1.8.6.3 Heat Sink Selection Example
For preliminary heat sink sizing, the die-junction temperature can be expressed as follows:
Tj = Ta + Tr + (qjc + qint + qsa) * Pd
Where:
Tj is the die-junction temperature
Ta is the inlet cabinet ambient temperature
Tr is the air temperature rise within the computer cabinet
qjc is the die junction-to-case thermal resistance
qint is the adhesive or interface material thermal resistance
qsa is the heat sink base-to-ambient thermal resistance
Pd is the power dissipated by the device
During operation the die-junction temperatures (Tj) should be maintained less than the value specied in
Table 3. The temperature of the air cooling the component greatly depends upon the ambient inlet air
temperature and the air temperature rise within the electronic cabinet. An electronic cabinet inlet-air
temperature (Ta) may range from 30 to 40 C. The air temperature rise within a cabinet (Tr) may be in the
range of 5 to 10 C. The thermal resistance of the thermal interface material (
qint) is typically about 1 C/W.
Assuming a Ta of 30 C, a Tr of 5 C a CBGA package qjc = 0.095, and a power consumption (Pd) of 3.0
Watts, the following expression for Tj is obtained:
Die-junction temperature: Tj = 30 C + 5 C + (0.095 C/W + 1.0 C/W + Rsa) * 3.0 W
For a Thermalloy heat sink #2328B, the heat sink-to-ambient thermal resistance (Rsa) versus airow
velocity is shown in Figure 18.
