Innovation Solution
An intelligent cooling system utilizing a complex compound sorbent, such as ammonia with CaCl2, MgCl2, CoCl2, or SrCl2, coupled with a burst mode controller to manage absorption and desorption periods for rapid cooling, and an auxiliary cooling/heating system to maintain thermal loads, employing a robust gas distribution mechanism that optimizes reaction rates and system efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ceramic distributors are used to distribute gas to the complex compound, then gas distribution efficiency is improved, but the system becomes fragile and prone to fracture in non-stationary environments
Solution Approach 1:
The patent replaces fragile ceramic distributors with flexible hoses that can be easily replaced. The flexible hoses are designed to be durable enough for practical use but can be swapped out when worn, avoiding the complexity and fragility of ceramic structures while maintaining gas distribution functionality.
Solution Approach 2:
The patent employs flexible hoses instead of rigid ceramic distributors. These flexible hoses can bend and adapt to vibrations and movements in non-stationary environments, preventing fracture while still effectively distributing gas to the complex compound sorbent.
2Ease of manufacture
If cloth distributors are used to distribute gas to the complex compound, then ease of manufacture is improved, but the system becomes prone to clogging after multiple cycles
Solution Approach 1:
The patent uses flexible hoses with smooth internal surfaces to distribute gas. These hoses resist clogging better than cloth distributors while remaining easy to manufacture and install. The smooth interior prevents particulate accumulation that would cause clogging in cloth-based distributors.
3Power
If absorption period is shortened to increase power density, then energy delivery rate is improved, but the system requires more frequent cycling increasing complexity
Solution Approach 1:
The patent employs periodic absorption and desorption cycles of the complex compound sorbent to deliver cooling in bursts. By optimizing the cycle timing and using the natural absorption/desorption characteristics of the sorbent material, the system achieves high power density during absorption phases while allowing sufficient time for passive desorption, reducing the need for complex active control mechanisms.
