Description

Title of the invention: Heat dissipation device for underwater equipment Technical field

[0001] The present application relates to the field of heat dissipation technology, and in particular relates to a heat dissipation device for underwater equipment. TECHNICAL CONTEXT

[0002] When an underwater communication system realizes long-distance communication, it is affected by the underwater terrains of different regions, and the laying methods of underwater photoelectric cables and equipment vary depending on the region. For example, underwater photoelectric cables and equipment located in shallow areas must be buried at least 3 m below the seabed to reduce the impacts of human activities and environmental organisms on the equipment and cables, while, in deep areas, underwater photoelectric cables and equipment can be laid directly on the surface of the seabed since there are fewer human activities and environmental organisms.

[0003] Due to the accuracy of the underwater communication system and the required design life, underwater equipment has strict requirements on the working temperature range, which is often between 0 and 35°C. The water temperature in the deep zone is generally about 4°C, and even if the underwater equipment generates heat during operation, the working temperature of the underwater equipment can be lowered by seawater.

[0004] However, in shallow areas, the underwater equipment is buried in sediment, and the envelopment of sediment will reduce the heat dissipation efficiency of the underwater equipment. In addition, the surface seawater temperature varies with the seasons, and the heat dissipation efficiency of the underwater equipment is reduced when the seawater temperature is high, thereby affecting the normal operation of the underwater equipment. DISCLOSURE OF THE INVENTION

[0005] The present application provides a heat dissipation device for underwater equipment to solve the problems of low heat dissipation efficiency of underwater equipment located in a shallow area for an underwater communication system, which affects the normal operation of the underwater equipment.

[0006] According to an embodiment of the present application, a heat dissipation device for underwater equipment is provided. This device is usable in underwater equipment of an underwater communication system and comprises:

[0007] - a heat dissipation shell, the heat dissipation shell being arranged around the exterior of underwater equipment, the heat dissipation shell comprising an outer wall shell body, the outer wall shell body having a cylindrical structure, the cross-sectional diameter of the outer wall shell body being greater than the cross-sectional diameter of the shell of the underwater equipment, and the outer wall shell body and the underwater equipment being arranged coaxially;

[0009] In this way, by providing the heat dissipation shell and the water permeable component around the exterior of the underwater equipment, the underwater equipment can be filled with liquid in the heat dissipation shell during construction of the underwater equipment, thereby increasing the heat dissipation area of ​​the underwater equipment and the heat conduction efficiency through the cooperation between the liquid and the shell body, thereby increasing the heat dissipation efficiency of the underwater equipment during operation and improving the operation stability of the underwater communication system.

[0010] In one possible embodiment, the heat dissipation shell further comprises a fixing bracket, disposed between the underwater equipment shell and the outer wall shell body and configured to support the heat dissipation chamber.

[0011] In one possible embodiment, the mounting bracket comprises at least one annular sheet which comprises an inner annular surface and an outer annular surface, the annular sheet and the outer wall shell body being arranged coaxially, the inner annular surface bearing against the hull of the underwater equipment and the outer annular surface bearing against the outer wall shell body. In this way, the arrangement of the annular sheet between the underwater equipment hull and the outer wall hull body can support the heat dissipation chamber formed by the heat dissipation shell and the water permeable component, thereby reducing the risk of structural deformation.

In this way, the arrangement of the plurality of annular sheets allows the heat dissipation hull to be supported, thereby reducing the risk of structural deformation under pressure.

[0013] In one possible embodiment, the annular sheet has a plurality of water-permeable holes arranged in an array, and the diameter of the water-permeable holes is less than or equal to the diameter of the first water inlet hole. In this way, once the heat dissipation chamber is divided into several chamber segments by the plurality of annular sheets, the flow of the liquid can be realized through the water-permeable holes, thereby increasing the heat dissipation efficiency of the underwater equipment by using the heat dissipation device for underwater equipment.

[0014] In one possible embodiment, a friction element is provided on the annular sheet, the friction element is provided between the inner annular surface and the hull of the underwater equipment, and the friction element serves to increase the friction force between the annular sheet and the underwater equipment. The provision of the friction element increases the friction force between the annular sheet and the underwater equipment and thus prevents the heat dissipation hull from slipping or coming loose.

[0015] In one possible embodiment, the outer wall shell body is provided with a fixing groove, and the fixing groove fits without clearance to the annular sheet to arrange the annular sheet on the outer wall shell body. In this way, the fit to the outer wall shell body allows the annular sheet to be fixed, which increases the fixing strength of the annular sheet, thereby improving the structural strength of the heat dissipation device for underwater equipment.

[0017] In one possible embodiment, the heat dissipation shell and the water permeable component are made of metal. The heat dissipation shell and the water permeable component made of metal can increase the structural strength of the heat dissipation device for underwater equipment, and at the same time, the metal has good thermal conductivity to increase the heat dissipation efficiency of the underwater equipment.

[0018] In one possible embodiment, the heat dissipation shell has a plurality of second water-permeable holes arranged in an array, and the diameter of the second water-permeable holes is less than or equal to the diameter of the first water inlet holes. The arrangement of the second water-permeable holes on the heat dissipation shell makes it possible to increase the filling speed of water in the heat dissipation chamber, thereby avoiding the problem of insufficient filling of water in the heat dissipation chamber.

[0019] In one possible embodiment, the diameter of the first water inlet holes is less than 5 mm and greater than 1 mm. In this way, the situation in which a large amount of sediment enters the heat dissipation chamber during operation of the underwater equipment can be reduced and the heat dissipation efficiency of the underwater equipment can be increased.

[0032] The technical solutions of the present invention will be described below in detail with reference to the embodiments, which are presented only as non-limiting examples.

[0033] The terms "first", "second" are illustrative, and cannot be considered as indicating or implying a degree of relative importance or a number of technical characteristics indicated. Thus, features with the words "first" or "second" can be considered as indicating or implying one or more characteristics. In the description herein invention, unless otherwise indicated, the term "several" means two or more. In addition, the terms "assembly", "connect one to the other", and "connect" should be understood in a broad sense. For example, it may be a fixed connection or a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection via an intermediate means, and it may be an internal communication between two components. For those skilled in the art, the above terms may be understood according to the specific situations in the embodiments of the present invention.

[0034] An underwater communication system is a system placed on the seabed or lakebed to perform long-distance data communication. For illustration purposes, underwater communication systems may include a submarine cable communication system.

[0035] When an underwater communication system realizes a long-distance communication process, it is affected by the underwater terrains of different regions, and the laying methods of underwater photoelectric cables and equipment vary depending on the region. As shown in [Fig.l], underwater photoelectric cables and equipment located in shallow areas should be buried at least 3 m below the seabed to reduce impacts of human activities and environmental organisms on the equipment and cables, while underwater photoelectric cables and equipment located in deep areas can be laid directly on the surface of the deep seabed since there are fewer human activities and environmental organisms in deep areas.

[0036] Due to the accuracy of the underwater communication system and the required design life, underwater equipment has strict requirements on the working temperature range. In some embodiments, the working temperature of the underwater equipment is between 0 and 35°C. The water temperature in the deep zone is generally about 4°C, and even if heat is generated during operation of the underwater equipment, the working temperature of the underwater equipment can be lowered by the seawater dissipating the heat from the underwater equipment.

[0037] However, in shallow areas, the underwater equipment is buried in sediment, and the envelopment of sediment will reduce the heat dissipation efficiency of the underwater equipment. In addition, the surface seawater temperature varies with the seasons, and the heat dissipation efficiency of the underwater equipment is reduced when the seawater temperature is high, thereby affecting the normal operation of the underwater equipment.

[0038] To solve the problems of low heat dissipation efficiency of underwater equipment located in a shallow area for an underwater communication system, which affect the normal operation of the underwater equipment, a heat dissipation device for underwater equipment is provided in the embodiments of the present application, usable in underwater equipment of an underwater communication system. As shown in [Fig.2], the heat dissipation device comprises a heat dissipation shell 100 and a water-permeable component 200, the heat dissipation shell 100 being sheathed outside the underwater equipment.

[0039] The heat dissipation shell 100 comprises an outer wall shell body 110, the outer wall shell body 110 has a cylindrical structure, the cross-sectional diameter of the outer wall shell body 110 is larger than the cross-sectional diameter of the underwater equipment wrapped by the heat dissipation shell 100, and the outer wall shell body 110 and the underwater equipment are coaxially arranged, so that the heat generated by the underwater equipment during operation can be dissipated through the heat dissipation shell and the medium contained in the heat dissipation shell.

[0040] It should be noted that the underwater equipment in the embodiments of the present application may be an optical repeater RPT (repeater) or other equipment. During long-distance communication transmission, signals are lost in the cables. Therefore, the RPT having the function of signal amplification and relaying must be arranged in the cables at a certain interval. The cable length between two successive RPTs may be 50 km, 70 km, 100 km to realize long-distance transmission of signals, this cable length between the two RPTs is not specifically limited within the scope of the present application. When setting up an underwater communication system, the underwater equipment is generally arranged directly on the cable and wound on the cable to be lowered into the water with the cable.

[0041] In the heat dissipation device, the water-permeable component 200 has a conical structure. The water-permeable component 200 is arranged at each of two ends of the heat dissipation shell 100, such that the water-permeable component 200 is connected to the outer wall shell body 110, and the water-permeable component 200, the outer wall shell body 110, and the underwater equipment shell together form a heat dissipation chamber 120. For illustration, two water-permeable components 200 are provided in the heat dissipation device, and the two water-permeable components 200 are arranged at two ends of the heat dissipation shell 100.

[0042] In some embodiments of the present application, both ends of the outer wall shell body 110 may be provided with internal threads, the water-permeable component 200 is provided with external threads, and the outer wall shell body 110 and the water-permeable component 200 may be connected by these threads to form the heat dissipation chamber 120. It should be noted that the above-mentioned connection mode is only one possible connection mode between the outer wall shell body 110 and the water-permeable component 200, and the connection mode between the outer wall shell body 110 and the water-permeable component 200 is not limited within the scope of the present application.

[0043] In addition, in order to realize the heat dissipation of the water, as shown in [Fig. 3], a plurality of first water inlet holes 201 are arranged in an array on the water permeable component 200, so that when the underwater equipment enters the water with the cables, the water permeable component 200 located at each of the two ends of the heat dissipation shell 100 allows water to enter under the action of hydraulic pressure through the first water inlet holes 201, so that the heat dissipation chamber 120 is gradually filled with water and heat can be dissipated from the underwater equipment through the dissipation device and the water contained in the dissipation device after the underwater equipment has been buried in the underwater sediment.

[0044] In some embodiments, the diameter of the first water inlet hole 201 is less than 5 mm and greater than 1 mm. In this way, the situation in which a large amount of sediment enters the heat dissipation chamber 120 during the burial of the underwater equipment can be reduced and the heat dissipation efficiency of the underwater equipment can be increased. In addition, it can prevent the diameter of the first water inlet hole 201 from being too small, so that water can enter the heat dissipation chamber 120 through the first water inlet hole 201 during construction, thereby reducing the risk that the liquid in the heat dissipation chamber 120 is insufficient to ensure the heat dissipation efficiency.

[0045] For illustration purposes, a sieve having a pore size smaller than the diameter of the first water inlet hole 201 may be disposed in the water permeable component 200, in order to prevent small-sized sediment particles from penetrating and thus reduce the influence of sediment on the heat dissipation efficiency.

[0046] It should be noted that the diameter of the first water inlet hole 201 may be larger or smaller. The value indicated in the present application is only one possible implementation form, the specific diameter of the first water inlet hole 201 is not limited within the scope of the present application, but in order to ensure that large-sized sediment particles are prevented from entering and that water is ensured from entering, the diameter of the first water inlet hole 201 should be in the order of millimeters.

[0047] In some embodiments of the present application, as shown in [Fig. 4], the shell of the water-permeable component 200 may have a certain thickness and a groove may be provided in the first water inlet hole 201, so that the sediment contained in the water is retained to a certain extent and the risk of the sediment entering the heat dissipation chamber 120 is reduced. It will be understood that the water-permeable component 200 can rotate at a certain angle during installation and use, therefore, each first water inlet hole 201 is provided with a groove in each of the opposite up and down directions, which enables each first water inlet hole 201 to have a certain sediment filtering capacity.

[0048] It should be noted that the arrangement of the groove in the first water inlet hole 201 to reduce sediment penetration is only one possible implementation form, and in the specific implementation process, the shape of the hole channel of the first water inlet hole 201 may also be limited to reduce sediment, for example, the shape of the hole channel of the first water inlet hole 201 is set as a V-shaped or S-shaped path to reduce sediment penetration. In the present application, the shape of the hole channel of the first water inlet hole 201 is not limited.

[0049] For underwater equipment that is not equipped with the heat dissipation device, the heat dissipation effect of the underwater equipment may be Q1 = KlxSl, where Q1 is the amount of heat dispersed before the arrangement of the shell, Kl is the heat dissipation coefficient before the arrangement of the shell, and SI is the heat dissipation area before the arrangement of the shell. For underwater equipment equipped with the heat dissipation device, the heat dissipation effect of the underwater equipment may be Q2 = K2xS2, where Q2 is the amount of heat dispersed after the arrangement of the shell, K2 is the heat dissipation coefficient after the arrangement of the shell, and S2 is the heat dissipation area after the arrangement of the shell.

[0050] Due to the fact that the heat dissipation coefficient of the water is greater than the heat dissipation coefficients of the underwater equipment itself and the sediment, and the heat dissipation area of ​​the underwater equipment is increased to become the heat dissipation area of ​​the heat dissipation device as surrounded by the heat dissipation device arranged around it, the amount of heat dispersed after the arrangement of the heat dissipation device is greater than the amount of heat dispersed before the arrangement of the heat dissipation device at the same amount of heat supplied by the underwater equipment, the heat dissipation area of ​​the underwater equipment is increased, the conduction efficiency is increased, the dissipation efficiency thermal performance of underwater equipment in operation is increased, and the operating stability of the underwater communication system is improved.

[0051] In some embodiments of the present application, the outer wall shell body 110 and the water permeable component 200 are made of metal, because the metal has good thermal conductivity and can help the water contained in the heat dissipation chamber 120 to dissipate heat and improve the heat dissipation efficiency.

[0052] For illustration purposes, the outer wall shell body 110 and the water permeable component 200 are made of metal such as copper, aluminum, or iron. The outer wall shell 110 and the water permeable components 200 made of metal can increase the structural strength of the heat dissipation device for underwater equipment, and at the same time, the metal has high thermal conductivity to increase the heat dissipation efficiency of the underwater equipment.

[0053] It will be understood that, the underwater equipment located in the shallow areas must be buried under the water bottom, before laying the cable and the underwater equipment in the water, the heat dissipation device must be sheathed on the underwater equipment and wound with the cable on equipment of the construction ship, such as a cable guide rail and a hub. Therefore, the diameter of the outer wall shell body 110 in the heat dissipation shell 100 must meet the constraints of the cable guide rail and the hub to prevent the underwater equipment equipped with the heat dissipation device from being disengaged from the cable guide rail and the hub when wound on the cable guide rail and the hub, or the cable connected thereto from being damaged.

[0054] During the construction by the underwater communication system, the underwater equipment must be constructed with the cable. Therefore, the heat dissipation device arranged around the outside of the underwater equipment must be laid in the water and buried at the bottom of the water with the underwater equipment. During the construction, the underwater cables and equipment are wound on the cable guide rail and the hub, so as to lay the underwater cables and equipment in the water with the rotation of the hub. In addition, when the underwater communication system is laid in a shallow area, the underwater cables and equipment must be buried in the sediment at the bottom of the water, and the burial depth must be at least 3 m.The heat dissipation device must therefore have a certain structural strength, so as to prevent the structure of the heat dissipation device from being damaged when the winding and burial depths are large, and to reduce problems such as deformation of the outer wall shell body 110 and reduction of the . heat dissipation chamber 120.

[0055] In some embodiments, a fixing bracket 130 is also disposed in the heat dissipation shell 100. More specifically, the fixing bracket 130 is disposed between the underwater equipment shell and the outer wall shell body 110, and the fixing bracket 130 can provide support to the heat dissipation chamber 120 and improve the structural strength of the heat dissipation shell 100, thereby reducing the deformation of the heat dissipation shell 100 during construction, improving the reliability of the device, and avoiding the problem of reducing the heat dissipation efficiency due to the structural deformation.

[0056] In order to provide support to the heat dissipation shell 100, as shown in [Fig.5], the fixing bracket 130 may comprise at least one annular sheet 131. It will be understood that the annular sheet 131 has an annular sheet structure having a certain thickness, therefore the annular sheet 131 comprises two coaxial cylindrical arc faces, namely an inner annular surface and an outer annular surface, and the cross-sectional diameter of the inner annular surface is smaller than the cross-sectional diameter of the outer annular surface.

[0057] The cross-sectional diameter of the inner annular surface is equal to the cross-sectional diameter of the hull of the underwater equipment, and the cross-sectional diameter of the outer annular surface of the annular is equal to the cross-sectional diameter of the outer wall shell body 110. For illustration, the annular sheet 131 is to be arranged coaxially with the underwater equipment and the outer wall shell body 110, such that the inner annular surface bears against the hull of the underwater equipment and the outer annular surface bears against the outer wall shell body 110.

[0058] In this way, the arrangement of the annular sheet between the underwater equipment and the outer wall shell body 110 can support the heat dissipation chamber 120 formed by the heat dissipation shell 100 and the water-permeable component 200, and when the outer wall shell body 110 is compressed under the action of an external force, the external force can be partially transmitted to the underwater equipment by the annular sheet 131, thereby reducing the risk of structural deformation of the entire heat dissipation device.

[0059] In one embodiment of the present application, as shown in [Fig. 5], only one annular sheet 131 may be provided. In particular, the annular sheet 131 may be arranged in the central position of the heat dissipation chamber 120, i.e., the spaces on either side of the annular sheet 131 are identical, so that the support of the outer wall shell body 110 is uniform, thus improving the structural strength of the heat dissipation device.

[0060] For illustration purposes, as shown in [Fig.6], the fixing bracket 130 comprises three annular sheets 131, and the three annular sheets 131 are arranged in an array between the underwater equipment and the outer wall hull body 110. In particular, the first annular sheet 131a is arranged in the central position of the heat dissipation chamber 120, the second annular sheet 131b and the third annular sheet 131c are respectively arranged on either side of the first annular sheet 131a, and the second annular sheet 131b and the third annular sheet 131c are arranged at the same distance from the first annular sheet 131a.The arrangement of the plurality of annular sheets 131 makes it possible to increase the support strength of the outer wall shell body 110, to accordingly increase the structural strength of the heat dissipation device and to reduce the risk of structural deformation of the heat dissipation device under pressure.

[0061] It will be understood that the annular sheets 131 may be one or more in number, the number of the annular sheets 131 is not limited within the scope of the present application, and the mode of arranging one or the three annular sheets 131 mentioned above is only one example in the present application, and the number of the annular sheets 131 is not limited to these examples.

[0062] In addition, in order to facilitate the installation of the heat dissipation shell 100 on the underwater equipment, the outer wall shell body 110 may have a two-semi-cylinder structure, and the two are connected to each other by a hinge, thereby controlling the opening and closing of the outer wall shell body 110 by the hinge during use, so that the underwater equipment can be placed in the outer wall shell body 110. It will be understood that, in order to facilitate the installation, when the outer wall shell body 110 has a two-semi-cylinder structure, the annular sheet 131 may have a semi-annular structure, so that the annular sheet 131 can be opened and closed with the opening and closing of the outer wall shell body 110, thereby reducing the difficulty of installing the underwater equipment on the outer wall shell body. 110.

[0063] As shown in [Fig.6], when the fixing bracket 130 comprises a plurality of annular sheets 131, the annular sheets 131 prevent water from flowing into the heat dissipation chamber 120. In some embodiments, a plurality of water-permeable holes 1311 are arranged in an array on the annular sheets 131, and the diameter of the water-permeable holes 1311 is less than or equal to the diameter of the first water inlet hole 201. In this way, once the heat dissipation chamber 120 is divided into several chamber segments by the plurality of annular sheets 131, the liquid flow can be realized through the water permeable holes 1311, thereby increasing the heat dissipation efficiency of the underwater equipment by using the heat dissipation device for underwater equipment.

[0064] In some embodiments of the present application, to improve the stability of the installation of the heat dissipation device, as shown in [Fig. 6], the annular sheet 131 may be provided with a friction member 1312. For illustration, the friction member 1312 is disposed between the inner annular surface and the hull of the underwater equipment, and the friction member 1312 serves to increase the frictional force between the annular sheet 131 and the underwater equipment, thereby reducing the sliding of the heat dissipation hull 100 relative to the underwater equipment and improving the structural stability of the heat dissipation hull 100 and the underwater equipment.

[0065] In addition, in order to increase the supporting strength of the annular sheet 131 for the heat dissipation shell 100, as shown in [Fig. 6], the outer wall shell body 110 is provided with a fixing groove 140, the annular sheet 131 is disposed in the fixing groove 140, and the fixing groove 140 fits without clearance with the annular sheet 131, so that the fixing groove 140 clamps the annular sheet 131 to dispose the annular sheet 131 between the shell of the underwater equipment and the outer wall shell body 110. In this way, the outer wall shell body 110 serves to fix the annular sheet 131, which increases the supporting strength of the annular sheet 131 for the heat dissipation chamber 120, thereby improving the structural strength of the heat dissipation device for underwater equipment.

[0066] In some embodiments, the annular sheet 131 is also disposed on the outer wall shell body 110 by welding, nesting, bonding, or the like, and the specific disposition mode of the annular sheet 131 is not limited within the scope of the present application.

[0067] In some embodiments of the present application, to increase the filling speed of water in the heat dissipation chamber 100 and avoid insufficient filling of water in the heat dissipation chamber 120 during burial, as shown in [Fig. 7], a plurality of second water permeable holes 111 may be arranged in an array on the heat dissipation shell 100, and the diameter of the second water permeable holes 111 is less than or equal to the diameter of the first water inlet holes 201.

[0068] For illustrative purposes, to reduce sediment penetration, the second water-permeable holes 111 may be arranged on two opposite sides of the body of outer wall shell 110, and when burying the heat dissipation shell 100, it is desirable to orient the second water-permeable holes 111 toward both sides of the underwater equipment, so as to prevent sediment from entering the heat dissipation shell due to extrusion applied by the soil in the upward or downward directions after burial.

[0069] The arrangement of the second water-permeable holes 111 on the heat dissipation shell 100 makes it possible to increase the filling speed of water in the heat dissipation chamber 120, thereby avoiding the problem of insufficient filling of water in the heat dissipation chamber 120.

[0070] In some embodiments of the present application, as shown in [Fig. 8], the fixing bracket 130 comprises a plurality of support columns 132, and the support columns 132 are arranged in an array to form one or more annular structures that provide support to the outer wall shell body 110. For example, the plurality of support columns 132 may form a partition bar-shaped annular structure that provides support to the outer wall shell body 110. The two adjacent support columns 132 are provided with pores that allow water to flow between the pores. In this way, the arrangement of the plurality of support columns 132 can provide a support function, thereby reducing the risk of structural deformation.

[0071] For illustration purposes, the support columns 132 may also be provided with the water-permeable holes 1321, so that water can flow through the water-permeable holes 1321. In some embodiments, when the fixing bracket 130 comprises a plurality of support columns 132, the outer wall shell body 110 may be provided with fixing grooves 140 shaped to correspond to one end of the support column 132 to cooperate with this end and allow the support columns 132 to be arranged between the underwater equipment and the outer wall shell body 110.

[0072] It will be understood that the support columns 132 are arranged on the outer wall shell body 110 by welding, nesting, gluing or the like, the specific arrangement mode of the support column 132 not being limited within the scope of the present application.

[0073] To increase structural strength, the mounting bracket 130 may also be made of metal and in some embodiments of the present application, the material of the mounting bracket 130 may be the same as that of the outer wall shell body 110 and the water permeable component 200.
