Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server cabinets face issues with uneven heat dissipation due to blocked airflow paths and inefficient heat distribution, leading to unstable server operations and potential damage from excessive temperatures.
Innovation Solution
A server cabinet design featuring a rack with opposing frames, a radiator equipped with water supply and drain pipelines, and a fan that creates a steady airflow field by guiding air through the rack, ensuring coolant circulation for effective heat exchange and dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat dissipation fans are mounted at the top of the cabinet to draw hot air outside, then hot air near the top can be exhausted, but airflow paths are blocked by servers and hot air at the bottom accumulates
Solution Approach 1:
The patent transitions from vertical airflow (top-to-bottom) to lateral airflow (front-to-back) by positioning the fan module at the rear side of the cabinet. This dimensional change allows air to flow horizontally through the cabinet, effectively reaching servers at different heights without being blocked by server arrangements, thus resolving the contradiction between top hot air exhaust and bottom hot air accumulation.
2Ease of operation
If the fan module is mounted on the rear side to blow air from rear to front, then bottom hot air accumulation is avoided, but airflow is blocked by heat dissipation fins and connectors resulting in insufficient wind pressure
Solution Approach 1:
The fan module is divided into multiple independent fan units arranged in an array, each capable of generating airflow independently. This segmentation allows the system to maintain high wind pressure while distributing airflow uniformly across multiple paths, preventing blockage effects and ensuring adequate cooling force reaches all server components including those with heat dissipation fins and connectors.
3Loss of energy
If conventional fans exhaust hot air to the outside using thermal convection, then some heat is dissipated, but airflow cannot reach every server or heating element resulting in uneven heat dissipation
Solution Approach 1:
The fan module pre-cools the incoming air from the front side before it enters the cabinet interior. This preliminary cooling action ensures that the air reaching each server and heating element is already at a lower temperature, enhancing the effectiveness of heat dissipation across all components and eliminating the uneven heat dissipation problem that occurs when hot air is merely convected without prior cooling.

AI summary
A server cabinet includes a rack, at least one assembling frame, a radiator and at least one fan. The rack has a first frame and a second frame opposite to each other. The assembling frame and the radiator are mounted on the first frame in sequence. The radiator transfers a coolant to flow inside a plurality of heatsink fins thereof in a circulating manner. The fan is mounted in the assembling frame, and the fan guides an airflow to flow into the first frame from the radiator, and blows the airflow in the rack to the second frame, thus lowering the temperature inside the rack.
