Pivoting Fan Wall for Server Rack Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server rack systems have limited heat-dissipating efficiency due to the restricted dimensions of fans, requiring more fans to be used, which increases equipment costs and complexity.
Innovation Solution
A server rack system with a pivoting heat-dissipating wall that allows for the use of large-sized fans, integrated with a water-cooling mechanism and a power transmission module, enabling efficient heat dissipation and reduced equipment costs by minimizing the number of fans needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If small-sized fans are used due to rack space restrictions, then the rack structure is maintained, but heat-dissipating efficiency deteriorates
Solution Approach 1:
The patent extracts the fan assembly from the traditional rack structure by introducing a separate heat-dissipating wall that can be pivoted into position. This allows large-sized fans to be used without being constrained by the rack's internal space limitations, as the fans are mounted on the movable wall rather than being integrated into the rack framework.
Solution Approach 2:
The heat-dissipating wall is designed to be movable (pivoted) rather than fixed, allowing the system to dynamically adjust between two states: with the wall folded against the rack for compact storage, and with the wall unfolded to provide full fan functionality for effective heat dissipation. This dynamic structure resolves the contradiction between space constraints and fan size requirements.
2Temperature
If multiple small fans are configured to achieve acceptable heat dissipation, then heat-dissipating efficiency is improved, but equipment costs increase
Solution Approach 1:
The patent merges multiple fan functions into a single large-sized fan by providing an expanded mounting surface on the heat-dissipating wall. This consolidation reduces the total number of fans required while maintaining or improving heat-dissipating efficiency, thereby lowering equipment costs.
3Temperature
If the heat-dissipating wall is unfolded to accommodate large fans, then heat-dissipating efficiency is improved, but the rack occupies more space
Solution Approach 1:
The heat-dissipating wall is designed to be movable (pivoted) rather than fixed, allowing the system to dynamically adjust between two states: with the wall folded against the rack for compact storage, and with the wall unfolded to provide full fan functionality for effective heat dissipation. This dynamic structure resolves the contradiction between space constraints and fan size requirements.
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 system achieves improved heat-dissipating efficiency using large-sized fans and a water-cooling mechanism, reducing the number of fans required and lowering equipment costs while facilitating easier installation and maintenance.
Implementation Method 1
The fans are adapted for sucking cool air, such that the cool air enters the rack from the front end and passes through the servers. Heat exchange between the cool air and the servers is carried out to generate hot air. The hot air flows out of the rack through the heat-dissipating wall, so as to dissipate heat of the servers.
Implementation Method 2
the heat-dissipating wall further includes a water-cooling wall that covers the fan wall. After the hot air generated by the heat exchange between the cool air and the servers flows through the water-cooling wall, the hot air becomes cool air that flows out of the rack.

AI summary
A server rack system includes a rack, servers, and a heat-dissipating wall. The rack has guiding rails, a front end, and a rear end opposite to the front end. The servers slidably configured on the guiding rails and in the rack are adapted for being moved into or out of the rack from the front end. The heat-dissipating wall is pivoted to the rear end and adapted for being folded against or unfolded away from the rear end. The heat-dissipating wall includes a fan wall. Fans lie on the fan wall. The fans are adapted for sucking cool air, such that the cool air enters the rack from the front end and passes through the servers. Heat exchange between the cool air and the servers is carried out to generate hot air that flows out of the rack through the heat-dissipating wall to dissipate heat of the servers.
