Description

Technical Field

[0001] This utility model relates to the field of power accessories, and in particular to a water-cooled power cable. Background Technology

[0002] Currently, to address the issue of excessive heat in some power cables affecting their performance, water-cooled power cables have emerged, using water cooling to lower the cable temperature. Most existing water-cooled power cables consist of an insulated water pipe embedded within the cable, with the cable core resting against the outer wall of the pipe. Cooling water flows through this pipe, with both ends placed in a cooling water tank. A water pump is connected in series with the pipe to continuously supply cold water. When the cable core is energized and heats up, the heat is first transferred to the outer wall of the water pipe where it contacts the cable core, and then to the cold water inside the pipe. However, because both the water pipe and the cable core are cylindrical, the contact area between them is limited. This results in limited heat transfer between the cable core and the water pipe, and the water pipe can only absorb heat from one side of the cable core. This makes it difficult to achieve a comprehensive and effective cooling effect, leading to slow cooling speed and limited improvement in the performance of the power cable. Therefore, it is essential to design a water-cooled power cable to solve the aforementioned technical problems. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned problems and shortcomings, and to provide a water-cooled power cable. This water-cooled power cable can more comprehensively and effectively absorb the heat on the conductor, and can play a very comprehensive and effective cooling role, thereby improving the cooling speed and the performance of the power cable. It has very high reliability and applicability.

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

[0005] A water-cooled power cable includes a conductor, an insulating water pipe, and an insulating outer tube. The cable is characterized in that a C-shaped retaining strip extending axially is integrally formed on the outer wall of the insulating water pipe. The C-shaped retaining strip is fitted onto the conductor, and both the conductor and the insulating water pipe are arranged in the insulating outer tube.

[0006] Preferably, there are two wire cores, and C-shaped clips are formed integrally with the outer walls of both sides of the insulating water pipe, with the two C-shaped clips respectively clamped onto the two wire cores.

[0007] Preferably, the outer wall of the insulating water pipe is provided with a C-shaped metal strip extending along its axial direction, and the C-shaped clip covers the C-shaped metal strip.

[0008] Preferably, a plurality of heat dissipation fins are integrally formed on the outer arc surface of the C-shaped metal strip and inserted into the inner hole of the insulating water pipe.

[0009] Preferably, the heat sink is a heat sink strip extending along the length of the C-shaped metal strip.

[0010] Preferably, the C-shaped metal strip and each heat sink are integrated into a profile structure.

[0011] The beneficial effects of this utility model are as follows: In this water-cooled power cable, the insulating water pipe allows for the flow of cooling water; by integrally forming a C-shaped retaining strip extending axially on the outer wall of the insulating water pipe and securing it to the wire core, not only can the insulating water pipe and the wire core be accurately and stably positioned together, but the C-shaped retaining strip also greatly increases the contact area. This allows the heat generated by the wire core to be comprehensively and quickly conducted to the insulating water pipe, resulting in a very comprehensive and effective cooling effect on the wire core, thereby improving the cooling speed and enhancing the performance of the power cable. Therefore, this water-cooled power cable possesses very high reliability and applicability. Attached Figure Description

[0014] Figure 3 This is a schematic diagram of the C-shaped metal strip in this utility model. Detailed Implementation

[0015] like Figure 1 As shown, the water-cooled power cable of this utility model includes a conductor 1, an insulating water pipe 2, and an insulating outer tube 3. To achieve the purpose of this utility model, a C-shaped retaining strip 21 extending axially is integrally formed on the outer wall of the insulating water pipe 2. The C-shaped retaining strip 21 is a long strip with a C-shaped radial cross section. The C-shaped retaining strip 21 is fitted onto the conductor 1. Both the conductor 1 and the insulating water pipe 2 are arranged in the insulating outer tube 3.

[0016] In this water-cooled power cable, the insulated water pipe 2 allows for the flow of cooling water. A C-shaped retaining strip 21, extending axially and integrally formed on the outer wall of the insulated water pipe 2, is then attached to the conductor 1. This not only accurately and stably positions the insulated water pipe 2 and the conductor 1 together, but also significantly increases the contact area through the C-shaped retaining strip 21. This allows for the comprehensive and rapid transfer of heat generated by the conductor 1 to the insulated water pipe 2, resulting in a highly effective cooling effect on the conductor 1. This, in turn, improves the cooling speed and enhances the performance of the power cable. Therefore, this water-cooled power cable exhibits high reliability and applicability.

[0017] like Figure 1 and Figure 2 As shown, there are two conductor cores 1. C-shaped retaining strips 21 are integrally formed on the outer walls of both sides of the insulating water pipe 2, and the two C-shaped retaining strips 21 are respectively secured to the two conductor cores 1. This not only accurately and stably positions the two conductor cores 1, but also effectively prevents them from contacting each other, and simultaneously cools both conductor cores 1, thereby helping to further improve the reliability and applicability of this water-cooled power cable structure.

[0018] like Figure 1 and Figure 2 As shown, a C-shaped metal strip 22 extending axially is provided on the outer wall of the insulating water pipe 2. The C-shaped metal strip 22 is a metal strip with a C-shaped radial cross-section, and the C-shaped clamping strip 21 covers the C-shaped metal strip 22. The C-shaped metal strip 22 enhances the structural strength of the C-shaped clamping strip 21, which helps to improve the stability and reliability of the C-shaped clamping strip 21 in clamping the wire core 1. The C-shaped metal strip 22 also has a very good heat absorption effect, so that the heat of the wire core 1 can be carried away more quickly. This helps to further improve the reliability and applicability of the water-cooled power cable structure.

[0019] like Figures 1 to 3 As shown, a plurality of heat dissipation fins 23 are integrally formed on the outer arc surface of the C-shaped metal strip 22, which pass through the inner holes 24 of the insulating water pipe 2. This allows the heat generated by the wire core 1 to be transferred to the cold water in the insulating water pipe 2 more quickly through the C-shaped metal strip 22 and each heat dissipation fin 23, thereby further improving the heat dissipation speed and thus helping to further improve the reliability and applicability of the water-cooled power cable.

[0020] like Figure 1As shown, the C-shaped metal strip 22 and each heat sink 23 are made of elastic steel strips, which not only provide reliable structural reinforcement but also offer excellent thermal conductivity and meet the normal bending requirements of the power cable. The insulating water pipe 2 uses the elastic insulating plastic found in existing power cables, which not only provides excellent insulation but also meets the normal bending requirements of the power cable. The space between the insulating outer tube 3 and the insulating water pipe 2, and between the insulating outer tube 3 and the conductor 1, is filled with insulating reinforcing filler 10. The reinforcing filler 10 uses the reinforcing filler found in existing cables, which not only enhances insulation but also accurately and stably positions the conductor 1 and the insulating water pipe 2, thereby helping to further improve the reliability and applicability of this water-cooled power cable structure.

[0021] The insulating water pipe 2 has sealing plugs (not shown in the figure) that match the ports at both ends. Each of the two sealing plugs has a connecting interface that communicates with the insulating water pipe 2. Water pipes are connected to the two connecting interfaces, and the outer ends of the two water pipes are placed in the cooling water tank. A water pump is connected in series to one of the water pipes, so that cold water can be circulated into the insulating water pipe 2 through the water pump, thereby providing continuous water cooling for the power cable, which can meet the needs of actual manufacturing and use.

[0022] like Figure 2 and Figure 3 As shown, the heat sink 23 is a heat sink strip extending along the length of the C-shaped metal strip 22. This provides better thermal conductivity, thereby further improving cooling performance.

[0023] like Figure 2 and Figure 3 As shown, the C-shaped metal strip 22 and each heat sink 23 are integrated into a profile structure. This not only provides a stable and reliable structure but also greatly improves the convenience of mass production, thereby helping to further enhance the reliability and applicability of the water-cooled power cable.
