Flying Device Cooling System With Low-Mounted Pump
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing flying apparatuses lack an effective cooling system to water-cool the driver (engine) efficiently, especially when the posture tilts during flight, leading to disrupted coolant circulation.
Innovation Solution
A cooling system is implemented with a pump located at the lower portion of the main body assembly, connected via pipes to the driver and radiators, ensuring smooth coolant circulation even during tilts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pump is mounted on the upper portion of the main body assembly, then the pump can be easily installed and accessed, but the coolant circulation is disrupted when the flying apparatus tilts during flight
Solution Approach 1:
The patent inverts the conventional mounting position of the pump by placing it at the lower portion of the main body assembly instead of the upper portion. This inversion resolves the technical contradiction by ensuring that the pump remains at the lowest point regardless of the flying apparatus's tilt angle, maintaining reliable coolant circulation while still being accessible for installation and maintenance.
Solution Approach 2:
The patent applies the equipotentiality principle by positioning the pump at the lower portion of the main body assembly, creating a gravitational equipotential position that ensures the pump is always at the lowest point. This positioning ensures that coolant can consistently flow into the pump inlet regardless of the apparatus's orientation during flight, maintaining circulation reliability.
2Temperature
If a cooling system is added to water-cool the driver, then the driver cooling efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent applies the universality principle by designing the cooling system with a pump that serves multiple functions: it circulates coolant for driver cooling, maintains proper coolant flow direction during tilting, and is positioned to leverage gravitational forces. This multi-functional design achieves effective driver cooling while minimizing additional system complexity.
Solution Approach 2:
The patent merges the cooling system components (pump, cooler, and connecting pipes) into an integrated assembly that works as a unified system. The pump is positioned to naturally align with the cooler and driver, creating a compact configuration that achieves effective cooling without excessive structural complexity.
