THERMOELECTRIC DEVICE FOR CONTROLLING HEAT OF INTERNAL THERMAL ZONE IN A HARD DISK DRIVE AND HARD DISK DRIVE INCLUDING THE SAME, AND SYSTEM INCLUDING THE SAME

摘要

A thermoelectric device for controlling temperature of an internal thermal area in a hard disc drive, a hard disc drive and a system thereof are provided to guarantee operation reliability of the hard disc drive at extreme temperature without changing a set parameter of the hard disc drive. A method for controlling temperature of an internal thermal area in a hard disc drive includes a step of giving a first electric potential difference between a pair of electric contacts(210-1,210-2) to deliver first heat(120) to an external heat delivery interface(132) thermally connected to the outside of the hard disc drive(10) from an internal heat delivery interface(130) included in an inner interface thermally connected to the internal thermal area(20) of the hard disc drive; and a step of giving a second electric potential difference between the electric contacts to deliver second heat(122) to the internal heat delivery interface from the external heat delivery interface. The polarity of the first electric potential difference is opposed to that of the second electric potential difference. A thermoelectric device(200) of the hard disc drive is thermally connected to the air at the outside(300) of the hard disc drive and to the internal thermal area of the hard disc drive through the heat delivery interface.
