Introduction: Why Heat Sinks Keep Things Cool
The Magic of Staying Cool
Imagine your phone getting super hot while playing a game. It might slow down or even stop working. That’s where heat sinks come in—they’re like cool towels for electronics, soaking up heat to keep devices happy. Heat sinks are metal pieces that pull heat away from things like computers, LED lights, and big machines, so they run smoothly without overheating.

Using the Table
This table gives you a snapshot of heat sink types and how KenFa Tech makes them special. Whether you need a fan-powered cooler or a liquid cooling solution, they’ve got you covered. Let’s dive into what heat sinks are all about next.
What Are Heat Sinks and How Do They Work?
Heat Sinks 101
Heat sinks are metal pieces that grab heat from hot electronics, like your computer’s brain (the CPU) or a bright LED light. They’re like sponges that soak up heat, then let it escape into the air or water. This keeps your devices from getting too hot and breaking down.
The Cooling Process
Here’s how they work in three easy steps:
- Heat moves: The hot device sends heat to the heat sink’s flat base.
- Heat spreads: Fins or tubes in the heat sink spread the heat out.
- Heat escapes: Air or water flows over the fins, carrying heat away.
KenFa Tech uses tools like Ansys Icpak to design heat sinks that work perfectly for each job. Their heat pipe assemblies add extra cooling power for tough tasks.
Why Heat Sinks Matter
Without heat sinks, your phone might shut off during a game, or a server could crash during a big task. They’re in tons of tech, from LED lighting to electric vehicle batteries. “Heat sinks are the backbone of modern electronics,” says Dr. Jane Smith, a thermal management expert. “KenFa Tech’s designs push the limits of what’s possible.”
KenFa Tech’s Edge
We doesn’t just build heat sinks—they make them smarter. Their thermal analysis ensures every design, like aluminum VC heat sinks, is built to last. It’s all about keeping your tech cool and reliable.
Heat Sink Types by Airflow
Active Cooling: Fans in Action
Active heat sinks use fans to blow air over their fins, pushing heat away quickly. They’re like a breeze cooling you down on a hot day. These are perfect for powerful devices like gaming PCs or cloud computing servers. For example, KenFa Tech’s skived fin heat sinks with fans can handle up to 1200W of heat, like their KF-HS-20-SK009 model.
Passive Cooling: Quiet and Simple
Passive heat sinks don’t need fans—they let air move naturally over their fins. This makes them super quiet, ideal for devices like LED lights or small gadgets where noise is a no-go. KenFa Tech’s cold-forged heat sinks, like their 104W design, shine here, offering strong cooling without a sound.
Our Airflow Expertise
KenFa Tech nails both active and passive cooling. Their fan-based designs are ready in just 24 hours, perfect for fast projects. For passive needs, their die-cast heat sinks are tough and silent. Whether it’s a noisy fan or a calm fin, they’ve got the right solution.
Which Airflow Type Suits You?
Choose active cooling for high-power tech that needs fast heat removal. Go passive for quiet, low-power devices. KenFa Tech’s team, with roots at companies like AAVID, crafts both with precision, ensuring your device stays cool. Their testing processes guarantee every heat sink performs as promised.
Heat Sink Types by Material
Aluminum: Light and Affordable
Aluminum heat sinks are like the all-purpose players of cooling. They’re lightweight, cheap, and great for everyday devices like phones or laptops. KenFa Tech’s aluminum VC heat sinks and skived fin designs cool up to 600W, like for LED lighting, with finishes like powder coating for extra durability.
Copper: The Heat-Moving Champ
Copper heat sinks are heavier and pricier but move heat better than aluminum. They’re ideal for big systems like servers or IGBT modules. KenFa Tech’s copper tube liquid cold plates are built for high-performance cooling, handling tough heat loads with ease.
KenFa Tech’s Material Mastery
We know how to pick the right material. Their aluminum designs, like those for LEDs, save money without sacrificing quality. For heavy-duty needs, their copper solutions, backed by brazing expertise, deliver top results. “Material choice is key to cooling success,” says Dr. Smith. “KenFa Tech’s precision makes all the difference.”
Choosing the Right Material
Go with aluminum for budget-friendly, lightweight cooling. Choose copper for maximum heat transfer in big systems. KenFa Tech’s quality control ensures both materials perform reliably, tailored to your project’s needs.
Heat Sink Types by Use of Water
Solid Metal Heat Sinks: Air Only
Solid metal heat sinks rely on air to cool, no water needed. They’re simple and great for smaller devices like chips or LEDs. KenFa Tech’s skived fin heat sinks, like their 4100W IGBT design, handle massive heat with just air, making them versatile and cost-effective.
Pumped Liquid Heat Sinks: Water Power
Pumped liquid heat sinks use water to cool big machines, like data centers or solar inverters. Water flows through tubes, pulling heat away fast. KenFa Tech’s liquid cold plates with 2-6 pass tunnels are built to handle heavy loads, with leak-proof designs for safety.
Two-Phase Heat Sinks: Liquid to Gas
Two-phase heat sinks are high-tech—they use liquid that turns to gas to cool super-hot systems, like advanced servers. KenFa Tech’s custom cooling solutions include two-phase designs for cutting-edge tech, offering top performance for extreme heat.
Our Water-Based Expertise
KenFa Tech excels in all three types. Their solid metal sinks, like high-power skived fins, are perfect for air cooling. Their pumped liquid plates, tested via rigorous validation, tackle big systems. For two-phase, their tailored designs push boundaries, ensuring your tech stays cool.
Heat Sink Types by Manufacturing Process
CNC Machined Heat Sinks: Precision Cuts
CNC machined heat sinks are made with machines that cut metal super precisely. They’re perfect for custom, high-tech devices needing exact shapes. KenFa Tech’s CNC machined parts offer spot-on designs for unique cooling needs, ensuring every detail is perfect.
Forged & Die Cast Heat Sinks: Tough and Quiet
Forged and die-cast heat sinks are pressed or molded into strong shapes, great for quiet, passive cooling. KenFa Tech’s cold-forged heat sinks, like their 104W design, are ideal for devices that need silent, reliable cooling.
Zipper Fin Heat Sinks: Stacked Cooling
Zipper fin heat sinks stack fins like a zipper, giving more surface area for cooling. They’re good for medium-power systems. KenFa Tech’s bonded fin expertise ensures these designs are flexible and effective.
Skived Fin Heat Sinks: Thin and Powerful
Skived fin heat sinks have thin fins cut from metal, perfect for hot chips like IGBTs. KenFa Tech’s skived fin designs, like their 4100W IGBT solution, can be huge—up to 2000x700x130mm!
Bonded Fin Heat Sinks: Glued Strength
Bonded fin heat sinks glue or solder fins for extra cooling area, ideal for medium-power devices. KenFa Tech’s soldering skills make these heat sinks super durable.
Extruded Heat Sinks: Affordable Shapes
Extruded heat sinks are molded like Play-Doh, making them cheap and great for everyday electronics. KenFa Tech’s extruded heat sinks are ready in just 3 weeks, perfect for quick projects.
How to Choose the Right Heat Sink Type
Key Factors to Think About
Picking the right heat sink can feel tricky, but it’s simple if you know what to look for. Here are four things to consider:
