Vice-President of Sales and Business Development Steve Nolan and Product Engineering Manager Greg Wong manned the ATS booth during the show and took visits from sales representatives, distributors, and engineers from across the industry, some were familiar faces and some were learning about ATS expertise in thermal management of power electronics for the first time.

The highlighted products were ATS liquid cold plates, which boast 30% better thermal performance than comparable products on the market and are easily customizable to meet a variety of applications, and the line of ATS high-performance round and flat heat pipes, which is expanding by the end of 2018 to give ATS the broadest offering of off-the-shelf heat pipes on the market.

“When people start having thermal issues, it’s because they’re dissipating a lot of power and then you start to need things like heat pipes and liquid cold plates,” said Wong. “In most of these applications, people are talking about custom designs, which is where we have a lot of strength working with the customer and designing these custom applications.”

ATS cold plates were also featured in the Texas Instruments (TI) booth as part of a “98.5% efficiency, 6.6-kW Totem-Pole PFC Reference Design for HEV/EV Onboard Charger.” The base of the design was silicon carbide (SiC) MOSFETs with a C2000 microcontroller with SiC-isolated gate drivers, according to information presented by TI.

Underneath the prototype that was on display at the TI booth was a custom ATS cold plate to meet the charger’s thermal requirements.

“It’s a great example of how we can customize our cold plates to meet a particular application,” Wong added. “A lot of people were taking pictures of that piece at the TI booth and a lot of people were talking with TI about it. The booth was mobbed every time I went over there.” 

ATS participation in the TI booth at APEC 2018 is a continuation of the strong working relationship between the two companies. ATS has also been a key reference design supplier of heat sink solutions for TI’s audio evaluation module.

Wong and Nolan also learned a lot about the future of power electronics, including the prevalence of SiC and gallium nitride (GaN) components in the industry and the increasing popularity of liquid cooling, to keep ATS current on industry trends and ensure that the innovative thermal solutions that ATS provides can meet ever-rising power demands.

While there is a lot that is new in the industry, IGBT designs continue to be popular and the standard IGBT footprint matches perfectly with ATS off-the-shelf cold plates to make an easy fit for engineers designing liquid cooling solutions.

“If people are still making devices in that IGBT footprint then it will bolt directly to the cold plate, which is good news because that package is very popular, so it’s good to have those standard products,” Wong explained.

Watch the video below as Greg Wong of ATS was interviewed by Alix Paultre of Power Electronics News at APEC 2018 about ATS heat pipes and cold plates.

ATS has the expertise, products, and resources to provide off-the-shelf and customized thermal solutions for the power electronics industry. Learn more about the full line of products at https://www.qats.com or contact ATS at ats-hq@qats.com.

Thermal Challenges and Solutions for Industrial Solid State Lighting Applications

ATS will be at APEC 2016 in Long Beach California on March 20-24th.  Our Sr. Director of Product Development, Peter Resca will be speaking on “Thermal Challenges and Solutions for Industrial Solid State Lighting Applications” and he’ll be chairing the thermal track at APEC 2016.  Here’s a synopsis of what Peter will be talking about at APEC:

The focus of this presentation is to describe the challenges of thermal management in Industrial lighting applications, the implications of temperature stress on the system, a practical guide to identifying the problem and various methods to resolve the issue.

The emergence of LED technology has changed the shape of the lighting industry. The implementation of LED applications allows the designers to take advantage of several key characteristics of the technology. This includes energy efficiency and the ability to control the direction, color, timing, etc. of the light source itself. These attributes can be particularly effective in industrial and commercial applications where harsh environments, building automation controls and cost of deployment may be different than consumer fixtures.

Light emitting diodes are semiconductor devices and thus they have the benefits and limitations of such devices. The benefits include optimum energy efficiencies, volume manufacturing and hi package density. One key factor in deployment is how to efficiently dissipate the power produced. Lack of attention to thermal stress can lead to many undesirable results. Performance can be impacted as an LED spectrum can change as a factor of heat. Color change can cause issues in fixtures for color matching and design elements. Temperature stress is also the key contributing factor to failure mechanisms. Poor thermal management therefore can affect fixture life, time to replacement and visual quality, if portions of the LED matrix age prematurely.
Computational Analysis of an LED Light

To identify the challenges and address the concerns it is helpful to begin with a full model of the application. This can start at the outside environment, to the enclosure, the PCB, the LED package and the die. Additionally it is helpful to consider how power is dissipated including conduction, convection and radiation. With the problem defined and the available paths known, an optimized solution can be developed. There are multiple variables to the equation, but by identifying the dominant factor a resistance network can then be developed which will lead to a solution that can be validated analytically, computationally and experimentally.

Experimental test setup for LED thermal management

The thermal management of solid state lighting has unique challenges when deployed for industrial and commercial installations. Replacement cost can be high if accessibility is limited. The application may require high intensity or large coverage which increases the overall dissipation, often in a small package. Frequently, the environment is a critical design factor with outdoor implementations requiring consideration of solar loading and sealed enclosures. Finally, there is an increase in building automation which can add an element of sensing, communication and computing control in the light head to be considered which is equally sensitive to the local ambient. (Note: A simple case study illustrating the process will be provided as part of the presentation)

The solid state lighting market continues to grow and allow for increasingly sophisticated applications. It is critically important that design and system engineers understand the challenge and are equipped to address these concerns. With careful analysis of the environment, calculation of the source, examination of the options and implementation of the solution, engineers can take advantage of LEDs to improve current applications while exploring new markets for the technology.
