Semiconductor Cooler Partition Wall for Better Coolant Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coolers for semiconductor devices face inefficiencies due to the radiator interfering with the coolant flow direction, leading to reduced energy in the coolant flow and insufficient distribution, which in turn decreases the cooling efficiency.
Innovation Solution
The cooler design includes a housing with a partition wall that creates separate reservoirs for coolant flow, featuring an overflow section that allows coolant to flow over it, reducing interference with the coolant flow and enhancing hydraulic head, thus improving coolant distribution and cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the radiator is attached to the housing to close the opening, then the semiconductor device can be cooled through the radiator, but the radiator interferes with the flow direction of the coolant, reducing energy in the coolant flow and leading to insufficient distribution of coolant throughout the radiator
Solution Approach 1:
The internal space is divided into a first reservoir and a second reservoir using a partition wall, allowing the coolant to flow through separate paths. This segmentation enables the coolant to reach different portions of the radiator more effectively without interference from the radiator structure itself
Solution Approach 2:
The partition wall extends in the first direction from the bottom toward the opening, creating a three-dimensional flow path structure. This dimensional arrangement allows the coolant to flow over the overflow section and into the second reservoir, bypassing the interference issue in the original linear flow path
2Quantity of substance
If the radiator interferes with the flow direction of the coolant, then the radiator can be positioned to close the opening, but this reduces energy in the flow of coolant which may lead to insufficient distribution of coolant throughout the entire portion of the radiator
Solution Approach 1:
The partition wall is positioned to create an overflow section that directs coolant flow in advance into the second reservoir. This preliminary flow direction control ensures that coolant reaches the entire radiator portion before any potential energy loss occurs
Solution Approach 2:
The partition wall acts as an intermediary structure that guides the coolant flow from the first reservoir over the overflow section into the second reservoir. This intermediary element enables coolant distribution without the radiator directly interfering with the flow path

AI summary
A cooler includes: a housing that includes an opening, an internal space, and a bottom; and a partition wall that rises in a first direction from the bottom and that is accommodated in the internal space. The housing includes an inlet channel and an outlet channel that are connected to the internal space. The internal space includes a first reservoir and a second reservoir that are partitioned by the partition wall. The first reservoir is connected to the inlet channel. The second reservoir is connected to the outlet channel. The partition wall includes an overflow section that overlaps with the opening as viewed in the first direction and is farthest from the bottom. The overflow section is located between the bottom and the opening.
