Thermal Consideration continued
The PKM4000E series DC/DC converters can be ordered with
a heatsink (HS) option. The heatsink option have
approximately 5 °C improved derating compared with the
PKM4000E without heatsink. The HS option is intended to be
mounted on a cold wall or heatsink to transfer heat away from
the converter and further improve the cooling of the converter.
Definition of reference temperature (Tref)
The reference temperature is used to monitor the temperature
limits of the product. Temperatures above maximum Tref are
not allowed and may cause degradation or permanent
damage to the product. Tref is also used to define the
temperature range for normal operating conditions.
Tref is defined by the design and used to guarantee safety
margins, proper operation and high reliability of the module.
Ambient Temperature Calculation
By using the thermal resistance the maximum allowed
ambient temperature can be calculated.
1. The power loss is calculated by using the formula
((1/η) - 1) × output power = power losses (Pd).
η = efficiency of converter. E.g 90 % = 0.90
2. Find the thermal resistance (Rth) in the Thermal Resistance
graph found in the Output section for each model.
Calculate the temperature increase (T).
T = Rth x Pd
3. Max allowed ambient temperature is:
Max Tref - T.
E.g
PKM 4810E PI at 1m/s:
1. ((
) -
1) × 82.5 W = 9.17 W
2. 9.17 W × 4.7°C/W = 43.1°C
3. 120 °C — 43.1°C = max ambient temperature is 76.9°C
The actual temperature will be dependent on several factors
such as the PCB size, number of layers and direction of
airflow.
