exchange branches arranged in a ring. After the multiple heat exchange tube bundles are arranged, they can form a tightly packed cell, thereby reducing the turbulent vibration caused by seawater impact on the heat exchange tube bundles and improving the impact resistance of the heat exchange tube bundles. At the same time, the periodic arrangement of multiple heat exchange tube bundles can generate complex spatial turbulence, causing the seawater entering the shell to scour the heat exchange tube bundles laterally, longitudinally and obliquely, effectively enhancing the heat exchange capacity of the conformal cooler.

[0047] Furthermore, such as Figure 4 and Figure 5 As shown, in an embodiment of the present invention, the side view shape of each heat exchanger tube structure is hexagonal. Specifically, in this embodiment, each heat exchanger tube structure includes six heat exchanger branch pipes 101, which are arranged in a ring to form a hexagon.

[0048] like Figure 6 As shown, in one embodiment of the present invention, each heat exchange branch pipe 101 includes a first pipe 1011, a second pipe 1012, and a third pipe 1013 connected in sequence. The second pipe 1012 is arranged parallel to the inner wall of the shell 100, the first pipe 1011 and the first end of the second pipe 1012 are inclined, and the third pipe 1013 and the second end of the second pipe 1012 are inclined. The first pipe 1011 and the third pipe 1013 are respectively connected to two adjacent spherical connectors 102.

[0049] Specifically, in this embodiment, the length of the second pipe 1012 should be as short as possible so that the shape formed by connecting the first pipe 1011, the second pipe 1012 and the third pipe 1013 is approximately a triangle, so as to form a stable short pipe triangular support structure and suppress the vibration of the heat exchange tube bundle 10 under seawater excitation.

[0050] like Figure 6 As shown, in an embodiment of the present invention, each heat exchange tube bundle 10 further includes a plurality of second liquid inlets 131 and a plurality of second liquid outlets 132. Each second liquid inlet 131 is connected to one end of a heat exchange tube bundle 10, and each second liquid outlet 132 is connected to the other end of a heat exchange tube bundle 10.

[0051] Specifically, the fluid flow within each heat exchanger tube bundle 10 is as follows: Figure 7 As shown, the high-temperature fluid entering the shell 100 enters multiple heat exchange branch pipes 101 of a heat exchange tube structure through the second inlet 131, and then converges into the spherical pipe 102, and then enters multiple heat exchange branch pipes 101 of the next heat exchange tube structure, flowing sequentially until it flows out from the second outlet 132.

[0052] like Figure 1As shown, in an embodiment of the present invention, the self-flowing vibration-damping conformal cooler further includes an inlet tube sheet 113 and an outlet tube sheet 123. The inlet tube sheet 113 and the outlet tube sheet 123 are respectively disposed at both ends of the housing 100. The inlet tube sheet 113 has multiple liquid inlet holes, each corresponding to a multiple second liquid inlet port 131, and each inlet hole communicates with a second liquid inlet port 131. The outlet tube sheet 123 has multiple liquid outlet holes, each corresponding to a multiple second liquid outlet port 132, and each outlet hole communicates with a second liquid outlet port 132.

[0053] Furthermore, the self-flowing vibration-damping conformal cooler also includes an inlet end cap 112 and an outlet end cap 122. The inlet end cap 112 is connected to the inlet tube sheet 113 and has a third liquid inlet 111 and a third liquid outlet 121. The outlet end cap 122 is connected to the outlet tube sheet 123. The liquid outlet connecting pipe 124 is disposed inside the shell 100 and is arranged parallel to the heat exchange tube bundle 10. The first end of the liquid outlet connecting pipe 124 passes through the outlet tube sheet 123 and communicates with the outlet end cap 122, and the second end of the liquid outlet connecting pipe 124 passes through the inlet tube sheet 113 and the inlet end cap 112 and communicates with the third liquid outlet 121.

[0054] Specifically, the higher-temperature fluid enters the inlet head 112 through the third inlet 111, then enters the second inlet 131 of each heat exchange tube bundle 10 through the inlet holes on the inlet tube sheet 113, then enters the heat exchange branch pipes 101 of each heat exchange tube bundle 10, then enters the spherical nozzle 102, then enters the heat exchange branch pipes 101 of the next heat exchange tube structure, and the next spherical nozzle 102, and so on. Seawater enters the shell 100 through the first inlet 110. When the higher-temperature fluid flows along the heat exchange tube bundle 10, it exchanges heat with the seawater outside the heat exchange tube bundle 10. The seawater absorbs the heat of the fluid and is discharged through the first outlet 120. The fluid flows out through the second outlet 132 of each heat exchange tube bundle 10, enters the outlet hole of the corresponding outlet tube sheet 123, then enters the outlet connector 124 after passing through the outlet head 122, and finally is discharged through the third outlet 121.

[0055] like Figure 8 As shown, this embodiment of the invention also provides a conformal cooling system, including a heat exchanger 200, a pipeline 300, a pump 400, and a self-flowing vibration-damping conformal cooler. The heat exchanger 200 and the self-flowing vibration-damping conformal cooler are connected to form a circulation loop through the pipeline 300, and the pump 400 is disposed between the heat exchanger 200 and the self-flowing vibration-damping conformal cooler.

[0056] Specifically, pump 400 pumps the higher-temperature fluid in heat exchanger 200 to the heat exchange tube bundle 10 of the self-flowing vibration-damping conformal cooler. Seawater enters the shell 100 through the first inlet 110 and exchanges heat with the higher-temperature fluid. The seawater that has absorbed heat is discharged through the first outlet 120 on the shell 100. The lower-temperature fluid enters the heat exchanger 200 through the self-flowing vibration-damping conformal cooler to cool other equipment in the ship.

[0057] Furthermore, in an embodiment of the present invention, a valve 500 is provided on the pipeline 300 between the self-flowing vibration-damping conformal cooler and the heat exchanger 200 to regulate the flow rate of the fluid entering the heat exchanger 200. Correspondingly, a valve 500 is also provided between the pump 400 and the self-flowing vibration-damping conformal cooler to regulate the flow rate of the fluid entering the self-flowing vibration-damping conformal cooler.

[0058] The conformal cooling system provided in this embodiment of the invention reduces the impact force of seawater on the heat exchange tube bundle inside the self-flowing vibration-damping conformal cooler by setting up a self-flowing vibration-damping conformal cooler, improves the strength of the self-flowing vibration-damping conformal cooler, and thus improves the service life of the conformal cooling system.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
