TECHNICAL FIELD
[0001] The utility model belongs to the heat dissipation type cable matching structure design technical field, especially relate to a fastening type sustainable heat dissipation cable. BACKGROUND
[0002] Cable is a common current flow channel unit, which is widely used in various technical fields. When the cable is applied to large current transmission work, a large amount of heat will be generated when the current passes through the cable. If this heat cannot be dissipated in time, not only the transmission efficiency of the cable and the service life of the cable sheath will be affected, but also the cable will be prone to self-ignition after long-term heat accumulation, which increases the safety hazard. Therefore, the cable needs to be cooled in time. Especially for some high-cost large equipment supporting cables, once the cable overheats and catches fire, it will bring huge economic losses and safety hazards to these equipment. At present, many cables are buried in the ground or buried in the wall, so there is no natural wind on the surface of the cable to carry heat, which makes the heat dissipation more worrying. SUMMARY
[0003] To solve the above technical problems, the utility model provides a fastening type sustainable heat dissipation cable, which comprises a strip-shaped lower shell, the lower shell comprises a semicircular open pipeline with an axial front-back horizontal and a radial open semicircular shape (the semicircular angle is 180°), the semicircular opening of the semicircular open pipeline is vertically upward, and the length direction of the cable body is consistent with the semicircular open pipeline.
[0004] On the top edge (i.e. the two side edges of the semicircular opening) of the semicircular open pipeline on the left and right sides, a convex plate with a length direction parallel to the semicircular open pipeline is vertically upward and symmetrically extended, and the convex plate is formed by bending the left and right plate surfaces vertically outward as a whole in the radial direction.
[0005] A upper shell is arranged above the lower shell, the upper shell comprises a strip-shaped plate with a length direction horizontally front-back, the upper and lower plate surfaces of the strip-shaped plate are horizontally arranged, and the lower plate surface of the strip-shaped plate is fixedly connected with an arc-shaped matching groove parallel to the strip-shaped plate in the axial direction, the groove opening of the arc-shaped matching groove (the arc angle is 120°) is vertically downward, and the cable body is vertically upward and parallel to the arc-shaped matching groove.
[0006] On the left and right sides of the strip plate, symmetrical vertical connecting plates extend downwards, parallel to the length of the strip plate. The left and right sides of the connecting plates are vertically set. The connecting plates are bent outwards horizontally in a local section in the radial direction to form a groove with the length direction consistent with the connecting plate and the groove opening facing inwards. The convex plate fills and presses into the groove on the corresponding side through its own convex structure, thereby realizing the fit and cover between the upper shell and the lower shell. The cable body is clamped by the arc fitting groove and the semi-circular open pipe. At the same time, the arc fitting groove abuts against the convex plates on the left and right sides respectively.
[0007] A cooling water pipe is fixedly connected to the surface of the strip plate, with its length direction parallel to the strip plate. An inlet pipe extends outward from the cooling water pipe and communicates with the cooling water pipe cavity. An outlet pipe extends outward from the cooling water pipe along its length away from the inlet pipe and communicates with the cooling water pipe cavity. The components, including the cooling water pipe, inlet pipe, outlet pipe, strip plate, and arc-shaped groove, are integrally formed from elastic stainless steel. Attached Figure Description

[0013] As shown in the drawings, the fastening type sustainable heat dissipation cable of the utility model includes strip-shaped lower shell, the lower shell includes the half circular open pipeline 2 (the half circular angle is 180 DEG) which is axially front-back horizontal and radially open half circular shape, the half circular open pipeline 2 is vertically upwards arranged in the half circular opening, and the cable body 1 consistent with the length direction of the half circular open pipeline 2 is vertically downwards matched and embedded in the half circular open pipeline 2;
[0014] The top edge (i.e. the two side edges of the half circular opening) of the half circular open pipeline 2 is vertically upwards extended to the left and right, and the convex plate 3 parallel to the half circular open pipeline 2 is symmetrically arranged on the left and right sides of the top edge, and the convex plate 3 is a plate with vertical left and right surfaces and is horizontally outward curved in the radial direction.
[0015] The upper shell is arranged above the lower shell, and the upper shell includes a strip-shaped plate 4 with a length direction being front-back horizontal, and the upper and lower surfaces of the strip-shaped plate 4 are horizontally arranged, and the lower surface of the strip-shaped plate 4 is fixedly connected with an arc-shaped matching groove 5 (formed by vertically upwards recessing the central part of the lower surface of a plate-shaped body fixedly connected below the strip-shaped plate 4, and the arc angle is 120 DEG) parallel to the strip-shaped plate 4 in the axial direction, and the groove of the arc-shaped matching groove 5 is vertically downwards arranged, and the cable body 1 is vertically upwards matched and embedded in the arc-shaped matching groove 5.
[0016] The left and right sides of the strip-shaped plate 4 are vertically downwards extended to the left and right, and the connecting plate 8 parallel to the strip-shaped plate 4 in the length direction is symmetrically arranged on the left and right sides of the plate edge, and the left and right surfaces of the connecting plate 8 are vertically arranged, and the connecting plate 8 is locally horizontally outward curved in the radial direction to form the embedding groove 6 parallel to the connecting plate 8 in the length direction and having a horizontal inward groove, and the convex plate 3 is horizontally outward matched and filled in the corresponding embedding groove 6 on one side through the convex structure, so that the upper shell and the lower shell are matched and covered, and the cable body 1 is clamped by the groove wall of the arc-shaped matching groove 5 and the cavity wall of the half circular open pipeline 2, and the arc-shaped matching groove 5 horizontally outward abuts against the convex plate 3 on the left and right sides.
[0017] The upper surface of the strip-shaped plate 4 is fixedly connected with the cooling water pipe 7 parallel to the strip-shaped plate 4 in the length direction, the cooling water pipe 7 outward extends the water inlet pipe 71 connected with the cavity of the cooling water pipe 7, and the cooling water pipe 7 outward extends the water outlet pipe 72 connected with the cavity of the cooling water pipe 7 away from the water inlet pipe 71 along the length direction of the cooling water pipe 7, and the components including the cooling water pipe 7, the water inlet pipe 71, the water outlet pipe 72, the strip-shaped plate 4, the arc-shaped matching groove 5 and the connecting plate 8 are integrally formed of elastic stainless steel.
[0018] During assembly, first, the cable body 1 (an existing cable product with a layered structure including a metal conductor core, insulation layer, shielding layer, and outer sheath layer from the inside out) is fully inserted downwards and parallel into the semi-circular open pipe 2. Then, one end of the upper shell along its length is aligned as shown in the attached figure. Figure 2 After the structure is fitted and connected to one end of the semi-circular open pipe 2 along its length, the upper shell continues to slide along the length of the semi-circular open pipe 2 (and the cable body 1 on it) until it completely fits and covers the semi-circular open pipe 2 and the cable body 1 therein, thereby obtaining the cable product of this application.
[0019] During use, external water pipes are connected to the inlet pipe 71 and outlet pipe 72 respectively. Simultaneously, the other end of the external water pipe connected to the inlet pipe 71 is connected to the water supply equipment. When the cable body 1 overheats due to prolonged power transmission, water can continuously flow into the cooling water pipe 7 through the inlet pipe 71. The cold water flows along the length of the cooling water pipe 7 to the outlet pipe 72 and then flows out. Since the upper and lower shells are assembled together, the groove wall of the arc-shaped fitting groove 5 is in close contact with the cable body 1, providing a large contact area. Furthermore, because the arc-shaped fitting groove 5, the strip plate 4, and the cooling water pipe 7 are all integrally formed stainless steel components, they all have ideal heat transfer properties. The heat from the cable can be smoothly transferred to the cold water in the cooling water pipe 7 through the arc-shaped fitting groove 5 and the strip plate 4, and continuously carried out by the flowing cold water through the outlet pipe 72, achieving continuous cooling and heat dissipation for the cable body 1. It is evident that by introducing a low-cost water supply device as an auxiliary measure, this application can achieve safe, stable, and efficient long-term power supply for high-cost large-scale equipment, thus ensuring greater economic benefits.
[0020] In order to save water, the water flowing out of the outlet pipe 72 can be cooled naturally in the external environment and then circulated back into the cooling water pipe 7 according to the aforementioned path.
[0021] In terms of structural design, this application, through the design of the position and dimensions of the arc-shaped groove 5 (the plate-like body in which it is located, the same below), ensures that the convex plate 3 is horizontally inwardly abutted and supported by the arc-shaped groove 5. This further enables the convex plate 3 to be horizontally and stably fitted and pressed against the groove 6 on the same side through its own protruding structure (as shown in the attached figure). Figure 2 This not only facilitates the stable installation between the upper and lower shells of the cable, but also allows the grooves 6 on both sides to be simultaneously subjected to the aforementioned outward horizontal compressive support force. Through the force transmission within the integrally formed component consisting of the strip plate 4, the arc-shaped mating groove 5, and the connecting plate 8, the arc-shaped mating groove 5 is pressed down, which facilitates the stable surface-to-surface contact between the groove wall of the arc-shaped mating groove 5 and the cable body 1, thereby improving the efficiency of heat transfer from the cable body 1 to the cooling water pipe 7.
[0022] If the arcuate fitting groove 5 is not designed in this position and size (as in the attached Figure 3 ), it cannot ensure that the convex plate 3 can be horizontally and outwardly fitted and pressed in the embedding groove 6 through its convex structure, so that it cannot ensure that the arcuate fitting groove 5 and the cable body 1 can be effectively surface-contacted together through the force transmission inside the above-mentioned component, so that there is a gap between them (especially as in the attached Figure 3 , when the arcuate fitting groove 5 and the cable body 1 are not in the up-down relationship in the absolute height position, even the condition that the arcuate fitting groove 5 is downwardly surface-contacted and pressed on the outer surface of the cable body 1 based on gravity does not exist), so that the efficiency of heat transmission from the cable body 1 to the arcuate fitting groove 5 is affected.
