Radiator Basket Suction Arms for Sealed Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiator baskets with cleaning devices face challenges in sealing and maintaining air flow efficiency due to relative movement between rotating parts, leading to increased pressure drop and reduced cooling performance, especially in high contamination environments like grain harvesting.
Innovation Solution
A radiator basket with a cleaning device featuring two pivotally mounted suction arms with diagonal bearing points, which eliminates relative movement and wear, ensuring a sealed and efficient air flow by using a crank mechanism and drive coupling for synchronized movement, and a cuboid design for increased air intake.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rotating radiator basket with a fixed suction nozzle is used, then the cleaning device can remove particles from the surface, but the pressure drop increases significantly and fan power requirements increase
Solution Approach 1:
The patent makes the suction nozzle movable by mounting it on the rotating radiator basket itself, allowing the nozzle to rotate together with the basket. This dynamic configuration enables the suction opening to continuously face the direction of particle deposition without requiring the entire basket to rotate, thereby reducing the active grid area and associated pressure drop while maintaining effective particle removal.
2Reliability
If a rotating radiator basket is used, then cleaning can be achieved, but a seal is required between the rotating basket and stationary radiator box
Solution Approach 1:
Instead of rotating the entire radiator basket and requiring a seal between rotating and stationary parts, the patent inverts the approach by keeping the radiator basket stationary and rotating only the suction nozzle assembly. This eliminates the need for complex sealing mechanisms between rotating and stationary components, as the rotation now occurs within the stationary basket structure where sealing is simplified.
3Productivity
If the suction area is increased to handle more air flow, then cooling performance improves, but the pressure drop and required fan power increase
Solution Approach 1:
The patent applies local quality by concentrating the suction function at the specific location where particles are deposited on the radiator surface, rather than increasing the overall suction area. The suction nozzle is positioned and oriented to target the contamination zone locally, maintaining effective particle removal without requiring a large suction area that would increase pressure drop and energy consumption.
