Description

Technical Field

[0001] This utility model relates to the field of data cables, and in particular to a cable for data centers. Background Technology

[0002] Data cables are a type of cable used in the field of communication transmission, mainly for signal transmission in scenarios such as building integrated wiring, community computer networks, and broadband access networks.

[0003] Existing data cables generally generate relatively little heat. However, with the development of high-speed transmission, the heat dissipation requirements for data cables have also increased. For example, Chinese patent 202421122060.6 adopts a ventilation design to meet the heat dissipation requirements. However, in actual cable extrusion molding, this structure is difficult to mass-produce.

[0004] Therefore, the key to the design is how to achieve heat dissipation for data cables while also ensuring stable production. Utility Model Content

[0005] The main purpose of this invention is to propose a data center cable that improves existing data cables, enabling active heat dissipation while achieving stable production.

[0006] To achieve the above objectives, this utility model proposes a data center cable, comprising: The inner core has multiple wires, and the outer wall of the inner core is recessed with an arc-shaped heat dissipation groove that extends along the length of the wires. A diaphragm, the diaphragm covering the wall of an inner core, the diaphragm having a predetermined hardness. The heat dissipation grooves and the diaphragm form a heat dissipation channel; An adhesive layer is applied to the outer wall of the diaphragm; A sheath, which covers the outer wall of the diaphragm, wherein the melting point of the diaphragm is greater than that of the sheath.

[0007] In actual production, the wire core is covered by an inner insulation layer, and heat dissipation grooves are formed on the outer wall of the inner core. In actual molding, laser molding, spiral molding during injection molding, or etching molding can be used. Then, a one-piece molded diaphragm is used to cover the outer wall of the inner core. In actual production, the inner wall of the diaphragm is larger than the outer wall of the inner core by a predetermined size, forming a predetermined gap. It is then fitted onto the outer wall of the inner core. This can also be understood as an integral extrusion molding process followed by cooling and then attachment, thus forming a heat dissipation channel. Because of the difference in melting points between the sheath and the diaphragm, gaps can easily form. Therefore, by applying adhesive before extruding the sheath layer, it is possible to prevent the sheath from melting and disrupting the heat dissipation channels, and also to improve the fit between the diaphragm and the sheath. Meanwhile, the extrusion molding of the sheath can tighten the diaphragm layer, thereby improving the fit of each layer of the data cable and enhancing structural stability.

[0008] After the cable is formed, a ventilation test is required. Under a predetermined pressure, the heat dissipation channel must be kept clear. At the same time, when the pressure is higher than the predetermined pressure, there should be no delamination. This is to ensure that the cable passes the test.

[0009] Although the design structure is simple, ensuring production stability during molding is one of the key aspects of the design.

[0010] Specifically, the materials for the diaphragm and sheath can utilize existing structures, with the main design feature being the ability to achieve extrusion molding and prevent deformation at the melting temperature. Attached Figure Description

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0016] like Figures 1 to 4 As shown, a data center cable includes: The inner core 1 is provided with a plurality of wire cores 10. The outer wall of the inner core 1 is recessed with an arc-shaped heat dissipation groove that extends along the length of the wire cores 10. A diaphragm 3, which covers the wall of the inner core 1, has a predetermined hardness. The heat dissipation groove and the diaphragm 3 form a heat dissipation channel 2; Adhesive layer 30, the adhesive layer 30 being coated on the outer wall of the diaphragm 3; Sheath 31, which covers the outer wall of diaphragm 3, wherein the melting point of diaphragm 3 is greater than the melting point of sheath 31.

[0017] In actual production, the wire core 10 is covered by the insulation layer of the inner core 1, and heat dissipation grooves are formed on the outer wall of the inner core 1. In actual molding, laser molding, spiral molding during injection molding, or etching molding can be used. Then, the integrally formed diaphragm 3 is wrapped around the outer wall of the inner core 1. In actual production, the inner wall of the diaphragm 3 is larger than the predetermined size of the outer wall of the inner core 1, forming a predetermined gap, and is then fitted onto the outer wall of the inner core 1. This can also be understood as an integral extrusion molding process followed by cooling and then attachment, thus forming the heat dissipation channel 2. Because there is a melting point difference between the sheath 31 and the diaphragm 3, gaps can easily occur. Therefore, by applying adhesive and then extruding the sheath 31 layer, it is possible to avoid the sheath 31 melting and causing interruption of the heat dissipation channel 2, and also to improve the adhesion between the diaphragm 3 and the sheath 31. Meanwhile, after extrusion molding, the sheath 31 can tighten the three layers of the diaphragm, thereby improving the fit of each layer of the data cable and enhancing structural stability.

[0018] After the cable is formed, a ventilation test is required. Under a predetermined pressure, the heat dissipation channel 2 must be kept unobstructed. At the same time, when the pressure is higher than the predetermined pressure, there should be no delamination. This is to ensure that the cable passes the test.

[0019] Although the design structure is simple, ensuring production stability during molding is one of the key aspects of the design.

[0020] Specifically, the materials of the diaphragm 3 and the sheath 31 can adopt existing structures, and their main design is to enable extrusion molding and prevent deformation at the melting temperature.

[0021] Specifically, when the inner core 1 is flat, the heat dissipation channels 2 are distributed in a wavy line shape; When the inner core 1 is cylindrical, the heat dissipation channels 2 are distributed in a spiral shape.

[0022] Existing cables are generally flat or cylindrical, so the shape of heat dissipation channel 2 is also different.

[0023] In this embodiment of the utility model, the heat dissipation channel 2 is provided with at least two channels, and the two heat dissipation channels 2 are arranged in parallel.

[0024] Specifically, the heat dissipation channel 2 is etched or laser-cut, and the heat dissipation channel 2 is preferably a microchannel, such as 1mm, 2mm, 0.5mm, which does not affect the structural stability and at the same time improves the thermal conductivity of the inner core 1.

[0025] In this embodiment of the invention, the heat dissipation channel 2 is embedded with a cooling microtube.

[0026] Specifically, the cooling microtubes are stainless steel spiral tubes (Ф1.5mm) with ethylene glycol water-soluble waves flowing through them (flow rate 0.5L / min), thereby enhancing heat exchange.

[0027] In practical designs, cooling microtubes can be wound into an embedded structure; however, this structure is mainly used in data centers where large bending angles are not required. Therefore, heat exchange efficiency can be improved.

[0028] Specifically, the cooling microtube is a stainless steel spiral tube with a diameter of 1.5 mm.

[0029] In this embodiment of the invention, the carrier of the heat dissipation channel 2 is gas.

[0030] Specifically, air pumps are connected to both ends of the heat dissipation channel 2, with one end being a fluid inlet and the other end being a fluid outlet.

[0031] When two heat dissipation channels 2 are arranged side by side, the air pump is located at the same end of the heat dissipation channel 2. In actual design, it is difficult to ensure airtightness. It is preferable to adopt a structure with only one heat dissipation channel 2, thereby reducing production difficulty and production cost.

[0032] Specifically, the inner core 1 is made of silicone rubber, which has both support and a predetermined degree of deformation.

[0033] In addition to cooling, the additional cooling microtubes can also form a shielding layer. Their curvature is significantly limited by the material, for example, the bending radius is greater than 1 meter. The above description is merely a preferred embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model, utilizing the content of this specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
