  • Publication number: 20240314976
    Abstract: A fluid immersion cooling system includes a fluid tank that contains a layer of a dual-phase coolant fluid and one or more layers of single-phase coolant fluids. The dual-phase and single-phase coolant fluids are immiscible, with the dual-phase coolant fluid having a lower boiling point and higher density than a single-phase coolant fluid. A substrate of an electronic system is submerged in the tank such that high heat-generating components are immersed at least in the layer of the dual-phase coolant fluid. Heat from the components is dissipated to the dual-phase coolant fluid to generate vapor bubbles of the dual-phase coolant fluid. The vapor bubbles rise to a layer of a single-phase coolant fluid that is above the layer of the dual-phase coolant fluid. The vapor bubbles condense to droplets of the dual-phase coolant fluid. The droplets fall down into the layer of the dual-phase coolant fluid.

  • Patent number: 12067286
    Abstract: A data storage device includes a memory device and a memory controller. The memory controller uses a first predetermined memory block as a buffer to receive data from a host device. In response to a write command received from the host device, the memory controller determines a sub-region corresponding to the write command, determines whether the sub-region is a system data sub-region and accordingly determines whether to use a second predetermined memory block as another buffer to receive data from the host device. When the memory controller determines that the sub-region corresponding to the write command is a system data sub-region, the memory controller writes the data into the second predetermined memory block. When the memory controller determines that the sub-region corresponding to the write command is not a system data sub-region, the memory controller writes the data into the first predetermined memory block.

A plurality of element packages arranged in matrix on one side of the substrate, the two element packages are connected by the signal lines, and the transparent aperture is surrounded by the signal lines. The signal line is a multi-layer structure for transmitting signal, which can reduce the risk of breaking the signal transmission line during stretching. The transparent aperture is stacked with organic materials, and the inorganic material is removed, which reduces the problem of the cracking and extension of the inorganic material layer when the product is stretched. It also has the effect of reducing the penetration loss caused by the refraction of light through multiple layers, so that the transparent aperture forms a high light-transmitting effect.
