Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooling devices for electronic modules in household appliances, such as tumble dryers and washing machines, require significant installation space and additional components, like fans, to effectively dissipate heat from drive motors, which is inefficient and space-consuming.
Innovation Solution
A cooling device with a base body featuring a heat-dissipating graphite material applied as a film or powder coating on a compact, preferably plastic or metal base body, allowing for efficient heat transfer and dissipation with minimal installation space, and the option to use the base body as both a cooling element and a housing wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional cooling devices with fans and heat sinks are used, then heat dissipation is achieved, but installation space is significantly increased and device complexity is increased
Solution Approach 1:
The patent combines the base body and cooling function into a single integrated component. The graphite material is applied directly to the base body, merging the structural support function with the heat dissipation function, eliminating the need for separate heat sinks and fans.
Solution Approach 2:
The patent replaces the mechanical fan-based cooling system with a passive thermal conduction system using graphite material. This substitutes active mechanical cooling with passive thermal management, reducing device complexity and installation space while maintaining heat dissipation effectiveness.
2Temperature
If conventional cooling devices with fans and heat sinks are used, then heat dissipation is achieved, but device complexity and additional components are required
Solution Approach 1:
The patent merges multiple functions into the base body component itself. The base body serves as both the structural support and the heat dissipation element, with graphite material applied directly to it, eliminating the need for separate fans, heat sinks, and mounting hardware.
Solution Approach 2:
The graphite-coated base body provides self-service cooling by conducting heat away from electronic components through its inherent thermal conductivity. The system requires no external power source or control mechanisms, as the heat dissipation occurs passively through thermal conduction.
3Ease of manufacture
If graphite material is applied as a film, then application is easy and reversible, but manufacturing precision may be compromised
Solution Approach 1:
The patent offers flexibility in graphite material application by allowing different forms (film or powder) and thicknesses. The film application method enables easy installation and removal, while the powder form allows for site-specific application with controlled layer thickness, accommodating different manufacturing precision requirements.
