Apparatus with immersion bath and immersion bath

摘要

The present application discloses a liquid immersion tank which can withstand the load of a coolant while maintaining dimensional accuracy even though it is made of resin. A liquid immersion tank disclosed in the present application includes a tank main body capable of housing an electronic device and filled with a fluorine-based insulating refrigerant, a fixing portion provided on the inner wall surface of the tank main body, to which the electronic device is fixed, Wherein the tank body has a volume change rate of 2% or less when immersed in a fluorine-based insulating refrigerant and a linear expansion coefficient of 15 10^-5/ K or less.
