CONSTANT TEMPERATURE FLUID CIRCULATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a constant temperature fluid circulation device capable of reducing manufacturing cost by making the whole device compact and light as a tank can do away with a heat insulating material by maintaining temperature of constant temperature fluid kept in a tank while adjusted in temperature and adjusting fluid level by utilizing a same gap formed around the tank. SOLUTION: An entire main tank 2 for keeping the constant temperature fluid 1 of which temperature is adjusted by a temperature adjusting means 8 is supported in a sub-tank 3 with the gap 9 as heat insulating layer around the main tank 2 and the constant temperature fluid 1 is supplied and discharged between inside of the main tank 2 and the gap 9 formed in the sub-tank 3 by a fluid level adjustment mechanism. Thus, temperature of the constant temperature fluid 1 kept in the main tank 2 is maintained and the fluid level is adjusted by utilizing the same gap 9 formed in the sub-tank 3.
