Solution Overview
Problem
Current cooling devices in data centers require two pumping systems for cooling medium replenishment and recovery, increasing maintenance costs and complexity.
Innovation Solution
A diversion system with a single pumping apparatus that utilizes multiple pipelines and operating modes to manage cooling medium circulation, allowing for both replenishment and recovery, as well as filtration, by selectively opening and closing pipelines under controller guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two pumping systems are used for cooling medium replenishment and recovery, then the cooling medium management function is complete, but the maintenance cost and system complexity increase
Solution Approach 1:
The single pumping apparatus is designed to perform multiple functions: it can pump cooling medium from the storage tank to the cooling device for replenishment, and from the cooling device to the storage tank for recovery. The controller directs the pump to different operational modes (first mode for replenishment, second mode for recovery) to achieve complete cooling medium management with one apparatus instead of two
Solution Approach 2:
The system dynamically switches the pumping apparatus between different operational modes based on the cooling medium volume in the cooling device. The controller monitors the volume and automatically switches between first pumping mode (replenishment) and second pumping mode (recovery), allowing the single pump to adapt to different functional requirements throughout operation
2Adaptability or versatility
If two pumping systems are used for cooling medium replenishment and recovery, then the cooling medium management function is complete, but the maintenance cost increases
Solution Approach 1:
The patent merges the functions of two separate pumping systems into one integrated pumping apparatus. By combining the replenishment pump and recovery pump into a single unit that can operate in different modes, the system reduces the number of components that require maintenance, thereby lowering maintenance costs while maintaining complete cooling medium management functionality
3Ease of repair
If a single pumping apparatus is used with multiple pipelines, then maintenance cost is reduced, but the pipeline control complexity increases
Solution Approach 1:
The controller acts as an intermediary that manages the complexity of pipeline control. It receives input from the volume detection unit and automatically determines which pipelines to activate and in what mode to operate the pumping apparatus. This intermediary control layer simplifies the overall system operation by handling the decision-making for pipeline configuration based on real-time cooling medium volume
