Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional heat dissipation methods are used, then heat can be removed from the component, but the heat dissipation is not uniform and temperature differences are large
Solution Approach 1:
The patent utilizes phase change material that transitions from solid to liquid and back to solid, absorbing and releasing heat during these phase transitions. This phase change process occurs uniformly throughout the adsorption bed, creating uniform heat dissipation across the component surface and eliminating hot spots while maintaining high heat removal efficiency.
Solution Approach 2:
The adsorption bed acts as an intermediary between the heat-generating component and the environment. It contains phase change material that mediates heat transfer by absorbing heat from the component during phase transition and dissipating it uniformly, thereby solving both the uniformity and efficiency problems simultaneously.
2Productivity
If high heat flux is dissipated quickly, then overheating is prevented, but the heat dissipation rate must be extremely high
Solution Approach 1:
The patent changes the thermal parameters of the heat dissipation system by using phase change material with specific latent heat properties. This allows the system to absorb large amounts of heat flux rapidly during phase transition while maintaining a controlled temperature, achieving high heat dissipation rate without excessive energy loss to the environment.
Solution Approach 2:
The phase change material is pre-positioned in the adsorption bed in a state ready to absorb heat. When heat flux occurs, the material immediately begins phase transition and heat absorption, providing preliminary heat dissipation capacity before the component reaches critical temperatures, thus preventing overheating while managing energy loss.
