Description

Technical Field

[0001] The present invention relates to the technical field of ship cooling systems, and in particular to a vibration suppression enhanced conformal cooler and a conformal cooling system. Background Art

[0002] There are a large number of seawater coolers in the ship power system. Traditional ships use decentralized cooling technology, that is, the seawater cooling area is dispersed in the power compartment, and seawater is provided to the cooler through decentralized water supply pipelines, resulting in the following deficiencies: on the one hand, the seawater cooling area occupies a large amount of cabin volume, reducing the effective carrying capacity of the ship; on the other hand, the pipeline system connecting the seawater cooler is prone to damage under the combined effects of long-term sea corrosion, scouring, and pressure, resulting in water leakage in the cabin, affecting the safety and reliability of the ship's navigation.

[0003] For this reason, central cooling technology is widely used in new ships. The centralized cooler cools fresh water, and then the fresh water is used to indirectly cool the original seawater cooler, which can achieve the purpose of reducing the seawater boundary and improving the reliability of ship operation. However, in the central cooling system, since the cooling load is discharged to the outside through the centralized cooler, the equipment is bulky and occupies cabin space. In response to the above problems, researchers proposed external conformal cooling technology, which increases the utilization rate of the internal cabin by conforming the centralized cooler to the hull structure.

[0004] Existing conformal cooling technologies mostly use tube-in-tube cooling technology, and the heat exchange interface between cold and hot media is a thin-walled heat exchange tube. During the operation of the conformal cooling system, the heat exchange tube bundle is horizontally flushed by seawater outside the tube, causing flow-induced vibration in the heat exchange tube bundle, which will cause mechanical wear or fatigue damage during long-term operation; and during external impact in the marine environment, the heat exchange tube has a weak load-bearing capacity, and the reliability of the conformal cooler and conformal cooling system is not high.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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.

[0028] The features of the terms "first" and "second" in the specification and claims of the present invention may include one or more of the features explicitly or implicitly. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0029] Combine the following Figure 1-Figure 7 The vibration suppression enhanced conformal cooler and conformal cooling system of the present invention are described.

[0030] like Figure 1As shown, in an embodiment of the present invention, the vibration suppression enhanced conformal cooler includes a shell 100, in which a plurality of heat exchange tube bundles 10 are arranged, each heat exchange tube bundle 10 includes a plurality of heat exchange tube structures and a plurality of spherical nozzles 102, the plurality of heat exchange tube structures are sequentially arranged along the length direction of the shell 100, and two adjacent heat exchange tube structures are connected by the spherical nozzle 102 to form a heat exchange tube bundle 10. Each heat exchange tube structure includes a plurality of heat exchange branch pipes 101, the plurality of heat exchange branch pipes 101 are arranged in an annular shape, and the plurality of heat exchange branch pipes 101 are connected to a spherical nozzle 102.

[0031] Specifically, in this embodiment, each heat exchange tube bundle 10 is composed of multiple heat exchange tube structures and multiple spherical nozzles 102. Each heat exchange tube structure includes multiple heat exchange branches 101. The multiple heat exchange branches 101 are arranged in a ring. After passing through each heat exchange branch 101, the fluid converges into a spherical nozzle 102, and then is diverted by the spherical nozzle 102 to enter the multiple heat exchange branches 101 of the next heat exchange tube structure, and flows in this way until the fluid flows out of the shell 100.

[0032] In this embodiment, if Figure 2 As shown, from the side of the shell 100, each heat exchange tube bundle 10 is a unit cell structure, and multiple heat exchange tube bundles 10 are arranged in sequence to form a compact unit cell body. When seawater impacts the heat exchange tube bundle 10 laterally, the compact unit cell body reduces the turbulent vibration caused by the impact of seawater on the heat exchange tube bundle 10, thereby improving the impact resistance of the heat exchange tube bundle 10. At the same time, the periodic arrangement of multiple heat exchange tube bundles 10 can produce a complex spatial turbulence effect, so that the seawater entering the shell 100 flushes the heat exchange tube bundle 10 laterally, longitudinally and obliquely, effectively enhancing the heat exchange capacity of the vibration suppression enhanced conformal cooler.

[0033] Optionally, the pattern formed by the circular arrangement of the multiple heat exchange branches 101 can be a hexagon or an octagon, etc. It can be understood that the more heat exchange branches 101 included 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 the multiple heat exchange tube bundles 10.

[0034] The vibration suppression enhanced conformal cooler provided in an embodiment of the present invention, by configuring each heat exchange tube bundle as a heat exchange tube structure in which multiple heat exchange branch tubes are arranged in a ring shape, the multiple heat exchange tube bundles can form a closely arranged unit cell body after being arranged, thereby reducing the turbulent vibration caused by the impact of seawater on the heat exchange tube bundle, and improving the impact resistance of the heat exchange tube bundle; at the same time, the periodic arrangement of the multiple heat exchange tube bundles can produce a complex spatial turbulence effect, so that the seawater entering the shell flushes the heat exchange tube bundle horizontally, vertically and obliquely, effectively enhancing the heat exchange capacity of the conformal cooler.

[0035] Furthermore, if Figure 2 and Figure 3 As shown, in the embodiment of the present invention, the side view shape of each heat exchange tube structure is a hexagon. Specifically, in this embodiment, each heat exchange tube structure includes 6 heat exchange branch tubes 101, and the 6 heat exchange branch tubes 101 are arranged in a ring to form a hexagon.

[0036] like Figure 4 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 arranged obliquely, the third pipe 1013 and the second end of the second pipe 1012 are arranged obliquely, and the first pipe 1011 and the third pipe 1013 are respectively connected to two adjacent spherical pipes 102.

[0037] 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-tube triangular support structure to suppress the vibration of the heat exchange tube bundle 10 under seawater excitation.

[0038] like Figure 4 As shown, in the embodiment of the present invention, each heat exchange tube bundle 10 further includes: a plurality of first liquid inlets 141 and a plurality of first liquid outlets 142. Each first liquid inlet 141 is connected to one end of a heat exchange tube bundle 10, and each first liquid outlet 142 is connected to the other end of a heat exchange tube bundle 10.

[0039] Specifically, the flow of the fluid in each heat exchange tube bundle 10 is as follows: Figure 5 As shown, the higher temperature fluid entering the shell 100 passes through the first liquid inlet 141 and enters into multiple heat exchange branches 101 of a heat exchange tube structure, then converges into the spherical connecting pipe 102, and then enters into multiple heat exchange branches 101 of the next heat exchange tube structure, flowing in sequence until it flows out from the first liquid outlet 142.

[0040] like Figure 1 As shown, in the embodiment of the present invention, the side wall of the housing 100 is provided with two openings, one of the two openings is used for introducing seawater, and the other opening is used for discharging seawater.

[0041] Specifically, seawater enters the shell 100 from an opening, washes the heat exchange tube bundle 10 horizontally, vertically and obliquely, exchanges heat with the fluid with a higher temperature in the heat exchange tube bundle 10, and then is discharged from the shell 100 from another outlet.

[0042] Furthermore, in the above-mentioned embodiment, the vibration suppression enhanced conformal cooler further includes a pair of drainage mechanisms, the two drainage mechanisms are respectively arranged at the two openings, the first end of each drainage mechanism is rotatably connected to the shell 100, and the second end of each drainage mechanism is a free end. When the ship is stationary, the second end of the drainage mechanism overlaps the shell 100 to close the opening; when the ship is sailing, under the action of seawater, the second end of the drainage mechanism can move away from the shell 100 to open the opening; wherein, the movement directions of the second ends of the two drainage mechanisms are opposite.

[0043] Specifically, when the ship is in a stationary state, the impact force of seawater on the drainage mechanism is relatively small. At this time, the second end of the drainage mechanism overlaps the shell 100, thereby closing the two openings on the shell 100; when the ship is in a sailing state, the impact force of seawater on the drainage mechanism is relatively large. Along the traveling direction of the ship, one of the two drainage mechanisms located in the front is impacted by seawater, and the second end of the drainage mechanism rotates relative to the first end, thereby making the opening in an open state. At this time, seawater enters the shell 100, and when the seawater that absorbs heat flows to the other opening, under the action of the gravity of the seawater, the second end of the second drainage mechanism rotates relative to the first end, thereby making the second opening in an open state, so that the seawater can be discharged from the shell 100.

[0044] Furthermore, in this embodiment, the second ends of the two drainage mechanisms move in opposite directions. When the ship reverses in an emergency, the opening originally discharging seawater can be used as a seawater inlet, and the opening originally injecting seawater can be used as a seawater outlet.

[0045] Furthermore, if Figure 1 As shown, in an embodiment of the present invention, each drainage mechanism includes an elastic member 131 and a drainage plate 132. The first end of the elastic member 131 is connected to the housing 100, and the first end of the drainage plate 132 is connected to the second end of the elastic member 131, wherein, when the ship is in a sailing state, under the action of seawater, the second end of the drainage plate 132 can move in a direction away from the housing 100; when the ship is in a stationary state, the second end of the drainage plate 132 overlaps the housing 100.

[0046] Specifically, when the ship is in a sailing state, along the forward direction of the ship, a guide plate 132 located in the front moves in a direction away from the shell 100 under the impact of seawater, the elastic member 131 is deformed, and the opening at the position of the guide plate 132 is in an open state to allow seawater to enter the shell 100. The seawater that absorbs heat pushes a guide plate 132 at the rear to move in a direction away from the shell 100 under the action of gravity, thereby making the opening therein in an open state, and then discharging the seawater.

[0047] When the ship stops sailing, the impact force of the seawater on the front guide plate 132 becomes smaller, and the elastic member 131 is reset to drive the second end of the guide plate 132 to move toward the shell 100, thereby closing the opening there. When the gravity of the seawater in the shell 100 is not enough to overcome the elastic force of the elastic member 131, the rear elastic member 131 drives the rear guide plate 132 to reset to close the rear opening.

[0048] Furthermore, in this embodiment, the navigation speed of the ship is proportional to the impact force of seawater on the guide plate, and the impact force of seawater is positively correlated with the degree of opening of the opening. The faster the navigation speed of the ship, the greater the impact force of seawater on the guide plate, and the greater the degree of opening of the opening. When the navigation speed of the ship is slow, the impact force of seawater on the guide plate is small. At this time, the degree of opening of the opening is small, and then the amount of seawater in the shell 100 is small, and the impact force of seawater on the heat exchange tube bundle 10 will also be reduced accordingly.

[0049] The vibration suppression enhanced conformal cooler provided in an embodiment of the present invention is characterized in that an elastic member and a guide plate are arranged at the opening of the shell. The degree of opening of the guide plate and the shell is positively correlated with the sailing speed of the ship. Therefore, the amount of seawater entering the shell can be automatically adjusted according to the sailing speed, so as to reduce the impact force of the seawater on the heat exchange tube bundle, suppress the vibration of the heat exchange tube bundle, and increase the service life of the vibration suppression enhanced conformal cooler.

[0050] like Figure 1 As shown, in an embodiment of the present invention, the vibration suppression enhanced conformal cooler further includes an inlet tube sheet 110 and an outlet tube sheet 120. The inlet tube sheet 110 and the outlet tube sheet 120 are respectively arranged at both ends of the shell 100, and the inlet tube sheet 110 is provided with a plurality of liquid inlet holes, and the plurality of liquid inlet holes are arranged in a one-to-one correspondence with the plurality of first liquid inlet ports 141, and each liquid inlet hole is connected to a first liquid inlet port 141. The outlet tube sheet 120 is provided with a plurality of liquid outlet holes, and the plurality of liquid outlet holes are arranged in a one-to-one correspondence with the plurality of first liquid outlet ports 142, and each liquid outlet hole is connected to a first liquid outlet port 142.

[0051] Furthermore, the vibration suppression enhanced conformal cooler further includes an inlet head 111 and an outlet head 121. The inlet head 111 is connected to the inlet tube sheet 110 and is provided with a second liquid inlet 112. The outlet head 121 is connected to the outlet tube sheet 120 and is provided with a second liquid outlet 122.

[0052] Specifically, the fluid with a higher temperature enters the inlet head 111 from the second liquid inlet 112, then enters the first liquid inlet 141 of each heat exchange tube bundle 10 from each liquid inlet hole on the inlet tube sheet 110, then enters each heat exchange branch 101 of each heat exchange tube bundle 10, then enters the spherical pipe 102, then enters each heat exchange branch 101 of the next heat exchange tube structure, and the next spherical pipe 102, and flows in sequence. When the fluid with a higher temperature flows along the heat exchange tube bundle 10, heat exchange occurs with the seawater outside the heat exchange tube bundle 10, and the seawater absorbs the heat of the fluid. The fluid flows out from the first liquid outlet 142 of each heat exchange tube bundle 10, enters the corresponding liquid outlet hole of the outlet tube sheet 120, and then passes through the outlet head 121 and is discharged from the second liquid outlet 122.

[0053] like Figure 6 and Figure 7 As shown, an embodiment of the present invention further provides a conformal cooling system, including a heat exchanger 200, a pipeline 300, a pump 400 and a vibration suppression enhanced conformal cooler. The heat exchanger 200 and the vibration suppression enhanced conformal cooler are connected to form a circulation loop through the pipeline 300, and the pump 400 is arranged between the heat exchanger 200 and the vibration suppression enhanced conformal cooler.

[0054] Specifically, the pump 300 pumps the fluid with a higher temperature in the heat exchanger 200 into the heat exchange tube bundle 10 of the vibration suppression enhanced conformal cooler, and the seawater enters the shell 100 from the opening on the shell 100 to exchange heat with the fluid with a higher temperature. The seawater that absorbs heat is discharged from another opening on the shell 100, and the fluid with a lower temperature enters the heat exchanger 200 from the vibration suppression enhanced conformal cooler to cool other equipment in the ship.

[0055] Furthermore, in the embodiment of the present invention, a valve 500 is provided on the pipeline 300 between the vibration suppression enhanced conformal cooler and the pump 400 to adjust the flow rate of the fluid entering the heat exchanger 200 .

[0056] The conformal cooling system provided by the embodiment of the present invention reduces the impact force of seawater on the heat exchange tube bundle in the vibration suppression enhanced conformal cooler by providing a vibration suppression enhanced conformal cooler, improves the strength of the vibration suppression enhanced conformal cooler, and further improves the service life of the conformal cooling system.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
