Rectangular Pressure Vessel End Structure for Simpler Flow Channel Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressure vessels require multiple components for opening and closing structures, increasing manufacturing costs due to the complexity of the design.
Innovation Solution
A pressure vessel design with a single openable and closable longitudinal end surface, featuring a pressure vessel body with integrated flow channels, inlet-outlet ports, and demountable closing members that can be fixed with an inorganic adhesive, made from the same material or with greater thermal expansion, reducing the number of components needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple opening and closing structures are provided on lid members for inspection and maintenance, then accessibility to flow channels is improved, but the number of components and manufacturing cost increase
Solution Approach 1:
The pressure vessel body is divided into multiple longitudinal sections with opening portions at different positions along the longitudinal direction. Each opening portion provides independent access to specific flow channels, allowing targeted inspection and maintenance without requiring multiple lid members or complex opening/closing structures.
Solution Approach 2:
Instead of providing opening and closing structures on lid members (horizontal dimension), the patent introduces opening portions along the longitudinal direction (vertical dimension) of the pressure vessel body. This dimensional shift allows direct access to flow channels from the side, eliminating the need for complex lid member mechanisms.

AI summary
A pressure vessel comprises a pressure vessel body having a rectangular cross-sectional shape and formed to extend in the direction of flow of fluids, and the pressure vessel body includes a first flow channel which is formed in the longitudinal direction of the pressure vessel body and through which a first fluid is caused to flow, a second flow channel which is formed in the longitudinal direction of the pressure vessel body and through which a second fluid is caused to flow, a first-fluid inlet-outlet port which is provided in one longitudinal end surface of the pressure vessel body and connects with the first flow channel and through which the first fluid is caused to flow in or out, a second-fluid inlet-outlet port which is provided in the other longitudinal end surface of the pressure vessel body and connects with the second flow channel and through which the second fluid is caused to flow in or out, an opening portion which is provided in the one longitudinal end surface of the pressure vessel body and connects with the second flow channel, and a closing member which closes the opening portion in a demountable manner.
