Description

Technical Field

[0001] The present invention relates to the field of ship power technology, and in particular to a modular ship 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 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.

[0004] Since the conformal heat exchanger of the external conformal cooling system is arranged outside the cabin, it is more susceptible to external environmental impact than the centralized cooler arranged inside the cabin. The heat exchange tube bundle used in the traditional conformal heat exchanger is prone to damage, leakage and blockage under the impact, resulting in inconvenience in maintenance and replacement operations. In addition, marine organisms are easily attached to the surface of the tube bundle, resulting in a decrease in heat exchange capacity and even the cooling system cannot operate normally. Summary of the invention

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 modular marine conformal cooler and conformal cooling system of the present invention are described.

[0030] like Figure 1As shown, in an embodiment of the present invention, a modular ship conformal cooler 100 includes: a plurality of first heat exchange plates 10 and a plurality of second heat exchange plates 20. Each first heat exchange plate 10 is provided with a first flow channel 11 along its length direction, and the liquid inlet end of the first flow channel 11 is connected to seawater. A plurality of second flow channels 12 are provided on both sides of the first flow channel 11, and each second flow channel 12 is connected to the first flow channel 11. The outlet 121 of each second flow channel 12 is arranged perpendicular to the edge of the first heat exchange plate 10, wherein the liquid inlet end of the first flow channel 11 is arranged on the front edge arc surface of the ship's tail wing and faces the bow, and the outlet of the second flow channel 12 is arranged perpendicular to the side arc surface of the tail wing. The plurality of second heat exchange plates 20 are arranged in an interval and stacked manner with the plurality of first heat exchange plates 10, and each second heat exchange plate 20 is provided with a plurality of third flow channels 21, and the second heat exchange plate 20 is used for fluid circulation.

[0031] Specifically, a plurality of first heat exchange plates 10 and a plurality of second heat exchange plates 20 are stacked and welded to form a modular ship conformal cooler 100, and multi-point welding is used between the plates to enhance the impact resistance of the modular ship conformal cooler 100. A first flow channel 11 and a plurality of second flow channels 12 are etched in each first heat exchange plate 10. The first end of the first flow channel 11 is connected to the seawater. After the seawater enters the first flow channel 11, it flows along the second flow channels 12 arranged on both sides of the first flow channel 11 to the edge of the first heat exchange plate 10, and then flows out from the outlet 121 of the second flow channel 12. In this embodiment, each outlet 121 is arranged perpendicular to the edge of the first heat exchange plate 10, so as to utilize the jet effect generated at the outlet 121 to inhibit marine organisms from attaching to the edge of the first heat exchange plate 10. Further, in this embodiment, the liquid inlet end of the first flow channel 11, that is, the first end of the first flow channel 11, is arranged on the arc surface of the leading edge of the tail wing of the ship, and faces the bow direction. The seawater can be driven into the first flow channel 11 by the kinetic pressure of navigation to realize the self-circulation of seawater. A fluid with a relatively high temperature flows in the second heat exchange plate 20 , and the fluid exchanges heat with the seawater to cool the fluid.

[0032] Furthermore, in this embodiment, the first heat exchange plate 10 and the second heat exchange plate 20 are stacked and welded to form a modular ship conformal cooler 100, and the first flow channel 11 and the second flow channel 12 are etched in the first heat exchange plate 10, which has stronger impact resistance than the first flow channel 11 and the second flow channel 12 of the heat exchange tube bundle, thereby improving the service life of the modular ship conformal cooler 100. At the same time, the flow channels are etched in the first heat exchange plate 10 and the second heat exchange plate 20, which is more compact than the traditional shell and tube heat exchanger structure, reduces the volume of the conformal cooler, and realizes the complete integration of the conformal cooler and the hull structure. Further, in this embodiment, the modular ship conformal cooler 100 is modularly arranged with the tail fin, and then connected to the hull of the ship through a flange, which can be replaced as a whole and is easy to maintain.

[0033] The modular ship conformal cooler provided by the embodiment of the present invention, by setting the liquid inlet end of the first flow channel on the curved surface of the leading edge of the ship's tail wing and facing the bow, can use the driving pressure of navigation to drive the seawater to circulate, so that the seawater flushes the first end of the first heat exchange plate, thereby preventing marine organisms from attaching to the first end of the first heat exchange plate; by setting multiple outlets of the second flow channel on the edge of the first heat exchange plate, and each outlet is perpendicular to the edge of the first heat exchanger, the jet effect is used to inhibit the attachment of marine organisms to the edge of the first heat exchange plate, thereby improving the heat exchange capacity of the first heat exchange plate; at the same time, the first flow channel and the second flow channel are formed by etching, which improves the impact resistance of the modular ship conformal cooler compared with the heat exchange tube bundle, thereby improving the service life of the modular ship conformal cooler.

[0034] like Figure 1 As shown, in an embodiment of the present invention, the liquid inlet end of the first flow channel 11 is located at the first end of the first heat exchange plate 10, and the liquid inlet end of the third flow channel 21 is located at the second end of the second heat exchange plate 20, so that the flow direction of the fluid is opposite to the flow direction of seawater.

[0035] Specifically, in this embodiment, seawater flows from the first end to the second end of the first heat exchange plate 10, and the fluid flows from the second end to the first end of the second heat exchange plate 20, so that the flow directions of the seawater and the fluid are opposite, so as to enhance the heat transfer effect on both sides of the seawater and the fluid through countercurrent heat exchange.

[0036] like Figure 2 and Figure 5 As shown, in an embodiment of the present invention, the multiple second flow channels 12 are divided into a first group of second flow channels 12 and a second group of second flow channels 12, the first group of second flow channels 12 and the second group of second flow channels 12 are symmetrically arranged on both sides of the first flow channel 11, and the multiple second flow channels 12 in each group are arranged in parallel along the length direction of the first flow channel 11, and the angle between each second flow channel 12 and the first flow channel 11 is an acute angle.

[0037] Specifically, in this embodiment, the first flow channel 11, the first group of second flow channels 12 and the second group of second flow channels 12 are arranged in a tree-like structure, which can distribute the seawater in the first flow channel 11 to each second flow channel 12. The outlet 121 of each group of second flow channels 12 is arranged along the edge of the first heat exchange plate 10, and each outlet 121 is arranged perpendicular to the edge of the first heat exchange plate 10. The jet effect of each outlet 121 can be used to inhibit the growth of marine organisms at the edge of the first heat exchange plate 10, thereby preventing marine organisms from growing on most of the surface of the first heat exchange plate 10.

[0038] like Figure 3 and Figure 4As shown, in an embodiment of the present invention, a plurality of third flow channels 21 are divided into a first group of third flow channels 21 and a second group of third flow channels 21, the positions of the first group of third flow channels 21 are aligned with the positions of the first group of second flow channels 12, the positions of the second group of third flow channels 21 are aligned with the positions of the second group of second flow channels 12, the first group of third flow channels 21 are orthogonally arranged to the first group of second flow channels 12, and the second group of third flow channels 21 are orthogonally arranged to the second group of second flow channels 12.

[0039] Specifically, if Figure 4 As shown, the third flow channel 21 is arranged orthogonally to the second flow channel 12, and the flow trajectories of seawater and fluid are crossed, thereby realizing cross-flow efficient heat exchange, enhancing the compactness of the modular ship conformal cooler 100, realizing the lightweight of the modular ship conformal cooler 100, and improving the impact resistance of the modular ship conformal cooler 100.

[0040] As shown in Figure 2, in an embodiment of the present invention, each first heat exchange plate 10 is provided with a first inlet 13, a first outlet 14 and a second outlet 15. The first inlet 13 is arranged adjacent to the end of the first flow channel 11, and the first outlet 14 and the second outlet 15 are respectively located on both sides of the first flow channel 11 and are arranged adjacent to the liquid inlet end of the first flow channel 11.

[0041] Specifically, in this embodiment, the liquid inlet end of the first flow channel 11 is the first end of the first heat exchange plate 10 , and the end of the first flow channel 11 is close to the second end of the first heat exchange plate 10 .

[0042] like Figure 3 As shown, in the embodiment of the present invention, each second heat exchange plate 20 is provided with a second inlet 22, a third outlet 23 and a fourth outlet 24. The second inlet 22 is communicated with the first end of the first group of third flow channels 21 and the first end of the second group of third flow channels 21, the third outlet 23 is communicated with the second end of the first group of third flow channels 21, and the fourth outlet 24 is communicated with the second end of the second group of third flow channels 21.

[0043] Specifically, the fluid with a higher temperature enters the first group of third flow channels 21 and the second group of third flow channels 21 from the second inlet 22. After the fluid exchanges heat with the seawater during the flow, the fluid in the first group of third flow channels 21 is discharged from the third outlet 23, and the fluid in the second group of third flow channels 21 is discharged from the fourth outlet 24.

[0044] like Figure 4 and Figure 6As shown, in an embodiment of the present invention, a plurality of first inlets 13 and a plurality of second inlets 22 are aligned to form a liquid inlet channel 30, a plurality of first outlets 14 and a plurality of third outlets 23 are aligned to form a first liquid outlet channel 40, a plurality of second outlets 15 and a plurality of fourth outlets 24 are aligned to form a second liquid outlet channel 50, the liquid inlet channel 30 is used to inject fluid, and the first liquid outlet channel 40 and the second liquid outlet channel 50 are used to discharge fluid.

[0045] Specifically, 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 13 and the plurality of second inlets 22 are aligned and have the same aperture, thereby forming a liquid inlet channel 30; accordingly, the plurality of first outlets 14 and the plurality of third outlets 23 are aligned and have the same aperture, thereby forming a first liquid outlet channel 40; the plurality of second outlets 15 and the plurality of fourth outlets 24 are aligned and have the same aperture, thereby forming a second liquid outlet channel 50. The fluid with a higher temperature enters the first group of third flow channels 21 and the second group of third flow channels 21 of each second heat exchange plate 20 from the liquid inlet channel 30, and after heat exchange with the seawater in the first heat exchange plate 10, the fluid in the first group of third flow channels 21 flows out from the first liquid outlet channel 40, and the fluid in the second group of third flow channels 21 flows out from the second liquid outlet channel 50.

[0046] like Figure 1 As shown, in an embodiment of the present invention, the shape of the second heat exchange plate 20 is the same as that of the first heat exchange plate 10, the outer contour of the first heat exchange plate 10 is streamlined, the length of the first heat exchange plate 10 is greater than the width of the first heat exchange plate 10, and the width of the first end of the first heat exchange plate 10 is greater than the width of the second end of the first heat exchange plate 10, wherein the first end is the upstream end.

[0047] Specifically, in this embodiment, the first heat exchange plate 10 and the second heat exchange plate 20 are both airfoil structures, and the outer contours of the first heat exchange plate 10 and the second heat exchange plate 20 are streamlined to reduce the resistance of seawater when it flows.

[0048] Furthermore, the end surface of the first end of the first heat exchange plate 10 is an arc-shaped end surface, so as to reduce the attachment area of ​​marine organisms, thereby inhibiting the growth of marine organisms on the end surface of the first end of the first heat exchange plate 10 .

[0049] like Figure 7 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 modular ship conformal cooler 100. Along the forward direction of the ship, the modular ship conformal cooler 100 is located behind the propeller 500 of the ship, and the modular ship conformal cooler 100 is connected to the heat exchanger 200 through the pipeline 400 to form a circulation loop, and the pump 300 is arranged between the modular ship conformal cooler 100 and the heat exchanger 200.

[0050] Specifically, the liquid inlet end of the first flow channel 11 of the first heat exchange plate 10 of the modular ship conformal cooler 100 is arranged on the arc surface of the leading edge of the ship's bulbous bow, and faces the bulbous bow, and is located in the bow stagnation area of ​​the bulbous bow. The seawater can be driven into the first flow channel 11 by the operating pressure of the navigation, and discharged from the second flow channel 12 to realize the self-circulation of seawater. The first flow channel 11 of the first heat exchange plate 10 is located behind the propeller 500. The jet generated when the propeller 500 is running can drive the seawater into the first flow channel 11, providing additional driving force for the seawater to enter the modular ship conformal cooler 100, thereby improving the heat exchange capacity of the modular ship conformal cooler 100, and further improving the heat exchange capacity of the conformal cooling system.

[0051] The two ends of the pipeline 400 are connected to the two ends of the third flow channel 21 of the second heat exchange plate 20 of the modular ship 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 first end of the third flow channel 21, and the fluid flows along the third flow channel 21 to exchange heat with the seawater in the first heat exchange plate 10. The fluid with a lower temperature enters the heat exchanger 200 from the second end of the third 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 prevents marine organisms from growing on the surface of the modular ship conformal cooler by setting a modular ship conformal cooler, thereby improving the heat exchange capacity of the modular ship conformal cooler; by setting the inlet flow channel of the first heat exchange plate of the modular ship conformal cooler on the arc surface of the leading edge of the bulbous bow of the ship, water is supplied by pressure difference, and self-circulation of seawater is realized. The modular ship conformal cooler is set behind the propeller, and the jet generated when the propeller is running can be used to drive the seawater into the inlet flow channel, providing additional driving force for the seawater to enter the modular ship conformal cooler. 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 modular ship conformal cooler is processed by stacking and diffusion welding of etched metal plates. Compared with the traditional shell and tube heat exchanger, the structure is compact, the volume of the modular ship conformal cooler is reduced, and the conformal cooler is completely integrated with the hull structure.

[0053] Furthermore, one end of the pipeline 400 is connected to the liquid inlet channel 30 of the modular ship conformal cooler 100, and the other end is connected to the first liquid outlet channel 40 and the second liquid outlet channel 50 of the modular ship conformal cooler 100. The pump 300 pumps the higher temperature fluid 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 third flow channel 21, and exchanges heat with the seawater in the first heat exchange plate 10. The fluid with reduced temperature enters the first liquid outlet channel 40 from the third outlet 23 of the second heat exchange plate 20, enters the second liquid outlet channel 50 from the fourth outlet 24, and then enters the heat exchanger 200 to cool other equipment in the ship.

[0054] 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 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.
