Description

Technical Field

[0001] This utility model relates to a cable processing equipment, and more particularly to a cable cooling device. Background Technology

[0002] Cables are the core carriers for transmitting electrical energy or signals. During the cable processing, the raw material of the outer sheath needs to be extruded through a high-temperature extrusion device and wrapped around the outside of the cable core. The wrapped cable needs to be cooled, and the cooled cable is then combined with other materials or wound up as required.

[0003] Traditional cables pass through a water-filled chamber during the cooling stage to dissipate heat from the newly sheathed cable into the water. To improve cooling efficiency, the water in the chamber is kept flowing. However, because the cable needs to maintain a certain tension during transmission, only the upper part of the liquid surface heats up when in contact with the cooling water, while the lower part cools down more slowly. This results in some heat loss during cooling water circulation, and the water temperature in the chamber gradually rises, leading to a gradual decrease in overall cooling effectiveness.

[0004] Therefore, this invention aims to provide a cable cooling device that can maintain sufficient transmission tension of the cable while achieving timely cooling, and can separately treat the upper liquid surface of the cooling water to reduce the temperature of the entire cavity. Utility Model Content

[0005] This invention provides a cable cooling device that can effectively solve the above-mentioned problems.

[0006] This utility model is implemented as follows:

[0007] A cable cooling device includes: a water-containing chamber, with an inlet and an outlet respectively provided at both ends of the water-containing chamber, the water-containing chamber being connected to at least one water inlet, and further comprising:

[0008] The cold transfer structure includes several cold transfer rollers arranged in a water-filled chamber. The cold transfer rollers are hollow and contain refrigerant. The upper end of the cold transfer rollers is provided with an upper spraying component.

[0009] The internal circulation structure includes an internal circulation trough located at the bottom of the cold transfer roller, and the projected positions of the cold transfer roller and the upper spraying component are both located within the range of the internal circulation trough.

[0010] As a further improvement, the cold transfer roller includes a refrigerant inlet and a refrigerant outlet inserted into a water-filled chamber, with a refrigerant cylinder connected between the refrigerant inlet and the refrigerant outlet. The refrigerant cylinder has an inwardly recessed inner annular groove in its middle section, which is used to accommodate a cable.

[0011] As a further improvement, the refrigerant inlet and refrigerant outlet are rotating structures, and the refrigerant inlet or refrigerant outlet is connected to a rotating component.

[0012] As a further improvement, the upper spraying component includes a circulation pipe connected to the bottom of the water-filled chamber, the circulation pipe being connected to a mounting base, the mounting base having a plurality of mounting groups facing the water-filled chamber.

[0013] As a further improvement, the mounting assembly includes a large through hole located in the center of the bottom surface of the mounting base, and small through holes located on both sides of the bottom surface of the mounting base.

[0014] As a further improvement, the rotating structure includes a rotary joint disposed at the refrigerant inlet and refrigerant outlet, the rotary joint being connected to an external extension pipe that connects to an external refrigerant pipeline.

[0015] As a further improvement, the upper guide ring includes an mounting arm installed inside the water-filled cavity, and an arched infiltration tile is installed between the two mounting arms, the infiltration tile having a plurality of infiltration holes.

[0016] The beneficial effects of this utility model are:

[0017] In existing systems, only the temperature of the upper part of the liquid surface rises when in contact with cooling water, while the temperature of the lower part changes more slowly. This results in some heat loss during the circulation of cooling water. Therefore, this invention uses a cold transfer structure to allow the cable to pass through a cold transfer roller during transmission. The cable is cooled layer by layer by the refrigerant in the cold transfer roller, thereby achieving a localized rapid cooling effect. The heat is carried away by itself and does not remain in the upper part.

[0018] This invention also houses both the cold transfer roller and the upper spraying component in the inner circulation tank, thereby ensuring that heat is temporarily retained in an internal space and that the upper spraying component draws out only the colder water from the bottom, thus ensuring that there is heat flow while the cooling capacity is sufficient.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] Reference Figures 1-4As shown, a cable cooling device includes: a water-filled chamber 10, with an inlet end 11 and an outlet end 12 respectively provided at both ends of the water-filled chamber 10, and the water-filled chamber 10 is connected to at least one water inlet end 13; it also includes: a cold transfer structure 20, comprising a plurality of cold transfer rollers 21 arranged in the water-filled chamber 10, the cold transfer rollers 21 being hollow and containing a refrigerant, and an upper spraying component 22 being provided at the upper end of the cold transfer rollers 21; and an inner circulation structure 30, comprising an inner circulation trough 31 located at the bottom of the cold transfer rollers 21, the projected positions of the cold transfer rollers 21 and the upper spraying component 22 being located within the range of the inner circulation trough 31.

[0029] The cable that has just been coated with rubber has a certain temperature. In this embodiment, the cable that has just been coated with rubber is passed into the water-filled chamber 10 through the inlet end 11 and comes into contact with the cold transfer roller 21 in the water-filled chamber 10. Finally, it is output from the outlet end 12.

[0030] In existing systems, only the temperature of the upper part of the liquid surface rises when in contact with cooling water, while the temperature of the lower part changes more slowly. This results in some heat loss during the circulation of cooling water. Therefore, this invention uses a cold transfer structure 20 to ensure that the cable passes through a cold transfer roller 21 during transmission. The cable is cooled layer by layer by the refrigerant in the cold transfer roller 21, thereby achieving a localized rapid cooling effect. The heat is carried away by itself and does not remain in the upper part.

[0031] During the cooling process of the cold transfer roller 21, specifically, the cold transfer roller 21 includes a refrigerant inlet end 211 and a refrigerant outlet end 212 inserted into the water-filled chamber 10. A refrigerant cylinder 213 is connected between the refrigerant inlet end 211 and the refrigerant outlet end 212. The refrigerant cylinder 213 has an inner annular groove 214 recessed inward in the middle. The inner annular groove 214 is used to accommodate the cable, so that the refrigerant input through the refrigerant inlet end 211 can cool the cable when the cable passes through the inner annular groove 214. The inner annular groove 214 can also support the cable.

[0032] To ensure full utilization of the refrigerant, the refrigerant inlet 211 and refrigerant outlet 212 are rotating structures. The refrigerant inlet 211 or refrigerant outlet 212 is connected to a rotating component 215. Specifically, the rotating structure includes a rotary joint 2161 disposed on the refrigerant inlet 211 and refrigerant outlet 212. The rotary joint 2161 is connected to an external extension pipe 2162, which is connected to an external refrigerant pipeline. Thus, the refrigerant can be input or discharged through the external extension pipe 2162 and the rotary joint 2161 without affecting the normal rotation of the rotating component 215. In this embodiment, the rotating component 215 is a rotary motor.

[0033] When the cable passes through the cold transfer roller 21, the top spraying component 22 will work synchronously. Specifically, the top spraying component 22 includes a circulation pipe 221 connected to the bottom of the water-filled chamber 10. The circulation pipe 221 is connected to a mounting base 222. The mounting base 222 has several mounting groups 223 facing the water-filled chamber 10, which can realize the effect of heat dissipation in water and top-up cold source renewal.

[0034] During installation, the installation group 223 includes a large through hole 2231 located in the middle of the bottom surface of the installation base 222, and small through holes 2232 located on both sides of the bottom surface of the installation base 222. Most of the installation liquid is concentrated through the large through hole 2231 at the location where the cable passes through the middle, thereby ensuring that the temperature in the middle is relatively low.

[0035] In this embodiment, both the cold transfer roller 21 and the upper spraying component 22 are housed in the inner circulation tank 31, thereby ensuring that heat is temporarily retained in an internal space and that the upper spraying component 22 draws out water that is colder at the bottom, thus ensuring that there is heat flow while the cooling capacity is sufficient.

[0036] Furthermore, this embodiment also includes an upper guide ring 40 comprising an installation arm 41 installed inside the water-holding chamber 10, and an arched infiltration tile 42 installed between the two installation arms 41. The infiltration tile 42 has several infiltration holes 43, so that the water with a lower temperature deployed by the deployment group 223 can infiltrate into the infiltration tile 42 through the infiltration holes 43. It should be emphasized that the infiltration tile 42 is slightly exposed above the water surface to ensure the guiding effect of the water flow.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
