Air flow inside the ECUTS is separated into a cool air intake column and a hot air exhaust column. The ECUTS pulls fresh air from the bottom rear of the test rack, and the column of cool air is guided toward the hot air exhaust vent on top of the test rack.Actively cooled components inside the test rack pull air from the air intake column and exhaust air towards the front of the test rack to the hot air exhaust column. The RMX-4002, if present, has a dedicated hot air exhaust panel on the front of the test rack.
The following figure shows the distribution of hot and cold air inside the ECUTS-16000 and ECUTS-16001.
The two air flow columns are separated to ensure that the air intake column is kept as cool as possible. In areas of the test rack where there are not hardware components separating the columns, the ECUTS has filler panels or brush panels to keep cool and hot air separate while still allowing cables to pass between the front and rear of the test rack.
To prevent the ECUTS from overheating, adhere to the following cool air intake and hot air exhaust guidelines when adding additional instruments or components to the ECUTS:
