Two-Layer Wind-Guiding Shroud for Server Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heat-dissipating devices with single-axis wind-guiding shrouds have limited airflow convection, leading to insufficient heat dissipation efficiency, requiring multiple fans and shrouds that increase costs and server size, and generate vibrations affecting performance.
Innovation Solution
A two-layer wind-guiding shroud design with staggered wind exits and vertically juxtaposed entrances allows airflow to be directed into different channels, enhancing heat dissipation paths and efficiency while maintaining a simple structure and reducing the number of fans needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single fan with axial wind-guiding shroud is used, then the structure is simple, but the heat dissipation efficiency is insufficient
Solution Approach 1:
The patent transitions from a single-axis (one-dimensional) wind-guiding channel to a two-layer multi-directional channel structure. The first and second wind-guiding channels are arranged in different spatial dimensions, allowing airflow to be directed along multiple axes simultaneously, thereby enhancing heat dissipation efficiency without requiring multiple fans
2Productivity
If multiple fans and wind-guiding shrouds are arranged to enhance heat dissipation, then the heat dissipation efficiency is improved, but the device complexity and server size increase
Solution Approach 1:
The patent merges the functions of multiple wind-guiding shrouds into a single integrated two-layer structure. The first and second wind-guiding channels are combined within one shroud assembly, eliminating the need for multiple separate fans and shrouds while achieving enhanced heat dissipation coverage
3Productivity
If multiple fans are used to improve heat dissipation coverage, then the heat dissipation efficiency is improved, but the vibration affecting hard disk function increases
Solution Approach 1:
The patent segments the wind-guiding function into two distinct channels (first and second wind-guiding channels) within a single fan's airflow path. This allows the single fan to serve multiple heat-generating elements through divided airflow paths, reducing the need for additional fans that would generate more vibration
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The two-layer design increases heat dissipation efficiency, reduces server size and complexity, and minimizes fan-induced vibrations, effectively managing heat from multiple heat-generating elements in high-performance servers.
Implementation Method 1
such a heat dissipation is achieved by air convection in the heat sink together with the heat radiation
Implementation Method 2
The conventional heat-dissipating device (such as a heat sink) is fixed onto a heat-generating element to dissipate the heat generated thereby
Implementation Method 3
such a heat dissipation is achieved by air convection in the heat sink
Implementation Method 4
the amount of heat generated during the operation of the electronic elements increases

AI summary
A two-layer wind-guiding shroud includes a base. The interior of the base includes a first wind-guiding channel and a second wind-guiding channel longitudinally overlapped with each other. The first wind-guiding channel has a first wind entrance and a first wind exit. The second wind-guiding channel has a second wind entrance and a second wind exit. The first wind exit and the second wind exit are staggered. By this arrangement, the airflow generated by a fan can be guided into different wind-guiding channels toward different locations, thereby increasing the heat-dissipating efficiency of the fan.
