Condenser with Spiral Cooling Pipe to Shorten Vacuum Drying Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum cleaning devices have limitations in shortening the drying time of workpieces due to inadequate condensation performance in the drying chamber, which affects productivity.
Innovation Solution
The condenser incorporates a cooling pipe spirally wound within a dual-shell container structure with a steam intake opening, featuring a central opening that faces the steam intake and a surface with vertically arranged fins, enhancing coolant circulation and steam condensation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a conventional condenser structure is used in the drying chamber, then the device complexity is low, but the condensation performance is insufficient leading to long drying time
Solution Approach 1:
The condenser is segmented into multiple functional components: a container with steam intake opening, a spirally wound cooling pipe for coolant circulation, and vertically arranged fins for enhanced heat dissipation. This segmentation allows each component to perform its specific function efficiently, improving overall condensation performance while maintaining manageable complexity
Solution Approach 2:
The cooling pipe is configured in a spiral form rather than a straight line, adding a dimensional aspect to the coolant flow path. This spiral configuration increases the surface area for heat exchange and improves condensation efficiency without significantly increasing device complexity
2Temperature
If the drying chamber temperature is maintained at a lower temperature, then the condensation performance is improved, but the energy consumption increases due to additional cooling requirements
Solution Approach 1:
The condenser structure enables the drying chamber to self-regulate its temperature through the phase change of steam. When steam enters the drying chamber and contacts the cooling pipe and fins, it naturally condenses and releases latent heat, which is then dissipated by the circulating coolant. This self-service mechanism maintains lower temperature without requiring active cooling energy input
Solution Approach 2:
The condenser utilizes the phase transition of steam from gas to liquid form. When steam contacts the cooling pipe and fins, it undergoes condensation, releasing latent heat that is efficiently transferred to the coolant. This phase transition process naturally maintains the drying chamber at a lower temperature while the energy is carried away by the coolant circulation
