Standard and customer-specific housing components optimally combined
REQUIREMENTS AND IMPLEMENTATION
HEITEC developed an economical housing for a manufacturer of measurement and test engineering solutions for aerospace and automotive engineering. It’s comprised primarily of standard components and was adapted to meet the customer’s requirements using customer-specific parts.
In many areas of aircraft construction, there’s a basic need for flexible measurement and test systems that can cover a wide variety of tasks. The populated enclosure integrated into the customer’s test cabinet serves as the basis for an expandable, multichannel test system for the high-precision control of hydraulic and electrical components. With customer-specific modules installed, it’s possible to operate equipment like the movable platforms in aircraft test beds and flight simulators.
Complex and specialized test electronics enable highly available, extremely reliable operating solutions. High packaging density for electronics and a design for the intended application define the “frame” for the device housing. The result is a 4U, 19-inch subrack that can be seamlessly integrated into the test system. The basic housing structure is designed in 19-inch technology in such a way that the side panels and mounting rails are implemented using standard parts. This allowed a fast and economical provision of installation space for the desired arrangement. The customers’ backplane is installed in the enclosure along with an appropriate PSU and is completely wired by HEITEC.
Because the installation location made ventilation from bottom to top impossible, a 4U HeiPac Vario subrack was selected that provides ½U of space above and below the card cage. The bottom cover has perforations at the front where cool air can be drawn in and blown out by the fan integrated into the rear panel. To direct the flow of air through the enclosure, customer-specific air partitions were installed in the system to ensure effective ventilation of the electronics.
In addition to the housing layout and integration of the backplane and power supply, HEITEC is also responsible for quality assurance. Each system undergoes a function, high-voltage, and insulation test.
