This can lead to overheating and frequency throttling during prolonged high-load operation, thus affecting performance. Simultaneously, consumers' demands for laptop portability are increasing, prompting manufacturers to continuously pursue thinner and lighter designs. However, thinner and lighter bodies mean further compression of heat dissipation space, making traditional air-cooling systems insufficient for cooling requirements. Utility Model Content

[0014] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0015] Example 1: A liquid cooling heat dissipation system for electronic devices includes: at least one inner liquid cooling plate 1 for thermally contacting a heat-generating element inside the electronic device, and a circulation pump 2 and a water cooling radiator 3 respectively disposed outside the electronic device; one end of a first inner conduit 41 is connected to the liquid outlet of the inner liquid cooling plate 1, and the other end of the first inner conduit 41 is connected to one end of a first outer conduit 61 through an adapter 5; the other end of the first outer conduit 61 is connected to the liquid inlet of the water cooling radiator 3; the other end of a second outer conduit 62, one end of which is connected to the liquid outlet of the water cooling radiator 3, is connected to the adapter 5; the circulation pump 2 is mounted on the second outer conduit 62; and the adapter 5 is connected to the liquid inlet of the inner liquid cooling plate 1 through the second inner conduit 42. The electronic device is internally provided with a first heat dissipation fin group 71 and a second heat dissipation fin group 72 that respectively cooperate with the first inner conduit 41 and the second inner conduit 42. The first inner conduit 41 and the second inner conduit 42, which are configured as flat tubes, each have at least one U-shaped segment 81. The areas of the first segment 82 and the second segment 83 located at both ends of the U-shaped segment 81 are parallel to each other and each has a bent portion 9 that fits against the end face of the corresponding first heat dissipation fin group 71 and the second heat dissipation fin group 72 away from the inner liquid cooling plate 1, so that the same side surface of the first inner conduit 41 and the second inner conduit 42 respectively fits and contacts the two side surfaces of the corresponding first heat dissipation fin group 71 and the second heat dissipation fin group 72.

[0016] The aforementioned adapter 5 is installed on the electronic device; the two aforementioned internal liquid cooling plates 1, which are connected in series via conduits, respectively make thermal contact with the CPU chip and GPU chip inside the electronic device. Two of the above-mentioned internal liquid cooling plates 1 are mounted on a base plate 12. The base plate 12 is provided with a plurality of mounting holes 121 spaced apart. A plurality of bolts 13 for connecting to electronic equipment pass through the corresponding mounting holes 121. A spring 14 is fitted on the outside of each bolt 13 and between the base plate 12 and the cap 131 of the bolt 13. This facilitates the installation of the internal liquid cooling plate and ensures the stability of the surface contact with the heat-generating components inside the electronic device, thereby ensuring the stability of heat conduction and heat dissipation.

[0017] After the external liquid cooling pipes are connected to the internal liquid cooling module of the electronic device (water cooling connectors are plugged in), the water inside the internal liquid cooling plate is heated by the CPU and GPU chips, and then enters the water cooling radiator driven by the circulating micro pump. Under the cooling of the axial fan, the cooled water enters the water tank for storage, and is then pumped into the liquid cooling module of the electronic device by the micro pump to form the final circulation.

[0018] Example 2: A liquid cooling heat dissipation system for electronic devices, comprising: at least one inner liquid cooling plate 1 for thermally contacting a heat-generating element inside the electronic device, and a circulation pump 2 and a water cooling radiator 3 respectively disposed outside the electronic device; one end of a first inner conduit 41 is connected to the liquid outlet of the inner liquid cooling plate 1, and the other end of the first inner conduit 41 is connected to one end of a first outer conduit 61 via an adapter 5; the other end of the first outer conduit 61 is connected to the liquid inlet of the water cooling radiator 3; the other end of a second outer conduit 62, one end of which is connected to the liquid outlet of the water cooling radiator 3, is connected to the adapter 5; the circulation pump 2 is mounted on the second outer conduit 62; and the adapter 5 is connected to the liquid inlet of the inner liquid cooling plate 1 via the second inner conduit 42. The electronic device is internally provided with a first heat dissipation fin group 71 and a second heat dissipation fin group 72 that respectively cooperate with the first inner conduit 41 and the second inner conduit 42. The first inner conduit 41 and the second inner conduit 42, which are configured as flat tubes, each have at least one U-shaped segment 81. The areas of the first segment 82 and the second segment 83 located at both ends of the U-shaped segment 81 are parallel to each other and each has a bent portion 9 that fits against the end face of the corresponding first heat dissipation fin group 71 and the second heat dissipation fin group 72 away from the inner liquid cooling plate 1, so that the same side surface of the first inner conduit 41 and the second inner conduit 42 respectively fits and contacts the two side surfaces of the corresponding first heat dissipation fin group 71 and the second heat dissipation fin group 72.

[0019] A fan 10 is installed on the outside of the aforementioned water-cooling radiator 3; the aforementioned first heat dissipation fin group 71 and second heat dissipation fin group 72 are respectively disposed on both sides of the inner liquid cooling plate 1; A water tank 11 is provided on the second external conduit 62 and located between the water cooling radiator 3 and the circulating pump 2. The water tank 11 is located above the circulating pump 2, which facilitates the initial injection and replenishment of liquid in the pipeline, eliminates the need for the circulating pump to self-prime, and facilitates the venting of gas in the pipeline, thereby improving the stability of various performance aspects during use.

[0020] The liquid cooling plate, circulating pump, and water cooling radiator can all be purchased externally and are within the scope of existing technology, so this application will not elaborate on them.

[0021] When the above-mentioned liquid cooling heat dissipation system for electronic devices is adopted, the liquid cooling pipelines that connect the inside and outside can greatly improve the heat dissipation performance of electronic devices and computers. At the same time, it can save internal space of electronic devices, increase the length of the liquid cooling pipelines and the contact area between them and the heat dissipation fins, thereby further improving the heat dissipation efficiency inside the electronic devices.
