Rear-Mounted Computer Bay Cooling Device for High-Density Data Centers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computer room cooling solutions are inefficient due to the need for significant empty space to accommodate cooling means, leading to low economic efficiency in floor space, cabling, and power consumption, and require costly modifications or replacements when equipment heat dissipation needs change.
Innovation Solution
A removable and interchangeable cooling device with an air/water heat exchanger positioned at the rear of the computer bay, using a supporting frame that allows for easy installation and maintenance without altering the bay's structure, and includes flexible piping and fan systems for efficient heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air conditioning is used to cool the entire computer room, then all computer equipment can be cooled, but the floor space efficiency is low and power consumption is high
Solution Approach 1:
The patent implements localized cooling by installing cooling devices directly at the rear of individual computer bays rather than cooling the entire room. Each cooling device handles only the heat dissipation from its specific bay, creating locally optimized thermal management that reduces overall energy consumption while maintaining effective temperature control where needed.
Solution Approach 2:
The cooling function is extracted from the centralized air conditioning system and assigned to individual bay-level cooling devices. This extraction allows each bay to be cooled independently by dedicated equipment, eliminating the energy waste of cooling empty spaces and improving overall system efficiency.
2Temperature
If cooling means are integrated into the bay structure, then cooling efficiency improves, but the bay structure becomes more complex and harder to maintain
Solution Approach 1:
The cooling system is segmented into independent, modular units that can be attached to or removed from individual bays. Each cooling device operates as a separate module with its own cooling means, allowing for easy installation, maintenance, and replacement without affecting the overall bay structure or other cooling units.
Solution Approach 2:
The cooling devices are designed to be dynamically configurable - they can be installed on specific bays based on cooling needs and removed or relocated when requirements change. This dynamic approach allows the system to adapt to varying heat dissipation demands without permanent structural modifications.
3Ease of manufacture
If standard computer racks are used with fixed depth, then manufacturing is simple, but the ability to accommodate cooling means and maintain maintenance access is limited
Solution Approach 1:
The cooling device acts as an intermediary component that interfaces between the standard bay structure and the cooling function. By positioning the cooling means at the rear of the bay and using flexible piping connections, the system accommodates cooling requirements without modifying the standard rack dimensions or compromising maintenance access to the false floor.
