6U SEVENHEX-CHP Description
Sealed, 1" pitch, high performance dry-air 6U chassis incorporates seven heat exchangers, 32, 36 or 46 super conductive heat pipes & air re-circulation fans inside. This minimum maintenance ATR is ideal for applications where ambient air is laden with hostile or harmful contaminants.
Heat is conducted to hollow sidewalls, top cover, bottom cover & rear panel heat exchangers where it is dissipated to the ambient environment by forced air rear fans or by vehicle air plenum. Two additional internal card-cage heat exchangers recirculate air & 32-46 integrated heat pipes provide fast passage for heat to exit the internal card-cage. Internal air recirculation fans ensure constant airflow across modules.
CM-ATR-1S5/SEVENHEX-CHP
The 6U SEVENHEX-CHP chassis is available in 5, 7 & 12 slot versions, supporting Gen 3/4/5 VPX backplanes. Total PSU power of up to 1200 watts may be installed. Custom modifications can be designed upon request.
Internal layout is divided into 4 independent metallic partitions. I/O section at the front, card-cage, PSU section & exhaust fans at the rear. This improves EMI/EMC performance & reduces PSU noise on system electronics.
This 1" pitch chassis has been designed exclusively for VPX wedgelock IEEE P1101.2, VPX VITA 46.0/.1/.10/.3/.4/.7 conduction cooled modules.
6U SEVENHEX-CHP Performance
The 6U SEVENHEX-CHP chassis is suitable for high wattage sealed applications that demand superior cooling capability.
Chassis Global Thermal Resistance (CGTR) coefficient:
ΔT/W = 0.04°C (5 Slot) | ΔT/W = 0.03°C (7 Slot) | 0.025°C (12 Slot).
Chassis Payload Thermal Resistance (CPTR) coefficient:
ΔT/W = 0.05°C (5 Slot) | ΔT/W = 0.035°C (7 Slot) | 0.029°C (12 Slot).
For reliable operation it is recommended the maximum Payload Power not be exceeded. Subject to operating conditions.
All CM 6U ATR chassis are delivered tested, qualified and certified per Military Standards MIL-STD-461E & MIL-STD-810F.
6U SEVENHEX-CHP Backplanes
CM 6U SEVENHEX-CHP military backplanes are 100G Gen 4 rated, available in VPX 1" pitch format with 0.8" pitch module compatibility. This latest generation of high performance backplane is fitted with VITA 46.30 MultiGig RT3 Tyco connectors for high speed 'board-to-bus' transmission.
SEVENHEX-CHP backplanes are fitted with Dual Temperature Supervisory Units for independent temperature control of system devices (heaters, fans, etc.). The backplane drives two front panel LED indicator sets (16 LEDs in total), providing all system status information and four user definable LEDs for customer applications.
The SEVENHEX-CHP has been developed in compliance with VITA 46.3, VITA 65, VITA 66.5 and VITA 67 standards. High Speed Tachyon 100G PCB substrate material or Megtron 7 ensures the backplane delivers truly exceptional performance.
SEVENHEX-CHP backplanes have been specifically developed in alignment with the SOSA™ technical standard, delivering high current in +12VDC and +3.3VDC. The SEVENHEX-CHP backplane mates with a single or twin PSU modules that supply 600 watts each (+12VDC @ 42A and +3.3VDC @ 23A) to support even the most demanding VPX modules.
A SEVENHEX-CHP backplanes are customized to each customers requirements. Backplanes are developed using Allegro high speed design tools with critical emphasis on trace length and impedance matching of all differential and single tracks.
CM undertake complete backplane customization according to customer VPX topology and I/O requirements, delivering a fully 'turn-key' solution.
Backplane wiring integration is facilitated by a 60mm bottom cavity clearance and a 63mm clearance behind the enclosure front panel for connector I/O.
The SEVENHEX-CHP backplane is fitted with Class 1 military power input connectors that offer reliable shock & vibration interconnectivity between the backplane and PSU module(s). They allow for high DC current rates with low voltage drops & minimum contact heating.
The SEVENHEX-CHP 6U backplane is supplied with a military conformal coating. The VPX backplane is partially coated per MIL-I-4658C in areas in which do no affect VPX connectors. Read More
