A plurality of hard support rings 9 are axially arranged on the side, an outer shielding layer 10 is arranged on the outer side of the outer waterproof membrane 7, an outer sheath 11 is coated on the outer side of the outer shielding layer 10, the inner side of the cavity 8 is filled with coolant, connecting rings 12 for connecting to a water pump are arranged at both ends of the cable, two connecting ports 1201 are symmetrically arranged on the connecting ring 12, and the two connecting ports 1201 are respectively a water inlet and a water outlet, the connecting ring 12 is fixed at both ends of the cable and the cable structure located on the inner sheath 5 and the inner side thereof all pass through the central hole of the connecting ring 12.

[0024] As an implementation manner, the inner waterproof membrane 6 and the outer waterproof membrane 7 both include two layers of superimposed polyester films.

[0025] As an implementation manner, the polyester film of the inner waterproof membrane 6 is bonded to the inner protective layer 5 .

[0026] As an implementation manner, the outer shielding layer 10 is a metal sleeve, and the polyester film of the outer waterproof membrane 7 is bonded to the metal sleeve.

The data transmission cable of the utility model is suitable for data transmission between two data storage units. Usually, the distance between the two data storage units is long. By arranging water pumps at both ends of the cable, the coolant inside the cable can circulate.
