Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cooling devices for linear motors suffer from pressure loss and dust clogging issues due to continuous holes, leading to inefficient cooling and frequent maintenance needs.
Innovation Solution
A cooling device with a partition plate dividing the cover into upper and lower spaces, where the upper space is used for ventilation and the lower space for cooling, with a slit along the partition plate for communication and a vent at the bottom for efficient air flow, reducing pressure loss and dust accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous holes are provided between cooling portion and ventilation portion, then cooling air can be supplied to the coil, but pressure loss occurs and dust clogging happens
Solution Approach 1:
The partition plate is divided into multiple segments along the longitudinal direction of the duct, with each segment containing multiple holes. This segmentation reduces the total number of holes needed while maintaining effective cooling air distribution, thereby reducing pressure loss while still supplying cooling air to the coil.
Solution Approach 2:
The partition plate acts as an intermediary structure between the ventilation portion and cooling portion. It selectively allows cooling air to pass through its holes while blocking dust particles, serving as a filtering mediator that prevents dust clogging while maintaining cooling efficiency.
2Reliability
If continuous holes are provided between cooling portion and ventilation portion, then cooling air can be supplied to the coil, but dust clogging occurs requiring frequent maintenance
Solution Approach 1:
The partition plate serves as a dust-filtering intermediary that prevents dust particles from entering the cooling portion while allowing cooling air to pass through. This eliminates dust clogging of the holes and the need for frequent cleaning maintenance.
Solution Approach 2:
The dust-filtering function is extracted and integrated into the partition plate structure itself. By combining the partitioning function with the dust-filtering function in one component, the system eliminates the need for separate filters and reduces maintenance requirements.
3Manufacturing precision
If hole diameter is increased with distance from blower, then uniform cooling pressure is achieved, but device complexity increases
Solution Approach 1:
The partition plate is divided into multiple segments along the longitudinal direction, with each segment containing multiple holes. This local distribution of holes provides multiple pathways for cooling air, ensuring uniform pressure distribution along the duct length without requiring complex variable diameter hole designs.
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 ensures homogeneous cooling of the coil with minimal pressure loss and reduced dust clogging, facilitating efficient maintenance by maintaining uniform air pressure and temperature across the coil, thus preventing localized heat buildup.
Implementation Method 1
blower means for forcing a current of cooling air inside the cover
Implementation Method 2
A slit is formed almost along a full length of the partition plate on a side closer to the iron core for bringing the ventilation portion and the cooling portion into communication with each other
Implementation Method 3
the lower space is used as a cooling portion in which the end portions of the coil are accommodate and cooled
