    FR24 receiver Max accepted temperature?

    If the answer is somewhere here, im sorry but i have not been able to find it.

    I have installed the receiver into a waterproof case (Im sorry I dont know the technical word in English) at the botton of the mast in order to use the 5 meters antenna cable. Im checking the temperature of the equipment through its private IP.
    The temperature just now (21:37 GMT+1) is 51,63C (Outside temp now is 23C).

    My question is: what is the maximum temperature that the receiver can reach (before collapse...) ?
    The case is not small as you can see.
    Thanks in advanced.

    Those are internal sensor readouts. And as far as I am aware it is sent as part of the FR24 monitoring.

    The figure is not openly available, but if they find it is high they contact the feeder I think

    I've often wondered about putting a heatsink inside such a box thermally connected to a heatsink outside the box using thick brass or aluminium bolts as heat pipes through the box walls.

    We have no known temperature issues with the FR24 box. Temperature is monitored by FR24 and we will contact host if there are any issues.

    Thanks for the replies:
    48,35C 08:15hrs Outside temp: 21C
    53.98C 12:18 28C
    55.30C 13:08 28C
    58.51C 14:20 27C
    64.41C 15:46 29C
    66.04C 16:32 28C
    Max of the day now 66,84C at 16:57 (GMT+1) Outside temp: 28C
    The case is set heading west side of the wall what means the sun will hit it directly after midday.
    I would like to maintaing the case fully closed (without any hole) in order to keep the receiver fully protected.
    Lets see. Peterhr: I have thought about heat sink you mentioned. I will stay checking the temp periodically during the hottest hours of the day.

    I have same fr24 box, smaller case but same type, fixed on chimney facing north so sunlight exposure is minimum. Working for a year now with summer air temperature up to 39-40 degreess celsius.
    Just protect case from direct sunlight with some kind of board or similar.

    Protect ALL 4 sides + front ot the box with "heat shield".

    These simple metal pieces have been used successfully in all outdoor installations in WSSS.

    Those road side speed cameras, lamp post traffic monitoring cameras, traffic light controller boxes, etc, all have "heat shields" installed outside the boxes.

    I cover the front and top sides of the case with a "Sun car protection..." i hope it helps a bit. See photo.

    About the metal pieces like a "heat shield", it must be a special metal because if not it can be like an oven.

    I think the idea with the metal panels is that they are mounted away from the box and that there are wide air gaps - to the metal gets hot and air movement (the breeze and convention from the hot surfaces) carries the heat away

    Not special metal. Just ordinary metal mounted about 1 inch to 2 inches air gap from the box.

    The air gap will allow the heat to be blown away. The "heat shield" will prevent DIRECT sunlight from shining on the weather proof box.
