Fluid Cooling Apparatus Integrating Tank Contour with Engine Covering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cooling devices for mobile working machines face spatial and thermal challenges due to limited installation space and the failure of seals under vibrations and shocks, leading to inadequate heat removal and potential re-circulation of heated air.
Innovation Solution
The fluid cooling apparatus integrates the tank's outer wall contour with the engine covering, eliminating the need for internal partitions and incorporating a fan device and heat exchanger unit to enhance heat dissipation while reducing structural weight and noise, with a gasket ensuring no re-circulation of heated air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If partitions are installed to prevent heated air re-circulation, then thermal management is improved, but device complexity increases and reliability decreases due to seal failures under vibrations and shocks
Solution Approach 1:
The tank's outer wall contour is merged with the engine covering, creating an integrated structure where the tank forms part of the vehicle body. This eliminates the need for separate partitions and seals, as the tank itself defines the boundary between cooled and ambient air zones, preventing heated air re-circulation without requiring additional sealing components that could fail under vibration and shock.
2Temperature
If partitions and seals are installed to prevent heated air re-circulation, then thermal management is improved, but structural weight increases
Solution Approach 1:
The tank is integrated into the engine covering structure, with the tank's outer wall forming a component of the vehicle body. This merging eliminates the need for separate partition structures and sealing components, thereby reducing structural weight while maintaining effective thermal management through the tank's own geometric configuration.
3Temperature
If cooling devices are installed inside the covering, then heat removal is improved, but available installation space is reduced
Solution Approach 1:
The cooling system utilizes the external dimension by positioning the tank's heat exchanger units on the outer surface of the vehicle body. The tank's outer wall contour serves as the heat dissipation surface, allowing heat removal to occur in the external thermal field rather than requiring internal installation space within the vehicle covering.
