Solution Overview
Problem
Existing thermal management systems are inefficient, bulky, and heavy, limiting their use in high-tech industries due to inadequate thermal conductivity and applicability to outdoor or high-exposure environments, and they primarily focus on dissipating heat from the device rather than protecting it from external heat generation.
Innovation Solution
A device comprising a graphite-like or pyrolytic graphite-like material for thermal conduction and a thermal energy transfer fluid, combined with a support structure such as an aerogel, to efficiently transfer and dissipate thermal energy while protecting against physical damage, optionally incorporating a thermoelectric generator to convert thermal energy into electrical energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional heat transfer methods based on fluid transfer or conduction transfer are used, then thermal energy can be transferred, but the systems are inefficient due to inadequate thermal conductivities of the materials used
Solution Approach 1:
The patent changes the thermal conductivity parameter by introducing graphite-like or pyrolytic graphite-like materials with exceptionally high thermal conductivity values, transforming the thermal transfer capability from inadequate to highly efficient
Solution Approach 2:
The patent employs composite material structures combining graphite-like materials with protective covers and thermal energy transfer fluids, creating a multi-component system that achieves superior thermal management performance
2Loss of energy
If efficient thermal energy management systems are designed, then heat dissipation performance is improved, but the systems become bulky and heavy, limiting their use in aerospace applications
Solution Approach 1:
The patent achieves high thermal conductivity with reduced weight by substituting traditional heavy metal heat sinks with graphite-like materials that offer superior thermal performance at lower density
Solution Approach 2:
The patent applies thermal management functions locally at the protective cover level rather than requiring bulky centralized cooling systems, enabling efficient heat dissipation with minimal weight addition
3Reliability
If traditional cooling systems are designed for controlled environments, then they can dissipate heat effectively, but they are not practical for outdoor or high-exposure environments and cannot protect from external heat generation
Solution Approach 1:
The protective cover integrates multiple functions: physical protection, thermal conduction, and external heat management, making it suitable for both controlled and harsh outdoor environments including aerospace applications
Solution Approach 2:
The patent converts external heat exposure from a harmful factor into a manageable parameter by using the graphite-like material's high thermal conductivity to rapidly channel external heat away from sensitive components
