Vertical Heat Dissipating Device for Portable Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices, such as notebook computers, face challenges in heat dissipation due to the limited space for heat dissipating fans, leading to increased temperatures around the casing and discomfort for users.
Innovation Solution
A heat dissipating device is integrated into the casing with air flow channels between the device and the casing, utilizing gaps between the heat dissipating device and the casing to direct cool air and prevent heat from contacting the casing, while heat dissipating fins and heat pipes enhance heat removal through strategically placed openings and inlets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heat dissipating fan is disposed in the casing to blow cool air into the heat dissipating fins, then heat dissipation function is provided, but the space for the fan becomes limited and it can only be disposed at the palm rest area
Solution Approach 1:
The patent transitions from a conventional horizontal fan arrangement to a vertical heat dissipating device configuration. The fan blows air upward through heat dissipating fins arranged vertically, utilizing the vertical dimension for heat dissipation rather than the traditional horizontal layout. This dimensional change allows the heat dissipating device to be integrated into the casing without occupying the palm rest area, resolving the space limitation while maintaining effective heat dissipation function.
2Reliability
If the heat dissipating fan blows hot air from the heat dissipating fins out of the casing, then heat is removed from the device, but temperature increases around the casing causing user discomfort
Solution Approach 1:
The patent extracts the heat dissipation function from the traditional fan-only configuration and separates it into a dedicated vertical heat dissipating device. This device includes heat dissipating fins and a fan that work together as an integrated unit, allowing hot air to be expelled through a specific exhaust opening rather than being blown out from the general casing area. This extraction prevents hot air from contacting the palm rest area, eliminating the temperature increase issue while maintaining effective heat removal.
3Reliability
If the heat dissipating device is integrated into the casing with gaps for air flow, then cool air is directed through the device to remove heat, but the device structure becomes more complex
Solution Approach 1:
The patent merges the fan and heat dissipating fins into a single integrated vertical heat dissipating device. The fan is positioned at the bottom of the device, and the heat dissipating fins are arranged vertically above it, forming a unified structure that combines air intake, heat dissipation, and air exhaust functions. This merging simplifies the overall device structure compared to separate components while maintaining effective heat dissipation through the integrated gaps and air flow channels.
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 configuration effectively isolates heat from the casing, preventing temperature increases and user discomfort by efficiently directing cool air to remove heat away from the device, maintaining a comfortable surface temperature.
Implementation Method 1
The heat dissipating device includes a plurality of heat dissipating fins and at least one heat pipe
Implementation Method 2
air flow channels formed via the gaps exist between the outer surface of the heat dissipating device and the inner surface of the casing... the cool air from the fan flows through the air flow channel to isolate the heat of the heat dissipating device
Implementation Method 3
The fan is disposed in the casing... The heat dissipating device is disposed in the casing and at a side of an air outlet of the fan... the cool air from the fan flows through the air flow channel
