  • Publication number: 20240074032
    Abstract: An outlet heat sink for a liquid cooling system for an electronic board, including a cold inlet connector, a hot inlet connector and a hot outlet connector. An upper part of a cooling block, on the one hand, conveys the flow of heat transfer fluid entering through the cold inlet connector to the lower part of the cooling block so as to collect heat generated by the electronic board by being conveyed to the hot outlet connector, and on the other hand, conveys the flow of heated-up heat transfer fluid received on the hot inlet connector directly to the hot outlet connector.

  • Publication number: 20240074101
    Abstract: An interlayer heat sink for a liquid cooling system for an electronic card, the interlayer heat sink including a cold inlet connector, a hot inlet connector, a hot outlet connector, and a cold outlet connector. An upper part of the cooling block divides the flow of heat transfer fluid entering through the cold inlet connector into a first flow, which is oriented towards the lower part of the cooling block so as to collect heat generated by the electronic card by being conveyed to the hot outlet connector, and a second flow, oriented directly to the cold outlet connector, to convey the flow of heated-up heat transfer fluid received on the hot inlet connector directly to the hot outlet connector where it fuses with the heated-up flow in the lower part of the cooling block.
