Abstract
PURPOSE:To increase the temperature of a circulating medium to a set constant temperature state with saved energy, by raising the temperature of the circulating medium through the use of self-heating caused at a preparatory operation of a body to be controlled. CONSTITUTION:A laser oscillator 10 is provided with a radiator 16, which is linked with a constant temperature tank 8 by a secondary piping 17. The tank 8 is provided with a heating element H and thermostates Th1-Th3 and connected to a cooling element 1 by a primary piping 9. Cutting and welding and the like are made for a metallic plate 15 with an oscillated laser 14 of the laser oscillator 10. Before the start of work, a cooling medium is heated to a certain degree by applying power to the element of the tank 8, the then the power application is stopped to preparatorily operate the laser oscillator 10. The radiator 16 is heated with the self-heating generated at this preparatory operation and the temperature of medium is raised. Thus, the heating of the medium can economically be performed.
