Abstract

A liquid immersion cooling tank includes a reservoir and a liquid flow tube. The reservoir contains an insulating coolant to immerse an electronic device. The liquid flow tube includes an adjusting member. The reservoir includes an inlet and an outlet. The inlet and the outlet are respectively arranged at opposite ends of the electronic device. The liquid flow tube is located inside the reservoir. The liquid flow tube is coupled to at least one of the inlet and the outlet. The adjusting member faces the electronic device to control an amount of inflow or outflow of the insulating coolant. When the electronic device is immersed in the reservoir for cooling, the insulating coolant flows through the electronic device. The liquid flow tube coupled to the inlet or the outlet of the reservoir uses the adjusting member to control the amount of inflow or outflow of the insulating coolant.
