Vehicle cooling system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle cooling systems are hindered by the weight-transmitting connection between the blower device and housing, leading to increased dead weight and a suboptimal fluidic design due to the need for thick walls and additional struts, which compromises mechanical resistance and airflow efficiency.
Innovation Solution
A support device is designed to transmit the weight of the blower device exclusively to the cooling air-coolant liquid heat exchanger, allowing for reduced wall thicknesses and material usage, while maintaining mechanical resistance, and enabling a fluidically optimized fan housing design by separating the weight transmission from the blower housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the blower unit is connected to the blower housing in a weight-transmitting manner, then mechanical resistance is ensured, but the weight of the vehicle cooling system increases and fluidic design is compromised
Solution Approach 1:
The support structure is divided into two functional parts: a carrier device that provides mechanical support and weight transmission, and a blower housing that provides fluidic guidance. This segmentation allows each component to be optimized for its specific function without compromise.
Solution Approach 2:
The weight-transmitting function is extracted from the blower housing and transferred to a separate carrier device. This extraction allows the blower housing to be designed purely for fluidic purposes without the constraint of supporting the blower unit's weight.
2Stability of the object's composition
If the blower unit is connected to the blower housing in a weight-transmitting manner, then mechanical stability is ensured, but the design of the blower housing is compromised between mechanical strength and fluidic design
Solution Approach 1:
The system is segmented into a carrier device for mechanical stability and a blower housing for fluidic design. The carrier device handles all weight-bearing functions while the blower housing focuses exclusively on optimizing air flow paths.
Solution Approach 2:
The mechanical support function is extracted from the blower housing design, allowing the housing to be freely shaped for optimal fluidic performance without being constrained by mechanical strength requirements.
3Strength
If additional bracing is added to create a weight-transmitting connection, then mechanical resistance is improved, but device complexity and weight increase
Solution Approach 1:
The carrier device merges multiple functions into a single component: it provides structural support, transmits weight, and positions the blower unit. This consolidation eliminates the need for separate bracing elements while maintaining mechanical integrity.
Solution Approach 2:
The carrier device is designed as a multi-functional component that simultaneously performs mechanical support, weight transmission, and spatial positioning functions, replacing what would otherwise require multiple separate structural elements.
