Thermal Considerations
8.1. Available Processors
Please refer to the chapter 16 “Technical Specification”.
The list of processors is not complete and may be extended over the product lifetime.
8.2. Convection Cooling
The KBox C-101 is designed for ambient air convection cooling within the specified ambient air temperature ranges.
Therefore it is imperative that air flow to and from the unit is guaranteed.
In addition, implementers must empirically verify the cooling concept for the KBox C-101 including optionally installed
devices prior implementing the unit in the intended application.
8.3. Active Cooling via the optional Fan Tray
For applications where convection cooling is not sufficient, there is the possibility to use the optional fan tray (externally
mounted to the KBox C-101). The optional fan tray extension allows the KBox C-101 to operate at higher ambient
temperature conditions and provides a higher airflow through the chassis providing better cooling of the system internal
components.
8.4. Minimum System Clearance
To provide a maximum of airflow through and around the box, minimum distances to surrounding parts must be observed
(please refer to the chapter 11 “Control Cabinet Mounting” and Fig. 35).
8.5. Maximum Temperatures
As the Intel ® processors provide only certain settings for maximal power consumption, some typically are used for the
following table. This table can be seen as a guideline.
KBox C-101 without Fan Tray KBox C-101 with Fan Tray
Processor Power
Consumption Max. ambient
Temperature [°C] Approx. System internal
Temp. Rise [°C] Max. ambient
Temperature [°C] Approx. System internal
Temp. Rise [°C]
25W 65 5 70 2
37W 59 5 65 2
47W 50 5 55 2
The maximum system ambient temperature depends mostly on the power consumption of the processor
and the chipset.
