Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for cooling electronic components using radiators face reliability issues due to incompatibility between adhesives and component materials, leading to poor heat transfer and potential mounting errors with mechanical fastening, which compromises the cooling efficiency and operation of electronic equipment.
Innovation Solution
A cooler device with a radiator having fins, where a cover with spring blades is used to mechanically secure the radiator to the electronic component, providing stability and ensuring proper alignment, and allowing air flow for enhanced cooling, with the spring blades exerting forces to maintain contact and return the radiator to a horizontal position if poorly positioned.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If adhesive is used to fasten the radiator to the electronic component, then the mounting process is simplified, but the reliability deteriorates due to incompatibility between adhesive and component material
Solution Approach 1:
The patent replaces the chemical bonding mechanism (adhesive) with a mechanical spring blade system that applies continuous elastic force to press the radiator against the electronic component, eliminating compatibility issues between adhesive and component materials while maintaining secure attachment
Solution Approach 2:
The patent changes the fastening mechanism from a static chemical bond to a dynamic mechanical system where spring blades can adjust their pressing force through elastic deformation, allowing the radiator to maintain reliable contact regardless of material compatibility issues
2Reliability
If mechanical assembly with pin is used to fasten the radiator, then the reliability of retention is improved, but the manufacturing precision deteriorates due to mounting errors
Solution Approach 1:
The patent divides the single pin fastening mechanism into multiple independent spring blades distributed across the radiator base, which collectively provide retention while reducing the impact of individual positioning errors through load distribution and elastic compliance
Solution Approach 2:
The patent transforms the rigid positional constraint of a pin into a compliant elastic contact system where spring blades can accommodate manufacturing tolerances and misalignments through their ability to deform, maintaining reliable retention without requiring high manufacturing precision
3Ease of operation
If the radiator is loosely mounted on the electronic component, then the ease of installation is improved, but the heat transfer efficiency deteriorates
Solution Approach 1:
The patent replaces loose mechanical attachment with a spring-based system that automatically applies optimal pressing force to ensure thermal contact, eliminating the trade-off between installation ease and heat transfer efficiency by making both simultaneously achievable
Solution Approach 2:
The spring blades automatically adjust their pressing force based on the radiator's position and the component's surface characteristics, self-regulating to maintain optimal thermal contact without requiring precise manual adjustment or complex control mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances the reliability and stability of the radiator's mounting, improves heat transfer, and maintains efficient cooling by ensuring consistent contact between the radiator and electronic component, reducing the risk of operational failures and enhancing cooling performance even at high ambient temperatures.
Implementation Method 1
The cover includes a plurality of spring blades, each pressed against a top edge of at least one of the fins in order to hold the radiator pressed against the component
Implementation Method 2
This serves to transfer heat by conduction between the electronic component and the radiator
Implementation Method 3
to transfer heat by convection between the radiator and the air that is used for carrying away the heat produced while the components are in operation
