BeagleY AI heating issue

General Discussion

Hi everyone,

I am working on BeagleY AI board and doing some extensive work on it. I am capturing a sensor and camera data together on the board. Data is being stored on the SD card. I have already added the raspberry Pi heatsink fan (which is suggested in the user guide) I tried different test where test1 was capturing data indoor where I logged the on-board temperature by using following code:

def read_thermal_zones():
readings = []

for zone_path in sorted(Path("/sys/class/thermal").glob("thermal_zone*")):
    temp_path = zone_path / "temp"
    type_path = zone_path / "type"

    if not temp_path.exists():
        continue

    try:
        raw_temp = float(temp_path.read_text().strip())
        temperature_c = raw_temp / 1000.0 if raw_temp > 1000 else raw_temp

        if type_path.exists():
            zone_type = type_path.read_text().strip()
        else:
            zone_type = zone_path.name

        readings.append((zone_path.name, zone_type, temperature_c))
    except (OSError, ValueError):
        continue

return readings

The indoor temperature were logged between 60-70 C. Whereas when I captured data outdoor the temperature of beagleY board was logged around range 90-102 C and the data capture was malfunctioned.

Can anyone help me find way to cool the device down when capturing data outdoors?

Thanks!

Fans or a fan…

I use this nifty thing I found. It has a good form factor for the BeagleY-AI. I think it is the RPi 5 Fan PCB.

It fits as a Cape well. The plastics on the PCB fit into holes to secure it in place.

One idea, and of course I got too excited when I got it set up, maneuver the heatsink padding/thermal padding underneath the heatsink metal to fit to the BeagleY-AI processor core and other parts. Floating thermal padding will not help that board for now.

About that RPI 5 fan Cape PCB thing…

Let me look around. I am sure I can find one again.

Update

Me again. So, I think Waveshare has them. Do not quote me on it but I saw two different types. I guess there is something called a B too.

Are you sure those numbers are in Centigrade, not Farenheit? I know Beagles, RPis, and other SBCs can get quite toasty, even in normal use. But if one gets hot enough to boil water, isn’t fire risk a concern? Off the top of my head, I don’t even think the Beagle Black Industrial is even rated to run at 100 degrees C.

[Edit] Even if there’s nothing combustible close to the heat source, a 90 degrees C component is enough to give you a nasty burn, should you touch it.
