Description

Technical Field

[0001] The utility model relates to the technical field of cable heat dissipation, in particular to a cooling structure for cable heat dissipation. Background Art

[0002] Cable is a collection of conductive materials used to transmit electricity, communication signals or data. It is usually composed of one or more insulated wires and wrapped in a protective layer. They are usually used to connect power, communication and data networks in electrical equipment, buildings and other structures. In daily life, cables can be seen everywhere and have become an indispensable component.

[0003] In construction and industrial applications, there are the following usage scenarios: one is that the power of the electrical appliances connected to the cable itself is large, and the cable itself generates heat due to long-term uninterrupted use; the other is that a specific cable is exposed to the external environment for a long time in hot weather, causing the cable to be in a high-heat scene. Regardless of the usage scenario, it is necessary to dissipate heat to extend the service life and ensure the normal operation of signals and electrical equipment. Therefore, a cooling design structure for cable heat dissipation should be introduced.

[0004] The existing cable heat dissipation method mainly achieves heat dissipation by the material itself, which can meet the normal cable life under normal use in normal environments. In construction and industrial applications of high-power electrical appliances and high-heat scenarios, an external cooling device can be used for coolant cooling. However, in the existing cooling and heat dissipation process, the flow rate cannot be adjusted. If the flow rate is too slow, heat evaporation and vaporization will affect the protection of the cable jacket. If the flow rate is too fast, a continuous coolant output is required, affecting the power output of the external cooling equipment. Therefore, it is necessary to make structural design improvements to the cable itself to meet the requirements of regulating the appropriate flow rate of the coolant to cope with different application scenarios.

The support layer 7 is first prepared from a carbon fiber plastic composite material, and its main function is to utilize its high strength, low weight and excellent environmental resistance to serve as a support for the connection between the cable body 1 and the hollow heat dissipation sleeve 2. At the same time, through holes 8 are distributed on the support layer 7, and the through holes 8 allow the coolant to flow in the channel between the cable body 1 and the hollow heat dissipation sleeve 2.

[0026] On the basis of the supporting layer 7, the hollow heat dissipation sleeve 2 and the transverse section of the cable body 1 are also filled with a barrier layer 3, the barrier layer 3 is made of polyethylene, or polypropylene, or polytetrafluoroethylene, and a notch 4 is provided on the barrier layer 3, the notch 4 extends to the inner wall of the hollow heat dissipation sleeve 2, and a screw hole 5 is provided on the hollow heat dissipation sleeve 2, the screw hole 5 is connected with the notch 4, and the inner surface of the notch 4 is provided with a semi-arc threaded portion 6, this technology can be inserted or removed through a screw connection by a screw, specifically, the threaded portion 6 at the inner surface of the notch 4 is semi-arc, that is, the front and back are connected, and the side threaded portion 6 is assembled with the screw, so as to realize the adjustment of the caliber size of the front and back connection at the notch 4, thereby controlling the flow rate in the channel, specifically, there are four groups of notches 4 in the barrier layer 3, which are arranged equidistantly in the circumferential direction, and the barrier layer 3 is provided in multiple groups, and the array is provided at the transverse section of the hollow heat dissipation sleeve 2 and the cable body 1, this design is convenient for multiple adjustment of the size of the notch, and is suitable for operation by staff.
