Solution Overview
Problem
Existing cryogenic vessel pressure control methods require complex structures and high costs due to the use of heat exchangers and corresponding pipes and valves for pressurization.
Innovation Solution
A pressurizing device for cryogenic vessels that utilizes a rotatable heat conducting member to transfer heat from the shell to the inner vessel, achieving pressure increase through vaporization without the need for additional heat exchangers or pipes, using a simple structure and low-cost components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heat exchange methods with heat exchangers, pipes and valves are used for pressurization, then pressurization function is achieved, but device complexity and cost increase
Solution Approach 1:
The patent extracts and eliminates the heat exchanger, pipes and valves from the pressurization system. Instead of using these separate components, the invention uses the vacuum insulation layer itself as the heat transmission path, directly connecting the outer shell to the inner vessel to achieve pressurization without additional equipment.
Solution Approach 2:
The vacuum insulation layer serves dual functions: it provides thermal insulation for cryogenic storage while simultaneously serving as a heat transmission path for pressurization when needed. This multi-functionality eliminates the need for dedicated pressurization equipment.
2Reliability
If heat exchangers and corresponding pipes and valves are used for pressure control, then pressure control is achieved, but manufacturing cost increases
Solution Approach 1:
The patent removes the need for expensive heat exchangers, pipes and valves by utilizing the existing vacuum insulation structure. This extraction of unnecessary components directly reduces manufacturing costs while maintaining pressure control capability.
Solution Approach 2:
The vacuum insulation layer serves itself by providing both insulation and pressurization functions. The system uses its own structural components for dual purposes, eliminating the need for additional specialized equipment and reducing overall manufacturing cost.
