Degree cannot control temperature range in restriction, and the heat of conductor generation may cause insulating materials to be degenerated, cause cable damage and
The security incidents such as fire.The major way of control conductor temperature is to increase conductor area to reduce cable transmission resistance at present, so
And the increase of conductor material and insulating materials and cable weight will necessarily be brought, this is that human body is undesirable.
It is more and more to transmit the use occasion of high current power cable, such as high-power main frequency furnace is former by electromagnetic induction
Reason generates higher temperature to generate larger current with the electric current, melts metal, achievees the purpose that smelting；The operation of main frequency furnace
Must electric power be accessed by cable, larger current is certainly existed in the cable, generate higher heat and temperature.It is led in new-energy automobile
Domain, charging rate are an important factor for influencing New-energy electric vehicle development, and high current high-voltage cable is following development side
To, though high-power charging can significantly shorten the charging time, high current is high-power to also bring along electric cable heating and high temperature rise,
Excessively high cable temperature can not only melt insulation and the sheath of cable, accelerate the aging of cable insulation or sheath, make insulation or shield
Covering original electrical property and mechanical performance reduces or even can burn out cable conductor, and the person and equipment belt are damaged.How to solve
The heat dissipation problem of high current power cable, has had been to be concerned by more and more people.
Utility model content
Problem to be solved by this invention be to provide it is a kind of can effectively control cable Wen Sheng, ensure cable longtime running dissipate
Thermopower cable.
In order to solve the above-mentioned technical problem, the heat dissipation power cable of the utility model including cable core and is coated on cable core
Outer the coat layer of power cable, the cable core, which includes at least, two groups of radiation conductive units, and cable core is filled between radiation conductive unit
Packing；The radiation conductive unit includes conductor and the insulating layer of conductor being coated on conductor, is set in the core of conductor
There is radiation cooled tube, cooling pipe insulation layer is coated in the radiation cooled tube.
With the above structure, due to being equipped with radiation conductive unit in cable core, the conductor core of heat-sink unit is then equipped with
Radiation cooled tube, passed in radiation cooled tube coolant can big flow, fast speed area walk power cable conductor electric power biography
Heat caused by during defeated ensures that cable can work normally steadily in the long term；Radiation cooled tube is located at conductor cores position
It puts and is not only more advantageous to taking away cable conductor heat, and structure is more reasonable, convenient for manufacturing for cable.Again due to dissipating
It can be ensured that the rounding property of cable conductor filled with cable core packing, the one side packing between thermal conductivity electric unit, make cable knot
Structure becomes more stable, and on the other hand by packing and the contacting directly on the outside of cable conductor of radiating, strengthens and cable is led
The heat dissipation effect of body so as to which cooling is radiated while formation to cable conductor outside and core, there is significantly more efficient cable to dissipate
Hot cooling effect has efficiently controlled cable Wen Sheng, it is ensured that the long-term efficient operation of cable.
The preferred embodiment of the utility model, the radiation cooled tube are corrugated flexible hose.It can using bellows structure
Increase the flexibility of cable, and coolant can be made to form vortex in flowing, so as to improve heat dissipation effect.
The preferred embodiment of the utility model, the cooling pipe insulation layer is Silicone Rubber Inhibitor.Using silicon rubber bag
Coating can effectively improve the stability of cable electric property in a high temperauture environment, and anti-aging property protrudes, beneficial to ensureing cable
Long-term stable operation.
The preferred embodiment of the utility model, the cable core include three groups of radiation conductive units, in three groups of heat dissipations
Three cable core packings are filled between conductive unit.The construction of cable can realize that three-phase power transmits well.
The preferred embodiment of the utility model, on the cable core packing perforation along its length be provided with packing and dissipate
Hot hole.Packing heat emission hole there are three being set on the cable core packing.Thermal vias on packing is set, can effectively improve and fill out
Fill the heat dissipation effect of item.
