Partitioning Wall Plate Cooling for Electronic Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatus cooling systems fail to efficiently cool both components thermally connected to a heat sink and those not connected, as they either inadequately blow air to the heat sink or do not ventilate the entire internal space effectively.
Innovation Solution
The system partitions the internal space into two areas, using a heat sink as a partitioning wall plate and a fan to direct air from the outside into one space and out through another, where a thermal conductor connected to components dissipates heat, while also providing airflow to components not directly connected to the heat sink.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If air blowing is performed for the entire internal space using the fan, then complete ventilation of the internal space is achieved, but sufficient cooling of the heat sink is not achieved
Solution Approach 1:
The internal space is divided into a heat dissipation space and a board-side space using a partitioning wall plate. This segmentation allows different air blowing strategies for different regions: concentrated air blowing for the heat dissipation space to cool the heat sink, and complete ventilation for the board-side space to cool other electronic components.
2Temperature
If concentrated air blowing is implemented by dividing the internal space into heat dissipation space and board-side space, then heat sink cooling is improved, but electronic components not thermally connected to the heat sink are not cooled
Solution Approach 1:
The internal space is divided into a heat dissipation space and a board-side space using a partitioning wall plate. This segmentation allows different air blowing strategies for different regions: concentrated air blowing for the heat dissipation space to cool the heat sink, and complete ventilation for the board-side space to cool other electronic components.
3Productivity
If the fan is installed close to the inlet of the first space or outlet of the second space, then air blowing efficiency is improved, but fan noise leaks to the outside
Solution Approach 1:
The partitioning wall plate serves as an intermediary structure that allows the fan to be installed at a distance from both the inlet of the first space and the outlet of the second space. The through-hole in the partitioning wall plate provides a remote mounting position for the fan, reducing noise leakage while maintaining air blowing efficiency through the flow guide structure.

AI summary
To efficiently cool the internal space of an electronic apparatus. An electronic apparatus includes: a partitioning wall plate (140) that covers a board (110) mounted with an electronic component (100) and forms a first space (160) along with the board (110); a cover member (150) that covers the partitioning wall plate (140) and forms a second space (170) along with the partitioning wall plate (140); and a fan (180) configured to blow air entering from the outside to one of spaces toward the outside through the other space in a predetermined direction, characterized in that the second space (170) is provided with a thermal conductor (140) thermally connected to an electronic component (100) of the first space (160), and a flow guide for guiding the air blowing from the fan (180) to the thermal conductor (140).
