Solution Overview
Problem
Existing data center cooling solutions consume large amounts of power and water resources, and are inefficient in removing heat from computer servers and network equipment, leading to performance degradation and premature component malfunction.
Innovation Solution
The implementation of heat pipes as a data center cooling solution, which transfer heat away from electronic devices using principles of thermal conductivity, evaporative cooling, and phase transition, either by absorbing heat from ambient air and circulating coolant fluid or by transferring heat from air to liquid or air interfaces, thereby reducing the need for traditional mechanical air cooling and liquid cooling systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional mechanical air cooling and liquid cooling systems are used, then heat can be removed from data center devices, but large amounts of power and water resources are consumed
Solution Approach 1:
The patent replaces traditional mechanical cooling systems (fans, compressors, pumps) with a heat pipe-based passive cooling system. The heat pipe utilizes phase change and thermal conduction to transfer heat from data center devices to a heat sink, eliminating the need for high-power mechanical components while maintaining effective heat removal.
Solution Approach 2:
The heat pipe employs phase transition of the working fluid (evaporation at the hot end, condensation at the cold end) to efficiently transfer heat. This phase change mechanism provides high heat transfer coefficients without requiring external power input, directly addressing the contradiction between energy consumption and cooling effectiveness.
2Loss of substance
If traditional mechanical air cooling and liquid cooling systems are used, then heat can be removed from data center devices, but large amounts of water resources are consumed
Solution Approach 1:
The patent replaces water-intensive liquid cooling systems with a heat pipe-based system that uses phase change of a sealed working fluid. This eliminates the need for large volumes of circulating water while maintaining effective heat removal through the heat pipe's high heat transfer capability.
Solution Approach 2:
The heat pipe uses phase transition of a small amount of sealed working fluid to achieve continuous heat transfer. This phase change mechanism provides efficient cooling without requiring the large water flows needed by traditional liquid cooling systems, directly reducing water resource consumption.
3Reliability
If components are not cooled sufficiently, then energy consumption decreases, but performance degrades and components malfunction prematurely
Solution Approach 1:
The patent replaces high-power mechanical cooling systems with a passive heat pipe system that consumes minimal energy. The heat pipe automatically transfers heat from components to a heat sink using phase change and thermal conduction, providing sufficient cooling to maintain component reliability without the high energy consumption of traditional systems.
Solution Approach 2:
The heat pipe's phase change mechanism provides efficient heat transfer with minimal energy input. The evaporation and condensation processes occur naturally driven by temperature gradients, enabling effective component cooling that extends lifespan without requiring large amounts of energy.
