Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spiral finned condensers face issues with inefficiency in heat dissipation due to fin damage and deformation caused by direct clamping, leading to reduced cooling performance and increased costs associated with larger volumes.
Innovation Solution
A spiral finned condenser design featuring a wavy inner fin structure and smooth outer fin for uniform heat dissipation, along with a fixing bracket that clamps onto the condensing pipe rather than the fins, ensuring stability and preventing deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If a small condenser is adopted, then volume and cost are reduced, but dissipation performance degrades
Solution Approach 1:
The patent transitions from traditional linear or planar fin arrangements to a three-dimensional spiral configuration. The condensing pipe forms a spiral structure with multiple loops, and the fins wrap around the pipe in a spiral pattern, utilizing spatial volume more efficiently. This dimensional change allows the compact condenser to achieve sufficient heat dissipation surface area within a reduced volume, resolving the contradiction between small size and dissipation performance.
2Ease of manufacture
If direct clamping is used to fix the condenser, then assembly is simplified, but fin damage and deformation occur
Solution Approach 1:
The patent introduces a fixing bracket as an intermediary component between the clamping mechanism and the fins. The bracket is designed to clamp onto the condensing pipe rather than directly contacting the fins, thereby transmitting fixing forces away from the delicate fin structures. This intermediary element enables secure assembly while protecting fin integrity, resolving the contradiction between assembly simplicity and fin reliability.
3Ease of manufacture
If uniform fin structure is used, then manufacturing is simplified, but heat dissipation efficiency is reduced
Solution Approach 1:
The patent implements non-uniform fin spacing and dimensions optimized for different locations along the spiral pipe. Fins closer to the pipe center have different characteristics than those on outer loops, where spacing and dimensions are adjusted to account for variations in heat transfer conditions and airflow patterns. This localized optimization enhances overall heat dissipation efficiency while remaining compatible with manufacturing processes, resolving the contradiction between manufacturing simplicity and heat dissipation performance.
