Description

Technical Field

[0001] This utility model relates to the field of power accessories, and in particular to a power cable made of MPP modified material. Background Technology

[0002] Because MPP-modified power cables possess high heat resistance, they are frequently used in applications with high heat generation. While this meets certain usage requirements, the limited heat dissipation of most existing MPP-modified power cables, which use MPP-modified insulation to wrap the conductor, makes them prone to excessive heat generation during use. This not only affects cable performance but also accelerates the aging of the MPP-modified material, leading to reduced lifespan, increased maintenance costs, increased safety hazards, and unsuitability for applications with high heat generation. Therefore, a redesign of the structure of MPP-modified power cables is essential. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned problems and shortcomings, and to provide an MPP modified material power cable. This MPP modified material power cable can generate a comprehensive and effective cooling effect to avoid excessive heat during operation. This not only helps to reduce the impact on performance, but also slows down the aging rate, thereby achieving advantages such as extended service life, reduced maintenance costs, reduced safety hazards, and applicability in scenarios with high heat generation.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A modified MPP power cable includes a conductor and an insulating sheath wrapped around the conductor. It is characterized by further including metal heat-absorbing strips and heat-dissipating strips. The insulating sheath has spiral holes for coolant flow, and these spiral holes are arranged around the conductor. The heat-absorbing strips are embedded in the insulating sheath and arranged spirally around the conductor, with the heat-absorbing strips located inside the spiral holes. The heat-dissipating strips are embedded in the insulating sheath and arranged spirally around the conductor. The heat-dissipating strips are connected to the heat-absorbing strips and pass through the spiral holes.

[0006] Preferably, both the heat-absorbing strips and the heat-dissipating strips are made of elastic stainless steel sheet structure.

[0007] Preferably, the heat-absorbing strip and the heat-dissipating strip are integrally formed.

[0008] Preferably, the heat dissipation fins are arranged perpendicular to the outer wall of the heat absorption fins.

[0009] Preferably, the heat dissipation fins are connected to the middle of the outer wall of the heat absorption fins.

[0010] Preferably, the sidewall of the heat dissipation fin is connected to the outer wall of the heat absorption fin with a rounded transition.

[0011] Preferably, the surface of the heat sink strip is provided with a plurality of heat dissipation protrusions, and each heat dissipation protrusion is located in a spiral hole.

[0012] The beneficial effects of this invention are as follows: The MPP modified power cable utilizes metal heat-absorbing and heat-dissipating strips, and spiral holes for coolant flow are formed in the insulation. These spiral holes, heat-absorbing strips, and heat-dissipating strips are all arranged around the conductor. This allows the heat-absorbing strips to comprehensively and effectively absorb the heat generated by the conductor, while the heat-dissipating strips quickly transfer the absorbed heat to the spiral holes, where the coolant rapidly dissipates the heat. Therefore, the MPP modified power cable achieves rapid and effective cooling, preventing excessive heat during operation. This not only reduces the impact on performance but also slows down aging, resulting in extended service life, reduced maintenance costs, lower safety hazards, and suitability for applications with high heat generation. Furthermore, the heat-absorbing and heat-dissipating strips effectively enhance the cable's structural strength without affecting its normal bending, thereby improving the reliability of the MPP modified power cable.

[0017] like Figures 1 to 3As shown, the MPP modified material power cable of this utility model includes a conductor 1 and an insulating sheath 2 wrapped around the conductor 1. To achieve the purpose of this utility model, it also includes heat-absorbing strips 3 and heat-dissipating strips 4 made of metal. The insulating sheath 2 has a spiral hole 21 for coolant to flow through, and the spiral hole 21 is arranged around the conductor 1. The heat-absorbing strip 3 is embedded in the insulating sheath 2 and is arranged spirally around the conductor 1. The heat-absorbing strip 3 is located inside the spiral hole 21. The heat-dissipating strip 4 is embedded in the insulating sheath 2 and is arranged spirally around the conductor 1. The heat-dissipating strip 4 is connected to the heat-absorbing strip 3 and is inserted through the spiral hole 21.

[0018] This MPP modified power cable employs metal heat-absorbing strips 3 and heat-dissipating strips 4, with spiral holes 21 for coolant flow in the insulation 2. All three elements—spiral holes 21, heat-absorbing strips 3, and heat-dissipating strips 4—are arranged around the conductor 1. This allows the heat-absorbing strips 3 to effectively absorb the heat generated by the conductor 1, while the heat-dissipating strips 4 quickly transfer the absorbed heat to the spiral holes 21, where the coolant rapidly dissipates the heat. Therefore, this MPP modified power cable achieves rapid and effective cooling, preventing excessive heat during operation. This not only reduces the impact on performance but also slows down aging, resulting in advantages such as extended service life, reduced maintenance costs, lower safety hazards, and suitability for applications with high heat generation.

[0019] Meanwhile, the heat-absorbing strips 3 and heat-dissipating strips 4 can effectively enhance the structural strength of the cable without affecting its normal bending, thereby improving the reliability of the MPP modified power cable.

[0020] The insulation sheath 2 is made of MPP modified material. The heat-absorbing strips 3 and heat-dissipating strips 4 do not directly contact the wire core 1. They are separated from the wire core 1 by the insulation sheath 2. This ensures that the MPP modified material power cable has very good performance.

[0021] In the actual manufacturing process, connecting pipes are sealed and installed in the two openings of the spiral hole 21, and the two connecting pipes are connected to the cooling water tank by two liquid guide pipes. A water pump is connected in series on one of the liquid guide pipes, so that cold water can be circulated into the spiral hole 21, thereby achieving a continuous cooling effect and meeting the needs of actual use.

[0022] Both the heat-absorbing strip 3 and the heat-dissipating strip 4 are made of elastic stainless steel. This not only provides excellent heat absorption and dissipation but also offers reliable reinforcement, thereby further improving the reliability and applicability of the MPP modified power cable.

[0023] like Figures 1 to 4 As shown, the heat-absorbing strip 3 and the heat-dissipating strip 4 are integrally formed. This not only facilitates mass production but also provides better heat transfer and more reliable reinforcement, thereby further improving the reliability and applicability of the MPP modified material power cable.

[0024] like Figure 2 and Figure 4 As shown, the heat dissipation fins 4 are arranged perpendicular to the outer wall of the heat absorption fins 3. This ensures a stable structure in the assembly of the heat dissipation fins 4 and the heat absorption fins 3, enabling them to work together to provide a very stable and reliable reinforcement effect.

[0025] like Figure 2 and Figure 4 As shown, the heat dissipation strip 4 is connected to the middle of the outer wall of the heat absorption strip 3. This ensures very uniform and stable heat conduction, thereby facilitating better heat dissipation and further improving the reliability and applicability of the MPP modified material power cable.

[0026] like Figure 2 and Figure 4 As shown, the sidewall of the heat dissipation strip 4 is connected to the outer wall of the heat absorption strip 3 by a rounded transition. This makes the assembly of the heat dissipation strip 4 and the heat absorption strip 3 more stable and reliable, thereby helping to further improve the reliability and applicability of the MPP modified material power cable.

[0027] like Figure 2 and Figure 4 As shown, the surface of the heat sink strip 4 is provided with a plurality of heat dissipation protrusions 41, and each heat dissipation protrusion 41 is located in the spiral hole 21. This can further improve the heat dissipation speed, thereby further improving the reliability and applicability of the MPP modified material power cable.
