Abstract: An immersion cooling system includes a cooling tank, a housing and a valve. The coolant tank is configured to accommodate a liquid coolant and an electronic device immersed in the liquid coolant. The housing covers a side of the cooling tank and thereby forms an enclosure. The valve has two ports, one of which communicates with the enclosure and the other communicates with a part of the cooling tank above the liquid coolant. The valve is configured to open in response to a gas pressure inside the cooling tank exceeding an upper limit.

Abstract: An immersion cooling system is provided. It includes a pressure seal tank, an electronic module, a blower, and a distributor plate. The pressure seal tank contains a cooling liquid, and a gas outlet is disposed on the top or a sidewall of the pressure seal tank, a gas inlet is disposed on the bottom of the pressure seal tank. The gas outlet is higher than the liquid level of the cooling liquid. The electronic module is disposed in the pressure seal tank and immersed in the cooling liquid. The blower is communicated with the pressure seal tank and configured to extract the gas from the gas outlet and inject the gas into the pressure seal tank via the gas inlet. The distributor plate is disposed in the pressure seal tank and located between the electronic module and the gas inlet.

Abstract: A working fluid recovery device includes an air moving unit, a water removal unit, a working fluid recovery unit, a condenser, and a working fluid collection tank. The air moving unit is configured to suck in a mixed gas including a non-condensable gas, a steam and a vapor phase of working fluid. The water removal unit is connected to the air moving unit, and configured to remove the steam. The working fluid recovery unit is connected to the water removal unit, and configured to recover the vapor phase of the working fluid and exhaust the non-condensable gas. The condenser is connected to the working fluid recovery unit, and configured to condense the vapor phase of the working fluid into a liquid phase of the working fluid. The working fluid collection tank is connected to the condenser, and configured to store the liquid phase of the working fluid.

Abstract: An immersion cooling system includes a cooling tank and a filtration system. The cooling tank is configured to accommodate a liquid coolant and an electronic device immersed in the liquid coolant. The filtration system includes a pipeline, a pump, a filter and a cooling device. The pipeline is in fluid communication with the cooling tank. The pump is disposed in the pipeline and is configured to drive the liquid coolant to flow through the pipeline. The filter is disposed in the pipeline and is configured to filter the liquid coolant. The cooling device is connected to the pipeline and is configured to cool the liquid coolant. The pipeline has an inlet connected to the cooling tank. The cooling device is located between the pump and the inlet of the pipeline.

Abstract: An immersion cooling system includes a pressure seal tank, an electronic apparatus, a pressure balance pipe and a relief valve. The pressure seal tank is configured to store coolant. A vapor space is formed in the pressure seal tank above the liquid level of the coolant. The electronic apparatus is completely immersed in the coolant. The pressure balance pipe has a gas collection length. The first port of the pressure balance pipe is disposed on the top surface of the pressure seal tank. The relief valve is disposed on the second port of the pressure balance pipe. The second port is farther away from the top surface of the pressure seal tank than the first port. The gas collection length of the pressure equalization tube allows the concentration of vaporized coolant at the first port to be greater than the concentration of vaporized coolant at the second port.

Abstract: An immersion cooling system includes a tank, an isolation plate and a condenser. The tank includes a base plate and a sidewall connected with the base plate. The sidewall defines with the base plate a space configured to accommodate a cooling liquid. The isolation plate connects with the sidewall or the base plate and divides the space into a first subsidiary space and a second subsidiary space. The first subsidiary space is configured to accommodate electronic equipment which is immersed in the cooling liquid. The isolation plate and the base plate are separated from each other. The sidewall surrounds the condenser. A vertical projection of the condenser towards the base plate at least partially overlaps with the second subsidiary space. The electronic equipment evaporates a portion of the cooling liquid to form a vapor. The condenser is configured to condense the vapor into a liquid form.
