Server Heat Dissipation Channel Structure for Uniform Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server cooling systems using fans to dissipate heat from multiple sources within a server result in uneven cooling effects due to varying distances from the fan, leading to temperature differences among heat-generating components and potential operational issues.
Innovation Solution
A server heat dissipation channel structure comprising upper and lower guiding shields and a fan, where the upper guiding shield has an entrance section and a flow guiding channel, and the lower guiding shield has a first heat dissipation channel, with a downward slanted channel converging to form a second heat dissipation channel, ensuring uniform airflow distribution across heat-generating sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a fan is used to draw external air into the server for cooling, then the cooling function is provided, but the cooling effect is uneven among heat generating sources at different distances from the fan
Solution Approach 1:
The cooling system is segmented into multiple independent cooling channels (first cooling channel, second cooling channel, third cooling channel) that separately direct air to different heat generating sources. This segmentation ensures that each heat generating source receives dedicated cooling airflow, eliminating the uneven cooling effect caused by distance variations from a single fan.
Solution Approach 2:
Guiding shields are introduced as intermediary components to redirect and distribute airflow from the fan to different regions of the server. The guiding shields act as mediators that split the single airflow source into multiple directed streams, ensuring uniform cooling distribution across all heat generating sources regardless of their positions.
2Adaptability or versatility
If heat generating sources are installed at different distances from the fan, then more components can be accommodated, but temperature differences arise among the components
Solution Approach 1:
Different cooling channels are designed with locally optimized paths and shielding structures tailored to the specific thermal requirements and positions of different heat generating sources. Each cooling channel is configured to deliver adequate airflow to its designated target, ensuring that components at various distances and positions all receive appropriate cooling to maintain reliable operation.
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
This configuration provides a uniform cooling effect for all heat-generating sources within the server, preventing temperature differences and ensuring normal server operation by directing external air directly to each source, regardless of its distance from the fan.
Implementation Method 1
the fan includes an air output plane facing toward the upper entrance section and the lower guiding shield correspondingly
Implementation Method 2
a first heat dissipation channel extended from the lower entrance section... the first and second heat dissipating channels respectively pass through different portions of the heat generating sources

AI summary
A server heat dissipation channel structure, used in a server having a plurality of heat generating sources installed therein, includes an upper guiding shield, a lower guiding shield and a fan. The upper guiding shield includes an upper entrance section and a flow guiding channel extended therefrom. The lower guiding shield includes a lower entrance section and a first heat dissipation channel extended therefrom. The fan includes an air output plane facing toward the upper entrance section and the lower entrance section correspondingly at the same time. In addition, the upper guiding shield includes a downward slanted channel at a rear end of the flow guiding channel opposite from a rear end of the first heat dissipation channel and a second heat dissipation channel extended from the first heat dissipation channel. The first and second heat dissipating channels respectively pass through different heat generating sources installed inside the server.
