Press Element Heat Dissipation for Compact Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices like notebook computers face insufficient heat dissipation efficiency due to compact designs that often rely solely on heat pipes without fans, leading to potential system overheating.
Innovation Solution
An electronic device with a press element and supporting layer that creates a chamber with connected openings, allowing air to flow in and out through elastic deformation, enhancing heat dissipation by increasing pressure to push hot air out and drawing in cooler air when restored.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If heat dissipation fan is removed to reduce device complexity and weight, then portability is improved, but heat dissipation efficiency deteriorates
Solution Approach 1:
The press element is periodically pressed and released to create periodic air flow through the chamber. This periodic compression and expansion of air drives continuous heat dissipation without requiring a rotating fan, converting intermittent user input into sustained cooling action.
Solution Approach 2:
The elastic portion stores mechanical energy when pressed and automatically releases it to drive air flow when released. The system uses its own elastic deformation mechanism to generate the driving force for air flow, eliminating the need for external power sources or motorized components.
2Volume of moving object
If compact design is used to reduce device volume, then portability is improved, but heat dissipation capability deteriorates
Solution Approach 1:
The heat dissipation function is segmented from the main device body into a separate press element with chamber structure. This allows the heat dissipation mechanism to be integrated into compact spaces without increasing overall device volume, as the press element can be positioned over existing heat-generating components.
Solution Approach 2:
The press element utilizes vertical compression along the Z-axis to drive horizontal air flow through the chamber. By converting vertical pressure into horizontal airflow, the mechanism achieves effective heat dissipation in a compact footprint without requiring additional lateral space for traditional fan assemblies.
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 method improves heat dissipation efficiency by continuously providing airflow with low-temperature air, effectively managing heat in compact electronic devices without the need for fans.
Implementation Method 1
When the press element is pressed and elastically deformed, a volume of the chamber is decreased
Implementation Method 2
pressure inside the chamber is increased so that air inside the chamber flows to inside the main body
Implementation Method 3
when the press element is stopped being pressed and restored, volume of the chamber is increased
Implementation Method 4
pressure inside the chamber is decreased so that the low-temperature air from the outside flows to inside the chamber
Implementation Method 5
air inside the chamber flows to inside the main body through the first opening... continuously providing airflow with low-temperature air

AI summary
An electronic device including a main body, a supporting layer and at least one press element is provided. The main body has an inner space. The supporting layer is disposed on the main body and covers the inner space, wherein the supporting layer has at least one first opening. The press element is disposed on the supporting layer and has a chamber and at least one second opening, wherein the first opening and the second opening are connected to the chamber. When the press element is pressed and elastically deformed, air inside the chamber flows to the inner space through the first opening. When the press element is stopped being pressed and restored, air outside the chamber flows to inside the chamber through the second opening. In addition, a heat dissipation method adapted to the electronic device is also provided.
