Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional semiconductor coolers with fine cooling fins are prone to clogging due to foreign matter and fine particles in the coolant, leading to a deterioration in cooling performance.
Innovation Solution
A cooler design featuring a heat radiating member, a flow path forming member with protruding fin members, and a trap part with recesses on its inner surface, which directs foreign matter and particles away from the fin members, preventing clogging and maintaining cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If multiple cooling fins are provided in the coolant flow path, then heat transfer efficiency is improved, but clogging due to fine particles or foreign matter is likely to occur
Solution Approach 1:
The flow path forming member is divided into multiple flow paths, with each flow path containing cooling fins. This segmentation allows the introduction of trap parts in the spaces between adjacent flow paths, creating dedicated areas for particle collection that do not interfere with the heat transfer function of the fins while preventing clogging in the coolant flow channels.
Solution Approach 2:
Trap parts are introduced as intermediary structures between the cooling fins and the coolant flow path. These trap parts act as mediators that capture fine particles and foreign matter before they can reach and clog the cooling fins, while still allowing coolant to flow freely through the system for effective heat transfer.
2Productivity
If fine configuration cooling fins are used, then cooling performance is improved, but foreign matter accumulation is more likely
Solution Approach 1:
Trap parts are positioned upstream or at strategic locations within the flow path to preliminarily capture foreign matter and fine particles before they can accumulate on the cooling fins. This preliminary action prevents the harmful accumulation on the fine-configured fins while preserving their high cooling performance.
Solution Approach 2:
The trap parts are strategically positioned in specific locations within the flow path where foreign matter is likely to settle or be carried by the coolant flow. This local placement ensures that the trap parts effectively intercept particles without interfering with the overall cooling function of the fin structure.

AI summary
A cooler includes a heat radiating member and a cover member that form a coolant flow path. The heat radiating member has a first surface on which an object to be cooled is disposed. The heat radiating member includes multiple fin members protruding into the coolant flow path from a second surface of the heat radiating member. The second surface of the heat radiating member is a part of a surface of the coolant flow path. The cover member includes a trap part in which multiple recesses are formed in a portion of an inner surface of the cover member being another part of the surface of the coolant flow path outside a protruding direction of the fin members.
