Do Zipper Fin Heat Sinks Need to be Tooled and is there an NRE?

A common question we get asked is: “Do Zipper Fin Heat Sinks Need to be Tooled and is there an NRE?” The short answer is yes. The individual fins that are used to create Zipper Fin heat sinks have to be created, and that does require a tool to create them. But is there an NRE (non-recurring engineering charge) to do that?

Well if the Zipper Fin heat sinks are from ATS, the answer is NO. The ATS selection of pre-tooled zipper fin profiles provides reliable cooling at significant cost savings for customers. Zipper fin heat sinks are a cost-effective and lightweight alternative to other high fin density solutions, especially for high-volume production. ATS pre-tooled zipper fin profiles have no NRE (non-recurring engineering charge) to offer further savings for customers!

Free engineering webinar “Battery Cooling in Automotive and the Electrification of Transportation” Tuesday 11-12-20 2PM EST

Advanced Thermal Solutions, Inc. (ATS) has announced the next webinar in their 2020-2021 series, “Battery Cooling in Automotive and the Electrification of Transportation”. The webinar is on November 12, 2020, at 2 PM EST.

Batteries play a key role in the electrification of transportation, whether it’s a car, a truck, a scooter, or any battery-powered vehicle. As electrochemical devices, battery performance, safety, and life depend on temperature. At high temperatures, although performance improves, batteries degrade faster and safety becomes a concern. At low temperatures, the battery capacity and resistance increase leading to lower energy and power capabilities. Therefore, thermal management of the battery pack becomes very important to achieve the intended performance and durability. This webinar will address the theory of this thermal management of batteries and their charging, and specific strategies that can be used.

Our speaker is Dr. Kaveh Azar, Ph.D.  is the president, CEO and founder of Advanced Thermal Solutions, Inc. (ATS), a leading engineering and manufacturing company focused on the thermal management of electronics. Dr. Azar holds 36 national and international patents, and has published more than 75 articles, 3 book chapters and a book entitled “Thermal Measurements in Electronics Cooling”. Dr. Azar has also served as the editor in chief of Electronics Cooling Magazine, the premier resource for practitioners in the field of electronics thermal management, from the publications founding in 1995 to 2006.

“Battery Cooling in Automotive and the Electrification of Transportation” is a live interactive webinar. The webinar will be one hour in length with a thirty-minute question and answer period. The webinar will be recorded, and all registrants will receive a link to the recorded webinar.

Webinar: Heat Pipes & Vapor Chambers – How They Work and Their Deployment in Electronics Thermal Management, 10-22-20, 2PM EST

Heat pipes and vapor chambers are often lumped into liquid cooling, but, they are not actually cooling they are in fact moving heat from a hot location to another location where it is dissipated. And how they operate, how to choose them, and how to deploy them is a very important part of the thermal engineer’s toolbox. And we have a free webinar on this topic to help train you.

Our webinar “Heat Pipes & Vapor Chambers – How They Work and Their Deployment in Electronics Thermal Management” is being held at 2PM Eastern time on 10-22-20. In this webinar we’ll answer questions such as:

  • How do heat pipes and vapor chambers work?
  • Why heat pipes are not liquid cooling?
  • When is it best to use a heat pipe and when is it best to use a vapor chamber?

The webinar will be recorded, and for those who register, we will provide the recording for your review.

While the webinar lasts about an hour, we’ll have about 30-minutes for a Q&A afterward. Don’t delay, sign up today at the button below! NOTE: this webinar had been scheduled for 10/15 but due to scheduling conflicts, our team needed to move it to 10/22.

Have questions about heat pipes and vapor chambers? email us at and we’ll be happy to answer them and direct you to the right solution.

How to choose the best cold plate and deploy it for electronics cooling.

Liquid cooling has been increasing in use for many years and this corresponds to the increase in the power and density of electronics. Indeed, “The increase in computer density will continue to make air cooling less and less feasible, compared with liquid cooling. Between 2018 and 2023, the engineered fluids market is projected to grow at a CAGR of 8.8% to reach $1,304 million, from $854 million in 2018, Out of all the market’s sub sectors, it is the heat transfer fluids (cooling) segment that is expected to register the highest CAGR. ” According to an article in Electropages by Nnamdi Anyadike.

So it is important for engineers to have the tools and knowledge necessary to implement liquid cooling. And we have 3 resources that are helpful:

First, our webinar on 9-17-20 “Selecting and Designing Liquid Cold Plates for Deployment in Electronic Systems”. This webinar is live and our speaker is Dr. Kaveh Azar, Ph.D. Here’s what we’ll cover:

The use of liquid cooling systems is becoming more practical and effective for managing skyrocketing increases in power dissipation. But how do you decide when you need to cool with liquid? How do you find the right liquid cooling system for your application? This section provides the best practices for implementing a liquid cooling system at the device level.
