Description

Technical Field

[0001] The present invention relates to the field of ship power technology, and in particular to a self-flowing conformal cooler and a 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 shortcomings: on the one hand, it occupies a large amount of cabin volume and reduces 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.

It is not easy to arrange it in the priority structure outside the hull, and it is difficult to achieve complete integration of the cooler and the hull structure.

[0024] 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.

[0025] 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.

[0026] Combine the following Figure 1-Figure 4 The self-flowing conformal cooler and conformal cooling system of the present invention are described.

[0027] like Figure 1 As shown, in an embodiment of the present invention, the self-flowing conformal cooler includes: a plurality of first heat exchange plates 10 and a plurality of second heat exchange plates 20. The plurality of first heat exchange plates 10 and the plurality of second heat exchange plates 20 are stacked and arranged at intervals to form a self-flowing conformal cooler 100. Each first heat exchange plate 10 is provided with a plurality of first flow channels 11, the first end of the first flow channel 11 is used to inject seawater, the first end of the first flow channel 11 is arranged on the arc surface of the leading edge of the bulbous bow of the ship and faces the bulbous bow, the second end of the first flow channel 11 is used to discharge seawater, the second end of the first flow channel 11 is arranged on the side of the bulbous bow and faces the stern, wherein some of the first flow channels 11 are wavy flow channels. Each second heat exchange plate 20 is provided with a second flow channel 21, the first end of the second flow channel 21 is used to discharge fluid, the second end of the second flow channel 21 is used to inject fluid, and the flow direction of the fluid is opposite to the flow direction of the seawater.

[0028] Specifically, in this embodiment, the self-flowing conformal cooler 100 is formed by stacking and welding a plurality of first heat exchange plates 10 and a plurality of second heat exchange plates 20. A plurality of first flow channels 11 are etched in the first heat exchange plate 10, and seawater flows in the first flow channels 11. The first end of the first flow channel 11 is located on the arc surface of the leading edge of the bulbous bow of the ship and faces the bulbous bow, and is in the bow stagnation area of ​​the bulbous bow. The second end of the first flow channel 11 is located on the side of the bulbous bow of the ship and faces the stern, and is in the separation negative pressure area on the side of the bulbous bow. This setting can generate a large driving pressure, which prompts the seawater to automatically enter the first flow channel 11 and then automatically discharge.

[0029] A plurality of second flow channels 21 are etched in the second heat exchange plate 20, and a fluid with a higher temperature flows in the second flow channel 21, and the flow direction of the fluid is opposite to that of the seawater, so as to strengthen the bilateral convection. Furthermore, part of the first flow channel 11 is a wavy flow channel, which can cause the seawater to generate a flow vortex during the flow process, and the flow vortex can not only play a role in strengthening heat exchange, but also reduce the resistance of the first flow channel 11, thereby improving the heat exchange efficiency of the conformal cooler.

[0030] Furthermore, in this embodiment, the first heat exchange plate 10 and the second heat exchange plate 20 are stacked and welded to form a conformal cooler, and the first flow channel 11 and the second flow channel 21 are etched. Compared with the traditional shell and tube heat exchanger, the structure is compact, the volume of the conformal cooler is reduced, and the conformal cooler is completely integrated with the hull structure.

[0031] The gravity-flow conformal cooler provided in the embodiment of the present invention realizes the self-circulation of seawater by arranging the first end of the first flow channel of the first heat exchange plate on the arc surface of the leading edge of the bulbous bow of the ship and the second end on the side of the bulbous bow, and utilizing the pressure difference to supply water; by setting the flow direction of the seawater and the flow direction of the fluid to be opposite, the bilateral convection is enhanced and the heat exchange capacity of the conformal cooler is improved; by setting part of the flow channel of the first flow channel as a wavy flow channel, the function of reducing the drag of the traveling wave is achieved, the flow resistance of the seawater flow channel is reduced, and the heat exchange efficiency of the conformal cooler is improved.

[0032] like Figure 1 As shown, in an embodiment of the present invention, each first heat exchange plate 10 is provided with a first inlet 12 and a first outlet 13, and each second heat exchange plate 20 is provided with a second inlet 22 and a second outlet 23, the second inlet 22 is connected to the second end of the second flow channel 21, and the second outlet 23 is connected to the first end of the second flow channel 21; wherein, a plurality of second inlets 22 are positioned opposite to a plurality of first inlets 12 to form a liquid inlet channel 30, and a plurality of second outlets 23 are positioned opposite to a plurality of first outlets 13 to form a liquid outlet channel 40, and the fluid enters each second flow channel 21 from the liquid inlet channel 30, and then flows out from the liquid outlet channel 40.

[0033] Specifically, each first heat exchange plate 10 is provided with a first inlet 12 and a first outlet 13, and the first inlet 12 and the first outlet 13 are not connected to the first flow channel 11. Each second heat exchange plate 20 is provided with a second inlet 22 and a second outlet 23, and the second inlet 22 and the second outlet 23 are both connected to the second flow channel 21. After the plurality of first heat exchange plates 10 and the plurality of second heat exchange plates 20 are stacked, the plurality of first inlets 12 and the plurality of second inlets 22 are aligned and have the same aperture, thereby forming a liquid inlet channel 30. Correspondingly, the plurality of first outlets 13 and the plurality of second outlets 23 are also aligned and have the same aperture, thereby forming a liquid outlet channel 40. The fluid with a higher temperature enters each second heat exchange plate 20 through the liquid inlet channel 30, flows along the second flow channel 21, and is discharged from the liquid outlet channel 40. Seawater flows along the first flow channel 11 of each first heat exchange plate 10, and is discharged from the first heat exchange plate 10 through the second end of the first flow channel 11 after heat exchange with the fluid.

[0034] Furthermore, in this embodiment, the first heat exchange plate 10 and the second heat exchange plate 20 have the same shape, the width of the first end of the first heat exchange plate 10 is smaller than the width of the second end of the first heat exchange plate 10, and the first end of the first heat exchange plate 10 is arc-shaped.

[0035] Specifically, the first end of the first heat exchange plate 10 is the flow-facing end. The first end of the first heat exchange plate 10 is configured to be arc-shaped and have a small size, which can reduce resistance and facilitate seawater to enter the first flow channel 11.

[0036] Furthermore, the liquid inlet end of the first flow channel 11 is located at the first end of the first heat exchange plate 10, the liquid outlet end of the first flow channel 11 is located at the second end of the first heat exchange plate 10, the liquid inlet end of the second flow channel 21 is located at the second end of the second heat exchange plate 20, and the liquid outlet end of the second flow channel 21 is located at the first end of the second heat exchange plate 20.

[0037] Specifically, the liquid inlet end of the first flow channel 11 is the seawater inlet end, which is located at the first end of the first heat exchange plate 10, that is, the seawater enters from the first end of the first heat exchange plate 10. The liquid inlet end of the second flow channel 21 is the fluid inlet end, which is located at the second end of the second heat exchange plate 20, so that the flow direction of the seawater in the first flow channel 11 is exactly opposite to the flow direction of the fluid in the second flow channel 21, so as to enhance the bilateral convection. Further, it can be seen that the first inlet 12 is located at the second end of the first heat exchange plate 10, the second inlet 22 is located at the second end of the second heat exchange plate 20, the first outlet 13 is located near the first end of the first heat exchange plate 10, and the second outlet 23 is located near the first end of the second heat exchange plate 20.

[0038] like Figure 2As shown, in an embodiment of the present invention, the first flow channel 11 includes a first inlet flow channel 111, a first transition flow channel 112 and an outlet flow channel 113 connected in sequence. The first inlet flow channel 111 is used to inject seawater, the outlet flow channel 113 is used to discharge seawater, and the first transition flow channel 112 is a wavy flow channel.

[0039] Specifically, in this embodiment, the first transition channel 112 is the longest. Setting the first transition channel 112 as a wavy channel can cause the seawater to generate flow vortices during the flow process, thereby enhancing heat exchange and reducing the flow resistance of the seawater heat exchange channel.

[0040] Furthermore, if Figure 2 As shown, in the embodiment of the present invention, the first heat exchange plate 10 is further provided with: a first platform 14 and a second platform 15. The first platform 14 is located between the plurality of first transition flow channels 112 to separate the plurality of first transition flow channels 112 into two parts, and the first outlet 13 is located on the first platform. The second platform 15 is located between the plurality of outlet flow channels 113 to separate the plurality of outlet flow channels 113 into two parts, and the first inlet 12 is located on the second platform 15.

[0041] Specifically, in this embodiment, a plurality of first transition channels 112 are etched on both sides of the first platform 14, a plurality of first inlet channels 111 are etched at the front end of the first platform 14, and each first inlet channel 111 is connected to a first transition channel 112. The second platform 15 is connected to the first platform 14, a plurality of outlet channels 113 are etched on both sides of the second platform 15, and each outlet channel 113 is connected to a first transition channel 112.

[0042] Furthermore, in this embodiment, one end of the first platform 14 close to the first inlet flow channel 111 is in a wedge-shaped shape to reduce the flow resistance of the fluid.

[0043] Optionally, the setting direction of the outlet flow channel 113 is related to the shape of the second platform 15. When the surface of the second platform 15 adjacent to the outlet flow channel 113 is a plane, the outlet flow channel 113 is arranged parallel to the axis of the first heat exchange plate 10; when the surface of the second platform 15 adjacent to the outlet flow channel 113 is an inclined surface, the outlet flow channel 113 is arranged at an angle to the axis of the first heat exchange plate 10. Specifically, Figure 2 As shown, in this embodiment, the surface of the second platform 15 adjacent to the outlet flow channel 113 is an inclined surface, and the outlet flow channels 113 located on both sides of the second platform 15 are arranged parallel to the inclined surface, so that the seawater flowing through the outlet flow channel 113 is discharged to both sides of the first heat exchange plate 10.

[0044] like Figure 3As shown, in the embodiment of the present invention, the second flow channel 21 includes a connected second inlet flow channel 211 and a second transition flow channel 212. The second inlet flow channel 211 is in communication with the second inlet 22, and the second transition flow channel 212 is a wave-shaped flow channel.

[0045] Specifically, the second transition flow channel 212 is configured as a wavy flow channel, so that the fluid can generate a flow vortex during the flow process, thereby enhancing heat exchange and reducing the flow resistance of the fluid heat exchange channel.

[0046] Furthermore, the second heat exchange plate 20 further includes a confluence cavity 24, which is in communication with a plurality of second transition channels 212, and is also in communication with the second outlet 23. Specifically, the fluid with a higher temperature enters the second inlet channel 211 from the second inlet 22, flows through the second transition channel 212, enters the confluence cavity 24, and is then discharged from the second outlet 23.

[0047] Furthermore, if Figure 3 As shown, the second heat exchange plate 20 is also provided with a third platform 26, which is located between the multiple second transition flow channels 212 to separate the multiple second transition flow channels 212 into two parts. The third platform 26 is provided with a converging flow channel 25, and the two ends of the converging flow channel 25 are respectively connected to the converging cavity 24 and the second outlet 23.

[0048] Specifically, multiple second transition channels 212 are etched on both sides of the third platform 26, multiple second inlet channels 211 are etched between the second inlet 22 and the first end of the second transition channel 212, and one end of each second inlet channel 211 is connected to the second inlet 22, and the other end is connected to a second transition channel 212. A confluence cavity 24 is etched at the first end of the second heat exchange plate 20, and a confluence channel 25 is etched at one end of the third platform 26 close to the confluence cavity 24, and the two ends of the confluence channel 25 are respectively connected to the confluence cavity 24 and the second outlet 23. The fluid with a higher temperature enters the second inlet channel 211 from the second inlet 22, flows through the second transition channel 212, enters the confluence cavity 24, and then flows through the confluence channel 25 to enter the second outlet 23 for discharge.

[0049] like Figure 4 As shown, an embodiment of the present invention further provides a conformal cooling system, including a heat exchanger 200, a pump 300, a pipeline 400 and a plurality of self-flowing conformal coolers 100. The self-flowing conformal cooler 100 and the heat exchanger 200 are connected to form a circulation loop through the pipeline 400, and the pump 300 is arranged between the self-flowing conformal cooler 100 and the heat exchanger 200.

[0050] Specifically, the first end of the first flow channel 11 of the first heat exchange plate 10 of the gravity-flow conformal cooler 100 is arranged on the arc surface of the leading edge of the bulbous bow of the ship and faces the bulbous bow, and is located in the bow stagnation area of ​​the bulbous bow. The second end of the first flow channel 11 is located on the side of the bulbous bow of the ship and faces the stern, and is located in the separation negative pressure area on the side of the bulbous bow. A larger driving pressure can be generated, which prompts seawater to automatically enter from the first end of the first flow channel 11 and be discharged from the second end.

[0051] The two ends of the pipeline 400 are connected to the two ends of the second flow channel 21 of the second heat exchange plate 20 of the self-flow conformal cooler 100, and the heat exchanger 200 and the pump 300 are also arranged on the pipeline 400. The pump 300 pumps the fluid with a higher temperature in the heat exchanger 200 to the second end of the second flow channel 21, and the fluid flows along the second flow channel 21 to exchange heat with the seawater in the first heat exchange plate 10. The fluid with a lowered temperature enters the heat exchanger 200 from the first end of the second flow channel 21 of the second heat exchange plate 20 to cool other equipment in the ship.

[0052] The conformal cooling system provided by the embodiment of the present invention realizes self-circulation of seawater by arranging the first end of the first flow channel of the first heat exchange plate of the self-flowing conformal cooler on the arc surface of the leading edge of the bulbous bow of the ship, and the second end on the side of the bulbous bow, and utilizing the pressure difference to supply water. There is no need to set up a pump to pump the seawater, thereby reducing the power consumption of the conformal cooling system. At the same time, the self-flowing conformal cooler is processed by stacking and diffusion welding of etched metal plates, and has a compact structure compared to the traditional shell and tube heat exchanger, thereby realizing the complete integration of the conformal cooler and the hull structure.

[0053] Furthermore, one end of the pipeline 400 is connected to the liquid inlet channel 30 of the self-flowing conformal cooler 100, and the other end is connected to the liquid outlet channel 40 of the self-flowing conformal cooler 100. The pump 300 pumps the fluid with a higher temperature in the heat exchanger 200 to the liquid inlet channel 30. The fluid enters each second heat exchange plate 20 from the liquid inlet channel 30, flows along the second flow channel 21, and exchanges heat with the seawater in the first heat exchange plate 10. The fluid with reduced temperature enters the liquid outlet channel 40 from the second outlet 23 of the second heat exchange plate 20, and then enters the heat exchanger 200 to cool other equipment in the ship.
