Movement Support Airflow Channel Layout for Inverter Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inverter welding machines face inefficiencies in heat dissipation due to uniform air volume distribution, which affects the service life of circuit boards and electronic components, as the existing designs do not effectively manage heat dissipation channels and air flow, leading to suboptimal cooling.
Innovation Solution
A movement support with a base featuring a drainage plate that directs air volume into two heat dissipating flow channels, where the first channel has a smaller cross-sectional area and is communicated directly with the air inlet, and the second channel has a larger area, with strategically placed flow guiding bumps to enhance air speed and reduce obstruction, ensuring effective heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a fan is mounted on the movement support to cool the inverter circuit board and electronic parts, then the heat dissipation function is provided, but the air volume is uniformly distributed causing insufficient heat dissipation in some sections
Solution Approach 1:
The patent divides the heat dissipation system into multiple independent flow channels (first heat dissipating flow channel and second heat dissipating flow channel) with different cross-sectional areas. Each channel is equipped with flow guiding bumps to create localized high-speed flow zones. This segmentation allows different sections to receive differentiated air volumes matched to their heat generation characteristics, resolving the contradiction between providing heat dissipation function and avoiding uniform air distribution.
2Speed
If the first heat dissipating flow channel has a smaller cross-sectional area with flow guiding bumps, then the air speed is accelerated for better heat dissipation, but the channel complexity increases
Solution Approach 1:
The patent applies local quality by creating localized high-speed flow zones using flow guiding bumps only in sections requiring enhanced heat dissipation. The bumps are strategically positioned to accelerate air flow precisely where needed, while other channels maintain simpler structures. This localized modification achieves high air speed in critical areas without unnecessarily complicating the entire flow channel system.

Function Achieved in This Case
The solution ensures that air volume is not obstructed, allowing for accelerated air speed and improved heat dissipation, particularly where heat is excessive, thereby extending the service life of inverter circuit boards and electronic components.
Implementation Method 1
A drainage plate is installed on the base on one side of the air inlet. A first heat dissipating flow channel communicated with the air inlet is formed on the base on one side of the drainage plate. A second heat dissipating flow channel communicated with the air inlet is formed on the base on the other side of the drainage plate.
Implementation Method 2
A first heat dissipating flow channel communicated with the air inlet is formed on the base on one side of the drainage plate. A second heat dissipating flow channel communicated with the air inlet is formed on the base on the other side of the drainage plate.
