Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current containerized data systems face issues with independent ventilation ducts leading to decreased heat dissipation performance when one air-conditioning unit fails, causing localized temperature increases due to inadequate mutual assistance among air-conditioning equipment.
Innovation Solution
A containerized data system design that integrates a first and second cabinet array with separate cold and hot aisle connection spaces, utilizing multiple air-conditioning devices outside the container body to facilitate air exchange, enhancing mutual takeover performance and improving heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If multiple air-conditioning devices are equipped in the containerized data system, then the cooling capacity is improved, but the ventilation ducts are independent and cannot assist each other when one fails, causing localized temperature increases
Solution Approach 1:
The patent merges the ventilation duct systems of multiple air-conditioning devices into a shared network. The ducts are interconnected such that cold air from any operating air-conditioning device can be distributed to multiple cabinet arrays, and hot air from any device can be vented through any available duct path. This integration enables automatic mutual assistance when one air-conditioning device fails, eliminating localized temperature increases while maintaining improved cooling capacity.
2Device complexity
If independent ventilation ducts are used for each air-conditioning device, then the system structure is simplified, but the heat dissipation performance decreases when one air-conditioning unit fails
Solution Approach 1:
The patent designs the ventilation duct system with universal functionality where each duct serves multiple purposes and can be used by any air-conditioning device. The duct network is configured so that any duct can function as either a cold air supply channel or a hot air exhaust channel depending on which air-conditioning devices are operational. This multi-functional design maintains structural simplicity while ensuring that heat dissipation performance is preserved even when one air-conditioning unit fails, as other devices can utilize the same duct infrastructure.

Function Achieved in This Case
The system effectively prevents localized temperature rises by ensuring mutual assistance among air-conditioning units, maintaining optimal operating conditions and enhancing heat dissipation performance.
Implementation Method 1
a plurality of first air-conditioning devices arranged outside the container body, each first air-conditioning device defining an air inlet communicating with the hot aisle connection space to collect the hot air flow in the container body, and an air outlet communicating with the cold aisle connection space to convey the cold air flow to the container body
Data Source
AI summary
A containerized data system, including a container body, a first cabinet array, a second cabinet array and a plurality of first air-conditioning devices. The first cabinet array and the second cabinet array are positioned in the container body and spaced apart from each other. Air intake areas of the first cabinet array and the second cabinet array communicates with a cold aisle connection space of the container body. Heat dissipation areas of the first cabinet array and the second cabinet array communicate with a hot aisle connection space of the container body. Air inlets of the first air-conditioning devices are communicated with the hot aisle connection space to collect the hot air flow in the container body, and air outlets of the plurality of first air-conditioning devices are communicated with the cold aisle connection space to convey the cold air flow to the container body.
