Closed Cold Pool System for High-Power Transmission Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-power-consumption transmission devices in communication machine rooms face heat dissipation issues due to complex air ducts, which hinder the construction of a cold pool environment and lead to local hot spots and inefficient cooling.
Innovation Solution
A closed cold pool system is implemented, featuring a cabinet assembly with in-row air conditioners and air guide cabinets that change the air duct form from front-rear air-inlet to top air-outlet, creating isolated cold aisles for efficient air circulation and heat dissipation, decoupling the heat dissipation of transmission devices from the overall machine room environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex air duct form is used in transmission devices, then ventilation functionality is achieved, but cold pool construction becomes impossible due to air mixing
Solution Approach 1:
The patent divides the transmission device into separate functional modules: a cold pool construction module with simplified air ducts and a ventilation function module with complex air ducts. This segmentation allows each module to be optimized independently - the cold pool module achieves proper cold air circulation while the ventilation module handles air intake and exhaust functions.
Solution Approach 2:
The patent introduces an intermediary cold pool construction module that acts as a mediator between the ventilation function module and the transmission devices. This intermediate structure receives cold air from the simplified air ducts and delivers it to the transmission devices, enabling cold pool formation without requiring the transmission devices themselves to have complex air ducts.
2Productivity
If high-power-consumption transmission devices are deployed, then communication capacity increases, but local hot spots occur due to insufficient cooling
Solution Approach 1:
The patent implements local quality by creating a dedicated cold pool environment specifically for high-power-consumption transmission devices. The cold pool construction module provides localized cooling with simplified air ducts that deliver cold air directly to these devices, while the surrounding area maintains normal temperature conditions.
3Loss of energy
If traditional cooling methods are used for high-power-consumption devices, then heat dissipation is achieved, but cold pool environment cannot be formed
Solution Approach 1:
The patent segments the cooling system into two parts: a cold pool construction module with simplified air ducts that form the cold environment, and a ventilation function module with complex air ducts that handle heat dissipation. This segmentation allows the simplified ducts to create the cold pool while the complex ducts manage the ventilation and heat removal functions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively addresses heat dissipation challenges by creating a micro-cold pool structure that improves local refrigeration efficiency and reduces maintenance costs by isolating heat dissipation, minimizing the impact of high-power-consumption devices on the machine room environment.
Implementation Method 1
The hot air enters the air return opening of the air conditioner and is cooled by a coil
Implementation Method 2
An air duct form of the transmission devices is changed to a form of front-rear air-inlet and top air-outlet by the air guide cabinets mounted on the left and right sides of the transmission devices
Implementation Method 3
After the cold air enters the main device unit, hot air is discharged into the external environment at the top of the micro-cold pool by the devices themselves and the air guide cabinets on both sides. The hot air enters the air return opening of the air conditioner and is cooled by a coil, and is then conveyed to the front and rear cold aisles via the front and rear air supply openings, thereby forming a complete air circulation
