Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If electrical devices are arranged in the cabinet, then the cabinet can hold and operate electrical equipment, but heat accumulates inside the cabinet causing temperature rise that affects normal operation and shortens service lives
Solution Approach 1:
The cooling system is segmented into multiple independent components: front-door cooling assembly with water-cooling radiator, rear-door cooling assembly with water-cooling radiator, and air exhaust assembly with heat dissipation fans. Each segment handles specific heat dissipation tasks, allowing distributed heat management throughout the cabinet structure.
Solution Approach 2:
Water-cooling radiators serve as intermediary heat transfer media between the electrical devices and the external environment. The water circulation system absorbs heat from internal devices through heat conducting plates and dissipates it externally through water cooling pipes, mediating the heat transfer process efficiently.
2Temperature
If conventional cooling methods are used, then the structure remains simple, but heat dissipation efficiency is insufficient to maintain normal operating temperatures
Solution Approach 1:
The system merges multiple cooling mechanisms into a unified heat dissipation system: water-cooling radiators combine conduction (through heat conducting plates) and convection (through water cooling pipes), while heat dissipation fans provide forced convection. The front-door and rear-door cooling assemblies work together with the air exhaust assembly to create a comprehensive cooling solution.
Solution Approach 2:
The system employs hydraulic cooling through water-cooling radiators where water circulates through pipes to absorb and transport heat. The water circulation mechanism provides efficient heat transfer compared to air cooling alone, enabling better temperature control despite increased system complexity.
3Reliability
If heat dissipation components are added to the cabinet, then temperature control improves, but the cabinet structure becomes more complex and space is consumed
Solution Approach 1:
Cooling assemblies are positioned at specific locations: front-door cooling assembly at the front end, rear-door cooling assembly at the rear end, and air exhaust assembly between them. Each location receives targeted cooling based on heat generation patterns, providing localized heat dissipation where most needed while minimizing overall system complexity.

Function Achieved in This Case
Effectively lowers the temperature inside the cabinet by accelerating external air entry, conducting heat away through water-cooling radiators, and exhausting hot air, thereby improving device performance and extending service life.
Implementation Method 1
the water-cooling radiator comprises a water cooling plate, heat conducting plates, and water cooling pipes... the heat conducting plates and the water cooling pipes being both fixedly connected to the water cooling plate
Implementation Method 2
cold water at a relatively low temperature flows through an inlet into the water-cooling radiator to have the hot air of the server and the water-cooling radiator exchange heat
Implementation Method 3
the heat dissipation fan being fixedly connected to one side of the ventilation plate, the heat dissipation fan discharging heat inside the cabinet body through the airflow passage openings to outside
Implementation Method 4
the flow guide plate being formed with flow guide openings, the flow guide openings transferring heat inside the cabinet body to outside

AI summary
A data cabinet heat-dissipating system includes an air exhaust assembly, a flow guide plate, and a water-cooling radiator. The air exhaust assembly includes a ventilation plate and a heat dissipation fan. The flow guide plate includes a flow guide plate and flow guide openings. The water-cooling radiator includes a water cooling plate, heat conducting plates, and water cooling pipes. The flow guide plate accelerates entry of external air into the cabinet. A server in the cabinet generates heat and air flowing through the flow guide plate generates minute airflows that push the heat of the server to the water-cooling radiator, where cold water flows into the water-cooling radiator to cause heat exchange with the heat of the server and heat of the cabinet so subjected to heat exchange with the water-cooling radiator is conveyed to outside for cooling.
