Dual-Fan Air Compressor Cooling in Compact Vehicle Layouts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Piston type air compressors used in vehicles suffer from inadequate heat dissipation due to their compact internal configuration and narrow space, leading to inefficient cooling airflow.
Innovation Solution
The air compressor incorporates a second cooling fan that is not coaxial with the motor, in addition to a first cooling fan coaxial with the motor, to generate heat dissipation airflow at different positions, along with a gear set where the second and third gears are pivotally connected to the same frame, simplifying installation and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a single cooling fan coaxial with the motor is used, then the structure is simple, but the heat dissipation efficiency is insufficient due to poor cooling airflow in the compact space
Solution Approach 1:
The cooling fan is divided into two separate fans: a first cooling fan coaxial with the motor and a second cooling fan not coaxial with the motor. Each fan is positioned to generate cooling airflow at different locations within the air compressor, thereby improving overall heat dissipation efficiency while maintaining a relatively simple structure
Solution Approach 2:
The cooling airflow is extended from a single axial direction (coaxial with motor) to multiple directions by adding the second cooling fan at a different position. This creates multi-dimensional cooling airflow that covers more heat-generating components within the compact space
2Volume of moving object
If the internal configuration is made compact to reduce size, then the air compressor fits better in vehicles, but the cooling airflow efficiency deteriorates
Solution Approach 1:
Different regions within the air compressor are provided with targeted cooling airflow from the first and second cooling fans. The first cooling fan addresses cooling needs near the motor, while the second cooling fan addresses cooling needs in other heat-generating regions, ensuring effective heat dissipation throughout the compact device
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 enhances heat dissipation efficiency and reduces manufacturing and assembly costs by allowing airflow to be generated at multiple positions within the air compressor.
Implementation Method 1
The motor is adapted to drive the first cooling fan to rotate, and is adapted to drive the second cooling fan to rotate by the gear set. The first cooling fan and the second cooling fan can be used to generate heat dissipation airflow at different positions in the air compressor.
