Outdoor Electronic Device Heat Dissipation via Hollow Rod Body
Solution Overview
Problem
Outdoor electronic devices face challenges in balancing heat dissipation and waterproofness, as the increasing heat generated by electronic assemblies during operation can lead to performance issues and damage, especially when used in outdoor environments.
Innovation Solution
The design incorporates a hollow rod body with a blower fan that pumps hot air from the electronic assemblies into the rod body for heat exchange, utilizing a high-thermal-conductivity material and a vertical arrangement to facilitate natural air circulation and heat dissipation without compromising waterproofness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If ventilation holes are provided in the shell for heat dissipation, then heat dissipation effect is improved, but waterproofness deteriorates
Solution Approach 1:
The rod body acts as an intermediary heat exchange structure. Instead of directly ventilating the shell where electronic assemblies are located, hot air is pumped into the rod body which serves as a separate heat exchange chamber. The rod body's large surface area enables efficient heat dissipation to the surrounding environment while the shell remains sealed and waterproof.
2Productivity
If the number of electronic assemblies is increased to improve device performance, then device functionality is improved, but heat generation increases
Solution Approach 1:
The patent transitions from two-dimensional heat dissipation (surface ventilation holes on the shell) to three-dimensional heat exchange by introducing the rod body as a volumetric heat exchange structure. The rod body's extended structure provides substantially larger heat exchange surface area, enabling effective heat dissipation even with multiple heat-generating electronic assemblies inside the sealed shell.
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 effectively manages heat dissipation, ensuring the normal operation and stability of outdoor electronic devices while maintaining waterproofness, even in harsh outdoor conditions, by using a blower fan to exchange heat with a large-area rod body and promoting natural air circulation.
Implementation Method 1
hot air generated by the electronic assemblies in the outdoor electronic device during operation can be pumped by the air inlet port of the blower fan. The hot air is pumped by the blower fan and then is discharged to the rod body by the air outlet port. The hot air pumped into the rod body by the blower fan is in contact with the large-area rod body for heat exchange.
Implementation Method 2
the above rod body is made of a high-thermal-conductivity material
Implementation Method 3
cold air in the rod body can be naturally circulated and supplemented into the shell
