Abstract:
1. A cooling apparatus, comprising: a cooling unit for cooling an object to be cooled by a cooling amount in accordance with a level of a supplied drive signal; a temperature detector for detecting the temperature of the object; a drive circuit for amplifying the drive signal and supplying an output signal to the cooling unit, in which the drive circuit produces a circuit error when amplifying the drive signal; a memory for previously storing error correction data usable for correcting the circuit error produced by the drive circuit; and a control unit for generating the drive signal based on the detected temperature of the object, correcting error in the output signal based on the correction data stored in the memory, and outputting the generated drive signal to the drive circuit, in which the correction data stored in the memory is data obtained using a control temperature maximum value, a control temperature minimum value, a corrected fan speed maximum value, and a corrected fan speed minimum value as parameters.
