Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling systems in data centers and server rooms are vulnerable to failures, leading to overheating and potential shutdowns, as they rely on extensive HVAC systems that can malfunction or experience temporary shutdowns, posing risks to IT system reliability due to heat sensitivity of computer equipment.
Innovation Solution
A cooling apparatus integrated into server racks or electronic equipment cabinets, featuring a reservoir with a cooling solution and louvers that distribute the solution through ventilation slots, activating upon temperature threshold detection to cool incoming air, and optionally using a flexible material to enhance cooling distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If HVAC systems are used for cooling servers, then cooling effectiveness is improved, but system reliability deteriorates due to vulnerability to failures and shutdowns
Solution Approach 1:
The cooling system is divided into two independent parts: a reliable passive emergency cooling system integrated into the rack and a primary active HVAC system. This segmentation ensures that if the HVAC system fails, the passive cooling system can independently maintain server temperature, resolving the contradiction between cooling effectiveness and reliability.
Solution Approach 2:
The patent implements beforehand cushioning by pre-installing a passive emergency cooling system within the server rack that activates automatically when temperature exceeds a threshold or HVAC fails. This pre-prepared cooling mechanism cushions against the potential harm of HVAC failure, ensuring continuous operation without interruption.
2Reliability
If passive emergency cooling system is added to the rack, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the emergency cooling function from the complex HVAC system and implements it as a simple, self-contained passive cooling mechanism within the rack. This extraction isolates the reliability function into a separate, simpler system that does not add significant complexity to the overall device.
Solution Approach 2:
The passive emergency cooling system is designed to be self-service, automatically detecting temperature conditions and activating cooling without requiring external control systems or complex management. This self-service approach improves reliability while minimizing the addition of complexity compared to manually controlled systems.
3Temperature
If active cooling systems are used continuously, then temperature control is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic action by designing the passive emergency cooling system to activate only when temperature exceeds a predetermined threshold or HVAC fails, rather than operating continuously. This periodic activation maintains temperature control effectiveness while significantly reducing energy consumption compared to continuous active cooling.
Solution Approach 2:
The system changes its operational parameters based on temperature conditions, transitioning from passive (low energy) to active cooling only when necessary. This parameter change approach allows the system to maintain effective temperature control during emergencies while minimizing energy consumption during normal operation.

AI summary
An apparatus for cooling warm air, including a rack containing one or more ventilation slots; a reservoir connected to the rack that contains a cooling solution; and a plurality of components, located within the rack, that receive and distribute the cooling solution from the reservoir. The plurality of components consist of at least one of the following structures: one or more hollow vertical louvers, one or more hollow horizontal louvers, one or more hollow diagonal louvers, and one or more hollow cylindrical louvers. Additionally, the plurality of components may comprise a flexible material that descends from a top portion of the rack, directly below the reservoir, at the same time that an activation component causes the cooling solution to flow from the reservoir into the flexible material.
