[0002] To reduce sea access, modern large ships generally adopt centralized cooling technology, using centralized coolers to indirectly cool users with seawater.

DETAILED DESCRIPTION

[0025] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0026] The features of the terms "first" and "second" in the description and claims of the present invention may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more.

[0027] The following combination Figure 1-Figure 7 The modular longitudinal flow conformal cooler and conformal cooling system of the present invention are described.

[0028] like Figure 1 and Figure 2As shown, in an embodiment of the present invention, a modular longitudinal flow conformal cooler includes: a housing 100, a plurality of flow spoilers 10, a plurality of heat exchange tubes 20, a water retaining mechanism 130, and a drain mechanism 140. A first liquid inlet 112 and a first liquid outlet 122 are respectively provided at both ends of the housing 100. The plurality of heat exchange tubes 20 are arranged sequentially along the width of the housing 100. The first end of each heat exchange tube 20 is connected to the first liquid inlet 112, and the second end of each heat exchange tube 20 is connected to the first liquid outlet 122. The plurality of flow spoilers 10 are spaced apart from the plurality of heat exchange tubes 20, and the flow spoilers 10 are arranged perpendicular to the heat exchange tubes 20. The side wall of the housing 100 is provided with two openings, and the water-collecting mechanism 130 and the discharge mechanism 140 are respectively disposed at the two openings. The first end of the water-collecting mechanism 130 is rotatably connected to the housing 100, and the second end of the water-collecting mechanism 130 is a free end. Under the impact of seawater, the second end of the water-collecting mechanism 130 can move away from the housing 100 to allow seawater to enter the housing 100. The first end of the discharge mechanism 140 is rotatably connected to the housing 100, and the second end of the discharge mechanism 140 is a free end. Under the weight of seawater, the second end of the discharge mechanism 140 can move away from the housing 100 to allow seawater after heat exchange to be discharged from the housing 100. The rotation direction of the water-collecting mechanism 130 is opposite to that of the discharge mechanism 140.

[0029] Specifically, an inlet tube sheet 110 and an outlet tube sheet 120 are provided at both ends of the shell 100. The inlet tube sheet 110 is provided with a plurality of first through-holes along its height, each of which communicates with the first end of a heat exchange tube 20. The outlet tube sheet 120 is provided with a plurality of second through-holes along its height, each of which communicates with the second end of a heat exchange tube 20. An inlet header 111 is connected to the inlet tube sheet 110 and is provided with a first liquid inlet 112. An outlet header 121 is connected to the outlet tube sheet 120 and is provided with a first liquid outlet 122. A higher-temperature fluid flows from the first liquid inlet 112 through the inlet header 111 and the inlet tube sheet 110, enters each heat exchange tube 20, then flows through the outlet tube sheet 120 and the outlet header 121 before being discharged through the first liquid outlet 122.

[0030] Seawater enters the shell side of the housing 100 through the water-collecting mechanism 130, exchanges heat with the fluid in the tube side of the heat exchange tube 20, and is then discharged by the discharge mechanism 140. Multiple spoiler rods 10 are arranged in an array, and the multiple spoiler rods 10 are divided into multiple groups. Each group includes multiple parallel spoiler rods 10, and the spoiler rods 10 in two adjacent groups are arranged perpendicular to each other. Each spoiler rod 10 is arranged perpendicular to the heat exchange tube 20. During the heat exchange process, the provision of the spoiler rods 10 causes the seawater to generate local vortices on the surface of the heat exchange tube 20, thereby enhancing the heat transfer effect of the heat exchange tube 20 and improving the heat exchange capacity of the modular longitudinal flow conformal cooler.

[0031] Furthermore, two openings are provided on the side wall of the shell 100. When the ship is in a stationary state, the second end of the water-collecting mechanism 130 overlaps with the shell 100, and the second end of the discharge mechanism 140 also overlaps with the shell 100, so that both openings are in a closed state.

[0032] During the ship's movement, seawater impacts the water-holding mechanism 130. Under the impact of seawater, the second end of the water-holding mechanism 130 rotates relative to the first end, causing the opening to be open, forming a seawater inlet. Seawater enters the shell side of the shell 100 and exchanges heat with the fluid in the heat exchange tube 20. The seawater then relies on its own weight to cause the second end of the discharge mechanism 140 to rotate relative to the first end, thereby causing the other opening to be open as well, forming a seawater outlet, and discharging the seawater that has undergone heat exchange. When the ship stops sailing, the water-holding mechanism 130 automatically resets, and the second end of the water-holding mechanism 130 overlaps the outer wall of the shell 100, closing the opening where the water-holding mechanism 130 is located. At the same time, when the seawater in the shell side of the shell 100 is basically drained, the discharge mechanism 140 automatically resets, closing the opening where the discharge mechanism 140 is located.

[0033] The modular longitudinal flow conformal cooler provided in an embodiment of the present invention, by providing a water-holding mechanism and a discharge mechanism, can utilize the impact force of seawater to automatically open the water-holding mechanism, allowing seawater to automatically enter the shell side of the shell. Then, under the action of the seawater's own weight, the discharge mechanism is automatically opened, thereby discharging the seawater after heat exchange. This avoids the need for a pump in the conformal cooling system, reduces the power consumption of the conformal cooling system, and also avoids the noise generated by the pump during operation, which may cause intrusion to the user.

[0034] like Figure 1 As shown, in an embodiment of the present invention, the water-catching mechanism 130 includes: a first elastic member and a water-catching plate. The first elastic member is disposed at an opening, a first end of the first elastic member is connected to the housing 100, a first end of the water-catching plate is connected to a second end of the first elastic member, and the second end of the water-catching plate is a free end. When the impact force of seawater is greater than the elastic force of the first elastic member, the water-catching plate can move away from the housing 100. When the impact force of seawater is less than the elastic force of the first elastic member, the water-catching plate can move toward the housing 100.

[0035] Specifically, when the vessel is stationary, the second end of the water-retaining plate overlaps the outer wall of the housing 100, thereby sealing the opening. During navigation, when the impact force of seawater exceeds the elastic force of the first elastic member, the second end of the water-retaining plate moves away from the housing 100, thereby opening the opening and allowing seawater to enter the housing 100 through the opening. When the vessel stops, the impact force on the water-retaining plate decreases. When the impact force of seawater becomes less than the elastic force of the first elastic member, the first elastic member returns to its original position, driving the second end of the water-retaining plate toward the housing 100.

[0036] Furthermore, the discharge mechanism 140 includes a second elastic member and a drain plate. The second elastic member is disposed at the other opening, with a first end of the second elastic member connected to the housing 100, and a first end of the drain plate connected to a second end of the second elastic member. The second end of the drain plate is a free end. When the weight of the seawater is greater than the elastic force of the second elastic member, the drain plate can move away from the housing 100. When the weight of the seawater is less than the elastic force of the second elastic member, the drain plate moves toward the housing 100. The movement direction of the drain plate is opposite to that of the water retaining plate.

[0037] Specifically, seawater undergoing heat exchange in the shell side flows to the discharge mechanism 140. When the weight of the seawater exceeds the elastic force of the second elastic member, the second end of the drain plate moves away from the outer wall of the shell 100, thereby opening the opening there and allowing the seawater to be discharged. When the ship is stopped and the shell side seawater is substantially drained, the weight of the seawater becomes less than the elastic force of the second elastic member, causing the second elastic member to return to its original position, driving the drain plate toward the shell 100.

[0038] Furthermore, in this embodiment, the movement direction of the water-retaining plate when it is away from the shell 100 is opposite to the movement direction of the drain plate when it is away from the shell 100; the movement direction of the water-retaining plate when it is close to the shell 100 is also opposite to the movement direction of the drain plate when it is close to the shell 100.

[0039] like Figure 3 As shown, in an embodiment of the present invention, the spoiler rod 10 has a first side and a second side relative to each other, and the side wall between the first side and the second side is used to connect with the heat exchange tube 20, wherein the first side is the upstream side, the first side is a circular arc surface, and the width dimension of the spoiler rod 10 is greater than the thickness dimension of the spoiler rod 10.

[0040] Specifically, in a longitudinal flow heat exchanger, a higher-temperature fluid flows in the heat exchange tube 20. After the seawater enters the heat exchanger shell, it flows along the length of the heat exchange tube 20. Each heat exchange tube 20 is provided with a plurality of deflection rods along its length. In the prior art, the deflection rods are circular straight tubes, which have a large contact area with the seawater and a large resistance, thereby reducing the heat exchange efficiency of the heat exchanger.

[0041] In this embodiment, the first side of the spoiler rod 10 is the upstream side, and the second side is the downstream side. The first side of the spoiler rod 10 is arc-shaped, which can reduce the contact area between the upstream side and the seawater, thereby reducing the flow resistance of the seawater; and the width of the spoiler rod 10 is smaller than the thickness of the spoiler rod 10, so that the cross-section of the spoiler rod 10 is flat, so as to reduce the contact area between the entire spoiler rod 10 and the seawater, thereby reducing the flow resistance.

[0042] Optionally, in an embodiment of the present invention, the cross-sectional shape of the spoiler rod 10 may be a teardrop shape, an elliptical shape, a rugby ball shape, or the like.

[0043] Furthermore, in the prior art, the deflector rods are typically circular straight tubes. After seawater passes through the circular straight tubes, a cylindrical turbulence effect is easily generated at the rear of the circular straight tubes, inducing vibration of the deflector rods, which in turn causes vibration friction between the deflector rods and the heat exchange tubes 20, which can easily damage the heat exchanger. By reducing the thickness of the deflector rods 10 and increasing the width thereof, the cylindrical turbulence effect generated by seawater at the rear of the deflector rods 10 can be avoided, thereby preventing the deflector rods 10 from vibrating due to the cylindrical turbulence effect. This reduces the vibration friction between the deflector rods 10 and the heat exchange tubes 20, thereby increasing the service life of the heat exchanger.

[0044] The modular longitudinal flow conformal cooler provided by the embodiment of the present invention can reduce the contact area between the spoiler rod and the fluid while ensuring the strength of the spoiler rod by setting the flow-facing side of the spoiler rod to a circular arc surface and making the width dimension of the spoiler rod larger than the thickness dimension of the spoiler rod, thereby reducing the flow resistance of the fluid and improving the heat exchange efficiency of the modular longitudinal flow conformal cooler; at the same time, making the width dimension of the spoiler rod larger than the thickness dimension of the spoiler rod can also avoid the generation of cylindrical spoiler effect, avoid the vibration of the spoiler rod caused by the cylindrical spoiler effect, and thus avoid the generation of vibration friction between the spoiler rod and the heat exchange tube, thereby improving the service life of the modular longitudinal flow conformal cooler.

[0045] like Figure 3 As shown, in an embodiment of the present invention, the width of the second side of the spoiler bar 10 is smaller than the width of the first side. Specifically, after the seawater passes through the first side of the spoiler bar 10, the contact area between the seawater and the second side of the spoiler bar 10 is smaller, thereby further reducing the resistance of the seawater when flowing.

[0046] Optionally, in an embodiment of the present invention, the cross-section of the spoiler rod 10 is in the shape of a water drop.

[0047] like Figure 3As shown, in an embodiment of the present invention, the spoiler bar 10 includes a first body 11, a second body 12 and a third body 13 connected in sequence, wherein the cross-sectional shape of the first body 11 is an arc shape, the cross-sectional shape of the second body 12 is a rectangle, and the distance between the two opposite sides connected to the third body 13 and the second body 12 gradually decreases to form a tapered shape.

[0048] Specifically, in the prior art, the deflector rod is a circular straight tube, and its connection with the heat exchange tube 20 is a point-to-point connection. Under the impact of seawater and the effect of cylindrical turbulence, the deflector rod is prone to vibrate, which in turn causes vibration friction between the deflector rod and the heat exchange tube 20, causing damage to the conformal cooler structure.

[0049] In this embodiment, the cross-sectional shape of the second body 12 is rectangular, and the connection between the second body 12 and the heat exchange tube 20 is a line-to-line connection, thereby increasing the contact area between the spoiler rod 10 and the heat exchange tube 20 to suppress vibration friction.

[0050] Further, in the present embodiment, the cross-sectional shape of the first body 11 can be semicircular, the cross-sectional shape of the second body 12 is rectangular, the width of the rectangle is equal to the diameter of the semicircle, and the cross-sectional shape of the third body 13 can be an isosceles triangle, the two waists of the isosceles triangle are respectively connected to the two long sides of the rectangle, so that the cross-sectional shape of the spoiler bar 10 is similar to an elongated teardrop shape, thereby avoiding the generation of a cylindrical spoiler effect at the rear of the spoiler bar 10, thereby avoiding the vibration of the spoiler bar 10 caused by the cylindrical spoiler effect. In the present embodiment, the sum of the lengths of the first body 11, the second body 12, and the third body 13 is greater than the width of the second body 12, thereby reducing the contact area between the seawater and the spoiler bar 10, thereby reducing the flow resistance of the seawater.

[0051] like Figure 4 As shown, in one embodiment of the present invention, the first end of the first body 11 of the spoiler bar 10 is connected to the second body 12 , and the second end of the first body 11 is provided with a plurality of protrusions 1101 .

[0052] Specifically, the plurality of protrusions 1101 provided on the flow-incident side of the spoiler bar 10 can play a role in destroying boundary layer adhesion and reducing the flow-incident side resistance of the spoiler bar 10. Furthermore, the cross-sectional shape of the protrusions 1101 can be various shapes, such as diamond, circle, etc.

[0053] like Figure 5 As shown, in the embodiment of the present invention, the first end of the third body 13 is connected to the second body 12 , and the end of the second end of the third body 13 is provided with a sawtooth structure 131 .

[0054] Specifically, in the embodiment described above, the distance between the two edges connecting the third body 13 and the second body 12 gradually decreases to form a tip, and the tip is provided with a serrated structure 131. The serrated structure 131 can reduce vortex shedding resistance and suppress vortex shedding excitation, thereby enhancing heat exchange capacity.

[0055] like Figure 5 As shown, in an embodiment of the present invention, angle wing structures 132 are provided on opposite sides of the third body 13. The angle wing structure 132 has a first surface facing the incoming flow, and the angle formed between the first surface and the surface of the second body 12 is an acute angle.

[0056] Specifically, in this embodiment, the distance between the two opposite side surfaces of the third body 13 gradually decreases, so that the two opposite side surfaces of the third body 13 form an inclined surface, and multiple angle wing structures 132 are provided on the two inclined surfaces. An angle is formed between the angle wing structure 132 and the inclined surface, so that when seawater passes through the angle wing structure 132, a flow vortex is formed around the angle wing structure 132, thereby increasing the contact area between the seawater and the heat exchange tube, thereby improving the heat exchange capacity.

[0057] Optionally, the angle wing structure 132 may be a rectangular block or a triangular block. When the angle wing structure 132 is connected to the third body 13 , it should be ensured that an angle is formed between the two, and the angle is an acute angle.

[0058] Further, if Figure 5 As shown, in an embodiment of the present invention, the corner wing structure 132 also has a second surface and a third surface relative to each other, and the second surface and the third surface are respectively located on both sides of the first surface, and the distance between the second surface and the third surface increases along the direction away from the surface of the second body 12.

[0059] Specifically, in this embodiment, the wing structure 132 is a pentahedron. Its surface facing the incoming flow is the first surface, the two side surfaces on either side of the first surface are the second and third surfaces, the top surface is the fourth surface, and the back surface opposite the first surface is the fifth surface. The fourth surface is an isosceles triangle, and the second and third surfaces are inclined relative to the surface of the second body 12. That is, both the second and third surfaces are inclined, and the angle between the second surface and the surface of the second body 12 is acute, as is the angle between the third surface and the surface of the second body 12. When fluid passes through the wing structure 132, a streamwise vortex is easily formed around the wing structure 132, thereby increasing the contact area between the seawater and the heat exchange tubes and improving heat exchange capacity.

[0060] Furthermore, multiple spoiler rods 10 are arranged in an array. Along the width direction of the shell 100, the spoiler rods 10 and the heat exchange tubes 20 are alternately arranged. Along the length direction of the shell 100, multiple spoiler rods 10 are evenly spaced on the outer wall of each heat exchange tube 20.

[0061] like Figure 2 As shown, in one embodiment of the present invention, the modular longitudinal flow conformal cooler further includes a plurality of spoiler rings 30, which are arranged in the shell 100 and are sequentially sleeved on the outside of the plurality of heat exchange tubes 20, and the spoiler rings 30 are used to fix the spoiler rod 10.

[0062] Specifically, in this embodiment, the number of spoiler rings 30 is the same as the number of groups of spoiler rods. Each spoiler ring 30 is used to fix multiple spoiler rods 10 in a group, and both ends of each spoiler rod 10 are connected to the inner wall of a spoiler ring 30.

[0063] like Figure 6 and Figure 7 As shown, an embodiment of the present invention further provides a conformal cooling system, comprising a plurality of modular longitudinal flow conformal coolers, wherein the plurality of modular longitudinal flow conformal coolers are arranged side by side on both sides of the ship, the first liquid inlet 112 of each modular longitudinal flow conformal cooler is connected to a liquid inlet pipe 200, and the first liquid outlet 122 of each modular longitudinal flow conformal cooler is connected to a liquid outlet pipe 300.

[0064] Specifically, multiple modular longitudinal conformal coolers are installed on both sides of the ship to utilize the side space. Multiple modular longitudinal conformal coolers on each side are arranged side by side. Each modular longitudinal conformal cooler introduces a higher-temperature fluid into the tube side of the modular longitudinal conformal cooler through the liquid inlet pipe 200. Seawater is introduced into the shell side through the water scoop mechanism 130. After the seawater exchanges heat with the fluid, the seawater is discharged from the shell 100 through the discharge mechanism 140. The cooled fluid enters other heat exchangers through the liquid outlet pipe 300 to dissipate heat for the equipment on the ship.

[0065] The conformal cooling system provided by an embodiment of the present invention, by providing a plurality of modular longitudinal-flow conformal coolers, can utilize the impact force of seawater to automatically cause seawater to enter the shell side of the shell, and then automatically discharge the seawater after heat exchange under the action of its own weight. This avoids the need for a pump in the conformal cooling system, reduces the power consumption of the conformal cooling system, and also avoids the noise generated by the operation of the pump, which may cause intrusion to the user.

[0066] 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. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
