Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server systems face reduced heat dissipating efficiency due to reverse airflow directions between graphic processors and main controllers, leading to decreased performance in heat management.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the graphic processor exhausts airflow via the user-facing surface and the main controller exhausts airflow via the opposite surface, then each component can independently dissipate heat, but the reverse airflow fields decrease heat dissipating efficiency
Solution Approach 1:
The patent combines the heat dissipating airflow fields of the graphic processor and main controller into a unified airflow path. The channel diversion device redirects the airflow from the graphic processor to exit through the same surface as the main controller, merging previously opposing airflow fields into a coordinated system that eliminates turbulence and improves overall heat dissipation efficiency.
2Ease of operation
If connection ports are disposed on different surfaces for aesthetic and assembly convenience, then user access and aesthetics are improved, but heat dissipating efficiency decreases due to reverse airflow directions
Solution Approach 1:
The channel diversion device acts as an intermediary airflow control structure that mediates between the conflicting requirements of assembly convenience and heat dissipation efficiency. It allows connection ports to remain on different surfaces for ease of assembly while simultaneously redirecting airflow to ensure both components exhaust heat in the same direction, resolving the conflict between operational convenience and thermal performance.
Applied Scientific Principles

Function Achieved in This Case
The device increases heat dissipating efficiency by aligning airflow directions from electronic components and controllers, preventing reverse airflow conflicts and maintaining high performance in blade and rack servers, including expansion efficiency for circuit boards like PCI-E cards.
Implementation Method 1
The guiding baffle is disposed by a side of the opening on the second structural layer. The collecting mask is disposed by the first structural layer to cover the piercing hole structure. A direction of an outlet of the collecting mask is substantially different from a direction of the opening on the second structural layer.
Implementation Method 2
the electronic component is a heat dissipating component having an active radiator
Implementation Method 3
