Cooling device, temperature control device and printer

A temperature control device for controlling a temperature of an object, the temperature control device comprising:

• a cylindrical body having thermal conductivity;
• a plurality of thermoelectric converters arranged along a periphery of the cylindrical body and disposed dispersedly along an axis of the cylindrical body;
• a feeder cable connecting two or more thermoelectric converters arranged along the periphery of the cylindrical body in series among the plurality of thermoelectric converters to form each of a plurality of sets of thermoelectric converters, the feeder cable forming a circuit for power feeding of the each of plurality of sets of thermoelectric converters;
• a driver configured to feed power to the plurality of thermoelectric converters via the feeder cable;
• and
• a polarity switching circuit configured to electrically change a power feed polarity for the circuit.

A cooling device comprising:

• a cylindrical body having thermal conductivity;
• a plurality of thermoelectric converters arranged along a periphery of the cylindrical body and disposed dispersedly along an axis of the cylindrical body;
• a feeder cable connecting two or more thermoelectric converters arranged along the periphery of the cylindrical body in series among the plurality of thermoelectric converters to form each of a plurality of sets of thermoelectric converters, the feeder cable forming a circuit for power feeding of the each of plurality of sets of thermoelectric converters;
• a driver configured to feed power to the plurality of thermoelectric converters via the feeder cable,
• wherein, in response to contact of the object with the cylindrical body, the driver sets a voltage to be supplied to a first set of thermoelectric converters corresponding to a cooling object along an axis of the cylindrical body to be higher than a voltage to be supplied to a second set of thermoelectric converters not corresponding to the cooling object along an axis of the cylindrical body, the first set of thermoelectric converters and the second set of thermoelectric converters being included in the plurality of sets of thermoelectric converters.
