ATS Expands in the COTS Market with its Wind Tunnel Sale to the US Navy

ATS has continued to expand in the COTS industry because of its expertise in resolving thermal challenges through its consulting services, cooling solutions, and thermal test instruments. Most recently, the CWT-107 open loop wind tunnel was sold to the United States Navy for use in their Research Development Labs.

 

CWT-107

CWT-107 Open Loop Wind Tunnel

The CWT-107 is a research quality wind tunnel designed for multiple PCB and component level testing. It is used in air flow characterization and flow visualization, thermal resistance measurements and generation of P-Q curves. The large test section (24″ x 2″ x 7″) is designed to accommodate multiple PCBs, as seen in a typical ATCA chassis. The wind tunnel can also be used to characterize different heat sink sizes for natural and forced convection cooling. Additionally, multiple heat sinks can be tested side by side to determine their thermal performance in the same environment.

The following video is a brief demonstration and walk through of the CWT-107 Open Loop Wind Tunnel:

ATS Officially Granted Access for Government Contracts

COTS Advanced Thermal Solutions, Inc., (ATS), is now officially in active status with the United States Federal Governments System for Award Management (SAM). The System for Award Management (SAM) is the Official U.S. Government system that consolidated the capabilities of CCR/FedReg, ORCA, and EPL, for vendors doing business with the Federal government.

Military electronics systems include communications, weapons, reconnaissance, targeting and evasion, delivery and functionality. Power dissipation in these devices is at an all-time high and thermal management is becoming even more of a critical issue. Along with power and heat challenges, engineers must factor in remote locations, rough handling and temperature extremes, in which systems must continue to function reliably. Further, many military systems require small form factors leaving less room for conventional heat dissipation solutions. ATS has already received its several contracts with the US Government and expects to expand its current role in the military, defense, and aerospace markets.

New maxiFLOW DC-DC Brick Heat Sinks Ideal for Military-COTS Applications

ATS has recently launched a new product line of maxiFLOW heat sinks, specially designed to cool DC-DC converters. The new line of heat sinks can be used with Vicor’s DC-DC converter Bricks, including their military-COTS applications.

Vicor’s Maxi, Mini, and Micro series DC-DC converters are relied upon by over eight thousand OEMs for their proven performance, broad coverage of input and output voltages, ease of mechanical mounting and thermal management flexibility. These converter modules use advanced power processing, control, and packaging technologies to provide the performance, flexibility, and ruggedness expected in a Military COTS product. High frequency ZCS/ZVS switching, advanced power semiconductor packaging, and thermal management provide high-power density with low noise and high efficiency.

maxiFLOW Heat Sink for Half Brick DC-DC Converters

 

ATS’ patented maxiFLOW technology cools millions of BGAs and other PCB components. The same technology is now available for cooling eighth, quarter, half and full brick modules, such as the Micro, Mini, and Maxi series from Vicor. Unlike other converter heat sinks, the patented maxiFLOW heat sink design reduces air pressure drop and provides greater surface area, increasing thermal performance by 30-200%.

Vicor’s Micro, Mini, and Maxi DC-DC Converters

Vicor’s offering of full, half, and quarter-brick modules feature a patented low noise design with the highest reliability and power density available. Fully encapsulated, Maxi, Mini and Micro series DC-DC converters utilize a proprietary spin fill process that assures complete, void free encapsulation making them suitable for the harshest environments. Two grades (H & M) are available with temperatures to -55°C operating and -65°C storage. H & M-Grade modules are qualified to the stringent environmental tests of MIL-STD-810 and MIL-STD-202 and undergo 100% Environment Stress Screening.

By combining technology from industry leaders Vicor and ATS, it can be ensured that DC-DC converters will have superior performance in the harshest environments, which is vital for military and aerospace applications.
