THERMAL SWITCH, TEMPERATURE ADJUSTMENT STRUCTURE, AND BATTERY PACK

摘要

Provided are a thermal switch with a simple structure capable of changing the heat transfer performance thereof according to temperature, a temperature adjustment structure equipped with the thermal switch, and a battery pack. The thermal switch (1) comprises: a first protective layer (2) which receives heat; a radiation layer (4) which is joined onto the first protective layer (2) and changes emissivity when temperature changes; and a second protective layer (3) which is arranged opposite the radiation layer (4) with a gap (5) formed with the radiation layer (4) and receives heat from the radiation layer (4). The emissivity of the radiation layer (4) changes with change in temperature, so in a thermal switch (1) wherein emissivity increases with a rise in temperature, heat is not liable to be transferred from the first protective layer (2) to the second protective layer (3) when the temperature is low, but is liable to be transferred from the first protective layer (2) to the second protective layer (3) when the temperature is high.
