Information Processing Apparatus Bottom Cooling Fan Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information processing apparatuses face inefficiencies in cooling due to the substantial distance between heat generating components and cooling fans, which reduces cooling efficiency, restricts port placement, and increases noise levels.
Innovation Solution
The apparatus redesigns the cooling system by positioning the cooling fan at the bottom surface of the printed circuit board, using a two-stair configuration with a discharging hole and inhaling hole to reduce the distance between the heat generating component and the cooling fan, allowing for improved airflow and miniaturization, while enabling flexible port placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cooling fan is positioned at a side surface or rear surface of the main body, then the structure is simple, but the distance between the cooling fan and heat generating component is substantial, reducing cooling efficiency
Solution Approach 1:
The cooling fan is repositioned from the conventional side/rear surface location to the bottom surface of the main body, utilizing the vertical dimension and bottom surface area. This spatial reconfiguration reduces the horizontal distance between the fan and heat generating components while maintaining structural simplicity, thereby improving cooling efficiency without significantly increasing device complexity.
2Device complexity
If the cooling fan is positioned at a side surface or rear surface of the main body, then the structure is simple, but noises of the cooling fan are directly transmitted to the outside
Solution Approach 1:
The cooling fan is extracted from the conventional side/rear surface position where noise directly transmits to the outside, and relocated to the bottom surface of the main body. This separation removes the noise source from direct contact with external space, effectively reducing noise transmission while maintaining the simplicity of the cooling system structure.
3Adaptability or versatility
If a port is disposed at the space where the cooling fan is positioned in conventional designs, then port placement is flexible, but the cooling fan cannot be properly positioned, reducing cooling efficiency
Solution Approach 1:
The main body surface is segmented into distinct functional zones: the bottom surface accommodates the cooling fan, while the side/rear surfaces are reserved for port placements. This spatial segmentation allows both the cooling fan and ports to be optimally positioned without interference, achieving both cooling efficiency and port placement flexibility.
4Volume of moving object
If the information processing apparatus is miniaturized, then portability is improved, but the distance between heat generating component and cooling fan increases, reducing cooling efficiency
Solution Approach 1:
By utilizing the bottom surface and vertical space of the main body, the cooling fan is positioned in a dimension that allows close proximity to heat generating components even in miniaturized designs. This dimensional approach enables effective cooling in compact apparatus by optimizing the use of available three-dimensional space rather than relying solely on horizontal distance.
