Image Forming Apparatus Cooling via Housing Gap and Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heat dissipation from the information processing section in image forming apparatuses is suppressed due to the lack of a gap between the information processing section and the image forming section and the absence of ventilation holes in the housing's upper surface.
Innovation Solution
Incorporating a gap between the housing and the image forming section and forming ventilation holes in the upper surface of the housing to enhance heat dissipation, with supporting portions to maintain the image forming section's position and using heat sinks and blowing fans for effective cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the image forming section is disposed directly above the information processing section without a gap, then the device structure is more compact, but heat dissipation from the information processing section is suppressed
Solution Approach 1:
The device is divided into distinct sections with a gap between the information processing section and image forming section. This segmentation allows independent thermal management for each section, enabling effective heat dissipation from the information processing section while maintaining overall device compactness.
Solution Approach 2:
Ventilation holes are introduced in the upper surface of the housing to create a three-dimensional heat dissipation pathway. This adds a vertical dimension to heat removal, allowing hot air to escape upward through the ventilation holes while cold air is supplied from the front, creating efficient convection currents without increasing horizontal footprint.
2Temperature
If ventilation holes are formed in the upper surface of the housing, then heat dissipation is accelerated, but the housing structure becomes more complex
Solution Approach 1:
The housing is segmented with strategically positioned ventilation holes that divide the heat dissipation function into distinct entry and exit points. This segmentation of airflow paths simplifies the overall design by creating clear, separate zones for air intake and exhaust, rather than requiring complex integrated cooling systems.
Solution Approach 2:
The ventilation holes in the upper surface serve multiple functions: they act as exhaust openings for hot air, provide structural support for the housing, and contribute to the aesthetic design of the device. This multi-functionality reduces the need for additional separate components, thereby simplifying the overall housing structure.
3Temperature
If a gap is formed between the housing and image forming section, then heat dissipation is improved, but the device occupies more vertical space
Solution Approach 1:
The design utilizes vertical space efficiently by directing heat dissipation through the vertical dimension via upper surface ventilation holes. The gap between sections is minimized while still allowing sufficient airflow, and the ventilation holes provide the necessary thermal relief without requiring excessive vertical clearance, thus optimizing the height-to-cooling-efficiency ratio.
Solution Approach 2:
The gap between the housing and image forming section is optimized locally to provide sufficient space for heat dissipation while minimizing overall vertical height. The ventilation holes are strategically positioned to maximize cooling efficiency in the limited vertical space available, creating localized high-efficiency heat removal zones that do not require uniform increases in overall device height.
