CM SixHex-16HP Hybrid ATR
The new SixHex-16HP Hybrid ATR introduces 16 Heat Pipes within CMs Six Heat Exchanger chassis to further reduce payload operating temperatures, improve system thermal performance and increase MTBF by a factor of 1.4.
This dry-air hybrid enclosure incorporates the latest technologies in both conductivity and phase transition to increase thermal transfer through the integration of 16 heat pipes. This provides a 15% increase in system power dissipation with respect to our standard SixHex series. This cost effective performance enhancement benefits long term system operational reliability in military system applications with high power dissipation requirements.
SixHex-16HP ATR enclosures incorporate all features and practical functionalities that are defined in the SixHex series general specifications catalog. All electrical, mechanical and environmental characteristics remain universal, resulting in only a 3% increase in chassis weight. The embedded hybrid heat transfer mechanism improves system payload MTBF by 40%, performing under a reduced thermal profile of 5ºC less on average.
The 16 heat pipes remove heat directly from the internal chassis card-cage, providing an "expressway" to the ambient environment. CM´s unique condenser modules optimize heat dissipation through the sidewall heat exchanger´s forced air flow. Extreme care has been taken to ensure the heat pipes do not come into direct contact with valuable system electronics. Even in the event of improbable pipe failure, drops of cooling liquid will never reach the card-cage.
Heat pipes become more efficient when internal chassis temperatures rise so that their benefits can be fully realized under extreme climatic operating conditions. The installed heat pipes are fully MIL certified, externally fitted, have no moving parts and offer zero maintenance in service.
Upgrade with confidence
Customers wishing to improve the SixHex series performance should consider 16HP integration as a direct upgrade to systems already in service. Compatibility also extends to the Mounting Tray facilitating immediate replacement in the field. The SixHex-16HP is fast becoming the COTS preferred choice for system integrators who wish to employ the latest high power VPX modules.» Our smallest 5 slot ½ ATR 9kg (25) chassis is now capable of dissipating up to 700 Watts.
» The popular 7 slot ¾ ATR 13kg (35) chassis is now capable of dissipating up to 1000 Watts.
» The flagship 12 slot 1 ATR 18kg (45) chassis is now capable of dissipating up to 1500 Watts.
At CM Computers we consider the release of a new generation of military ATR chassis when the temperature of its payload has been decreased by approximately 10ºC with respect to the previous generation, indicating the system MTBF has doubled. Following this criteria, our latest 16 heat pipe ATRs could be considered a "half generation" series (5ºC off). It is interesting to remark that approximately 85% of the total heat transferred is attributed to the six large cross flow heat exchangers (SixHex), whilst the remaining heat is dissipated via the new embedded heat pipes.
CM SixHex-16HP enclosures are maintenance-free and do not require air intake dust filters. This stand alone single pack ATR solution also incorporates the exclusive CM universal "floating" card cage capable of accommodating and freely intermixing all standard conduction-cooled and air-cooled Eurocard formats.
