An enhanced IO bracket is introduced that offloads heat from the controller to the IO bracket, using heat pipes and fins to distribute heat away from the main heatsink, improving thermal management and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional heatsink designs are used for PCIe SSDs, then the design is simple and compliant with ASHRAE A2 standard, but the thermal limits cannot be met under ASHRAE A3 standard and overheating occurs
Solution Approach 1:
The patent divides the heat dissipation system into two separate functional components: a top heatsink dedicated to NAND devices and an IO bracket with heat pipes dedicated to the controller. This segmentation allows each component to be optimized for its specific thermal load, enabling compliance with ASHRAE A3 standards while maintaining manageable complexity through modular design.
Solution Approach 2:
The IO bracket acts as an intermediary heat transfer component between the controller and the external environment. It incorporates heat pipes that transfer heat from the controller to the IO bracket structure, which then dissipates heat to the ambient air. This intermediary mechanism enables effective thermal management without requiring complete redesign of the entire heatsink system.
2Temperature
If the controller heat is transferred to the main heatsink, then the heatsink design is simple, but the heat load on the main heatsink increases and thermal limits are exceeded
Solution Approach 1:
The patent segments the thermal management function by creating separate heat dissipation paths: one for NAND devices through the top heatsink and another for the controller through the IO bracket with integrated heat pipes. This prevents heat load concentration on the main heatsink and enables compliance with ASHRAE A3 thermal standards.
Solution Approach 2:
The patent extracts the controller heat transfer function from the main heatsink system and relocates it to the IO bracket. By removing the controller thermal load from the NAND device heatsink, the system can maintain lower temperatures for the NAND devices while still dissipating controller heat effectively through the dedicated IO bracket pathway.
3Temperature
If heat pipes are added to the IO bracket for heat transfer, then thermal performance improves and ASHRAE A3 compliance is achieved, but the device complexity increases
Solution Approach 1:
The patent merges the IO bracket structural component with the heat dissipation function by integrating heat pipes directly into the bracket. This combination allows the IO bracket to serve dual purposes: providing mechanical support for the controller and simultaneously acting as a heat transfer pathway. The merging reduces the need for separate heat dissipation components and enables ASHRAE A3 compliance through an integrated design.

AI summary
Example embodiments are directed to an input/output (IO) bracket that may be used in a solid-state drive (SSD), the IO bracket comprises a faceplate and at least one heat pipe coupled to the faceplate that extends horizontally from a surface of the faceplate. The at least one heat pipe is configured to be coupled to a controller of the SSD in order to transfer heat from the controller out of the SSD. By coupling the controller to the heat pipe instead of a main heatsink, the main heatsink can efficiently dissipate heat from remaining components of the SSD.
