Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air compression apparatuses with adjacently arranged scroll air compressors face inefficiencies in heat removal due to the compact design, which hinders effective cooling of the compressors and after-coolers.
Innovation Solution
The air compression apparatus aligns air compressors in a direction intersecting with the cooling fan's airflow, allowing for efficient cooling by minimizing interference and pressure loss, with separate cooling fans for each compressor and after-cooler to ensure effective heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If air compressors are adjacently arranged to downsize the apparatus, then the dimensional values are reduced, but heat removal efficiency deteriorates
Solution Approach 1:
The patent arranges air compressors in an adjacent configuration along the width direction (second direction) rather than solely in the airflow direction (first direction). This dimensional arrangement allows compressors to be positioned closer together while maintaining cooling efficiency by directing cooling wind from opposite directions, thus reducing apparatus size without compromising heat removal.
Solution Approach 2:
The patent divides the cooling function into multiple independent cooling fans, with each compressor having its own dedicated cooling fan. This segmentation ensures that each compressor receives sufficient cooling wind independently, even when compressors are adjacently arranged, thereby maintaining heat removal efficiency in a compact configuration.
2Volume of moving object
If air compressors are adjacently arranged, then the apparatus is downsized, but cooling wind interference increases
Solution Approach 1:
By arranging compressors along the width direction and providing cooling wind from the longitudinal direction, the patent creates orthogonal cooling pathways that minimize interference between adjacent compressors while maintaining compact dimensions.
Solution Approach 2:
Each compressor is provided with its own dedicated cooling fan that directs cooling wind specifically at that compressor. This localized cooling approach ensures that cooling wind is delivered efficiently to each compressor without being significantly interfered with by adjacent compressors, maintaining ease of cooling operation in a compact arrangement.
3Temperature
If cooling fans are added for each compressor, then cooling efficiency is improved, but device complexity increases
Solution Approach 1:
The cooling fans serve dual functions: they cool the air compressors and also contribute to cooling the after-coolers through their airflow. This multi-functionality allows the system to achieve improved cooling efficiency while limiting the increase in device complexity, as the same cooling fans perform multiple cooling tasks rather than requiring separate dedicated components for each function.
