Plug-Type Fan Holder for Compact Refrigerator Condenser Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigeration appliances, such as domestic refrigerators, require a large machine compartment to accommodate the fan assembly due to the distance between the condenser and the fan, leading to reduced utilizable volume and increased noise from high fan speeds to compensate for cooling performance loss.
Innovation Solution
A plug-type holder that securely attaches the fan assembly directly to the refrigerant tube of the condenser using projections or screw holes, reducing the need for a large evaporator tray and allowing for lower fan rotational speeds, thereby enhancing cooling performance and reducing noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the fan assembly is positioned at a distance from the condenser, then the machine compartment volume is increased, but the cooling performance decreases and noise increases
Solution Approach 1:
The holder is divided into a separate body portion and a plug portion that can be attached to the condenser. This segmentation allows the holder to be positioned close to the condenser while maintaining structural integrity, enabling compact arrangement of components without compromising cooling performance.
Solution Approach 2:
The plug-type holder acts as an intermediary component between the fan assembly and the condenser. It provides a secure mounting point directly on the condenser, allowing the fan assembly to be positioned in close proximity while maintaining stability and effective cooling.
2Volume of moving object
If the fan assembly is positioned at a distance from the condenser, then the machine compartment volume is increased, but the noise level increases
Solution Approach 1:
The holder is divided into a separate body portion and a plug portion that can be attached to the condenser. This segmentation allows the holder to be positioned close to the condenser while maintaining structural integrity, enabling compact arrangement of components without compromising cooling performance.
Solution Approach 2:
The holder integrates multiple functions: it serves as both the mounting structure for the fan assembly and the attachment mechanism to the condenser. This merging of functions allows for a compact design that reduces the distance between the fan and condenser, thereby reducing noise.
3Ease of manufacture
If the holder is integrally provided with the evaporator tray, then the manufacturing is simplified, but the space between condenser and fan assembly increases
Solution Approach 1:
The holder is divided into a body portion and a plug portion that can be separately manufactured and then assembled. The plug portion attaches directly to the condenser, allowing the fan assembly to be positioned close to the condenser without requiring the entire holder to be integrally formed with the evaporator tray.
Solution Approach 2:
The plug portion is extracted from the integral holder structure and made as a separate attachable component. This allows the holder to be positioned independently on the condenser, reducing the distance to the fan assembly while maintaining ease of manufacture through modular construction.
4Reliability
If the fan assembly is positioned close to the condenser, then the cooling performance is improved, but the holder structure becomes more complex
Solution Approach 1:
The holder is divided into a body portion and a plug portion that can be separately manufactured and assembled. This segmentation simplifies the overall structure by allowing each component to be optimized independently, reducing complexity while enabling close positioning of the fan assembly to the condenser for improved cooling.
Solution Approach 2:
The plug-type holder serves multiple functions: it provides structural support for the fan assembly, acts as an attachment mechanism to the condenser, and enables compact positioning. This multi-functionality reduces the need for additional components, thereby reducing overall structural complexity.
