  • Publication number: 20240179873
    Abstract: A system with a circuit with components, an enclosure with a top and a bottom, and a heat transfer device. The heat transfer device has an exterior surface with a first portion, a second portion, and a third portion, where the first portion faces opposite the second portion; and an interior surface with a fourth portion, a fifth portion, and a sixth portion, where the fourth portion faces the fifth portion. The first portion configured to thermally couple to the top of the enclosure. The second portion configured to thermally couple to the bottom of the enclosure. The fourth portion configured to couple to a component mounted on a primary side of the circuit board. The fifth portion configured to face a secondary side of the circuit board. The first heat transfer device configured to distribute thermal energy generated from a component to the top and bottom of the enclosure.

  • Publication number: 20240172398
    Abstract: Aspects of the present disclosure configure a memory sub-system processor to use a triangular shaped metal bracket to improve heat dissipation to improve a data transfer rate. The triangular shaped metal bracket being physically attached to an edge of the PCB at a base portion of the triangular shaped metal bracket. The triangular shaped metal bracket is thermally coupled to the set of memory components and the processing device of the PCB via the base portion along with a heat spreader on a primary and secondary side of the bracket. The triangular shaped metal bracket being configured to dissipate heat from the processing device and the set of memory components to at least a host device through a vertex portion of the triangular shaped metal bracket.

  • Publication number: 20240114660
    Abstract: Example embodiments are directed to a solid-state drive (SSD) enclosure design that is adaptable for different printed circuit board assemblies (PCBA). The SSD enclosure design comprises a three-piece construction that includes a top enclosure, a bottom enclosure, and an intermediate structure. The bottom enclosure is coupled to the top enclosure to form a housing for a PCBA having NOT AND (NAND) devices and a controller. The intermediate structure is coupled to the PCBA and positioned between the top enclosure and the bottom enclosure within the housing. The intermediate structure comprises a plurality of heatsinks to transfer heat from the NAND devices and a controller heatsink to transfer heat from the controller, whereby the type and location of the heatsinks can be changed for a different PCBA without having to change the top enclosure or bottom enclosure. The top enclosure can include vents that allow air to flow through.

  • Publication number: 20240107657
    Abstract: Aspects of the present disclosure are directed to a memory sub-system with isothermal cooling of components. A PCB assembly may be secured between a heat spreader and a heat sink that are thermally coupled. The heat sink radiates heat absorbed from both sides of the PCB assembly. By connecting the heat spreader to the heat sink, heat is more effectively transferred from the side of the PCB assembly not directly connected to the heat sink. The PCB assembly may be secured between a top enclosure and a bottom enclosure. The top enclosure and the bottom enclosure may be thermally coupled using a vapor chamber. The vapor chamber pumps heat from a higher-temperature side of the PCB assembly to a lower-temperature side of the PCB assembly. By using the vapor chamber to thermally couple the top and bottom enclosures, creation of hot spots is avoided.

  • Publication number: 20240069581
    Abstract: Some memory sub-systems are operated in high temperature and low airflow environments. As a safeguard, thermal throttling may limit throughput on a memory sub-system when a predetermined temperature is reached or exceeded. Improving heat dissipation increases the amount of time a memory sub-system can operate without initiating thermal throttling. Adding a phase-change material (PCM) with a melting temperature above the ambient temperature but below the thermal throttling temperature to a memory sub-system increases the amount of heat the memory sub-system can generate before the temperature reaches the thermal throttling temperature. Thermally coupling components with a heat spreading sheet causes the temperature of the components to vary less than when the components transfer heat by air. Thus, a component that generates less heat may be used to absorb heat generated by another component, increasing the amount of time before any component reaches the thermal throttling temperature.

  • Publication number: 20230397372
    Abstract: An apparatus including a heat sink having two or more sections of parallel fins that define colinear channels is disclosed herein. The colinear channels are configured to direct flow of air or coolant across the heat sink and have wider channel widths closer to an inlet for the air or coolant and narrower widths closer to an outlet for the air or coolant.
