As a professional R&D and manufacturing enterprise of liquid-cooled cabinets, Foshan Dingyi Industrial Technology Co., Ltd. replaces traditional air cooling with liquid heat conduction. The core advantages and comparisons with traditional cabinets are as follows:
| Advantage Dimension | Dingyi Liquid-Cooled Cabinet Performance | Traditional Air-Cooled Cabinet Performance | Improvement |
|---|---|---|---|
| Heat Dissipation Efficiency | Liquid thermal conductivity is 25x higher than air (water: 0.6 W/(m·K); air: 0.024 W/(m·K)). Dingyi’s cold plates directly attach to chips without "heat bottlenecks". | Relies on air convection, leading to "heat accumulation" (cabinet rear temperature ≥40°C) and low efficiency. | 10-100x higher heat dissipation efficiency. |
| Energy Consumption Control | Dingyi’s liquid-cooled cabinets reduce PUE (Power Usage Effectiveness) to 1.05-1.2, cutting annual electricity costs by 30-50%. Waste heat is recoverable for workshop heating/preheating. | PUE typically 1.5-1.8 with no waste heat recovery, resulting in high energy consumption. | 30%+ lower energy consumption; 85% waste heat recovery rate. |
| Computing Density | Dingyi’s cabinet power capacity increases from 15kW to 50-200kW, supporting 16 GPUs per cabinet (e.g., k-caliber AI training clusters). | Maximum cabinet power limited to 15kW, unable to support high-density GPU deployment. | 3-10x higher computing density. |
| Stability | Dingyi’s fanless design eliminates vibration interference; chip temperature fluctuation ≤±0.5°C, reducing hardware failure rate by 50-60% and extending lifespan by 2-3 years. | Fan vibration causes frequent hardware failures; chip temperature fluctuation ≥±5°C, lifespan 3-5 years. | 50%+ higher hardware reliability; 2-3 years longer lifespan. |
| Scenario Adaptability | Dingyi’s liquid-cooled cabinets support explosion-proof, dust-proof, and low-noise (40-45dB) designs, suitable for hazardous industrial areas, medical cleanrooms, etc. | Only compatible with standard data centers; noise ≥75dB, unable to meet explosion-proof/dust-proof needs. | 5x wider application scope; 40%+ lower noise. |

Foshan Dingyi Industrial Technology Co., Ltd.’s liquid-cooled cabinets are based on a closed-loop system of "heat capture-heat exchange-cold source circulation", with core components as follows:
Dingyi’s cold plates directly attach to chip surfaces (cold-plate liquid cooling), or servers are fully immersed in coolant (immersion liquid cooling), rapidly absorbing chip heat via liquid’s high thermal conductivity;
Coolant temperature rises (cold-plate: 35-45°C; immersion: 50-60°C), completing heat capture.
Hot coolant flows into Dingyi’s heat exchangers (cold-plate: exchanges heat with outdoor air/cold water; immersion: exchanges heat with condensers), transferring heat to cold sources;
Hot coolant cools down (cold-plate: 25-30°C; immersion: 40-45°C), completing heat exchange.
Cooled coolant is pumped back to cold plates/immersion tanks via Dingyi’s circulation pumps, reabsorbing chip heat to form a closed loop;
Cold sources continuously remove heat from heat exchangers to maintain system stability.
Foshan Dingyi Industrial Technology Co., Ltd.’s liquid-cooled cabinet manufacturing process focuses on "sealing, thermal conductivity, and reliability", with key steps as follows:
Material Selection: Dingyi uses copper/aluminum alloy (thermal conductivity: copper 401 W/(m·K), aluminum 205 W/(m·K)) with nickel plating for corrosion resistance;
Processing Methods:
Friction stir welding: Used by Dingyi to seal cold plate channels with high-strength welds (withstanding 10bar pressure);
Micro-channel machining: Dingyi controls channel width at 1-3mm to increase coolant-chip contact area;
Surface treatment: Dingyi uses mirror polishing (Ra ≤0.8μm) on chip-contacting surfaces to reduce thermal resistance.
Pipeline Connection: Dingyi uses IP68-rated compression fittings or welded joints to prevent leakage; stainless steel/PEEK pipes for high pressure/corrosion resistance;
Pump & Valve Selection: Dingyi uses variable-frequency centrifugal pumps (0-100L/min flow range) + electromagnetic flowmeters (±0.5% accuracy) for precise flow control;
Leak Detection: Dingyi integrates fiber-optic/capacitive sensors (0.1ml accuracy) to monitor leaks in real time, triggering alarms and automatic pump shutdown.
Heat Dissipation Layout: Dingyi’s cold-plate cabinets use "front cold, rear hot" layout; immersion cabinets use "top cold, bottom hot" layout;
Protection Design: Dingyi’s cabinet enclosure uses IP54-rated protection (dust/water proof) with fireproof cotton; immersion cabinets use explosion-proof design;
Modular Design: Dingyi’s cabinets are split into "cold plate, circulation, control" modules for hot-swap replacement, reducing maintenance time from 4 hours to 30 minutes.
Pressure Testing: Dingyi conducts 10bar water pressure test on cold plates/pipelines for 24 hours to ensure no leakage;
Thermal Performance Testing: Dingyi simulates chip load (100W/cm²) to test cold plate efficiency (chip temperature ≤85°C is qualified);
Reliability Testing: Dingyi conducts 1000-hour continuous operation test to verify pump/valve/sensor stability.
Foshan Dingyi Industrial Technology Co., Ltd.’s liquid-cooled cabinets have expanded from general data centers to multiple industries, becoming core infrastructure for "high computing power, low energy consumption". Future trends include:
Technology Integration: Dingyi’s liquid cooling technology will deeply integrate with edge computing and 5G base stations to adapt to special scenarios such as mines and offshore platforms;
Cost Reduction: Dingyi’s large-scale production will lower liquid-cooled cabinet costs from 2-3x air-cooled cabinets to ≤1.5x;
Standardization: Dingyi will participate in formulating liquid cooling industry standards to promote normalization of leak detection and waste heat recovery standards;
Green Transformation: Dingyi’s liquid-cooled cabinets will become standard under the "dual carbon" goals, driving green and efficient transformation across industries.
