Technical details and manufacturing context for Cooling System (Fan & Heat Sinks)

Definition
A critical component of Power Source Units that actively removes heat generated during power conversion and regulation processes. It combines forced air convection (via fans) with passive heat dissipation (via heat sinks) to prevent overheating, ensure electrical efficiency, and extend the lifespan of sensitive electronic components within the unit.
Working Principle
Heat generated by power electronics is conducted to metal heat sinks, which increase surface area for heat dissipation. Fans create airflow across the heat sinks, accelerating heat transfer to the surrounding environment through convection, thereby maintaining safe operating temperatures.
Common Materials
Aluminum alloy, Copper, Plastic polymers
Technical Parameters
  • Airflow capacity of the cooling fan (CFM) Per Request
Components / BOM
  • Axial Fan
    Generates directed airflow across heat sinks
    Material: Plastic housing with metal blades
  • Aluminum Heat Sink
    Passive heat dissipation through extended surface area
    Material: Aluminum alloy
  • Thermal Interface Material
    Improves heat conduction between components and heat sink
    Material: Thermal paste or pad
Engineering Reasoning
0-5000 RPM, 20-80°C ambient temperature, 0.5-2.0 m³/min airflow
Bearing seizure at 5500 RPM, motor winding insulation breakdown at 150°C, fan blade resonance at 5200-5400 RPM
Design Rationale: Lubricant thermal degradation (Arrhenius equation: k=Ae^(-Ea/RT)), electromagnetic force-induced bearing wear (Lorentz force: F=qv×B), aerodynamic flutter at critical Reynolds number (Re>2×10⁵)
Risk Mitigation (FMEA)
Trigger Electrolytic capacitor ESR increase to 0.5Ω at 105°C (Arrhenius acceleration factor α=2 per 10°C rise)
Mode: PWM controller voltage ripple exceeding 200mVpp causing motor phase current imbalance
Strategy: Polymer aluminum capacitors with 5000h MTBF at 125°C, coupled with NTC thermistor feedback loop (β=3950K)
Trigger Dust accumulation exceeding 15g/m² on heat sink fins reducing thermal conductivity from 205 to 40 W/m·K
Mode: Junction temperature delta-T exceeding 65°C (Tj=Ta+Rθja×Pdiss)
Strategy: Hydrophobic nanocoatings with 110° contact angle, combined with piezoelectric self-cleaning at 32kHz resonance

  • Available space/volume constraints (mm³)
  • Maximum allowable component temperature (°C)

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Bearing degradation
Cause: Lubrication failure due to grease breakdown, contamination, or inadequate relubrication intervals leading to increased friction, wear, and eventual seizure or catastrophic failure.
Fan blade imbalance or fatigue cracking
Cause: Material fatigue from cyclic stresses, foreign object damage (FOD), or accumulation of debris/dirt altering aerodynamic balance, resulting in excessive vibration and potential blade separation.
Maintenance Indicators
  • Abnormal or increasing vibration levels accompanied by unusual audible humming, grinding, or rumbling noises from the fan assembly.
  • Visible accumulation of debris on heat sink fins or fan blades, or observable physical damage such as bent blades, cracks, or corrosion on components.
Engineering Tips
  • Implement a proactive lubrication management program with condition-based intervals using high-temperature grease, proper purging techniques, and monitoring of bearing temperature and vibration trends.
  • Establish regular cleaning schedules for heat sinks and fan blades using non-abrasive methods, and conduct periodic infrared thermography to detect overheating spots indicating airflow restriction or fouling.

Manufacturing Precision
  • Heat sink base flatness: ≤0.1mm per 100mm length
  • Fan blade balance tolerance: ≤ISO G6.3 grade at operating speed
Quality Inspection
  • Thermal performance verification test (heat dissipation capacity measurement)
  • Vibration analysis test (to detect imbalance and bearing defects)
