Advantages and disadvantages of zipper fin heat sink


The main advantages of zipper fin heat sinks are: ‌

Efficient cooling and better performance: ‌ By using thin fins and high fin density ‌ zipper fin heat sinks enable a larger heat sink surface area and higher heat transfer efficiency ‌ thus providing more efficient cooling and better performance. ‌

Reduced mold costs: ‌ Unlike extrusion heat sinks, ‌ turning fin heat sinks do not rely on tools and multiple steps, ‌ instead uses a cutting tool, ‌ thereby reducing tool costs, ‌ increasing design flexibility and speeding up prototyping. ‌

Economy: ‌ zipper fin heat sinks are quickly manufactured, ‌ cost-effective and scalable, ‌ making them ideal for low to medium power applications. ‌

Less footprint: ‌ for applications where space is limited, ‌ by supporting more and longer fins and additional customization, ‌ adhesive heat sinks provide higher performance and greater surface area in a smaller footprint. ‌

However, ‌ zipper fin heat sinks also have some disadvantages: ‌

Not suitable for high power applications: ‌ due to its integrated structure reduces thermal resistance, ‌ but this structure is not suitable for high power applications, ‌ due to size limitations and large thermal resistance may not be effective heat dissipation. ‌

Size limitations: ‌ zipper fin heat sinks cannot be larger than approximately 23 inches wide and ‌47 inches long, ‌ which limits their use in some applications. ‌

Thinner fins may be more fragile: ‌ because of the thin fin design ‌ these fins may be relatively more fragile and ‌ not conducive to applications in high volume production environments. ‌

To sum up, ‌ zipper fin heat sink has its unique advantages in design and manufacture, ‌ such as efficient cooling, ‌ economy and small space occupation, ‌, but at the same time there are some limitations, ‌ is not suitable for high power applications and size limitations. ‌, therefore, ‌ in the choice of zipper fin heat sink, ‌ need to consider its advantages and disadvantages as well as the specific application needs. 

Liquid Cooling Technology: An Efficient New Cooling Solution for Coping with the Surge in Computing Power

  Concepts like 'AIGC in the field of artificial intelligence,' 'ChatGPT,' 'data special zones,' 'Eastern data and Western computing,' and 'data centers' are some of the hottest topics right now. Behind the surge in computing power, processor power consumption is increasing. To maximize processor performance, higher cooling efficiency is necessary.   With the explosive growth of computing power, we see an increase in power density and energy consumption in data centers. Traditional air cooling can no longer meet the growing cooling demands, highlighting the importance of   liquid cooling technology . The high power density of AI servers   makes 'liquid cooling' a cost-effective and efficient temperature control method.   Liquid cooling technology refers to the use of liquid instead of air as a coolant to exchange heat with heat-generating components and dissipate that heat. It involves directly introducing a liquid cooling system into the...

Liquid Cooling Loop: The Perfect Combination of Efficient Heat Dissipation and Leak-Proof Technology

As a crucial solution for heat dissipation in modern electronic devices, the design and maintenance of the liquid cooling loop  are of paramount importance. While pursuing efficient heat dissipation, minimizing or preventing condensation and leaks has always been our primary focus. Condensation is one of the common issues in liquid cooling loops. When the coolant temperature is lower than the ambient temperature, condensation may form on the cooling surface, which can drip onto electronic devices causing corrosion or accumulate at the bottom of the system leading to malfunctions. To address this, we have adopted advanced insulating materials to maintain the circuit temperature above the ambient dew point, effectively preventing condensation. In the design of the liquid cooling loop, we have fully considered the risk of leaks. To ensure the stable operation of the system, we cleverly position the reservoir and liquid circuit beneath the electronic devices. Even if a leak occurs, it ...
