Coolant diversion pipe is connected to multiple second channels by the second buffering accommodation space being formed in the second external connection end.
Due to multiple first passage 3a, the second channels to circulate for coolant being arranged in this example, held by the first buffering
Receive space 8a, second buffering accommodation space setting, can facilitate the first coolant diversion pipe 3b, the second coolant diversion pipe with
Channel（First passage 3a, second channel）It is connected to and then supplies enough coolants.
In this example, refrigeration cable further includes the temperature control line being located in outer layer protective sleeve 1 and for detecting internal temperature
Core 7.Specifically, temperature control conductor 7 has with positive power transmission core conductor 3, cathode power transmission core conductor 4 one by one
Corresponding two.
To sum up, the present invention is by being respectively formed at positive power transmission core conductor 3 and being coated on positive power transmission line
Between the first insulating protective layer 9 on core conductor 3, it is formed in cathode power transmission core conductor 4 and is coated on cathode power biography
The channel for coolant circulation between the second insulating protective layer in defeated cable core conductor 4, on the one hand realizes coolant and leads
Body（Positive power transmission core conductor 3, cathode power transmission core conductor 4）Be in direct contact, and then can temperature with high efficiency refrigeration,
On the other hand, since insulating layer is directly to be supported on the conductor being wrapped by, and channel is in conductor and corresponding insulating layer
Between formed, to when cable be bent or bend cabling during, the set-up mode in channel of the present invention can be to avoid cooling
Agent circulation area drastically reduces the coolant that in turn results in and forms high pressure and squeeze until the case where racking insulating layer occurs, and avoids
The generation of the unsafe conditions such as short circuit caused by insulating layer rupture.
Meanwhile in the present embodiment, the first passage 3a and the first coolant that are directed to positive power transmission core conductor 3 are led
Flow tube 3b forms one-to-one cooling duct, be directed to the second channel of cathode power transmission core conductor 4 and the second coolant is led
Flow tube forms one-to-one cooling duct, is equally beneficial for avoiding the generation of the dangerous situations such as short circuit.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention, all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
