What device is used to heat the chip on the motherboard in low temperature outdoor conditions? [Copy link]

Has anyone had experience with this? When the device is taken outdoors in the north, the temperature of the motherboard may be lower than -20 degrees. Some components on the board are 0-70 degrees, which is the commercial standard, and they cannot be started. What components can be used to heat the motherboard quickly and reliably? The power supply on the motherboard is 12V, and it seems that the power is not that great...

It's useless to use it outdoors, why not bring it indoors?

The heating element can be a power resistor, which must be temperature controlled and arranged in a reasonable position. The specific power needs to take into account the external thermal resistance of the temperature-exceeding device and the internal heating situation. It is best to use a vertical circuit board installation for outdoor equipment. On the one hand, it has better waterproof and dustproof effects, and on the other hand, the heating element can be arranged at the bottom or top to increase or decrease the temperature of the system.

Use cement power resistor as heater and control it with temperature switch; keep the outside well insulated.

I don't know about this.
