  • Patent number: 10945352
    Abstract: A cooling device of a heating element for an immersion type liquid cooling server, and a manufacturing method for the cooling device. The cooling device comprises: a metal substrate provided on the heating element and covering same. The metal substrate is adjacent to the surface of the heating element. The surface of the metal substrate distant to the heating element comprises a porous metal covering layer located above the heating element and covering same. The porous metal covering layer is exposed on the surface of the metal substrate remote from the heating element and has a thickness of less than 3 mm. By providing a metal substrate having a porous metal covering layer on the surface of a heating element, vaporization cores are improved, the boiling performance of the heating element is improved, and an efficient heat-dissipating effect on the surface of the heating element is achieved.

  • Patent number: 10863650
    Abstract: The present invention relates to an air-vapor separation method for separating air from refrigerant vapor in an immersed liquid-cooling system. The immersed liquid-cooling system comprises an immersed server blade cabinet, a condensing device, an air-vapor separator and a refrigerant storage tank, wherein the refrigerant storage tank supplies a liquid refrigerant to the immersed server blade cabinet, and the liquid refrigerant undergoes a phase change to be vaporized into a refrigerant vapor for cooling of the heating element in the immersed server blade cabinet; the condensing device condenses the refrigerant vapor; the air-vapor separator separates a mixed gas in the immersed liquid-cooling system into the air and the refrigerant vapor. The cooling efficiency of the liquid-cooling system is improved by effectively separating the air from the refrigerant vapor in the liquid-cooling system.

  • Patent number: 10338813
    Abstract: The present invention provides a storage controller and a using method therefor. The method comprises: processors send a storage instruction; a processor controller receives the storage instructions sent by the processors, and sends the storage instructions to an exchanger; the exchanger sends the storage instructions to a hard disk controller one by one; and the hard disk controller sends the storage instructions to a hard disk according to storage address spaces indicated in the storage instructions, the indicated address spaces being address spaces allocated to the processors sending the storage instructions. By using the technical scheme of the present invention, multiplexing of the same physical storage space for the storage instructions of multiple processors can be ensured in a time-sharing mechanism, and accordingly, a purpose that the multiple processors share the same physical storage space by means of hardware is achieved.
