Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In server housings, the installation of heat-dissipating fans often reduces the space available for mounting hard disks due to limited internal space, necessitating an improvement in heat-dissipating efficiency without compromising the arrangement of electronic devices.
Innovation Solution
A heat-dissipating assembly featuring first and second heat-dissipating holes inside the housing, positioned to enhance air convection, allowing the fan to be placed within the power supply without obstructing other electronic devices, utilizing a fan located inside the power supply and heat-dissipating holes on the partitioning plate and casing to facilitate airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat-dissipating fan is mounted on the housing to improve heat dissipation, then heat-dissipating efficiency is improved, but the space available for mounting hard disks is reduced
Solution Approach 1:
The heat-dissipating fan is extracted from the housing and relocated to the power supply unit. This separation allows the fan to be positioned within the power supply's casing rather than mounting it directly on the housing, thereby preserving the housing's internal space for hard disk installation while maintaining heat dissipation functionality
Solution Approach 2:
The fan is nested within the power supply casing, which itself is installed in the housing. This nested arrangement allows the fan to be housed inside an existing component's boundary, utilizing otherwise wasted space within the power supply unit and avoiding additional space consumption in the main housing
2Temperature
If another fan is mounted on one side of the housing to generate compulsive airflow, then heat-dissipating efficiency is improved, but the arrangement of electronic devices is affected
Solution Approach 1:
The second fan is extracted from the housing structure and relocated to the power supply unit. This extraction eliminates the need to mount fans on the housing's external surfaces, thereby preserving the housing's adaptability for various electronic device arrangements while maintaining the compulsive airflow function for heat dissipation
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 improves heat-dissipating efficiency and maintains space for electronic devices by creating effective air channels for heat dissipation without reducing the space for hard disk mounting, thereby enhancing the practicality of the heat-dissipating assembly.
Implementation Method 1
The airflow generated by the fan drives the air in the housing to flow out of the housing via the first heat-dissipating holes and the second heat-dissipating holes

AI summary
A heat-dissipating assembly for a server includes a housing in which a partitioning plate and a power supply mounted on one side of the partitioning plate are provided. The power supply includes a casing and a power-supplying module received in the casing. The heat-dissipating assembly includes a fan received in the casing and located outside the power-supplying module. The partitioning plate and the casing are respectively provided with a plurality of first heat-dissipating holes and second heat-dissipating holes. The first heat-dissipating holes and the second heat-dissipating holes are positioned to correspond to the fan. The airflow caused by the fan drives the air inside the housing to flow out of the housing via the first heat-dissipating holes and the second heat-dissipating holes. In this way, the heat-dissipating efficiency can be improved without affecting the arrangement of other electronic devices in the housing.
