China Lightweight Heat Sink for Small-Size Electronic Components Supplier, Suppliers

Our high-efficiency heat sink, made of premium aluminum-copper composite, boasts excellent thermal conductivity to rapidly dissipate heat for electronics. It offers both passive (fan-free) and active (120mm quiet fan) options, fitting scenarios like desktop PC CPUs/GPUs, industrial inverters, and LED lighting fixtures. With a compact, lightweight design, it saves space, while its high-temperature resistance ensures long-lasting durability. Ideal for PC builders, industrial equipment manufacturers, and LED suppliers, this heat sink balances strong cooling performance, quiet operation, and reliability to meet diverse cooling needs.

Product Description

Advantages

1. Efficient Heat Dissipation

Made of high thermal-conductivity materials (aluminum: ≥200 W/m·K; copper: ≥400 W/m·K), they quickly transfer heat from components. Passive models handle 30–65W loads and active ones support ≥100W with low thermal resistance (down to 0.3 K/W).

2. High Reliability & Long Life

Passive heat sinks have no moving parts (service life ≥10 years). Active models use durable PWM fans (MTBF ≥50,000 hours) and tolerate extreme conditions (-40°C to +125°C) without performance drops.

3. Low Noise

Passive designs produce 0 dB noise. Active ones adjust fan speed via PWM: 30–40 dBA at low loads and only ramp up when needed.

4. Cost-Effectiveness

Aluminum extrusion and copper-aluminum composites cut material costs. Long-term TCO is 30–50% lower than liquid cooling over 5 years due to no maintenance needs.

5. Flexible Installation

Sizes from 50×50×15mm to 300×200×80mm. Compatible with screws, adhesive, or standard sockets (e.g., Intel LGA1700).

6. Eco-Friendliness

95-100% recyclable materials. Meets RoHS/REACH standards with low CO₂ emissions during production.

Application

Simplified Applications of Heat Sink Devices

Heat sinks are widely used to cool heat-generating components across various industries, preventing overheating-related performance issues.

1. Consumer Electronics

Needs: Small size, low noise, and fit for compact spaces.

PCs & Laptops: Passive aluminum heat sinks for low-power CPUs (35–65W). Active heat sinks for high-performance GPUs (100–150W). Laptops use ultra-slim designs (≤15mm).
Gaming Consoles & Smart Devices: Consoles like PS5 use large aluminum sinks + fans for 150–200W APUs. Phones utilize tiny copper sinks or graphite sheets for high-power SoCs.

2. Industrial Control

Needs: Durability in harsh conditions and long-term reliability.

Industrial Controllers (PLCs/DCS): Passive aluminum-copper heat sinks cool power modules like IGBTs. No moving parts reduce maintenance, and corrosion-resistant coatings protect against dust.

Frequently Asked Questions

Q1: What materials are primarily used in your heat sinks?

Our heat sinks are primarily made from high thermal-conductivity aluminum (≥200 W/m·K) and copper (≥400 W/m·K) to ensure rapid heat transfer.

Q2: What is the expected service life of a passive heat sink?

Passive heat sinks have no moving parts, resulting in an exceptionally long service life, typically exceeding 10 years with minimal maintenance.

Q3: Are active heat sinks loud?

Active models use PWM-controlled fans that only increase speed when needed. They operate at a quiet 30–40 dBA under low loads.

Q4: Can these heat sinks withstand extreme temperatures?

Yes, our industrial-grade models are designed to operate reliably in environments ranging from -40°C to +125°C.

Q5: How do heat sinks compare to liquid cooling in terms of cost?

Heat sinks offer a much lower Total Cost of Ownership (TCO), typically 30–50% cheaper than liquid cooling over 5 years due to lower material costs and zero coolant refills.

Q6: Are the materials used in the heat sinks recyclable?

Yes, the aluminum is up to 95% recyclable and the copper is 100% recyclable, and our products fully meet RoHS/REACH standards.
