Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rack servers generate significant heat due to numerous thermal components, leading to reduced operational stability and increased energy consumption in cooling systems, particularly as existing cooling methods relying on refrigerants are inefficient and environmentally harmful.
Innovation Solution
A cooling system utilizing air jet elements to convert high-pressure air into low-temperature air, which is then used in a heat exchange assembly with fin sets to dissipate heat from rack servers, eliminating the need for refrigerants and reducing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If refrigerant-based cooling systems are used to lower rack server temperatures, then cooling effectiveness is improved, but environmental pollution and system complexity increase
Solution Approach 1:
The patent extracts and eliminates the refrigerant component from the cooling system, replacing it with an air-based cooling mechanism. The heat exchange assembly directly uses ambient air to cool the rack server, removing the harmful refrigerant substance entirely from the system while maintaining cooling functionality.
Solution Approach 2:
The patent introduces air as an intermediary substance to transfer heat from the rack server to the environment. The heat exchange assembly facilitates heat transfer between the server components and ambient air, using air as a clean, environmentally friendly mediator instead of refrigerants.
2Temperature
If multiple heat exchange processes are used to cool rack servers, then temperature control is improved, but power consumption increases
Solution Approach 1:
The patent implements a continuous heat exchange process where ambient air continuously flows through the heat exchange assembly, absorbing heat from the rack server in a single uninterrupted process. This eliminates the need for multiple discrete cooling stages and their associated energy consumption.
Solution Approach 2:
The system utilizes ambient air, which is freely available and requires no additional energy input to source or circulate. The natural convection and flow of ambient air through the heat exchange assembly provides self-service cooling, eliminating the need for energy-intensive refrigerant compression and multiple heat exchange cycles.
3Productivity
If inbuilt fans are used to draw tempered air into the enclosure, then heat dissipation is improved, but the temperature of the computer room rises and cooling efficiency decreases
Solution Approach 1:
The patent segments the cooling function from the general computer room environment by implementing a dedicated heat exchange assembly that interfaces directly with ambient air. This localized cooling approach extracts heat at the source (the rack server) without necessarily heating the entire computer room, as the heat is transferred to ambient air flowing through the heat exchange assembly rather than being rejected into the enclosed space.
