CONSTANT TEMPERATURE LIQUID CIRCULATING APPARATUS

摘要

An apparatus for circulating a constant temperature liquid is provided to remove a heat insulation material from a main tank by keeping warmth and adjusting a liquid level of a constant temperature liquid contained in the main tank, thereby reducing size and weight and reducing manufacturing cost. A main tank(2) has a bottom and a closed cover for containing a temperature-controlled constant temperature liquid(1). A sub tank(3) has a bottom and a closed cover, wherein the main tank is arranged inside the sub tank. A transfer pipe(5) and a returning pipe(6) connect a load(4) to supply the constant temperature liquid with the main tank. A circulation pump(7) circularly supplies the constant temperature liquid to the load through the transfer pipe and the returning pipe. A gap(9) is interposed between the sub tank and the main tank as a heat insulation layer. A liquid level adjusting device adjusts a liquid level in the main tank by supplying and discharging the constant temperature liquid between the gaps.
