Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibratory apparatuses face challenges in efficiently cooling troughs under high heat loads due to material limitations and inadequate coolant velocity, particularly when transporting molten materials like slag, as they are often made of copper and lack effective cooling mechanisms for increased volumes or different materials.
Innovation Solution
A vibratory apparatus featuring a trough assembly with mild steel plates joined in a catenary shape to create a high-velocity coolant passage, coupled with a vibration generator and a resilient frame, allowing for efficient heat dissipation by passing coolant at high velocity through an unobstructed space between the plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If copper troughs are used for transporting molten materials, then heat dissipation is improved, but material durability and suitability for high heat loads deteriorate
Solution Approach 1:
The trough assembly uses a composite structure combining mild steel plates (for structural strength and heat resistance) with copper or copper-alloy plates (for enhanced heat dissipation). This composite material approach allows the system to simultaneously achieve high durability from the steel and superior thermal conductivity from the copper, resolving the contradiction between material durability and heat dissipation capability.
2Temperature
If coolant velocity is increased to improve cooling efficiency, then heat dissipation is improved, but water hammer effects worsen
Solution Approach 1:
The system dynamically adjusts coolant velocity based on operating conditions. During normal operation, high velocity provides efficient cooling. During shutdown or transient conditions, the system reduces velocity to minimize water hammer effects. This dynamic control allows the system to optimize cooling efficiency while mitigating harmful water hammer effects through real-time velocity modulation.
Solution Approach 2:
The system changes the velocity parameter of the coolant based on operational requirements. By varying the flow velocity within a controlled range, the system achieves high cooling efficiency during peak heat loads while reducing velocity during lower-demand periods to prevent excessive water hammer effects, thus balancing cooling performance with system safety.
3Strength
If troughs are made of steel to improve durability, then material strength is improved, but heat dissipation capability deteriorates
Solution Approach 1:
The trough assembly employs a composite material structure where mild steel plates provide the structural framework and strength, while copper or copper-alloy plates are integrated to provide superior heat dissipation. This composite approach allows the system to simultaneously achieve the high strength required for durability and the high thermal conductivity needed for effective heat dissipation, resolving the contradiction between material strength and heat dissipation capability.
4Temperature
If coolant passage space is increased to improve cooling, then heat dissipation is improved, but device complexity worsens
Solution Approach 1:
The trough assembly is segmented into multiple plates (mild steel plates and copper/copper-alloy plates) arranged in a specific configuration. This segmentation allows the creation of coolant passages between the plates, providing effective cooling surfaces and flow paths without requiring a completely redesigned complex structure. The segmented plate design achieves efficient cooling while maintaining structural simplicity through modular construction.
