Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heat exchanging apparatuses of the falling liquid film type face difficulties in cleaning and maintenance due to the attachment of the heat transfer medium circulation pipe to a housing, which hinders efficient heat exchange and increases labor requirements.
Innovation Solution
A heat exchanging apparatus with a boxy case that includes a heat exchange unit with a spirally wound heat transfer medium circulation pipe, where the pipe is fixed to the inner surface of a lid member via a frame formed by bar-like members, allowing for easy withdrawal and repositioning for maintenance and ensuring uniform contact for enhanced heat exchange efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the heat transfer medium circulation pipe is attached to a housing, then the heat exchange structure is stable and fixed, but it becomes difficult to clean and maintain the pipe
Solution Approach 1:
The heat transfer medium circulation pipe is divided into a fixed end and a movable end, allowing the movable end to be detached from the housing for cleaning and maintenance while the fixed end remains attached to maintain structural stability
Solution Approach 2:
The movable end of the heat transfer medium circulation pipe can be extracted from the housing opening for cleaning and maintenance purposes, while the fixed end remains attached to maintain the heat exchange structure
2Ease of repair
If the heat transfer medium circulation pipe is made movable for maintenance, then cleaning becomes easier, but the positioning accuracy and heat exchange efficiency may deteriorate
Solution Approach 1:
A positioning mechanism acts as an intermediary between the movable end of the pipe and the housing, ensuring that when the pipe is reattached after maintenance, it returns to its precise original position for optimal heat exchange efficiency
Solution Approach 2:
The positioning mechanism ensures that the movable end of the heat transfer medium circulation pipe returns to the same potential position relative to the housing, maintaining consistent heat exchange performance after maintenance

AI summary
A case of a heat exchanging apparatus includes an opening section provided on the sidewall and a plate-like lid member for opening and closing the opening section. A heat exchange section of a heat transfer medium circulation pipe is fixed to the inner surface of a lid member via a frame body formed by combining bar-like members. When the lid member is at a position where the opening section is closed, the heat exchange section of the heat transfer medium circulation pipe is housed fixedly in the case, and when the lid member is at a position where the opening section is open, the heat exchange section of the heat transfer medium circulation pipe is withdrawn from the opening section out of the case. This can reduce labor for cleaning and maintenance of the apparatus effectively and improve efficiency of heat exchange of the apparatus.
