Solution Overview
Problem
In data center cabinets, vacant slots allow airflow to overflow, reducing the air intake volume and impairing the heat dissipation of line cards.
Innovation Solution
An air deflection plug-in unit with a housing and a flow guiding structure is introduced, featuring angled air intake and exhaust vents that guide airflow to improve heat dissipation without blocking airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air baffles are inserted into vacant slots to block airflows, then airflow bypasses are reduced and heat dissipation for line cards is improved, but total air intake volume decreases affecting overall heat dissipation effect
Solution Approach 1:
The air deflection plug-in unit serves as an intermediary component inserted into vacant slots. It includes a flow guiding structure with air intake vents and air exhaust vents that mediates airflow by guiding it from the air intake vents through the flow guiding structure to the air exhaust vents, directing airflow toward slots containing line cards while maintaining total air intake volume
Solution Approach 2:
The vacant slot is segmented into multiple functional regions: air intake vents for receiving airflow, flow guiding structure for directing airflow, and air exhaust vents for releasing guided airflow. This segmentation allows the vacant slot to actively participate in heat dissipation rather than merely providing bypasses
2Temperature
If air baffles are used to block airflow in vacant slots, then airflow direction is controlled to improve local heat dissipation, but device complexity increases
Solution Approach 1:
The air deflection plug-in unit is designed as a universal component that can be installed in any vacant slot regardless of position. Each unit performs multiple functions: blocking bypasses, guiding airflow, and maintaining air intake volume. This multi-functionality reduces the need for different types of components for different slots, simplifying overall system complexity
Solution Approach 2:
The flow guiding structure utilizes parameter changes in airflow direction and path. By designing air intake vents and air exhaust vents at specific positions and angles, the structure naturally guides airflow through geometric parameters rather than requiring complex mechanical control mechanisms
