[0002] There are a large number of impact-resistant seawater coolers in the ship power system. In the vast majority of coolers, the inside of the heat exchange tubes is high-pressure seawater, and the outside is low-pressure fresh water. Since the seawater pressure inside the heat exchange tubes of the cooler directly acts on the tube walls, relatively high requirements are put forward for the structural strength of the heat exchange tubes. Existing ordinary round tubes can only strengthen the structure by increasing the wall thickness of the heat exchange tubes, which leads to an increase in the thermal resistance of the heat exchange tube walls, reducing the heat exchange capacity. At the same time, it also increases the volume of the impact-resistant seawater cooler, resulting in waste of space. Summary of the Invention

Detailed implementation manners

[0021] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts belong to the scope of protection of the present invention.

[0022] The terms "first" and "second" in the description and claims of the present invention may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0023] Next, with reference to Figures 1 - 3 the impact-resistant seawater cooler and the impact-resistant seawater cooling system of the present invention will be described.

[0024] As Figure 1 shown, in an embodiment of the present invention, the impact-resistant seawater cooler includes: a housing 100 and a plurality of flexible heat exchange tubes 10. The housing 100 is a flexible housing, which can extend along its own length direction under the impact of seawater. The two ends of the housing 100 extending along the length direction are respectively provided with a first liquid inlet 101 and a first liquid outlet 102. Among them, the first liquid inlet 101 is used to inject seawater, and the first liquid outlet 102 is used to discharge seawater. A plurality of flexible heat exchange tubes 10 are arranged in the housing 100. The inlet of each flexible heat exchange tube 10 is communicated with the first liquid inlet 101, and the outlet of each flexible heat exchange tube 10 is communicated with the first liquid outlet 102. Among them, each flexible heat exchange tube 10 includes a plurality of sequentially connected bending parts. Under the impact of seawater, the flexible heat exchange tube 10 can extend along its own length direction.

[0025] Specifically, during the progress of the ship, the impact of ocean currents, surges, etc. will act on the impact-resistant seawater cooler. In the prior art, the heat exchange tubes of the seawater cooler are rigid straight tubes, and the rigid straight tubes are rigidly connected to the shell of the impact-resistant seawater cooler. Under the impact of seawater, the rigid straight tubes will not undergo elastic deformation, which is extremely likely to cause damage to the structure of the seawater cooler.

[0026] In this embodiment, seawater enters each flexible heat exchange tube 10 from the first liquid inlet 101. Since the shell 100 is a flexible shell, under the impact of seawater, the shell 100 can extend along its own length direction, thereby absorbing the impact energy of the seawater to reduce the impact force of the seawater on the shell 100. When the seawater enters the flexible heat exchange tube 10, since the heat exchange tube is a flexible heat exchange tube 10 and has a plurality of bending parts, under the impact of seawater, the bending parts are stressed and extended, so that the flexible heat exchange tube 10 can extend along its own length direction. When the flexible heat exchange tube 10 extends along its own length direction, the shell 100 can also extend along its own length direction, so as not to impose constraints on the extension of the flexible heat exchange tube 10. When the flexible heat exchange tube 10 and the shell 100 extend along their respective length directions, the shell 100 and the flexible heat exchange tube 10 can absorb the impact energy of the seawater, thereby reducing the impact of the seawater on the shell 100 and the flexible heat exchange tube 10, improving the strength of the shell 100 and the flexible heat exchange tube 10, and avoiding damage to the structure of the impact-resistant seawater cooler caused by seawater.

[0027] Further, in this embodiment, at least part of the shell 100 has flexibility, so that the shell 100 can extend along its own length direction under the impact of seawater.

[0028] Further, in this embodiment, the flexible heat exchange tube 10 can be a spiral flexible heat exchange tube or a corrugated flexible heat exchange tube.

[0029] The impact-resistant seawater cooler provided by the embodiment of the present invention, by setting the shell as a flexible shell and the heat exchange tube as a flexible heat exchange tube, and the flexible heat exchange tube includes a plurality of bending parts. When impacted by seawater, the bending parts are extended, so that the flexible heat exchange tube extends along its own length direction to absorb the impact energy of the seawater. Thus, without increasing the wall thickness of the heat exchange tube, the strength of the heat exchange tube can be ensured, the impact resistance of the seawater cooler is improved, and the problems of poor heat exchange capacity of the heat exchange tube and large volume of the cooler caused by increasing the wall thickness of the heat exchange tube are avoided.

[0030] Optionally, in the embodiment of the present invention, the flexible heat exchange tube 10 is a spiral flexible heat exchange tube or a corrugated flexible heat exchange tube.

[0031] Specifically, in the prior art, the heat exchange tubes are mostly circular straight tubes and rigid tubes. Under the impact of seawater, the rigid straight tubes will not extend along their own length direction, and thus cannot absorb the impact energy of seawater. Therefore, when the wall thickness of the heat exchange tubes is relatively thin, they are extremely likely to be damaged, and it is necessary to increase the wall thickness of the heat exchange tubes to improve their strength. After increasing the wall thickness of the heat exchange tubes, their heat exchange capacity will correspondingly decrease to a certain extent.

[0032] In this embodiment, the flexible heat exchange tube 10 is designed as a spiral heat exchange tube or a corrugated heat exchange tube, so that it has multiple bending parts. When seawater enters the flexible heat exchange tube 10, under the impact of seawater, the bending parts extend, and the flexible heat exchange tube 10 extends along its own length direction, thereby being able to absorb the impact energy of seawater, reducing the impact force of seawater on the flexible heat exchange tube 10, and further improving the strength of the flexible heat exchange tube 10, enabling it to improve the strength without increasing the wall thickness, ensuring the heat exchange capacity of the flexible heat exchange tube 10, and improving the cooling capacity of the impact-resistant seawater cooler.

[0033] As Figure 2 shown, in an embodiment of the present invention, the impact-resistant seawater cooler further includes a plurality of first fins 11. A plurality of first fins 11 are provided on the outer wall of each flexible heat exchange tube 10.

[0034] Specifically, providing a plurality of first fins 11 on the outer wall of the flexible heat exchange tube 10 can increase the strength of the flexible heat exchange tube 10, improve the pressure-bearing capacity of the flexible heat exchange tube 10, ensure its structural integrity under a large pressure difference, and at the same time can play a role in inducing the fluid around the surface of the flexible heat exchange tube 10, constituting an extended surface, increasing the heat transfer area, strengthening the heat exchange capacity of the impact-resistant seawater cooler, and reducing the volume of the impact-resistant seawater cooler.

[0035] Optionally, the shape of the first fin 11 can be various shapes such as a rectangle or a triangle.

[0036] Further, in this embodiment, one end of each first fin 11 away from the flexible heat exchange tube 10 is a tip.

[0037] Specifically, in this embodiment, each first fin 11 is a triangular structure, and the side of the triangular structure is connected to the flexible heat exchange tube 10, thereby playing a role in enhancing the strength of the flexible heat exchange tube 10. One end of the first fin 11 away from the flexible heat exchange tube 10 is a tip, and the tip can reduce the occupancy rate of the space inside the housing 100 by the first fin 11, facilitating the arrangement of the first fins 11, and at the same time can reduce the resistance to the medium entering the housing 100, facilitating the flow of the medium inside the housing 100 to improve the heat exchange capacity between the medium and the seawater inside the flexible heat exchange tube 10.

[0038] As Figure 2As shown, in one embodiment of the present invention, the impact-resistant seawater cooler further comprises a plurality of second fins 12. The inner wall of each flexible heat exchange tube 10 is provided with a plurality of second fins 12, and the second fins 12 and the first fins 11 are staggered.

[0039] Specifically, a plurality of second fins 12 are arranged on the inner wall of the flexible heat exchange tube 10, which can increase the strength of the flexible heat exchange tube 10, improve the pressure bearing capacity of the flexible heat exchange tube 10, and ensure its structural integrity under large pressure differences. At the same time, it can induce flow around the fluid near the surface of the flexible heat exchange tube 10, constitute an extended surface, increase the heat transfer area, enhance the heat exchange capacity of the impact-resistant seawater cooler, and reduce the volume of the impact-resistant seawater cooler.

[0040] A second fin is arranged on the inner wall of the flexible heat exchange tube 10, and the second fin 12 is staggered with the first fin 11, so as to compensate for the position where the pressure bearing capacity of the tube wall of the flexible heat exchange tube 10 is poor, so that the pressure bearing capacity of the flexible heat exchange tube 10 is uniform, and it is avoided that a certain position of the flexible heat exchange tube 10 is poor in strength under the impact of seawater and local damage occurs.

[0041] Furthermore, in the embodiment of the present invention, one end of each second fin 12 away from the flexible heat exchange tube 10 is pointed.

[0042] Specifically, in this embodiment, each second fin 12 is a triangular structure, and the side of the triangular structure is connected to the flexible heat exchange tube 10, so as to enhance the strength of the flexible heat exchange tube 10. The end of the second fin 12 away from the flexible heat exchange tube 10 is a tip, which can reduce the resistance to the seawater entering the flexible heat exchange tube 10, facilitate the flow of seawater in the flexible heat exchange tube 10, and improve the heat exchange capacity between the seawater and the medium in the shell 100. Furthermore, since there are many marine organisms in the seawater, setting one end of the second fin 12 as a tip can reduce the adhesion of the marine organisms on the second fin 12, prevent the marine organisms from growing in the flexible heat exchange tube 10, and then block the seawater flow channel, thereby reducing the heat exchange capacity of the impact-resistant seawater cooler.

[0043] like Figure 1 As shown, in an embodiment of the present invention, the shell 100 includes a first shell 110, a flexible tube 120 and a second shell 130. The first shell 110 is provided with a first liquid inlet 101, and the second shell 130 is provided with a first liquid outlet 102. The first shell 110 and the second shell 130 are connected through the flexible tube 120 so that the shell 100 can extend along its own length direction under the impact of seawater.

[0044] Specifically, the housing 100 is divided into a first housing 110 and a second housing 130. The two housings are connected by a flexible connection pipe 120, making the housing 100 flexible. When the flexible heat exchange tube 10 extends along its own length direction, the housing 100 can also extend along its own length direction to perform displacement compensation and absorb the impact energy of seawater, so as to prevent the housing 100 from being damaged under the impact of seawater.

[0045] Furthermore, a part of the housing 100 is set as the flexible connection pipe 120, and the first housing 110 and the second housing 130 are of rigid structures. Compared with the housing 100 adopting a flexible structure as a whole, the strength of the housing 100 is increased.

[0046] As Figure 1 shown, in the embodiment of the present invention, the impact-resistant seawater cooler further includes: a liquid inlet header 103 and a liquid outlet header 104. The liquid inlet header 103 and the liquid outlet header 104 are respectively arranged at both ends of the housing 100 and communicated with the housing 100. Among them, the liquid inlet header 103 is provided with a first liquid inlet 101, and the liquid outlet header 104 is provided with a first liquid outlet 102.

[0047] Specifically, seawater enters the liquid inlet header 103 from the first liquid inlet 101, and then enters each flexible heat exchange tube 10. After flowing through the liquid outlet header 104, it is discharged from the first liquid outlet 102.

[0048] Furthermore, as Figure 1 shown, in the embodiment of the present invention, the impact-resistant seawater cooler further includes a second liquid inlet 105 and a second liquid outlet 106. The second liquid inlet 105 is arranged on the first housing 110, and the second liquid inlet 105 is used for injecting a medium. The second liquid outlet 106 is arranged on the second housing 130, and the second liquid outlet 106 is used for discharging the medium.

[0049] Specifically, seawater enters the flexible heat exchange tube 10 from the first liquid inlet 101, and the medium with a higher temperature enters the housing 100 from the second liquid inlet 105. After the medium with a higher temperature exchanges heat with the seawater, the medium is discharged from the second liquid outlet 106, and the seawater is discharged from the first liquid outlet 102.

[0050] As Figure 3 shown, the embodiment of the present invention also provides an impact-resistant seawater cooling system, which includes a pump 200, a pipeline 300 and an impact-resistant seawater cooler. The pipeline 300 is connected to the first liquid inlet 101 of the impact-resistant seawater cooler, and the pump 200 is arranged on the pipeline 300.

[0051] Specifically, the pump 200 and the impact-resistant seawater cooler are elastically mounted on the hull to prevent damage to the pump 200 and the impact-resistant seawater cooler under the impact of seawater. The pump 200 pumps seawater into the flexible heat exchange tube 10 of the impact-resistant seawater cooler. After the seawater exchanges heat with the medium at a higher temperature in the shell 100 of the impact-resistant seawater cooler, the seawater that absorbs heat is discharged into the sea through the first liquid outlet 102 of the impact-resistant seawater cooler. In this embodiment, when the seawater enters the shell 100, under the impact of the seawater, the flexible heat exchange tube 10 and the shell 100 undergo elastic deformation, and both extend along their respective length directions to absorb the impact energy of the seawater and prevent damage to the shell 100 and the flexible heat exchange tube 10. Further, when the shell 100 and the flexible heat exchange tube 10 extend along their respective length directions, the noise generated by the vibration during the operation of the pump 200 can be effectively suppressed, thereby reducing the noise generated during the operation of the impact-resistant seawater cooling system.

[0052] In the impact-resistant seawater cooling system provided by the embodiment of the present invention, by providing the impact-resistant seawater cooler, the impact energy of the seawater can be absorbed. Furthermore, without increasing the wall thickness of the heat exchange tube, the strength of the heat exchange tube can be ensured, solving the problems in the prior art that the heat exchange capacity of the heat exchange tube decreases and the volume of the impact-resistant seawater cooler increases due to the increase in the wall thickness of the heat exchange tube. At the same time, when the shell and the flexible heat exchange tube extend along their respective length directions, the noise generated by the vibration during the operation of the pump can be effectively suppressed, reducing the noise of the impact-resistant seawater cooling system.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. However, these modifications or replacements 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.
