Abstract:
A temperature control device provided with a fluid circulating and supplying system for circulating and supplying a thermal fluid adjusted to a prescribed set temperature from and to an object whose temperature is to be controlled, which controls a temperature of the object whose temperature is to be controlled by means of the thermal fluid supplied by the fluid circulating and supplying system, comprising:first heat exchanging means, located in the fluid circulating and supplying system, for carrying out heat exchange with thermal fluid returning from the object whose temperature is to be controlled;second heat exchanging means, located in the fluid circulating and supplying system in a position leading from the first heat exchanging means to the object whose temperature is to be controlled, for adjusting the thermal fluid to the set temperature by carrying out heat exchange with thermal fluid passing therethrough;a bypass passage for splitting and supplying thermal fluid in the fluid circulating and supplying system from a position leading from the object whose temperature is to be controlled to the first heat exchanging means, to a position leading from the first heat exchanging means to the second heat exchanging means; andflow ratio regulating means for regulating a flow ratio between the thermal fluid passing through the first heat exchanging means and the thermal fluid passing through the bypass passage.
