Heat Sink Selection Examples
The following section provides a heat sink selection example using one of the commercially available heat
sinks.
For preliminary heat sink sizing, the die-junction temperature can be expressed as follows:
TJ = TI + TR + (θJC + θINT + θSA) × PD
where
TJ is the die-junction temperature
TI is the inlet cabinet ambient temperature
TR is the air temperature rise within the computer cabinet
θ
JC is the junction-to-case thermal resistance
θ
INT is the adhesive or interface material thermal resistance
θ
SA 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 within the range specified in
Table 2. The temperature of air cooling the component greatly depends on the ambient inlet air temperature
and the air temperature rise within the electronic cabinet. An electronic cabinet inlet-air temperature (TI)
may range from 30
° to 40° C. The air temperature rise within a cabinet (T
R) may be in the range of 5° to
10
° C. The thermal resistance of the thermal interface material (θ
INT) may be about 1° C/W. Assuming a
TI of 30° C, a TR of 5° C, a FC-PBGA package θJC = 0.1, and a power consumption (PD) of 5, the following
expression for TJ is obtained:
Die-junction temperature: TJ = 30° C + 5° C + (0.1° C/W + 1.0° C/W + θSA) × PD
The heat sink-to-ambient thermal resistance (
θ
SA) versus airflow velocity for a Thermalloy heat sink
#2328B is shown in Figure 64.
Assuming an air velocity of 1 m/s, we have an effective
θ
SA+ of about 5° C/W, thus
TJ = 30° + 5° C + (0.1° C/W + 1.0° C/W + 5° C/W) × 5
resulting in a die-junction temperature of approximately 66, which is well within the maximum operating
temperature of the component.
