Machine Tool Cooling Air Inlet Offset Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Machine tool apparatuses face inefficiencies in cooling and dust extraction due to the lack of a coherent fluid flow system that can effectively utilize air for both cooling and extraction functions, particularly in brushless motors and battery-powered devices.
Innovation Solution
The integration of a connection unit that fluidly connects the cooling air inlet section to a fluid unit outside the housing, allowing for conditioned air to be used for both cooling and extraction, with a filter element and dust collection container to manage ablation and provide efficient air flow, and the use of fan units to generate airflow for extraction and cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate cooling and extraction systems are used, then each function can be optimized independently, but device complexity increases and space is wasted
Solution Approach 1:
The patent combines the cooling air inlet section and extraction air inlet section into a single common air inlet that draws ambient air. This merging of previously separate air intake systems reduces the number of components, simplifies the overall structure, and eliminates redundant space while maintaining both cooling and extraction functions through a shared airflow path
2Device complexity
If a coherent fluid flow system is implemented for both cooling and extraction, then space is saved and structure is simplified, but the air flow must be effectively conditioned for multiple functions
Solution Approach 1:
The patent implements a universal air flow system where a single conditioned air stream serves multiple functions: it cools the brushless motor through the cooling air outlet and simultaneously provides extraction through the extraction air outlet. The fluid connection enables this multi-functionality by distributing the conditioned air to different outlets that serve different purposes within the housing
3Use of energy by moving object
If ambient air is used for both cooling and extraction, then no additional air conditioning is needed, but the air must be properly directed to serve both functions effectively
Solution Approach 1:
The system utilizes ambient air directly without requiring additional air conditioning equipment. The housing structure itself, with its strategically positioned cooling air outlet section and extraction air outlet section, automatically directs the air flow to perform both cooling and extraction functions. The fluid connection between inlet sections and outlet sections creates self-directed airflow paths that eliminate the need for complex control mechanisms
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 solution enables a particularly efficient and gentle cooling of the machine tool's interior while effectively extracting ablation, reducing contamination and damage, and enhancing the overall performance of the machine tool apparatus.
Implementation Method 1
The machine tool apparatus has a fan unit for generating an air flow between the fluid unit and an interior of the housing unit
Implementation Method 2
an air flow provided for the cooling air inlet section can advantageously also be used for the fluid unit. Advantageously, an air conducted via the fluid unit can be conditioned by means of the fluid unit before the cooling air inlet section

AI summary
A machine tool apparatus includes at least one housing unit, which has a cooling air inlet section and a cooling air outlet section. The cooling air outlet section is arranged offset from the cooling air inlet section as viewed in the direction of a main extension axis of the housing unit. The machine tool apparatus further includes a connecting unit for fluidly connecting the cooling air inlet section with a fluid unit on the outside of the housing unit.
