Solution Overview
Problem
Datacenter cooling systems face challenges in providing redundant and efficient cooling solutions, particularly in addressing sudden high heat requirements and failures in primary cooling loops, which can lead to inadequate heat management and downtime.
Innovation Solution
An intelligent and redundant air-cooled cooling loop system is introduced, featuring a primary cooling loop supported by a secondary loop with a liquid-to-air heat exchanger and a fluid source, enabling alternate coolant circulation to maintain cooling even in primary loop failures, using a dual-cooling cold plate and flow controllers to manage coolant flow.

1Use of energy by moving object
If a primary cooling loop is used for datacenter cooling, then cooling efficiency is improved, but system reliability deteriorates due to lack of redundancy
Solution Approach 1:
The cooling system is divided into two independent loops: a primary cooling loop and a secondary cooling loop. Each loop has its own coolant circulation path, heat exchangers, and control mechanisms. This segmentation allows the system to maintain cooling functionality even when one loop fails, thus improving reliability while maintaining cooling efficiency through the primary loop.
Solution Approach 2:
The secondary cooling loop is prepared in advance as a standby system with all necessary cooling components pre-installed and configured. When the primary loop fails, the secondary loop can immediately activate to provide cooling coverage, cushioning against the harmful effect of complete cooling system failure and ensuring continuous operation.
2Reliability
If a redundant cooling loop is added, then system reliability is improved, but device complexity increases
Solution Approach 1:
The secondary cooling loop is designed with universal components that can serve both as a standby system and as an active cooling system. The same heat exchangers, coolant channels, and control mechanisms are used in both loops, reducing the need for entirely separate redundant components and thereby limiting the increase in device complexity.
Solution Approach 2:
The primary and secondary cooling loops share common infrastructure elements such as the coolant reservoir, pump housing, and control system architecture. By merging these common elements, the system achieves redundancy while minimizing the additional complexity that would result from completely separate systems.
3Reliability
If coolant flow is redirected to secondary loop, then redundancy is activated, but cooling efficiency may deteriorate
Solution Approach 1:
The system employs dynamic flow control mechanisms that can adjust coolant distribution between the primary and secondary loops in real-time. When the primary loop is operational, the majority of coolant flow is directed through it for optimal efficiency. When the primary loop fails, the flow control dynamically redirects coolant to the secondary loop, maintaining adequate cooling performance while activating redundancy.
Solution Approach 2:
The control system continuously monitors the operational status of the primary cooling loop and provides feedback to the flow control mechanisms. Based on this feedback, the system automatically adjusts coolant flow distribution to maintain optimal cooling efficiency during normal operation and ensures adequate cooling performance when redundancy is activated.
