Description

I. Types of Heat Sinks and Enhanced Technologies

Type Characteristics Applications
Passive Heat Sink Fanless, relies on natural convection (aluminum fins) Low-power devices (routers, LED lights)
Active Heat Sink Uses fans for forced cooling (higher efficiency but consumes power) Computer CPUs, graphics cards
Heat Pipe Cooler Utilizes heat pipes for rapid heat transfer High-performance laptops, servers
Liquid Cooler Uses liquid circulation (quiet and efficient) Overclocked PCs, data centers
Phase Change Cooler Employs phase change materials (e.g., vapor chambers) Smartphones, 5G base stations

Enhancement Technologies:

  • Surface Treatment: Anodizing (improves emissivity), graphene coating (enhances thermal conductivity).

  • Structural Optimization: Fin density/shape design (e.g., vortex fins to increase turbulence).


2. Key Selection Parameters

  • Thermal Resistance (°C/W): Lower values indicate better cooling performance.

  • Material: Copper (faster heat transfer but costly) vs Aluminum (lightweight and cost-effective).

  • Air Pressure & Flow Rate (for active cooling): Fan performance must match cooling requirements.

Industry Trends:

  • Miniaturization: Ultra-thin heat sinks (for foldable smartphones).

  • Intelligent Control: Temperature-regulated fan speed adjustment.

  • Green Cooling: Fanless designs (reduce noise and power consumption).
