1. An electronic device, comprising:
a card slot;
a heat transferrer;
a heat dissipator connected to the heat transferrer to allow heat transfer from the heat transferrer;
temperature detector to detect a temperature of the card slot and a temperature of the heat dissipator; and
contact switch to switch between a contact state and a non-contact state of the card slot and the heat transferrer,
wherein the contact switch places the card slot and the heat transferrer in contact with each other when the temperature of the card slot is higher than the temperature of the heat dissipator, and places the card slot and the heat transferrer out of contact with each other when the temperature of the card slot is lower than or equal to the temperature of the heat dissipator.
