Cooling Device Bypass Flow Path for Gaseous Air Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cooling efficiency is degraded in layered electronic device systems due to dissolved air in the coolant becoming gaseous and accumulating in the water-supply pipe, leading to reduced cooling performance, especially for upper devices in up-down configurations.
Innovation Solution
A cooling device with a bypass flow path connected to the top edge of the water-supply pipe to divert gaseous air away from the coolers, combined with a circulation system that includes a pump and coolant cooler to maintain coolant flow and efficiency, and branch pipes to distribute coolant effectively across multiple electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If coolant is circulated through the water-supply pipe to cool multiple electronic devices, then cooling coverage is improved, but gaseous air accumulates in the upper portion of the water-supply pipe and degrades cooling efficiency
Solution Approach 1:
The invention extracts and removes gaseous air from the coolant flow path by providing a vent port at the upper portion of the water-supply pipe. This allows accumulated gaseous air to escape through the vent port rather than being forced through the coolers, thereby maintaining cooling efficiency while preserving comprehensive cooling coverage across multiple electronic devices.
Solution Approach 2:
The bypass flow path acts as an intermediary channel that diverts gaseous air away from the main cooling circuit. By providing this alternative path, the system allows gas to be separated from the coolant flow without disrupting the overall cooling function, thus resolving the contradiction between maintaining cooling coverage and preventing efficiency degradation.
2Quantity of substance
If electronic devices are arrayed in a layered shape in up-down direction to save space, then device density is improved, but cooling efficiency of upper electronic devices is degraded due to gaseous air accumulation
Solution Approach 1:
The vent port positioned at the upper portion of the water-supply pipe extracts gaseous air that naturally accumulates at the highest point in the system. This extraction mechanism specifically protects upper electronic devices in vertical arrays by preventing gas-laden coolant from reaching them, thereby maintaining both high device density and reliable cooling efficiency for upper devices.
3Device complexity
If a simple water-supply pipe system is used without bypass flow path, then device complexity is reduced, but gaseous air enters coolers and degrades cooling performance
Solution Approach 1:
The vent port provides a simple yet effective extraction mechanism for removing gaseous air from the water-supply pipe system. This minimal addition to the pipe system architecture achieves gas removal without requiring complex pumps, valves, or separation devices, thus maintaining low device complexity while significantly improving cooling performance reliability.

AI summary
An electronic device system that includes electronic devices and a cooling device to cool an object of the electronic devices. The cooling device includes coolers; a water-supply pipe that has branch pipes and supplies a coolant to the coolers, each of the branch pipes being coupled with each of the coolers; a waste pipe that has branch pipes, each of which is coupled with each of the coolers; a circulation pipe that couples an inlet of the water-supply pipe with an outlet of the waste pipe and has a pump to discharge the coolant and a coolant cooler to cool the coolant; and a bypass flow path that is coupled with at least a top edge portion of the water-supply pipe, bypasses the plurality of coolers, and is coupled with the waste pipe. The coolant having passed through the coolers is exhausted to the waste pipe.
