Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current heat transfer apparatuses for high-pressure and high-temperature applications are inefficient due to thick walls needed for pressure resistance, leading to high material costs, large dimensions, and difficulty in assembly, while also being prone to deformation and corrosion, especially when handling viscous substances.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If thick-walled pipes are used to withstand high pressures, then pressure resistance is improved, but heat transfer capacity deteriorates due to low thermal conductivity of metallic materials
Solution Approach 1:
The apparatus divides the pressure-bearing function from the heat transfer function by using a modular plate structure with multiple channels, where thin walls perform heat transfer while the overall structure withstands pressure
Solution Approach 2:
The patent employs thin-walled plate structures instead of thick pipes, utilizing the high surface-area-to-volume ratio of thin walls to maximize heat transfer efficiency while maintaining structural integrity through the overall apparatus design
2Reliability
If corrosion-resistant materials with low strength values at high temperatures are used, then corrosion resistance is improved, but structural strength deteriorates, requiring enveloping jacket pipes that increase material usage and reduce heat transfer performance
Solution Approach 1:
The apparatus uses multiple separate plate channels instead of single thick-walled pipes, allowing corrosion-resistant materials to be used in thin-walled configurations where each plate handles specific fluid streams independently
Solution Approach 2:
The patent employs composite construction with multiple plate layers and sealing elements, combining materials with different properties to achieve both corrosion resistance and structural strength without requiring thick single-layer walls
3Productivity
If parallel arrangements of thick-walled single-layer or multi-layer pipes are used to generate high throughputs, then productivity is improved, but apparatus dimensions and weight increase, making the apparatus large and expensive
Solution Approach 1:
The patent merges multiple heat transfer channels into a compact plate assembly where plates are stacked and sealed together, achieving high throughput through parallel flow paths while maintaining a compact, lightweight structure compared to parallel pipe arrangements
Solution Approach 2:
The apparatus transitions from one-dimensional pipe arrangements to a multi-dimensional plate stack configuration, utilizing vertical stacking and lateral sealing to create efficient heat transfer pathways in multiple directions within a compact footprint
4Loss of energy
If extremely thin metal sheets are used in plate heat exchangers, then heat transfer efficiency is improved, but deformation risk at high pressures increases and corrosion resistance deteriorates
Solution Approach 1:
The plate structure is divided into multiple rigidly connected plates that collectively withstand pressure, allowing individual thin plates to maintain high heat transfer efficiency while the assembled structure provides deformation resistance
Solution Approach 2:
The patent applies different local qualities by using thin walls in heat transfer areas while providing structural reinforcement at critical locations through the plate assembly configuration and sealing mechanisms

Function Achieved in This Case
The apparatus achieves efficient heat transfer, reduces material costs, and facilitates easy cleaning, while maintaining structural integrity under high pressures and temperatures, with the ability to handle viscous substances and corrosive fluids.
Implementation Method 1
each structured layer has at least one resilient and deformable spring web (202,302) running parallel to the side wall (4,5) or to the face plate in its longitudinal extent
Implementation Method 2
the spring bar is connected to at least one connecting bar (203,303) to the parallel guide bar (204,304) in the layer plane, and starting from the guide bar and/or spring bar, a large number of shorter intermediate bars (205,305) run to the opposite parallel spring bar
Implementation Method 3
intermediate bars in a straight extension one have a spring gap (206,306) with a deformation path (207,307) and limit a deformation of the spring bar
Implementation Method 4
in the inflow and outflow zone of the fluids a large number of support bars (208,308) of different lengths protrude into the flow area, bars one-sided surface contact width wall or to the width plate and have one-sided surface contact with adjacent webs of adjacent layers in order to conduct existing compressive forces into the surrounding outer housing
Implementation Method 5
connecting, intermediate and supporting webs of layers of the inserts and attachments have an angle of inclination a of 10 to 70 degrees to the respective main flow direction, and one of the two layers of inserts and attachments is rotated 180 degrees around its own longitudinal axis of linear expansion and placed on the other layer, as a result of which the existing angle of inclination α of the webs alternates, as a result of which webs cross and form sections through which a fluid can flow with little back-mixing
Implementation Method 6
