[0021] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0022] Referring to Figures 1-3 A liquid cooling pipe integrated with FPC temperature acquisition harness, comprising a pipe body 1, a plurality of mounting holes 2 are arranged on the side of the pipe body 1 in a spiral manner, a flexible circuit board 3 (FPC) is spirally wound on the outer side of the pipe body 1, a plurality of thermistors 4 are fixedly connected to the flexible circuit board 3, one end of the thermistor 4 extends into the mounting hole 2, a metal braid layer 5 is fixedly sleeved on the outer side of the flexible circuit board 3, an outer protective layer 6 is fixedly sleeved on the outer side of the metal braid layer 5, and an inner protective layer 7 is arranged between the metal braid layer 5 and the pipe body 1.

[0023] The liquid cooling pipe of the integrated FPC temperature acquisition harness, in production, firstly spirally winds the flexible circuit board 3 on the side of the pipe body 1, and then inserts the thermistor 4 into the mounting hole 2. After completion, the rubber sol is covered on the outer side of the liquid cooling pipe, and after the rubber sol is solidified into the inner protective layer 7, the metal braided layer 5 is sleeved outside the inner protective layer 7, and then the outer protective layer 6 is sleeved outside the metal braided layer 5.

[0024] In use, the cooling liquid flows in the liquid cooling pipe, the thermistor 4 is subjected to temperature change, and the resistance value changes accordingly, that is, the temperature monitoring of the cooling liquid in the liquid cooling pipe can be realized. After removing the extreme value, the average temperature can more accurately reflect the temperature of the cooling liquid in the liquid cooling pipe.

[0025] The thermistor 4 is an NTC thermistor, which can more accurately measure the temperature and improve the temperature measurement accuracy of the device compared with a PTC thermistor.

[0026] In order to avoid that the mounting hole 2 deviates too much angle, resulting in that only the temperature of the two sides inside the pipe body 1 can be detected, the offset angle of the adjacent mounting hole 2 on the pipe body 1 is not more than 120°, which can measure the temperature of at least three sides inside the pipe body 1, thereby improving the temperature measurement uniformity and stability. The subsequent scheme with an offset angle of 90° is described, since the mounting hole 2 is one-to-one corresponding to the thermistor 4 and the sealing ring and the convex ring, as shown in Figure 2 , the temperature in four directions of the liquid cooling pipe can be measured.

[0027] Referring to Figures 1-3 , a plurality of sealing rings 8 are fixedly connected to the outer side of the thermistor 4 on the flexible circuit board 3, and the sealing ring 8 is fitted to the mounting hole 2. The sealing ring 8 realizes sealing of the mounting hole 2, avoids that the rubber sol enters the mounting hole 2 when the inner protective layer 7 is set, affects the liquid cooling effect, and improves the stability of the device.

[0028] Since the flexible circuit board 3 may be interfered by external force when the rubber sol is coated, the sealing ring 8 is away from the thermistor 4 and the mounting hole 2, and the side away from the flexible circuit board 3 of the sealing ring 8 extends outwardly and is provided with a convex ring 9. The convex ring 9 cooperates with the mounting hole 2 to limit the flexible circuit board 3, thereby improving the production practicability of the device.

[0029] In order to further improve the production practicability of the device, the pipe body 1 is fixedly connected with a clamping block 10 for cooperating with the flexible circuit board 3. The clamping block 10 limits the flexible circuit board 3, thereby improving the winding stability of the flexible circuit board 3.

[0030] The inner protective layer 7 is a thermoplastic soft rubber. After the rubber is solidified, it becomes a filling inner protective layer 7, which provides buffering and protection for the liquid cooling pipe and the FPC.

[0031] The outer protective layer 6 is a PET heat shrink sleeve, after the outer protective layer 6 is sleeved outside the metal braid layer 5, the heat shrink sleeve is shrunk by a hot air machine, so that the metal braid layer 5 is tightened, and the device stability is improved.

[0032] The metal braid layer 5 is made of copper or steel, the metal braid layer 5 made of copper or steel can provide electromagnetic shielding for the FPC, external interference is avoided, and the anti-interference capability is improved, in addition, the metal braid layer 5 can also improve the mechanical strength of the liquid cooling pipe, and improve the service life and stability.

[0033] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art in the technical range disclosed by the present application, according to the technical scheme and the utility model concept of the present application, equivalent replacement or change, should be covered in the protection scope of the present application.
