Fluid Line Clamp Shielding Plate Heat Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fluid line clamps used alongside hot machine bodies fail to maintain fluid lines due to heat radiation, leading to potential cracking under compression, which results in frequent replacements and operational downtimes.
Innovation Solution
A fluid line clamp design featuring blocks with holes, spaced backing plates, and a shielding plate that reduces heat transfer through air gaps and distributes compression forces, preventing the clamp components from overheating and cracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clamps are used to bind fluid lines alongside hot machine bodies, then the fluid lines are organized and held in place, but the clamps fail to maintain the fluid lines due to heat radiation and may crack under combined heat and compression
Solution Approach 1:
A shielding plate is introduced as an intermediary component between the hot machine body and the clamp assembly. This shielding plate reflects or blocks radiant heat from directly reaching the clamp blocks and fluid lines, thereby protecting the clamp materials from thermal degradation while maintaining their structural integrity and fastening capability
Solution Approach 2:
The clamp system is divided into separate functional components: clamp blocks for holding fluid lines, backing plates for distribution of compression forces, and a shielding plate for thermal protection. This segmentation allows each component to be optimized for its specific function and facilitates maintenance or replacement of individual parts
2Strength
If fasteners are used to compress the clamp components together, then the clamp maintains strong holding force on fluid lines, but the clamp tends to crack under the combined effect of radiating heat and compression of fasteners
Solution Approach 1:
Backing plates are introduced as intermediary elements between the fasteners and the clamp blocks. These backing plates distribute the compressive forces from the fasteners over a larger area, reducing stress concentration points that would otherwise lead to cracking under thermal and mechanical loading
Solution Approach 2:
The clamp system utilizes composite construction with different materials optimized for specific functions: shielding plate material for thermal reflection, clamp block material for mechanical strength and heat resistance, and backing plate material for stress distribution. This composite approach allows the assembly to withstand both thermal radiation and mechanical compression without cracking
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
The clamp effectively reduces heat transfer to the fluid line components, prolongs their service life, and minimizes the risk of cracking, thereby reducing maintenance costs and operational disruptions.
Implementation Method 1
The air gaps between the shielding plate and the blocks reduce heat transfer to the fluid line components

AI summary
A fluid line clamp includes one or more blocks with holes for receiving fluid lines therein. The fluid line clamp further includes a first backing plate, a second backing plate, and a shielding plate. The first and second backing plates are spaced apart from each other to receive the blocks therebetween. The shielding plate is disposed at a distance from the blocks and includes an inner surface, and an outer surface. The inner surface of the shielding plate is rigidly attached to the backing plates. The outer surface of the shielding plate is configured to rigidly attach to a hot body of a machine.
