[0021] The present application will now be described in further detail with reference to the drawings. These drawings are simplified schematic diagrams which only show the basic structure of the present application in a schematic manner, and thus only show the components relevant to the present application.

[0022] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "connected", "connection" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0023] Figure 1 、 Figure 2 and Figure 3 A computer cable with end flow guiding cooling mechanism as shown in the figure, comprising a cable body, the cable body from inside to outside by conductor core 1, conductor insulation 2, conductor shield 3, filling layer 4, inner sheath 5, sheath insulation layer 6, insulation shield layer 7 and outer sheath 8, one end of the outer sheath 8 has an inner side connecting terminal 9, the other end of the outer sheath 8 has an outer side connecting terminal 10, the inner side of the inner sheath 5 is wound with an inner layer heat conducting pipe 11, and the inner side of the outer sheath 8 is provided with an outer layer heat conducting pipe 12.

[0024] In order to cooperate with the series connection of both ends, the inner side of the outer side connecting terminal 10 is provided with a first flow guiding chamber 13, and the inner side of the inner side connecting terminal 9 is provided with a second flow guiding chamber 14 for series connection of the inner layer heat conducting pipe 11 and the outer layer heat conducting pipe 12.

[0025] The first flow guiding chamber 13 is internally provided with an electrically controlled flow guiding liquid pump 15 for flow guiding.

[0026] In order to cooperate with the internal series flow guiding, the arc-shaped inner wall of the first flow guiding chamber 13 is provided with an outer flow guiding groove in communication with the inner layer heat conducting pipe 11, and the flat inner wall of the first flow guiding chamber 13 is provided with a flow guiding groove in communication with the outer layer heat conducting pipe 12.

[0027] The heat exchange medium inside the inner heat conducting pipe 11 is introduced into the first flow guide chamber 13 through the external flow guide groove, then introduced into the inner part of the outer heat conducting pipe 12 through the flow guide groove, and then returned to the inner part of the inner heat conducting pipe 11 through the second flow guide chamber 14.

[0028] In order to cooperate with the electric control rotation, the electric control flow guide liquid pump 15 includes an annular silent motor 151 installed inside the first flow guide chamber 13 and an external control sleeve 152 sleeved outside the annular silent motor 151 and a curved blade 153 fixed on the outer side surface of the external control sleeve 152.

[0029] The annular silent motor 151 is synchronously powered by the electrically conductive terminal connected with the external connection terminal 10, and can be synchronously operated when starting.

[0030] In order to monitor the temperature inside the flow channel, an embedded temperature sensor 16 is installed on the inner side surface of the first flow guide chamber 13.

[0031] In order to facilitate internal cleaning, an arc-shaped external maintenance opening is formed on the outer side surface of the external connection terminal 10 and is in communication with the inside of the first flow guide chamber 13.

[0032] In order to cooperate with the later maintenance, an arc-shaped external sealing cover plate 17 is fixedly installed inside the arc-shaped external maintenance opening.

[0033] In order to cooperate with the internal filtration, a detachable metal filter screen 171 is installed inside the arc-shaped external sealing cover plate 17.

[0034] When the arc-shaped external sealing cover plate 17 is covered inside the arc-shaped external maintenance opening, the detachable metal filter screen 171 will be closed at the flow guide groove opening at this time, and the internal heat exchange medium will be filtered by the detachable metal filter screen 171.

[0035] In order to facilitate the monitoring of the internal pressure, a pressure sensor module 18 is installed inside the first flow guide chamber 13.

[0036] Working process After the cable laying and connection are completed, the closed channel formed by the first flow guide chamber 13, the second flow guide chamber 14, the inner heat conducting pipe 11 and the outer heat conducting pipe 12 is injected with sufficient heat exchange medium; the arc-shaped external sealing cover plate 17 is installed in place, and the detachable metal filter screen 171 is in a filtering state; the embedded temperature sensor 16 and the pressure sensor module 18 start self-checking, and the electric control flow guide liquid pump 15 is in a low-power standby state; when the cable is not powered on, all components remain stationary, the heat dissipation system does not work, and energy consumption is saved.

[0037] When the cable is powered on and operated, the conductor core wire 1 generates heat and transmits it outward: Heat is transferred to the inner layer of heat pipe 11 through the inner sheath 5, heating the heat exchange medium in the pipe; the embedded temperature sensor 16 monitors the temperature of the medium in the first flow chamber 13 in real time, and the data is transmitted to the built-in control unit.

[0038] When the temperature rises to the preset starting threshold, the control unit instructs the annular silent motor 151 to start, driving the external control sleeve 152 and the curved blade 153 to rotate at high speed, generating driving force to push the heat exchange medium to flow in the circulation channel; the pressure sensor module 18 synchronously monitors the pressure to ensure that the channel is sealed and leak-free.

[0039] If the ambient temperature is low or the cable load is small, the medium temperature does not reach the threshold, and the electrically controlled flow guide liquid pump 15 remains on standby, relying only on natural heat dissipation to achieve "on-demand start".

[0040] The heat exchange medium circulates along the preset path under the drive of the electrically controlled flow guide liquid pump 15: from the first flow chamber 13 through the external flow guide groove into the inner layer of the heat pipe 11, the temperature rises after absorbing the heat inside the cable; the high-temperature medium flows into the outer layer of the heat pipe 12 through the second flow chamber 14, and exchanges heat with the outer sheath 8 to dissipate heat to the external environment, and the medium temperature decreases; the low-temperature medium flows back to the first flow chamber 13 through the flow guide groove, completing a heat dissipation cycle.

[0041] During the circulation process, the detachable metal filter screen 171 continuously filters impurities in the medium to prevent pipe blockage; the embedded temperature sensor 16 feeds back temperature data in real time, and the control unit dynamically adjusts the speed of the annular silent motor 151: the higher the temperature, the faster the speed, the faster the medium flow speed, and the higher the heat dissipation efficiency; when the temperature drops to the safety threshold, the speed is reduced to maintain basic circulation.

[0042] If there is a leak in the circulation channel, the pressure sensor module 18 detects a sudden drop in pressure and immediately sends an alarm signal to the external monitoring terminal, while the control unit instructs the electrically controlled flow guide liquid pump 15 to stop to prevent continuous loss of medium; after receiving the alarm, the operator promptly checks the leakage point and repairs it.

[0043] During regular maintenance, the operator removes the arc-shaped external sealing cover plate 17 and removes the detachable metal filter screen 171 for cleaning or replacement; the inside of the first flow chamber 13 is checked through the arc-shaped external maintenance opening to supplement or replace the deteriorated heat exchange medium; after cleaning, the arc-shaped external sealing cover plate 17 is reinstalled to ensure that the channel is sealed and the equipment returns to normal operation.

[0044] Based on the above ideal embodiments according to the present application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the contents of the specification, and the technical scope must be determined according to the scope of the claims.
