Patent ID: 7938174

Claim:
A temperature controlling apparatus that controls a temperature of a temperature-controlling object, the apparatus comprising: an atmospheric coolant circulating line that circulates a coolant through a cooling path arranged at the temperature-controlling object; a heat transfer plate heater that heats the temperature-controlling object; a coolant discharge part that discharges the coolant remaining in the cooling path when the circulation of the coolant is stopped; an open-close valve; and a controller configured to drive the open-close valve based on a detected temperature signal from a temperature sensor in the temperature-controlling object, wherein the controller is configured to direct the coolant circulating in the coolant circulating line and the heat transfer plate heater to control the temperature of the temperature-controlling object so that the temperature of the temperature-controlling object is controlled to be a low temperature; the controller is configured to stop the circulation of the coolant and direct the heat transfer plate heater to control the temperature of the temperature-controlling object so that the temperature of the temperature-controlling object is controlled to be a high temperature; and the controller is configured to stop the circulation of the coolant and direct the coolant discharge part to discharge the coolant remaining in the cooling path so that the temperature of the temperature-controlling object is controlled to change from a low temperature to a high temperature.
