HEATING METHOD OF TEST ROOM IN CORROSION TEST DEVICE

摘要

PURPOSE:To perform highly accurate temperature adjustment by using a steam as a heat medium, and enabling a specified temperature to be attained quickly. CONSTITUTION:The test room has the double structure of an inner tank and an outer tank. The gap between the inner tank and the outer tank forms a hermetically sealed space. A space is provided between the upper surface of a small amount of water 11 which is put in the space at the bottom and the lower surface of the wall of the inner tank at the bottom. One circuit is composed of a heater 10 in the water, a temperature adjusting sensor 13, and a temperature adjuster 13'. The other circuit is composed of the other heater 10, a temperature adjusting sensor 14 in the test room, and the temperature adjuster 14'. The steam generated when the water is heated at a temperature less than 100 deg.C is condensed on the entire surface of the inner tank wall surrounding the test room 5, and the condensed water quickly flows down or drips. The temperature of a small amount of the water in the bottom space and the test room is adjusted by the two-circuit system.
