Converter Module Side-Airflow Cooling for Uniform Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing converter cabinets suffer from poor heat dissipation due to non-uniform heat distribution, leading to increased ambient temperatures that can exceed the maximum allowable working temperature of converter modules.
Innovation Solution
A converter module design featuring a heat dissipation passage enclosed by a housing and a converter body, with airflow channels on both sides of the converter body, allowing for simultaneous heat dissipation from multiple angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If heat dissipation is performed only from the bottom of converter modules, then the structure is simple, but the heat dissipation uniformity is poor
Solution Approach 1:
The patent transitions from single-direction (bottom-only) heat dissipation to multi-directional heat dissipation by adding air ducts on both sides of the converter module. This dimensional expansion allows heat to be dissipated from multiple directions simultaneously, achieving uniform temperature distribution without significantly increasing structural complexity.
2Volume of stationary object
If converter modules are stacked in a compact structure, then space utilization is improved, but ambient temperature increases and may exceed maximum allowable working temperature
Solution Approach 1:
The patent introduces air ducts as intermediary structures between stacked converter modules. These air ducts create dedicated heat dissipation channels that actively manage the thermal environment between modules, allowing compact stacking while maintaining ambient temperature below maximum allowable working temperature through controlled airflow.
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 design achieves uniform heat dissipation and improves the overall heat dissipation effect, reducing ambient temperatures and preventing overheating in stacked converter modules.
Implementation Method 1
a fan is mounted in the heat dissipation passage... the heat dissipation airflow can simultaneously dissipate heat for the converter body from the at least two sides
Implementation Method 2
a bottom of each converter module is respectively provided with a heat dissipation fan and a heat dissipater, which are used to dissipate heat for IGBT

AI summary
A converter module, including a housing and a converter body mounted within the housing. The housing and the converter body are joined to form a cooling channel. A fan is mounted in the cooling channel. An air inlet and an air outlet in communication with the cooling channel are provided on the housing. The cooling channel is distributed at two sides of the converter body. In the converter module described above, the housing and the converter body are joined to form the cooling channel, and the cooling channel at least is distributed at either side of the converter body, thus allowing a cooling airflow to cool the converter body from either side, favoring the implementation of even cooling, and increasing the cooling effect.
