Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing charge air cooling systems for internal combustion engines have a complex network of coolant supply and discharge lines, requiring numerous interfaces and branching elements, which complicates assembly, increases installation time, and occupies excessive space.
Innovation Solution
A device with integrated coolant supply and discharge lines within a connecting means, such as a connecting plate or housing wall, that connects multiple heat exchangers, reducing the need for external lines and simplifying assembly by integrating these lines directly into the heat exchanger housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple external coolant supply and discharge lines are used to connect heat exchangers, then the cooling function is achieved, but the device complexity and number of interfaces increase
Solution Approach 1:
The patent merges the coolant supply and discharge lines with the connecting means (housing or connecting plate) by integrating them directly into the structure. The coolant lines are formed as part of the housing or connecting plate, eliminating the need for separate external lines and reducing the number of interfaces required to connect heat exchangers while maintaining the cooling function.
Solution Approach 2:
The connecting means serves multiple functions: it connects the heat exchangers mechanically and simultaneously provides the coolant supply and discharge pathways. This multi-functional design reduces the overall system complexity by combining what would traditionally be separate components into a single integrated structure.
2Adaptability or versatility
If numerous coolant lines and branching elements are used, then the cooling system can serve multiple heat exchangers, but the assembly time and installation complexity increase
Solution Approach 1:
By integrating coolant lines into the connecting means, the patent reduces the number of separate components that need to be assembled. The coolant pathways are pre-formed within the housing or connecting plate, so assembly only requires connecting the heat exchangers to this pre-configured structure, significantly reducing assembly time while maintaining the ability to serve multiple heat exchangers.
3Reliability
If separate coolant lines are used for each heat exchanger, then the cooling function is reliable, but the space occupied by the system increases
Solution Approach 1:
The patent combines the coolant supply and discharge lines with the connecting means structure, allowing multiple coolant pathways to be routed through the housing or connecting plate. This integration enables the system to serve multiple heat exchangers with a compact arrangement, reducing the overall space required compared to separate external lines for each heat exchanger.
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 minimizes the number of coolant lines, reduces assembly time, and optimizes space usage, while also reducing temperature and mechanical stresses between components, leading to a more efficient and streamlined charge air cooling system.
Implementation Method 1
The compressed air heats up and must therefore be cooled down again after compression. This is done using a heat exchanger for charge air cooling.
Implementation Method 2
The charge air is cooled by a coolant, which in turn is cooled by ambient air.
Implementation Method 3
the air sucked in from the environment is charged in one or more stages by means of a compressor of a turbocharger.
