Connection topology graph:
Use iperf3 command simulation using WiFi board, and then use
cat/sys/class/thermal/thermal_zone0 / temp
iwpriv ra0 stat
view the CPU temperature and WiFi card temperature, respectively.
Here is the integrated test script.
Test scripts:
#!/bin/bash
iperf3 -s -p 5201 &
iperf3 -s -p 5202 &
iperf3 -s -p 5203 &
echo "Three iperf3 server instances are running in the background on ports 5201, 5202, and 5203."
(while true; do cat /sys/class/thermal/thermal_zone0/temp; sleep 30; done) &
(while true; do iwpriv ra0 stat; sleep 30; done) &
Here I will divide the temperature comparison between the use of heat sink and the use of heat sink.
Testing photo:
No heart sink
With heart sink
The corresponding temperature was recorded at roughly 20-minute intervals.Mainly look at BE1400 temperature comparison (here just casually record CPU temperature)
| No heart sink | With heart sink | |||
|---|---|---|---|---|
| Number of measurements | CPU temperature(℃) | WiFi card temperature(℃) | CPU temperature(℃) | WiFi card temperature(℃) |
| first | 47.587 | 68 | 47.961 | 48 |
| second | 48.573 | 75 | 49.698 | 60 |
| third | 48.861 | 77 | 50.085 | 62 |
| fourth | 49.110 | 75 | 50.385 | 62 |
| fifth | 48.986 | 77 | 51.271 | 66 |
| sixth | 48.536 | 75 | 50.972 | 64 |
| seventh | 48.473 | 77 | 50.097 | 60 |
| eighth | 48.411 | 75 | 50.934 | 64 |
After using the heat sink, the temperature of BE14000 has decreased significantly, and the heat dissipation effect is very good after adding the heat sink.
have u been able to also test this in a case?
