Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressors in silent vehicles, such as hybrid and fuel cell vehicles, face issues with noise and insufficient cooling of compressed air due to the limited interaction between the discharge port and the intercooler core, leading to inefficient noise reduction and cooling.
Innovation Solution
A compressor design featuring a dispersion wall in the discharge chamber that covers part of the intercooler core and communication hole, ensuring the compressed air flows through the entire intercooler core for enhanced cooling and noise reduction without increasing the compressor size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the discharge port is formed at a position adjacent to the gear housing, then the compressor structure is compact, but the compressed air is not sufficiently cooled because it flows through only a part of the intercooler core
Solution Approach 1:
The discharge chamber is divided into a first discharge chamber and a second discharge chamber by the dispersion wall. This segmentation allows the compressed air to be distributed and flow through different regions of the intercooler core, ensuring complete utilization of the cooling surface area without increasing the overall compressor volume.
Solution Approach 2:
The dispersion wall acts as an intermediary element that redirects and disperses the compressed air flow. It is positioned to cause the air to flow through the entire intercooler core by creating pressure differential and guiding the flow path, thereby improving cooling efficiency without requiring additional space.
2Object-affected harmful factors
If the discharge port is positioned to enable compact structure, then the compressor size is reduced, but the noise development is not sufficiently reduced due to insufficient pressure fluctuation reduction
Solution Approach 1:
By dividing the discharge chamber into two chambers with the dispersion wall, the air flow path is extended and optimized to pass through the entire intercooler core. This segmentation ensures both sufficient cooling and effective noise reduction by maximizing the interaction between the compressed air and the intercooler structure, maintaining compact dimensions.
Solution Approach 2:
The dispersion wall is positioned at a specific location to utilize the three-dimensional space within the discharge chamber effectively. It creates a flow distribution pattern that maximizes the use of available space for both cooling and noise reduction functions without increasing the external dimensions of the compressor.
3Temperature
If the intercooler core area is increased to improve cooling, then the compressed air can be sufficiently cooled, but the compressor size becomes large
Solution Approach 1:
The discharge chamber is segmented by the dispersion wall to create optimized flow paths that maximize the utilization of the intercooler core surface area. This allows the existing intercooler core to be fully utilized for cooling without requiring an increase in its physical dimensions or adding complex cooling structures.
Solution Approach 2:
The dispersion wall dynamically guides and redistributes the compressed air flow to ensure it passes through the entire intercooler core. This dynamic flow management optimizes the cooling efficiency using the existing intercooler core structure, avoiding the need for larger or more complex cooling systems.
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
The dispersion wall ensures effective cooling and noise reduction by dispersing the air flow across the entire intercooler core, reducing pressure fluctuations and pulsation, while maintaining a compact compressor size.
Implementation Method 1
the compressed air is flowed through the intercooler core to be cooled there
Implementation Method 2
The dispersion wall is provided in the discharge chamber on downstream side of the discharge chamber that is opposite from an inflow port with respect to flowing direction of the discharged fluid
Implementation Method 3
the compressed air is flowed through the intercooler core to be cooled there and simultaneously the noise development is lessened by reducing the pressure fluctuation
