Abstract

A fluid temperature control device, measuring the temperature error between the target temperature and the current temperature of fluid, and transferring the heat given off by heat sources to the fluid; a plurality of heat sources separately installed, providing a plurality of control means(combinations); the device picking out an optimum combination to make the temperature of fluid remain at the target temperature; the characteristics comprising: the mentioned plurality of control means having control over the ON/OFF of the heat generated by heat sources in response to the temperature error between the target temperature and the current temperature; in addition, the plurality of control means calculating the ON/OFF time ratio in a cycle and predicting the thermal capacity of the fluid, then selecting a combination of heat sources according to the predicted thermal capacity for controlling the temperature.
