Solution Overview
Problem
Conventional engine cooling systems face challenges in compactness due to the size mismatch between the cooling circuit components and modern vehicle engine compartments, leading to increased thermal stresses as manufacturers strive for more compact and efficient engines.
Innovation Solution
The integration of the pump and conduit within the cylinder block, with an external duct forming a sealed passage zone for the heat transfer fluid, allowing for a compact and adaptable cooling system that can be manufactured using high-pressure casting processes, including aluminum alloys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the pump and conduit are arranged externally on the engine, then the cooling system is easier to manufacture and maintain, but the engine dimensions become too large for modern compact vehicle compartments
Solution Approach 1:
The patent merges the pump and conduit into a single integrated unit that is incorporated into the cylinder block structure. The pump is positioned within the cylinder block, and the conduit is formed as an integral part of the block, eliminating the need for separate external mounting and reducing overall engine volume while maintaining manufacturing feasibility through standardized integration processes
Solution Approach 2:
The pump is nested within the cylinder block structure, with the conduit passing through the block to connect the pump outlet to the cooling circuit inlet. This nesting arrangement allows the cooling system components to be housed within the existing engine structure, significantly reducing the external dimensions required for the cooling system
2Volume of moving object
If the pump and conduit are integrated into the cylinder block, then the engine becomes more compact, but the manufacturing process becomes limited to specific casting methods
Solution Approach 1:
The patent designs the integrated pump and conduit system to be compatible with multiple casting processes including pressure die casting, gravity casting, and investment casting. The structural design of the pump and conduit integration is formulated to work with various aluminum alloys and casting methods, making the solution universally applicable across different manufacturing capabilities and production requirements
