Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cooling systems for data centers and telecommunications equipment are inefficient, leading to significant energy wastage and thermal failures due to the mixing of cooling air with warmer air, resulting in inadequate cooling of electronic components, especially in high-density installations where airflow is compromised by equipment configuration and infrastructure limitations.
Innovation Solution
A system that reduces the volume of the cooled environment and controls airflow by using airtight enclosures and pressure differentials to ensure that cooling air is delivered directly to electronic components without mixing with warmer air, increasing airflow volume and temperature consistency across all equipment surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the volume of the cooled environment is reduced using airtight enclosures, then cooling efficiency is improved and energy consumption is reduced, but device complexity increases
Solution Approach 1:
The data center environment is segmented into multiple isolated cooled zones using airtight enclosures around individual equipment racks or groups of racks. Each enclosure creates a separate controlled environment that prevents mixing of cooled and warm air, allowing independent cooling optimization for each zone and reducing overall energy consumption.
Solution Approach 2:
Airtight enclosure walls act as intermediaries that physically separate cooled and warm air streams. These enclosures include sealed doors, gaskets, and isolation mechanisms that prevent air leakage, ensuring that cooling energy is not wasted on the entire facility volume but only on the specific equipment requiring cooling.
2Temperature
If airtight enclosures are used to prevent mixing of cooling air with warm air, then temperature consistency is improved, but ease of operation deteriorates due to restricted access
Solution Approach 1:
The airtight enclosures incorporate dynamic sealing mechanisms including gaskets that compress during door opening/closing operations, and isolation doors that can be opened for equipment access while maintaining the sealed environment when closed. These dynamic elements allow temporary breach of the seal during maintenance while preserving temperature consistency during normal operation.
3Productivity
If cooling airflow volume is increased to deliver more cold air to equipment, then cooling efficiency is improved, but use of energy worsens due to higher fan power requirements
Solution Approach 1:
Cooling airflow is optimized locally within each airtight enclosure rather than attempting to cool the entire facility uniformly. The enclosed spaces allow for targeted airflow delivery directly to heat-generating equipment surfaces, maximizing the cooling effect per unit of fan power and improving overall cooling efficiency without excessive energy consumption.
4Use of energy by stationary object
If the cooled environment volume is reduced, then energy consumption is reduced, but manufacturing precision is required to ensure airtight sealing
Solution Approach 1:
The airtight enclosures utilize flexible sealing elements such as rubber gaskets, foam seals, and flexible membranes at door frames and joint connections. These flexible materials accommodate minor dimensional variations and installation tolerances while maintaining effective airtight sealing, reducing the need for extremely tight manufacturing precision.

This approach significantly reduces energy consumption for cooling, enhances cooling efficiency, and prevents thermal failures by ensuring that the coldest air is delivered in high volumes directly to heat-producing components, allowing for the operation of modern electronic equipment without the need for extensive infrastructure upgrades or relocation of equipment.
Implementation Method 1
generating a pressure differential from a first side of the electronic equipment to a second side of the electronic equipment to create a flow of the cooling air

AI summary
A system and method of reducing consumption of electricity used to cool electronic computer data center, networking, and telecommunications equipment, and to reduce the incidence of thermal failure of electronic components, includes provision 5 of one or more partitions to reduce the volume of the cooled environment supplying coldest possible cooled air from air conditioning systems to a chamber adjacent to racks containing the electronic components, preventing dilution of the supplied cooling airflow by warmer air from outside of the reduced volume environment, and controlling the delivery of cooling air flow through the reduced volume of the cooled environment.
