Solution Overview
Problem
Datacenter cooling systems face challenges in efficiently managing sudden high heat requirements due to changing computing loads, particularly in high heat density areas with components like GPUs, CPUs, and switches, where existing cooling methods may not provide adequate thermal equilibrium or redundancy.
Innovation Solution
A datacenter liquid cooling system with a rack form-factor fluid reservoir that uses a primary-to-secondary cooling loops architecture, incorporating a tank with fluid that can be cooled by a secondary coolant or an air-cooling system, providing redundancy and thermal equilibrium by supplying cooling fluid to cold plates or immersion-cooled servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a primary cooling loop is used to cool high heat density components, then cooling efficiency is improved, but system reliability deteriorates due to lack of redundancy
Solution Approach 1:
The patent implements a reservoir containing cooling fluid that can serve as a backup cooling source before cooling failure occurs. The reservoir is pre-filled with adequate cooling fluid volume to sustain cooling operations during primary loop failures, providing beforehand cushioning against cooling system failures and ensuring continuous thermal management of high heat density components.
Solution Approach 2:
The patent introduces a secondary cooling loop with a reservoir as an intermediary cooling system between the primary cooling loop and the high heat density components. When the primary loop fails, the secondary loop with the reservoir acts as a mediator to maintain cooling operations, allowing smooth transition and ensuring system reliability without compromising cooling efficiency.
2Reliability
If cooling fluid volume is increased to provide redundancy, then system reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements a nested cooling system architecture where the secondary cooling loop with the reservoir is integrated within or alongside the primary cooling loop infrastructure. The reservoir is positioned to utilize existing space in the datacenter cooling system, and the secondary loop shares common components such as piping and heat exchangers with the primary loop, reducing overall system complexity while maintaining cooling redundancy.
3Stability of the object's composition
If thermal equilibrium is maintained through additional cooling loops, then temperature stability is improved, but energy consumption increases
Solution Approach 1:
The patent implements a dynamic cooling system where the secondary cooling loop with the reservoir is activated only when the primary cooling loop experiences failures or when additional cooling capacity is required. The system dynamically transitions between single-loop and dual-loop operation modes, maintaining thermal equilibrium through intelligent control that adjusts cooling loop activation based on real-time thermal conditions and load requirements, thereby avoiding continuous energy consumption of the secondary loop during normal operation.
