  • Publication number: 20180263138
    Abstract: A siphon-type heat dissipation device includes a first plate body, a second plate body and a working liquid. An accommodation space is formed between the first plate body and the second plate body. The working liquid is accumulated in a lower portion of the accommodation space. A heat source is attached on the siphon-type heat dissipation device. After a heat energy generated by the heat source is transferred into the working liquid, the heat energy is absorbed by the working liquid, so that a portion of the working liquid is vaporized into a working vapor. After the working vapor ascends to an upper portion of the accommodation space, the heat energy is dissipated to surroundings, and the working vapor is condensed and changed into the working liquid. The working liquid flows back to the lower portion of the accommodation space.

  • Publication number: 20180253126
    Abstract: A water-cooling heat dissipation module includes a hot-water heat exchange structure, a cold-water heat exchange structure, a fluid communication structure and a fan. The fluid communication structure is in communication with the hot-water heat exchange structure and the cold-water heat exchange structure. The fan and the hot-water heat exchange structure are opposed to each other with respect to the cold-water heat exchange structure. An airflow produced by the fan blows the cold-water heat exchange structure and the hot-water heat exchange structure sequentially. Consequently, the cold-water heat exchange structure will not receive the heat from the hot-water heat exchange structure through the airflow.

  • Publication number: 20180255662
    Abstract: An electronic device with a heat-dissipating function and a liquid-cooling radiator module are provided. The electronic device includes a first circuit board, a second circuit board and a liquid-cooling radiator module. The second circuit board is mounted on the first circuit board. The liquid-cooling radiator module is attached on the second circuit board and in thermal contact with an electronic component of the second circuit board. The liquid-cooling radiator module includes plural airflow channels and a fan. The plural airflow channels are in parallel with the second circuit board. The fan produces airflow toward the plural airflow channel. After the airflow passes through the plural airflow channels, the airflow is outputted in a direction parallel with the second circuit board. Since the airflow is not obstructed by the adjacent function circuit boards, the heat-dissipating efficiency is enhanced.

  • Publication number: 20180213677
    Abstract: A liquid-cooling heat dissipation device includes a thermally conductive base and a covering structure. The thermally conductive base has a bottom surface and a top surface opposed to the bottom surface. The bottom surface is in contact with a heat source. A heat dissipation structure is formed on the top surface. The thermally conductive base is covered by the covering structure. An input chamber and an output chamber are defined by the thermally conductive base and the covering structure collaboratively. The input chamber is disposed over the heat dissipation structure and has an entrance. The output chamber has an exit. The input chamber is a tapered space. A vertical height of the input chamber is gradually decreased in a direction from the entrance toward the exit. Consequently, liquid flowing into the input chamber through the entrance is guided to the heat dissipation structure.
