Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a liquid-cooled charging flat cable for aircraft. Background Technology

[0002] Airports typically have dedicated charging stations on the ground. When an aircraft is parked, ground staff connect the charging cables from the charging stations to the aircraft, providing power from the ground. This method of power supply allows aircraft to operate without burning aviation fuel while parked, effectively saving energy and significantly reducing noise pollution.

[0003] Currently used charging cables generally adopt a circular cross-section design. Their internal structure includes conductive cores and an outer sheath. To ensure cable strength, some filler material is also added inside. At the same time, to ensure the cable's heat dissipation performance, cooling channels are specially set up inside the sheath for cooling the cable, making the overall cable structure relatively complex. In addition, the internal core of this type of cable is usually made of multiple strands of fine copper wires twisted together, resulting in a relatively thick core diameter. This leads to the existing cooling channel design being ineffective in cooling the thick core. When the cable needs to carry a large current to meet the requirements of fast charging, the heat generation of the cable becomes even more severe. Utility Model Content

[0004] The present invention aims to provide a liquid-cooled flat charging cable for aircraft to solve the problem of poor cooling effect of current charging cables.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A liquid-cooled charging flat cable for aircraft, comprising two sets of main conductors, each main conductor having a set of cores, the outer side of each core being covered with a semi-conductive shielding layer, the semi-conductive shielding layer being located inside the main conductors, a gap between the semi-conductive shielding layer and the main conductors forming a cooling cavity, the cooling cavity containing a cooling medium; both sets of main conductors are covered with conductor layers, and the outer side of each conductor layer is covered with an insulating layer.

[0006] The principle and advantages of this solution are as follows: Through the above structural design, the gap between the semi-conductive shielding layer and the main conductor acts as a cooling cavity filled with a cooling medium. This allows for simultaneous cooling of the inner conductor and the outer main conductor, achieving bidirectional cooling and improving the cable's overall cooling effect. Simultaneously, the semi-conductive shielding layer better prevents external electromagnetic interference, enhancing the cable's resistance to external interference and ensuring stable current transmission through the conductor. Furthermore, the semi-conductive shielding layer isolates the inner conductor from the outer main conductor, reducing the external temperature impact on the conductor and ensuring effective cooling. Overall, this results in superior cable cooling performance.

[0007] Furthermore, the arrangement of the wire cores in this scheme simplifies the grouping of stranded wire cores and the processing flow of the wire cores.

[0008] Preferably, as an improvement, it also includes a sheath, in which the two sets of main conductors and their corresponding conductor layers and insulation layers are located, and a grounding core is also provided inside the sheath.

[0009] The above solution integrates the various wire harnesses and media through the design of the sheath, ensuring the strength of the cable.

[0010] Preferably, as an improvement, the sheath has an elongated oval cross section, with two sets of main lines arranged side by side.

[0011] The above solution makes the overall cross-section of the cable flat and round. Compared with the conventional circular design, it saves materials while giving it a smaller bending radius, improving the cable's flexibility and bending ability.

[0012] Preferably, as an improvement, the grounding conductor is located within the angle between the two sets of main conductors.

[0013] The above method fills the gap between the two main conductors by filling the angle between the grounding conductors, thereby improving the strength of the cable.

[0014] Preferably, as an improvement, a filler material is used to fill the space between the sheath and the insulation layer.

[0015] The above method uses filling material to fill and support the space inside the cable, ensuring cable strength while preventing cable deformation.

[0016] Preferably, as an improvement, the cooling medium is a coolant, which fills the cooling chamber.

[0017] The above method utilizes coolant to cool the cable, ensuring a cooling effect.

[0018] Preferably, as an improvement, the semiconductive shielding layer is extruded outside the wire core.

[0019] The above solution makes the connection between the semiconductive shielding layer and the wire core more stable, which helps to ensure the strength and deformation resistance of the cable structure. Attached Figure Description

[0023] The following detailed description provides further details on specific embodiments, but the embodiments of this utility model are not limited thereto. Unless otherwise specified, the technical means used in the following embodiments are conventional means well known to those skilled in the art; the experimental methods used are all conventional methods; and the materials and reagents used are all commercially available.

[0024] A liquid-cooled charging flat cable for aircraft, such as Figure 1 and Figure 2 As shown, the system includes two sets of main conductors 1, each containing a set of conductor cores 2. Each conductor core 2 is covered by a semi-conductive shielding layer 3, which is extruded over the conductor core 2 and located within the main conductors 1. A gap exists between the semi-conductive shielding layer 3 and the main conductors 1, forming a cooling cavity 4. The cooling cavity 4 contains a cooling medium; in this embodiment, the cooling medium is a coolant, which fills the cooling cavity 4. Both sets of main conductors 1 are covered by conductor layers 5, and each conductor layer 5 is covered by an insulating layer 6.

[0025] It also includes a sheath 7, which has an elongated oval cross-section. The two sets of main conductors 1, the corresponding conductor layer 5, and the insulation layer 6 are all located inside the sheath 7, with the two sets of main conductors 1 arranged side by side. The space between the sheath 7 and the insulation layer 6 is filled with a filler material 8. A grounding core 9 is also provided inside the sheath 7, located within the angle between the two sets of main conductors 1.

[0026] In this embodiment, when the cable is in use, the gap between the semi-conductive shielding layer 3 and the main conductor 1 acts as a cooling cavity 4 and is filled with a cooling medium. This allows for simultaneous cooling of the inner core 2 and the outer main conductor 1, achieving bidirectional cooling and improving the cable's overall cooling effect. Simultaneously, the semi-conductive shielding layer 3 better prevents external electromagnetic interference, enhancing the cable's resistance to external interference and ensuring stable current transmission through the core 2. Furthermore, the semi-conductive shielding layer 3 isolates the inner core 2 from the outer main conductor 1, reducing the external temperature impact on the core 2 and ensuring effective cooling. Overall, this results in a superior cooling effect for the cable.

[0027] The design of the sheath 7 integrates all wire harnesses and dielectric materials, ensuring the strength of the cable. The overall cross-section of the cable is flat and round, which saves materials and gives it a smaller bending radius compared to the conventional round design, improving the cable's flexibility and bending ability.

[0028] The grounding core 9 fills the gap between the two main conductors 1 to improve the strength of the cable.

[0029] The filling material 8 fills and supports the space inside the cable, ensuring the cable's strength while preventing cable deformation.
