Roof Dryer Nozzle Flow Deflection for Perpendicular Vehicle Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roof drying devices for vehicles do not achieve optimal drying results due to limitations in airflow direction and distribution, which can lead to incomplete drying of vehicle surfaces.
Innovation Solution
The integration of a flow deflection element within the nozzle body of the drying device, which deflects drying air in a specific arcuate manner to ensure it exits perpendicularly from the outlet opening, combined with a rotatable nozzle design and adjustable air guiding elements, allows for targeted and efficient airflow distribution across the vehicle surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If drying air is blown out in the direction of the vehicle to blow off cleaning liquid, then the vehicle surface can be dried, but the airflow does not achieve optimal drying results due to limitations in airflow direction and distribution
Solution Approach 1:
The flow deflection element is designed with an arcuate shape that deflects the drying air flow in a curved path. The arcuate geometry redirects the air flow from the blower device to exit perpendicular to the vehicle surface, optimizing the drying effect by ensuring uniform airflow distribution across the surface being dried.
2Speed
If the outlet opening is slot-shaped to achieve high flow velocity and create a directed flow curtain, then flow velocity is improved, but the airflow may not adapt optimally to different vehicle contours
Solution Approach 1:
The nozzle body is designed to be rotatable about an axis, allowing the slot-shaped outlet opening to change its orientation and direction. This dynamic adjustment capability enables the high-velocity airflow curtain to adapt to different vehicle contours and surfaces, maintaining optimal drying performance across various geometries while preserving the benefits of the slot-shaped design for velocity generation.

Implementation Method 1
the at least one nozzle body comprises or forms a flow deflection element upstream of the outlet opening in the inflow direction of the drying air flowing in from the at least one blower device, via which the drying air is transferred to the side of the flow channel facing the outlet opening
Implementation Method 2
at least one blower device for providing drying air
Implementation Method 3
the flow deflection element, in particular a wall of the at least one nozzle body, extends in an arc shape on a side facing the outlet opening away from the plane of the outlet opening and then in the direction of the outlet opening
