Armored Vehicle Cooling Air Inlet Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing engine cooling systems for armored vehicles require powerful and expensive fans to overcome the resistance of ballistic gratings, leading to increased weight and cost, while still needing to maintain adequate cooling and protection.
Innovation Solution
The cooling air inlets are integrated above the vehicle's trough roof, between additional protective plates, eliminating the need for gratings, and the cooling air outlets are protected without ballistic protection, using a simpler fan setup with a coolant cooler integrated in the airflow, and additional protection is provided within the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ballistic gratings are used in cooling air intake and exhaust areas, then ballistic protection is improved, but fan power requirements and flow resistance increase significantly
Solution Approach 1:
The invention extracts the ballistic protection function from the cooling air intake path by positioning the cooling air inlet above the tub roof in the space between raised protective plates, eliminating the need for ballistic gratings in the cooling airflow path while maintaining protection through the collar structure
Solution Approach 2:
The circumferential collar acts as an intermediary structure that provides ballistic protection for the vehicle and cooling air inlet simultaneously, mediating between the protective plates and the cooling system to eliminate the need for additional gratings
2Reliability
If ballistic gratings are used in cooling air intake and exhaust areas, then ballistic protection is improved, but system weight and cost increase
Solution Approach 1:
The invention removes the ballistic grating components from the cooling air intake and exhaust areas, extracting the protection function to the collar structure instead, thereby reducing system weight while maintaining adequate protection
Solution Approach 2:
The circumferential collar serves multiple functions: it provides ballistic protection for the vehicle, covers and protects the cooling air inlet, and eliminates the need for separate grating structures, achieving multi-functionality that reduces overall system weight
3Reliability
If ballistic gratings are used in cooling air intake and exhaust areas, then ballistic protection is improved, but device complexity and expense increase
Solution Approach 1:
The invention extracts the ballistic protection requirement from the cooling air intake path by positioning the inlet above the tub roof between protective plates, eliminating complex grating structures and associated mounting systems
Solution Approach 2:
The circumferential collar provides multiple functions including ballistic protection, cooling air inlet coverage, and structural support, eliminating the need for separate grating components and reducing overall device complexity
4Power
If cooling air inlet is positioned above tub roof between protective plates, then fan power requirements are reduced, but protection coverage must be maintained
Solution Approach 1:
The circumferential collar acts as an intermediary that provides ballistic protection while allowing the cooling air inlet to be positioned in the optimized location above the tub roof, mediating between protection requirements and cooling performance
Solution Approach 2:
The collar structure provides both ballistic protection and serves as the cover for the cooling air inlet, achieving multi-functionality that simultaneously satisfies protection requirements and enables optimized cooling air intake positioning
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration achieves optimal protection with minimal weight and low costs, maximizing cooling capacity while minimizing drive power and flow resistance, reducing the need for powerful fans and gratings.
Implementation Method 1
a coolant cooler (11, 12) which is integrated into the cooling airflow
Implementation Method 2
A simple axial or radial fan with sufficient intake capacity can be used. This fan pushes the cooled air out of at least one cooling air outlet
