The present invention has the above configuration,
The temperature of the object to be cooled can be measured indirectly, and the temperature of the object to be cooled can be measured stably and automatically. Therefore, the operation of inserting the temperature sensor as in the related art is unnecessary, and there is no variation in the measured temperature due to the insertion failure of the temperature sensor. Further, by using the wet bulb temperature sensor, it is possible to measure not only the temperature but also the pressure in the cooling bath with one sensor. If a water tank is installed in the outside air introduction line, clean air will always contact the water in the water tank, and slag, etc., of objects to be cooled floating in the cooling tank will not enter the water tank, making it extremely sanitary. It is a target. Further, the configuration in which a part of the water at the heat exchanger outlet side of the cooling water distribution line is supplied to the water tank can save the heat amount for heating the water in the water tank, and is very economical. .
