Thermal protection of electronic devices based on thermochemical energy storage …
To ensure thermal protection of the black box, the temperature of the circuit board in the inner part must be below 125 C after 0.5 h at an ambient temperature of 650 C or 1 h at an ambient temperature of 300 C. As shown in Fig. 2, a muffle furnace is used to create a high-temperature environment of 300 or 650 C, with the black box …
