Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heat dissipating modules in electronic devices face inefficiencies due to the distance between the fan and the heat dissipating fin, which reduces air flow speed and increases module size, hindering effective heat transfer and miniaturization.
Innovation Solution
A heat dissipating module with a Y-shaped heat transfer path design, utilizing a heat conducting element composed of a first conductive component and two second conductive components, where the first component engages with the heating element and the second components engage with the heat dissipating fin, allowing for direct heat transfer and reduced distance between the fan and the fin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fan is disposed separately from the heat dissipating fin to allow the heating element to be arranged therebetween, then the heating element can be effectively cooled, but the distance between the fan and the heat dissipating fin increases, reducing air flow speed and increasing module size
Solution Approach 1:
The patent repositions the heating element from being located between the fan and heat dissipating fin (linear arrangement) to being adjacent to the heat dissipating fin in a different spatial dimension. The fan blows air along the heat dissipating fin surface, creating an effective cooling path without requiring the heating element to be positioned in the direct air flow path between fan and fin. This dimensional reconfiguration reduces the distance between fan and fin while maintaining cooling effectiveness.
2Reliability
If the fan blows air parallel to the first direction through the heating element before reaching the heat dissipating fin, then the heating element receives cooling air, but the air flow speed decreases considerably by the time it reaches the heat dissipating fin
Solution Approach 1:
The patent segments the cooling function into two distinct paths: (1) the fan blows air that directly contacts and cools the heating element, and (2) the fan also blows air along the heat dissipating fin surface. This segmentation allows the heating element to receive cooling air without the air flow needing to travel through the element, thereby maintaining higher air flow speed when the air reaches the heat dissipating fin for effective heat dissipation.
3Ease of operation
If the air flow is blocked and diverted by about 90 degrees by the wall structure, then the air flow direction is changed to reach the heat dissipating fin, but the path length increases and heat dissipation performance is adversely affected
Solution Approach 1:
Instead of using wall structures to block and divert air flow at 90 degrees (indirect path), the patent inverts the approach by directly positioning the heat dissipating fin to face the air outlet of the fan. The fin is oriented with its air intake side facing the fan's air outlet, allowing air to flow directly from the fan through the fin without requiring 90-degree diversions or extended path lengths. This direct facing arrangement eliminates the need for complex wall structures and minimizes air flow path length.
