Description
Technical field
The present invention relates to cable, specifically a kind of flexible cable of new-energy automobile, particularly a kind of new-energy automobile car
The high-voltage flexible cable of load.
Background technology
Rechargeable vehicle is as a kind of new-energy automobile, and it has the unrivaled power savings advantages of conventional fuel oil automobile, is not
Carry out the trend of the times of development of automobile.In recent years, new energy Rechargeable vehicle quickly grow, market penetration rate it is higher.
Although new energy Rechargeable vehicle has many advantages in energy-saving square face, the major technique bottle of its Popularization And Development is limited
Neck is how to ensure its power source reliability of operation and stability.Improve the reliable of new energy Rechargeable vehicle power source operation
Property and stability, it is necessary to new energy Rechargeable vehicle must have the electricity such as battery, high-tension motor and controller of larger capacity
Supply of electric power between gas equipment, these electrical equipments is accomplished by corresponding high-tension cable to connect, i.e. on-board high-voltage flexible cable.
At present, the high-voltage flexible cable of new energy Rechargeable vehicle is common high-tension cable, and it is mainly by from inside to outside
The single copper conductor that is coated togather successively, insulating barrier, screen layer and restrictive coating composition, and restrictive coating generally using plastics into
Type.In actual use, the temperature designed on the conductor of its on-board high-voltage flexible cable is typically up to new energy Rechargeable vehicle
More than 120 DEG C, and high-voltage flexible cable in the car be in relative closed environment in；In this way, the body hair of on-board high-voltage flexible cable
Heat is serious and heat dissipation environment is bad so that the temperature of insulating barrier outer surface is up to 100 DEG C, is ultimately applied on restrictive coating
Temperature is up to 80~90 DEG C, this easily cause cable in itself or environment inside car local temperature it is too high, and then cause fire so that
Apply the existing high-voltage flexible cable on new-energy automobile that there is larger potential safety hazard.
Radiating deficiency, the technical problem of easy initiation potential safety hazard present in above-mentioned high-voltage flexible cable, it is difficult to simply
Moulding material is replaced（Including fire proofing）To solve, best settling mode is that innovation is made to the molding structure of cable, is changed
Become, so that the cooling medium including air carries out pressure cooling and realizes excellent heat dispersion, finally ensure that new energy fills
Electric car power source reliability of operation and stability.
However, making a general survey of cable industry, so far there are no can be applied to new-energy automobile, it is with forced heat radiation refrigerating function
Cable comes out.In published Chinese patent literature, have and be disclosed applied to the hollow self-cooled cable technology of skyscraper, example
Such as entitled " hollow self-cooled cable "（Publication number：CN 101546626, publication date：On September 30th, 2009）, " a kind of high level is built
Build the cooling cable certainly of distribution system "（Publication number：CN 202796208, publication date：On March 13rd, 2013）Technology；These
Although technology is that cooling medium-air is introduced in cable to realize cooling down certainly for cable forced heat radiation, i.e., they are hollow
Conductor in hollow metal tube is set, make the hollow formation coolant guiding channel of metal tube, to realize the cooling of conductor radiating.
But, such self-cooled cable does not only exist that contoured cross-section is big, structural volume is big, difficulty of processing is big, conductor consumptive material is more, processing cost
High technical problem, is not suitable for the compact new energy Rechargeable vehicle of accommodation space；Moreover, they are only capable of by hollow metal
The heart radiates pipe to conductor in the conductor, it is impossible to directly, effectively and reliably disperse the direct radiation effects of conductor on the insulating layer
Heat, that is to say, that the outer institute's coated insulation layer of conductor to bear heat still higher, and insulating barrier radiation effects is in overcoat
（Or restrictive coating）On temperature it is also still higher, it is seen then that the radiating of these technologies, self cooling result are limited, dependable with function
It is more inadequate.
